How to check whether the seal of the stainless steel reactor is leaking:
The method of detecting air leakage: pressurize the reactor, let it stand for a period of time, and observe whether the pressure of the pressure gauge drops. If there is no drop, it means there is no leakage; if there is a drop, you need to use foam to drip into the suspicious place, and there is leakage There will be bubbles in the place.
Generally, there are air leaks in the sealing part of the kettle cover and the kettle body, and the joints are leaking. If there is a leak in the seal between the lid and the body of the kettle, you need to replace the sealing ring. Some kettles do not have a sealing ring and are hard sealed. This is more difficult to repair. Once the air leaks, it means that the sealing surface is damaged. service. If the valve joint is leaking, just tighten it with a wrench. If it doesn't work, replace the valve.
Needle valve maintenance, the needle valve may need to adjust the seal after a long time of use, if it is not used for a long time, it should be kept open. The valves on the stainless steel reactor are sealed with double ferrules. In order to increase its service life, please minimize the disassembly of the ferrule nuts at the two ends of the needle valve. If they are disassembled too frequently, they will not be able to ensure a good seal.
Sealing ring maintenance, carefully check the gasket in the kettle cover before closing the body so that it is not damaged. After many experiments, the inner and outer edges of the gasket may squeeze out thin irregular burrs. This does not mean that the gasket needs to be replaced, but a sharp knife is required to remove the flange. Check the joint surface of the kettle cover and the kettle body to make them smooth and free of bulge marks, and then put the kettle cover on the stainless steel reaction kettle.
