dome valve seal
In addition to the general requirements for sealing materials, dome valve seals also need to pay attention to the following conditions:
(1) Full elasticity and resilience;
(2) Adequate mechanical strength, including expansion strength, elongation and tear strength.
(3) Stable performance, not easy to inflate in the environment, and the heat shrinkage effect (Joule effect) is small.
(4) Easily machined and shaped and can maintain precise dimensions.
(5) The sealing ring of the dome valve does not corrode the contact surface and does not pollute the medium.
The most commonly used and suitable material to meet the above requirements is rubber, therefore washers are mostly made of rubber. There are many types of rubber and new types of rubber are constantly appearing, when designing and choosing it is necessary to understand the characteristics of rubber types and choose them appropriately.
