The role of safety valve in mining machinery and equipment is mainly reflected in the following aspects:
First, the core function: pressure control and relief
Overpressure protection
When the pressure in the equipment or pipeline exceeds the set value, the safety valve will automatically open, and the pressure will be reduced to a safe range by discharging medium (such as gas or liquid) to prevent equipment damage or explosion accidents caused by overpressure.
Prevent blasting risk
In the emergency of abnormal pressure rise, the safety valve can quickly release the pressure, so as to avoid the system from cracking due to excessive pressure and ensure the safety of equipment and personnel.
Second, extended functions: system stability maintenance
pressure balance
By accurately controlling the discharge capacity, the safety valve can maintain the system pressure in the best working range and ensure the normal operation of the equipment.
Prevent the accumulation of hazardous media.
For the equipment that stores or transports flammable and explosive media (such as fuel and gas), the safety valve can eliminate excessive media in time to reduce the risk of fire or explosion.
Third, the application scenarios and importance
Applicable equipment: mainly installed on pressure-bearing equipment such as boilers, pressure vessels, pipelines and lifting machinery, such as fuel storage tanks and transportation pipelines in mines.
Safety grade: It belongs to automatic valves and needs regular maintenance and calibration to ensure its sensitivity and reliability.
Regulatory requirements: In high-risk industries such as mines, safety valves are mandatory safety accessories, which meet the national safety production standards.
Fourth. Supplementary explanation of special safety valves
Hydraulic safety valve: pressure is controlled by sealing liquid, which is suitable for high temperature and volatile medium environment. The opening height is divided into micro-opening type and full-opening type.
