A side surface of the electromagnetic valve 3 is provided with a threaded part 11 having a tapered hole in the center, into which the pipe 9 is inserted via a nut 10 and a sleeve 12. When the pipe 9 is inserted into the tapered hole and tightened to the screw 11 by turning the nut 10, the tip of the sleeve 12 is deformed by the tightening force of the nut 10, tightening the outside of the pipe 9, and connecting the tapered hole of the solenoid valve 3 and the pipe 9. is sealed. Similarly, taper holes are made on both sides of the parts other than the solenoid valve, and the parts are connected to the pipes using sleeves and nuts.

どうしても装置自身大きくなつてしまう。 The flammable gas entering from the inlet pipe 2 passes through various parts such as solenoid valves and pressure regulators and pipes, and reaches the connection joint after adjusting the flow rate and pressure. It is necessary that there be no gas leakage from connected parts. Many methods of connecting parts using metal pipes, sleeves, and nuts are commonly used, and making these parts made of stainless steel has advantages such as good durability, but the pipe itself It is hard and inflexible, making it difficult to work with. Furthermore, it is difficult to tighten the nuts properly; if they are loose, they may come off due to vibration, causing gas leakage from the joint between the pipe and the component. Also, if the nut is tightened too much, cracks may develop in the outer wall of the nut, which may allow gas to leak. Additionally, this device requires many pipes, nuts, and sleeves, and requires a lot of work time. Furthermore, a space is required inside the device for a tool to tighten the nuts.
The device itself inevitably becomes larger.

る。 Since the gas control section of this device uses propane gas as the combustion gas, there is a risk of explosion if the gas leaks, so safety is the most important point. Also, changes in gas flow rate and air flow rate are
It is necessary to always supply a stable flow rate of air and propane gas to the burner, as this directly affects the reproducibility of the apparatus. Furthermore, the gas control section of this device also requires operation from outside the device. That is, the fourth
In the figure, in order to adjust the pressure of air or propane gas, the center knob 39 of the pressure regulator 20 is turned while looking at the display needle of the pressure meter 21, and the size of the frame above the burner is adjusted using the knob 40 inside the needle valve 30. Adjustments are made, and the manual valve 31 is also opened and closed by the knob 41 from outside the device. It is also important in handling the device that it is easy to adjust the pressure, flow rate, etc. by entering from the outside of the device.

ングにて外部洩れを防いでいる。 Next, details of the gas control section will be explained. In FIGS. 4 and 5, each part of the gas control unit is installed on one side of the plate 38, and the upper part includes the auxiliary gas inlet 19, pressure regulator 20, pressure meter 21, and pressure switch 22 as air components. , connection joint 2
3, and the combustion gas inlet 28, solenoid valve 29, and pressure regulator 2 are installed as propane gas side parts on the lower stage.
0, pressure meter 21, needle valve 30, manual valve 3
1. A connection joint 23 is provided. All these parts are fixed on the plate by screws 42. Air from the compressor enters the pressure regulator 20 through the auxiliary combustion gas inlet 19, where the original pressure of approximately 2 kg/cm 2 is regulated to approximately 1 kg/cm 2 , and the pressure meter 2
1. Joint 2 connected via pressure switch 22
3 leads to the burner. On the other hand, propane gas enters the pressure regulator 20 via the combustion gas inlet and the solenoid valve 29. Here, propane gas with an original pressure of approximately 1Kg/ cm2 is
The pressure is regulated to 0.2~0.5Kg/ cm2 , and the needle valve 3
The gas flow rate is adjusted at 0, and the gas is guided to the burner through the manual valve 31 and the connecting joint 23.If the pressure in the compressor decreases for some reason, such as a malfunction in this device or damage to the connection pipe, the pressure switch 22 operates, driving the electrical system and closing the solenoid valve 29, cutting off the propane gas flow path.
This prevents the measurement conditions from changing due to frame changes. In addition, gas leakage can be confirmed by closing the solenoid valve 29 and the manual valve 31 with propane gas injected into the gas control unit, and confirming that the needle of the pressure meter 21 does not change in this state. . Further, even if the solenoid valve 29 fails on the propane flow path side, if the manual valve 31 is closed, gas leakage accidents due to failure of the solenoid valve can be prevented. In other words, the manual valve serves as a safety device to check the parts placed in the propane gas flow path and in case the solenoid valve malfunctions. The auxiliary gas inlet 19 and the combustion gas inlet/connection joint 23 are parts for connection with a compressor, a propane cylinder, and a burner.
The parts constituting the above gas control section are plate 3.
The plate 38 is mounted on the flat surface of the plate 38 with screws 42, and holes made inside the plate 38 serve as passages to connect the respective parts. In Figures 6 and 7,
The plate 38 has a large number of holes on the component mounting position surface, on both sides of the plate, and on the bottom surface of the plate.
These holes serve as passages between the parts on the plate, connecting each part well. That is, in FIG. 7, compressor air enters the hole in the plate from the auxiliary gas inlet 19 and is led to the pressure regulator 20.
The air that has passed through the pressure regulator 20 passes further through the passage of holes in the plate 38 to the connecting joint. Since the pressure regulator 20, pressure meter 21, and pressure switch 22 are connected through holes in the plate, they can be operated satisfactorily as a gas control section. The contact portion between the component on the plate 38 and the plate has a stepped portion on the component side into which an O-ring 43 is inserted, and the O-ring prevents external leakage.

ふさいでいる。 In FIG. 6, the arrangement of the parts and the hole positions in the plate are designed so that the holes inside the plate and the holes 45 for mounting each part do not come into contact with each other. Further, holes made from both sides and the bottom of the plate 38 are closed by press-fitting balls 44 coated with adhesive.

た。 The parts on the plate are fixed with screws, so they are easy to replace if they break down, but for parts with a low failure rate such as pressure switches and pressure meters, apply adhesive to the holes on the plate. There is also a method of press-fitting and eliminating the O-ring. In the gas control unit of the present invention, each part is mounted on the plate in a concentrated manner, making the whole compact and easy to assemble.Furthermore, if the plate is made of aluminum, machining is easy and the thick side of the plate does not have to be machined. It can be used in Also, since there is no metal piping like in the past,
We were able to obtain gas control that is resistant to vibrations and external shocks and allows for stable flow and pressure control.

から簡単にできる。 In addition, with this device, it is necessary to adjust the pressure by turning the knob of the pressure regulator while watching the pressure meter, and to close the manual pot when the device finishes measuring. If the device is assembled as is with the plate of the gas control unit of the present invention lying on its side, the pressure regulator knob and manual knob will be deep inside the device, making it difficult to operate. This problem was solved by placing the gas control plate vertically on the side or in front of the flame photometer. As shown in Figure 3, install the gas control unit vertically with the parts mounting side facing the side wall of the flame photometer. If a window is attached to each position of the manual knob, the pressure meter's display needle can be observed through the window, and the knobs and knobs can be easily operated from outside the flame photometer.

易にできる。 Further, the auxiliary gas inlet 19 and the combustion gas inlet 28 of the gas control unit 16 need to be connected to a compressor or a cylinder, but only the auxiliary gas inlet 19 and the combustion gas inlet 28 need to be connected to the outside of the device as shown in FIG. If you do so, you can easily connect the compressor and cylinder.
