Description

Dry Pantent Assembly {A DRY PENDENT ASSEMBLY}

The present invention relates to a dry pantant assembly, and more specifically, a spring for forcibly lowering a plunger that closes an inlet port when a sensing unit deviates due to a fire is disposed on one side (lower side) of the first housing (the other side) (upper side). While supplying the fire extinguishing water to avoid the interference of the spring, in addition to supplying the fire extinguishing water stably while maintaining a constant flow through the surface by fixing the plunger detached from the inlet 180 degrees by its own weight, The present invention relates to a dry pantant assembly in which a plurality of baffles are formed so as to increase the amount of extinguishing water by eliminating bottlenecks caused by vortex formation.

In general, in order for the fire to proceed continuously, there must be a chain reaction with an ignition source, oxygen, and combustibles. Any one of a combustible material, an oxygen source, or a chain reaction such as blocking the supply of oxygen or blocking the chain reaction of combustion. If it can be eliminated, it will be possible to extinguish a fire. Based on this principle, fire extinguishing equipment for initially extinguishing a fire in a place such as a building or factory is installed and used in a protected object or a protected area.

Existing fire extinguishing equipment directly sprays extinguishing water within the combustion range so that the object to be protected is cooled by the heat of evaporation of the extinguishing water, and at the same time, water system that induces the suffocation effect around the object of protection by water vapor generated as the extinguishing water evaporates. It can be classified as a fire-extinguishing facility and a gas-based fire-extinguishing facility that maintains an oxygen concentration in the combustion range of about 15% or less using an inert gas as an extinguishing agent.

In the case of the above-described water-based fire extinguishing equipment and gas-based fire extinguishing equipment, although there are various types according to the place where they are installed or the type of protection object, in the event of a fire, the fire extinguishing water or extinguishing agent is piped from the storage tank where the extinguishing water or extinguishing agent is stored. By transferring at high pressure, the basic principle of extinguishing water or a fire extinguishing agent through a spray nozzle for extinguishing installed in a protected object or a protected area can be considered to be mostly the same.

In general, a method of spraying extinguishing water or an extinguishing agent is divided into a dry type (also called dry type or open type) and a wet type (wet type or closed type).

In particular, the dry head (dry pantent) is configured such that when the heat-sensitive plate is disengaged by heat, extinguishing water is ejected.

A conventional dry fire extinguishing facility is a "sprinkler head" (Republic of Korea Registration No. 0384962).

The conventional sprinkler head has a problem in that the coil spring is disposed at the lower portion of the inlet hole, thereby preventing the inflow of the extinguishing water and reducing the inflow of the extinguishing water.

In addition, the conventional sprinkler head has a problem in that the inlet volume of the fire extinguishing water is reduced due to a smaller surface of the passage means by the flanger separated from the inlet hole during a fire.
