Abstract
The invention discloses a double-station airtightness tester and particularly relates a device applied to an airtightness pressure test of a cast pipe. The double-station airtightness tester comprises a lifting rack, wherein a lifting oil cylinder is fixed to the lifting rack; the piston rod of the lifting oil cylinder is connected to a main beam which is capable of moving up and down along the lifting rack; a bracket is horizontally arranged below the main beam; the bracket and the main beam are connected through a bell-end retaining wall and a jack retaining wall; a pushing oil cylinder is horizontally fixed to the bell-end retaining wall; a bell end suppressing plug is mounted on the piston rod end of the pushing oil cylinder; and a jack suppressing plug coaxial with the bell end suppressing plug is arranged on the jack retaining wall. The tester is characterized in that two bell end suppressing plugs and two jack suppressing plugs are respectively arranged horizontally. The double-station airtightness tester can test two cast pipes at a time, so that the productivity is improved.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
Shown in Figure 1, the present invention includes lifting frame 10, fixing elevating ram 1 on the lifting frame 10, the piston rod of elevating ram 1 connects the girder 7 that can move up and down along lifting frame, girder 7 lower horizontal are provided with carriage 8, be connected with socket barricade 6 by bellmouth barricade 4 between carriage 8 and the girder 7, horizontal fixed pipe bending cylinder 3 on the bellmouth barricade 4, pipe bending cylinder 3 tailpieces of the piston rod are installed bellmouth and are suppressed plug, be provided with on the socket barricade and suppress the coaxial socket of plug with bellmouth and suppress plug, described bellmouth is suppressed plug and socket and is suppressed plug and be horizontally disposed with two respectively.
Described bellmouth is suppressed plug and is connected the guide pole 11 parallel with pipe bending cylinder 3.
Described elevating ram 1 is arranged on girder 7 belows.
Connect angle sheave on the described girder 7, the angle sheave wheel face is fitted with the vertical channel-section steel outer rim that is welded on the lifting frame 7, monolateral four angle sheaves is set.
Plug suppressed by described socket and bellmouth is suppressed the fixed installation of plug by location, axial accurately seat hole.
Suppress the plug back in described socket Rubber washer is set.
Described girder adopts the welding of 20mm steel plate.
Described socket barricade and bellmouth barricade are welded by steel plate.
The equipment work flow process is as follows: the post worker is risen elevating ram 1, make the rotation support roller 2 on plane on no drive track, plane equal, the pressure testing cast tube is rolled into above the rotation support roller 2, pipe bending cylinder 3 advances, and makes bellmouth suppress the O-ring seal of plug and O-ring seal that socket is suppressed plug and lives the pressure testing cast tube is sealed at both ends.Elevating ram 1 falls, and after cast tube falls into the water fully, opens the nitrogen valve, after the pipe internal pressure is also stablized to authorised pressure, and time pressurize according to the rules, whether have bubble emerge, check the impermeability of pressure testing cast tube if observing in the water.Airtight qualified, open air release, gas in the releasing tube.Elevating ram 1 rise is put in place, pipe bending cylinder 3 retreats, making bellmouth suppress plug and socket suppresses the O-ring seal of plug and breaks away from the pressure testing cast tube, then with two cast tube Rotate 180 degree, the secondary pressure testing: bellmouth pipe bending cylinder 3 advances, and makes bellmouth suppress plug O-ring seal and socket and suppresses the plug O-ring seal and live the pressure testing cast tube is sealed at both ends.Elevating ram 1 falls, and after cast tube falls into the water fully, opens the nitrogen valve, after the pipe internal pressure is also stablized to authorised pressure, and time pressurize according to the rules, whether have bubble emerge, check the impermeability of pressure testing cast tube if observing in the water.Airtight qualified, open air release, gas in the releasing tube.Elevating ram 1 rise is put in place, and pipe bending cylinder 3 retreats, and makes bellmouth and spigot seal circle break away from the pressure testing cast tube, and the pressure testing cast tube is rolled out rotation support roller 2 on no drive track, and pressure testing is finished.
