Description
Technical field
The utility model relates to air-tight test technical field in mechanical field, specifically a kind of low pressure air tightness tester.
Background technology
In mechanical processing process, the part that part is processed is needed to carry out air seal test, when existing various air seal test, it is common that to utilize existing source of the gas, as the compressed air in compressed air, oxygen or nitrogen cylinder that air compression station produces is tested.But having a kind of anti-vacuum valve and oil transportation conduit when doing air seal test, required pressure is the lowest.If, with existing source of the gas, the source of the gas that provided is minimum also 0.6MPa, it is impossible to meet test requirements document, and owing to the pressure reduction of required several low voltage value is the biggest, if being to take into account every test requirements document with one group of pipeline.Accordingly, it would be desirable to exploitation design is a kind of meets the device of the airtight test requirements document of low pressure to carry out air seal test.
Utility model content
The technical problems to be solved in the utility model is for problem present in background technology, it is provided that a kind of low pressure air tightness tester.
For solving above-mentioned technical problem, the technical scheme that this utility model is used is: a kind of low pressure air tightness tester, including controlling switch, air-source inflow pipe joint, air relief valve, Pressure gauge, product air inlet pipe joint, integral frame, described control switch is arranged in integral frame, described air-source inflow pipe joint is connected with many set products air inlet pipe joint by pipeline, and it is separately positioned on interior integral frame both sides, described air relief valve, Pressure gauge and control switch are arranged between air-source inflow pipe joint and product air inlet pipe joint, described product air inlet pipe joint is connected by product admission line plug.
Further, described air inlet pipe joint is set to four, is divided into two groups to be connected with described air-source inflow pipe joint, and is provided with the reducing valve pressure gage of two different ranges from product air inlet pipe joint between the pipeline that air-source inflow pipe joint connects.
Further, being provided with air filter between the pipeline that described air-source inflow pipe joint is connected with product air inlet pipe joint, described air filter is arranged on the rear end of air-source inflow pipe joint.
Further, bottom described integral frame, it is provided with rotation wheel.
Use a kind of low pressure air tightness tester of the present utility model, after to reducing pressure more than the source of the gas of actual requirement, become required various low pressure thus reach the device of test requirements document, solve special low-atmospheric pressure test and detect the problem being difficult to, and can multichannel test simultaneously, substantially increase production, work efficiency, save cost, there is simple in construction, easy to operate, practical feature.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 is the schematic diagram of this utility model low pressure air tightness tester；
Fig. 2 is structural representation of the present utility model.
Shown in figure: 1-control switch, 2-air-source inflow pipe joint, 3-air relief valve, 4-Pressure gauge, 5-reducing valve pressure gage, 6-product air inlet pipe joint, 7-plug, 8-integral frame, 9-rotate wheel.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of low pressure air tightness tester of the present utility model, including controlling switch 1, air-source inflow pipe joint 2, air relief valve 3, Pressure gauge 4, product air inlet pipe joint 6, integral frame 8, the described switch 1 that controls is arranged in integral frame 8, described air-source inflow pipe joint 2 is connected with many set products air inlet pipe joint 6 by pipeline, and it is separately positioned on the internal both sides of integral frame 8, described air relief valve 3, Pressure gauge 4 and control switch 1 are arranged between air-source inflow pipe joint 2 and product air inlet pipe joint 5, described product air inlet pipe joint 6 is connected by product admission line plug 7.
Further, described product air inlet pipe joint 6 is set to four, is divided into two groups to be connected with described air-source inflow pipe joint 2, and is provided with the reducing valve pressure gage 5 of two different ranges from product air inlet pipe joint 6 between the pipeline that air-source inflow pipe joint 2 connects.Four product air inlet pipe joints 6 are set, its purpose make more convenient operation, can work efficiency high.Meanwhile, the reducing valve pressure gage 5 of different range is set, different low voltage value can be read very easily.
Further, being provided with air filter between the pipeline that described air-source inflow pipe joint 2 is connected with product air inlet pipe joint 6, described air filter is arranged on the rear end of air-source inflow pipe joint 2, arranges the purpose of air filter, can make to be kept clean, in order to avoid affecting service precision by trial product.
Further, bottom described integral frame 8, it is provided with rotation wheel 9, its objective is to facilitate integral frame 8 to move, fix and operation.
In actual use, use a kind of low pressure air tightness tester of the present utility model, during use, first source of the gas is connected on air-source inflow pipe joint 2 by pipeline, respectively product air inlet pipe joint 6 and plug 7 are connected by admission line, rotate adjustment two air relief valve 3, reducing valve pressure gages 5 the most respectively and determine its pressure so that it is respectively reach or close to stopping adjustment during required low pressure.When starting to test, slow rotary control switch 1 respectively, allows the low-pressure gas after air filter (not marking in figure) filters enter product, now observes Pressure gauge 4, when reaching test pressure value, closing control switch 1, and carry out pressurize or venting according to test requirements document.
Use a kind of low pressure air tightness tester of the present utility model, after to reducing pressure more than the source of the gas of actual requirement, become required various low pressure thus reach the device of test requirements document, solve special low-atmospheric pressure test and detect the problem being difficult to, and can multichannel test simultaneously, substantially increase production, work efficiency, save cost, there is simple in construction, easy to operate, practical feature.
Protection domain of the present utility model is not limited only to the technical scheme disclosed in detailed description of the invention; the foregoing is only better embodiment of the present utility model; it is not limiting as this utility model; every any trickle amendment, equivalent and improvement made according to the technical solution of the utility model, within should be included in the protection domain of technical solutions of the utility model.
