Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire sprinkling, in particular to a thermal induction type fire sprinkling head. BACKGROUND

[0002] The thermal induction type fire sprinkling head is a common indoor fire-fighting equipment, usually uses a glass tube to support the closed assembly of the water outlet, and an organic solution that expands after being affected by high temperature is installed in the glass tube. When a fire occurs, the indoor temperature rises, causing the organic solution to expand after thermal induction, and the closed assembly of the sprinkling head is released after the glass tube expands and bursts, so that the sprinkling head can automatically sprinkle water through thermal induction. A sprinkling head for indoor fire-fighting is disclosed in Chinese Patent No. 202210458557.4, which comprises a threaded mounting head and a bottom plate. The threaded mounting head is fixedly provided with a fixed frame at the lower part, and L-shaped rods are fixedly arranged on both sides of the lower part of the fixed frame. A support seat is arranged between the lower ends of the two L-shaped rods, and a lap joint groove is formed in the upper part of the support seat. A bottom support is placed in the lap joint groove. A sealing plug is arranged at the inner lower end of the threaded mounting head, and a top support is arranged at the lower part of the sealing plug. A glass tube is arranged between the top support and the bottom support. The vertical parts of the two L-shaped rods are hollow structures, and sliding columns are slidably arranged in the vertical parts of the two L-shaped rods. The lower ends of the two sliding columns pass through the outer walls of the lower parts of the L-shaped rods and are fixedly arranged on both sides of the upper part of the bottom plate. The present application changes the sprinkling range by lifting and moving the splash plate, realizes larger range of sprinkling and fire extinguishing, and makes the water flow directly act on the upper part of the splash plate without obstruction, thereby improving the water flow utilization.

[0003] The comparative document only solves the problems of small sprinkling range, low water flow utilization, and small water splashing range of the existing indoor fire sprinkling head. However, when a fire occurs, the range of water splashing cannot be changed by simply lifting and moving the splash plate, which is insufficient for large-scale sprinkling. The existing fire sprinkling head, such as the downward type sprinkling head, is usually installed at a high position. When the sprinkling head starts to sprinkle water, the water will fall slowly due to the high height, resulting in small water pressure and small diffusion range, and poor fire retardant effect.

Because the internal air pressure of the air cylinder 309 is less than the external air pressure, the air inlet valve 312 in the air inlet pipe 311 moves toward the air cylinder 309, and the air outlet valve 315 in the air outlet pipe 314 moves away from the air cylinder 309.
