Abstract

The invention relates to a joint assembly of a hydraulic power plier which is applied to well repair of oil fields and used in the process of connection of hydraulic circuits. The joint assembly of the invention mainly consists of a conical pipe type external joint, a movable joint and a bayonet type external joint. The movable joint is L-shaped; an inner cavity at one end thereof is in the shape of a taper hole, internal threads are arranged in the taper holes, the inner cavity at other end thereof is in the shape of cylindrical holes. The screw threads of the conical pipe type external joint are connected with the L-shaped movable joint in a revolving way; the bayonet type external joint is clamped into the other end of the movable joint. The joint assembly of the invention realizes integrated assembly, convenient and flexible assembly and operation, breaks the restriction that a toggle joint is connected at a fixed position in the past and enjoys fine leak tightness, applicability and reliability.

Description

Rotatable bend connector assembly

Technical field:

The present invention relates to a kind of connector assembly of industrial use, particularly the connector assembly that in the hydraulic pipe line connection process, uses with hydraulic power plier of oil field well workover.

Background technique:

At present, the elbow connection of the well workover hydraulic power plier of domestic production, all be that the fixed position connects, fitting operation is inconvenience very, because coupled position can't be adjusted automatically, be easy to cause the damage of hydraulic link sebific duct in addition, make hydraulic fluid leak, cause unnecessary waste, pollute and be easy to cause with sudden hurt accident to production environment.

Summary of the invention:

The objective of the invention is to, a kind of a kind of rotatable bend connector assembly that can connect in the gyratory directions arbitrary position is provided, can in oil field pipeline connection operation, alleviate operating worker labor intensity, reduce the wasting of resources, reduce sudden hurt accident.

Technical solution of the present invention is as follows:

A kind of rotatable bend connector assembly is mainly combined by the socket of Taper Pipe type, union and bayonet type socket.

Union is L-shaped, and the inner chamber of one end is the taper hole shape, has internal thread in the taper hole, and the inner chamber of the other end is a cylindrical hole.Be threaded on the conical pipe of Taper Pipe type socket, an end screw type that has internal thread with L shaped union is connected; The bayonet type socket is entrapped in the other end of union.

Thus, the present invention has realized combined integrated, install, flexible to operation, has broken the restriction that elbow connection fixed position in the past connects, and has good sealing property, applicability and reliability.

Description of drawings:

Fig. 1, be this new invention rotatable bend connector assembly structural representation.

Fig. 2, Taper Pipe type socket structural drawing.

Fig. 3, L shaped movable joint structure figure.

Fig. 4, bayonet type socket structural drawing.

Among the figure: 1, Taper Pipe type socket, 2, union, 3, Sealing shield ring, 4, outer O RunddichtringO, 5, ball, 6, grease nipple, 7, interior O RunddichtringO, 8, the bayonet type socket.

Embodiment:

As Fig. 1-shown in Figure 4, this new invention rotatable bend connector assembly, mainly external 1 by the Taper Pipe type, union 2 and bayonet type socket 8 combine.

Shown in the figure, it is specifically external 1 by the Taper Pipe type, union 2, Sealing shield ring 3, outer O RunddichtringO 4, ball 5, grease nipple 6, interior O RunddichtringO 7, bayonet type socket 8 combine.

Union 2 is L-shaped, and the inner chamber of one end is a taper hole, has internal thread in the taper hole, and the inner chamber of the other end is a cylindrical hole, and the conical internal thread in the tapered thread of Taper Pipe type socket 1 and union 2 taper holes spins; Bayonet type socket 8 snaps onto in the cylindrical bayonet socket of union 2.The part that snaps in of bayonet type socket 8 is processed with three circle grooves: be equipped with an outer O RunddichtringO 4 in the groove of outermost end, the both sides of outer O RunddichtringO 4 respectively are provided with Sealing shield ring 3, realize sealing with union 2 joint hydraulic oil by two Sealing shield rings 3 and outer O RunddichtringO 4; Central groove is the ball groove, wherein be placed with a circle ball 5, circle ball 5 not only plays a part to make the joint rotation to decide direction, and work to stop that bayonet type socket 8 can not break away from, make its location from union 2, the ball groove is connected with a grease nipple 6 that is installed in union 2 outsides, and the notch of grease nipple 6 also is the mount inlet of ball 5; The groove of inner terminal is placed an interior O RunddichtringO 7, realizes the sealing to the connection place butter.The present invention is by the setting of inside and outside two seal rings, realizes the sealing to the joint, and the sealing when fully having guaranteed the rotation of rotation position.

During work, earlier Taper Pipe type external 1 and union 2 are tightened, Sealing shield ring 3, outer O RunddichtringO 4, interior O RunddichtringO 7 are assembled in bayonet type socket 8, again bayonet type socket 8 is snapped in into union 2.At last with ball 5 from directly pack into the ball positioning groove of bayonet type socket 8 of the internal thread bottom outlet that connects grease nipple 5, make bayonet type socket 8 location.After having decided the position, butter is injected from grease nipple 6, butter enters the ball groove again, has guaranteed enough lubricating of ball 5, for the flexible rotation of steel ball provides sound assurance.In an embodiment of the present invention, the other end of bayonet type socket 8 is a taper pipe thread, when bayonet type socket 8 outer end taper pipe threads are fixedlyed connected with extraneous pipeline, union 2 can be by the turning effort of ball 5, rotate freely along bayonet type socket 8 axis, thereby be implemented in connecting of the epicone cast socket 1 of gyratory directions arbitrary position and extraneous pipeline.Bayonet type socket 8 the other ends also can be the interface of other form, also are identical to interconnect function of the present invention.
