Owners of polyvinyl chloride swimmers are faced with minor but critical repairs. Lisichansk inflatable boats are well-deservedly known for their reliability and affordability, but even the best quality material is subject to wear and tear. The most common problems are with the vessel's leakproof and pumping components, namely air valves.
Finding the right part can become a real quest if you don't know the exact technical parameters of your vessel. If you don't know the right part, you'll get a bad airborne airborne, which is equivalent to an emergency on the water. buy a valve for the boat LysichankaIt requires a detailed consideration, not a spontaneous solution.
In this article, we will discuss all the nuances of choice, types of designs and ways of self-replacement. You will learn how to distinguish the original from a fake and what tools will be required for quality repairs. Competent approach to maintenance will extend the life of your boat for long seasons of active operation.
Design features of the valves Lysychanka
The boats manufactured in Lisichansk were traditionally equipped with standard inflating elements, which in their design resembled classical petal or screw models, the main difference was in the diameter of the installation hole and the height of the mechanism itself, understanding these differences is critical before buying a new part.
Many models have a combined system where air-valve It was a combination of a reverse valve and an overpressure fuse, and it was an engineering solution that avoided breaking the seams when the boat overheated in the sun, but over time, the spring inside the mechanism could weaken and the rubber seals could swell.
⚠️ Attention: Using a valve with the wrong diameter of the landing hole will lead to leaky gluing. Even a quality glue will not be able to compensate for the gap of more than 0.5 mm between the metal and PVC tissue.
Modern analogues that are available on the market often have a versatile design, but require careful selection. It is important to pay attention to the material of manufacture: brass and silimine alloys behave differently in aggressive aqueous environments. Brass is less prone to corrosion, but heavier, whereas modern composites are lighter, but can be less durable when mechanically impacted.
Type sizes and compatibility of parts
The inflatable boat parts market is saturated with supplies, but not all of them are suitable for Soviet and post-Soviet models from Lisichansk. The standard diameter for most civilian boats of the period was considered to be 38 mm in size, but there were exceptions.
To determine the type of part you need, you need a caliper or a ruler with high precision, you need to measure the inner diameter of the hole in the cylinder where the metal part is inserted, and you also take into account the height of the thread or landing pad, because too high a valve can interfere with the installation of seats or transponders.
Below is a table that helps you navigate the main parameters:
| Valve type | Hole diameter (mm) | Case material | Compatibility |
|---|---|---|---|
| Standard Lysichanka. | 38 ± 0.5 | Brass/Silumin | Old PVC models |
| Universal screw | 38-40 | Plastic/Metal | Most PVC boats |
| Herbal valve | 40 | brass | Motorboats |
| Petal (old) | 36-38 | aluminum | Models up to 1995 |
When choosing a model, preference should be given to rubber-sealers Cheap, low-cost, rubbers are often hard rubber that cracks in the cold or in the long run, and if you plan to go fishing in the cold season, that becomes a defining parameter.
Before ordering a new part, take a photo of the old valve from different angles and send the photo to the seller. This will eliminate errors in the selection of diameter and type of thread.
Where to buy original parts
The question is where buy a valve for the boat LysichankaThe corporation is relevant for many fishermen, as the production of original components in the city itself could be suspended or changed, and the main channels of supply are now specialized online stores, water-motor markets and announcement platforms.
When buying online, be sure to check the reviews of the seller and check the country of the manufacturer of the parts. Chinese counterparts can cost less, but their geometry is often different from the original, that complicates the installation process.
- 🛶 Specialized boating stores - here the chance to find the original or high-quality analogue is higher.
- 🔧 Fishing markets and fairs allow you to visually assess the quality of metal and rubber before buying.
- 💻 Large marketplaces are a wide choice, but a thorough check of the specifications in the description of the product is required.
- 🏭 PVC boat factories – sometimes sell parts directly or send them to dealers.
If you are in Luhansk or nearby regions, it makes sense to go to local boat repair service centers, which often have leftovers or can order the right part in bulk, especially for rare modifications that have already been discontinued.
⚠️ Warning: Beware of offering to buy an "original valve" at a price well below market price, and it is highly likely to be a cheap silumin fake that will burst at the first serious pump.
