Selection and durability of sealing materials
The sealing ring of the trailer valve is usually made of materials with high wear resistance and strong anti-aging ability, such as fluororubber, polyurethane, silicone, etc. These materials have strong temperature resistance, pressure resistance and corrosion resistance. Materials such as fluororubber can maintain their elasticity and sealing after long-term contact with air and liquid, thereby effectively preventing gas leakage. Over time, the aging problem of the sealing material may cause the sealing performance to decline, so choosing the right sealing material is crucial for long-term use.
Factors affecting the sealing effect
In addition to the quality of the sealing material itself, the sealing effect of the trailer valve is also closely related to the surface finish of the valve seat, the accuracy of installation, and the external stress generated during use. The smoothness and flatness of the valve seat surface directly affect the compression effect of the sealing ring, ensuring that the sealing ring can be evenly compressed to form an effective sealing barrier. If the surface of the valve seat is rough or scratched, it may cause the sealing ring to not fit completely, causing leakage problems.
Influence of the external environment
Trailer valves are often under conditions where the working environment changes greatly, especially in environments with high temperature, low temperature, humidity or high dust, the sealing performance may be affected. Extreme temperatures and environmental conditions may cause the sealing ring material to expand, contract or harden, thus affecting the sealing effect. In cold weather, the sealing material may become brittle, resulting in seal failure; in high temperature conditions, the sealing ring may lose its elasticity due to excessive softening or melting, resulting in air pressure leakage.
In order to avoid the influence of the external environment on the sealing performance, many trailer valves are designed with seal protection measures in mind, such as adding dust protection devices or using anti-pollution sealing materials to prevent dust, sand or other impurities from entering the system, thereby reducing the risk of seal failure. For trailer valves that are used for a long time, regular cleaning and inspection of the valve body and sealing parts are very important maintenance measures.
Regular maintenance and replacement of seals
Although high-quality trailer valves can maintain a good sealing effect for a long time, the sealing materials and seals will inevitably experience aging, wear or hardening as the use time increases. Regular inspection and maintenance are the key to ensuring the sealing effect. Operators need to regularly check the condition of the seals to check for wear, cracks, hardening, etc. Once a problem is found, the seal or other damaged parts should be replaced in time to prevent the occurrence of air pressure leakage.
Maintenance of trailer valves also includes regular inspection of the tightness of the seals to ensure that they are in good contact with the valve seat. If the valve seals are loose or deformed, they should be adjusted or replaced in time. In addition, leakage inspection of hydraulic or pneumatic systems is also part of daily maintenance. Regularly testing system pressure and conducting leakage inspections can effectively avoid accidents caused by poor sealing.
