Abstract

The invention provides a grinding device and a grinding method of an oil well pump valve seat. The grinding device is composed of two large parts, namely an upper grinding part and a lower grinding part, wherein the upper grinding part is internally provided with a spring; an upper grinding head and a valve seat are mounted in a valve seat clamping sleeve. The grinding method comprises the following steps: the upper grinding part and the lower grinding part are connected with a motor to drive the valve seat to move up and down; grinding pressure is applied between the valve seat and a lower grinding head of the lower grinding part by using the spring, and the valve seat is ground. By adopting the grinding device and the grinding method, at least two valve seats can be ground in one step, and each valve seat is independently controlled by one set of the independent valve seat grinding device. The grinding efficiency of the valve seat is improved, the labor load of an operator is reduced, and the grinding yield of the valve seat is high; the grinding device and the grinding method are particularly suitable for a petroleum drilling and production industry.

Description

technical field [0001] The invention belongs to a grinding device and a grinding method thereof, in particular to a grinding device and a grinding method of a valve seat of an oil well pump used in petroleum drilling. Background technique [0002] For oil well pumps used in oil drilling, the valve seat needs to be ground by a grinding device to form a sealing surface in order to meet the sealing performance requirements. [0003] Existing valve seat grinding device is made up of two big parts of upper grinding part and lower grinding part. The valve seat in the upper grinding part is driven by the motor, clamped in the horizontal direction, and only one valve seat can be clamped at a time, and the valve seat only rotates; the lower grinding part is manually operated, which can either rotate or swing, and at the same time The grinding pressure is applied, that is, the grinding pressure applied to the valve seat is implemented by the lower grinding part. Because the grinding...
