Ammonia gas hydraulic cut-off valve is a new type of dangerous goods safety valve, mainly used in emergency situations can quickly close the storage tank entrances and exits, installed in the liquefied gas. Liquid ammonia and gas-related pipeline, and long-range hand pump (SB03-175 type) supporting the use of hydraulic control valve on-off, in order to produce large leaks in pipelines or tanks and even fire, the rapid manual to make Hand pump pressure relief, or high temperature fusible alloy melt, and the valve cylinder automatic pressure relief, the valve quickly closed and only leakage, play a safety role. Ammonia hydraulic shut-off valve works: pipe installation of more than emergency shut-off valve should be used two hand pump control, one of the pumps work another pump spare to prevent the pump damage to the valve does not work, Each emergency shut-off valve with a (J23H-40P) needle valve control. Ammonia hydraulic shut-off valve installation and use of precautions: 1, the custody of the valve of the various external access with a plug or cover closed, stored in a dry and ventilated room, long-term storage should be checked regularly to eliminate dirt and processing surface Apply anti-rust oil to prevent corrosion. 2, the valve should be cleaned before installation, tighten the screw connections. 3, ammonia hydraulic cut-off valve using check valve principle, can only want to cut off, the installation must pay attention to the valve logo, the valve to be protected as the entrance. Valve installation should pay attention to: high and low out. 4, ordering must be marked flange sealing surface form, pressure rating and connection standards.
