Detailed Description

Example (b):

as shown in fig. 1, the present embodiment provides a fire extinguishing and explosion preventing device with gas blocking function, which includes a tee 1, where the tee 1 includes a first port 1a communicated with a gas inlet pipe, a second port 1b communicated with a gas appliance, and a third port 1c communicated with a fire extinguisher, the first port 1a is provided with a first joint 3, the second port 1b is provided with a second joint 5, and the third port 1c is provided with a third joint 4. The second joint 5 and the third joint 4 adopt a pagoda external thread external tooth joint. The second connector 5 is connected with the gas appliance through a hose, and a pipe hoop or a pipe clamp is used for fastening the connection. The third joint 4 is connected with a fire extinguisher hose, and a pipe hoop or a pipe clamp is used for fastening the connection. After the device is installed, the third connector 4 and the fire extinguisher are always in a connected state, and when a fire occurs, the fire extinguisher can be directly opened according to an operation guide of the fire extinguisher.

In this embodiment, the first connector 3 and the third connector 4 are in direct communication.

In this embodiment, the movable non-return head 2 is arranged in the pipeline where the first joint 3 and the third joint 4 are located.

In this embodiment, the side of the non-return head 2 close to the third joint 4 is a concave surface 2a, and the side close to the first joint 3 is a convex surface 2 b.

The convex surface is of a hemispherical structure; the concave structure 3a is a concave structure which can be tightly attached to the hemispherical structure.

The concave surface is arranged to receive the pressure to the maximum extent so that the non-return head moves, this end being directed towards the joint 4 in the direction of the fire extinguishing agent inlet.

In this embodiment, one side of the first joint 3 near the backstop is provided with a concave structure 3a adapted to the convex surface of the backstop. The concave structure is matched with the convex surface of the check head, after the fire extinguisher is connected to the third connector 4, the fire extinguisher pushes the check head 2 to one side of the first connector 3, and the concave structure is matched with the convex surface of the check head to be tightly attached, so that the first connector 3 can be more effectively plugged.

In this embodiment, the diameter of the non-return head 2 is adapted to the inner diameter of the pipeline where the first joint 3 and the third joint 4 are located.

The working principle of the device is that the check head 2 is pushed to the direction of the first joint 3 of the gas inlet by the pressure of the fire extinguisher, the gas is blocked from entering, meanwhile, the fire extinguishing agent enters the gas pipeline of the gas appliance to realize fire extinguishing, and the pipeline negative pressure is prevented from being generated, so that the further explosion is prevented.

Referring to fig. 2, in a normal working state, gas enters the tee joint from the joint 1 and enters the gas appliance from the third joint 4, the check head 2 is located at the third joint 4, the gas flows normally, and the gas appliance can work normally. The position of the backstop in the normal working state of the device is shown in figure 2 and is positioned at one side of the third joint 4.

Fig. 3 shows the fire extinguishing working state. When a fire disaster occurs at the position of the gas appliance, the fire extinguisher is started according to the operating regulation of the fire extinguisher, at the moment, the fire extinguishing agent is flushed into the tee joint from the third connector 4, the check head 2 is quickly flushed to the first connector 3 by pressure under the pressure and is tightly attached to the concave surface of the connector 3, the gas is blocked from entering the tee pipeline, meanwhile, the fire extinguishing agent enters the gas appliance quickly through the connector 5, the flame is directly blocked from burning from the inside of the flame, meanwhile, the gas is also prevented from being blocked to form pipeline negative pressure, and the explosion is prevented. The position of the backstop in the fire extinguishing working state of the device is shown in figure 3.

The utility model provides a thinking and method of gas block fire extinguishing explosion-proof equipment, the method and the way that specifically realize this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary technical personnel in this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improve and moist decorations should also regard as the utility model discloses a protection scope. All the components not specified in the present embodiment can be realized by the prior art.
