Abstract

The utility model discloses a heat insulation welding joint for steel-plastic composite pipes. The heat insulation welding joint for steel-plastic composite pipes is mainly composed of a socket outer joint and a socket inner joint which is connected with the socket outer joint and is arranged in the socket outer joint. A heat insulation layer and an anticorrosive coating are arranged in the socket outer joint, and a rubber gasket sealing member is also arranged in the socket outer joint. A heat insulation layer is also arranged in the socket inner joint, and a clamping ring is arranged outside the socket inner joint. The utility model is suitable for the connection of steel-plastic composite pipes.

Description

The heat insulation welded joint of steel-plastic composite pipe
The utility model relates to the heat insulation welded joint of a kind of steel-plastic composite pipe.
Being of wide application of steel-plastic composite pipe, the connection of steel-plastic composite pipe all are to adopt steel flange to connect, and the shortcoming of this connecting means is: volume is big, outward appearance is not beautiful, the cost height, stolen easily with the pipe that steel flange connects, as long as, just can steal liquid in pipe as opening steel flange.
The purpose of this utility model is at above-mentioned shortcoming, provides a kind of exterior design attractive in appearance, the heat insulation welded joint of steel-plastic composite pipe easy to connect.
The utility model is to achieve the above object by the following technical solutions.Mainly form by the fittings body that is connected with steel-plastic composite pipe, fittings body is external and with its corresponding setting by joint socket, be located in the external interior joint socket of joint socket and connect composition, be equipped with thermal-protective coating and anticorrosive coat in connecing in the external and joint socket of joint socket, also be provided with rubber seal in joint socket is external.The outside that connects in the joint socket is provided with snap ring.
The utility model compared with prior art has the following advantages and good effect.1. easy for installation, when particularly making underground pipe network, significantly reduce the shoveling workload.2. the socket joint good airproof performance bears the pressure height, generally can be more than the withstand voltage 2.5MPa.3. cost of production is light, is equivalent to 60% of steel flange connection.4; The sound construction insurance during as the petroleum-type conveyance conduit, can avoid suffering pilferage to wait loss.5. the utility model is more attractive in appearance than the steel flange connection, is applicable to the connection of steel-plastic composite pipe.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model overall structure and partial cutaway diagrammatic sketch.
Fig. 2 is the utility model exploded view.
As shown in Figure 1, steel-plastics composite pipe 1 links to each other with fittings body 2, joint this 2 by bell and spigot external 3 and with Its corresponding setting, and be placed in and connect 7 in the bell and spigot in the bell and spigot external 3 and form bell and spigot external 3 In be provided with thermal insulation layer 5, anticorrosive coat 6, also be provided with rubber ring seal part 4, connect in 7 in the bell and spigot and also be provided with Thermal insulation layer 9 connects 7 outer rings and also is provided with snap ring 8 in the bell and spigot.
As shown in Figure 2, steel-plastics composite pipe 1 links to each other with bell and spigot external 3, connects 7 outer ring in the bell and spigot and is provided with Snap ring 8. Connect 7 also connecting steel plastic composites in the socket joint product.
[embodiment]
Fittings body 2 is the cast steel joint, at first is welded in the steel-plastic composite pipe end of corresponding specification, after lining is moulded, adopts the socket joint mode that two steel-plastic composite pipes are docked, and connects the mould pincers with special use, and they are compressed, and then the cast steel joint housing is welded.
The utility model is applicable to the connection of steel-plastic composite pipe.
