Simple in design and high in practicability, the valve air-tightness detection device of the utility model is convenient to operate and is suitable for detection of air tightness of valves of various specifications on nitrogen making machines.
Description
Technical field:
The utility model relates to a kind of valve impermeability and detects, and especially relates to the air-tightness detection device of the valve that uses in nitrogen making machine.
Background technology:
In the production of nitrogen making machine, need to use the valve of a plurality of different sizes.To utilize gas to decompose to make in the nitrogen making machine, so require very high to the impermeability of valve.Though the valve of buying all dispatches from the factory through manufacturer's check, because the decomposition of gas itself just needs to have certain risk under the high-temperature situation in the nitrogen making machine, if the pressure instability in the pipeline, the gas that lets out can cause blast.Therefore, in order to guarantee to decompose rear product quality, simultaneously, when production and application, guarantee impermeability, so to using the valve in nitrogen making machine needing to detect, and the checkout equipment of the design valve that can adapt to different size carries out impermeability and detects.
Summary of the invention:
It is simple that the technical matters that the utility model solves provides a kind of use, and cost is lower, and is easy to operate, can be convenient to the bubble-tight device of valve detection in producing the nitrogen making machine workshop.
The technical scheme in the invention for solving the technical problem is: a kind of valve airtight detection apparatus comprises air lift pump, gas-holder, support and detection air cavity; Described air lift pump connects gas-holder by tracheae, and the other end of described gas-holder connects the detection air cavity by tracheae, is provided with the first retaining valve between described gas-holder and the detection air cavity, and a tensimeter is tightly connected above described gas-holder; Be provided with detection platform above described detection air cavity, the rear end of described detection air cavity also is provided with the second retaining valve; Offer pilot hole on the described detection platform, offer in the centre of described detection platform and detect mouth, this detection mouth communicates with the detection air cavity.
Further, during for convenient detection valve impermeability, be convenient to the fixing of valve, the number of described pilot hole has two at least.
Further, the number of described pilot hole is four, and these four pilot holes are along the center array distribution of detection platform.
The beneficial effects of the utility model are: this device simplicity of design, and easy to operate, practical, applicable to the impermeability detection of plurality of specifications valve on the nitrogen making machine.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the synoptic diagram of detection platform in the utility model;
Fig. 3 is the valve synoptic diagram.
Among the figure: 1, air lift pump 2, tracheae 3, tensimeter 4, gas-holder 5, the first retaining valve 6, support 7, detection air cavity 8, detection platform 81, pilot hole 82, detection mouthful 9, second retaining valve 10, valve.
Embodiment:
A kind of valve airtight detection apparatus shown in Fig. 1～3 comprises air lift pump 1, gas-holder 4, support 6 and detects air cavity 7 that described gas-holder 4 and detection air cavity 7 all are arranged on support 6 tops; Described air lift pump 1 connects gas-holder 4 by tracheae 2, and the other end of described gas-holder 4 connects detection air cavity 7 by tracheae, is provided with the first retaining valve 5 between described gas-holder 4 and the detection air cavity 7, and a tensimeter 3 is tightly connected above described gas-holder 4; Be provided with detection platform 8 above described detection air cavity 7, the rear end of described detection air cavity 7 also is provided with the second retaining valve 9; Offer pilot hole 81 on the described detection platform 8, offer in the centre of described detection platform 8 and detect mouth 82, this detection 82 communicates with detection air cavity 7.
Further, during for convenient detection valve 10 impermeability, be convenient to the fixing of valve 10, the number of described pilot hole 81 has two at least.
Further, the number of described pilot hole 81 is four, and these four pilot holes 81 are along the center array distribution of detection platform 8.
At first close the first retaining valve 5, by air lift pump 1 to a certain amount of gas of gas-holder 4 interior injections, at this moment, close the second retaining valve 9, valve 10 is placed on the detection platform 8, behind the pilot hole location, guarantees that the door core of valve is aimed at detection mouth 82, then, open the first retaining valve 5, the numerical value on the tensimeter 3 remains unchanged, and formally the impermeability of this valve 10 is good, noly know that the valve impermeability is bad; Then, close the first retaining valve 5, open the second retaining valve 9, bleed off the gas that detects in the air cavity 7, take down this valve, change next valve, detect according to above-mentioned steps.This device simplicity of design, easy to operate, practical, applicable to the impermeability detection of plurality of specifications valve on the nitrogen making machine.
It is emphasized that, it more than is better implementation column of the present utility model, be not that utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
