Description

Technical Field

[0001] The utility model relates to the technical field of V-ring surface control valves, in particular to a special V-ring surface control valve. Background Technique

[0002] A V-ring surface control valve is an angular stroke control valve that controls the fluid by rotating a V-notch spherical valve plate against the sealing surface within a small opening range. While increasing the regulation ratio, the V-notch spherical valve plate also has a shearing effect on the sealing ring during throttling. Therefore, it is suitable for control systems requiring a large regulation ratio and for controlling fibrous fluids and slurry-like fluids. It is widely used in industries such as petroleum, chemical, electric power, metallurgy, steel, paper, medicine, food, textile, and light industry.

[0003] At present, during the use of a manually adjusted V-ring surface control valve, there is no corresponding protective structure at the drill pipe, and it is prone to accidental touch problems, resulting in the opening or closing of the control valve, posing a greater hidden danger. Content of the Utility Model

[0004] To solve the defects existing in the prior art, the utility model provides a special V-ring surface control valve.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] The special V-ring surface control valve of the utility model includes a valve body. A valve rod is rotatably arranged inside the valve body. The top end of the valve rod is installed with a turning handle through a locking mechanism. The bottom end of the valve rod extends into the valve body and is fixed with a V-shaped valve ball. A sealing block that cooperates with the V-shaped valve ball is hermetically slidably arranged at the position of the water inlet inside the valve body. A sealing gasket is installed on one side of the sealing block close to the V-shaped valve ball. A filtering component is arranged at the position of the water outlet inside the valve body.

[0007] As a preferred technical solution of the utility model, an elastic block is fixed inside the valve body, and the sealing block is fixedly connected with the elastic block.

[0008] As a preferred technical solution of the utility model, the filtering component includes a mounting frame fixed inside the valve body, and a filter screen is installed on the side of the mounting frame.

[0009] As a preferred technical solution of the utility model, a plurality of sliding grooves are formed on the mounting frame. Connecting rods are slidably arranged inside the sliding grooves. Limiting plates are fixed at the ends of the connecting rods. Channels for the connecting rods and the limiting plates to pass through are formed on the filter screen.

[0010] As a preferred technical solution of the present utility model, a moving plate that is hermetically slid inside the sliding groove is fixed at the end of the connecting rod. A spring is fixed to the side of the moving plate, and the end of the spring is fixed to the inner wall of the sliding groove.

[0011] As a preferred technical solution of the present utility model, the locking mechanism includes two clamping frames respectively fixed on the surfaces of the handlebar and the valve body. The two clamping frames are provided with cooperating teeth, and an elastic telescopic rod is fixed between the handlebar and the valve rod.

[0012] The beneficial effects of the present utility model are:

[0013] 1. For this special V-shaped ring surface control valve, by setting the valve body, valve rod, handlebar, locking mechanism, V-shaped valve ball, sealing block, sealing gasket and filtering component, and using the cooperation between the handlebar and the locking mechanism, the rotation angle of the valve rod and the V-shaped valve ball can be adjusted. Furthermore, the V-shaped valve ball cooperates with the valve body to realize the work of controlling the opening of water flow discharge and the size of water flow discharge. The sealing block and the sealing gasket can improve the sealing performance between the V-shaped valve ball and the valve body when intercepting water flow. At the same time, the filtering mechanism filters impurities in the water flow to avoid affecting the control valve behind.

[0014] 2. For this special V-shaped ring surface control valve, by setting the elastic block, the elastic block can adaptively adjust the sealing block, reduce the situation of the V-shaped valve ball being stuck. At the same time, when the position of the V-shaped valve ball is fixed for blocking, under the action of the elastic block, the sealing block and the sealing gasket can be more closely attached to the V-shaped valve ball, improving the sealing performance.

[0015] 3. For this special V-shaped ring surface control valve, by setting the mounting frame, filter screen, connecting rod, limiting plate, moving plate and spring, the mounting frame is used to install and place the filter screen. Through the cooperation between the connecting rod and the limiting plate, when the limiting plate rotates to be perpendicular to the channel, the limit fixation of the filter screen can be realized. When the limiting plate rotates to be horizontal with the channel, the fixation of the filter screen is released, which is convenient for the installation and disassembly of the filter screen, with simple operation and improved convenience. The elasticity of the spring can drive the moving plate to drive the connecting rod to move, and the connecting rod drives the limiting plate to move, so that the limiting plate can be closely attached to the filter screen, improving the stability of fixation.

[0016] 4. For this special V-shaped ring surface control valve, by setting the clamping frame and the elastic telescopic rod, the cooperation between the two clamping frames can fix the positions of the handlebar and the valve rod, preventing the problem that the valve rod shakes and drives the V-shaped valve ball to shift during use. The elastic telescopic rod enables the handlebar to move up and down to release the locking of the two clamping frames for adjusting the rotation angle of the handlebar, further adjusting the rotation angles of the valve rod and the V-shaped valve ball. At the same time, the elastic telescopic rod can drive the handlebar to automatically return to its original position, making the two clamping frames closely engaged, improving the stability of fixation.

The bottom end of the valve stem 3 extends into the valve body 1 and is fixed with a V-shaped valve ball 2. A sealing block 5 that cooperates with the V-shaped valve ball 2 is hermetically and slidably arranged inside the valve body 1 at the position of the water inlet.

Furthermore, the V-shaped valve ball 2 cooperates with the valve body 1 to realize the work of controlling the opening of water flow discharge and the size of water flow discharge. By using the sealing block 5 and the gasket 6, the sealing performance between the V-shaped valve ball 2 and the valve body 1 can be improved when the water flow is blocked. At the same time, the filtering mechanism filters the impurities in the water flow to avoid affecting the control valve at the rear.

[0028] Among them, an elastic block 7 is fixed inside the valve body 1, and the sealing block 5 is fixedly connected to the elastic block 7;

[0029] By setting the elastic block 7, the elastic block 7 can play an adaptive adjustment role on the sealing block 5 to reduce the situation of the V-shaped valve ball 2 being stuck. At the same time, when the position of the V-shaped valve ball 2 is fixed for blocking, under the action of the elastic block 7, the sealing block 5 and the gasket 6 can be more closely attached to the V-shaped valve ball 2 to improve the sealing performance.
