Abstract

The invention relates to a slide valve, a screw compressor provided with the slide valve and a screw unit. The slide valve comprises a valve body, and a key slot and a balance groove formed in the valve body; the key slot is suffered from exhaust pressure generated by gas entering inside; and the balance groove and the key slot are spaced by a certain angle to balance the exhaust pressure. The slide valve is provided with the balance groove for balancing the exhaust pressure suffered by the key slot, so that the pressure suffered by the valve body can be reduced, the scratch of the valve body in axial movement due to butting of a machine body of the screw compressor under the effect of the exhaust pressure is prevented, the service life of the slide valve is prolonged, and the operation reliability of the slide valve is improved.

Description

technical field [0001] The invention relates to the field of power machinery, in particular to a slide valve, a screw compressor and a screw unit provided with the slide valve. Background technique [0002] Screw compressors are mainly used in the field of power machinery to drive various tools. Moreover, due to its high reliability, high degree of automation, good power balance and strong adaptability, screw compressors are more and more used in various industries, which brings great convenience to people's life and production. [0003] At present, the energy adjustment method of the screw compressor is mostly the slide valve adjustment. The slide valve is provided with a herringbone arc surface and an outer circular surface matched with the inner wall of the compressor body, and the two arc surfaces of the herringbone arc surface cooperate with the corresponding screw. As the slide valve moves relative to the body of the compressor, the keyway used to cooperate with the ...
