Knife Gate Valve Structure and Working Principle
Knife gate valve, also called knife type gate valve, is a kind of gate valve. The structural feature of the knife gate valve is that there is an oblique cut at the bottom of its valve plate. Like a knife edge, this knife-shaped oblique cut can easily cut off the medium circulating in the pipeline, […]
Sealing Surface Structure of Handle Wafer Type Butterfly Valve
The sealing surface structure of the handle wafer butterfly valve is the key to ensure the reliable sealing of the valve and an important basis for judging the performance of the valve. The sealing performance is related to whether the butterfly valve can perform normal adjustment and cut off the medium work. In general, the […]
What is the principle of triple eccentric butterfly valve
Triple eccentric butterfly valve is a kind of butterfly valve with outstanding performance in industrial pipelines. According to the sealing form, triple eccentric butterfly valve belongs to the category of hard sealing butterfly valve. Therefore, the triple eccentric butterfly valve has the characteristics of a hard-sealed butterfly valve, which is resistant to high temperature, erosion, […]
Properties of triple eccentric butterfly valve
Performance advantages of triple eccentric butterfly valve: 1. It integrates adjustment and cut-off, and has strong controllability. The design of the new triple eccentric butterfly valve adopts a double safety structure. In order to prevent the deformation of the disc, the dislocation of the valve stem, and the occlusion of the sealing surface caused by […]
