Tubing pressure testing, sealing and pressure bearing system comprise and are arranged on the end socket on the master cylinder and are arranged on bearing on the horizontal oil cylinder, and the bottom of described master cylinder is arranged on the column, and described horizontal oil cylinder is separately positioned on up and down on the longeron.
A kind of pipe tester, the bottom of described stable cylinder is arranged on the water tank end face.
A kind of pipe tester, is stablized cylinder and carriage is two groups of devices that are symmetricly set on the jacking cylinder both sides at described guiding mechanism.
A kind of pipe tester, described end socket adopts bell and spigot frame, is provided with pressure ring, O-ring seal and hold-down bolt.
The invention has the advantages that:
1, solves the problem of heavy caliber pipe, plastic pipe, the whole pressure testing difficulty of composite material pipe effectively, and effectively reduced experimentation cost.
2, compare with existing metal pipe material pressure testing machine, inflow of the present invention is big, the pressure testing time is short, efficient is high, wide accommodation.
3, compare with existing plastic pipe pressure testing machine, the present invention has advantages such as test pressure height, end sealing be reliable.

Embodiment
Relevant technology contents of the present invention and detailed description, existing conjunction with figs. is described as follows:
As shown in Figure 1 and Figure 2, a kind of pipe tester of the present invention comprises:
(1) tubing support system:
This system is made up of column 1, longeron 2, water tank 3, and two ends column 1 usefulness longeron 2, water tank 3 are connected, thereby makes the pressure of tubing form self-equilibrating, has saved huge bracing or strutting arrangement.
(2) tubing holds up and positioning system:
This system comprises the guiding mechanism 5 that is arranged on jacking cylinder 4 both sides; Carriage 6 by described jacking cylinder 4 supports; Be arranged on the stable cylinder 7 of described carriage 6 bottoms; Be arranged on limit switch 8 and adjusting gear and relevant fluid power system on the described longeron 2; The bottom of stablizing cylinder 7 is arranged on water tank 3 end faces; Guiding mechanism 5, stablize cylinder 7 and carriage 6 for being symmetricly set on two groups of devices of jacking cylinder 4 both sides.
(3) tubing pressure testing, sealing and pressure bearing system:
This system is by end socket 9, master cylinder 10, bearing 11 and laterally oil cylinder 12 and the relevant gentle pressure-controlled equipment of fluid power system are formed; Wherein end socket 7 adopts bell and spigot frame, is provided with pressure ring, O-ring seal and hold-down bolt and has annexes such as exhausr port, feed water inlet, freeing port, tensimeter.
(4) tubing water system:
This system is made up of water tank 3, water pump 13, water supply line 14 and water-level control apparatus.
(5) tubing compression system:
This system is made up of high pressure gas holder 15, high-pressure air pipe 16, high pressure water pot 17, high-pressure water pipe 18 and air-path control system, wherein high-pressure air pipe 16 1 ends connect high pressure gas holder 15, the other end connects high pressure water pot 17, and high pressure water pot 17 is connected with high-pressure water pipe 18, and has annex such as tensimeter.
(6) other equipment:
Hydraulic Station 19: for jacking cylinder 4, master cylinder 10, bearing 11 and horizontal oil cylinder 12 provide power.
Switch board 20: tubing pressure testing process is carried out robotization control.
In practical operation, at first tubing is moved into pressure testing machine, a side is stablized cylinder 7 and is lifted, tubing enters from another survey, and then another is surveyed and stablize cylinder 7 and to lift, and treats that tubing is after the pressure testing ready position is located, the front and back end is stablized cylinder 7 and all is in the state of lifting, and carriage 6 forms V-structure, stablizes tubing; Then, jacking cylinder 4 elongations steadily hold up tubing under the control of guiding mechanism 5, and the tubing upside is contacted with limit switch 8, and this moment, the tubing axial line was just concentric with two ends end socket 9; Fluid power system stops to advance and keeping constant pressure, makes tubing be stabilized in the work pressure test position; Then two ends master cylinder 10 extends simultaneously, promotes two ends end socket 9 and seals the tubing end; Bearing 11 inserts between column 1 and the end socket 9 under the driving of horizontal oil cylinder 12 afterwards, and so during the tubing pressure testing, the interior pressure of tubing passes on the column 1 by end socket 9, bearing 11, avoids master cylinder 10 to bear huge test pressure; Start water pump 13 then, open exhausr port and make water can continue to enter body, in will managing after the fills with water, switch off the pump 13 and exhausr port; Gas in the high pressure gas holder 15 enters high pressure water pot 17 by pressure control valve afterwards, the water in the high pressure water pot 17 is pressed into tubing by the test pressure requirement, thereby tubing is boosted, until authorised pressure; Close high-pressure air pipe 16 road valves, high-pressure water pipe 18 road valves afterwards, open freeing port and make the water in the tubing return water tank 3, until with the water emptying in the tubing by drainpipe; Laterally oil cylinder 12 withdrawals are shifted out bearing 11 between end socket 9 and the column 1 then, and bearing sets back; Start master cylinder 10 afterwards, end socket 9 is set back, start jacking cylinder 4, it is set back, start and stablize cylinder 7, it is set back; At last tubing is shifted out pressure testing machine.
Above-mentioned is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention, and all equivalences of making according to patent claim of the present invention change and revise, and all are included in the claim of the present invention.
