Abstract
The utility model provides a sealing valve of an air conditioner. The sealing valve comprises a shell and a valve core, wherein internal screw threads are arranged on the tail part of the shell; a rubber plug compressing sleeve is arranged on the inner side of the front part of the shell; a rubber plug is arranged at the front end of the rubber plug compressing sleeve; a steel ring is arranged on the rear part of the rubber plug compressing sleeve; a positioning sleeve is arranged on the steel ring; the rear end of the valve core is inserted into the positioning sleeve; the front end of the valve core is fixed with the rubber plug in a compressing way; a shell inflating hole is formed in the head of the valve core; a spring is arranged on the valve core; a positioning sleeve is arranged at one end of the spring; the other end of the spring is arranged on the valve core; the inner hole of the positioning sleeve is tightly matched with the tail part of the valve core; a plurality of ventilating grooves are formed in the positioning sleeve; screw threads can lock the valve together with other fitting pipes; and the steel ring, the rubber plug compressing sleeve and the rubber plug are tightly connected with the shell. The sealing valve has the beneficial effects that the sealing valve is inflated at one time and is completely closed, can be continuously and repeatedly inflated, and is high in working efficiency and good in sealing effect.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of sealed valve of air conditioner.
Background technique
Air conditioner needs its refrigerator pipes is tested repeatedly in the manufacture process again, test mode is to pour nitrogen, helium and refrigeration agent repeatedly to hunt leak, in case finding to have gas leakage need test after pipeline is repaired in the venting release again, valve uses frequent, existing valve uses at every turn and need reinstall, very bother, and sealing effect is bad, and gas leak phenomenon is often arranged.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of sealed valve of air conditioner is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of sealed valve of air conditioner, comprise shell and spool, it is characterized in that the shell afterbody is provided with internal thread, the anterior inboard of shell is provided with the plug clamping sleeve, plug clamping sleeve front end is provided with plug, the rear portion is provided with steel ring, and steel ring is provided with setting sleeve, and the spool rear end is injected in the setting sleeve, front end and plug extruding are fixing, and the head of spool is provided with the shell air-filled pore.
Further, described spool is provided with spring, and spring one end is arranged on the setting sleeve, and an end is arranged on the spool, and described spring is many.
Further, the endoporus of described setting sleeve and the afterbody of spool closely cooperate, and setting sleeve is provided with some vent slots.
Further, described screw thread and other ducts are locked valve together.
Further, described steel ring, plug clamping sleeve and plug closely link to each other with shell respectively.
The utlity model has following beneficial effect:
The sealed valve of air conditioner of the present utility model, inflation is once closed fully, repeated inflation continuously, high working efficiency, good sealing effect.

Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As a kind of mode of execution of the present utility model, consult Fig. 1, a kind of sealed valve of air conditioner comprises shell 1 and spool 2, shell 1 afterbody is provided with internal thread 10, shell 1 anterior inboard is provided with plug clamping sleeve 5, and plug clamping sleeve 5 front ends are provided with plug 6, and the rear portion is provided with steel ring 3, steel ring 3 is provided with setting sleeve 4, spool 2 rear ends are injected in the setting sleeve 4, and front end and plug 6 extruding are fixing, and the head of spool 2 is provided with shell air-filled pore 9.
During use, shell 1 rear end is locked by the pipeline that screw thread 10 matches with it, tightly suppress steel ring 3, steel ring 3 presses plug clamping sleeve 5, and then extruding plug 6, plug 6 is moved forward contact with spool 2 to fluff, the shell inflation inlet 9 of shell 1 front end blocks and is inflated device, be arranged on the thimble that is inflated in the device and will back down spool 2, spring 8 shrinks, and spool 2 separates with plug 6, valve body will conducting like this, gas flows by vent slot 7, after finishing the work, as long as disconnect shell inflation inlet 9, spring 8 resiliences, spool 2 closely pushes with plug 6 again, cooperatively interacts good sealing effect.
In sum; the utility model only is illustrated an embodiment of the sealed valve of air conditioner; but the utility model is not limited thereto; it will be appreciated by those skilled in the art that under the situation that does not break away from the protection domain that claims of the present utility model put down in writing and to change arbitrarily and to revise.
