The utility model has the following technical effect that：

Double-screw refrigeration compressor with Elastic Contact sealing of the present utility model, is formed using spring and contact diaphragm seal Elastic Contact is sealed, triangle of stopping a leak, and improves volumetric efficiency, improves the thermal performance of double-screw refrigeration compressor, is improved The operational efficiency of refrigerated air-conditioning system, energy saving consumption.

Brief description of the drawings

Fig. 1 is the schematic diagram of the double-screw refrigeration compressor that the utility model is sealed with Elastic Contact；

Fig. 2 is top view of the present utility model.

Specific embodiment

The utility model is described in detail below in conjunction with the drawings and specific embodiments

As illustrated in fig. 1 and 2, the double-screw refrigeration compressor with Elastic Contact sealing of the present utility model, including male rotor 1st, body 2, female rotor 3, contact diaphragm seal 4, spring 5, support 6, male rotor main shaft 8, vent connection 9, air-breathing bolt of cover 10, Air-breathing adapter 11, air-breathing side end cap 12, exhaust end cover bolt 13 and exhaust side end cap 14.

The bottom correspondence negative and positive rotor exhaust position of the exhaust side end cap 14 is provided with steam vent and is welded with vent connection 9 Connection, the position for corresponding to male rotor main shaft 8 offers the main bearing hole for running through, and correspond to the driven shaft of female rotor 3 is positioned against machine The side of body 2 offers the driven-shaft hole not run through, and the body 2 passes through exhaust end cover bolt 13 and gasket seal and exhaust side End cap 14 is tightly connected, and body 2 offers what is run through vertically near the negative and positive rotor cylinder-bore inwall intersection of steam vent side Spring 5 is placed in groove, groove, contact diaphragm seal 4 is consistent with cylinder-bore axial length, is axially inserted into groove, its width Side contacts with spring 5, its width opposite side under the elastic reaction of spring 5 with the peak contact of negative and positive rotor, contact Two thickness direction sides of diaphragm seal 4 relative can be slided with groove, and male rotor 1 and female rotor 3 are engaged and be axially inserted into placement In the cylinder-bore of body 2, support 6 is welded to connect with body 2, and the position of the corresponding negative and positive armature spindle of air-breathing side end cap 12 is provided with Bearing hole, correspondence negative and positive rotor suction position is provided with suction hole and is welded to connect with air-breathing adapter 11, by air-breathing bolt of cover 10 and gasket seal be tightly connected with body 2.
