Multifunctional self-adaption ball valve grinding miller

Abstract

The invention relates to a multifunctional self-adaption ball valve grinding miller. A ball valve core is driven by a valve rod chuck to rotate at a rotating speed according to the technological requirement by a grinding head motor, so that the match with a valve base for grinding is realized, the grinding quality and efficiency are increased and the sealing property of the valve is ensured; the grinding miller is matched with the ball valves in different sizes by adjusting the positions of a variable liquid outlet connecting port, a moveable liquid inlet connector and the center of the grinding head, so that the use scope of the grinding miller is expanded and the adaptivity is increased; a circulating pump is arranged, so that the cyclic utilization of the grinding liquid is realized, the cyclic utilization is green and environment-friendly and the production cost is lowered; a grinding structure composed of the grinding head motor, the grinding head, the valve rod chuck and the working rack can be used for match grinding and milling the other rotors, so that the universality is strong and the production efficiency is high; through a longitudinal workbench servo motor and a horizontal workbench servo motor and the adjustment for the positions of the working rack and the ball valve, the ball valve is clamped by an electric hydraulic cylinder, so that the working efficiency is increased and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a valve manufacturing equipment, in particular to a multifunctional self-adaptive ball valve grinder. Background technique [0002] The surface roughness, roundness and matching accuracy of the ball valve spool and the valve seat are one of the main factors affecting the valve seal. Although the size, surface roughness and shape accuracy of the turning and grinding ball can be processed to the required accuracy, when the ball and the valve seat are metal seals, due to the shape of the contact surface between the ball shape and the valve seat and the installation error, the ball and the valve There is a contact error on the sealing surface of the seat. When the contact error reaches a certain value, the sealing surface will leak. Therefore, it is necessary to cooperate with the grinding of the ball and the sealing surface of the valve seat. The traditional manual grinding method is labor-intensive, low in production efficiency,...

Although the size, surface roughness and shape accuracy of the turning and grinding ball can be processed to the required accuracy, when the ball and the valve seat are metal seals, due to the shape of the contact surface between the ball shape and the valve seat and the installation error, the ball and the valve There is a contact error on the sealing surface of the seat. When the contact error reaches a certain value, the sealing surface will leak. Therefore, it is necessary to cooperate with the grinding of the ball and the sealing surface of the valve seat.

The traditional manual grinding method is labor-intensive, low production efficiency, and difficult to guarantee quality

[0003] The Chinese patent No. ZL200910172519.7 discloses a spherical grinding machine for double eccentric hemispherical valve discs. A frame, a motor, a rotating spindle for carrying workpieces, tooling, etc. are arranged on the machine base. The grinding machine is adjusted by the angle adjustment frame so that The grinding tool rotates at a constant speed on the disc of the hemispherical valve, so that it can form intersecting mesh tracks to achieve an ideal spherical grinding surface. However, this patent cannot be processed according to ball valves of different sizes, and the scope of application is narrow.
