Abstract
The invention relates to a quick connector of ground tubes of oil field, wherein it is formed by upper connector, positioning steel ball, spring, connecting sheath, sealing ring, lower connector, strong magnetic plate, locking pin, and unlocking hole; said upper and lower connectors are inserted; the upper end of connecting sheath has spring and positioning steel ball; the upper end of lower connector has sealing ring, to be sheathed into the sealing groove at the upper end of lower connector; the middle of lower connector has locking pin; the strong magnetic plate and unlocking plate are at the lower end of connecting sheath; when the pressure of tube is zero, the locking pin can be adsorbed by the strong magnetic plate; if it is not adsorbed, other matters can lift back the unlocking hole; and the strong magnetic plate is connected to the screw of lower connector. The invention has high sealing property and easy detachment.
Description
Technical field:
The present invention relates to a kind of oilfield field and explore the oil field floor pipeline quick-acting connector of using in the formation testing manufacturing process.
Background technology:
At present, in the oil field prospecting formation testing, generally use union to carry out surface line and connect.Because in use there is following point in union: will pound tightly with sledgehammer when using union, an engineering construction need connect tens of pipelines, need pound tight tens unions, and constructor's labour intensity is very big; The union sealing reliability is low, when bearing high pressure, occurs thorn easily and leaks; Poor stability when using sledgehammer to pound tight union, spark often occurs, and the well that natural gas is arranged is existed potential safety hazard; In-line has under the situation of pressure, hurts sb.'s feelings easily during the dismounting pipeline.
Summary of the invention:
The object of the invention is to provide a kind of oil field floor pipeline quick-acting connector, and it has solved the use oil that exists in the prior art and will pound tightly with sledgehammer during the ninth of the ten Heavenly Stems, and constructor's labour intensity is big; The union sealing reliability is low, is prone to thorn and leaks when bearing high pressure; The problem of casualty accident easily takes place in poor stability.
The technical solution adopted for the present invention to solve the technical problems is: oil field floor pipeline quick-acting connector; Sealing means adopts twice O RunddichtringO to seal, and makes the pipe connector sealing performance reliable; Be provided with the steel ball positioner, can make and in operating process, manually can feel and put in place, can prevent from also to connect that overcoat is loosening takes place, arbitrarily rotate; Be provided with the pressure self-locking device, when in the pipeline pressure being arranged, self-locking device work prevents that pipeline from having under the pressure state, connects overcoat and takes place arbitrarily to rotate, and causes pipeline disengaging accident; Connected mode adopts the spline mode, need not screw thread, and it is convenient to connect the velocity of sound.This pipeline quick connector is made up of top connection, locking ball, spring, connection overcoat, sealing ring, lower contact, strong magnetic piece, stop pin, unlock hole; Top connection and lower contact are for pegging graft, the set upper side is provided with spring and locking ball outside connecting, be provided with 2 groups of sealing rings in the lower contact upper end, sealing ring is enclosed within the seal groove of lower contact upper end, to go up lower contact during connection earlier pegs graft, be that the lower contact sealed end is when entering in the top connection annular seal space fully, top connection annular seal space top locking groove and the embedding mutually of lower contact sealed end top scotch, promoting to connect overcoat makes its spline slide into the summit along the keyway direction of top connection, and be provided with stop pin at lower contact middle part, strong magnetic piece, unlock hole is located at the lower end that connects overcoat, if the pipe internal pressure is unloaded when being zero, stop pin is not sucked back by strong magnetic piece, stop pin is pushed up back by unlock hole with other object, and strong magnetic piece is threaded with lower contact and is threaded.When connecting, at first top connection, lower contact are pegged graft, make sealing ring enter into the sealed end of top connection fully, realize sealing; After sealing ring puts in place, promote to connect overcoat and make its spline slide into the summit along the keyway direction of top connection, overcoat to the locking ball that is rotatably connected to the right arrives anchor point; When in the pipeline pressure being arranged, pressure transfers the pressure to above the stop pin by the pressure transmission hole on the strong magnetic piece, promotes stop pin and moves to connecting the overcoat direction, and be inserted in the connection overcoat lock hole; So no matter how pipeline shakes, connect the overcoat in-line and have under the situation of pressure and can not rotate the accident of freeing, reach safe and reliable purpose, when carrying out the pipeline dismounting, at first the pressure in the pipeline is unstowed, at this moment stop pin returns original position under the strong magnetic piece magneticaction, if the magnetic force of strong magnetic piece can not make stop pin return the origin-location, can use unlock hole stop pin to be back into original position with other rerum natura, then with the hand keyway position of overcoat that be rotatably connected left to top connection, pipeline can be separated, finish the pipeline dismantlement work.
The invention has the beneficial effects as follows that this floor pipeline quick-acting connector is simple in structure, convenient operating maintenance, fast, the good seal of construction connecting line speed reduces labour intensity, construction safety, is difficult for hurting sb.'s feelings, and use cost is low.
