Grinding machine for grinding of ball valve ball body

Abstract

The invention relates to a grinding machine for grinding of a ball valve ball body. The grinding machine for grinding of the ball valve ball body is characterized in that the grinding machine for grinding of the ball valve ball body comprises a machine frame, a power supporting plate, a gear box, a driving motor, a tailstock supporting plate and a tailstock clamping mechanism; a ball body drivingshaft and a grinding power shaft are installed in the gear box; a telescopic shaft is connected to the end portion of the ball body driving shaft, a driving wheel is installed at the upper end portionof the grinding power shaft, a cantilever beam is arranged on the upper portion of a supporting sleeve, and a grinding shaft is installed at the end portion of the cantilever beam; a driven wheel isinstalled on the upper portion of the grinding shaft of the cantilever beam, and a transmission element is installed between the driving wheel and the driven wheel; and a suspension frame is installedat the lower end of the grinding shaft, a telescopic arm is installed on the suspension frame in a penetrating mode, a rocker is installed at the one end of the telescopic arm in the vertical direction in a penetrating mode, a grinding rack is connected to the lower end of the rocker, and a grinding tool of a valve seat sealing surface is arranged at the lower end of the grinding rack. The grinding machine for grinding of the ball valve ball body has the advantages that the conception is novel, the use is convenient, the machining efficiency and quality of the ball body are improved, good sealing performance is ensured after the grinding machine is matched with the valve seat, and the grinding difficulty of a ball body workpiece is reduced.

Description

technical field [0001] The invention belongs to the technical field of grinding and processing of ball valves, in particular to a grinding machine for grinding and processing of balls of ball valves. Background technique [0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The main feature of the ball valve is its compact structure, which is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. Suitable for frequent operation, quick and easy opening and closing. Fluid resistance is small. Simple structure, relatively small size, light weight and easy maintenance. The good sealing performance is not limited by the installation direction, and the flow direction of the medium can be arbitrary. As the p...

Problems solved by technology

The ball mills that can be purchased in the domestic market have a small diameter, and if you want to increase the diameter, the price will be more expensive

Imported ball mills are expensive and require high maintenance costs

If the traditional manual grinding method is adopted, the production efficiency is low and the operation labor intensity is relatively large
