Introduction of fire butterfly valve

At present, fire butterfly valves are widely used, such as general drainage and fire system pipes. In general, such a fire butterfly valve needs to have the advantages of simple structure, reliable sealing, light opening and convenient maintenance. The following is a brief introduction to the fire butterfly valve.

1、 Product features
1. The main characteristics are that the structure is relatively simple, the volume is relatively small, and the weight is relatively light. Because it is mainly composed of only a few parts, its weight is not large in actual use.
2. Because of fire butterfly valve’s relatively light volume and relatively few parts, it is relatively simple to operate even if there is a 90 degree rotation when it is opened or closed.
2、 Good fluid regulation and control characteristics
basically, the thickness of the butterfly plate is the only main force when the medium flows, that is to say, the pressure drop generated by the valve is not large. For the butterfly valve, its wear can be reduced a lot. At the same time, this valve can ensure good fluid regulation and control characteristics, so that the medium flow process will be more smooth.
3、 Scope of use
under normal circumstances, this butterfly valve can be widely used in some industrial occasions such as petroleum, gas, chemical industry and water treatment. This is mainly because it has good flow and pressure, as well as the corrosive requirements of remote control, and it also has good adaptability to high temperature and low temperature. Therefore, even in the cooling water system of a thermal power station, the use of butterfly valves is common.
at present, the fire butterfly valve is widely used. The main material selection is the material selection of the valve body and the valve shaft. In many fire-fighting systems, the valve body must be used to help control the switching state, so the use of butterfly valves can intuitively, clearly and reliably reflect some normal working states of the fire-fighting system. This is a special reason why butterfly valves are widely used.
