Background technology
In construction, especially industrial building construction, many valves can be related to, since valve size differs, and
Do not know whether valve air-tightness is qualified, need to carry out the selective examination detection of valve air-tightness when marching into the arena, existing detection method is to face
When make caliber and water tank pressure testing, not only detection time is long, but also detects operating difficulties.
Invention content
The object of the present invention is to provide a kind of valve air-tightness detection methods, this method detection range is wide, detection efficiency is high,
Easy to operate, detection is accurately.
The technical solution adopted in the present invention is：
A kind of valve air-tightness detection method：Before detection, water tank is set, water tank lower part is connected with suppressing water pump, suppresses water
Pump is equipped with pressure gauge, and tank top is connected with exhaust pipe, and exhaust pipe is equipped with air bleeding valve, and water tank side is examined respectively with several
Test tube connects, and ball valve and pressure gauge are equipped in detection pipe, and detection pipe end is respectively equipped with the flange of different tube diameters；During detection,
Valve to be detected is installed on the flange of corresponding caliber, opens air bleeding valve, open in the blue place detection pipe of corresponding diameter Method
Ball valve closes remaining ball valve, and water pump is suppressed in startup to be made water be completely filled with water tank and maintain, and is suppressed thereafter through comparison and is pressed on water pump
The numerical value of pressure gauge judges the air-tightness of valve to be detected in detection pipe where the numerical value of power table and corresponding diameter Method are blue.
Further, water tank bottom is equipped with castor.
Further, the caliber of flange is respectively DN100, DN150, DN200, DN250, DN300 and DN400.
The beneficial effects of the invention are as follows：
The flange of different tube diameters can correspond to different valves to be detected, that is, an equipment can detect various types of
