Abstract

The invention relates to the technical field of check valves, in particular to a check valve capable of being stopped for high-temperature fluid and valve clack machining equipment of the check valve. The check valve capable of being stopped for the high-temperature fluid comprises a shell part, a pressing part, a rotating part, a rebounding part, a valve clack and a circulating part, wherein the lower end of the pressing part penetrates through the lower part of the top of the shell part so as to be connected with the valve clack; and the pressing part is in threaded connection with the top of the shell part in a sliding mode. The valve clack machining equipment of the check valve capable of being stopped for the high-temperature fluid comprises a first support, a second support, a milling part, clamp parts, a rotating part, a tool taking part and a tool rest part, wherein the second support is connected with the first support in a sliding mode; the milling part is connected with the front end of the second support in a sliding mode; the rotating part is rotatably connected with the first support; the clamp parts are symmetrically arranged at the front end of the rotating part; the tool rest part is rotatably connected with the front end of the first support; and the tool taking part is arranged in the first support. The invention further provides the check valve capable of being stopped for the high-temperature fluid and an application method of the valve clack machining equipment of the check valve.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a stop check valve for high-temperature fluid and valve disc processing equipment thereof. Background technique [0002] Check valve refers to the valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. According to the structure, the check valve can be divided into three types: lift check valve, swing check valve and butterfly check valve. Lift check valve can be divided into two types: vertical and horizontal. The check valve used in oil exploration pipelines is mainly a horizontal check valve, which mainly has a valve body, a valve seat, a valve disc and a valve cover. The valve body has a liquid inlet channel, a middle cavity and a liquid outlet channel. The channel communicates with the liquid outlet channel ...
