This patent provides a variety of parallel schemes, and the different expressions belong to the improved scheme based on the basic scheme or the parallel scheme. Each scheme has its own unique characteristics.

A welding device with pressure leak repair point, characterized in that the welding device includes a cover plate 2, a pressure relief pipeline 5 is connected to the cover plate, the pressure relief pipeline includes an opening and closing valve, and the cover plate can cover On the leakage point of the pressurized fluid pipeline 1. The substantive technical effect of the technical solution here and its realization process are as follows: the pressure leakage repairing device uses an autonomous device to cover the pressure pipeline, releases the pressure through the pressure relief hole, and welds the covering plate to the pressure pipeline. On the pipeline, after the welding is firm, close the pressure relief hole. It is a steel plate made to match the existing pipes according to the curvature of the existing pipes. Its main function is that when the surrounding plate is welded with the existing pipeline, it can be tightly welded. It is generally composed of a ball valve and a steel pipe that matches the nominal diameter of the ball valve, and is welded in the middle of the cover plate before plugging. The essence of this patent is to have a valve or opening and closing device for effective pressure relief and easy closing before repair welding. This paragraph is the first embodiment.

The substantive technical effect and the realization process of the technical solution here are as follows: when releasing pressure, if it is gas, it does not need to be temporarily stored, but if it is liquid, the pressure liquid can be temporarily stored.

Referring to FIG. 3 , this paragraph is the second embodiment, and the cover plate 2 includes a ring of gaskets around the corresponding leakage point. The substantive technical effect and the realization process of the technical solution here are as follows: As a preference, the gasket is preferably made of rubber material, and the welding position is in a circle, so the extrusion of the gasket here can effectively make the Welding proceeds more smoothly.

It can effectively reduce energy consumption and improve maintenance efficiency. It is a good choice for repairing welding leaks under the condition of non-stop production and improving production efficiency.

The present invention is a pressurized leakage repair device, and this technology has the following advantages:

1. No need to stop production, on-site production, convenient and simple. 2. This patent solves the need to stop production during repair welding of hot-pressed pipelines, and provides an effective solution.
