Abstract
The utility model discloses a plastic flange, comprising a connecting pipe and a connecting plate. An outer wall of the connecting pipe and the connection of the connecting plate are provided with a strengthen ring. An inner wall of the connecting pipe is provided with a ferrol, and the connecting plate is provided with a screw hole. When the utility model is connected with the composite pipe, the plastic lining of the composite pipe is only needed to connect with the connector of the flange by hot melting, thereby making sure the good sealing of the pipeline and overcoming problem of dropping and leaking of other connection styles, therefore, the utility model has the advantages of good sealing, simple assembly, using plastic in the body material and lower cost.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly relates to a kind of plastics flange.
Background technique
Traditional flange is metal material, generally between it and the pipeline adopts screwed connection, and have safe and reliable advantage, but have the manufacture cost height, the shortcoming that install, dismounting is complicated, and be not suitable for being connected with the composite metal-plastic pipe material.
What existing composite pipe adopted mostly is screw thread " FERRULETYPE " link, by precession nut compresses seal and lock jump ring and reach the mechanical connection manner that not only seals but also connect, has the simple advantage such as quick of construction, but also have following shortcoming: the jump ring coupling mechanism force can't be born the pressure requirement of φ 63 above specification pipe-line systems, is not suitable for big specification pipe-line system; Poor sealing is easily leaked when pipeline is subjected to radial load; The bonding strength of hot melt adhesive decays behind the composite pipe hot melt adhesive chance water, and composite pipe meeting layering causes in the inner plastic and contracts.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, the plastics flange that provide that a kind of cost is low, good airproof performance, simple installation and being fit to is connected with the composite metal-plastic pipe material.
For reaching above-mentioned purpose, the utility model adopts following solution: a kind of plastics flange, comprise land, and it is characterized in that: it also comprises the connecting tube that is connected as a single entity with land, the joint with land on the outer wall of connecting tube is provided with stiffening ring.
Above-mentioned plastics flange is characterized in that: the inwall of described connecting tube is provided with lining ring.
Above-mentioned plastics flange is characterized in that: have screw on the described land.
Compared with prior art, the utlity model has following advantage:
1, the utility model is fit to be connected with composite pipe, when it is connected with composite pipe, only need inner plastic with composite pipe be connected and get final product, guaranteed that pipeline has good sealing property with the connecting tube hot melt of this flange, overcome other Placements droplet, the leakage phenomenon.Therefore, the utlity model has good airproof performance, easy-to-install advantage.
2, the utility model is provided with the rigidity that the purpose of stiffening ring is an enhancing tubing connecting end portion on connecting tube, guarantees that the end of composite pipe is difficult for undergauge, increases tensile strength.
3, the purpose of lining ring is set on the inwall of connecting tube is that the connecting tube plastics subside when preventing hot melt to the utility model.
4, the utility model the purpose that has screw on the land be convenient between this flange and this flange and other pipe fitting between be connected with bolt.
5, material of main part of the present utility model is plastics, and stiffening ring and lining ring are metallic material, so its cost is lower.
