Abstract
A bend type steel-plastic adapter is composed by a bend type steel tube; one end of the bend type steel tube is provided with a connecting pipe fitting with plastic end socket; the connecting pipe fitting with plastic end socket is an adapter bonnet body; the connecting pipe fitting with plastic end socket comprises a joint section; the joint section is arranged on an outer circumference connected with one end of the bend type steel tube; the outer circumference of the joint section is provided with a clamping ring; the outer circumference of the bend type steel tube is provided with a stopper ring. The utility model directly adopts the bend type steel tube as steering pipe fitting and the connecting pipe fitting with plastic end socket is arranged on the bend type steel tube, therefore reducing the flexible connector in the prior art, also decreasing the interface amount. In addition, an O-shaped sealing ring is added on the connection part; the adapter outer side of the connecting pipe fitting with plastic end socket is provided with the clamping ring, therefore further improving the leakproofness, reducing the leakage probability, decreasing the construction intensity, as well as saving the materials and project cost.
Description
Technical field
The utility model relates to a kind of connecting element of pipeline, relates in particular to the joint of a kind of connection steel pipe of using in the gas pipeline system and plastics termination connection pipe fitting, and concrete is a kind of bending head type steel-plastic joint.
Background technique
In the prior art, adopt straight formula steel-plastic joint, flexible connection body and steel elbow to realize turning to of pipeline during the gas pipeline wiring, owing to adopt three assembly assembled on site, increase difficulty of construction and cost greatly, owing in three assemblies two interfaces are arranged, increased the danger that combustion gas is revealed greatly simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is: because in the prior art, adopt straight formula steel-plastic joint, flexible connection body and steel elbow to realize turning to of pipeline during the gas pipeline wiring, owing to adopt three assembly assembled on site, increase difficulty of construction and cost greatly, owing in three assemblies two interfaces are arranged, increased the danger that combustion gas is revealed greatly simultaneously.The utility model provides a kind of bending head type steel-plastic joint for the solution that above-mentioned technical problem adopted that solves in the prior art, described this bending head type steel-plastic joint is made of a bending head type steel pipe, wherein, end at described bending head type steel pipe is provided with a plastics termination connection pipe fitting, described plastics termination connection pipe fitting is the reducing body, include a joining section in the connection pipe fitting of described plastics termination, described joining section is arranged on the excircle that is attached thereto an end of described bending head type steel pipe, the excircle of described joining section is provided with clamping ring, the excircle of described bending head type steel pipe is provided with position-arresting ring, in order to the position of clamping ring and joining section correctly to be set, further, adopt the mode of screw-thread fit to connect between described plastics termination connection pipe fitting and the bending head type steel pipe, adopt the mode of screw-thread fit to connect between described clamping ring and the described joining section; Further again, be provided with the body that one section internal diameter equals described bending head type pipe diameter in the connection pipe fitting of described plastics termination, further, between described joining section and bending head type steel pipe, be provided with the O RunddichtringO, concrete, the inner circumference of described joining section is provided with annular groove, described O RunddichtringO is arranged in the described annular groove, simultaneously, also can be provided with annular groove on the excircle of described bending head type steel pipe, described O RunddichtringO is arranged in the described annular groove.
The utility model and prior art contrast, because directly adopt the bending head type steel pipe as turning to pipe fitting, plastics termination connection pipe fitting is arranged on the bending head type steel pipe,, has also reduced number of ports simultaneously so reduced flexible connection body of the prior art, on joint, increase the O RunddichtringO again, in the outside, connection pipe fitting joint, plastics termination clamping ring is installed,, has been reduced the probability that leaks so further improved seal again, reduce construction intensity, saved material and engineering cost.
