Description
Technical Field
The utility model belongs to the technical field of joints, and relates to a steel-plastic adapter.
Background
In the field of fluid or gas transportation, the commonly used pipes are usually metal pipes such as steel pipes and plastic pipes made of PE (i.e. polyethylene), wherein the metal pipes are usually used for medium-high pressure transportation systems, while the plastic pipes are usually used mainly for low pressure, but since the plastic pipes are not uv-proof, ageing easily occurs when exposed to uv rays, and for safety reasons, the state-related engineering prescribes that the plastic pipes are not allowed to directly enter the room of the user. Therefore, when the high-pressure pipeline is transited to the low-pressure pipeline and the plastic pipeline is led to the home from the garden pipe, a steel-plastic conversion joint is usually required to be adopted for conversion connection.
Steel-plastic crossover connectors typically include a steel pipe section and a PE pipe section that are fixedly connected, such as a steel-plastic crossover tube of reinforced seal construction as disclosed in patent application No. 202122703359.3, wherein the steel pipe section is connected to a metal pipe and the PE pipe section is connected to a plastic pipe. However, the steel pipe sections and the metal pipes are basically connected through threads, welding or grooves, and the concrete connection is inconvenient and slow.

Specifically, when the hydraulic clamp is used, the thin-wall clamping and pressing pipe and the thin-wall pipe fitting are respectively inserted into two ends of the clamping and pressing joint, and then acting force is respectively applied to the two ends of the clamping and pressing joint by utilizing the hydraulic calipers, so that the thin-wall clamping and pressing pipe and the clamping and pressing joint and the thin-wall pipe fitting and the clamping and pressing joint are simultaneously deformed and fixedly connected together (namely clamping and pressing connection). By such an arrangement, the convenience of the changeover connection with the PE pipe section is greatly improved.

Particularly, during welding, the welding flux can be filled into the filling groove and the annular groove, so that the connection between the thin-wall clamping and pressing pipe and the steel pipe section is firmer.
In the steel-plastic adapter, the annular sealing groove is arranged on the step surface of the abutting step, the sealing gasket is embedded in the annular sealing groove, and the right end surface of the thin-wall clamping and pressing pipe abuts against the sealing gasket to form sealing.
The annular sealing groove is arranged on the step surface of the abutting step, the sealing gasket is embedded in the annular sealing groove, and when the right end part of the thin-wall clamping and pressing pipe is inserted into the left end opening of the steel pipe section and abuts against the abutting step, the right end surface of the thin-wall clamping and pressing pipe abuts against the sealing gasket embedded in the annular sealing groove to form sealing, so that the joint of the thin-wall clamping and pressing pipe and the steel pipe section is prevented from leaking.
In the steel-plastic adapter, a plurality of annular anti-drop grooves are formed in the position, close to the left end, of the outer side of the thin-wall clamping and pressing pipe along the axial direction of the thin-wall clamping and pressing pipe.
An annular anti-drop groove is formed in the outer side of the thin-wall clamping and pressing pipe, which is close to the outer side of the left end part, along the axial direction of the thin-wall clamping and pressing pipe, and an annular anti-drop part extruded into the annular anti-drop groove can be automatically formed on the clamping and pressing pipe when the thin-wall clamping and pressing pipe is in clamping and pressing connection with the clamping and pressing joint, so that the tensile pulling capacity between the thin-wall clamping and pressing pipe and the clamping and pressing joint is improved.
In the steel-plastic adapter, the left groove wall of the annular anti-drop groove is perpendicular to the outer peripheral wall of the thin-wall clamping and pressing pipe, and the right groove wall of the annular anti-drop groove is obliquely arranged towards the right. Through above-mentioned setting for tensile effect of pulling out is better.
