QUICK RESPONSE SPRINKLER HEAD WITH IMPACT-RESISTANCE AND EARTHQUAKE-PROOF}

The present invention relates to an early reaction sprinkler head having impact resistance and shock resistance, and more particularly, to prevent damage to the thermal part while preventing the opening of the drain pipe even when an external shock or vibration occurs. It relates to a shock- and shock-resistant early reaction sprinkler head made.

Generally, when building a building, various building facilities are installed together, and these building facilities are various, such as electric equipment, water supply and drainage equipment, gas equipment, air conditioning equipment, and fire extinguishing equipment.

In addition, with the advancement of building technology, new building equipment methods continue to be developed and applied. In recent years, the importance of building equipment in the whole building is increasing, and the cost of building equipment costs is higher than the total cost of building construction.

Among these building facilities, fire extinguishing equipment is one of the most important building equipments, and there are various types and most commonly installed, and sprinkler is known to extinguish fire by releasing water in case of fire. This sprinkler is a kind of automatic fire extinguishing equipment. The sprinkler head is connected to the drain pipe installed at the ceiling of the building at regular intervals and the drain pipe is installed in connection with the water supply.

When the sprinkler head is flamed and the temperature inside the building rises, the heat sensing unit constituting the head detects it, and when the temperature rises above a predetermined temperature, the heat sensing unit dissolves or ruptures and continues to pressurize the water in the drain pipe. It is designed to extinguish a fire automatically by releasing it.

Sprinkler heads are largely classified into a frame type and a flush type. In most cases, a glass bulb is used as a heat sensing unit and a flush link is used as a flush type.

The sprinkler head is configured such that in the case of the frame type, the holder supported through the glass bulb normally closes the waterproof port, and in the case of the flush type, the deflector supported through the metal fusible link melted at a predetermined temperature closes the waterproof port. do.

Such sprinkler head, when a heat source and hot air is delivered to the heat sensing unit due to a fire, the liquid inside the glass bulb expands and ruptures the glass bulb or dissolves the fuseblink to release the water by opening the waterproof hole. Extinguish fire.

However, the sprinkler head of the prior art has a frame type made of glass bulbs, which protrudes from the ceiling surface and hurts aesthetics, and is likely to be deformed or damaged by hitting furniture or office appliances, and the heat sensing portion is made of a fuzzy link. In the case of the flush type, there is a risk of malfunction due to softening of the fuseblink due to temperature change, and the early melting is difficult due to the slow melting speed of the fuseblink made of a low melting point alloy.

Recently, an early reaction sprinkler head has been proposed to solve the above disadvantages and minimize the height protruding from the ceiling, and to open the sprinkler head quickly in response to a temperature change in the event of a fire.

This early reaction sprinkler head has a flush-type shape and has a relatively simple structure, and the heat sensing unit is provided with a glass bulb which reacts early (close to 50 RTI of response time index) near the set temperature. As soon as the glass bulb is destroyed, the head is opened and the digestive water is discharged.

However, since this early reaction sprinkler head does not consider external shocks or vibrations, it is not fixed at the assembled position due to shocks or vibrations after installation. There is a problem. Since the conventional sprinkler head maintains the assembled state while receiving the assembled load, there is a possibility that play occurs between the parts due to the assembly load in shock or vibration.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is to open the drain pipe while preventing the breakage of the glass bulb even if external shock or vibration occurs before, during or after installation Another object is to provide an impact and shock resistant early reaction sprinkler head which is designed to prevent a gap from occurring.
