Description

Outdoor fire hydrant with a structure that fully opens the valve

The present invention relates to an outdoor fire hydrant with a fully open valve structure, and more particularly, to an outdoor fire hydrant with a fully open valve structure that can have a structure to guide the user to completely open the valve of the outdoor fire hydrant.

In general, outdoor fire hydrants are one of the main products used for outdoor fire extinguishing facilities by connecting a fire hose and a pipe window. , are installed in company buildings and apartment houses.

If the initial fire suppression fails in the case of a fire in the above-mentioned place, toxic gas due to a large fire is spread to the surrounding area at the same time as loss of life, which may seriously affect the environment and the ecosystem.

Therefore, the purpose of the installation of outdoor fire extinguishing facilities is to extinguish fire and to prevent expansion of combustion, not only for initial fires, but also for medium-term fires. It should be designed so that stable pump efficiency can be maintained by reducing the internal pressure loss.

However, while using the outdoor fire hydrant, the user does not open the valve rod of the outdoor fire hydrant completely, and the area where the internal disk and fire water collide remains large. will lower

In addition, as the internal disk of an outdoor fire hydrant that is not fully opened and the fire water collide, the disk and packing are rapidly worn, shortening the lifespan, and as the replacement time of the outdoor fire hydrant is accelerated, replacement costs and environmental problems due to waste generation will do

In addition, in the situation where the residual fire water is discharged after using the outdoor fire hydrant, various factors cause the soil to flow back into the outlet, causing corrosion as the soil flows into the outdoor fire hydrant.
