The utility model provides an exhaust structure of a rotor compressor and a rotor compressor, belonging to the technical field of compressors. The exhaust structure includes an exhaust port, a valve plate, a seat ring and a valve seat. The seat ring is arranged on the valve seat and is arranged around the exhaust port. The valve plate is arranged above the exhaust port and can open or close the exhaust port. The seat ring is made of non-metallic materials. Because the seat ring in the exhaust structure is made of non-metallic material, the seat ring of non-metallic material is arranged on the valve seat, and the pressure during installation is small, unlike the metal seat ring in the prior art, which is forced through the valve seat and cannot be replaced, the exhaust structure of the rotor compressor provided by the utility model can replace the seat ring when the seat ring is scrapped, so as to reduce the scrapping of the exhaust structure Rate. At the same time, the exhaust structure is made of non-metallic materials, and the seal of seat ring and valve plate is changed from rigid seal to soft seal, so the sealing effect is better, and the service life of valve plate can be improved, and the noise during the operation of compressor can be reduced.

一种转子式压缩机的排气结构及转子式压缩机
本技术涉及转子式压缩机领域,特别涉及一种转子式压缩机的排气结构及转子式压缩机。
技术介绍
目前的转子式压缩机中的排气结构通常采用舌簧阀结构,舌簧阀结构通常如图1所示,其包括螺栓或铆钉1、挡板2、阀片3、座圈4和阀座5,其中的座圈4通常是由粉末冶金材料制成后压入并贯穿阀座5,或者,利用阀座5的铸铁材料将阀座5和座圈4直接铣削加工成一体的结构。现有的舌簧阀排气结构至少存在以下问题:座圈为金属材料制成,如果座圈报废,由于不能单独更换座圈,会导致整个舌簧阀排气结构及整个缸盖报废。
技术实现思路
本技术提供了一种转子式压缩机的排气结构及转子式压缩机,以降低排气结构的报废率。同时该排气结构采用非金属材料,座圈和阀片的密封由刚性密封变为软密封,密封效果更好,并且可以提高阀片的寿命、降低压缩机运转过程中的噪音。为实现上述目的,本技术提供了一种转子式压缩机的排气结构,所述排气结构包括排气口、阀片、座圈和阀座,所述座圈设于所述阀座上并环绕所述排气口设置,所述阀片设置于所述 ...
