1, uses and performance specifications:
This valve is a security valve, installed in the liquefied petroleum gas storage station, liquid and gas pipeline, and the remote hand pump (SB03-175 type) supporting the use of hydraulic control valves used to open - close to in the pipeline or tank leak or fire occurs when a large number of fast hand to hand pumps, pressure relief, or high temperature to melt fusible alloy, and the automatic pressure relief valve cylinder, the rapid closure of the Stop-leak valve, from the security effect.
Second, more than double oil pump control valve works
More than two emergency shut-off valve control using two hand pumps, in which a work of the other pump spare pump to prevent pump damage to the valve does not work, respectively, each with an emergency shut-off valve (J23H-40P) needle valve control. (Note: See photos connected with the storage 3)
3: The main performance specifications
20K 4.0MPa pressure cylinder working pressure rating ≤ 6.0.Mpa
Operating temperature -40 ~ +80 ℃ medium mixing tank using spindle oil, transformer oil
Use medium natural gas, liquefied petroleum gas, liquid ammonia melting closed time ± 70 ℃
Closing time ≤ 10 seconds to open the pressure ≥ 2.0MPa Cylinder
4: storage installation note:
1, will keep all the external channel of the valve with plug or cover closed, stored in a dry and ventilated room, a long-term storage should be inspected regularly to remove dirt, rust and oil in the processing surface coating to prevent corrosion.
2 Install this valve should be cleaned before and will tighten the screw joints.
3, the valve with check valve principle, only one would like to cut, install the valve must pay attention to signs, to one end of a valve to protect the entrance.
4, order must specify the form of flange sealing surface, pressure rating and connection standards.
