Abstract
The utility model relates to a valve for air-conditioning evaporators belonging to the technical field of the mechanical structure and comprises an outer shell, a spool arranged inside the outer shell, and a spring arranged inside the outer shell. The utility model is characterized in that the middle portion of the outer shell is provided with an inner convexity, one end of the spring is locationally arranged on a spring limit sleeve which is in the one end of the outer shell, and another end of the spring is limitedly arranged on the inner convexity. One end of a curved convex area spool is arranged on an inner sleeve of the spring with another end being sleeved in the inner hole of the spring limit sleeve. The spool is fixedly connected with the spring limit sleeve and one side of the inner convexity is provided with a rubber plug which is sealedly engaged with the curved convex area. The utility model has the advantages of a strong structure, stabilization and good sealing effect or the like.
Description
Technical field
The utility model relates to a kind of valve that is used for A/C evaporator, 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 utility model purpose is the valve of using on a kind of A/C evaporator is provided, and 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 valve that is used for A/C evaporator, comprise shell and be located at its interior spool, also be provided with spring in the shell, it is characterized in that: described shell middle part is provided with internal projection, one end of spring is positioned to be located on the interior spring stop collar of shell one end, the other end of spring is limited in internal projection, be arranged with the spool that an end is an arc convex in the spring, the spool the other end is sheathed in the endoporus of spring stop collar, and spool is fixedlyed connected with the spring stop collar, is provided with the rubber stopper that is sealed and matched with arc convex in a side of internal projection.The middle part of shell is provided with internal projection, internal projection is a circle, both sides one side of projection is used for limit spring, one side is used for spacing rubber stopper, the arcuation projection of spool end and rubber stopper seal cooperate, and described arcuation projection can be the also shape that matches of ellipsoid or other and rubber stopper of conical surface.
As preferably, described rubber stopper one end links to each other with the clamping sleeve of tightly being located in the shell, and the other end of described clamping sleeve is limited in setting rubber ring in the enclosure.The inwall of rubber ring and shell is close to, and two ends are relative with rubber ring with rubber stopper respectively, and clamping sleeve extruding rubber stopper makes it closely knit when rubber ring is subjected to inside extruding.
As preferably, the spring stop collar is provided with some convex ridges, and described spring stop collar partly is sheathed in the spring.Convex ridge can limit the disturbance of spool, and the space between convex ridge and the shell makes gas flow be very easy to simultaneously.
Therefore, the utlity model has characteristics such as sound construction, stable, good sealing effect.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is structural representations of spool;
Accompanying drawing 3 is structural representations of spring stop collar.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as Fig. 1,2, shown in 3, the rubber ring 7 of cylinder type is arranged on the inside of shell 1, its be positioned at screw thread port near, one end of clamping sleeve 6 links to each other with rubber ring 7, rubber ring 7 tightly is located in the shell 1, its opposite side links to each other with rubber stopper 4, rubber stopper 4 is limited in internal projection 10, the cross section of internal projection 10 is an annulus, its both sides are provided with rubber stopper 4 and spring 3 respectively, role also is the displacement of restriction rubber stopper and spring, spool 2 is by internal projection 10, one end of spool 2 is an ellipsoid, and spool 2 is sealed and matched by the ellipsoid and the rubber stopper 4 of end, and the other end of spool 2 is sheathed in the endoporus of spring stop collar 9, being arranged with an end in the spring 3 is the spool 2 of arc convex 5, spool 2 the other ends are sheathed in the endoporus of spring stop collar 9, and spool 2 fixedlys connected with spring stop collar 9, are provided with the rubber stopper 4 that is sealed and matched with arc convex 5 in a side of internal projection 10.Rubber stopper 4 one ends link to each other with clamping sleeve 6 in tightly being located at shell 1, and the other end of described clamping sleeve 6 is limited in and is arranged on the interior rubber ring 7 of shell 1, and described spring stop collar 9 is provided with some convex ridges 8, and described spring stop collar 9 parts are sheathed in the spring 3.
During use, with the internal thread of an end of shell and the pipeline locking that matches with it, press rubber ring 7, rubber ring compresses clamping sleeve, clamping sleeve extruding plug, the other end of shell and be inflated device and take mouthful ridge 12 card jails by being located on the shell is arranged on the thimble that is inflated in installing pipes and backs down spool, at this moment valve body is switched on, and can finish inflation.
