Single-head hydraulic valve grinding machine control system

Abstract

The invention discloses a control system of a single-head hydraulic valve grinder, and belongs to the field of grinders, during coarse grinding of a grinder body, an extrusion ball enables rotation to be centrifugally influenced, a piston is pushed to extrude air in an extrusion cylinder to be blown into an elastic magnetic insulation bag body, the air is expanded to drive magnetic insulation powder to be dispersed, magnetic shielding of a magnetic ball is cancelled, and the magnetic insulation powder is dispersed. A magnet block attracts a magnetic ball and a moving frame to move downwards, a movable rod drives a dust blocking cover to move downwards, the dust blocking cover is matched with a bonding layer to block and adhere splashed chippings, meanwhile, the dust blocking cover rotates along with a grinding machine body, surrounding air flows, the pressure intensity becomes small, negative pressure is generated nearby the dust blocking cover, and the dust blocking cover is prevented from splashing. The chips are adsorbed to the bonding layer through negative pressure adsorption, the influence of chip splashing is reduced, the friction roller moves along with the movable rod and generates static electricity on the fluff layer in a rolling friction mode, the chips splashed to the through opening are adsorbed to the superfine fiber layer, the chips are not prone to entering the fixing frame, and workers can conveniently clean the chips.

Description

technical field [0001] The invention relates to the field of grinding machines, and more specifically relates to a single-head hydraulic valve grinding machine control system. Background technique [0002] The valve is the most commonly used pipeline control part, and its sealing performance is particularly important. The main factors affecting the sealing performance of the valve are the material of the seal and the surface accuracy of the valve. In the existing technology, people use a hydraulic valve grinder to grind the valve surface. Grinding treatment makes the surface precision of the valve more perfect. The hydraulic valve grinding machine clamps the valve parts through the hydraulic mechanism and performs grinding processing on them. The operation is simple and it is widely used on the sealing surface of valve seats such as gate valves, globe valves and check valves. And gate sealing surface grinding and other fields. [0003] In the prior art, during the coarse gr...

Problems solved by technology

[0003] In the prior art, during the rough grinding process of the valve parts, the hydraulic valve grinder, due to its rapid rotation and grinding, makes the debris generated during the grinding process splash outward, which is not conducive to the cleaning of the staff, and will also affect the environment.
