A, DMF-0.1 type electricMagnetic type gas safety shut-off valve: 
DMF-0.1 type electromagnetic gas safety shut-off valve by the factory production of new product manufacturing. 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 type electromagnetic gas safety shut-off valve is mainly composed of electromagnetic starter and sealing valve good performance combination synthesis. And has the advantages of simple structure, convenient operation, reliable work, cutting speed and good sealing performance. The sealing ring for oil resistant rubber,
Two, DMF-0.1 type electromagnetic gas safety shut-off valve use 
Modern gas industrial furnace fuels are used most low-pressure gas burning, combustion air fan provided by professional. Most of the kiln with air preheating device. In the production process, once the gas pressure is too low, the burning does not work, should be immediately cut off the gas and stop the fan (except in the case of special). This can ensure the safety of production, and the rapid cooling stove. 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 situation has occurred frequently. 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 is overcome this disadvantage, while the cutting speed is much higher than the electric cut-off valve, more in line with the safety requirements. This product is also suitable for other occasions similar requirements.
Three, DMF-0.1 type 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)


Four, DMF-0.1 type electromagnetic gas safety shut-off valve technical specifications:
1, according to the general 220V AC electromagnet, the capacitance is about 220VA (supply can also supply the factory special requirements)
2, the valve nominal pressure is PN0.1MPA.
3, see Table 1 (about the size of the butterfly valve flange is consistent with JB81-59).
4, the cut off time: a second
5, medium temperature: -20~180 degrees.
6, the ambient temperature: -20~60 degrees.
