Multi-size valve seat grinding table

Abstract

The invention relates to a multi-size valve seat grinding table, which includes a base, an installation cavity is arranged in the middle of the base, and an upper chamber and a lower chamber are formed in the middle of the installation cavity by isolation rings, and the lower end of the lower chamber is threaded through the bottom plate and the base. The connection seals the lower chamber, the top of the base plate is fixed with a rotating motor through a set screw, the rotating shaft of the rotating motor is vertically arranged, the upper end surface of the base is located on both sides of the upper chamber and two clamping devices are symmetrically arranged, and the upper chamber A rotating tray and a fixed plate are arranged sequentially from bottom to top, an end face grinding round table is arranged in the upper middle of the fixing plate, an inclined grinding round table is arranged on the upper end of the end face grinding round table, and the rotating shaft is fixedly connected with the lower end of the rotating tray. The grinding round table of the present invention can move horizontally under the driving of the card seat, and change the grinding radius, so that it can be applied to grinding the inclined sealing surfaces of valve seats with different calibers, and has a wider application range and strong practicability.

Description

technical field [0001] The invention relates to a grinding device, which belongs to the technical field of mechanical processing. More specifically, the invention relates to a multi-size valve seat grinding table. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Valves generally include a valve body, a sealing cover, a valve seat, a valve core (disc) and a valve stem, which constitute a fluid-tight structure as a whole. Among them, the valve seat is a removable surface part in the v...
