Embedded-method anti-leakage technology for high-pressure water and gas conveyance

Abstract

The invention relates to an embedded-method anti-leakage technology for high-pressure water and gas conveyance. The embedded-method anti-leakage technology is characterized in that: a steel pipe flange plate connector is adopted, wherein flange plates are hollow cylindrical bodies, each flange plate is equal in thickness and height, the two flange plates are connected with a pipe in a flat welding way, and deletion of a traditional operation procedure for turning ledges of the flange plates is reduced; in addition, a circle of groove is respectively formed on a pair of flange plants at two connectors of a front pipe and a rear pipe in a turning way, a circle of groove is formed only on one flange plate in a turning way when the pressure of conveyed water or gas is smaller than high pressure, and then O-shaped seal rings are embedded into the groove; the seal rings can be customized or self-made, wherein the self-made method of the O-shaped seal rings comprises the following steps of: cutting off a strip-shaped circular plastic rope to form bevels and then gluing, wherein the depth of the groove of each flange plate is 1 / 3-2 / 5 of the diameter of the rope; and the front flange plate and the rear flange plate are connected by bolts. The embedded-method anti-leakage technology can also be used for a pressure pipe of a concrete pressure solution bath, one flange plate with electric welding connection is embedded onto the outer circle of the steel pipe and is then poured into concrete of the pressure solution bath, and therefore the purposes of sealing and anti-leakage can be achieved.

Description

technical field [0001] The invention relates to a leak-proof technology of an embedding method for high-pressure water and gas transportation, in particular to a leak-proof technology of an embedding method for high-pressure water and gas transportation used in high-pressure water and gas transportation of steel pipe flange joints. Background technique [0002] At present, there are many known leak-proof technologies for high-pressure water and gas transmission, such as direct welding, sockets or steel pipe flange joints. Although the former is very good, long-distance direct welding is inconvenient for maintenance. If sockets are used, High-pressure water and gas will leak or even be broken down. The traditional way is to use quick-connect and quick-install steel pipe flange joints. It turns the flange into a shoulder, drills bolt holes around the flange circle, and Place a flat rubber ring between the two flanges, and then tighten the bolts. This flange connection is easy ...

[0002] At present, there are many known leak-proof technologies for high-pressure water and gas transmission, such as direct welding, sockets or steel pipe flange joints. Although the former is very good, long-distance direct welding is inconvenient for maintenance. If sockets are used, High-pressure water and gas will leak or even be broken down. The traditional way is to use quick-connect and quick-install steel pipe flange joints. It turns the flange into a shoulder, drills bolt holes around the flange circle, and Place a flat rubber ring between the two flanges, and then tighten the bolts. This flange connection is easy to disassemble. During high-pressure water and gas transmission, the filler will still leak or be broken down, so the above-mentioned traditional technologies have defects
