A leak repairing structure of a gas cabinet and a leak repairing method thereof

Abstract

The invention relates to a gas cabinet leakage point repair structure. The structure comprises a gas cabinet and a repair template fixedly installed at a gas cabinet leakage point. The repair template comprises a repair template body, 2-8 through holes with the diameter being 4-8 mm are formed in the repair template body, one side face of the repair template body is evenly coated by a silicon rubber layer, and the thickness of the silicon rubber layer which is primarily solidified is not smaller than 10 mm; installation holes are machined in the positions, corresponding to the through holes in the repair template body, around the gas cabinet leakage point, bolts are assembled in the installation holes, and the repair template and the gas cabinet are connected in a sealed mode; a flexible reinforcing metal screen is attached to the outer surface of the repair template body. The invention further provides a method for repairing the gas cabinet leakage point by means of the repair structure. The structure and the method have the advantages that the structure is simple, installation and use are convenient, work efficiency is improved, risks are reduced and performance is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of safe use and maintenance of gas cabinets, and in particular relates to a gas cabinet leak repair structure and a leak repair method thereof. Background technique [0002] The gas tank is a device for storing gas, generally as small as 250m 3 , up to 30000m 3 , is a buffer device for gas users (residents, production equipment) and gas production equipment (gas furnace), which is equivalent to the role of a reservoir. It is usually composed of a water tank, a bell jar, and a middle section. The bell jar and the middle section are automatically adjusted according to the gas production situation of the gas production device and the gas consumption of the gas user. Function, whether its operation is normal or not is not only directly related to the production continuity of the whole system, but also closely related to the personal safety of the vast number of production employees and the people.

Problems solved by technology

[0006] Existing problems and defects in the traditional leak repair method: 1. Electric welding and welding need hot fire, which has great safety risks. The requirements for the content of the system components are extremely strict, and the oxygen content must be at an extremely low level, and it must be continuously controlled online , the welding repair process must ensure that the leak point of the gas cabinet is at a suitable height, and the whole system needs to be in a tense state for a long time. The environment where the gas cabinet is located is humid, and the welder has the risk of electric shock. Tissue deterioration occurs, which intensifies the damage of the gas cabinet. At the same time, when the 8000°C weld encounters the water in the gas cabinet, new stress will be generated, forming a hidden danger of damage again; the drainage welding repair will also be on the relatively flat surface of the gas cabinet Form a certain protrusion, if its size is not well controlled, or the technical size of the gas cabinet is not well controlled, it may hinder the normal operation of the gas cabinet; The time window is very narrow, the requirements for surface treatment are strict, and the on-site environment is very unfavorable to surface treatment. The maintenance time after repair is often short, and the effect is only about one month.

In particular, the quality of materials such as repair agents is not intuitive, and it is difficult to find material quality problems in advance

The quality of the material is crucial to the durability and even the success rate of the repair; 3. The reinforcement of the mechanical fixture requires a large gap (can be inserted into the T-bolt), which has great limitations and will also be compared A certain protrusion is formed on the flat surface of the gas cabinet. If the size is not well controlled, or the technical size of the gas cabinet is not properly controlled, it may hinder the normal operation of the gas cabinet. At the same time, because the rubber is not very elastic, the gas The flatness of the cabinet wall cannot be very good, and it is difficult to achieve a perfect degree of repair
