Embodiment 1

[0031] The invention relates to an installation method of electric control lines, which is used for installation and layout of electric control lines and lines in weak current hydropower projects, so that the electric control lines and lines are passed through PVC pipes. The method comprises the steps of repeatedly completing the following steps in a cycle: connecting multiple threaded PVC pipes to form a combined PVC pipe, and passing the electrical control line through the combined PVC pipe; when encountering a non-linear PVC pipe , installed separately and passed through separately; among them, such as Figure 1~Figure 5 As shown, the PVC pipe includes: a pipe body 1; a first externally threaded joint 2 disposed at one end of the pipe body 1; a second externally threaded joint 3 disposed at the other end of the pipe body 1, Wherein, the length of the second externally threaded joint 3 is less than the length of the first externally threaded joint 2; the internally threaded ...

Abstract

The invention discloses an electrical control line mounting method comprising the following steps in cycles: connecting a plurality of thread type PVC pipes so as to form a combined PVC pipe, and enabling the electric control line to penetrate the combined PVC pipe; singly mounting and penetrating when a non-linear type PVC pipe is met. The electrical control line mounting method in circuit engineering complies with an acceptance standard of the weak current water power engineering, and can fast realize jointing; the method connects the plurality of threaded type PVC pipes so as to form the combined PVC pipe, and enables the electrical control line to penetrate the combined PVC pipe; the method performs single mounting and single penetration when the non-linear type PVC pipe is met.

Description

technical field [0001] The invention relates to the field of weak water and weak electricity, in particular to an installation method of an electric control line. Background technique [0002] PVC pipe (PVC-U pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and is extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture. There are several acceptance criteria in weak current hydropower projects, one of which is the requirement for circuit engineering that all electrical control lines and lines must wear PVC pipes. [0003] In order to facilitate the installation of long electrical control lines, the prior art uses rigid connectors and threaded connectors at both ends of the PVC pipe body. During installation, it is only necessary to screw the threaded connectors of the PVC pipe The length of the pipe ...
