Embodiment 1

[0024] Embodiment 1, the intelligent blocking device for flammable gas tempering.

[0025] like figure 1 As shown, the flammable gas tempering intelligent blocking device of this embodiment includes a accommodating cavity enclosed by the device shell 5, and the accommodating cavity is divided into a sensing cabin 1, a blocking cabin 2 and a monitoring cabin 3 by a partition 4, and the blocking The cabin 2 is provided with an explosion-proof solenoid valve 7, the input end of the explosion-proof solenoid valve 7 is connected to the gas cylinder through the intake pipe 6, and the output end of the explosion-proof solenoid valve 7 is connected to the input end of the tempering blocker 9 through the hose 8, and the tempering The blocker 9 is embedded on the partition 4 between the sensing chamber 1 and the blocking chamber 2. The output end of the tempering blocker 9 is connected to one end of the metal pipe 10, and the other end of the metal pipe 10 is connected through the exhau...

Embodiment 2

[0041] Embodiment 2, an intelligent blocking method for flammable gas tempering.

[0042] A method for intelligently blocking flammable gas tempering in this embodiment is applied to the intelligent blocking device for flammable gas tempering in Embodiment 1, and specifically includes the following steps:

[0043] Infrared thermometer, temperature control switch and combustible gas concentration detection device are used to detect whether the tempering phenomenon occurs. When the tempering phenomenon occurs, the explosion-proof solenoid valve is controlled to close to prevent the input of combustible gas.

[0044] The method for intelligently blocking the tempering of combustible gas in this embodiment is applied to the intelligent blocking device for tempering of combustible gas described in Embodiment 1, which can effectively detect the phenomenon of tempering, and prevent the tempering from being damaged when tempering occurs. The spread of gas cylinders can avoid unnecessa...

Abstract

The invention discloses a combustible gas backfire intelligent blocking device and method.The combustible gas backfire intelligent blocking device comprises a sensing cabin, a blocking cabin and a monitoring cabin, an anti-explosion electromagnetic valve is arranged in the blocking cabin, and a controller is arranged in the monitoring cabin; and the controller is electrically connected with an infrared thermometer arranged in the sensing cabin, a temperature control switch and a combustible gas concentration detection device arranged in the blocking cabin. The intelligent combustible gas backfire blocking device is connected between the gas supply hose and the combustible gas cylinder in series, the backfire condition of combustible gas is automatically sensed through three detection devices with different principles, namely the infrared thermometer, the temperature control switch and the combustible gas concentration detection device; and when the combustible gas is subjected to tempering, the tempering blocker can be used for postponing and blocking the further spreading of the tempering and controlling the explosion-proof electromagnetic valve to close the valve so as to prevent the gas from being input.

Description

technical field [0001] The invention relates to the field of tempering blocking, in particular to a combustible gas tempering intelligent blocking device and method. Background technique [0002] Gas cutting and gas welding technology is widely used for cutting or welding metal materials in substations. Due to the complex use environment and the different skill levels of field operators, fire accidents caused by "tempering" combustion of acetylene gas cylinders are not uncommon. At the same time, because the gas cylinder is filled with high-pressure gas, once the gas leaks and ignites, the flame will be sprayed out in a jet shape. It is difficult for conventional fire extinguishers to extinguish the fire of the pressure gas cylinder. Because some employees lack the emergency response ability of acetylene tempering, they often can only passively wait for the inside of the cylinder to fire. The gas burns out, and the acetylene pressure cylinder has the risk of explosion, which...
