Description

Multi-stage pressure relief and leakage prevention device

The invention provides a multi-stage pressure relief and leakage prevention device, in particular, a multi-stage pressure relief at the oil seal, oil ring or leakage prevention material during the operation process to reduce the leakage caused by the pressure and save The cost of oil seal, oil ring or leak-proof material replacement, so as to achieve the multi-stage pressure relief function with anti-leakage.

It is known that in pressurized processing equipment, at the transmission structure of the mechanism, in order to avoid leakage due to internal pressure, an oil seal is provided at the linkage to reduce leakage. The oil seal is a common name for general seals, simple It is the sealing of lubricating oil; it is a mechanical component used to seal grease. Oil is the most common liquid substance in the transmission system, and it also refers to the general liquid substance. It will lubricate the components that need to be lubricated and output. The components are isolated so as not to let the oil leak. The seals for static and dynamic seals are called oil seals, which can effectively reduce the leakage when the machine is running. The oil seals are generally divided into single type and assembled type. The assembled type is the skeleton and the lip The mouth materials can be freely combined, and are generally used for special oil seals. The sealing function, characteristics, structure type, working state and sealing mechanism of the oil seal can be divided into various forms and different names, but it is customary to call the rotating shaft lip seal ring Seals for oil seals, static seals and dynamic seals are called The representative form of seals and oil seals is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber. The general oil seal often refers to the TC skeleton oil seal. Although the oil seal has a sealing function, it has been pushed by high pressure for a long time. Extrusion is easy to cause damage to the oil seal. Therefore, in pressurized processing equipment, pressure relief valves are often used to control the upper limit of internal pressure, and the upper limit of pressure is used to select the appropriate oil seal, and the oil seal is regularly replaced, so that the machine is kept in a state that is not easy to leak Especially in filtered water, there is a commercially available equipment that uses pressure stirring to filter water, and absorb impurities in sewage through the filter material, resulting in increased filtration rate and efficiency. According to this, pressurization helps reduce the application time. It is beneficial to reduce the processing time cost. For this reason, the industry often considers pressurized processing in order to effectively reduce the time cost during the manufacturing process, increase production efficiency, and not easily breed bacteria through high-pressure environments, so that it can be used for drinking Water filtration field.
