Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] see figure 1 , The compressor slide valve assembly according to an embodiment of the present invention includes a slide valve 100 , a slide valve rod 200 , a support plate 300 and a connecting rod 400 . Wherein, the slide valve 100 is connected with the slide valve rod 200 . The support plate 300 is arranged on the body of the compressor, and fits with the rear end of the sliding valve rod 200 with a gap (0.01-0.02 mm), so as to prop up the rear end of the sliding valve rod 200 . The connecting rod 400 is arranged on the body of the compressor, and cooperates with the front end of the sliding valve rod 200 with a clearance (0.01-0.02 mm) to prop up the front end of the sliding valve rod 200 . The support plate 3...

Abstract

The invention discloses a compressor slide valve assembly and a refrigeration screw compressor. The compressor slide valve assembly includes a slide valve, a slide valve rod, a support plate and a connecting rod; the support plate is arranged on the compressor body, in clearance fit with the rear end of the slide valve rod and used for supporting the rear end of the slide valve rod; the connecting rod is arranged on the compressor body, in clearance fit with the front end of the slide valve rod, and for supporting the front end of the sliding valve rod; and the slide valve is connected with the slide valve rod, and keeps a preset distance with the compressor body. The refrigeration screw compressor comprises the compressor slide valve assembly. The compressor slide valve assembly and refrigeration screw compressor of the invention reduce the contact area and friction between the slide valve and the compressor body, and can effectively solve the problems of compressor slide valve cavity abrasion and noise.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor slide valve assembly and a refrigeration screw compressor. Background technique [0002] Due to the structural limitation of the traditional slide valve upper structure compressor, the piston chamber and the slide valve chamber cannot be concentric. During the loading and unloading process, the oil pressure pushes the oil piston to reciprocate, and the slide valve is easily scratched against the body under its own gravity. Therefore, the traditional refrigeration screw compressor with the slide valve upper-mounted structure is prone to scratches or noise problems in the compressor slide valve cavity. Contents of the invention [0003] Based on this, it is necessary to address the defects and deficiencies of the prior art, and provide a compressor slide valve assembly and a refrigeration screw compressor, which avoid the slide valve from being supported by the arc surfac...
