Description
Technical field
The utility model belongs to a kind of valve, particularly the pneumatic protection cut-off valve that extinguishes of band warning output.
Technical background
In rock gas gas production production process, rock gas negative-pressure firing oven is widely used.The rock gas gas gathering station will also use the negative-pressure firing stove to the rock gas heating back throttling step-down of well head extraction in the rock gas TEG Dehydration Processing.The negative-pressure firing stove of gas gathering station adopts injection type negative-pressure firing device, and fuel gas is rock gas.Injection type negative-pressure firing device is to utilize the suction force air feed that hot gas rises in the oven chimney without the special fan air feed.Structurally, injection type negative-pressure firing device has two fire to chew: main Huo Zui and an ever-burning flame (female fire) fire are chewed, and the ever-burning flame fire is chewed once lighting and do not allowed to extinguish, and such flammule needs is round-the-clockly firing reliably.The fuel gas that main fire is chewed is subjected to the controlled supply of thermostat valve, when the medium temperature that will heat in the stove is lower than setting temperature, temp controller is opened thermostat valve automatically, (0.1MPa) with pressure rock gas flows to main fire by thermostat valve and chews, lighted medium heating in the oven by ever-burning flame, after medium was heated to setting temperature in the stove, temp controller was closed thermostat valve automatically, main fire is chewed fuel gas and is cut off, and main fire extinguishes and stops heating.Cause the accident for preventing that ever-burning flame from extinguishing, natural gas negative-pressure firing device all is furnished with the blowout protection valve.
Rock gas negative-pressure firing oven adds heat control and blowout protection adopts pneumatic controller, establishes thermostat valve and blowout protection valve on the fuel gas supply pipeline, and thermostat valve is accepted the temp controller control signal and opened and closed automatically; The blowout protection valve is to cut off as the pneumatic control signal that blows hard or accept flame detector after ever-burning flame extinguishes during other faults fuel gas with fuel tube at severse weather, thermostat valve is opened is laggardly become owner of natural gas that fire chews and can not be lighted and cause the accident in order to avoid ever-burning flame extinguishes temp controller when medium temperature reduces in the stove of back.
The shortcoming of this natural gas negative-pressure firing device blowout protection valve is to send alarm signal for after the blowout protection valve cuts out the control room, send alarm signal and need install pressure transmitter or pressure switch additional, increases cost.
