use:
1. The safety valve is installed on pressure equipment, containers and pipelines as an overpressure protection device. Before the pressure in the system exceeds the allowable value, the safety valve should be sealed reliably without leakage. When the pressure in the equipment or pipeline rises and exceeds the allowable value, the valve shall be automatically opened immediately and then discharged in full to reduce the pressure so as to prevent the pressure of the equipment or the pipeline from continuing to rise; when the pressure is reduced to the specified value, the valve shall be Closes in time and guarantees sealing, thus protecting the safe operation of the equipment.
2. The structure of the safety valve is mainly hammer type, spring type, pilot type (or pulse type). According to the ratio of the maximum opening height of the valve flap and the valve seat diameter, it can be divided into the micro-opening type and the full-open type. In addition, the safety valve is also divided into various types with wrenches and without wrenches, closed and open type.
installation:
1. Spring type safety valve should be installed upright.
2. The outlet of the safety valve should be free from resistance or pressure (ie, back pressure). If a drain pipe is installed at the outlet, it shall be guaranteed not to be less than the outlet diameter of the product.
3. Some safety valves have “wrenchesâ€, and some valve seats have “adjustment ringsâ€, which are used for inspection and adjustment.
