Three, summary of the invention: the purpose of this utility model be to propose a kind of simple in structure, fitting operation is convenient and swift, cost is low, and the pressure test tool that the back is detected tubing head lateral wing outlet joint flange gasket ring sealing property is installed at the scene.
The purpose of this utility model is achieved in that tubing head lateral wing pressure test tool, by control lever, pressure testing plug, O-ring seal, handle and pressure testing joint are formed, the pressure testing plug is a solid, be with O-ring seal on its anterior excircle, have the external thread that is connected with tubing head lateral wing outlet inner hole thread on the excircle of middle part, have the screw of level in the rear portion, be plugged with control lever in the described screw.Have external thread at the control lever rear portion, spin on it handle or socket pressure testing joint, lock nut is threaded onto the control lever outermost, and handle is fixedlyed connected with control lever.
The utility model has solved tubing head the problem that posterior area of fixigena outlet joint flange gasket ring sealing property detects has been installed at the scene, has guaranteed the safe handling and the well control safety of well head set-up.
Four, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the tubing head lateral wing pressure test tool synoptic diagram that is connected with handle;
Fig. 2 is the tubing head lateral wing pressure test tool synoptic diagram that is connected with the 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, the pressure testing joint, 11, vent hole, 12, plug, 13, the pressure testing hole.
Five, embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: shown in Fig. 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 pressure testing joint (10) are formed.Pressure testing plug (1) is a solid, is with O-ring seal (2) on its anterior excircle, has the external thread that is connected with tubing head lateral wing outlet inner hole thread on the excircle of middle part, has the screw of level in the rear portion, is plugged with control lever (7) in the described screw.90 degree have pin-and-hole and screw hole at interval on the excircle at pressure testing plug (1) rear portion, are inserted with straight pin (3) and holding screw (4) in the hole respectively.Be processed with chamfering on pressure testing plug (1) the front end face circumference.Control lever (7) is a solid stock, connects the end with pressure testing plug (1) and is processed with and aforementioned pin-and-hole and corresponding circular hole and the threaded hole of screw hole, and straight pin (3) is through in the circular hole, and holding screw (4) end is screwed in the threaded hole.Have external thread at control lever (7) rear portion, the handle that spins on it (8), lock nut (9) are threaded onto control lever (7) outermost, and handle (8) is fixedlyed connected with control lever (7).Described lock nut (9) is a nut.Also be with wiper block (5) on control lever (7), wiper block (5) is the right cylinder of hollow, has the diversion trench (6) of level on its block excircle, is fixed on the control lever (7) by lock-screw.Wiper block (5) excircle removes diversion trench (6) and locates, and remainder contacts with the canalis pterygoideus inner wall sealing.In the pressure testing joint (10) is cavity, the one end does not seal, end sealing in addition, do not have the external thread that is connected with the screw thread flange on the outer wall of blind end, interval 90 degree are processed with two vent holes (11) in the blind end excircle, plug (12) is installed in it, has the horizontal pressure testing hole (13) that connects pressure testing equipment in the Closed End, described pressure testing hole (13) is communicated with pressure testing joint (10) internal cavity.
The flat valve that will be connected with tubing head places fully open position, the screw thread flange place that tubing head lateral wing pressure test tool is connected by the 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), screw put in place after, dismantle lock nut (9), take off handle (8), again pressure testing joint (10) is placed in control lever (7) rear end, and spin with the screw thread flange.Test medium is injected in pressure testing hole (13) from pressure testing joint (10) in the canalis pterygoideus of tubing head lateral wing outlet, the plug (12) that unloads on the 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 sealing property detect.