Replacement tools and materials
The process of replacing the air valve requires not only the new part, but also the right tools, so without preparation, you can damage the fabric of the cylinder or incorrectly install the element, which will lead to re-pressurization. Prepare the workplace in advance.
You're going to need a toolbox that most men have in their garage, and the key to tools is clean and healthy, and the dirt or oil on the tools can get under the glue or inside the machine, disrupting the machine.
☑️ Valve replacement tools
To dismantle an old valve, you often need a key-gate that came with the boat, and if it's lost, you can make a metal plate analog, or you can use pliers with soft sponges to keep the edges from breaking, and you can also use a knife to carefully cut off the remnants of old glue.
Pay special attention to the choice of adhesives. PVC fabrics use special two-component polyurethane adhesives. A normal "moment" or silicone will not provide the necessary strength and elasticity of the seam, which will be subjected to constant stretching.
Technology of valve replacement DIY
Valve replacement is a procedure that is available even to a beginner if you act consistently and without haste. Violation of gluing technology is the main cause of failure. First, you need to fully deflate the cylinder and provide access to the inside and outside of the material.
The removal of the old element begins with the twisting of the inside of the element, if the valve is squirt, you can carefully warm the place of installation with a hairdryer, but do not overheat the fabric above 60-70 degrees. After removing the metal part, carefully clean the surface of the residues of rubber and glue.
Procedure:1. Degrease the installation site with alcohol.
2. Apply the first layer of glue on the fabric and allow it to dry for 10-15 minutes.
3. Apply the second layer and dry again to a sticky state.
4. Set a new valve and press it tightly.
5. Twistle the inside with a key.
After installing a new one The air valve needs to be allowed to be fully polymerized, and the drying time depends on the ambient temperature and the type of glue, usually 12 to 24 hours, and early pumping of the boat can displace the element before the glue solidifies.
What to do if the thread is broken?
If the valve's internal thread is damaged, do not force it to twist, use a gauge of the appropriate diameter to repair the thread, or replace the entire valve to avoid pressure air poisoning.
Pressurization and care
After drying time has expired, you need to do a test. Pump the boat to working pressure, but do not pump it right away. Leave it for a few hours, preferably in a warm room, and watch the pressure gauge (if any) or feel the joints.
You can use a soap solution to look for micro-leaks, apply the foam to the valve installation site, watch for bubbles, even small bubbles indicate leakage, which will require a repeat of the gluing procedure.
- 🧼 Rinse the valve regularly with clean water after each fishing trip to remove sand and salt.
- 🌡️ Keep the boat deflated in a dry place, avoiding direct sunlight.
- 🔧 Once a season, lubricate the threaded valve joints with silicone lubrication to prevent acidification.
The proper maintenance of the valve extends the life of the whole boat, and the sand that gets into the mechanism acts like an abrasive, destroying the sealing rings. maintenance It should be regular, not just because of the breakdown.
Well, surface preparation and aging glue drying time is 90 percent of the success of valve replacement. Don't rush to pump the boat right after assembly.
Frequently Asked Questions (FAQ)
Can I use a valve from another boat, for example, Ufimki?
Often the diameters are the same (38 mm), but the height and shape of the washer may differ. It is recommended to try on the part or measure the height of the threaded part.
What is better to glue the valve: cold or hot?
For home renovations, the cold method using two-component polyurethane adhesives is preferred. The hot method requires an industrial hair dryer and skill, as there is a high risk of burning through the PVC fabric.
How often should I change the valve on the boat?
When properly operated and maintained, the valve lasts for decades, and only needs to be replaced if mechanical damage, metal corrosion or leakage is lost that cannot be repaired by replacing the seal.
What to do if the valve poisons the air?
First, try to clean it of dirt and sand. If that doesn't work, check the integrity of the rubber pad. Often, it's enough to replace the pad or petal itself without changing the entire metal body.
Boat repairs are not only cost savings, but also safety on the water. buy a valve for the boat Lysichanka And if you put it in, you can keep it in perfect condition, and you can use technology, you can use quality materials, and your boat will last you for years to come.
