Description

Pipeline connector
Technical Field
The utility model belongs to the technical field of pipeline connection, and relates to a pipeline connector.
Background
In water supply, water drainage, heat supply, gas supply, long-distance petroleum and natural gas transportation, agricultural irrigation, hydraulic engineering and various industrial devices, the transportation needs to be carried out by means of pipelines, the long-distance transportation needs to relate to the connection between the pipelines, and may relate to the connection between plastic pipes, between metal pipes, between RTP pipes and metal pipes and between pipes of the same material or different materials, wherein, the RTP pipe is a fluid transportation pipe which is compounded into a whole by corrosion-resistant plastics and non-corrosion-resistant high-strength materials, most of the existing RTP pipes adopt a three-layer structure, the inner layer is a corrosion-resistant and wear-resistant thermoplastic layer, the middle layer is a reinforcing layer with the reinforcing function, the outer layer is an outer coating plastic layer with the protective function, the application field is wide, the hot melting connection can be adopted between the plastic pipes at present, and the welding connection can be adopted between the metal pipes, but there is currently no good way of joining RTP tubes to metal tubes.
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.
