Standard for the use of pipe caps

The pipe cap products produced by our company can be pressurized during use, and the safety valve is a kind of overpressure protection device. When the pressure of the equipment exceeds the predetermined value, the safety valve will automatically open and reduce the pressure of the equipment by pressure relief. In the case of pressure below the specified value, the safety valve will automatically close, so as to avoid the loss of media in the equipment. Safety valve in the pressure vessel, pressure pipeline and boiler application more, belong to the automatic valve class. Under normal circumstances, the body of the container is the appropriate installation position of the safety valve, and the installation of liquefied gas in the gas phase part can not be ignored.

Pressure vessels belong to closed equipment, which can carry a certain pressure. They usually contain gas or liquid inside, and metal and non-metal materials are more common. In its internal and external, there is a large pressure difference, which is potentially dangerous. In the process of manufacturing and use, due to the improper design, operation and use behavior, easy to cause accidents, so there are strict requirements in the standard control. Pressure vessels have their own characteristics of use, coupled with the characteristics of the internal medium of the chemical process, it is necessary to install supporting safety accessories, so as to ensure the use of pressure vessels and the normal process of the process. In order to ensure the smooth operation of the pressure vessel, some devices are often installed on the equipment, such as stationary valve, pressure gauge, thermometer, liquid level gauge, emergency cut-off device, bursting disc device, etc. According to the performance and use of the division, commonly used accessories can be divided into 4 types, namely pressure relief device, metering device, alarm device and interlocking device. Among them, the key accessories include pressure relief device, pressure gauge, etc.
