Workbench for grinding of valve seat

Abstract

The invention relates to a workbench for grinding of a valve seat. The workbench comprises a base. A mounting cavity is formed in the middle of the base. The middle of the mounting cavity is partitioned into an upper cavity body and a lower cavity body through a partition ring. The lower end of the lower cavity body is in threaded connection with the base through a bottom plate so that the lower cavity body can be sealed. A rotary motor is fixed to the upper end of the bottom plate through a fixing screw. A rotary shaft of the rotary motor is vertically arranged. Two clamping devices are symmetrically arranged at the positions, located on the two sides of the upper cavity body, of the upper end face of the base. The upper cavity body is sequentially provided with a rotary tray and a fixingplate from bottom to top. An end face grinding circular truncated cone is arranged in the middle of the upper end of the fixing plate. A slope grinding circular truncated cone is arranged at the upper end of the end face grinding circular truncated cone. The rotary shaft is fixedly connected with the lower end of the rotary tray. The workbench is simple in structure and small in size, a person can simultaneously operate a plurality of workbenches for grinding, the cost and energy consumption are low, in addition, the valve seat is clamped stably, uniform-velocity grinding of the valve seat can be ensured during grinding, thus, grinding is more precise, the grinding effect is good, and the precision is high.

Description

technical field [0001] The invention relates to a grinding device and belongs to the technical field of mechanical processing. More specifically, the invention relates to a workbench for grinding a valve seat. 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 valve...
