Abstract

The invention discloses a clamping mechanism for a seal surface grinding unit of a valve, which comprises an operating handle, a first screw, a second screw, a synchronous interlocking member driving the first screw and the second screw to rotate simultaneously with the operating handle, as well as a first blocking member and a second blocking member which displace oppositely along the first screw and the second screw and used for clamping a valve flange; the second screw and the first screw have same structure, and are mutually parallel; a first central fixing seat is fixedly arranged in the middle of the first screw; and a second central fixing seat is fixedly arranged in the middle of the second screw. When in use, the clamping mechanism for the seal surface grinding unit of the valve can guarantee the grinding quality, reduce the maintenance workload, and low the maintenance cost by employing the structure.

Description

technical field [0001] The invention relates to a valve sealing surface grinding device, in particular to a clamping mechanism of the valve sealing surface grinding device. Background technique [0002] With the further deepening of my country's industrialization, various forms of valves such as safety valves, globe valves, and gate valves are widely used in chemical, boiler, and pressure vessel industries. Since the valve is in use, the sealing surface has been eroded by the medium used for a long time, washed away by gas and foreign matter in the fluid for a long time, and often worn by the switch. It will damage the flatness of the valve sealing surface, cause the valve to leak, and cause waste of raw materials and economic losses. Therefore, in order to avoid valve discarding and waste, it is necessary to use a valve sealing surface grinding device. At present, there is no clamping mechanism for such a valve sealing surface grinding device, which can ensure the grinding...
