Description

Technical Field

[0001] The utility model relates to the field of valve seat installation, in particular to a ball valve seat installation mechanism. Background Art

[0002] Ball valves are a common valve structure. They primarily serve to cut, distribute, and redirect the flow of media in pipelines, making them widely used in the petroleum, chemical, power generation, aviation, and plumbing industries. The valve seat is a removable surface component within the valve that supports the valve core in the fully closed position and forms a sealing element. To install a ball valve seat, attach the seat to the valve body, then merge the main and auxiliary valve bodies. The two seats then press the ball core into place, which is then secured with bolts.

[0003] A Chinese patent discloses a ball valve seat installation mechanism with the publication number CN213497563U. In this patent, the structure of the ball valve seat installation mechanism is mainly composed of a base, a valve seat clamp that movably clamps the valve seat at the bottom of the base, a valve body clamp that movably clamps the valve body below the base, and a positioning rod and a pressure rod that are movably installed above the valve seat clamp. During use, the positioning rod is first lowered and passed through the valve seat into the valve seat hole of the valve body for positioning. Then, the pressure rod is lowered to push the valve seat out of the valve seat clamp. The valve seat can be quickly pushed along the positioning rod by the lower end of the pressure rod to be installed in the valve seat hole. When the positioning rod and the pressure rod are both raised and reset, the valve seat can wait for the next round of assembly process. Obviously, no human intervention is required in the above-mentioned valve seat assembly process. The assembly process is convenient, fast, accurate, and highly automated. It can also better improve production efficiency, reduce labor intensity, and ensure product quality.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, during the installation process of the ball valve body and the valve seat, the positioning rod and the pressure rod of the installation mechanism move up and down repeatedly, resulting in friction between them and other limiting components. The repeated friction will cause wear on the connection, affecting the subsequent normal use of the installation mechanism.

[0006] (2) In the prior art, when the valve seat and the valve body are connected and installed using the installation mechanism, the valve seat and the valve body have different sizes and models, resulting in the installation mechanism being unable to adapt to all valve seats and valve bodies, affecting the applicability of the mechanism.

[0007] (3) In the prior art, the valve seat is pressed into the inner side of the valve body by the downward pressing of the pressure rod. When the pressure rod is pressed downward, a certain pressure is exerted on the valve body, which may cause certain damage to the valve body and valve seat, affecting the subsequent normal use of the ball valve.

[0008] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
