Embodiment 1

[0021] see figure 2 , a fire sprinkler head with an alarm function, comprising a base 1, a choke arm column 2 is fixedly connected to both sides of the bottom end of the base 1, and a splash plate 3 is fixedly connected to the bottom end of the choke arm column 2, The top of the splash plate 3 is fixedly installed with a glass tube 4, the top of the glass tube 4 is fixedly connected with a mounting seat 5, and the top of the mounting seat 5 is fixedly connected with a sealing plug 6, and the mounting seat 5 and the sealing plug 6 are used to connect the base 1 The bottom end is blocked. Inside the base 1, there is an air intake channel 7 that communicates with the inside and outside, and the air intake channel 7 is inclined from top to bottom, and an air shock channel 8 is opened on one side of the base 1, and the air shock channel 8 is used to communicate with the intake air. The lumen of channel 7 and the external environment. When the mounting seat 5 is pressed against b...

Embodiment 2

[0023] see Figure 3-4 , a fire sprinkler head with an alarm function, the difference from Embodiment 1 is that the air intake passage 7 and the air shock passage 8 are arranged in parallel, the air intake passage 7 and the air shock passage 8 are connected through the air shock chamber 9, and the air shock passage The interior of the shock chamber 9 is provided with a reed 10, the inner bottom of the base 1 gradually increases in diameter from top to bottom, the shape of the sealing plug 6 is adapted to the shape of the inner cavity of the base 1, the air intake channel 7 and the gas shock channel 8 are located at different inner diameter sections of the base 1 respectively.

[0024] As the water flow in the base 1 is sprayed down from a small diameter to a large diameter, the flow velocity decreases, thereby reducing the pressure, which makes the air pressure in the air intake channel 7 and the air shock channel 8 unbalanced, and the air flow will appear due to the imbalance...

Embodiment 3

[0027] see Figure 5 , a fire sprinkler head with an alarm function, the difference from the second embodiment is: the shape of the inner bottom of the base 1 in the second embodiment is inverted, in order to achieve the blocking effect of the air intake channel 7, the air intake channel The lower port of 7 is provided with a sealing plug 11, and meanwhile, the sealing plug 11 is fixedly connected to the top of the sealing plug 6 by a string, so that when the sealing plug 6 comes off, the sealing plug 11 is driven to come off.

[0028] The shape arrangement after inversion can make the water flow change from a large diameter to a small diameter during the falling process, and the flow speed is accelerated, so that the pressure is significantly reduced, the pressure difference becomes larger, the vibration response frequency is higher, and the sound will be louder.

Abstract

The invention relates to the technical field of fire-fighting equipment and discloses a fire-fighting spray header with an alarm function. The fire-fighting spray header comprises a base and a sealingplug, an air inlet channel communicating the inside and the outside is formed in the base, the air inlet channel inclines from top to bottom, an air vibration channel is formed in one side of the base and used for communicating an inner cavity of the air inlet channel with an external environment, and the sealing plug blocks a lower end opening of the air inlet channel. The air inlet channel andthe air vibration channel are formed in one side of the base. When the spray header is used, since the flow velocity of water in the base is high, known from the Bernoulli principle, the pressure intensity in the base is small, external air enters the base along with the air inlet channel, when the external air passes through an inlet of the air vibration channel, the air is shunted to generate vibration and make a sound, and meanwhile, the air inlet channel easily vibrates to make a sound when the external air accelerates to enter due to a small aperture, so that the base generates harsh sound during water spraying to achieve an alarm effect.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting sprinkler head with an alarm function. Background technique [0002] The fire sprinkler is used in the fire sprinkler system. When a fire breaks out, the water is sprayed out through the splash plate of the sprinkler to extinguish the fire. At present, it is divided into a pendant sprinkler, a vertical sprinkler, a common sprinkler, and a side wall type. Sprinklers etc. refer to figure 1 As shown, it includes a base 1, a choke column 2, a splash plate 3, a glass tube 4, a mounting seat 5 and a sealing plug 6. When a fire breaks out, the liquid in the glass tube 4 expands, and the glass tube 4 is broken. The mounting base 5 falls under the impact of the water due to the loss of supporting force, and the water in the base 1 is directly sprayed onto the splash plate 3 in an umbrella shape to the peripheral side. [0003] The fire sprinkler head is ...
