Description

Anti-rotation petroleum valve Technical Field The utility model belongs to the technical field of valves, and particularly relates to an anti-autorotation petroleum valve. Background Petroleum valves play a vital role in the petrochemical industry, and primary functions include switching on and off media, preventing media pressure from exceeding a specified value, etc., to ensure safe operation of a pipeline or equipment. ‌ A Through searching, the Chinese patent with the bulletin number of CN214789274U discloses a high-tightness petroleum valve, which comprises a petroleum valve main body, wherein first metal flanges are symmetrically arranged at two ends of the outer side wall of the petroleum valve main body, so that the stability of valve connection is ensured, and the service life of the valve is prolonged. However, there is still a disadvantage in that in the conventional practice, the valve may be accidentally changed in its open/close state once it rotates due to the design of the valve or the influence of external force, thereby causing erroneous opening or closing of the pipeline. Disclosure of utility model The utility model aims to provide an anti-autorotation petroleum valve so as to solve the problems in the background technology. In order to achieve the above purpose, the technical scheme includes that the valve comprises a valve body, wherein the valve body comprises a valve body, a valve cover, a valve seat, a valve plate and a valve rod, the top of the valve body is fixedly connected with a shell, the valve rod penetrates through the shell, a groove is formed in the top of the shell, a sliding block is connected in the groove in a sliding mode, limit grooves matched with the sliding block to slide are symmetrically formed in the outer wall of the valve rod, a plurality of slots are uniformly formed in the outer side of the sliding block, an inserting block matched with the slots to be inserted is fixedly connected to the inner wall of the groove, a groove body communicated with the groove is formed in the bottom wall of the groove, a fixing ring matched with the groove body to slide is fixedly connected to the bottom of the sliding block, and a pushing assembly for pushing the fixing ring to move upwards is arranged in the shell.
