Abstract
The utility model discloses a socket steel pipe socket structure, which comprises a pipe socket and a pipe bell mouth, wherein two sealing grooves are arranged at intervals on the axial peripheral wall of the pipe socket, O-shaped sealing rings are respectively arranged in the two sealing grooves, and an exhaust hole and a pressing hole are respectively arranged on the peripheral wall of the pipe bell mouth between the two sealing grooves; the wall thickness of pipe socket is 10mm, seal groove bending part radius be 14mm, the interval between the pipe socket inner wall of seal groove top surface and seal groove department is 20mm, the interval between the twice seal groove central line is 50 mm. Adopt the utility model discloses behind the structure, can succeed the indent and can stabilize the installation sealing washer, satisfy the socket joint steel pipe and suppressed the requirement, can satisfy pipeline 2.5 MPa's pressure requirement.
Description
Technical Field
The utility model relates to a socket steel pipe socket structure.
Background
At present, concrete sizes of socket steel pipe grooves are not given in the technical specification of socket flexible interface steel pipes for water supply and drainage engineering, design sizes of all manufacturers are different and are not transmitted outside densely, and when the socket steel pipes are pressed, pressing failure can be caused due to size design problems.
Disclosure of Invention
An object of the utility model is to provide a socket steel pipe socket structure can successfully indent and can stabilize the installation sealing washer, satisfies the socket steel pipe and suppresses the requirement.
The utility model aims at realizing the structure, which comprises a pipe socket and a pipe bell, wherein two sealing grooves are arranged at intervals on the axial peripheral wall of the pipe socket, O-shaped sealing rings are respectively arranged in the two sealing grooves, and an exhaust hole and a pressurizing hole are respectively arranged on the peripheral wall of the pipe bell between the two sealing grooves; the wall thickness of pipe socket is 10mm, seal groove bending part radius be 14mm, the interval between the pipe socket inner wall of seal groove top surface and seal groove department is 20mm, the interval between the twice seal groove central line is 50 mm.
Adopt the utility model discloses the effect of fixed seal circle then can be solved with "O" type circle to the structure, and the tank bottom is wrapped up in tightly to the sealing washer, can not overturn by the pushover in the installation, can satisfy operation requirement. The key technology of socket joint steel pipe manufacturing of design during socket joint steel pipe indent method and size adopts the utility model discloses behind the structure, can successfully indent and can stabilize the installation sealing washer, satisfied socket joint steel pipe and suppressed the requirement, can satisfy pipeline 2.5 MPa's pressure requirement. The manufacturing method is suitable for manufacturing the socket steel pipe, and has the advantages that the installation is convenient, the installation speed is high, the socket steel pipe is more and more applied to a water delivery pipeline, and the application prospect is good.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the front view cross-sectional structure of the present invention.
Fig. 2 is a dimension diagram of the sealing groove of the present invention.
Detailed Description
A spigot and socket steel pipe spigot structure comprises a pipe spigot 6 and a pipe socket 1, wherein two sealing grooves are arranged on the axial peripheral wall of the pipe spigot 6 at intervals, O-shaped sealing rings 2 and 4 are respectively arranged in the two sealing grooves, and an exhaust hole 3 and a pressing hole 5 are respectively arranged on the peripheral wall of the pipe socket between the two sealing grooves; the wall thickness of pipe socket 6 is 10mm, seal groove bending part radius be 14mm, the interval between the pipe socket inner wall of seal groove top surface and seal groove department is 20mm, the groove depth of seal groove is 10mm promptly. The distance between the central lines of the two seal grooves or the distance between the O-shaped seal rings 2 and 4 is 50 mm. The small distance between the two sealing grooves can cause no flatness between the two grooves, and the shape is difficult to see. The bending radius of the bending part of the sealing groove is less than 14mm, so that the material is sheared during profiling, and even the groove is sheared.
