The situations and features of rapid cut-off valve is mainly used

Fast shut-off valve is normally open type pulse trigger type solenoid valve. Shanghai walter bracket valve production rapid cut-off valve structure simple, responsive, reliable operation, accident characteristics of self-locking and manual reset function has been used in all walks of life. Mainly concentrated in the following aspects: 1, valves in daily work in a normally open state, the electromagnetic valve coil is in power position, don't waste electricity. 2, when the accident happened, the valve coil instantaneous electricity, trigger quick off valve, the state of self-lock. Then the power even removed, the valve is still in the state of self-locking, does not automatically open again. 3, adopt pilot operated valve disc, open easily, even pressure 6 bar open is very relaxed, diameter greater than DN125, adopts the lever handle, valve, a switch and effort. Is mainly used in the following situations: 1, connected with combustible gas leakage monitoring instrument, the instrument to detect combustible gas leakage, the main air valve automatically shut down, cut off the gas supply, in a timely manner to prevent malignant accidents. 2, and the limit of thermal equipment, temperature and pressure safety controller connection when the temperature of the equipment within the testing point pressure exceeds the limit of the set value, automatic quick close the gas supply valve, stop the supply of fuel. 3, and in the middle of the high-rise building fire alarm system, when building fire, cut off the gas inside the building, to prevent the occurrence of gas explosion. 4, or factory in the city gas supply network ZCR gas emergency shut-off valve is installed inside, can be in the central control room centralized control, emergency shut down the scene of the accident of pipeline gas supply remote control.
