Brief introduction of DMF-0.1 electromagnetic gas safety shut-off valve: 
DMF-0.1 electromagnetic gas safety shut-off valve produced by our factory new generation of products. Electromagnetic gas safety shut-off valve not only overcomes the common electric cut-off valve cut off the disadvantages of slow speed, complex control, and can immediately cut off the gas in power, to ensure the safety of production.
DMF-0.1 electromagnetic gas safety shut-off valve is mainly composed of electromagnetic starter and butterfly valve with good sealing performance. It has the advantages of simple structure, convenient operation, reliable operation, fast cutting speed and good sealing performance. The sealing ring is generally oil resistant rubber,
Two, DMF-0.1 electromagnetic type gas safety shut-off valve use 
Most of the modern industrial furnaces using coal gas as fuel are low pressure gas burners, which provide combustion air by professional fans. Most kilns also use air to heat devices. In the production process, once the gas pressure is too low, the burner can not work properly, should immediately cut off the gas and stop the fan, except for special cases. This ensures the safety of production and does not make the furnace rapidly cool down. If the gas failed to cut off the gas, there is a certain pressure, possibly by mixed gas burning nozzle into the wind pipe, in particular to a wind pipe heating device, the temperature drop will form a negative pressure, make it easier for the gas into the air duct, and then form a mixture of explosive in the wind pipe or furnace. When the ignition will often cause an explosion, causing the accident. This has happened repeatedly. This product is for the design and development, is the ideal equipment for various industrial furnace gas production safety as the indispensable material.
Gas pressure for many reasons, including low gas pressure due to power outages, the current gas shut-off valve is driven by the motor, power cannot action, so the gas pressure caused by power outages, can not achieve the safety protection. This product overcomes this shortcoming, and the cutting speed is much higher than the electric shut-off valve, which is more in line with the safety requirements. This product can also be used in other occasions with similar requirements.
Three, DMF-0.1 electromagnetic gas safety shut-off valve structure and working principle
DMF-0.1 type electromagnetic gas safety shut-off valve by valve, air tightness high traction electromagnet, a lever device, a locking pin, hammer and spring structure, the structure and working principle (see Figure 1)


Technical specifications of four and DMF-0.1 electromagnetic gas safety shut-off valve:
1, electromagnet according to AC 220V, the capacitance is about 220VA supply (special requirements, the factory can also supply)
2. The nominal pressure of the valve is PN0.1MPA.
3, butterfly valve size see Table 1 (flange and JB81-59 consistent).
4, cutting time: one second
5, medium temperature: -20~180.
6. Environmental temperature: -20~60.
