Abstract

The utility model discloses an organic glass return bend connecting piece, including connecting ring canal and sealing washer. The inner wall of the connecting ring pipe is provided with an annular groove, and one side of the connecting ring pipe is provided with an annular plug. When the organic glass bent pipe connecting piece is used for connection, the sealing ring is arranged in the annular groove in the inner wall of the connecting ring pipe, and then the elbow to be connected is inserted from one side of the connecting ring pipe with the plug connector and the straight pipe is inserted from the other side of the connecting ring pipe with the plug connector, so that the pipeline connection can be completed. The inner diameters of the elbow, the straight pipe and the connecting ring pipe plug are the same, so that the change of the flowing state of the medium at the joint of the pipeline can be avoided. The utility model discloses a this return bend connecting piece has solved organic glass return bend junction internal diameter sudden change, ageing resistance can be poor, life weak point scheduling problem. This utility model is used for organic glass pipe connection field.

Description

Organic glass bent pipe connecting piece
Technical Field
The utility model relates to a connecting device, concretely relates to organic glass return bend connecting device.
Background
Because the oil gas pipeline lays along the topography and has the fluctuation of different degrees, often adopt organic glass fluctuation pipe to study intraductal flow state in the laboratory. The organic glass elbow can be manufactured by a special mould and can also be manufactured by hot bending. The flow state of the fluid in the fluctuation pipe can be visually displayed after the manufactured organic glass elbow is connected with the organic glass straight pipe.
Common organic glass pipeline connection mode can be adopted when organic glass elbow is connected with the straight tube, for example: adhesive connections, flange connections, threaded connections, etc. However, the adhesive connection and the flange connection have the defects of poor aging resistance, change of the inner diameter of the connection part and the like in the actual use process; the threaded connection has the problems of complex processing of internal and external threads, easy stress concentration, difficult control of elbows, straight pipes on the same vertical plane and the like. Patent CN 203297831U reports a flexible connector of organic glass tube, which can be adjusted at any angle, but the inside diameter of the connection part is also changed suddenly.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing problem, the utility model provides a can realize that the junction internal diameter is unchangeable, connect simple, dismantle convenient, sealing performance is good, the even connecting piece that is used for connecting organic glass elbow and straight tube of atress.
The utility model discloses a following technical scheme realizes:
an organic glass bent pipe connecting piece comprises a connecting ring pipe and a sealing ring, wherein an annular groove is formed in the inner wall of the connecting ring pipe.
Further conduct the utility model discloses technical scheme's improvement, go up the ring tube structure asymmetry, wherein one side has the annular bayonet joint.
The utility model discloses an effective effect: when the organic glass bent pipe connecting piece is used for connection, the sealing ring is arranged in the annular groove in the inner wall of the connecting ring pipe, then the elbow to be connected is inserted from one side of the connecting ring pipe with the annular plug connector, and the straight pipe to be connected is inserted from the other side, so that bent pipe connection can be completed. The elbow and the pipeline are pulled out outwards to finish the disassembly. The inner diameters of the elbow, the straight pipe and the annular plug-in connector which need to be connected are all consistent, the equal diameter and the uniform stress of the joint of the elbow can be realized, and the change of the medium flowing state at the joint of the pipeline is avoided.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a cross-sectional view of the overall structure of the embodiment of the present invention after the connection.
Detailed Description
The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiment of the present invention.
As shown in fig. 1, the utility model relates to an organic glass return bend connecting piece, including connecting ring canal 1 and sealing washer 2, connecting ring canal 1 inner wall has annular groove for packing into sealing washer 2. One side of the connecting ring pipe 1 is provided with an annular plug connector.
As the preferred embodiment of the present invention, the annular groove connecting the inner wall of the ring pipe 1 is designed to be three, and the outer surface of the plug is frosted.
When the organic glass bent pipe connecting piece is used for realizing pipe connection, the sealing rings 2 are arranged in three annular grooves in the inner wall of the connecting ring pipe 1, then an elbow to be connected is inserted from one side of the connecting ring pipe 1 with the plug-in connector, and the straight pipe is inserted from the other side to the step position, so that the pipe connection can be completed.
After the organic glass bent pipe connecting piece is connected, the inner diameters of the connecting joints of the elbow, the straight pipe and the connecting ring pipe 1 are consistent, the equal diameter and uniform stress of the pipeline joint can be realized, and the change of the medium flowing state of the pipeline joint is avoided. This organic glass return bend connecting piece's installation convenient to use, when needs are dismantled, only need fixed connection ring canal 1, successively follow both sides with straight tube and elbow extract can.
The foregoing has described the principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, but rather is described in the foregoing embodiments and the description only to illustrate the principles of the invention and that various modifications and substitutions can be made without departing from the spirit and scope of the invention, and these modifications and substitutions are intended to be included within the scope of the invention as defined in the claims.
