Embodiment Construction
[0023] The present invention will be further described below with specific embodiment, see figure 1 — Figure 12 :
[0024] An air compressor stop and start unloading device based on shrapnel opening and closing, suitable for an air compressor system composed of compressor 1, air tank 2, check valve 3, exhaust pipe 4 and other components (see figure 1 ), wherein the task of the compressor 1 is to compress the air working medium to increase its pressure, the task of the gas tank 2 is to store the compressed high-pressure gas, and the function of the check valve 3 is to prevent the high-pressure gas in the gas tank 2 from flowing back to the In the compressor 1, the task of the exhaust pipe 4 is to transport the high-pressure gas discharged from the compressor 1 to the gas tank 2; here, the exhaust pipe 4 refers to the pipe connecting the compressor 1 to the check valve 3 The check valve 3 is actually a one-way valve, the gas can only enter the gas tank 2 from the exhaust pipe...

The invention belongs to the technical field of compressors and relates to a spring-piece-based starting and stopping air compressor starting and stopping unloading device. The spring-piece-based starting and stopping air compressor starting and stopping unloading device is characterized in that sheet-shaped reed valves as well as release holes corresponding to the reed valves are arranged on an exhaust pipe between an exhaust valve and a gas cylinder check valve of a compressor and / or inside an exhaust cavity of the compressor, wherein the reed valves obtain certain elasticity and control opening and closing of the release holes; when being opened, the release holes communicate the inside of the exhaust pipe and the inside of the exhaust cavity with the external atmosphere or the air inlet cavity of the compressor; when the release holes are closed, the inside of the exhaust pipe and the inside of the exhaust cavity cannot communicated with the external atmosphere or the air inlet cavity of the compressor via the release holes. The spring-piece-based starting and stopping air compressor starting and stopping unloading device can exhaust high-pressure gas inside the exhaust pipe timely when the compressor stops working and close the release holes in a time-delayed mode when the compressor is restarted, thereby achieving stopping and starting unloading and facilitating normal start of the compressor.
Description
technical field [0001] The invention belongs to the technical field of compressors, and relates to an air compressor stop and start unloading device, in particular to an auxiliary starting device for stop unloading and start unloading that helps a compressor start smoothly and operate normally. Background technique [0002] The existing air compressor system is generally composed of a compressor, an air tank, pipelines and various control valves. The task of the compressor is to compress the air working medium to increase its pressure. The task of the air tank is to store the compressed high pressure The role of gas, pipelines and control valves is to transport the high-pressure gas discharged from the compressor to the gas tank and prevent the gas in the tank from backflowing back to the compressor. The control valve that prevents the high-pressure gas in the tank from flowing back into the compressor is called a backstop The valve is connected with a pipeline between the c...
