Abstract

The invention discloses a valve sealing surface grinding miller used for grinding a workpiece. The valve sealing surface grinding miller comprises a rack, a motor vertically mounted on the rack, and a feed mechanism mounted at the top part of the rack. The feed mechanism can move left and right as well as up and down; the grinding miler further comprises a main shaft connected with an output shaft of the motor, a grinding disc horizontally arranged on the main shaft, and a drive component fixed on the feed mechanism and used for regulating the space position of the drive component through the feed mechanism. The drive component comprises a drive motor, and a chuck connected with an output shaft of the drive motor. The valve sealing surface grinding miller can realize multiple functions, and can grind a sealing surface of a valve plate or a valve clack as well as a sealing surface of a valve seat in a valve body. The grinding precision is high, and the grinding movement, the grinding speed and the grinding force are more reasonable.

Description

technical field [0001] The invention relates to the field of sealing surface processing, in particular to a valve sealing surface grinder. Background technique [0002] The gate valve is a valve with gate as the opening and closing part. Because of its small flow resistance and simple and convenient operation, it is widely used in the installation and use of petroleum, chemical, and water supply pipelines. The sealing of the gate valve is through the contact of the sealing surface between the gate or the valve disc, the valve plate and the valve seat, and the sealing is achieved by the specific pressure formed by the medium pressure or the pressure input by the operating mechanism. [0003] Due to the low efficiency of manual grinding of the disc, valve plate, and gate, it is difficult to control the grinding movement, grinding speed, and grinding force. Leakage occurs at the valve seal. Contents of the invention [0004] The object of the present invention is to provide...
