Abstract

The invention discloses an air inlet valve of an oil-free screw compressor. The air inlet valve comprises a valve cover, a valve body, a valve plate, a valve rod, an elastic mechanism, a valve seat and a silencer; the valve body is connected with the valve seat, the valve seat is provided with an oil-free compressor exhaust cavity, and the silencer and the oil-free compressor exhaust cavity are provided with a connecting channel; the first end of the valve rod is connected with the valve plate capable of controlling suction flow of the compressor, the second end of the valve rod is provided with a sealing mechanism, and a connector of the valve rod is close to the oil-free compressor exhaust cavity; the valve plate is arranged close to the valve cover and can be opened or closed under the driving of the valve rod; a hydraulic cavity is formed inside the valve body, and the sealing mechanism is arranged in the hydraulic cavity; in the hydraulic cavity, hydraulic oil can be injected into the first side of the sealing mechanism; and the elastic mechanism is arranged on the second side of the sealing mechanism. According to the air inlet valve of the oil-free screw compressor, the size of the air inlet valve the oil-free screw compressor can be effectively reduced, the structure of the air inlet valve of the oil-free screw compressor is simplified, and the stability of the valve during operation is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to an inlet valve of a screw compressor, in particular to an oil-free screw compressor and an inlet valve thereof. Background technique [0002] The function of the intake valve of the screw compressor is to reduce the load of the compressor during the start and stop stages by controlling the opening and closing of the intake valve during the loading and unloading process of the compressor, so as to avoid the instantaneous power of the motor when starting. cause an impact on the grid. The working process of its normally closed intake valve is to control the opening of the valve plate in the valve through the external force acting on the valve plate, so as to achieve the purpose of controlling the intake flow of the compressor. When the valve plate of the valve is working at any opening, there should be no surge, cavitation, etc. For oil-free screw compressors, in addition to sat...
