Open rod elastic seat seal gate valve is the replacement product of traditional gate valve, using the elastic gate plate to produce micro deformation compensation, to achieve good sealing effect, the valve has the advantages of light switch, reliable seal, good elastic memory and long service life, and can be widely used in tap water, sewage, construction, food, electric power, medicine, metallurgy, light textile, etc.
Fatigue life design of bellows compensator According to the failure type and cause analysis, the plane stability, circumferential stability and corrosion resistance of bellows are related to its displacement, namely fatigue life. Too low fatigue life will lead to bellows stability and corrosion resistance decline. According to the test and use experience, the fatigue life of bellows used in heating engineering should not be less than 1000 times.
Large diameter soft seal gate valve underground gate valve and small purpose valve using rubber integral package, in order to produce deformation compensation, so as to achieve good sealing effect, overcome the ordinary gate valve sealing poor, water leakage and rust problems, and more effectively save the installation space.
The products are widely used in water supply and drainage system, fire protection system, and municipal engineering.
