Description
[technical field]
The utility model relates to a kind of air-tightness detection device, and is especially a kind of by utilizing air pressure that the water channel of the product that needs water flowing cooling is carried out the device that sealing detects.
[background technology]
In actual applications, there are a lot of products all sealing to be had higher requirements, the conventional method that product hermeticity is detected is behind product sealing area injection pressure air, again with in big pond of the whole immersion of product, whether there is bubble to emerge by observation and can whether judges sealing, if there is bubble to emerge, also can remedy according to the particular location inspection that bubble is emerged.But also there are a lot of products or parts can not adopt said method to detect; for example some needs the components and parts on the product of water flowing cooling can not get wet at all; getting wet to cause these expensive device destruction, therefore must seek a kind of product device of can protecting and can conveniently carry out the method that sealing detects again.
[utility model content]
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and proposes a kind of air-tightness detection device, and this device can detect the product of water channel sealing and not make this damage of product, again the impermeability of testing product well.
The utility model solves the problems of the technologies described above the technological means that is adopted and comprises, a kind of air-tightness detection device is proposed, comprise the control gas circuit, wherein: described control gas circuit is connected with filtering pressure reducing valve by tracheae, the two-bit triplet stop valve, divide the gas joint, 2/2-way stop valve and tensimeter are connected with product to be detected by this control gas circuit and carry out the impermeability detection.
The utility model further preferred version is: described product to be detected includes the mouth of a river and water delivering orifice, and the terminal of described control gas circuit is connected with the water inlet that waits testing product, and described water delivering orifice stops up by seal plug.
The utility model further preferred version is: described control gas circuit comprises several gas circuit branch roads.
Compared with prior art, the air-tightness detection device that the utility model provides, by designing a control gas circuit, can carry out the detection of water channel sealing to the various products of water flowing cooling that need by pressure air, can not only guarantee that detected product can not be damaged and simple and efficient to handle, also can reach very high production efficiency by the detection branch that increases this frock.
[description of drawings]
Fig. 1 is a control gas circuit planar structure synoptic diagram of the present utility model.
[embodiment]
In order to further specify principle of the present utility model and structure, now in conjunction with the accompanying drawings preferred embodiment of the present utility model is elaborated.
As shown in Figure 1, the described air-tightness detection device of the utility model embodiment is the detection of the water channel sealing of product assembling is finished after, before the water flowing use that need to be used to the water flowing cooling.
The described air-tightness detection device of the utility model embodiment comprises the control gas circuit, this control gas circuit comprises that pneumatic element has filtering pressure reducing valve 1, three-way cut-off valve 2, divide gas joint 3, two logical stop valve 4 and precision pressure gauges 5, described pneumatic element connects by tracheae, is connected with product 6 to be detected by this control gas circuit and carries out the impermeability detection.
The described product to be detected of the utility model embodiment includes water inlet and water delivering orifice, when detecting, the tracheae of control gas circuit terminal is connected with the water inlet of product 6 to be detected, and stop up closely with the water delivering orifice of seal plug 7 with product, going into of product that water flowing cooling requires generally arranged, water delivering orifice is usually designed to pagoda joint or rapid-acting coupling, so being connected still eaily of the tracheae of detected product and this gas tightness detection frock, seal plug 7 also is like this with being connected of product 6 to be detected, but must guarantee the good seal of linkage section, otherwise might cause erroneous judgement product hermeticity.
Present embodiment is when detecting, after the described control gas circuit of product 6 access the utility model embodiment to be measured, open three-way cut-off valve 2 and two logical stop valves 4 again to introduce pressure air, the knob of turn filtering pressure reducing valve transfers to required pressure with pressure air again, the air pressure of adjustment process from low to high, close two logical stop valves 4 again, the sealing quality of detected product is promptly known in the change of looking into the precision pressure gauge displayed value by sight in half an hour then.In the air-tightness detection device of the utility model embodiment, parameter is to be provided with like this: the air pressure of pressure air transfers to 0.56MPa, and the standard whether the judgement product seals is that the gas leakage pressure of product in half an hour should be lower than 0.02MPa.After test is finished, close three-way cut-off valve 2 earlier, open two logical stop valves 4 again, the pressurized air in the at this moment detected product just can be emitted, and takes off test product again and gets final product.
The described control gas circuit of the utility model embodiment comprises several gas circuit branch roads, be that to detect the gas circuit branch roads with two be example in Fig. 1 of present embodiment, but in fact, this Device Testing gas circuit branch road can be made many arbitrarily, can determine to detect the quantity of gas circuit branch road according to the required production efficiency of reality, only need to change or increase and divide gas joint 3, increase detection branch again and get final product.Because be fully independently between all detection branch in use, be all to be fully independently spatially or in time.In the specific implementation, need to use material such as raw material band to access assurance with the air-tightness of guaranteeing frock itself.
Below only be preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, so the equivalent structure that all utilization the utility model instructionss and accompanying drawing content are made changes, all be included in the protection domain of the present utility model.
