Product Description
1. Summary of electromagnetic gas shutoff valve:
Electromagnetic gas cut-off valve is mainly composed of electromagnetic starter and butterfly valve with good sealing performance. The utility model has the advantages of simple structure, convenient operation, reliable operation, fast cutting speed and good sealing performance. Sealing rings are generally oil-resistant rubber, but also can provide high temperature, corrosion resistance, fluorine rubber sealing rings of special products.
2. Technical specification of electromagnetic gas cut-off valve:
1. Electromagnets are generally supplied at 220V AC and about 220VA capacitance (our factory can also supply when special requirements are required).
2. The nominal pressure of the valve is PN0.1MPA.
3. Relevant dimensions of butterfly valves are shown in Schedule 1 (flanges are identical with JB81-59).
4. Cut-off time: one second
5. Medium temperature: - 20-180 C.
6. Ambient temperature: - 20-60 C

3. Use of electromagnetic gas cut-off valve:
Most of the modern industrial kilns fueled by gas use low-pressure gas burners, and air is supplied by professional fans. Most kilns also use air preheating devices. In the production process, once the gas pressure is too low and the burner can not work properly, the gas should be cut off immediately and the converter blower should be stopped (except in special cases). This can not only ensure the safety of production, but also prevent the furnace from cooling rapidly. If the gas is not cut off in time, the gas still has a certain residual pressure. It is possible to enter the air duct through the mixture of burners, especially the air duct with preheating device. As the temperature drops, a certain negative pressure will be formed, which makes it easier for the gas to enter the air duct. Then an explosive mixture will be formed in the air duct or furnace. When ignited again, it will often occur. Cause an explosion and cause an accident. This has happened repeatedly. This product is developed and designed for these situations. It is an ideal equipment which is indispensable for the production safety of various industrial furnaces and kilns using gas as medium.
There are many reasons for the low pressure of gas, including the low pressure of gas caused by power cut-off. Now the general gas cut-off valve is driven by motor, and it can not operate when power cut-off occurs. Therefore, the low pressure of gas caused by power cut-off can not achieve the role of safety protection. This product overcomes this shortcoming, while cutting off speed is much higher than the electric shutoff valve, more in line with the safety requirements. This product can also be applied to other occasions with similar requirements.
