Abstract
The utility model relates to an oil field well apparatus, and particularly relates to an anti-spraying box fast connection device. The anti-spraying box fast connection device comprises an anti-spraying box joint, a locking cylinder, a return spring, an anti-spraying pipe joint, a position-specified steel ball, an anti-spraying pipe, and a sealing ring. the locking cylinder is jointed outside the anti-spraying pipe joint, the return spring is arranged at the connection part of the locking cylinder and the anti-spraying pipe joint to realize the relative sliding of the locking cylinder and the anti-spraying pipe joint, the locking cylinder and the anti-spraying pipe joint are sealed through the sealing ring, one end of the anti-spraying pipe joint is connected to the anti-spraying box joint, and the other end of the anti-spraying pipe joint is connected to the anti-spraying pipe, and the position-specified steel ball is arranged at the connection part of the anti-spraying pipe joint and the anti-spraying box joint. The device is advantageous in that the device has the properties of convenient operation, safety, laborsaving, simplicity, and high efficiency; operators can complete the connection and detachment of the anti-spraying box by controlling the hydraulic mechanism, thus, the check of swabbing tools can be completed on ground to prevent the operators from frequently detaching of the anti-spraying pipe while checking the swabbing tools, thereby reducing the risks during the operation.
Description
Technical field
The utility model relates to a kind of oil field well and uses equipment, particularly a kind of blowout prevention box Quick Connect Kit.
Background technology
In the oil exploitation,, possibly bring out blowout during swabbing operation, so swabbing operation has the well control requirement equally owing to there is the uncertainty of strata pressure.Promptly after pumping blowout or well kick generation, can be effectively controlled.Therefore, in swabbing operation, generally all will install lubricator additional, the blowout prevention box is installed on lubricator top, the bottom of lubricator is connected on the production tree.When blowout, well kick taking place or have other to need, swab and weighted lever are mentioned in the lubricator, then closing well.In use can there be certain wearing and tearing in the seal of pumping instrument, in order not influence the pumping quality, must in time check the pumping instrument on request.When inspection, operating personnel need frequently climb to and connect on the production tree and the dismounting lubricator, inspection pumping instrument.These actions all are that operating personnel stand on the production tree and accomplish, and the production tree top is overhead higher, and smooth surface, and the tumble injury of slipping easily above operating personnel step down in has increased the risk of swabbing operation.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of blowout prevention box Quick Connect Kit is provided, and simple operation has characteristics such as safe, laborsaving, easy, efficient.
Its technical scheme is: mainly be made up of blowout prevention box joint, locking tube, return spring, lubricator joint, spacing steel ball, lubricator, sealing ring; The locking jacket casing is connected on the outside of lubricator joint; The locking tube is provided with back-moving spring with the junction of lubricator joint; Realize both relative slips, through sealing ring sealing locking tube and lubricator joint, lubricator joint one end connects blowout prevention box joint; The other end connects lubricator, and the junction of lubricator joint and blowout prevention box joint is provided with spacing steel ball.
The beneficial effect of the utility model is: this device simple operation; Have safe, laborsaving, easy, efficient; The connection that operating personnel just can accomplish the blowout prevention box through the control hydraulic mechanism with separate; Just can accomplish the inspection of pumping instrument on the ground, thereby avoid operating personnel, reduce the risk in the operation because of frequent dismounting lubricator inspection pumping instrument.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: blowout prevention box joint 1, locking tube 2, return spring 3, lubricator joint 4, spacing steel ball 5, hydraulic cavities 6, lubricator 7, sealing ring 8.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of blowout prevention box joint 1, locking tube 2, return spring 3, lubricator joint 4, spacing steel ball 5, hydraulic cavities 6, lubricator 7, sealing ring 8; Locking tube 2 is socketed in the outside of lubricator joint 4; Locking tube 2 is provided with back-moving spring 3 with the junction of lubricator joint 4, realizes both relative slips, and both spaces form hydraulic cavities 6; Through sealing ring 8 sealing locking tubes 2 and lubricator joint 4; Lubricator joint 4 one ends connect blowout prevention box joint 1, and the other end connects lubricator 7, and lubricator joint 4 is provided with spacing steel ball 5 with the junction of blowout prevention box joint 1.
During use, blowout prevention box joint is installed on the blowout prevention box, and the lubricator joint is connected with lubricator, realizes being connected and separating of blowout prevention box joint and lubricator joint through moving of locking tube.When inspection pumping instrument, operating personnel need not frequently to climb to and connect on the production tree and the dismounting lubricator.Only need to rely on the gravity of blowout prevention box just can realize connecting, and when swabbing operation, can not extract.When needs are dismantled, open locking device through hydraulic control, watch out for the spray box on only needing gently just can realize dismantling.Can effectively avoid operating personnel to cause the risk of tumble injury because of frequent dismounting blowout prevention box.After the controlling organization action, the locking tube slides smooth and easy, does not have catching phenomenon, can lock smoothly and release.The seal of blowout prevention box Quick Connect Kit, under the situation of bearing the pumping fluid pressure, sealing is reliable, does not come off and the seepage phenomenon.Good seal between blowout prevention box jointing and the lubricator jointing, the leakproof phenomenon, connect move when separating smooth and easy, no catching phenomenon.
