Different from parallel gate valves, wedge gate valves also have wedge single gate valves. The two sealing surfaces of the most commonly used wedge gate valve form a wedge, and the wedge angle varies with the valve parameters, usually 50. The gate of wedge gate valve can be made into a whole, which is called rigid gate valve; It can also be made into a ram that can produce slight deformation to improve its manufacturability and make up for the deviation of the angle of the sealing surface in the processing process. This kind of ram is called elastic ram.
Wedge gate valves commonly used in the market are generally designed and manufactured according to GB / t12234-2019 standard, with reliable sealing and excellent performance; Generally, wedge type elastic ram structure is adopted, and medium and large diameter rolling bearings are set, so it is easy to open and close; Wedge gate valve has the advantages of simple shape, short structure length, good manufacturing technology and wide application range. Received the welcome of the majority of users.
