The technical scheme in the invention for solving the technical problem is: a kind of suction valve of novel scroll formula air compressor, comprise the suction port valve body of sleeve shape and the air outlet valve body of sleeve shape, described suction port valve body is placed in the valve body of described air outlet, the upper end of described suction port valve body is a suction port, the lower end of described air outlet valve body is the air outlet, the inner chamber UNICOM of the inner chamber of described suction port valve body and described air outlet valve body, be provided with seal arrangement in the inner chamber of described suction port valve body, the madial wall of the bottom of described air outlet valve body is provided with internal thread.
Further, the outer side wall of the bottom of described air outlet valve body is hexagon.
Further, the outer side wall on the top of described air outlet valve body is cylindrical.
Further, offer the linked hole of the inner chamber of the inner chamber of the described suction port valve body of UNICOM and air outlet valve body on the sidewall of described suction port valve body; The inwall of the suction port valve body of described linked hole top is provided with the inwardly protruded step back-up ring of a circle, there is the sealing gasket of the inner chamber of salable described suction port valve body the below of described step back-up ring, there is gasket base the below of described sealing gasket, and described sealing gasket is adjacent on described gasket base; One screw base penetrates described sealing gasket from top to bottom, a lock screw by down from pass described gasket base and penetrate in the described screw base; Be provided with a circle back-up ring in the suction port valve body of described gasket base below, described back-up ring is provided with valve seat, is connected by stage clip between described valve seat and the described gasket base.
Further, the madial wall on the top of described suction port valve body is provided with internal thread.
The utility model from the suction port air inlet, is given vent to anger from the air outlet through suction port valve body, air outlet valve body in use at last, and the outlet side is adopted and is threaded, and inlet end also adopts and is threaded.
The beneficial effects of the utility model are: 1. the form that is connected with inlet end of outlet side adopts the complete machine layout that is threaded and is beneficial to compressor, saves installing space, is convenient in the future maintenance and maintenance.2. the outer side wall of the bottom of air outlet valve body is hexagon, and remaining part is cylindrical, and this not only makes the profile of suction valve more attractive in appearance, and has reduced the volume of suction valve greatly, has reduced the cost of manufactured materials.3。Adopt sealing gasket to seal, make the sealability of valve stable, reliable.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of suction valve of novel scroll formula air compressor, comprise the suction port valve body 1 of sleeve shape and the air outlet valve body 2 of sleeve shape, described suction port valve body is placed in the described air outlet valve body 2, the upper end of described suction port valve body 1 is a suction port 3, the lower end of described air outlet valve body 2 is air outlet 4, the inner chamber UNICOM of the inner chamber of described suction port valve body 1 and described air outlet valve body 2: the linked hole 5 that offers the inner chamber of the inner chamber of the described suction port valve body 1 of UNICOM and air outlet valve body 2 on the sidewall of described suction port valve body 1.Be provided with seal arrangement in the inner chamber of described suction port valve body 1, the madial wall of the bottom of described air outlet valve body 2 is provided with internal thread 6, and the madial wall on the top of described suction port valve body 1 is provided with internal thread 15.
In the present embodiment, the outer side wall of the bottom of described air outlet valve body 2 is hexagon, and the outer side wall on the top of described air outlet valve body 2 is cylindrical.
In the present embodiment, the specific constructive form of seal arrangement is: the inwall of the suction port valve body of described linked hole 5 tops is provided with the inwardly protruded step back-up ring 7 of a circle, there is the sealing gasket 8 of the inner chamber of salable described suction port valve body the below of described step back-up ring 7, and sealing gasket 8 can be adjacent on step back-up ring 7.There is gasket base 9 below of described sealing gasket 8, and described sealing gasket 8 is adjacent on described gasket base 9; One screw base 10 penetrate from top to bottom described sealing gasket 8, one lock screws 11 by down from pass described gasket base 9 and penetrate in the described screw base 10; Be provided with a circle back-up ring 12 in the suction port valve body of described gasket base 9 belows, described back-up ring 12 is provided with valve seat 13, is connected by stage clip 14 between described valve seat 13 and the described gasket base 9.
