Description
Technical field
The utility model is related to petroleum pipeline technical field, more particularly to a kind of anticreep box cupling for petroleum pipeline.
Background technology
Pipeline is that carried of crude oil is most economical, a kind of rational means of transportation.Pipeline crude oil, the company between oil pipe
The mode of connecing is typically with tubing coupling and is attached, and tubing coupling has tubulose box cupling body, and the two ends of box cupling body have
Connection internal thread, during using tubing coupling connected pipes, internal thread is connected tubing coupling is screwed into externally threaded oil pipe
It is interior, oil continuative transport pipeline is formed with this, realize the continuative transport of oil.Above-mentioned tubing coupling of the prior art and oil pipe
Between connection sealing be usually first to wind glass fiber or the rope made of hemp in the external screw thread of oil pipe, afterwards being tied with glass fiber or the rope made of hemp
Oil pipe is screwed into tubing coupling, and the problem that above-mentioned seal form is present is：One is that oil pipe and tubing coupling install relatively cumbersome,
Needs get out glass fiber or the rope made of hemp in advance, and the rope made of hemp or the elastic or thickness of glass fiber winding can also influence sealing effectiveness in addition,
It is whard to control；Two is practice have shown that carrying out oil pipe and tubing coupling sealing, sealing effect in the form of glass fiber or rope made of hemp winding
It is really bad, easily there is crude oil Seepage during use.
Utility model content
In order to overcome the problem of existing technical deficiency, the utility model provides a kind of anti-uncoupling for petroleum pipeline
Hoop.
What the technical solution of the utility model was realized in：A kind of anticreep box cupling for petroleum pipeline, including box cupling
Body and the protective cover ring positioned at box cupling body two ends, the box cupling inner body wall are provided with the internal thread being connected with petroleum pipeline,
Uniform some projections, set on the petroleum pipeline outer wall with protective cover ring correspondence position on the protective cover ring inwall circumferencial direction
There is snap ring, uniform some latches on the snap ring circumferencial direction, the projection realizes clamping with latch corresponding matching.
Preferably, the cross sectional shape of the projection and latch is trapezoidal.
Preferably, the snap ring is connected on the petroleum pipeline by bearing, realizes the rotation of snap ring, convenient adjustment with
The cooperation of protective cover ring.
The utility model beneficial effect is：Carried out with latch on snap ring using the projection on protective cover ring in the utility model
Coordinate, realize the tight connection of box cupling body and petroleum pipeline, wherein, snap ring is connected on petroleum pipeline by bearing, energy
Convenient regulation snap ring realizes the clamping with protective cover ring.
Brief description of the drawings
Fig. 1 is that box cupling body shows with the structure of protective cover ring in a kind of anticreep box cupling for petroleum pipeline of the utility model
It is intended to；
Fig. 2 is the structural representation of the box cupling body of the anticreep box cupling that the utility model is used for petroleum pipeline；
Fig. 3 is the structural representation that the utility model is used for snap ring in the anticreep box cupling of petroleum pipeline；
In figure：1 box cupling body, 2 protective cover rings, 3 projections, 4 snap rings, 5 latches.
Specific embodiment
The utility model is described further in conjunction with the accompanying drawings and embodiments.
As described in Fig. 1-3, a kind of anticreep box cupling for petroleum pipeline, including box cupling body 1 and positioned at box cupling body two
The protective cover ring 2 at end, the inwall of box cupling body 1 is provided with the internal thread being connected with petroleum pipeline, the inwall of protective cover ring 2 circle
Uniform some projections 3, snap ring 4, the snap ring are provided with the petroleum pipeline outer wall with the correspondence position of protective cover ring 2 in circumferential direction
Uniform some latches 5 on 4 circumferencial directions, the projection 3 realizes clamping with the corresponding matching of latch 5.
The petroleum pipeline one end being connected with box cupling is needed to be provided with external screw thread in the utility model, the interior spiral shell with box cupling body 1
Line coordinates realizes connection, in addition, box cupling body 1 is respectively arranged at two ends with a protective cover ring 2, the width 1/3 of the protective cover ring 2
With box cupling body 1 be connected, and the box cupling body 1 external diameter less than the protective cover ring 2 external diameter, the protective cover ring 2
The cross sectional shape of upper process 3 is trapezoidal, and the snap ring 4 is arranged on petroleum pipeline by bearing, rotates snap ring 4 and realizes on snap ring
The cooperation of latch 5 and projection 3, the projection 3 and latch 4 are with being combined into wedge-like engagement.
The cross sectional shape of latch 4 is trapezoidal in the utility model, and each latch 4 is two neighboring prominent with protective cover ring 2
The draw-in groove formed between 3 is played to coordinate.
Coordinated with latch on snap ring using the projection on protective cover ring in the utility model, realize box cupling body and
The tight connection of petroleum pipeline, wherein, snap ring is connected on petroleum pipeline by bearing, conveniently regulation snap ring can be realized and protection
The clamping of cover ring.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
Various modifications and alterations are made without departing from spirit and scope of the present utility model.Therefore, specification is considered as illustrative
And it is nonrestrictive.
