The situation when your flyboat It starts to lose pressure in the valve area, it always takes you by surprise, especially if you're already at the water or in the process of preparing for the exit, and it's not just an inconvenience that can ruin fishing, but it's a real safety risk, because the soft side reduces the stability of the vessel, and most often the problem is not the global damage to the cylinder, but the small part that can be repaired on your own with a minimum set of tools.
Before you panic or carry the boat to the service, you need to conduct a competent diagnosis to understand where exactly the air leak occurs. Often the owners sin on the valve itself, although it may be a matter of contamination or improper installation of the spool. Screwing and petal The sealing systems have their own peculiarities, but they have similar fault-finding principles, and in this article we will discuss a step-by-step algorithm of actions that will help you return the sealed vessel.
It is important to understand that even high quality PVC And a reliable valve requires regular maintenance and inspection, and ignoring the first signs of air intoxication can lead to a major overhaul with a complete underbody glue by next season, so if you find a problem, act consistently and carefully.
Primary diagnosis: search for the location of the leak
The first step is always to do a thorough visual and tactile check, pump the balloon to operating pressure and carefully examine the area around the valve. Often the leakage occurs not through the mechanism itself, but through the mechanism. microcrack c c fabric around the seat, which may have been formed due to overinflatation or mechanical impact.
The surest way to find a hole or a loose fit is to use a soap solution. Spread a lot of foam on the valve and the tissue around it. If you see bubbles growing and bursting, that means that the air is coming out here. Be careful: sometimes the air can come out slowly, and the bubbles only appear after a few seconds.
⚠️ Attention! Don't try to find a leak by listening to the hissing. In the wind or in a noisy room, this method is ineffective, and soap solution will show a problem even with microscopic etching.
If the soap test shows that the bubbles are coming from the thread or from the center of the valve, the problem is localized. If the foam bubbles along the edge where the valve is glued into the cylinder, the situation is more complicated and may require re-adjustment, but in 80% of cases, you can get by with replacing the internal components.
Use liquid soap or shampoo for solution – they create a more viscous foam that is better held on the vertical surfaces of the balloon than regular household soap.
Valve design: screw and petal types
Understanding your inflating system is critical to successful repairs, and today’s boats are most commonly used for two main types of valves: screw valves (often called “bravos” or “bayards”) and petals (membranes). Screw valve works on the principle of threaded connection, where tightness is ensured by a tight fit of threads and rubber seals.
Petal valve It's different, it's a spring-loaded petal membrane that opens when you press the center and closes when you pull a spring, and leaks in these systems often involve a grain of sand getting under the petal or weakening the spring, and the systems are different when you disassemble them, and it's important not to confuse the sequence.
Also worth mentioning are the combined systems, where the outer cap can act as a return valve. silicone padswhich may eventually dry or deform, ceasing to perform its function.
What is the difference between High Pressure valves?
High-pressure valves have a reinforced design and often an additional locking mechanism to prevent spontaneous unwinding when pumped with a compressor. Their interior is more massive.
Cleaning and maintenance of the valve system
One of the most common but common reasons why a boat descends is the elemental pollution: sand, fine grass or salt (if you have been swimming on the sea) can get between the O-rings.
Use a special key, which usually comes with a boat (or remix) to unscrew the core. Wash all the details with clean fresh water. Pay special attention to the threads and sealing cuffs. If you see plaque on the thread, it can be carefully removed with a soft brush, but do not use aggressive chemistry that can eat away. plastic.
- 🧼 Carefully wash the inner valve thread from sand and silt.
- 🔍 Check the rubber seals for cracks or bullies.
- 💨 Blow the valve with compressed air or just blow heavily to expel the water.
- 🧴 Lubricate the thread with silicone lubrication for easier rotation and better sealing.
Once cleaned, reassemble the valve and repeat the soap solution test. Often, this simple procedure will return the seal to the boat without having to replace parts. Remember, regular maintenance prolongs the life of the product.
