[0002] In some large-scale fluid control applications, the control valves required are relatively large in size. Most existing control valves are circular in structure, which results in relatively low load-bearing capacity of the surrounding structure during use. Gate valves, on the other hand, have difficulty guaranteeing the load-bearing capacity of the main body during use. Due to the large impact forces they are subjected to during use, they require regular maintenance, which is relatively costly. Using multiple valve bodies in combination is not only costly but also reduces the ease of operation during control. Utility Model Content

The internal inclined disc-shaped valve body provides stronger load-bearing capacity during use. The valve mating parts are fitted with spherical surfaces, making it safer and more reliable during use. Control is achieved through an external component on the top, and the inspection ports distributed at different positions on the front and back enable quick maintenance and repair. This makes maintenance more convenient in later use. It can replace multiple existing control valves, resulting in higher control efficiency, lower operating costs, and greater durability. It can meet the needs of applications with high impact strength requirements and has a longer overall service life.

The control connection support is connected to the support frame on the control clearance box located at the upper end of the valve body main frame structure via a valve control support arm. The right side of the valve control support arm is connected to the matching support assembly seat on the control clearance box via a precision adjustment control screw. The movement of the precision adjustment control screw can drive the main valve structure to open and close. The main valve structure and the sealing assembly support are sealed together by a sealing pressure ring and a graphite sealing ring. Convenient maintenance windows are provided on the front and rear sides of the valve body main frame structure, respectively, in the left and right areas of the main valve structure.
