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,...

Embodiment

[0028] A multifunctional self-adaptive ball valve grinding machine, its structure is as follows Figure 1-2 As shown, the grinding machine includes a grinding structure, a liquid inlet and outlet structure, and a control structure.

[0029] The grinding structure is composed of a grinding head motor 13, a cone head valve stem 12, a grinding head 14, a valve stem chuck 15, and a workbench 4. The ball valve 16 to be processed is set on the workbench 4. The grinding head motor 13, the grinding head 14. The valve stem chuck 15 and the conical valve stem 12 are connected sequentially from top to bottom, and the ball valve 16 of the ball valve to be processed is ground. The grinding head motor 13 is connected to the grinding head column 27 on the workbench 4, and drives the valve core of the ball valve 16 to rotate at a high speed through the valve stem chuck 15 to achieve matching grinding with the valve seat, improve the grinding quality and efficiency, and ensure the sealing of t...
