Description
Technical field
The utility model relates to a kind of self sealing valve that is used for air-conditioning internal machine, belongs to technical field of mechanical structures.
Technical background
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.In said process, no matter which link finds that gas leakage is arranged, and the release of then need exitting is tested after repairing pipeline again.Factory's extensive mode that adopts when hunting leak is at present: elder generation makes horn mouth to a port of one section copper pipe, and this horn mouth is aimed at interior machine-processed cold pipe coupling, with copper nut horn mouth is tightened on the interior machine joint to be sealed again; Then charge into test gas to authorized pressure from the another port of this section copper pipe and hunt leak with the special-purpose connector of inflating; When hunting leak with refrigeration agent at last, need to flatten this section copper pipe with Sealing pliers earlier, and seal with gas welding.Adopt this mode to test, operational sequence complexity not only, operator and special tool are various, and working efficiency is not high; And each test all will consume one section 10 copper pipe to skilful centimeter length (after sealing can't reuse) and a copper nut, and some interior machine is repeatedly repaired test and then need be consumed many sections copper pipes, a plurality of copper nut and refrigeration agent, and consumptive material is more, and cost is difficult to reduction.In addition, when using gas welding to seal, the fracture end leaks and residual refrigeration agent is met the heat volatilization, has not only directly polluted workshop condition, threatens operator's body health, befouling environment.The patent No. is that 200320109072.7 Chinese utility model patent discloses a kind of valve, and it has solved the problems referred to above substantially, but its spool location in the process of inflation is unstable, and gas is not smooth, poorly sealed in spool circulation not.
Summary of the invention
The enclosed valve that provides a kind of air-conditioning internal machine to use is provided the utility model purpose, has solved the problems referred to above that prior art exists.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of self sealing valve that is used for air-conditioning internal machine, comprise shell and be located at its interior spool, also be provided with spring in the shell, one end of spring is positioned to be located on the interior setting sleeve of shell, setting sleeve is positioned to be provided with in the enclosure the rubber ring, it is characterized in that: described spool middle part is provided with the conical surface projection that matches with the plug that places shell one end inboard, and described valve core housing is provided with the spring stop collar, the spring stop collar is provided with some convex ridges, and the other end of described spring is positioned on the convex ridge.
The one side of convex ridge contacts with the conic convex of spool, and the other end and spring match, and spring is by the convex ridge effect.Because the existence of convex ridge makes that flowing of air-flow is very smooth and easy.Convex ridge and shell closely cooperate simultaneously, and its existence makes and is difficult for swing by the more stable of spool.If the conical surface that described conical surface is not necessarily strict, in fact if cross section for circle can with the plug of the present utility model sealing that matches.
This is that the other end of shell is that threaded end links to each other with inflator, when shell and inflator screw thread tighten, the end face extrusion rubber ring of inflator, setting sleeve and spring, spring stop collar, conical surface projection are transmitted stressed, cause conical surface projection and plug to closely cooperate, when the other end and other port of valve match the jail, one end of spool is pushed up, at this moment spring from two ends stressed being compressed, conical surface projection and plug from, valve body is switched on.
As preferably, described shell internal layer tightly is provided with the plug clamping sleeve, and described plug clamping sleeve one end is pushed down plug, and the other end is positioned rubber ring.The plug clamping sleeve entangles spool, spring, setting sleeve, and two ends are positioned plug and rubber ring respectively, and when threaded port was tightened, the plug clamping sleeve compressed plug, and this makes that the sealing of plug and spool is tighter.
As preferably, an end of the endoporus of described setting sleeve and spool cooperates, and setting sleeve is provided with some vent slots.One end of spool can insert in the setting sleeve, and spool is stable better like this, the endoporus of setting sleeve and and plug clamping sleeve contacting part between some vents are set, vent can make that valve body is the effect that can bring into play retaining spring and conducting air-flow better in conducting.
As preferably, described spring and plug clamping sleeve closely cooperate.Make spring and plug clamping sleeve, closely cooperate, spring can disturbance in the process of compression.Simultaneously, the sealing of the present utility model end that is not arranged on shell has reduced the breakage of gas.
Therefore, the utlity model has characteristics such as stable, firm, good sealing effect, gas flow be smooth and easy.
