Abstract

The invention provides a petroleum and petrochemical valve with a buffer structure, and relates to the field of valve buffering. The petroleum and petrochemical valve with the buffer structure comprises a valve body, a main valve plate, an auxiliary valve plate assembly, side buffering support pieces, a locking piece and a bottom buffering support piece. The petroleum and petrochemical valve withthe buffer structure has the beneficial effects that the petroleum and petrochemical valve is suitable for being placed in a notch or a groove to work and can meet the work requirements for differentdegrees of flow regulation. The main valve plate is connected in the valve body in a sealed and matched mode, the auxiliary valve plate assembly is connected to the main valve plate in a matched mode,the side buffering support pieces are arranged on the side faces of the valve body, the locking piece is arranged on the valve body, the side buffering support pieces drive the locking piece to lockthe main valve plate and the auxiliary valve plate assembly, and the bottom buffering support piece is arranged at the lower end of the valve body.

Description

technical field [0001] The invention relates to the field of valve buffering, in particular to a petroleum and petrochemical valve with a buffering structure. Background technique [0002] The patent number is CN201810721022.5 buffer valve structure, the invention relates to a buffer valve structure, including a valve body, a valve core and a valve seat are arranged in the valve body, an arc-shaped baffle is arranged in the valve seat, and the arc-shaped A leak hole and a fixing plate are arranged on the baffle, a guide hole is arranged on the fixing plate, a guide rod is inserted in the guide hole, one end of the guide rod is connected to the fixing plate through a compression spring, and the other end is connected to a Curved cover corresponding to leak hole. Under the action of the arc-shaped baffle and the arc-shaped cover, it plays a buffering role for the high-pressure liquid, preventing the high-pressure liquid at the liquid inlet of the valve body from directly impa...
