Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the fire extinguishing check valve comprises a valve body 1, a valve plate 2, a fire protection device 3 and a fire extinguishing device 4.

Wherein, a valve plate 2 is arranged in the valve body 1, and the opening and closing of the channel in the valve body 1 are controlled by the rotation of the valve plate 2. Meanwhile, the fire protection device 3 is further arranged in the valve body 1, when fire breaks out, the fire protection device 3 senses that the ambient temperature rises, the valve plate 2 is locked, the channel in the valve body 1 is closed, and the fire is prevented from spreading.

The fire extinguishing device 4 is arranged above the valve body 1 and is used for extinguishing a fire source.

The valve body 1 and the fire extinguishing device 4 can also be connected through a connecting plate 5; in particular to a fire extinguishing device 4 which is arranged in a hole of the fire extinguishing device 4 on a connecting plate 5; the valve body 1 is arranged in the valve body 1 assembling hole on the connecting plate 5.

A sealing ring is arranged between the valve body 1 and the connecting plate 5, so that the connection tightness of the valve body and the connecting plate is improved. A sealing ring is also arranged between the fire extinguishing device 4 and the connecting plate 5.

The fire extinguishing device 4 comprises a containing cavity 43 arranged above the valve body 1, a fire extinguishing agent 42 is arranged in the containing cavity 43, and a fusing valve 41 is arranged on the containing cavity 43.

The accommodating chamber 43 includes an accommodating chamber body 431 in which the fire extinguishing agent 42 is placed and a connection pipe 432 for conveying the fire extinguishing agent 42; in order to facilitate regular inspection of the fire extinguishing agent 42 in the accommodating chamber 43, the expired fire extinguishing agent 42 can be replaced in time, and therefore the accommodating chamber body 431 is arranged outside the flue 6; one end of the connection pipe 432 is connected to the accommodation chamber body 431, and the other end is disposed in the flue 6, wherein the fusing valve 41 is disposed at one end of the connection pipe 432 disposed in the flue 6 to control the connection pipe 432 to open and close.
