Abstract
The invention discloses a free rotation type pipe joint. The free rotation type pipe joint comprises a plurality of joint units of the same structure. Each joint unit comprises a connection part and a joint part communicating with the joint part, one side of the connection part is provided with a first clamping-connection protrusion and a first clamping-connection groove, the other side of the connection part is provided with a second clamping-connection protrusion and a second clamping-connection groove, the size of the first clamping-connection protrusion corresponds to that of the second clamping-connection groove, the size of the second clamping-connection protrusion corresponds to that of the first clamping-connection groove, and two sealing ring installation grooves are formed in the ends of the two sides of the joint unit. The multiple joint units are sequentially connected in the mode that the first clamping-connection protrusions, the second clamping-connection grooves, the second clamping-connection protrusions and the first clamping-connection grooves are clamped, connected and matched, sealing rings are arranged at the connection positions, and pipeline joint bodies are connected to the connection parts of the two joint units on the outermost sides in a clamping-connection mode. The free rotation type pipe joint can meet the requirements that a plurality of reversing pipelines are simultaneously installed on a pipe coupling and meanwhile can be subjected to angle-free reversing.
Description
Technical field
The present invention relates to petroleum pipeline field, and in particular to a kind of free rotation pipe joint.
Background technology
Petroleum pipe coupling is the requisite element of connection petroleum transportation pipeline, and all kinds of pipe box cuplings carry different functions
Need.For example, elbow box cupling just has the effect that petroleum pipeline right angle commutates, and has a wide range of applications example.But it is traditional
Swan neck box cupling be all can only to accomplish 90 ° of commutations, and can not meet on a pipe box cupling while installing multiple reversing pipelines
Require.
The content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of free rotation pipe joint, and the pipe box cupling can meet one
Simultaneously the requirement of multiple reversing pipelines is installed on individual pipe box cupling, while arbitrarily angled commutation can be accomplished.
The purpose of the present invention is by the following technical programs implementing：
A kind of free rotation pipe joint, including multiple structure identical connector units, the connector unit include connecting portion and
The connector portions communicated with connecting portion, connector unit is integrally in T shape, the side of the connecting portion be provided with the first clamping it is raised and
First clamping groove, the opposite side of connecting portion is provided with the second clamping projection and the second clamping groove, and first clamping is raised
Corresponding to the size of the second clamping groove, second clamping is raised corresponding to the size of the first clamping groove, connector unit
Two sealing ring mounting grooves are offered on the termination of both sides, multiple connector units are sequentially by the first clamping projection and the second clamping groove
And second clamping projection be connected with the snap-fit of the first clamping groove, junction is provided with sealing ring, the sealing ring
In sealing ring mounting groove, the clamping on the connecting portion of outermost two connector unit is connected with pipe joint.
Further, the connector unit includes three.
Further, it is coated with corrosion-resistant finishes on the inwall of the connecting portion and connector portions.
The present invention provides a kind of free rotation pipe joint, and the pipe box cupling includes multiple structure identical connector units, many
Individual connector unit is sequentially by the first clamping projection and the second clamping groove and the raised card with the first clamping groove of the second clamping
Fit system connection is connect, and junction sealing ring is provided with, ensureing sealing simultaneously as using the connected mode of clamping,
Each connector unit can circumferentially rotate arbitrarily angled, you can with arbitrarily angled commutation, and can meet pacify simultaneously on a pipe box cupling
Fill the requirement of multiple reversing pipelines.

Specific embodiment
As Figure 1-Figure 2, a kind of free rotation pipe joint described in the embodiment of the present invention, including three structures is identical
Connector unit, connector unit includes connecting portion 1 and the connector portions 2 that communicate with connecting portion 1, and connector unit is integrally in T shape, even
The side of socket part 1 is provided with the first clamping raised 3 and the first clamping groove 4, and it is convex that the opposite side of connecting portion 1 is provided with the second clamping
Play 5 and the second clamping groove 6, raised 3, the second clamping projection 5 and first corresponding to the size of the second clamping groove 6 of the first clamping
The size of clamping groove 4 is corresponding, offers two sealing ring mounting grooves 7 on the both sides termination of connector unit, three connector units according to
Sequence is by the first clamping raised 3 and the clamping engagement side of the second clamping groove 6 and the second clamping raised 5 and the first clamping groove 4
Formula connects, and junction is that joint is provided with sealing ring 8, and sealing ring 8 is located in sealing ring mounting groove 7, connects outermost two
Upper clamping on the connecting portion 1 of head unit is connected with pipe joint 9.
Corrosion-resistant finishes is coated with the inwall of connecting portion 1 and connector portions 2, the service life of joint is improved.
The present invention is ensureing sealing simultaneously as using the connected mode of clamping, each connector unit can be circumferentially rotated
It is arbitrarily angled, you can with arbitrarily angled commutation, can meet on a pipe box cupling while installing the requirement of multiple reversing pipelines, it is easy to
Promote the use of.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to,
For a person skilled in the art, it still can be adjusted to the technical scheme described in foregoing embodiments, or
Person carries out equivalent to which part technical characteristic, all any modifications within the spirit and principles in the present invention, made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
