Screw thread clip I (7) bottom end mesoporous is screwed together；
The clamping plate III (13), clamping plate IV (14) docking, dock in rear plate III (13) intermediate semicircle orifice and clamping plate IV (14)
Between the circular hole that constitutes of semicircle orifice cover on the interface C of respiratory siphon (10), in docking rear plate III (13) and clamping plate IV (14) two
Below side, one piece of snap-gauge III (11) and one piece of snap-gauge IV (12) are clamped respectively, two double threaded screw (28) upper ends difference are successively
The circular hole and snap-gauge III (11) mesoporous III (11-1) and snap-gauge IV of insertion docking rear plate III (13) and clamping plate IV (14) two sides
(12) clamping plate III (13) and clamping plate IV (14) are fixed on snap-gauge III (11) and snap-gauge IV (12) by nut by mesoporous IV (12-1)
On, welding point (2) upper end is screwed together with screw thread clip I (7) bottom end mesoporous,
Threaded Connector Coupling (27) other end is screwed together with screw thread clip II (15)；
Second step, determines counterweight, and counterweight (33) is determined according to the force request conversion for being detected interface, by formula G=T ×
(Z1/Z2) it converts, G is balance weight, and T is detected jointing requirements by strength, and Z1 is minor sprocket (36) number of teeth, and Z2 is big
Sprocket wheel (34) number of teeth, the effect of counterweight (33) are exactly to connect first fixed force to detected；
Third step, starts air compressor, and compressed air passes sequentially through the suppress pipe (26) of air compressor and to Threaded Connector Coupling
(27) it injects in tens of rice or hundreds of meters of detected respiratory siphons (10), the pressure of gas is typically all the requirement by client, than
If any requirement 20bar, some requirement 30bar, section between 0-250bar in, close the valve on suppress pipe (26), ten
Five minutes to three ten minutes later, observe the pressure gauge air pressure that is connect with suppress pipe (26) have it is unchanged, if pressure gauge air pressure is without change
Change, illustrates the interface A connecting with tens of rice or hundreds of meters of detected respiratory siphons (10) or interface B or interface C or interface D without leakage
Gas occurs, and shows detected respiratory siphon (10) qualification；
If pressure gauge air pressure becomes smaller, illustrate the interface A or interface B connecting with tens of rice or hundreds of meters of detected respiratory siphons (10)
Or interface C or interface D have gas leakage, further check
I (7) upper end mesoporous of respiratory siphon (10) screw thread clip, which is inserted in, to be made up of necking machine necking behind conic connector I (8) bottom end
Interface A whether do not connect gas leakage or respiratory siphon (10) Single port I (10-1) insertion compression joint I (9) and conic connector I (8) it
Between after the interface B that is made up of necking machine necking whether do not connect gas leakage or screw thread clip II (15) upper end mesoporous is inserted in the conical surface
Whether the interface C being made up of behind connector II (16) bottom end necking machine necking does not connect the another port of gas leakage or respiratory siphon (10)
Whether the rear interface D being made up of necking machine necking between II (10-2) insertion compression joint II (17) and conic connector II (16)
Gas leakage is not connected, detects the interface of gas leakage, shows that detected respiratory siphon (10) is unqualified.
