The specific embodiment
Now the preferred embodiments of the present invention are carried out concrete description, the example of these embodiment is recorded in the accompanying drawing.
Fig. 2 is the cutaway view that the closed compressor of gas-liquid separator of the present invention is housed.
Closed compressor of the present invention comprises: the seal casinghousing 2 with constant space; A side that is loaded on housing 2 is used for producing the driver element 4 of revolving force; The opposite side that is loaded on housing 2 comes the compression unit 6 of compressed refrigerant by the driving force of driver element 4 generations; And be connected to housing 2 and be used for preventing that liquid refrigerant from entering into the gas-liquid separator 8 of housing 2 by managing 10.
As shown in Figure 3, gas-liquid separator 8 comprises: have the housing 10 that constant space is used for guiding cold-producing medium; The top side that is connected in housing 10 hermetically is used for guiding cold-producing medium to enter into suction line 12 in the housing 10; And being inserted into discharge pipe 14 in the housing 10 from the bottom side of housing 10 with constant length, this discharge pipe 14 is connected on the compressor housing 2, with will be housing 10 in the vaporized gas cold-producing medium introducing compressor housing 2.
Equally, screen cloth 16 is installed in the housing 10, is used for filtering the impurity in the cold-producing medium that is drawn into suction line 12, thereby stops the impurity in the cold-producing medium to enter in the compressor.
Housing 10 can be categorized as tubular monolithic devices made in one piece and separated into two parts and then the divergence type that is welded to each other.The patchhole 18 that is used to insert suction line 12 is formed at the top side of housing 10, and the patchhole 20 that is used to insert discharge pipe 14 is formed at its bottom side.Housing 10 preferably uses iron material to make.
Suction line 12 and discharge pipe 14 are made by iron material respectively, and by welded seal be connected to the top side and the bottom side of housing 10.
Suction line 12 is inserted in the patchhole 18 that is formed at housing 10 top sides, and along the circumferential direction welds between the external peripheral surface of the end portion of patchhole 18 and suction line 12, thereby forms first welding portion 22.
Discharge pipe 14 is inserted in the patchhole 20 that is formed at housing 10 bottom sides with constant length, and second welding portion 24 is formed between the external peripheral surface of the end of patchhole 20 and discharge pipe 14.
Just, thus form first welding portion 22 and second welding portion 24 by using phosphor bronze to weld as welding material.
By using phosphor bronze, between discharge pipe 14 and compressor housing 2, carry out brazing.At this moment, be inserted between the welding portion of the welding portion of discharge pipe 14 and housing 2 filling metal 26.
Filling metal 26 is preferably made by copper product.
The assembling of gas-liquid separator of the present invention step is as described below finished.At first, suction line 12 is inserted in the patchhole 18 that is formed at housing 10 top sides, and discharge pipe 14 is inserted in the patchhole 20 that is formed at housing 10 bottom sides.Then, welding with phosphor bronze between suction line 12 and the housing 10 and between discharge pipe and the housing 10 simultaneously.
Owing between housing 10 and discharge pipe 14, use phosphor bronze to weld, thereby the intensity of welding is strengthened.Therefore, just can not need to be used for supporting the additional tube stay that is inserted into the discharge pipe 14 in the housing 10, thereby reduce the quantity of parts.
Fig. 4 is the cutaway view of the gas-liquid separator of another one embodiment of the present invention.
In the gas-liquid separator of this another embodiment, housing 10 and suction line 12 weld by copper hard solder, and housing 10 and discharge pipe 14 also weld by copper hard solder.
Just, suction line 12 is inserted in the patchhole 18 that is formed at housing 10 top sides, welds between suction line 12 and patchhole 18 by the method for copper hard solder welding then, thereby forms first welding portion 30.Equally, discharge pipe 14 is inserted in the patchhole 20 that is formed at housing 10 bottom sides, welds between discharge pipe 14 and patchhole 20 by the method for copper hard solder welding then, thereby forms second welding portion 32.
Here, housing 10, suction line 12 and discharge pipe 14 are made by iron material respectively.
Between discharge pipe 14 and compressor housing 2, carry out brazing by using phosphor bronze or copper hard solder.At this moment, the filling metal 26 of copper product is inserted between the welding portion of the welding portion of discharge pipe 14 and housing 2.
In the gas-liquid separator of closed compressor of the present invention, thereby suction line, discharge pipe and housing are made by iron material respectively and are reduced production costs.Equally, owing to use phosphor bronze or copper hard solder welding between suction line and the housing and between discharge pipe and the housing, welding portion can be avoided being vibrated and other effect and damaging, and weld strength has also obtained reinforcement.Therefore, just can not need to be used for supporting the additional tube stay of discharge pipe, thereby reduce the quantity of parts.
And the performance of welding can improve, and the leakage of welding portion can be avoided, and production efficiency also can be improved.
Because the present invention can implement in the multiple mode that does not break away from its invention essence, thereby will be appreciated that, except as otherwise noted, the aforesaid any details of can't help embodiment described above limits, and the just essential structure in defined scope of appended claim and aim, and all fall in the claim scope or its equivalent scope is interior distortion and change all should be included by appended claim.
