Description

Technical Field

[0001] The utility model relates to the technical field of valve connection, in particular to a valve body joint for a high-pressure differential valve. Background Art

[0002] High-pressure differential valves are widely used in modern industry, particularly in the coal chemical, chemical, metallurgical, and petroleum industries. These valves often must withstand extremely high pressure differentials and harsh operating environments, such as those involving highly corrosive media, high temperatures and pressures, and fluids containing solid particles. However, conventional high-pressure differential valve body joints often suffer from poor sealing, leakage, insufficient corrosion resistance, and difficult maintenance, severely impacting production efficiency and safety.

[0003] According to Chinese Patent Publication No. CN 212407858U, a connector between a valve and a joint is disclosed, comprising a joint connector and a valve connector. The joint connector comprises a joint connecting pipe, a protruding pipe edge, and a sealing ring. The joint connecting pipe is a horizontally placed tubular structure, with a connecting thread provided on the left end of the outer surface of the joint connecting pipe. The protruding pipe edge is located at the right end of the joint connecting pipe. The protruding pipe edge is a horizontally placed cylindrical tube. The inner diameter of the longitudinal cross-section of the protruding pipe edge is the same as the inner diameter of the longitudinal cross-section of the joint connecting pipe. The outer diameter of the longitudinal cross-section of the protruding pipe edge is larger than the outer diameter of the longitudinal cross-section of the joint connecting pipe. An annular sealing ring placement groove is provided on the outer surface of the protruding pipe edge, and the center of the longitudinal cross-section of the sealing ring placement groove is located on the same horizontal line as the center of the longitudinal cross-section of the protruding pipe edge. The above-mentioned connection between the valve and the joint is also connected by threads, but the connection is more convenient and quick. However, when the above device is used, the valve is prone to generate eddy currents and disturbances at the throttling position, thereby increasing the noise and vibration of the valve and shortening the service life of the valve.

[0004] Therefore, when the above device is used, eddy currents and disturbances are likely to occur at the throttling position, thereby shortening the service life of the valve. Utility Model Content

A rotating block is rotatably installed on the upper part of the valve connecting pipe near the output end, and a connecting block is rotatably provided on the upper part of the valve connecting pipe near the input end. Stability covers are evenly arranged on the inside of the valve connecting pipe along the length direction, and a guide block is provided on one side of the valve connecting pipe near the stability cover along the length direction.

[0007] More preferably, the inner side wall of the rotating block and the outer side wall of the connecting block are threadedly connected.

[0008] Further preferably, a connecting groove is provided at a position of the connecting pipeline close to the input end of the valve connecting pipe, and the end of the connecting block is clamped in the connecting groove.

The closer the connecting block is to the inner end of the connecting pipe, the stronger the fastening effect of the connecting pipe on the connecting block.

[0018] The prior art discloses a connector between a valve and a joint, comprising a joint connector and a valve connector. The joint connector comprises a joint connecting pipe, a protruding pipe edge, and a sealing ring. The joint connecting pipe is a horizontally placed tubular structure, with a connecting thread provided on the left end of the outer surface of the joint connecting pipe. The protruding pipe edge is located at the right end of the joint connecting pipe. The protruding pipe edge is a horizontally placed cylindrical tube. The inner diameter of the longitudinal section of the protruding pipe edge is the same as the inner diameter of the longitudinal section of the joint connecting pipe, and the outer diameter of the longitudinal section of the protruding pipe edge is larger than the outer diameter of the longitudinal section of the joint connecting pipe. An annular sealing ring placement groove is provided on the outer surface of the protruding pipe edge, and the center of the longitudinal section of the sealing ring placement groove is located on the same horizontal line as the center of the longitudinal section of the protruding pipe edge. The above-mentioned device is used between the valve and the joint. Although the connection is also made by thread, the connection is more convenient and quick. However, when using the above-mentioned device, the valve is prone to generating eddy currents and disturbances at the throttling position, thereby increasing the noise and vibration of the valve and shortening the service life of the valve.

[0019] Therefore, when the above device is used, eddy currents and disturbances are likely to occur at the throttling position, thereby shortening the service life of the valve.

[0020] In response to the above technical problems, this application has made the following designs and concepts: In order to solve the problems existing in the prior art, it is envisaged that the diversion mechanism can have a better effect of conveying liquid than the joint connecting pipe in the prior art, thereby achieving the purpose of stable liquid conveyance.

[0021] The following is combined with Figures 1 to 4 The utility model is further introduced in detail.

