Abstract
The utility model discloses a large-diameter pipe connector composed of a cast-steel connector body. A socket outer joint is arranged on the connector body, and the socket outer joint is internally provided with a thermal insulating layer, an anticorrosion layer and a rubber sealing ring. A socket inner joint is arranged correspondingly to the socket outer joint, and the socket inner joint is provided with a thermal insulating layer and a snap ring. The utility model is adaptable to connection of large-diameter steel plastic pipes in agriculture and industry fields and daily life.
Description
Technical field
The utility model relates to a kind of large-diameter pipe joint.
Background technique
At present.Being of wide application of steel-plastic composite pipe all can be used in worker, agriculture field, daily life, family, public place etc.Bigbore steel-plastic composite pipe mainly is to be used for the inferior foundation engineering in ground, and the pipe joint that is connected of large-diameter steel-plastic composite pipe generally all is to adopt steel flange to connect, and the shortcoming of this connecting means is that volume is big, the cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of large-diameter pipe joint easy to connect at the defective of above-mentioned large-diameter pipe joint connection.
In order to achieve the above object, the utility model is mainly realized by the following technical solutions.The utility model mainly is made up of the cast steel fittings body, and it is external to be provided with joint socket on fittings body, is provided with thermal-protective coating and anticorrosive coat in joint socket is external, also is provided with rubber seal.Connect with also being provided with in the birdsmouth of the external corresponding setting of birdsmouth, in birdsmouth, connect thermal-protective coating and the snap ring established.
In use, fittings body is enclosed within steel and moulds on the head of pipe, connects the mould pincers with special use it is compressed, connect in the described birdsmouth be enclosed within the required steel that connects mould pipe the head on, connect mould pincers with special use it compressed, then with patch in the birdsmouth joint socket external in, again with cast steel fittings body firm welding.
The utility model compared with prior art has the following advantages.(1) easy for installation, under ground piping, can save the shoveling workload.(2) socket joint good airproof performance.(3) cost of production is light.(4) sound construction.
The utility model is applicable to the connection of the large diameter steel-plastic pipe in worker, agriculture field and the daily life.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
