Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of leak detection simple, and location leak source accurate valve leak detection proving installation.
The purpose of this utility model realizes by following technical proposal: a kind of valve leak detection proving installation, comprise testing flume, it is characterized in that: also comprise draft tube and escape pipe, draft tube one end is connected with air pump, draft tube other end end and end, escape pipe one end are respectively equipped with web member one and web member two, also comprise valve to be checked, described valve entirety to be checked is placed in testing flume, valve inlet to be checked and valve export to be checked are tightly connected with web member one and web member two respectively, and make draft tube, escape pipe is communicated with the valve pocket of valve to be checked, described draft tube and escape pipe are respectively equipped with principal pressure table and secondary stress table, described draft tube and escape pipe are also respectively equipped with gas admittance valve and air outlet valve.
Valve inlet to be checked and valve export to be checked are tightly connected with web member one and web member two respectively, when detection leaks outside, open valve to be checked and gas admittance valve, close air outlet valve, by air pump toward draft tube and escape pipe and valve interacvity air-filling, close gas admittance valve afterwards, by whether occurring in testing flume whether bubble and principal pressure table and secondary stress table change can intuitive judgment whether leak outside, if leak outside, then close valve to be checked, if principal pressure gauge pressure diminishes and secondary stress gauge pressure is constant, then can judge that valve inlet side to be checked leaks outside; In like manner or valve export side to be checked leak outside; When leaking in detection, close air outlet valve and valve to be checked, open gas admittance valve and inflate, closing gas admittance valve afterwards, whether changed by secondary stress gauge pressure and can judge the whether interior leakage of valve to be checked.Therefore this device can simply judge interior leakage and leak outside, and can general locating leaks point.
As preferably, described web member one and web member two are threaded with valve inlet to be checked and valve export to be checked respectively.
Be threaded connection and make better tightness, it is more accurate to test.
As preferably, described web member one and web member two are respectively inlet flange sheet and flange plate of giving vent to anger.
Make to be connected more rapid by inlet flange sheet and flange plate of giving vent to anger, detection efficiency is high.
As preferably, described inlet flange sheet and flange plate of giving vent to anger are respectively equipped with O-ring seal, and described O-ring seal can offset with valve inlet to be checked and outlet and be sealed into tracheae and valve pocket and escape pipe and valve pocket respectively.
Better tightness is made by O-ring seal.
Compared with prior art, the utility model tool has the following advantages:
Valve inlet to be checked and valve export to be checked are tightly connected with web member one and web member two respectively, when detection leaks outside, open valve to be checked and gas admittance valve, close air outlet valve, by air pump toward draft tube and escape pipe and valve interacvity air-filling, close gas admittance valve afterwards, by whether occurring in testing flume whether bubble and principal pressure table and secondary stress table change can intuitive judgment whether leak outside, if leak outside, then close valve to be checked, if principal pressure gauge pressure diminishes and secondary stress gauge pressure is constant, then can judge that valve inlet side to be checked leaks outside; In like manner or valve export side to be checked leak outside; When leaking in detection, close air outlet valve and valve to be checked, open gas admittance valve and inflate, closing gas admittance valve afterwards, whether changed by secondary stress gauge pressure and can judge the whether interior leakage of valve to be checked.Therefore this device can simply judge interior leakage and leak outside, and can general locating leaks point.
