Bar, causes the keying of gate valve difficult；Contradicted between traditional gate valve usually through spring, realize the sealing between valve plate and valve seat,
Abrasion occurs in valve plate after long-time use, changes for the gradient between valve plate and sealing surface, influences to seal
Effect, and spring is used for a long time, the elastic force of spring can be eliminated with the passage of time, it may appear that between valve plate and valve seat
Leakproofness it is unstable；And fire-fighting sluice valve needs to transmit the information of the keying of gate valve to fire fighter, it is therefore desirable to accurately
Information is transmitted to fire fighter.
Therefore, it is necessary to a kind of fire-fighting sluice valve that can solve above-mentioned technical problem.
The content of the invention
Be not in get rusty phenomenon, essence the object of the present invention is to provide a kind of simple in structure, easy to operate, long-term be not used
The high Novel firefighting gate valve of accurate transmission message, production efficiency.
The technical scheme is that：A kind of Novel firefighting gate valve, including valve body, the valve rod that is arranged in valve body, it is described
Fluid passage is equipped with valve body, the bottom both sides of the valve rod are equipped with air bag, cavity, the top of the valve rod are equipped with the valve rod
Portion is equipped with inflating port, and the upper end of the inflating port is equipped with the sealing-plug coordinated with it, and what is communicated on the valve rod with air bag is equipped with
Gas outlet, the gas outlet are connected with air bag, are equipped with partition plate in the cavity, resetting spring is connected on the partition plate, described
Cavity is divided into first chamber and the second chamber connected with inflating port, the gas outlet and the first gas port and the second gas port by partition plate
Connection, first gas port, the second gas port are communicated with second chamber, and the both sides that the fluid passage is in contact with air bag are equipped with
Sensor, the fluid passage side opposite with air bag are equipped with microswitch, and the top of the valve rod is equipped with control device,
The control device is equipped with alarm.
Further, the inner wall of the partition plate is equipped with sealing strip, and the sealing strip coordinates with cavity, bulkhead seal.
Further, it is detachable between the valve body and valve rod.
Further, the sensor, microswitch, control device and alarm are connected by electric wire.
The present invention has the advantages and positive effects of：Due to the adoption of the above technical scheme, by inflation/deflation by air bag
Gas charge and discharge, when avoiding the gas in air bag from leaking, and being contacted after airbag aeration with the microswitch on fluid passage,
By the closure of sensor passes signal prompt gate valve, use is very convenient, the problem of being not in gate valve internal rust, gate valve
Leakproofness stablize, there is simple in structure, easy to maintenance, the advantages that processing cost is low, production efficiency is high.

Embodiment
Elaborate below in conjunction with the accompanying drawings to the present invention.
As shown in Figure 1 and Figure 2, a kind of Novel firefighting gate valve of the present invention, including valve body 1, the valve rod 2 that is arranged in valve body 1,
Fluid passage 3 is equipped with the valve body 1, the bottom both sides of the valve rod 2 are equipped with air bag 4, cavity 5, institute are equipped with the valve rod 2
The top for stating valve rod 2 is equipped with inflating port 6, and the upper end of the inflating port 6 is equipped with the sealing-plug 7 coordinated with it, on the valve rod 2 with
What air bag 4 communicated is equipped with gas outlet 8, and the gas outlet 8 is connected with air bag 4, and partition plate 9, the partition plate are equipped with the cavity 5
Resetting spring 10 is connected on 9, cavity 5 is divided the second chamber 12 connected for first chamber 11 and with inflating port 6 by the partition plate 9,
The gas outlet 8 is connected with the first gas port 13 and the second gas port 14, and first gas port 13, the second gas port 14 are and second chamber
12 communicate, and the both sides that the fluid passage 3 is in contact with air bag 4 are equipped with sensor 15, and the fluid passage 3 is opposite with air bag 4
Side be equipped with microswitch 16, the top of the valve rod 2 is equipped with control device 17, and the control device 17 is equipped with alarm
Device 18.
