Abstract

PURPOSE:To improve safety for gas leakage due to breaks or the like of a diaphragm by providing a controller to shift the valve opening timing at the time of fire extinguishment of a proportional valve with a closing function, having a gas sealing portion using the diaphragm provided with an electromagnetic valve provided at a gas inlet side of a gas burning apparatus and the diaphragm provided in series. CONSTITUTION:The titled system is provided with the proportional valve 3 with a closing function, having the electromagnetic valve 2 at the side of the gas inlet 1 and the sealing portion using the diaphragm 11 provided in series, gas being supplied to the nozzle 5 of a burner 4. A controller 10 is provided in a gas combustion controller 6, and at the time of extinguishing a combustion apparatus, a signal to close the proportional valve 3 with the closing function is produced after the electromagnetic value 2 is actuated. For this reason, when the proportional valve 3 is closed, the gas pressure is certainly decreased, and hence no pressure is applied to the diaphram 11. Accordingly, even when the proportional valve with the closing function, having the sealing portion of the disphragm is used, deterioration caused by the stress of the diaphragm is reduced and the safety is improved.

Gas control valves installed in the gas passages of gas-burning equipment that change over time are comprised of a solenoid valve that opens and closes the gas passage according to signals from an electric controller, and a proportional valve that varies the gas pressure to the burner nozzle. be done. In this case, in order to maintain the airtightness of the valve and increase reliability, two solenoid valves are connected in series, or a dual solenoid valve is used in which two solenoid valves are integrally molded. For this reason, a gas control valve consisting of two electromagnetic valves and a proportional valve has the drawback of being large and expensive. Therefore, a proportional valve with a closing function has been considered, which is a proportional valve equipped with a closing function, and one electromagnetic valve and one proportional valve with a closing function constitute a gas control valve for a combustion device.

１４とプランジャ１５で構成されている。FIG. 1 shows the configuration of this kind of conventional gas combustion equipment. A proportional valve 3 with a closing function having a sealing portion by a diaphragm is provided in series with the solenoid valve 2 provided on the gas-filled side, and supplies gas to the nozzle/115 of the burner 4. 6 is a gas combustion control device that controls the solenoid valve 2 and the proportional valve 3 with a closing function. FIG. 2 shows a configuration diagram of a proportional valve with a closing function having a sealing portion using a diaphragm. A valve seat 9, which is an elastic member, is provided between the gas man lower and the gas outlet 8, and a valve body 10 is provided facing the valve seat 9, and M! J, fi2-1
II'' body 10 and is composed of a diaphragm 11 that applies a force in the closing direction due to gas pressure, a spring 12 that applies a closing force to the valve body 10, and an electromagnetic Electricity that generates force
It is composed of a coil/L'13 which is a force generating section, a yoke 14 which is a magnetic material, and a plunger 15.

り着火しバーナ４で燃焼を開始する。In this configuration, when the combustion equipment is ignited, the electromagnetic valve 1-2 is opened by a signal from the gas combustion control device 6, and the proportional valve 3 on the closing function side is also opened and held so that a predetermined gas pressure is reached. The fuel is supplied to the fuel tank lv5, ignited by an igniter (not shown), and combustion started by the burner 4.

The force produces a secondary pressure proportional to the force exerted on the spring 12 by the governor principle.

When the combustion equipment is extinguished, a signal from the gas combustion control device 6 causes the solenoid valve 2 and the proportional valve 3 with a closing function to close, thereby maintaining the airtightness of the valves.

The valve closes while gas pressure remains applied to the valve. For this reason, even when the combustion equipment is not in use, the diaphragm 11 becomes a block where stress due to pressure is applied, which is not preferable for the diaphragm 11 as a seal part. it is,
Generally, nitrile rubber is often used for the diaphragm 11, but it can crack or even break if it is subjected to stress due to ozone in the atmosphere. A. Fram 1

The purpose is to improve the durability of the diaphragm and improve safety against gas leaks due to rupture of the diaphragm.

In order to shift the timing, a controller is provided which generates a signal to close the proportional valve on the closing function side after operating the electromagnetic valve.

Figure 3 shows the configuration of a heating combustion device used indoors, in which a solenoid valve 2 is provided on the gas port 1 side, and a closing function is provided with a sealing portion by a diaphragm 11 in series.

In the above configuration, when a combustion device is used, the operations during ignition and combustion are the same as conventional ones, so the explanation will be omitted. However, when extinguishing a combustion device, as shown in the operation timing chart in Figure 4, the controller 10 first operates the solenoid valve 2 to cut off the gas supply, and after a set delay time has elapsed. , closes the proportional valve 3 with the closing function.Unfortunately, when the proportional valve 3 closes with the closing function, no pressure is applied to the diaphragm 11 because the gas pressure has definitely decreased. For this reason, when combustion equipment is not in use, stress is rarely applied to the diaphragm, so
Deterioration caused by stress, such as cracks caused by ozone, etc., is not accelerated, and safety is improved.

Since there is no residual gas pressure and no stress is applied to the diaphragm, deterioration will not be accelerated. This has the effect of reducing deterioration and improving safety.
