Description
[technical field]
The utility model relates to valve member, relates in particular to a kind of quick enclosed valve that is used for the closed system pressurize.
[background technique]
Closed system need be tested the circulatory system seal of self in the process of producing; The test method that adopts in the industry at present; Mainly be in system, to charge into a certain amount of high pressure to show track gas; Carry out solder up then, then use detecting instrument that each solder joint or system's rapid wear point are hunted leak; Or filled highly pressurised liquid, pressurize is seen whether pressure descends, and is searched leakage point, all passes through if detect, and then is regarded as the acceptable product warehouse-in, as detects defectively, then need reprocess, and then detect.In the process of reprocessing, owing to used welding procedure, emit high pressure Tracer gas or highly pressurised liquid after then will destroying to sealing of weld, need carry out welded seal to perfusing hole again after reprocessing completion.Here just cause: the one, the waste resource can cause the waste of wlding, scolder, inflammable gas in the rework process; The 2nd, increase personnel cost, owing to use this characterization processes once more, then need drop into one of welder, weld reprocessing sealing after the detection; The 3rd, prolong and detect man-hour, owing to reprocess too complicacy of technology, working efficiency is not high, needs reprocess more man-hour; The 4th, increase environmental pollution, owing to adopt solder up technology, irregular owing to sealing, the very difficult completion of Tracer gas that causes when reprocessing, pouring in the system reclaimed, and environment is polluted.
[model utility content]
The utility model provides a kind of and reprocesses conveniently, can fill, put the quick enclosed valve that high pressure Tracer gas or highly pressurised liquid are used for the closed system pressurize fast.
In order to realize the foregoing invention purpose, the technological scheme that the utility model adopts is:
A kind of quick enclosed valve that is used for the closed system pressurize; Comprise valve body, guide pad and T type spool; Guide pad is fastening to be assemblied in the body cavity; T type spool passes guide pad and is set in the valve body, and the top of valve body offers the taper inlet hole, the bottom of T type spool be set with valve body in first seal bowl that cooperates of ring cone seal portion; But the top socket of T type spool is fixed with second seal bowl of shutoff valve body top taper inlet hole, on the T type spool between the guide pad and second seal bowl, also is arranged with the elastic component that coupling mechanism force is provided to second seal bowl.
The fitting surface of ring cone seal portion is the conical surface in said first seal bowl and the valve body.
The fitting surface that said second seal bowl is used for sealed valve body top taper inlet hole is a hemisphere face.
Said second seal bowl is a conoid type, and its inner chamber is the blind hole that is provided with 4 pairs of 8 strip projections, and the second seal bowl interference is set in the top of T type spool.
Said guide pad is " cross " structure, offers circular groove on the guide pad outer edge surface, corresponding body cavity be provided with the guide pad outer edge surface on circular groove cooperated the circular protrusion of spacing fixation.
The connecting end of said valve body and closed system is the internal thread linkage structure, and the bottom of internal thread linkage structure is provided with seal washer.
Said elastic component is a spring.
The outer rim at said valve body top also is provided with and the positioning ring that fills a snap fit.
The beneficial effect of the utility model is:
The utility model is according to the characteristics of closed system test technology; Through set up the quick enclosed valve that is threaded at the inflation end of closed system, utilize first seal bowl and second seal bowl in the valve, can be automatically seal filling the apparent track gas of a high pressure that head charge in the closed system; The design of employing double-sealing; When spring reset sealed it, double sealing structure can be more effective, and the i.e. sealing at the second seal bowl place in secondary seal place is except having increased to whole system the secondary FW; Also the remaining refrigerant in spring section place is sealed the problem of false alarm when having effectively reduced check; The sealing mode is cancelled the welding of past to closed system inflation end closure, and is simple to operate, quick and convenient, both saved human cost and cost of material, can when reprocessing, reclaim high pressure again easily and show track gas, avoids high pressure to show the pollution of track gas to environment.

[embodiment]
Extremely shown in Figure 8 like Fig. 1; A kind of quick enclosed valve that is used for the closed system pressurize; Comprise valve body 1, guide pad 2 and T type spool 3, guide pad 2 fastening being assemblied in valve body 1 inner chamber, T type spool 3 passes guide pad 2 and is set in the valve body 1; The top of valve body 1 offers taper inlet hole 10; The bottom of T type spool 3 is set with first seal bowl 4 that cooperates with the valve body 1 interior ring cone seal 1a of portion, but the top socket of T type spool 3 is fixed with second seal bowl 5 of shutoff valve body 1 top taper inlet hole 10, on the T type spool 3 between the guide pad 2 and second seal bowl 5, also is arranged with the spring 6 that coupling mechanism force is provided to second seal bowl 5.
Like Fig. 5 and shown in Figure 6, first seal bowl 4 is conical surface 4a with the fitting surface of the valve body 1 interior ring cone seal 1a of portion.
Like Fig. 7 and shown in Figure 8; The fitting surface that second seal bowl 5 is used for sealed valve body 1 top taper inlet hole 10 is hemisphere face 5a; Wherein second seal bowl 5 is a conoid type, and its inner chamber is the blind hole that is provided with 4 couples 8 strip projection 5b, and 5 interference of second seal bowl are set in the top of T type spool 3.
As shown in Figures 2 and 3; Guide pad 2 is " cross " structure, adopts this class formation can increase the through hole in the valve body 1, and is little to the obstruction of gas or liquid when filled; This structure can effectively the motion in valve body 1 limits to T type spool 3 simultaneously; T type spool 3 can not be swung arbitrarily when motion, reset accurately, repeat good seal performance; Offer circular groove 2a on the guide pad outer edge surface, corresponding valve body 1 inner chamber be provided with guide pad 2 outer edge surfaces on circular groove 2a cooperated the circular protrusion 1b of spacing fixation.
As shown in Figure 1, valve body 1 is the internal thread linkage structure with the connecting end of closed system, and the bottom of internal thread linkage structure is provided with seal washer 7, and the outer rim at valve body 1 top also is provided with and the positioning ring 8 that fills a (not shown) snap fit.。
During use, as shown in Figure 9, utilize the filled head of standard to block the positioning ring 8 on the valve body 1; This moment second, seal bowl 5 was moved by the top to the left; Valve body 1 top taper inlet hole 10 is opened, and first seal bowl 4 and then moves under the effect of T type spool 3, and this moment, the interior wall passage of valve body 1 was switched on; Under the effect of pressure, accomplish the inflation of closed system; Inflation is withdrawn inflator after accomplishing, and T type spool 3 drives first seal bowl 4 and second seal bowl 5 is moved to the left the completion sealing under the effect of spring force and internal pressure.This sealing means cancellation past is to the welding of closed system inflation end closure, and is simple to operate, quick and convenient, both saved human cost and cost of material, can when reprocessing, reclaim high pressure again easily and show track gas, avoids high pressure to show the pollution of track gas to environment.
The above embodiment just is the preferred embodiment of the utility model, is not the practical range that limits the utility model with this, and the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by in the protection domain of the utility model.
