Specific embodiment
This utility model provide a kind of test device for air tightness, by this device can be convenient to selling liquid machine The air-tightness of liquid communication pipeline is detected.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.
As depicted in figs. 1 and 2 (arrows in figure be the gas being filled with circulation path and direction), this practicality is new The test device for air tightness that type embodiment is provided, its can more targetedly to sell liquid machine liquid communication pipeline it is airtight Property detected, including:Air-tightness tester (not shown), the air-tightness tester are existing air-tightness survey in market Examination instrument;Cavity 1, the cavity 1 are specially designed, cavity according to the work requirements used cooperatively with the piercing mechanism for selling liquid machine 1 surrounds the inner chamber with opening, the puncture tube 2 of piercing mechanism can Jing openings extend in inner chamber, and cavity 1 can be accommodated Puncture tube 2, while the opening of cavity 1 can be tightly connected with the closure 3 of piercing mechanism, and cavity 1 and air tightness test Instrument is connected.It should be noted that not considering that outside, cavity 1 are connected with air-tightness tester in the connection of puncture tube 2 cavity 1 Under the premise of, after closure 3 is blocked to the opening of cavity 1, enable to cavity 1 inner chamber become one with it is extraneous completely every From confined space, i.e., in addition to opening, cavity 1 define one closing inner chamber.
When detecting to the air-tightness for selling the liquid communication pipeline of liquid machine using above-mentioned test device for air tightness, chamber is made The opening of body 1 is tightly connected with closure 3, while blocking the liquid outlet of liquid flow pipe so that flow pipe, 1 and of cavity Air-tightness tester connects into the test inner chamber of and external environment, is filled with gases at high pressure so that test in test inner chamber Pressure in inner chamber is more than external atmosphere pressure, and then in a period of time, (duration that test inner chamber is hedged off from the outer world, can be according to inspection Survey require different and be modified, for example duration can be a few minutes, even several days a few houres etc.) in make air-tightness tester Persistently detect to testing the pressure value in inner chamber, then contrast the detection data of different time points, if the change of data Amount judges that in the range of technological requirement, then the air-tightness of the liquid communication pipeline for selling liquid machine is good, if the variable quantity of data Beyond the scope of technological requirement, then the air-tightness of the liquid communication pipeline that liquid machine is sold in judgement is unqualified.
In the test device for air tightness that the present embodiment is provided, the structure of cavity 1 can more targetedly with sell liquid machine Closure 3 and puncture tube 2 realize coordinating, and detection data can accurately be drawn by the detection of air-tightness tester, So that the air-leakage test operation for selling the liquid communication pipeline of liquid machine is simpler easy.
In the test device for air tightness provided for further optimisation technique scheme, the present embodiment, the company of offering on cavity 1 Logical its inner chamber, and the air inlet of gases at high pressure can be filled with inner chamber, and air-tightness tester passes through air inlet and inner chamber Connection.In the present embodiment, in order to realize connecting for cavity 1 and test device for air tightness, preferably air inlet is opened up on cavity 1, Air-tightness tester is made to be tightly connected with air inlet and turn on by conduit (not shown).Additionally, the air inlet is also used for Gases at high pressure are filled with into cavity 1, in concrete setting, three-way valve can be set on the conduit connected with air inlet (in figure It is not shown), in three of three-way valve openings, one is connected with air inlet, and one is connected with source of the gas, one and air-tightness tester Connection.This kind of set-up mode, only can open up a through hole on cavity 1 and can just play inflation and connect air-tightness tester Dual function.Certainly, two through holes can also be opened up in the present embodiment on cavity 1, is respectively used to inflate and connects airtight Property tester.And the mode of above-mentioned one through hole of setting, reduce the quantity of the through hole for needing to open up on cavity 1 so that cavity 1 The sealing property of itself is more projected, so being acted on preferred version.
More preferred, inlet suction port 4 is provided with air inlet, air-tightness tester passes through inlet suction port 4 and air inlet Connection, as depicted in figs. 1 and 2.In the present embodiment, the connection of conduit and air inlet is realized for convenience, and the present embodiment preferably exists Inlet suction port 4 is provided with air inlet, inlet suction port 4 projects the periphery wall of cavity 1, and is tightly connected with air inlet so that lead Pipe directly can be socketed on inlet suction port 4, improve the convenience of attended operation, it is often more important that can also improve connection jail Solidity and sealing, provide guarantee for follow-up accurate detection.
Specifically, preferred cavity 1 is the pipe of a port sealing, as depicted in figs. 1 and 2, another port of pipe For opening.The effect of cavity 1 in the present embodiment is that instead of containing bucket, is tightly connected with the liquid communication pipeline for selling liquid machine, and then The air-tightness of liquid communication pipeline can be tested, on the premise of it can function as described above, the structure of cavity 1 can be with There are multiple choices, and in the present embodiment, in order to farthest reduce the volume of cavity 1, in order to test device for air tightness Carry and the assembling with piercing mechanism, it is preferred to use the pipe of only a port sealing is used as cavity 1, pipe it is another Individual port then keeps opening-wide state, so that used as aforesaid opening, closure 3 (is opened to the port of pipe when being connected with pipe Mouthful) sealed.In addition to the structure using pipe, cavity 1 can also be other structures, such as similar to the structure for containing bucket Deng.
Further, on the sealed end of cavity 1, the base 5 that can vertically support cavity 1 is connected with, such as Fig. 1 and Fig. 2 institutes Show.In order to ensure that cavity 1 preferably can be realized coordinating with piercing mechanism, the present embodiment is further preferably on the sealed end of cavity 1 Base 5 is connected with, by the support of base 5, the cavity 1 for enabling to circular tube shaped is kept upright state, so as to close with what is moved down Capping 3 and puncture tube 2 are coordinated, to be more applicable for detecting the air-tightness for selling liquid machine liquid communication pipeline.In addition, In the present embodiment, base 5 is preferably tabular, because 5 simple structure of flat base, it is easy to accomplish, and supporting & stablizing, institute With as preferred.Additionally, base 5 can also be other structures, for example with the frame that angle steel or rectangular tube are welded Shape structure etc..
In the present embodiment, air inlet is opened on the circumferential side wall of cavity 1, as depicted in figs. 1 and 2.Air inlet is preferably opened It is located on the circumferential side wall of cavity 1, preferably can be connected with air-tightness tester, and without the need for carrying out to piercing mechanism Change.
Each part is described by the way of progressive in this specification, what the structure of each part was stressed is With the difference of existing structure, the entirety and part-structure of test device for air tightness can be by the structures to above-mentioned some It is combined and obtains.
