Description
Technical field
This utility model belongs to detection design field, more particularly, to the portable airtight detector of one kind.
Background technology
Different clients require difference for the air-tightness of different confined spaces, and traditional airtightness measurement is by artificially will
Pressure in confined space increases to the pressure of needs, outer airtight to judge by the change of sight glass U-tube in confined space
The air-tightness in space.Pressure is not easily controlled as supercharging is artificially carried out to airtight space, carries inconvenient, accuracy of detection difference etc.
Reason, its application are restricted.Therefore, research and development one kind is easy to carry, the accurate airtight detector of easy to use, detection is one
Problem demanding prompt solution.
The content of the invention
In view of this, this utility model is directed to a kind of accurate portable airtight detector of easy to use, detection, with
Realization is detected to the air-tightness in confined space.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of portable airtight detector, including air pump, electromagnetic valve, airtight quantifier, external relay, switch, power supply,
Upper limit display lamp and lower limit display lamp, the air pump are connected with airtight space to be detected by electromagnetic valve, are that airtight space increases
Pressure, has two groups of solid-state relays, respectively the upset of control pressure upper and lower limit value signal, the power supply in the airtight quantifier
It is connected with the external relay by switch, the external relay is also indicated with the air pump, electromagnetic valve and the upper limit respectively
Lamp is connected, and external relay control electromagnetic valve is opened, and is pressurized for airtight space by electromagnetic valve by air pump, the airtight quantifier
It is connected with the external relay and lower limit display lamp respectively, when pressure reaches setting higher limit, triggers automatically airtight metering
The higher limit signaling switch of device internal solid relay, external relay are closed, solenoid closure so that ambient pressure and airtight sky
Interior pressure isolation, while air pump shuts down, upper limit display lamp is bright；When pressure drops to lower limit, airtight quantifier internal control
The solid-state relay signal automatic turning of lower limit processed, lower limit display lamp are bright, count by recording the time that pressure reaches upper and lower limit
Calculate the air-tightness in the space.
Further, the power supply output 24V unidirectional currents are powered for this portable airtight detector.
Further, described airtight quantifier mainly includes that differential pressure indicator, piezometer, pressure gauge, vacuometer, pressure become
Send device etc..
Relative to prior art, portable airtight detector described in the utility model has the advantage that：This airtight inspection
Instrument is surveyed using automatically controlling, upper pressure limit value can be pressurized to confined space accurately, while upper limit display lamp is bright, be worked as pressure drop
It is bright to lower limit display lamp during lower limit, the air-tightness of airtight space is calculated by recording the time used, it is not necessary to when people is long
Between monitoring observing the change of pressure, while this portable airtight detector integrates supercharging and measures, be easy to carry, replacement
It is former by the way of glass U-tube is measured；Have the advantages that simple structure, easy to use, detection data are accurate.
Description of the drawings

Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in this utility model can
To be mutually combined.
Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.
As shown in figure 1, a kind of portable airtight detector, including air pump 1, electromagnetic valve 2, airtight quantifier 3, external relay
Device 4, switch, power supply 5, upper limit display lamp 6 and lower limit display lamp 7, the air pump 1 pass through electromagnetic valve 2 and airtight sky to be detected
Between 8 be connected, be that airtight space 8 is pressurized, have two groups of solid-state relays in the airtight quantifier 3, respectively control pressure upper and lower limit
The upset of value signal, the power supply output 24V unidirectional currents are powered for this portable airtight detector, and the power supply 5 is by switch
Be connected with the external relay 4, the external relay 4 also respectively with the air pump 1,6 phase of electromagnetic valve 2 and upper limit display lamp
Even, the airtight quantifier 3 is connected with the external relay 4 and lower limit display lamp 7 respectively.Described airtight quantifier is main
Including differential pressure indicator, piezometer, pressure gauge, vacuometer, pressure transmitter etc..
The course of work of this example：The upper limit value and lower limit value of pressure, activate switch SR can be manually set during use, power supply 5 is
Whole machine is powered, and the now control of external relay 4 electromagnetic valve 2 is opened, and is pressurized for airtight space 8 by electromagnetic valve 2 by air pump 1, when
When pressure reaches setting higher limit, the higher limit signaling switch of 3 internal solid relay of airtight quantifier, external relay are triggered automatically
Device 4 cuts out, and electromagnetic valve 2 is closed so that pressure isolation in ambient pressure and airtight space 8, while air pump 1 shuts down, the upper limit
Display lamp 6 is bright；When pressure drops to lower limit, the solid-state relay signal automatic turning of control lower limit in airtight quantifier 3,
Lower limit display lamp 7 is bright, and the air-tightness in the space is calculated by recording the time that pressure reaches bound.
