Abstract

The invention discloses a diaphragm compressor follow-up valve and a using method thereof, and belongs to the technical field of diaphragm compressor structures. The diaphragm compressor follow-up valve comprises a valve body and a valve deck which are fixedly connected. A work cavity is formed between the valve body and the valve deck, and a valve needle is arranged in the work cavity. The valvebody is provided with an oil cavity connecting end; the oil cavity connecting end communicates with an oil channel, and the oil channel is in separable sealed contact with the valve needle; the valvedeck is provided with an exhaust pressure connecting end; the exhaust pressure connecting end communicates with an air channel, and a piston rod is slidably arranged in the air channel and fixedly connected with a spring seat; and the outer side of the valve needle is sleeved with a spring, and the spring is positioned between an oil baffle block and the spring seat. The device adopts a valve needle structure, so that the pressure bearing area is small, the overall size of the follow-up valve is correspondingly reduced, the weight is light, and the burden on a follow-up valve connecting piececan be reduced at the same time on the occasion with large vibration. The oil discharge pressure is also only related to the exhaust pressure of a compressor and the pre-compression amount of the spring, the oil discharge pressure can be adjusted by replacing the spring or adding a spring adjusting pad, the use is flexible, and the controllability is also greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of diaphragm compressor structures, in particular to a diaphragm compressor follow-up valve and a method for using the same. Background technique [0002] At present, the basic principle of the diaphragm compressor is that the motor drives the crankshaft to reciprocate the piston through the cross head, and the piston passes through the hydraulic oil in the oil chamber to deform the diaphragm under pressure and change the volume of the air chamber above the diaphragm to achieve gas compression. During the operation of the diaphragm compressor, the piston cannot ensure that the hydraulic oil in the oil chamber does not leak, so it is necessary to replenish oil into the oil chamber during the suction process of each reciprocating cycle, and at the same time, it is also necessary to complete the compression in each reciprocating cycle , drain excess oil. The function of the follow-up valve is to discharge the...
