Description
Technical Field
The utility model relates to a main steam pipeline leakage repairing device, and belongs to the technical field of pipeline repairing.
Background
In production, the phenomenon of steam pipeline breakage and air leakage is found in a chemical pulp workshop, if the chemical pulp workshop is not repaired, the air leakage can lead to pipeline corrosion, the air leakage phenomenon can become more serious, the risk of pipe explosion exists at any time, and the repair is needed in time. Because the steam pressure of the steam pipeline leakage position is high and the leakage area is large, the shutdown and the gas stopping are required when the steam pipeline leakage position is repaired, so that the safety and the repairing effect of constructors are ensured. However, once the workshop is stopped and the gas is stopped, huge manpower and material resources are consumed for restarting, the production efficiency is reduced, and the production cost is increased.
Therefore, a way of timely repairing the gas without stopping the gas is needed under the premise of ensuring the safety of operators.
Disclosure of Invention
The utility model aims to solve the technical problems that: overcomes the defects of the prior art, provides a main steam pipeline leakage repairing device, realizes the repair of the leakage position of a damaged pipeline under the condition of no shutdown, ensures the safety of operators, improves the repairing efficiency and reduces the production cost.
The utility model relates to a main steam pipeline leakage repairing device, which comprises a sleeve, wherein the sleeve is sleeved on the periphery of a main steam pipeline leakage part, the sleeve comprises a first part and a second part which are symmetrically arranged, the first part and the second part are butted to form a cylinder with a hollow inside and notches arranged at the top and the bottom, and the size of the notch is matched with the external size of the main steam pipeline.
The periphery of the sleeve is provided with an exhaust valve. When the sleeve is installed, the main steam pipeline still leaks air, so that air stays in the sleeve to influence the installation of the sleeve, and when the sleeve is installed, the exhaust valve is opened, steam is discharged, and the sleeve is convenient to install.
The bottom of the periphery of the sleeve is provided with a drain valve. Because main steam pipeline still is leaking gas, so can form the water droplet at the sleeve pipe, influence the installation of sleeve pipe, when installing the sleeve pipe, the drain valve is opened, discharges liquid water, the installation of the sleeve pipe of being convenient for.
The periphery of the sleeve is provided with an insulating layer. After the sleeve is installed, the space between the sleeve and the main steam pipeline is filled with steam in the main steam pipeline, and an insulating layer is arranged on the periphery of the sleeve to ensure that steam heat cannot be lost.
The sleeve is made of carbon steel. The carbon steel has high strength and good corrosion resistance, and when high-temperature steam is filled between the sleeve and the main steam pipeline, the sleeve is not easy to deform.
The butt joint of the first part and the second part is fixedly connected in a welding mode. The air tightness of the sleeve is ensured by the welding mode.
Compared with the prior art, the utility model has the beneficial effects that:
(1) According to the utility model, under the condition of no shutdown, the repair of the leakage position of the damaged pipeline is realized, the safety of operators is ensured, the repair efficiency is improved, the production cost is reduced, and the pipeline at the repair position is more attractive.
(2) An exhaust valve is arranged at the periphery of the sleeve. When the sleeve is installed, the main steam pipeline still leaks air, so that air stays in the sleeve to influence the installation of the sleeve, and when the sleeve is installed, the exhaust valve is opened, steam is discharged, and the sleeve is convenient to install.
(3) The bottom of the periphery of the sleeve is provided with a drain valve. Because main steam pipeline still is leaking gas, so can form the water droplet at the sleeve pipe, influence the installation of sleeve pipe, when installing the sleeve pipe, the drain valve is opened, discharges liquid water, the installation of the sleeve pipe of being convenient for.
