Description
Technical field
The utility model relates to detection technique field, is specifically related to a kind of air-tightness detection device.
Background technology
At present, manometer is produced and all will be carried out impermeability detection, and object is the impermeability that checks all parts cooperation of manometer, and whether manometer has the phenomenon of gas leakage.Conventional detection method is exactly to connect in the draft tube of manometer the plug being connected with gas piping; By gas piping, the draft tube of manometer is carried out to plenum again, be then placed in water look into see if there is bubble overflow.In use there are the following problems for this detection mode:
The first, because testing process is all manual operation, need manually from water, manometer to be pulled out, in the time of cold day, water temperature is very low, and operation can make staff move discomfort for a long time, and when serious, both hands there will be pernio, and the person is worked the mischief; The second, manometer of every detection all will carry out the draft tube of manometer the plug of artificial sealing, is affected by human factors greatly, often occurs that the draft tube of manometer is because of the poor phenomenon that will reset of sealing, and labour intensity is large.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of air-tightness detection device, its object: do not make water detect impermeability, and a fixation pressure instrument.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of air-tightness detection device, comprises frame and is arranged on the board in frame, board is provided with source of the gas, pipeline, stationary installation and starting switch;
Stationary installation comprises substrate and locking mechanism, and described locking mechanism arranges on substrate, is provided with through hole in substrate, and one end of described through hole is provided with sealing adaptor, and the other end of through hole is connected with one end of pipeline, and the other end of pipeline is connected with source of the gas;
On pipeline, be provided with successively solenoid valve and datum pressure instrument;
Locking mechanism comprises supporting member and spanner, and spanner is provided with the fastener corresponding with sealing adaptor;
Starting switch is electrically connected with source of the gas and solenoid valve.
Preferably, the working end of sealing adaptor is provided with O-ring seal and connects head, and connecting the lateral wall of head and the angle of vertical direction is 20～30 degree.
By technique scheme, by spanner and coordinating of sealing adaptor manometer to be measured being clamped, guarantee once fixing; And what detection resources adopted is source of the gas, and source of the gas provides the pressure of 1 MPa, whether remains on 1 MPa determine whether manometer to be measured leaks gas according to the numerical value on the numerical value of surveying of datum pressure instrument; And supplying gas and hold one's breath by solenoid control of this process, safe and reliable, avoid making water to detect impermeability.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of air-tightness detection device, comprises frame 1 and is arranged on the board 2 in frame 1, board 2 is provided with source of the gas 3, pipeline 4, stationary installation and starting switch 6; Stationary installation comprises substrate 51 and locking mechanism, described locking mechanism arranges on substrate 51, in substrate 51, is provided with through hole, and one end of described through hole is provided with sealing adaptor 511, the other end of through hole is connected with one end of pipeline 4, and the other end of pipeline 4 is connected with source of the gas 3; On pipeline 4, be provided with successively solenoid valve 41 and datum pressure instrument 42; Locking mechanism comprises supporting member 521 and spanner 522, and described spanner 522 is provided with the fastener corresponding with sealing adaptor 511 5221; Starting switch 6 is electrically connected with source of the gas 3 and solenoid valve 41.
Process and the effect of this pick-up unit are as follows:
First manometer to be measured is assigned into sealing adaptor 511, then spanner 522 is lifted, now the fastener 5221 on spanner 522 withstands on manometer to be measured, and manometer to be measured is clamped, and once fixing need not refitting, is convenient to fixing and dismounting.Press again starting switch 6, source of the gas 3 work and solenoid valve 41 are opened; In the time that internal pressure reaches the pressure of 1 MPa, starting switch 6 is upspring automatically, and source of the gas 3 and solenoid valve 41 power-off are closed automatically, whether remains on 1 MPa determine whether manometer to be measured leaks gas according to the numerical value on the numerical value of surveying of datum pressure instrument 42, security of operation, testing result is reliable.
As shown in Figure 3, the working end of sealing adaptor 511 is provided with O-ring seal 5111, has guaranteed not have between manometer to be measured and sealing adaptor 511 generation of leakage; The working end of described sealing adaptor 511 is also provided with and connects 5112, and connecting a lateral wall of 5112 and the angle of vertical direction is 20～30 degree, has further facilitated the fixing and dismounting of manometer to be measured.
Be exactly more than a kind of design feature and process effect of air-tightness detection device, its advantage: simple and practical, convenient to operation, one-time fix and need not reset, be convenient to fixing and dismounting; Security of operation, testing result is reliable, has avoided making water to detect impermeability.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
