Abstract
The invention relates to an air valve leakage test device. The air valve leakage test device comprise an air compressor; the air compressor is connected with an air storage tank; the air storage tank is provided with a pressure meter and a safety valve; the air storage tank is connected with the left cavity of a tested valve through a pipeline; a regulating valve and a flow meter which are located between the air storage tank and the left cavity of the tested valve are sequentially arranged on the pipeline; the tested valve is provided with a pressure sensor; the right cavity of the tested valve is communicated with atmosphere through a pipeline; and the pipeline communicated with the atmosphere and the right cavity of the tested valve is sequentially provided with a cut-off valve and a silencer. With the air valve leakage test device of the invention adopted, the leakage rate of the tested valve under prescribed pressure can be known by reading a numerical value of the glass rotameter. The test device is of an open structure and is suitable for valves in various types and specifications, easy to uninstall and replace, and high in universality.
Description
Technical field
The present invention relates to a kind of proving installation, particularly relate to a kind of leakage test device of ventilating system valve.
Background technology
When the valve of ventilating system rises in systems in which and cuts off airflow function, have certain requirement to its leakage rate, the leakage rate that system designer need grasp selected air-valve is accurately beneficial to the determination of systematic parameter.The value judging leakage rate in prior art is all by observing the calibration method of the non-physical quantities such as the 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, the invention provides a kind of convenient, fast and directly can read the air-valve leakage test device of leakage rate.
The technical solution adopted for the present invention to solve the technical problems is a kind of air-valve leakage test device, comprise air compressor machine, air compressor machine is connected with gas-holder, tensimeter and safety valve gas-holder be equipped with, gas-holder is connected with the left chamber of tested valve by pipeline, pipeline between gas-holder and the left chamber of tested valve installs variable valve and flowmeter successively, tested valve is provided with pressure transducer, the right chamber of tested valve is communicated with air by pipeline, and the pipeline that the right chamber of tested valve is communicated with air is equipped with stop valve and pipeline sound suppressor successively.
Flow counts glass rotameter.
The invention has the beneficial effects as follows:
1, the numerical value by reading glass rotameter can know the leakage rate of tested valve under authorised pressure, and 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.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
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 gas-holder 4 be equipped with, gas-holder 4 is connected with the tested left chamber of valve 8 by pipeline, pipeline between gas-holder 4 and the left chamber of tested valve 8 is installed successively variable valve 5 and flowmeter 6, glass rotameter selected by flowmeter in the present embodiment, also can be other forms of flowmeter, tested valve 8 is provided with pressure transducer 7, the tested right chamber of valve 8 is communicated with air by pipeline, the pipeline that the tested right chamber of valve 8 is communicated with air is equipped with stop valve 9 and pipeline sound suppressor 10 successively.
Original state, variable valve 5, stop valve 9 are all in closed condition, and tested valve 8 is in closed condition, opens air compressor machine 1, make the pressurized air being full of set pressure in gas-holder 4.
During 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 stop valve 9 again, the tested right chamber of valve 8 and air are connected, continue the aperture of adjustment 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 described gas-holder be equipped with, it is characterized in that: described gas-holder is connected with the left chamber of tested valve by pipeline, pipeline between described gas-holder and the left chamber of tested valve installs variable valve and flowmeter successively, described tested valve is provided with pressure transducer, the described right chamber of tested valve is communicated with air by pipeline, and the pipeline that the described right chamber of tested valve is communicated with air is equipped with stop valve and pipeline sound suppressor successively.
