The safety protection function of Gate Valve has important applications in our daily lives, especially in boilers. It can prevent excessive medium pressure inside the boiler from causing explosions. Moreover, in places where people gather, the occurrence of explosions will cause Very serious consequences, causing unnecessary personal danger and property damage.
Only the correct use of Gate Valve can ensure real protection. First of all, we need to know that the Gate Valve must have good sealing properties and must be installed vertically. There must be no resistance at the outlet of the Gate Valve so that the Gate Valve can operate normally when it is opened. Secondly, the Gate Valve needs to undergo professional inspections regularly to ensure the safety of the Gate Valve. Effective for long term use.
1. Independent pressure system (separated from other systems with shut-off valve). The system refers to full gas phase, full liquid phase or gas phase communication;
2. When there is no Gate Valve at the source of the pressure material of the container;
3. Containers and pipelines whose design pressure is less than the pressure at the pressure source;
4. Outlet pipelines of positive displacement pumps and compressors;
5. Containers with overpressure due to accumulation of non-condensable gas;
6. If there is a shut-off valve or
Control Valve on the outlet pipe of the heating furnace, a Gate Valve should be installed upstream of the valve;
7. Overpressure parts caused by process accidents, automatic control accidents, power accidents, fire accidents and public engineering accidents;
8. The part where the liquid undergoes thermal expansion due to the closing of the valves at both ends;
9. Steam outlet pipe of the condensing turbine;
Due to the safe and effective protective effect of Gate Valve on some equipment, it has attracted the attention of relevant laws in our country. In the "Safety Law", relevant items have been specially formulated for Gate Valve, indicating that the safety work of boilers, elevators and other equipment must be strengthened. , to ensure the safety of personal and property. Of course, regarding the quality issues of Gate Valve, my country's regulatory authorities have also increased supervision and requirements to ensure that the quality of Gate Valve is qualified, so that the equipment used can play a real safety protection role and reduce the occurrence of accidents.
