Abstract
The utility model relates to a hot melt plugging connecting pipe with a metal screw joint, which comprises an antiskid bar (1) provided at the outer side of the metal screw joint and contacted with thermal plastic material, two waterproof annular slots (2) at two sides of the antiskid bar (1), and a seal port (3) at the inner side of the bottom of the metal screw joint, wherein the antiskid bar is in an inverted cone (11) form along radial direction, the seal port (3) is provided with an upper waterproof annular slot (4). The utility model has the advantage that the hot melt plugging connecting pipe can reduce the weigh of the metal screw joint and improve the joint force between the thermal plastic material of a connecting pipe and the metal screw joint, to confirm the connection quality and safety between the connecting pipe and connected pipes.
Description
Technical field
The utility model relates to a kind of thermofusible spigot connection pipe fitting with metal threaded joint, relates in particular to the structure of the metal threaded joint of this connection pipe fitting.
Background technique
Thermofusible spigot connection pipe fitting with metal threaded joint is formed by injection molding by metal threaded joint and thermoplastic material, generally is used for the connection of the following pipeline of external diameter 160mm.
Its principle is inserted fusing tubing end the bellmouth of connection pipe fitting and is fixed for holding outside heating and melting simultaneously with the thermoplastic pipe with thermoplastic material end bell in the thermofusible spigot connection pipe fitting of metal threaded joint is inboard, cools off fully until the joint; The metal threaded joint of connection pipe fitting is connected with the inipple of same size, fastening with machinery type.
By Fig. 1, Fig. 2 as seen: must be more firm in the prior art for the metal threaded joint and the thermoplastic material combination that make connection pipe fitting, Security is higher, and metal parts is generally adopted following structure setting:
With contacted metal threaded joint arranged outside tread plate 1 of thermoplastic material and water stop ring groove 2, make thermoplastic material fill up the water stop ring groove, the tread plate and the water stop ring groove that guarantee thermoplastic material and metal threaded joint have stronger combination force, can also play the sealing effect when the thermoplastic cooling is shunk;
In metal threaded joint bottom inside envelope material mouth 3 is set, enters threaded area when preventing the thermoplastic material mold filling, make thermoplastic material and metal threaded joint inboard that stronger combination force be arranged.
But because the difference of Shooting Technique, connection pipe fitting connection technology and related personnel's operation is difficult to press code requirement and implements in real work.For improving the quality and the Security of connection pipe fitting and connection back pipeline, be necessary the structure of metal threaded joint is improved design.
Summary of the invention
The utility model technical issues that need to address have provided a kind of thermofusible spigot connection pipe fitting with metal threaded joint, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: with the tread plate in the contacted metal threaded joint of the thermoplastic material outside and at the water stop ring groove of tread plate two sides, at the envelope material mouth of metal threaded joint bottom inside; Described tread plate is being reverse tapered shapes in the radial direction; On described envelope material mouth, also settle water stop ring groove on.
Compared with prior art, the beneficial effects of the utility model are: promptly reduced the weight of metal threaded joint, improved the combination force of connection pipe fitting thermoplastic material and metal threaded joint again, guaranteed the quality and the safety of connection pipe fitting and connection back pipeline.
Description of drawings
Fig. 1 is with the thermofusible spigot connection pipe fitting schematic representation of metal threaded joint in the prior art;
Fig. 2 is the sectional drawing of metal threaded joint among Fig. 1;
Fig. 3 is the utility model structural representation;
Fig. 4 is the sectional drawing of metal threaded joint among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 3, Fig. 4 as seen: the utility model comprises: with the tread plate 1 in the contacted metal threaded joint of the thermoplastic material outside and at the water stop ring groove 2 of tread plate 1 two sides, at the envelope material mouth 3 of metal threaded joint bottom inside; Described tread plate 1 is being inverted cone 11 shapes in the radial direction; On described envelope material mouth 3, also settle water stop ring groove 4 on;
The degree of depth of described inverted cone 11 greater than the profile of tooth of tread plate 1 at the bottom of the footpath and the height of water stop ring groove 2;
Described upward water stop ring groove 4 is the wide 1.5～10mm of being, is the groove of 1～6mm deeply.
Reverse tapered shapes is in order to increase the area that is connected in thermoplastic material and the metal threaded joint outside in the utility model, make both that enough combination forces be arranged, can effectively prevent when connection pipe fitting is connected with other joints because of the loosening of uneven metal threaded joint that causes and thermoplastic material of exerting oneself, guarantee to connect the quality and the safety of back pipeline, play the sealing seal action simultaneously.
Go up the water stop ring groove in the utility model and be in order to increase the area that is connected of thermoplastic material and metal threaded joint inboard, make both that enough combination forces be arranged, can effectively prevent when connection pipe fitting is connected with other joint mechanical because of the loosening of uneven metal threaded joint that causes and thermoplastic material of exerting oneself, strengthen the sealing of thermoplastic material and envelope material mouthful linkage interface simultaneously, guarantee the quality and the Security of connection pipe fitting and connection back pipeline.
