With the advantages of convenient operation, high reliability and long service life, the utility model used for testing the air-tightness of the accumulator is not only suitable for compressed-air system, but also suitable for vacuum pumping system.
Description
The utility model relates to a kind of bubble-tight device of accumulator that is used to detect, and belongs to plurality of fluid pressure gauges.
Impermeability is important technology index in the accumulator manufacture process.Impermeability does not reach requirement will make electrolytic solution leak outside or single compartment short circuit and cause waste product, is to guarantee the requisite test item of accumulator product quality so impermeability detects.At present the manual air-tightness detection device that uses of factory is the push switch formula, and it is to utilize emulsion tube " compressing " and " relievings " to control the pass of gas circuit, open (figure one), exist operate inconvenient, poor reliability, serviceable life weak point disadvantage.
The purpose of this utility model is in order to overcome the shortcoming that existing air-tightness detection device exists, to provide a kind of easy to operate, reliable operation, the accumulator air-tightness detection device of long service life.
The utility model is achieved through the following technical solutions.Air-tightness detection device comprises tensimeter (13), matrix (1), admission piece (14) and glue head (6), it is characterized in that matrix (1) is by piston cylinder (2), cover (3) in the piston cylinder, piston rod (4) links to each other with glue head (6), there is a wireway (12) to link to each other on the matrix (1) with the bottom of piston cylinder (2), cover (3) is by being threaded in the bottom of piston cylinder (2) in the piston cylinder, piston rod (4) is contained in the piston cylinder and also can slides along its axis direction in the cover, the first half of piston rod has a round table surface (15), pressure spring is equipped with in round table surface (15) top, piston rod (4) middle (axially) has a upper end to shut, the endoporus that the lower end communicates with glue head (6), piston rod (4) top has aperture (16) (being generally 2-4), have not connected endoporus in the matrix, one end of left hole communicates with admission piece (14), the other end is by wireway (12) and piston cylinder (2), cavity in the piston cylinder between cover (3) and the piston rod (4) communicates, matrix (1) right side endoporus one end communicates with tensimeter (13), the other end also with piston cylinder (2), cavity in the piston cylinder between cover (3) and the piston rod (4) communicates, in piston rod (4), cushion rubber (7) is equipped with on cover (3) top respectively in piston cylinder inwall and the piston cylinder, (8), (10), (9).Cover, piston rod, wireway can be made by metal materials such as copper, aluminium, iron and alloys thereof in above-mentioned matrix, admission piece, piston cylinder, the piston cylinder.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 2 is a structural drawing of the present utility model.
The admission piece (14) in matrix (1) left side joins with source of the gas, pressurized air is by admission piece (14), the round table surface (15) that matrix (1) left side endoporus, wireway (12), piston cylinder (2) enter piston rod (4) is to overlap the space (this space claims the pressurize chamber) between (3) in lower part and piston cylinder (2), the piston cylinder, this moment is because under spring (11) effect, the lower plane of round table surface (15) and cushion rubber (9) compress, and stop pressure gas to enter tensimeter and accumulator.When detecting, hold matrix (1), glue head (6) venthole is aimed at storage battery liquid filling opening, when subordinate presses, liquid injection port stops that piston rod (4) moves downward, at this moment spring (11) is compressed, piston cylinder and interior cover thereof with respect to piston rod (4) to lower slider, round table surface (15) is left with cushion rubber (9), pressure gas enters the space between piston rod (4) top and piston cylinder (2) top, part pressure gas is by the gap between piston rod (4) top and piston cylinder (2) upper inside wall, endoporus enters tensimeter (13) through matrix (1) left side, part pressure gas passes through piston rod top aperture (16), through piston rod (4) endoporus, and glue head (6) endoporus, enter the accumulator inner chamber.This is a gas replenishment process, and its pressure is shown by tensimeter.
When pressure reaches predetermined value, hand continues to press down, spring (11) is further compressed, piston cylinder (2) and interior cover (3) thereof with respect to piston rod (4) further to lower slider, when table top compresses in the middle part of piston rod round table surface (15) goes up plane and O-ring seal (10) and piston cylinder (2), pressure gas is cut off, but this moment, tensimeter and the gas circuit of accumulator inner chamber still communicated, if tested accumulator is air tight, then the tensimeter indicating value is constant, descend gradually as the tensimeter indicating value, the tested lattice of expression accumulator have gas leak phenomenon, thereby have reached the bubble-tight purpose of detection accumulator.
When portable, glue head (6) leaves liquid injection port, under the effect of compression spring (11) elastic force, piston rod (4) resets, round table surface (15) compresses with cushion rubber (9), and compressed gas source is cut off, the pressure gas emptying in accumulator and the tensimeter, the tensimeter indicating value reduces to zero, and whole test process is finished.
In sum, by the automatic switch that the round table surface (15) on the piston rod (4) and cushion rubber (9), (10) and spring (11) are formed, under the effect of the power of detection, can finish source of the gas, inflation, pressurize, four processes of cut-out source of the gas opened automatically.
In the actual accumulator impermeability of carrying out when detecting, said process is very fast, except that pressure maintaining period paused 3 seconds by standard code, other processes are carrying out continuously of not stopping, only need about 0.5 second time altogether, subordinate process of pressing has just in time been finished the process of inflation, pressurize 3 seconds, mention, whole testing process is finished.This has just saved the time that existing apparatus is opened off switch, can improve detection speed 30%, has alleviated labour intensity, and it is easily aging to have overcome in the existing apparatus emulsion tube simultaneously, needs the disadvantage often changed, the reliability and the serviceable life of having improved pick-up unit.
This accumulator air-tightness detection device is not only applicable to compressed air system and is applicable to pumped vacuum systems.
