Embodiment
Be described in detail below in conjunction with accompanying drawing the utility model.
See Fig. 1 to Fig. 4, a kind of intake and exhaust pipe fitting for refrigeration compressor, there is the inner body 1 for hollow shape, described body 1 comprises the first breakthrough part 2 and the second breakthrough part 3 passed through for gas-liquid, the protrusion fixing part 4 for welding with compressor is provided with between described first breakthrough part 2 and the second breakthrough part 3, the outer end of described first breakthrough part 2 is also connected with the external connection portion 5 inserted for outside pipe arrangement, and described first breakthrough part 2, second breakthrough part 3, protrusion fixing part 4 and external connection portion 5 are one-body molded; This air inlet-outlet pipe is owing to having integrated protrusion fixing part 4, when mounted, can directly and refrigeration compressor be welded and fixed, decrease assembly process, simultaneously itself and refrigeration compressor be welded and fixed more reliable, it should be noted that: intake and exhaust pipe fitting described in the utility model can be applicable to the use of refrigerant at gaseous state, liquid simultaneously, that is, it can be arranged on refrigeration compressor as suction tude and the liquid output tube of refrigerant, in sum, these intake and exhaust pipe fitting have easy for installation, connect reliable advantage.
In the technical program, in order to make external pipe fitting better be connected with these intake and exhaust pipe fitting, the internal diameter D1 of external connection portion 5 is greater than the internal diameter D2 of the first breakthrough part 2, makes the internal connection of external connection portion 5 and the first breakthrough part 2 form grafting and limits platform 6; Further, the tip inside of described external connection portion 5 is provided with sealing recess, specifically, when connecting, external pipe fitting is inserted in the internal diameter D2 of external connection portion 5, under the effect of grafting restriction platform 6, then carry out sealing and fix, because described grafting restriction platform 6 is inclined-plane restriction, and its D1 is greater than D2, so grafting restriction platform 6 pairs of refrigerants can play drainage, thus effectively can prevent the leakage of refrigerant; With this simultaneously, external pipe fitting can insert in external connection portion 5 by a sheathed seal ring, thus seal ring is clamp-oned in sealing recess, thus better can realize seal action.
Wherein, the outer end of described second breakthrough part 3 is for be connected and sealed fixing with refrigeration compressor, and the outer end of described second breakthrough part 3 is also connected with seal holder part 7.
Because the size of the default connection mouth of refrigeration compressor is fixing, in order to improve versatility when these intake and exhaust pipe fitting connects, make it operate more easily when being sealedly connected and fixed, the external peripheral surface of described seal holder part 7 is inner concave arc surface 71.Like this, described seal holder part 7 is when being connected with refrigeration compressor, and described inner concave arc surface 71 can sheathed Sealing, thus is directly inserted in the default connection mouth of refrigeration compressor, realizes the reliability be tightly connected.
In the technical program, in order to reduce manufacture cost further, described body 1 is ferrous material.
In order to ensure that refrigerant flows smoothly in pipe fitting further, and consider in conjunction with current manufacturing process, the internal surface of described body 1 is the slippery inner surface seamlessly transitted, and the roughness Ra of its slippery inner surface is 5 μm ~ 10 μm;
This intake and exhaust pipe fitting in use, often needs to carry out cold and hot exchange, and its outside is when the contact of air, and other pipe fitting is more prone to get rusty relatively, and as further improvement, the outer surface of described body 1 has resin layer 8; Described resin layer 8 can adopt copper facing or electroplate other anti-rust metal, thus reaches the object in the working life extending these intake and exhaust pipe fitting.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