☑️ Annual valve maintenance
Replacement of the spool and sealing rings
If cleaning did not help, then consumables were worn out. The golden The lens (central pin with spring) can lose its elasticity or get mechanical damage, and the lens (cuffs) tan over time and stop tightly fitting the parts.
To replace, you will need a remix that can be bought at any boating store. It is important to choose the components exactly for your type of valve, as the thread sizes and diameters may vary from manufacturer to manufacturer, such as: Nissamarine, Flagship or hunter.
| Component | Signs of wear and tear | Replacement frequency | Cost |
|---|---|---|---|
| The golden (valve) | Does not keep air when closing | As necessary | Low. |
| Rubber cuff | Cracks, loss of elasticity | Once in 2-3 seasons | Low. |
| spring | Tension relief | Rarely. | Low. |
| Valve cover | Broken carving or ears | When it breaks down. | Medium |
The replacement is simple: twist the old element, insert a new one, making sure that it sat smoothly and without distortions. It is critically important not to drag the thread during assembly, so as not to tear the plastic thread inside the valve glass. Write to the point by hand, without using excessive force with the key.
Repair of the valve insertion site
The worst scenario is when air comes out from under the valve, where it's glued into the balloon, and it's a violation of the adhesive seam, and it can be a factory defect, a boat inflated into the sun, or a mechanical injury.
If the damage is small, you can try to glue the joint on the outside using a two-part polyurethane glue, which means you degrease the surface, clean it with fine sandpaper and apply glue, but this method often has a temporary effect.
⚠️ Attention! If the valve is cruising in the fabric or has detached significantly, external repair is useless, it requires dismantling the valve, cleaning the inner surface of the cylinder and pasting a new valve with a warm-up hairdryer.For quality repair of the place of sticking, the "petaka" method is often used - patching over the valve with a hole under it, or full gluing. This is a laborious process that requires the skill of working with the valve. hairdryer If you're not confident in your own abilities, you should leave the job to the professionals.
Prevention and proper storage
To keep the valve-flowing problem from becoming a regular problem, it's important to keep and operate the boat properly. The main enemy of the valves is ultraviolet and dirt. After each fishing, wash the boat with fresh water, washing away the sand, which is an abrasive for seals.
When storing, do not leave the boat fully pumped for a long time, especially in a warm room. Excess pressure can deform the valve system. It is also recommended to periodically lubricate the valve threads with silicone so that they do not "feel."
- ☀️ Keep the boat in a dark place protected from direct sunlight.
- 🧹 Always clean the valves of dirt before twisting the caps.
- 📉 Reduce pressure during long-term storage or transportation in the heat.
- 🔧 Once a season, check the force of the valve tightening.
Keeping these simple rules in mind will allow your boat to last for years without major repairs, and remember that (prevention) is always cheaper and easier than remediation.
Regular washing of boats and lubricating valves with silicone reduces the risk of leaks by 90% and prolongs the life of sealers.
Frequently Asked Questions (FAQ)
Why does the boat only go down in the sun?
It's a physical law that when you heat up, the air inside the cylinders expands and the pressure increases. If the valve is a little bit dirty or worn out, the increased pressure starts to squeeze the air through the microscopic gaps, and the glue softens in the sun if there's a problem with sticking.
Can I use a car sealant to repair the valve?
Automotive sealants often contain acids or substances that destroy PVC and seal rubber. Use only specialized PVC adhesives or silicone lubricants intended for inflatable products.
How to pump a boat if the valve breaks right on the pond?
If the valve doesn't hold at all, you can try to temporarily plug it with a tightly coiled piece of cloth or a cork wrapped with tape to get to the shore, but full operation with a broken valve is impossible and dangerous.
Which glue is better for sticking the valve?
Two-component polyurethane adhesives (such as Kleyberg, Teknipol or specialized adhesives for PVC boats) are best suited to create an elastic and water-resistant seam that withstands the deformation of the cylinder.
Do I need to lubricate the valve thread with oil?
Mineral oils can't be used, they corrode rubber. To lubricate threads and seals, use only silicone lubricant. It's inert to the boat's materials and retains its properties in the water.
