Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a pipeline connector. The utility model solves the technical problem of how to firmly connect the RTP pipe and the metal pipe.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a pipeline connector, includes the connecting pipe, the connecting pipe is one section RTP pipe, and two tip of connecting pipe all are provided with seals the ring, seal the ring have be used for with connecting pipe lateral wall hot melt be connected connecting portion and be used for with connecting pipe tip hot melt be connected sealing, one of them sealing the connecting portion of ring and outwards extend along circumference and be formed with to support to lean on the portion, support to have the flange by one side of portion, its opposite side butt has the ring flange, through a plurality of bolt fixed connection between flange and the ring flange.
This pipe connection ware of pipe connection ware can realize being connected with the RTP pipe (it needs to be noted that, the tip of the RTP pipe that is connected with this pipe connection ware needs to be provided with equally and seals the ring, the hot melt through two rings that seal is connected realizes being connected of this pipe connection ware and RTP pipe), one side butt of the portion of supporting of this pipe connection ware has connect the flange, its opposite side butt has the ring flange, through a plurality of bolt fixed connection between flange and the ring flange, the flange can realize being connected with the tubular metal resonator, thereby realize this pipe connection ware respectively with the RTP pipe with the tubular metal resonator be connected, and, the RTP pipe adopts hot melt to be connected with this pipe connection ware, the tubular metal resonator adopts flange joint with this pipe connection ware, make RTP pipe and the tubular metal resonator that is connected with this pipe connection ware firm in connection.
Meanwhile, the sealing ring can seal the end part of the connecting pipe, so that the middle layer of the connecting pipe cannot be corroded by fluid in the pipe, the fluid in the pipe cannot be polluted by the middle layer, the connecting part of the sealing ring is in hot-melt connection with the outer side wall of the connecting pipe, and the sealing part is in hot-melt connection with the end part of the connecting pipe, so that the effective drift diameter and the flow of the connecting pipe cannot be reduced after the sealing ring is connected with the connecting pipe.
In the above-described pipe connector, the length of the abutting portion in the axial direction is greater than the length of the sealing portion in the axial direction, and the sum of the lengths of the abutting portion and the flange in the axial direction is equal to or less than the length of the connecting portion in the axial direction.
Above-mentioned structure can strengthen the anti deformability who leans on the portion for the flange is more reliable with being connected of ring flange, thereby makes the connection between this pipe connector and the tubular metal resonator more firm.
In the above-described one of the pipe connectors, an end surface of the abutting portion is flush with an end surface of the seal portion.
The terminal surface that leans on the portion and the terminal surface looks parallel and level of sealing portion can improve flange and sealing portion, the area of contact who leans on the portion for the flange is more reliable with being connected of ring flange, thereby makes the connection between this pipe connection ware and the tubular metal resonator more firm.
In the above pipe connector, the connecting portion is provided with a chamfer. The chamfer angle can facilitate the sleeving of the flange plates.
Compared with the prior art, the pipeline connector has the advantages that: the RTP pipe and the pipeline connector are connected by hot melting, and the metal pipe and the pipeline connector are connected by flanges, so that the RTP pipe and the metal pipe which are connected by the pipeline connector are firmly connected.
Fig. 1 is a schematic structural view of the present pipe connector.
Fig. 2 is a partially enlarged view of a portion a in fig. 1.
In the figure, 1, connecting pipe; 2. a flange; 3. a sealing ring; 311. a connecting portion; 312. a sealing part; 4. an abutting portion; 5. a flange plate; 6. a bolt; 7. and (6) chamfering.
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
A pipeline connector, refer to fig. 1-2, includes a connecting pipe 1, the connecting pipe is a section of RTP pipe, the RTP pipe of this embodiment is preferably CFRTP pipe, the middle layer is enhancement layer, and is made of continuous glass fiber material with angle staggering, melting winding, plastic impregnation, two ends of the connecting pipe 1 are both provided with sealing ring 3, the sealing ring 3 has a connecting portion 311 for hot-melt connection with the outer side wall of the connecting pipe 1 and a sealing portion 312 for hot-melt connection with the end of the connecting pipe 1, further, a chamfer 7 is provided on the connecting portion 311, the connecting portion 311 of one sealing ring 3 extends outwards along the circumferential direction to form a leaning portion 4, one side of the leaning portion 4 is butted with a flange 2, the other side is butted with a flange 5, the flange 2 and the flange 5 are fixedly connected through a plurality of bolts 6, further, the length of the leaning portion 4 along the axial direction is greater than the length of the sealing portion 312 along the axial direction, the length of the abutting part 4 and the length of the flange 5 in the axial direction are less than or equal to the length of the connecting part 311 in the axial direction, and the end surface of the abutting part 4 is flush with the end surface of the sealing part 312.
