Abstract
The utility model provides a GIL gas sweeps special connecting tube, includes straight tube section, and straight tube section one end is fixed with standard pipeline flange, and the straight tube section other end is connected with the diffusion section, and the diffusion section other end is fixed with the first flange that matches with GIL hand hole, and first flange is connected with GIL. The connecting pipeline special for GIL gas purging provided by the utility model is convenient for GIL gas purging operation.
Description
Technical Field
The utility model relates to a connecting pipeline, in particular to a connecting pipeline special for GIL gas purging.
Background
GIL, gas insulated metal enclosed transmission line. The patent with the application number of 202111609929.0 is a gas purging and cleaning system and method for a gas-insulated power transmission line, which is a patent applied before the company, namely, the interior of the GIL is cleaned through purging equipment. When installed, the purge cleaning system requires an external conduit to be connected to the piping of the GIL through which an external air source is introduced into the GIL. The external pipeline generally needs to purchase standard pipeline, but because the pipeline of the GIL is generally larger, and the conventional standard pipeline is smaller, no connecting pipeline for directly connecting the GIL with the standard pipeline exists in the prior art.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide the connecting pipeline special for GIL gas purging, which can conveniently and directly connect the GIL with a standard pipeline, is convenient for forming a gas path and is convenient for performing GIL purging operation.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a GIL gas sweeps special connecting tube, includes straight tube section, and straight tube section one end is fixed with standard pipeline flange, and the straight tube section other end is connected with the diffusion section, and the diffusion section other end is fixed with the first flange that matches with GIL hand hole, and first flange is connected with GIL.
And the first flange inner ring is provided with a sealing ring groove.
The utility model relates to a connecting pipeline special for GIL gas purging, which has the following technical effects: by arranging the diffusion section matched with the GIL, the connection with the GIL is convenient; through setting up straight tube section, the convenience is direct to be connected with standard pipeline like this, realizes the connection transition of GIL and standard pipeline, conveniently forms effective gas circuit to carry out the gas purging operation of GIL.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a front view (first type) of the present utility model.
Fig. 2 is a cross-sectional view at B in fig. 1.
In the figure: straight pipe section 1, diffusion section 2, first flange 3, sealing ring groove 301, standard pipeline flange 4.
Detailed Description
As shown in figures 1-2, the connecting pipeline special for GIL gas purging comprises a straight pipe section 1, one end of the straight pipe section 1 is connected with a standard pipeline flange 4, the other end of the straight pipe section 1 is connected with a diffusion section 2, the diffusion section 2 is horn-shaped, and the diameter of the diffusion section 2 is larger towards the outer side. The diffusion section 2 other end is fixed with the first flange 3 that matches with the GIL hand hole, and first flange 3 end car has sealing washer groove 301, and sealing washer groove 301 is used for embedding the sealing washer, improves the leakproofness to make this pipeline can be used to the area and press the environment, increased the function of using of this special pipeline.
The standard pipeline flange 4 can be correspondingly connected with a standard pipeline, and the pipeline is used for inputting a gas source or connecting with other equipment on a purge gas pipeline. The air source enters the device through the standard pipeline, and then enters the GIL through the device, so that the GIL is conveniently purged.
Because the standard pipeline is more than one specification, two groups of branch pipe interfaces perpendicular to the axis can be arranged on the straight pipe section 1, and a second flange is arranged at each group of branch pipe interfaces. The diameter of each group of branch pipe connectors corresponds to one standard pipeline, and each group of second flanges is one standard pipeline flange. Thereby facilitating connection with different standard pipes. The first flange 3 and two sets of second flange department form three air inlets, and after the air inlet of arbitrary department and standard pipeline connection, other two air inlets pass through sealing washer, closing plate connection shutoff. Through setting up multiunit branch pipe interface on straight tube section, the convenience is matchd with different standard pipelines like this, improves the commonality of device, strengthens the usability of device.
