Description
Technical field
The utility model belongs to air-tightness detection device technical field more particularly to a kind of air-conditioned cold store air-tightness quickly detects
Device.
Background technology
Air-tightness is the very important index of air-conditioned cold store, and air-tightness does not reach requirement, and gas can not be just realized in air-conditioned cold store
The control of ingredient.Newly-built air-conditioned cold store is required for carrying out air-leakage test, if reaches air-tightness requirement index, the use of air-conditioned cold store
In, every certain time is also required to carry out air-leakage test and be repaired, and air-leakage test is cumbersome, library is carried out
Air pressurized seals the library, the time that the pressure being detected with the use of manometer in library declines, measures under volume pressure
Half dip time, detection it is time-consuming and laborious, efficiency is low.
In conclusion problem of the existing technology is：The air-leakage test of air-conditioned cold store is cumbersome, library is carried out empty
Gas pressurizes, and seals the library, the time that the pressure being detected with the use of manometer in library declines, measures under volume pressure
Half dip time, detection is time-consuming and laborious, and efficiency is low.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of air-conditioned cold store air-tightness device for fast detecting.
The utility model is realized in this way a kind of air-conditioned cold store air-tightness device for fast detecting is provided with detection interface, institute
State detection interface and air-conditioned cold store connected by the first valve, the rear end of the detection interface by the second valve communication with detection instrument and
Solenoid valve and air pump；
Pressure gauge, the rear end connection gas of the solenoid valve are installed on the connecting line of the detection interface and solenoid valve
Pump.
Further, the connecting tube uses hose or hard tube.
Further, the pressure gauge is using instrument differential manometer or electronic sensor pressure gauge or tilting hydraulic gage.
The advantages of the utility model and good effect are：The air-conditioned cold store air-tightness device for fast detecting can quickly connect gas
Adjust the reserved connector in library, you can realize quick detection, connecting tube can quickly be connected with hose or hard tube, and pressure gauge can use instrument
Table differential manometer, it is also possible to electronic sensor pressure gauge, it is also possible to which tilting hydraulic gage, detection can also may be used with the manual record time
With automatic data collection.
Description of the drawings
Fig. 1 is the structure diagram for the air-conditioned cold store air-tightness device for fast detecting that the utility model embodiment provides；
In figure：1st, air-conditioned cold store；2nd, the first valve；3rd, interface is detected；4th, the second valve；5th, pressure gauge；6th, solenoid valve；7th, gas
Pump.
Specific embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing.
The structure of 1 pair of the utility model is explained in detail below in conjunction with the accompanying drawings.
The air-conditioned cold store air-tightness device for fast detecting is provided with detection interface 3, and the detection interface 3 passes through the first valve 2
Air-conditioned cold store 1 is connected, the rear end of the detection interface 3 connects solenoid valve 6 by the second valve 4；
The detection interface 3 is with being equipped with pressure gauge 5, the rear end connection of the solenoid valve 6 on the connecting line of solenoid valve 6
Air pump 7.
As the preferred embodiment of the utility model, the connecting tube uses hose or hard tube.
As the preferred embodiment of the utility model, the pressure gauge 5 uses instrument differential manometer or electronic sensor pressure
Meter or tilting hydraulic gage.
The operation principle of the utility model is：After detection device is connect with air-conditioned cold store 1, first valve 2 and the are opened manually
Two valves 4 start air pump 7, while make solenoid valve 6 and 7 synchronous start and stop of air pump by controller, inflate, add to air-conditioned cold store 1
Be pressed onto as defined in slightly above detection after rated value, stop air pump 7, being simultaneously stopped solenoid valve 6 makes its closing, make detection instrument and
Air-conditioned cold store 1 keeps connection status, and at this moment the pressure of pressure gauge is begun to decline, when pressure drops to specified duty pressure as defined in detection
The change value of pressure of start recording pressure gauge 5 and time, when pressure drops to rated value half, the required time is air-conditioned cold store half
Dip time.
The reserved connector of air-conditioned cold store 1 can quickly be connected, you can realize quick detection, connecting tube can use hose or hard tube
Quick connection, 5 table of pressure gauge can use instrument differential manometer, it is also possible to electronic sensor pressure gauge, it is also possible to tilting hydraulic gage, inspection
Survey can be with the manual record time, can also automatic data collection.
The above is only the preferred embodiment to the utility model, and not the utility model is made in any form
Limitation, it is every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, belongs in the range of technical solutions of the utility model.
