The importance of valve seals
Sep 19, 2021
Valves are mainly used to open and close pipelines, control the direction of fluid, adjust and control the parameters of the transport medium range, what are the adjustment parameters? Such as: temperature, pressure, flow. The valve is used as the accessory of the pipeline, and the valve sealing ring is used as the auxiliary sealing part of the valve. According to the function of the valve and seals, it can be divided into shut-off valve, check valve and regulating valve; the sealing ring prevents leakage and foreign objects intrusion.
The key to the importance of the effect of the valve seals is the loss and waste of energy and resources such as running, leaking, dripping, and leaking in the sealing. Serious operation failures will occur, fires, explosions, and life safety issues. Moreover, the leakage of valve sealing ring, the quality of mechanical equipment and weapon equipment accidents, is more or less caused by the failure of the seal; the valve O-ring is the key to protect the mechanical performance from external influences, and is to ensure the safety of life The premise that an effective sealing ring brings not only the saving of resources and energy, the efficiency of work, but also the progress of today's sealing technology. Therefore, the use of high-quality sealing rings is one of the important choices.
As a commonly used control pipeline component, valves have important functions for the control and adjustment of the gas, liquid and other media of the pipeline seal. In the industrial industry, the problem of valve sealing ring is also an indispensable technology, not only for construction, petrochemical, shipbuilding, machinery manufacturing, energy, transportation, etc., the same cannot do without sealing technology.
As the valve sealing ring, commonly used materials: nitrile butadiene rubber, cyanide butadiene rubber and silicone rubber. Nitrile rubber has good oil resistance and is used in the manufacture of oil-resistant rubber products. It has good oil resistance, high abrasion resistance, good heat resistance and strong adhesion. The aging resistance, heat resistance, and abrasion resistance of cyanogen-butadiene rubber are far superior to natural rubber, and it has received particular attention in the rubber industry. Silicone rubber has good electrical insulation, resistance to oxygen, aging, and chemical stability.
