Abstract

PURPOSE:To enable to perform high or low combustion by means of entirely different systems, by a method wherein, a device, such as a gas space heater, which is adapted to burn a combustion amount through control of it, is constituted such that a part of the parts for a gas flow rate controller can be simply replaced. CONSTITUTION:An electromagnetic valve which opens and closes a part of a gas flow passage is provided in the rear of a gas governor which controls a governor valve 3 with the aid of a diaphragm 1 and a spring 2. An electromagnetic valve part drives a plunger 5 with the aid of an electromagnetic coil 4, and controls operation of a valve seat 7 part located in the gas flow passage through vertical movement of a valve 6 at the forward end of a plunger 5. Meanwhile, in the rear of a gas flow passage 8 on the secondary side of a governor, a bypass 9 is located in parallel to a gas passage having the valve seat 7 of the electromagnetic valve, and a passage 10 on the secondary side of the electromagnetic valve and the outlet side of the bypass passage 9 are intercommunicated through a gas joining chamber 11 part. A sealing part 12 is located in the gas joining chamber 11 part, and through utilization of the sealing part 12, sealing packings 13 and 17, being different from each other, are attached, and this forms a single gas passage 14 and two independent gas passages 14 and 18. This enables both control of combustion of the single burner and control of combustion through ON and OFF of either of the two burners.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention can be used as a gas flow rate control configuration for controlling the amount of combustion in equipment such as gas heaters that burn the amount of combustion in a manner that increases or decreases the amount of combustion.

Configuration of conventional example and its problems As a conventional example, when switching the combustion amount to high or low, there is generally a case where one burner is switched to two stages Hi-Low to burn, and a case where combustion is performed by switching one burner to two stages Hi-Low. 9 There are two ways to burn with 0N-OFF on one side, and each has a different gas block for gas flow control, and there are many aspects that lack mutual compatibility. , There was no gas block that could be used in common when one side of the (-) was controlled ON-OFF and controlled in two stages of strength and weakness.

Purpose of the Invention In order to solve the above-mentioned problems, the present invention provides a pump flow rate control device that has one passage and one pump by easily replacing some parts of the pump flow rate control device. It was invented for the purpose of making it possible to control Hi-Low, and at the same time completely separate it into two passages, and also to make them common so that the output on one side can be controlled in ON-OFF.

Structure of the Invention In order to achieve the above object, the gas flow rate control device of the present invention has the following features:
A bypass passage independent of the solenoid valve passage is connected in parallel with the solenoid valve passage for flow rate adjustment provided at the rear of the gas power banner, and at the same time, an OUT of the bypass passage is connected at the rear of the solenoid valve secondary side. The sides merge, the merge part,
At the same time, the solenoid valve 2 that has once merged can be connected to one gas passage, and the convergence part can be separated and independent using a separate part, so that it can be installed from the outside. The next side passage and the bypass secondary side passage are completely separated, and it is configured so that it can be switched when there are two different passages.

DESCRIPTION OF THE EMBODIMENTS As shown in the configuration diagram of FIG. 1, in the block that controls the gas flow rate, a solenoid valve that opens and closes a part of the gas passage is installed behind the gas governor that controls the governor valve 3 using a diaphragm 1 and a spring 2. establish.

In the electromagnetic valve section, a plunger 5 is driven by an electromagnetic valve coil 4, and a valve 6 at the tip of the plunger 6 is moved up and down, thereby opening and closing a valve seat 7 provided in the gas passage. On the other hand, behind the governor secondary side gas passage 8, a bypass passage 9 is provided in parallel with the gas passage having the valve seat 7 of the solenoid valve, and the solenoid valve secondary side passage 1° and the out side of the bypass passage 9 are as follows. They are communicated through 11 portions of the waste merging chamber. The gas merging chamber 11 is provided with a sealing part 12, and by using this sealing part 12 and installing different seal packings, it is possible to configure one gas passage or two independent waste passages. It is now configurable.

First, a case where one burner performs Hi-Low combustion will be explained. In this case, the sole part 12 of the gas merging chamber 11 is used to attach the seal A13 (not shown in Figure 2), and as shown in Figure 3, the seal lid A1 having the first gas outlet 14 is attached.
Close the lid at step 5.

At this time, before attaching the seal lid A15, use the threaded part provided in the bypass passage 9 section. As shown in FIG. 7, an orifice 16 for regulating the bypass flow rate is incorporated. By freely changing the hole diameter of the orifice 16, the bypass flow fL can be arbitrarily varied. As shown in FIGS. 6 and 7 above, the seal packing A13. A configuration diagram is shown in which a sealing lid 16 is attached and one burner is used to perform strong and weak combustion.

FIG. 6 shows the strong twist firing in this case, and FIG. 7 shows the weak combustion. Therefore, depending on the opening/closing state of the solenoid valve 6,
The gas flow rate from the first gas outlet 14 can be switched in two stages. In this case, the flow when strong is the first gas outlet 14
It is determined by the nozzle diameter of the burner that will be installed later. In general, if the design is made based on the following relationships: passage diameter of the solenoid valve secondary passage 1o > burner nozzle diameter > hole diameter of the orifice 16,
A single burner can be burned in two stages, strong and weak, using a gas passage configuration.

Next, a case where one side of the two burners is turned ON-OFF to switch the intensity of combustion will be explained.

In this case, by using the seal part 12 of the gas merging chamber 11, a gasket B17 having two independent passages is installed in the apparatus, as shown in FIG.
4 and the seal lid B19 with the second gas outflow [118]
Close the lid.

Therefore, in this case, as shown in FIGS. 8 and 9,
In the gas merging chamber 11, two independent gas passages are formed by seal packing B1γ, and the first gas outlet 14 communicates with the bypass passage 9, and the second gas outlet 1 communicates with the bypass passage 9.
8 independently communicates with the solenoid valve secondary side passage 10 behind the valve 6 of the solenoid valve.

Therefore, with two burners, one side is turned on and off.
The configuration of the waste passage when the strength is switched by F is as shown in FIGS. 8 and 9 as described above, and in this case, the passage on the second gas outlet 18 side is opened and closed. The combustion on the burner side detected at the tip is 0N-OFFI.
, the burner side connected to the first gas outlet 14 side is always
It will end up burning.

As mentioned above, by using the 11 gas merging chambers and simply replacing parts, it is possible to burn one burner strongly or weakly, or by turning one side of two burners OFF. I can do it.

Effects of the Invention As described above, according to the present invention, by simply replacing some of the component parts, it has become possible to perform combustion with completely different intensity switching.
