Description
Technical field
The utility model relates to a kind of technology device that is used for air-conditioning internal machine manufacturing and installation process, the inflation pressurize when being used in particular for the air-conditioning internal machine test.
Background technique
Air conditioner needs the sealability of its refrigerant pipe is tested repeatedly in manufacture process.Be in the refrigerant pipe of interior machine, to charge into the nitrogen leak detection earlier, charge into helium leak check and charge into refrigeration agent at last to carry out gas welding and seal leak detection at present to the test mode of the interior machine (indoor set) of split-type air conditioner; If all qualified then product is qualified; No matter which link finds that gas leakage is arranged to said process, and the release of then need exitting is tested after repairing pipeline again.
Chinese patent (patent No. 200620109037.9) discloses a kind of air-conditioning internal machine inflation pressurize plastic valve, it in the shell of this valve an inner cylinder body, being equipped with in the inner cylinder body can be at the spool that slides along the housing axis direction, be shaped on some grooves that are beneficial to gas communication on the spool, in the inner chamber of the inflation inlet of spool rubber stopper is housed, this rubber stopper and inner cylinder body end form the valve port of unlatching or throttle down; The potential energy that spool also is subjected to a spring applied pressure to have close port.Adopt this valve not only can save working procedures and the tooling device and the equipment of original backwardness, and testing efficiency significantly improves, testing cost is able to remarkable reduction; Also effectively guarantee the healthy of staff, reduced pollution of atmosphere.
Yet the valve port of this valve is to cooperate formation between the rubber stopper of tapered end and inner chamber end of spool, thereby surface friction drag need apply certain external force and overcome valve port and open the time; In addition, the structure of whole valve also remains further to be simplified.
The model utility content
The purpose of this utility model is to overcome the problems referred to above that exist in the background technique, and a kind of improvement of air-conditioning internal machine gas charging valve is provided, and this device should have the original state valve port to be opened, the characteristics that inflation back valve port is closed, and high working efficiency, and using effect is good.
The technological scheme that the utility model proposes is: the air-conditioning internal machine gas charging valve, comprise a cylindrical case, be shaped on the internal thread that can be connected in the interface of shell left end with the air-conditioning internal machine refrigerant pipe, a clamping sleeve is fixed at the middle part of shell inner cavity, be shaped on the passage that several are beneficial to the inner chamber inner air flow on the clamping sleeve, other has a spool to be set on the axis hole at this clamping sleeve center slidably, the spool right-hand member cooperates with the inwall of shell inflation inlet one end form to be opened or the valve port of throttle down, and other has one to be positioned spring energized in the shell inner cavity and to make spool have the potential energy of close port in spool; Described spool right-hand member is equipped with an end-face seal ring, and the inwall of shell inflation inlet one end is then made the tubular port, cooperates between end-face seal ring and the tubular port to form described valve port.
The valve rod of described spool is shaped on conical head, and end-face seal ring is set on the rear portion of conical head again by cartridge cover and described spring clip compression set position.
The axial zone line of described housing exterior also is shaped on respectively around the taking mouthful groove and take a mouthful ridge of external peripheral surface lopping, and the outside of interface one side is shaped on the bolt face that adapts to the spanner interlock application of force.
Cylindrical outside surfaces also can be arranged in the inflation inlet one side outside of described shell, and the outside of interface one side is shaped on the bolt face that adapts to the spanner interlock application of force.
After the utility model is tightened on the refrigerant pipe joint of air-conditioning internal machine, the operator directly overlaps on the inflation inlet that is pressed in this valve with conventional inflation connecting sleeve and inflates, spool just is pressed towards and moves left, thereby driving end-face seal ring disengaging tubular port opens valve port fully, the body of inflating just can enter the refrigerant pipe of air-conditioning internal machine smoothly, and nitrogen unnecessary in the cavity is discharged.Inflation finishes, and the inflation connecting sleeve is removed (extraneous pressure elimination), the slip to the right under the pressure of spring of spool, thus drive the complete close port of end-face seal ring.
Adopt the utility model, the whole advantages that not only have original pressure retaining valve, and the structure that matches with the tubular port of outer casing inner wall of set end-face seal ring, good sealing effect not only, and the resistance of valve port when opening significantly reduces, feel more when operator inflate easily, thereby working efficiency is higher.In addition, the structure of whole valve is also simplified, and makes more convenient.

Embodiment
Below in conjunction with Figure of description, technological scheme is described further by embodiment.
This air-conditioning internal machine gas charging valve, comprise a cylindrical case 1, be shaped on the internal thread 1-1 that can be connected in the interface of shell left end with the air-conditioning internal machine refrigerant pipe, a clamping sleeve 9 (clamping sleeve is tightly fixed on the inwall of shell) is fixed at the middle part of shell inner cavity, be shaped on the passage 9-1 that several are beneficial to the inner chamber inner air flow on the clamping sleeve, other has a spool 3 to be set on the axis hole at this clamping sleeve center slidably, also has a rubber stopper 2; Above structure all with the structure of existing pressure retaining valve roughly the same.
Improvement of the present utility model is that the spool right-hand member cooperates with the inwall of shell inflation inlet 8 one ends and form to open or the valve port of throttle down, and other has one to be positioned spring 4 in the shell inner cavity and to force in spool and make spool have the potential energy of close port; Described spool right-hand member is equipped with an end-face seal ring 7, and the inwall of shell inflation inlet one end is then made tubular port 10, cooperates between end-face seal ring and the tubular port to form described valve port.
The valve rod of described spool is shaped on conical head 3-1, and end-face seal ring 7 is located by cartridge cover 6 and described spring 4 crampings at the rear portion of conical head again.
In addition, the axial zone line of the outside of described shell 1 also is shaped on taking mouthful groove 1-3 and taking a mouthful ridge 1-4 around the external peripheral surface lopping respectively, the outside of interface one side is shaped on the bolt face 1-5 (shown in Figure 5) that adapts to spanner (spanner that comprises plum blossom shaped spanner, socket wrench and other structure) the interlock application of force, and these structures all are in order to utilize existing widely used inflation connecting sleeve.With inflation connecting sleeve when inflation, the card pearl on the inflation connecting sleeve embeds when taking mouthful groove, just can inflate by charging air inlet.As another kind of structure, inflation inlet one side of the outside of described shell 1 also can be arranged to tubular profile 1-6 shown in Figure 6, and the outside of interface one side still is shaped on the bolt face 1-5 that adapts to the spanner interlock application of force.
