Abstract
The invention relates to a pressure test tool, which detects the sealing property of a lateral wing outlet connection flange backing ring after a tubing head is arranged in field. The pressure test tool consists of a function lever, a pressure test end cap, a sealing ring, a handle and a pressure test joint, wherein the pressure test end cap is a solid body; the sealing ring is sleeved on the outer circumference of the front part of the pressure test end cap; external threads are reserved on the outer circumference of the middle part of the pressure test end cap, and are in threaded connection with an inner hole of a lateral wing outlet of the tubing head; a horizontal screw hole is reserved in the rear part of the pressure test end cap; the function lever is inserted into the screw hole; the external threads are reserved on the rear part of the function lever, and are screwed with the handle or sleeved with the pressure test joint; and a lock nut is screwed most outside the function lever to fixedly connect the handle and the function lever. The pressure test tool solves the problems on the detection of the sealing property of the lateral wing outlet connection flange backing ring after the tubing head is arranged in field, and ensures the safe use of a wellhead device and well control security.
Description
One, technical field: after the present invention relates to a kind of tubing head and installing at the scene, the pressure test tool that flank outlet joint flange gasket ring sealing property detects.
Two, background technology: tubing head send well to install and use after pressure testing detection is carried out in well control workshop, due to the sealing property that vibration is jolted and the link such as lifting operation may have influence on tubing head lateral wing outlet joint flange gasket ring at the scene in transit, its reliability can not guarantee completely, once occurred to cause gas blowout accident because tubing head lateral wing outlet joint flange gasket ring place thorn leaks in tubing flow displacement process, and left hidden danger to the safe handling of well head set-up.Three, summary of the invention: the object of the invention is to propose a kind of simple in structure, fitting operation is convenient and swift, cost is low, the pressure test tool after installing at the scene, tubing head lateral wing outlet joint flange gasket ring sealing property being detected.
The object of the present invention is achieved like this: tubing head lateral wing pressure test tool, by control lever, pressure testing plug, O-ring seal, handle and action pressure-testing joint composition, pressure testing plug is solid, on its anterior excircle, cover has O-ring seal, on the excircle of middle part, have the external thread being connected with tubing head lateral wing outlet inner hole thread, in rear portion, have the screw of level, in described screw, be plugged with control lever.Have external thread at control lever rear portion, on it, spin handle or socket action pressure-testing joint, lock nut is threaded onto control lever outermost, and handle is fixedly connected with control lever.
The invention solves tubing head the problem that posterior area of fixigena outlet joint flange gasket ring sealing property detects is installed at the scene, guaranteed safe handling and the well control safety of well head set-up.
Four, accompanying drawing explanation: concrete structure of the present invention is provided by following drawings and Examples:
Fig. 1 is the tubing head lateral wing pressure test tool schematic diagram that is connected with handle;
Fig. 2 is the tubing head lateral wing pressure test tool schematic diagram that is connected with action pressure-testing joint.
Legend: 1, pressure testing plug, 2, O-ring seal, 3, straight pin, 4, holding screw, 5, wiper block, 6, diversion trench, 7, control lever, 8, handle, 9, lock nut, 10, action pressure-testing joint, 11, vent hole, 12, plug, 13, pressure testing hole.
Five, embodiment:
The present invention is not subject to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
Embodiment: as shown in Figure 1-2, tubing head lateral wing pressure test tool is by control lever (7), and pressure testing plug (1), O-ring seal (2), handle (8) and action pressure-testing joint (10) form.Pressure testing plug (1) is solid, on its anterior excircle, cover has O-ring seal (2), on the excircle of middle part, have the external thread being connected with tubing head lateral wing outlet inner hole thread, in rear portion, have the screw of level, in described screw, be plugged with control lever (7).On the excircle at pressure testing plug (1) rear portion, interval 90 degree have pin-and-hole and screw hole, are inserted with respectively straight pin (3) and holding screw (4) in hole.On pressure testing plug (1) front end face circumference, be processed with chamfering.(7 is a solid stock to control lever, connecting end with pressure testing plug (1) is processed with and aforementioned pin-and-hole and corresponding circular hole and the threaded hole of screw hole, straight pin (3) is through in circular hole, and holding screw (4) end is screwed in threaded hole.Have external thread at control lever (7) rear portion, the handle that spins on it (8), lock nut (9) is threaded onto control lever, and (7 outermost are fixedly connected with handle (8) with control lever (7).Described lock nut (9) is nut.On control lever (7), also cover has wiper block (5), the right cylinder that wiper block (5) is hollow, the diversion trench (6) that has level on its block excircle, is fixed on control lever (7) by lock-screw.Wiper block (5) excircle is located except diversion trench (6), and remainder contacts with canalis pterygoideus inner wall sealing.In action pressure-testing joint (10), it is cavity, its one end is not sealed, another end sealing, on the outer wall of blind end, do not have the external thread being connected with thread flange, in blind end excircle, interval 90 degree are processed with two vent holes (11), plug (12) is installed in it, has the horizontal pressure testing hole (13) that connects pressure testing equipment in Closed End, described pressure testing hole (13) is communicated with action pressure-testing joint (10) internal cavity.
The flat valve being connected with tubing head is placed in to fully open position, the thread flange place that tubing head lateral wing pressure test tool is connected by flat valve outside is inserted in the through hole of tubing head lateral wing outlet, pressure testing plug (1) is screwed in the internal thread of tubing head body flank outlet by handle (8), after screwing and putting in place, dismantle lock nut (9), take off handle (8), again action pressure-testing joint (10) is placed on to control lever (7) rear end, and spins with thread flange.Test medium is injected in pressure testing hole (13) from action pressure-testing joint (10) in the canalis pterygoideus of tubing head lateral wing outlet, the plug (12) unloading in open pores (11) carries out exhaust, after gas drains, tighten plug (12), boost to the experimental pressure of designing requirement, tubing head lateral wing outlet joint flange gasket ring is carried out to sealing property detection.
Above technical characterictic has formed most preferred embodiment of the present invention, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, meets the needs of different situations.
