Abstract
The invention relates to a leak detector, in particular to a leak detector of a sealed space leakage. An air inlet joint port is connected with a flowmeter, the flowmeter is connected with a three-way control valve, and the three-way control valve is connected with an air outlet joint port. The leak detector of the sealed space leakage can not only detect whether a tested system leaks or not and leakage rate by using compressed gas, but also can position a leakage point accurately by using fluorescent smoke, and thus a user is enabled to adjust and use according to an actual demand. Not only are the demands that whether leakage exists or not is tested and the leakage rate is tested met, but also the test demand that the leakage point is confirmed is met. The test functions can be realized on the same machine, and can be switched at any time, and thus different demands of a client can be met effectively.
Description
Technical field
The present invention relates to a kind of leak locator, relate in particular to the leak locator that a kind of confined space leaks.
Background technology
Existing measuring technology, whether can only testing of having leaks, and can't the test for leaks amount, and some can the test for leaks amount, but can't find out leakage point, can't satisfy the different demands of different clients under different situations.
Summary of the invention
The present invention is directed to the leak locator that above-mentioned deficiency provides a kind of confined space to leak.
The present invention adopts following technical scheme:
The leak locator that a kind of confined space of the present invention leaks comprises intake interface, flowmeter, three-way control valve, the interface of giving vent to anger; Described intake interface connection traffic meter, flowmeter connecting tee variable valve, three-way control valve connects the interface of giving vent to anger.
The leak locator that confined space of the present invention leaks also comprises the staving of fluorescence smog, the staving of the connection fluorescence smog of described three-way control valve, and the staving of fluorescence smog is connected to and picks out on the gas interface.
Beneficial effect
Whether the leak locator that confined space provided by the invention leaks can use pressure gas test system under test (SUT) to leak and leakage rate, can use again fluorescence smog accurately to locate leakage point; Make the user adjust use according to actual demand.Both can satisfy whether test leaks and the requirement of leakage rate, can satisfy again the test request of determining leakage point, and realize above-mentioned test function on same equipment, and can switch at any time, can effectively satisfy the different demand of client.
Gas line design of the present invention is ingenious, and two kinds of test patterns share same source of the gas and gas outlet, need not exchange gas source or gas outlet in test, can switch between fluorescence smog pattern and pressure gas pattern, and not affect test result.
Description of drawings
Fig. 1 is structural representation of the present invention;
In figure, 1 is intake interface, the 2nd, and flowmeter, the 3rd, three-way control valve, the 4th, the staving of fluorescence smog, the 5th, the interface of giving vent to anger.
Embodiment
The present invention is described in more detail below in conjunction with accompanying drawing:
As shown in the figure: the leak locator that a kind of confined space leaks comprises intake interface 1, flowmeter 2, three-way control valve 3, the staving 4 of fluorescence smog, the interface 5 of giving vent to anger; Described intake interface 1 connection traffic meter 2, flowmeter 2 connecting tee variable valve 3, three-way control valve 3 connects the interface 5 of giving vent to anger.The staving 4 of the connection fluorescence smog of three-way control valve 3, the staving 4 of fluorescence smog is connected to and picks out on gas interface 5.
Pressure gas enters from intake interface 1, flows through flowmeter 2, then arrives three-way control valve 3, and during in the pressure gas pattern, gas will arrive systems under test (SUT) through the interface 5 of giving vent to anger when variable valve 3, and flowmeter 2 can show whether system under test (SUT) leaks and leakage rate.Under another kind of pattern, three-way control valve 3 is rotated to fluorescence smog test pattern, gas will flow to the staving 4 that produces fluorescence smog, after the reaction in staving, fluorescence smog will be from the gas outlet 5 enters system under test (SUT), whether flowmeter will demonstrate system under test (SUT) and leak and leakage rate, and stay the fluorescence vestige at the leak place of system under test (SUT), use the UV irradiation to find easily.
Whether the present invention can use pressure gas test system under test (SUT) to leak and leakage rate, can use again fluorescence smog accurately to locate leakage point; Make the user adjust use according to actual demand.Two kinds of test patterns share same source of the gas and gas outlet, need not exchange gas source or gas outlet in test, can switch between fluorescence smog pattern and pressure gas pattern, and not affect test result.
The present invention both can satisfy whether test leaks and the requirement of leakage rate, can satisfy again the test request of determining leakage point, realized above-mentioned test function on same equipment, and can switch at any time, can effectively satisfy the different demand of client.
