To achieve the above object, the technical solution adopted in the present invention is：
A kind of shared multichannel leakage tester of gas/liquid, including airtight instrument, fixture, left side cylinder pressure, right side cylinder pressure, upper cylinder pressure, hydraulic station
With three air filters, airtight instrument all the way by the air inlet of the first Y-valve of piping connection, distinguish by two gas outlets of the first Y-valve
By two air inlets of the second Y-valve of piping connection, left examination that a gas outlet of the second Y-valve passes through piping connection fixture inside left
Leak chamber, the right leak test chamber that another gas outlet passes through piping connection fixture inner right side；Airtight instrument another way passes through piping connection three
The gas outlet for joining the gas outlet and the first Y-valve of air filter, when product is low pressure leak test, fixture uses common or low height
Pressure（≤0.8MPa）Gas blocks, and gas supply air source passes through piping connection atmospherically cylinder pressure all the way after three air filters
Electromagnetic valve air inlet, atmospherically cylinder pressure electromagnetism valve air gate be located at the upper cylinder pressure above fixture by piping connection；Second tunnel is logical
Piping connection air pressure side pressure cylinder electromagnetic valve air inlet is crossed, two gas outlets of air pressure side pressure cylinder solenoid valve are separately connected position by pipeline
Cylinder pressure and right side cylinder pressure on the left of fixture both sides；When product is high pressure leak test, cylinder pressure electromagnetic valve outlet on the hydraulic pressure of hydraulic station
By cylinder pressure in piping connection, two outlets of the hydraulic pressure side pressure cylinder solenoid valve of hydraulic station are separately connected the left side of fixture by pipeline
Cylinder pressure and right side cylinder pressure.
Preferably, the gas outlet of three air filters gets cylinder solenoid valve ready by piping connection, gets cylinder electromagnetism ready
Valve air gate gets cylinder ready by piping connection.
Preferably, the gas outlet of three air filters passes through one spare air pressure side pressure cylinder solenoid valve of piping connection.
Preferably, redundant hydraulic side pressure cylinder solenoid valve on hydraulic station.
Compared with prior art, it is an advantage of the invention that：
1, different product is not required to independent leak test board, only needs to change fixture and can be used, not only reduces leak test board, also save
Place；
2, it does not need high pressure air pump and is provided for a long term >=1.1MPa compressed airs, air feed equipment can be reduced, save production cost（Equipment
Expense, electricity charge etc.）；
3, production efficiency is improved, ensure that leak test product quality.
