Set the safety valve should note the following: (1) there is gas in the container, when the liquid two-phase material safety valve should be installed in the gas phase portion. (2) safety valve for venting flammable liquid outlet valve of the tank should be connected to the accident. When the discharge of the material is a high temperature fuel, its receptacle should be a corresponding protection facilities. (3) general safety valve may be vented, vent should be above the fire place operator 1 meter (m) or more and not towards the 15 meters (m) or less, emitting sparks locations and high-temperature equipment. Indoor equipment, safety containers should lead roof vent and roof above two meters (m) or more. (4) when the inlet valve has cut off valves, isolation valves should be in a normally open state A28H with handle safety valve, and to be sealed in order to avoid mistakes. Spring safety valve opening, closing operation is medium pressure change and the spring preload to its inlet end of the spool to automatically open and close. When the medium pressure (internal pressure) rises to the lifting force is larger than the spring preload, the spool against the spring preload A28H automatically open safety valve with handle quotes, venting excess media, the internal pressure drop, Also, because the spring force, when the internal pressure dropped to a safe value, the spool valve is automatically closed, the discharge stops. Import and export pipeline safety valve (1) and the boiler or pressure vessel safety valve between the connecting pipe and fittings through-hole, and its cross-sectional area of ??not less than the cross-sectional area of ??the valve imported; if you share a few safety valve inlet pipe when A28H security valves, flow sectional area of ??the inlet pipe is not less than the cross-sectional area of ??the safety valve of the import and. (2) the use of a spring-loaded safety valve threaded connection, to connect with a short pipe with threaded pipe and simplified and short inter-header to be welded connections.
