Description
Technical field
The present invention relates to a kind of batch valve core air-tightness test, be mainly used in the valve inside production scene to detecting the detection of valve inside opening pressure.
Background technology
Valve inside manufacturing enterprise in the valve inside production scene or the laboratory need to quick and precisely measure the valve inside opening pressure, and then judge whether valve inside qualified.Traditional valve inside opening pressure detecting device need to be screwed valve inside into the inflating valve core chamber, and then tests, and whole process need one is screwed operation, and complicated operation, inefficiency can not satisfy the demand of mass, fast detecting.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of batch valve core air-tightness test of simple to operate, high efficiency is provided.
The object of the present invention is achieved like this: a kind of batch valve core air-tightness test, and it comprises pressing machine body, cope match-plate pattern, lower bolster, exhaustion plate and tank;
Described cope match-plate pattern is fixed on workplace on the pressing machine body, described tank is arranged on the lower workplace of pressing machine body, described tank top is provided with exhaustion plate, be evenly equipped with a plurality of gas outlets on the described exhaustion plate, described gas outlet is inserted under the liquid level in the tank, described bottom of gullet is provided with level crossing, and described tank at least sightingpiston simultaneously makes for transparent material;
Be equipped with spring and slide block from top to bottom in the upper nib of described cope match-plate pattern, offer the through hole that passes through for the valve inside core bar on the described slide block;
The lower nib of described lower bolster is through hole, and the internal diameter of described lower nib and the plug washer of valve inside closely cooperate;
The position of described upper nib, lower nib and gas outlet is mutually corresponding.
It also comprises guide plate and sieve plate;
Be uniform-distribution with the tapered opening through hole on the described guide plate, described each through hole just can hold core bar and the core cap position of valve inside, and described guide plate lead to the hole site is corresponding one by one with the lower die hole location of described lower bolster;
Be uniform-distribution with tapered opening through hole of the same size on the described sieve plate, and each through hole just can hold next valve inside, the position of described sieve plate through hole is corresponding one by one with the position of the through hole of guide plate.
The preferred version of described tank is that wall is that transparent material makes all around.Described gas outlet material is the stainless steel straight tube.
Principle of work:
1, sieve plate is kept flat, valve inside is scattered on the sieve plate, hand-held sieve plate roll and pitch number is lower, after most valve insides embed through hole, scrape one time along the sieve plate surface with scraper plate, the valve inside that does not embed through hole is scraped, as still have the vacant through hole of minority, directly replenish several valve insides and put into through hole.
2, guide plate is placed on the sieve plate, and register pin just in time inserts the pilot hole of sieve plate, guide plate and sieve plate are fitted like a glove, then turn over simultaneously turnback, valve inside all falls into guide plate from sieve plate, sieve plate is proposed vertically upward again, and valve inside all is inverted in the hole of guide plate.
3, in like manner, again lower bolster is placed on the guide plate, and the register pin on the guide plate just in time inserts the pilot hole of lower bolster, lower bolster and guide plate are fitted like a glove, then turn over simultaneously turnback, valve inside all falls into lower bolster from guide plate, and guide plate is proposed vertically upward, and valve inside all just is being put in the nib of lower bolster.
4, this moment lower bolster is put on the exhaustion plate of pressing machine, by the register pin location.
5, air pressure is transferred to desired value, press shift button under the cope match-plate pattern on the pressing machine switch board, cope match-plate pattern is to bottom offset, push up to the lower bolster sealing gasket, for preventing that cope match-plate pattern from damaging valve inside by pressure, be embedded in slide block and spring in the hole of cope match-plate pattern, by initial tension of spring valve inside is pressed in the lower nib, lower nib and plug washer closely cooperate, and reach sealing effectiveness.Gas after compressing in the source of the gas enters seal cavity between the upper and lower mould by air admission hole, and after continuing for some time, cope match-plate pattern moves on will be automatically, finishes test.
6, during gas testing, as observe gas outlet in tank without Bubble formation, illustrate that the valve inside opening pressure meets set standard, if any Bubble formation, the core spring pressing power that valve inside then is described is not enough, and perhaps valve inside is assembled hourglass cored spring, and the valve inside core bar will be backed down, core body separates with core print seat, produce the gap, gas is also discharged thereupon, at this moment, according to the level crossing display position, write down the position of leakage air valve inside, press the button that moves on the cope match-plate pattern, cope match-plate pattern is to top offset, take out leakage air valve inside, and classification is put.
Compared with prior art, the invention has the beneficial effects as follows:
1, whole test platform structure is simple and safe, and is easy to operate.
2, test efficiency is high.By the application to sieve plate, guide plate, lower bolster, pack into the efficient of lower nib of valve inside is greatly improved, and once can carry out simultaneously air-tight test to hundreds of valve insides; Process of the test has been saved pack into the process that is screwed in inflating valve core chamber of traditional valve inside, and top mould medi-spring pretightning force makes plug washer and the sealing of lower nib.
3, handling safety.Be provided with infra-red ray detection device at pressing machine, if during the patrix upper and lower displacement, operator's mistake stretches into pilot region with hand, and device will be sensed this risky operation automatically, and auto stop has been guaranteed personal safety.
