Background technology
The widely used central jet orifice-plate type distributor of Refrigeration ＆ Air-Conditioning industry at present, as shown in figure 1, its central jet
Fixed form of the orifice plate in distributor be substantially：Jet orifice plate is put into distributor afterbody counterbore, then by a change
In the big end insertion distributor afterbody counterbore of footpath transition conduit and it is welded and fixed.Major defect in this way is：（1）Need to increase
Add one of welding sequence, this has been correspondingly increased the risk of leakage；（2）Due to adding reducing transition conduit this part, make
The axial dimension for obtaining whole distributor significantly increases.
Utility model content
Deficiency of the purpose of this utility model aiming at prior art, there is provided one kind fixes jet orifice using spinning process
The distributor of plate, reach the purpose for eliminating welding risk of leakage and reducing distributor axial dimension.
The utility model adopts the following technical scheme that：
The distributor of fixed jet orifice plate, including main body, described main body have entrance point and the port of export, the main body
Port of export inner chamber is provided with jet orifice plate, and described jet aperture plate center is provided with inner chamber；The middle part of the main body has tapering transition
Section, the port of export external diameter of main body are more than entrance point external diameter.
As further improving and supplementing to such scheme, the utility model also includes following additional technical feature：
The material of the jet orifice plate is stainless steel or copper.
The material of the main body is copper or aluminium.
The main body also includes hybrid chamber, and the first inner chamber of the entrance point is connected by hybrid chamber and the jet orifice plate
It is logical；The diameter of the hybrid chamber is more than the diameter of the first inner chamber.
The entrance point of the main body is provided with to position the first positioning hole of inlet tube, and first in the entrance point
Interior intracavitary, first positioning hole and the first inner chamber coaxial line, the diameter of first positioning hole are less than in described first
The diameter of chamber, positioning are convenient.
The port of export of the main body is provided with to position the second positioning hole of outlet, and second in the port of export
Interior intracavitary, second positioning hole and the second inner chamber coaxial line, the diameter of second positioning hole are less than in described second
The diameter of chamber, positioning are convenient.
It can reach following beneficial effect using the utility model：Without welding, let out so as to eliminate caused by welding
Leak out danger；The axial dimension of distributor is reduced, makes its structure compacter, reduces production cost.
Brief description of the drawings
Fig. 1 is the jet orifice plate dispensing arrangement schematic diagram of prior art.
Fig. 2 is jet orifice plate dispensing arrangement schematic diagram of the present utility model.
Fig. 3 is that the utility model does not carry out the structural representation before spinning.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Fig. 2 the utility model is the distributor of fixed jet orifice plate.
The distributor of fixation jet orifice plate described in the present embodiment, including main body 1, preferably, the material of main body 1 is copper
Or aluminium.Described main body 1 has entrance point 11 and the port of export 12, and the inner chamber of the port of export 12 of the main body 1 is provided with jet orifice plate 2,
The material of jet orifice plate 2 is stainless steel or copper, and the center of jet orifice plate 2 is provided with inner chamber 21；The middle part of the main body 1 has taper
Changeover portion 13, the external diameter of the port of export 12 of main body 1 are more than the external diameter of entrance point 11.
As shown in figure 3, first jet orifice plate 2 is put into the distributor body 1 of greenware condition, then using spinning process pair
The afterbody of distributor body 1 carries out undergauge processing, so as to which jet orifice plate 2 is fixed into the pre-determined bit being encapsulated in distributor body 1
Put.
The main body 1 also includes hybrid chamber 16, and the first inner chamber 14 of the entrance point passes through hybrid chamber 16 and the jet
Orifice plate 2 connects；The diameter of the hybrid chamber 16 is more than the diameter of the first inner chamber 14.
Further, the entrance point 11 of the main body 1 is provided with to position the first positioning hole 15 of inlet tube, in institute
State in the first inner chamber 14 of entrance point 11, first positioning hole 15 and the coaxial line of first inner chamber 14, first positioning
The diameter in hole 15 is less than the diameter of the first inner chamber 14, and positioning is simple and convenient.
Further, the port of export 12 of the main body 1 is provided with to position the second positioning hole 18 of outlet, is in
In the second inner chamber 17 of the port of export 12, second positioning hole 18 and the coaxial line of second inner chamber 17, described second is fixed
The diameter in position hole 18 is less than the diameter of the second inner chamber 17, and positioning is simple and convenient.
