Description
Technical field
The utility model belongs to valve technology field, is specially air-conditioning inflation pressurize plastic valve.
Background technique
Air conditioner needs the sealability of its refrigerant pipe is tested repeatedly in manufacture process.At present the test method to the interior machine of split-type air conditioner is to fill earlier in the refrigerant pipe of interior machine as the nitrogen leak detection, charges into helium and charge into refrigeration agent at last to carry out gas welding and seal leak detection.If all qualified then product is qualified, in said process, whichever link is found gas leakage, test again behind the release that then needs the to exit repairing pipeline.Factory's extensive mode that adopts when leak detection is at present: earlier a port of one section copper pipe is made horn mouth, this horn mouth is aimed at interior machine-processed cold pipe coupling, sealed on the machine joint in copper nut horn mouth being tightened in 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 flatten this section copper pipe with Sealing pliers, and seal with gas welding.Adopt this mode to test, operational sequence complexity not only, operator and special tool are various, working efficiency is not high, and each test all will consume one section copper pipe and a copper nut, can't reuse after sealing, and some interior machine is repeatedly repaired test and need be consumed more piece copper pipe, a plurality of copper nut and refrigeration agent, consumptive material is more, and cost is difficult to reduce.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 health of operators, and unfavorable to environmental protection.
At above-mentioned this situation, someone improves it, the following technological scheme of general employing: spool is set in the valve body, spring is set in the valve body, and the valve body middle part is provided with internal projection, and an end of spring is positioned on the stop collar, the other end is limited in internal projection, side in internal projection is provided with the rubber stopper that cooperates with seal spool, and rubber stopper one end links to each other with clamping sleeve, and the clamping sleeve the other end is limited in the rubber ring of outer end.During use, the connecting tube extruding rubber ring of locking with valve body one end compresses clamping sleeve, and clamping sleeve compresses rubber stopper, thereby reaches sealing effect.Its shortcoming is: the length of internal thread needs control in the valve body, because oversize or too short connecting tube and the rubber ring extruding degree that all can influence, influence the compression degree of rubber stopper, inflates air displacement and is difficult to control; Rubber stopper is by being provided with step and internal projection is sealed and matched, because on the rubber stopper step is set, difficulty of processing is big, and sealing effect is bad.
The model utility content
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the technological scheme that the low air-conditioning inflation pressurize plastic valve of a kind of good sealing effect, cost of production is provided.
Described air-conditioning inflation pressurize plastic valve, comprise valve body and be arranged on the interior spool of valve body, valve body one end is provided with internal thread, the middle part is provided with internal projection, it is characterized in that internal projection one side retaining connects sealing seal ring is set, valve interior wall is provided with convex shoulder, the gland that tightly is located at valve interior wall connects with the convex shoulder retaining and cooperates, gland cooperates with the seal ring compression seal, spool one end connects with seal ring movable sealing retaining and cooperates, the other end close-fitting is provided with valve core housing, and valve core housing and valve interior wall are slidingly matched, and the valve core upper sleeve between valve core housing and the internal projection connects spring is set.
Described air-conditioning inflation pressurize plastic valve is characterized in that being provided with on the internal projection protruding circle, and seal ring and protruding circle elasticity press and is sealed and matched.
Described air-conditioning inflation pressurize plastic valve is characterized in that the gland exterior edge face is a plane structure.
Described air-conditioning inflation pressurize plastic valve, the arc convex end that it is characterized in that spool keeps off connecing with the seal ring movable sealing and cooperates.
Described air-conditioning inflation pressurize plastic valve is characterized in that spool the other end close-fitting is arranged in the endoporus of valve core housing.
Described air-conditioning inflation pressurize plastic valve is characterized in that being provided with on the valve core housing convex tendon.
Above-mentioned air-conditioning inflation pressurize plastic valve, not only operation is simple, testing cost is low, and owing to seal without gas welding, refrigeration agent volatilization phenomenon has effectively guaranteed the healthy of staff when having avoided gas welding to seal fully, has optimized the workshop air quality, reduce pollution of atmosphere, ensured safe generation.Most importantly the gland that tightly is located at valve interior wall directly cooperates with the seal ring compression seal, and connects by the convex shoulder retaining, does not need connecting tube extruding gland to compress seal ring, and the compression degree of seal ring is fixed, and the inflation air displacement can accurately be controlled; Seal ring and internal projection press by protruding circle elasticity and are sealed and matched, and further improve sealing effect, and owing to do not need to make step on the seal ring, process more convenient.This simple in structure, stable, good sealing effect.In addition, this pressure retaining valve adopts plastics to make, and can reduce the cost of complete machine under the prerequisite of guaranteeing the air-conditioning quality.
