Abstract

A kind of air-valve leakage test device, comprise air compressor machine, air compressor machine is connected with gas-holder, tensimeter and safety valve are housed on gas-holder, gas-holder is connected with the left chamber of tested valve by pipeline, on the pipeline between gas-holder and the left chamber of tested valve, variable valve and flowmeter is installed successively, on tested valve, pressure transducer is installed, the right chamber of tested valve is communicated with atmosphere by pipeline, and stop valve and pipeline sound suppressor are housed on the pipeline that the right chamber of tested valve is communicated with atmosphere successively.The beneficial effects of the utility model are: can know the leakage rate of tested valve under authorised pressure by reading the numerical value of glass rotors flow; Proving installation is Open architecture, goes for the valve of polymorphic type, many specifications, changes conveniently highly versatile.

Description

A kind of air-valve leakage test device
Technical field
The utility model relates to a kind of proving installation, particularly relates to the leakage test device of a kind of ventilating system valve.
Background technology
The valve that ventilating system is used rises while cutting off airflow function in system, and its leakage rate is had to certain requirement, and the leakage rate that system designer need grasp selected air-valve is accurately beneficial to determining of systematic parameter.The value of judging leakage rate in prior art is all by observing the calibration method of the non-physical quantities such as variation of gauge hand, and data are inaccurate and may cause erroneous judgement.
Summary of the invention
In order to overcome the inaccurate shortcoming of existing proving installation test data, it is a kind of convenient, fast and can directly read the air-valve leakage test device of leakage rate that the utility model provides.
It is a kind of air-valve leakage test device that the utility model solves the technical scheme that its technical matters adopts, comprise air compressor machine, air compressor machine is connected with gas-holder, tensimeter and safety valve are housed on gas-holder, gas-holder is connected with the left chamber of tested valve by pipeline, on pipeline between gas-holder and the left chamber of tested valve, variable valve and flowmeter are installed successively, on tested valve, pressure transducer is installed, the right chamber of tested valve is communicated with atmosphere by pipeline, and stop valve and pipeline sound suppressor are housed on the pipeline that the right chamber of tested valve is communicated with atmosphere successively.
Flow is counted glass rotameter.
The beneficial effects of the utility model are:
1, can know the leakage rate of tested valve under authorised pressure by reading the numerical value of glass rotameter, data are accurate, and reliability is high;
2, this proving installation is Open architecture, goes for the valve of polymorphic type, many specifications, changes conveniently highly versatile.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural map of the present embodiment;
In figure: 1. air compressor machine; 2. tensimeter; 3. safety valve; 4. gas-holder; 5. variable valve; 6. flowmeter; 7. pressure transducer; 8. tested valve; 9. stop valve; 10. pipeline silencer.
Embodiment
As shown in Figure 1, a kind of air-valve leakage test device, comprise air compressor machine 1, air compressor machine 1 is connected with gas-holder 4, tensimeter 2 and safety valve 3 are housed on gas-holder 4, gas-holder 4 is connected with the left chamber of tested valve 8 by pipeline, on pipeline between gas-holder 4 and the left chamber of tested valve 8, variable valve 5 and flowmeter 6 are installed successively, flowmeter in the present embodiment is selected glass rotameter, also can be other forms of flowmeter, on tested valve 8, pressure transducer 7 is installed, the right chamber of tested valve 8 is communicated with atmosphere by pipeline, on the pipeline that the right chamber of tested valve 8 is communicated with atmosphere, stop valve 9 and pipeline sound suppressor 10 are housed successively.
Original state, variable valve 5, stop valve 9 are all in closed condition, and tested valve 8, in closed condition, is opened air compressor machine 1, makes to be full of in gas-holder 4 pressurized air of set pressure.
When test, first open and adjust the aperture of variable valve 5, make pressurized air be full of test macro and make pressure remain on setting, open again stop valve 9, the right chamber of tested valve 8 and atmosphere are connected, continue to adjust the aperture of variable valve 5, guarantee that the pressure reading value of pressure transducer 7 is in constant setting, now the reading value of flowmeter 6 is the leakage rate of tested valve 8 under authorised pressure.

Claims (2)

1. an air-valve leakage test device, comprise air compressor machine, air compressor machine is connected with gas-holder, tensimeter and safety valve are housed on described gas-holder, it is characterized in that: described gas-holder is connected with the left chamber of tested valve by pipeline, on pipeline between described gas-holder and the left chamber of tested valve, variable valve and flowmeter are installed successively, on described tested valve, pressure transducer is installed, the right chamber of described tested valve is communicated with atmosphere by pipeline, on the pipeline that the right chamber of described tested valve is communicated with atmosphere, stop valve and pipeline sound suppressor is housed successively.
