Abstract

The invention discloses a PE ball valve provided with a metal insert, and belongs to the field of gas transmission. The PE ball valve includes a valve body, a valve core, the metal insert, a torsion shaft pin, a torsion shaft pin seal ring, a support and a support seal ring; a valve seat is arranged at the center of the valve body, a port in the vertical direction of the valve body is used for accommodating the torsion shaft pin, and the metal insert is arranged in a port in the horizontal direction of the valve body; the torsion shaft pin seal ring is arranged at a position where the torsion shaft pin and the valve body are contacted; the support is arranged between the valve body and the valve core and is used for mounting the support seal ring; and the support seal ring is arranged at a portion wherein the valve body and the valve core are contacted. According to the embodiment of the invention, a PE ball valve structure provided with the metal insert is connected on a diffusing pipe, so that the leakage problem in steel and plastic conversion and thread connection between steel valves or copper valves in the prior art can be solved, potential safety hazards like fire and explosion caused by leakage are eliminated, and further the safety of the whole gas transmission system is improved.

Description

technical field [0001] The invention relates to the field of gas transmission, in particular to a PE ball valve with a metal insert. Background technique [0002] At present, buried polyethylene (PE) pipes are usually used in gas transmission systems. Among them, the ball valve connected to the upper part of the relief pipe on the relief ball valve is usually a steel valve or a copper valve. The installation effect of the steel valve or copper valve determines whether it is safe or not. . [0003] At present, the installation process of the steel valve or copper valve is as follows: First, the plastic end of the steel-plastic conversion joint is welded on the upper part of the discharge pipe through the PE electrofusion sleeve, and then the steel end of the steel-plastic conversion joint is connected to the steel valve or copper valve through threads. . [0004] In this structure, the threaded connection between the steel-plastic conversion joint and the steel valve or cop...