[0022] A valve body connector for a high pressure differential valve, such as Figure 1 As shown, it includes a valve connecting pipe 1 and a connecting pipe 2. Furthermore, the valve connecting pipe 1 and the connecting pipe 2 are threadedly connected, and the specifications of the valve connecting pipe 1 and the connecting pipe 2 are the same. A rotating block 3 is rotatably installed on the upper part of the valve connecting pipe 1 near the output end, and a connecting block 4 is rotatably provided on the upper part of the valve connecting pipe 1 near the input end. The interior of the valve connecting pipe 1 is evenly provided with a stabilizing cover 5 along the length direction, and a guide block 6 is provided on one side of the interior of the valve connecting pipe 1 near the stabilizing cover 5 along the length direction.

[0023] Through the mutual cooperation between the rotating block 3, the connecting block 4 and the connecting pipe 2, when in use, the rotating block 3 is clamped in the inside of the connecting pipe 2 through the connecting block 4. The closer the connecting block 4 is to the inner end of the connecting pipe 2, the stronger the fastening effect of the connecting pipe 2 on the connecting block 4. It is then fixed by bolts, thereby improving the stability of the connection between the connecting pipe 2 and the valve connecting pipe 1. Through the stabilizing cover 5 and the guide block 6 arranged inside the valve connecting pipe 1, when the valve connecting pipe 1 transports the liquid to the inside of the valve, the stability of the liquid flow is improved, effectively preventing eddies and disturbances generated by the liquid during flow, and further improving the service life of the valve.

[0024] Specifically, if Figure 2 As shown, the inner wall of the rotating block 3 and the outer wall of the connecting block 4 are threadedly connected.

[0025] Furthermore, when in use, the rotating block 3 is rotated clockwise, and the rotating block 3 drives the connecting block 4 to move on the valve connecting pipe 1 toward the connecting pipe 2, thereby improving the convenience of connection between the valve connecting pipe 1 and the connecting pipe 2.

[0026] Specifically, if Figure 1 and Figure 2 As shown, a connecting groove 7 is provided at the connecting pipe 2 near the input end of the valve connecting pipe 1, and the end of the connecting block 4 is clamped in the connecting groove 7. Furthermore, the shape of the connecting groove 7 is a truncated cone. Furthermore, mounting holes perpendicular to the center of the circle are provided on the connecting pipe 2 at equal intervals along the circumferential direction.

[0027] Furthermore, when the end of the connecting block 4 is clamped inside the connecting groove 7, the closer the connecting block 4 is to the inner end of the connecting groove 7, the stronger the fastening effect of the connecting groove 7 on the connecting block 4, further improving the connection effect of the valve connecting pipe 1 and the stability of the connection of the connecting pipe 2.

[0028] Specifically, if Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, a limit groove is provided on the upper part of the valve connecting pipe 1 and is adapted to the rotation trajectory corresponding to the position of the rotating block 3, and a connecting part is provided inside one side of the rotating block 3 and is adapted to the movable track of the outer wall of the connecting block 4.

[0029] Furthermore, when the rotating block 3 is rotated, the rotating block 3 rotates at the connection position, thereby improving the rotation stability of the rotating block 3. Furthermore, when the rotating block 3 is rotated, the connecting block 4 moves toward the connecting pipe 2 through the thread, and the end of the connecting block 4 is clamped in the connecting groove 7, thereby further improving the stability of the connection between the rotating block 3 and the connecting block 4.

[0030] Specifically, if Figure 2 、 Figure 3 and Figure 4 As shown, the inner side wall of the guide block 6 is evenly provided with guide grooves toward the center of the circle along the circumferential direction, and the center position of the guide block 6 is open.

[0031] Furthermore, when in use, the liquid flows through the connecting pipe 2 to the inside of the valve connecting pipe 1. When the liquid is on the guide block 6, the guide block 6 guides the liquid to the position of the stabilizing cover 5, thereby ensuring the stability of the liquid flow to a limited extent.

[0032] Specifically, if Figure 2 and Figure 4 As shown, the input end of the stabilizing cover 5 is arranged at the middle position of the output end of the guide block 6, and through holes are arranged on the stabilizing cover 5 at equal intervals along the circumferential direction.

[0033] How it works

[0034] When in use, the connecting pipe 2 and the connecting groove 7 are moved to the input end of the valve connecting pipe 1. At this time, the rotating block 3 is rotated clockwise, and the rotating block 3 drives the connecting block 4 on the valve connecting pipe 1 to move toward the connecting pipe 2, so that the end of the connecting block 4 is clamped inside the connecting groove 7. The closer the connecting block 4 is to the inner end of the connecting groove 7, the stronger the fastening effect of the connecting groove 7 on the connecting block 4. Then, the connecting block 4 is fastened to the inside of the connecting pipe 2 by bolts. When liquid is transported to the inside of the valve, when the liquid is on the guide block 6, the guide block 6 guides the liquid to the position of the stabilizing cover 5. Finally, the liquid moves through the inside of the stabilizing cover 5, and the liquid moves to the inside of the valve through the output end of the valve connecting pipe 1, further improving the stability of the liquid flow.

[0035] This specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of protection of the utility model, they are protected by patent law.
