Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, specifically a grinding device for valve manufacturing. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Valves are also classified according to their materials, such as cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard customized valves.

[0003] Application number CN202222636357.1 discloses a grinding device for valve manufacturing. This utility model relates to a grinding device for valve manufacturing, including a base plate, a frame bolted to the top of the base plate, a cylinder bolted to the top of the inner wall of the frame, a lifting plate bolted to the lower end of the cylinder, and connecting plates bolted to both sides of the bottom of the lifting plate. A protective cover is rotatably connected between the two connecting plates. A controller is used to start a telescopic rod to drive the clamping plate to fix the valve. A first motor is started to drive the grinding disc to rotate, and at the same time, the cylinder is started to drive the lifting plate to move vertically. The lifting plate drives the grinding disc at the bottom to move downward, and a second motor is started to drive the protective cover to rotate and adjust, thereby enabling the grinding disc to be rotated and adjusted for use. A blower drives air through the air inlet groove and the filter plate, and guides the airflow into the exhaust pipe. Pulling the handle pipe moves the exhaust pipe, and the elastic hose in the exhaust pipe is stretched. The airflow is finally discharged from the lower end of the handle pipe, and the airflow is used to clean the dust generated by grinding the valve surface.

[0004] In a typical valve manufacturing grinding device, a blower is used to clean the valve between grinding operations. However, this device generates rust dust during grinding. Because the device does not remove the rust dust, workers inhale some of the dust, posing a safety hazard. Therefore, it is necessary to design a structure to remove the rust dust, reduce worker inhalation, and protect worker safety. Thus, we propose a valve manufacturing grinding device to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] Furthermore, there are four B rotary motors.

[0012] Furthermore, the fixing plate and the protective cover are fixedly connected.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model uses a ventilation assembly to start a rotary motor A, which drives the rotating shaft to rotate, thereby causing the rotating shaft to drive the grinding disc to rotate. Start a hydraulic motor B, which controls the hydraulic telescopic rod B to move downward. The hydraulic telescopic rod B drives the connecting plate to move downward, and the connecting plate drives the U-shaped plate to move downward, thereby driving the grinding disc to move downward, achieving the function of grinding the valve body. Start a rotary motor B, which drives a fan A to rotate, drawing air in through the air inlet to blow away the rust dust that has been ground. At the same time, start a rotary motor C, which drives a fan B to rotate, discharging the rust dust that has been ground through the dust outlet pipe, thereby achieving the purpose of protecting the safety of the workers and solving the problem of rust dust causing harm to workers when grinding valves.

[0015] (2) In this utility model, by using a grinding assembly, the valve is placed between two clamping blocks. The A hydraulic motor is started, and the A hydraulic motor controls the A hydraulic telescopic rod to move to the middle. The A hydraulic telescopic rod drives the clamping blocks to move to the middle to fix the valve and close the transparent plate. Then the A rotary motor is started, and the A rotary motor drives the rotating shaft to rotate, which in turn drives the grinding disc to rotate. The B hydraulic motor is started, and the B hydraulic motor controls the B hydraulic telescopic rod to move downward. The B hydraulic telescopic rod drives the connecting plate to move downward, and the connecting plate drives the U-shaped plate to move downward, which in turn drives the grinding disc to move downward, thereby achieving the effect of grinding the valve body.
