Electromagnetic valve block structure for detecting gas pipeline

The present invention is applied to a technical field having a structure for detecting a gas valve group for a gas pipeline, in particular, a method capable of forcibly starting a solenoid valve for a predetermined time before each ignition of a fire to supply a gas gas flow into a full line. After the base and its pipeline are inside, the power supply required for the excitation of the solenoid valve is forcibly cut off, and the pressure value inside the base and its pipeline is maintained to be consistent through a certain period of time to determine whether the ignition furnace is maintained. When there is a large leak or a small leak inside the pedestal or its pipeline before the fire, the gas supply source flowing into the pedestal can be completely and effectively cut off, and the carbon monoxide poisoning phenomenon and the prevention of leakage while using the side can be prevented. The accidental danger of gas explosion occurred.

According to the conventional gas leak detection device, please refer to the approved invention patent certificate No. I285248, which mainly includes an excitation device and a reed switch on one side of the body, and an induction device and a pressure detector on the other side. And the excitation device and the pressure detector are connected to the control circuit board to feed back the signal or transmit the signal, wherein the main body has an inlet connected to the inner valve chamber, and a passage extends in the valve chamber. The channel is connected to the outlet and is connected to the detection chamber, and a sealing cover is arranged in the valve chamber and the detection outside, and the cover is controlled to generate adsorption. The magnetic force is disposed in the valve chamber of the body and is connected to the control circuit board. The magnetic spring opening relationship is disposed above the excitation device and the channel, and is a normally closed channel, and the outlet can be controlled by the excitation device. The opening and closing, the pressure sensing device is controlled by the influence of the gas entering the passage in the body, and the upper and lower deformations are floated. The bottom of the inner side surface is provided with a control point. When the pressure sensing device is deformed and floated up and down, the control point is high. The position also varies.
