れた通常の燃焼状態となる。(Function) To explain the operation using the illustrated one, when the push operation member 10 is moved forward from the starting position to the terminal position, the igniter 9 is pushed and activated, and
Not only the electromagnetic safety valve 4 as the main valve 4 is pushed open by this, but also the gas on-off valve 5 is pushed by this and opens greatly backward, and the auxiliary on-off valve 19 opens backward in conjunction with this. 4 and 5, the side channel 18 parallel to the flow control valve 6 is opened and gas is conducted through it, and the gas burner is thereby increased in gas volume.
Stable ignition and combustion can be obtained in the burner. Next, when the pressing operation member 10 is released from the pressure to the intermediate position, the gas on-off valve 5 returns to the predetermined opening position and the auxiliary on-off valve 19 is closed. This state is, for example, as shown in FIG. Thus, the increase in the amount of gas via the side passage 18 is lost, and the burner enters a normal combustion state in which a predetermined amount of gas controlled by the flow control valve 6 is introduced.

に順次導かれるようにした。 In the drawings, reference numeral 10 denotes a push-button type pressing operation member on the front surface of the instrument body 1, and reference numeral 11 denotes a locking member that temporarily locks the member 10 in an intermediate position during its return operation.
Reference numeral 12 designates a separate lever-type operating member on the upper side, which is normally located in the initial position shown in FIGS. 1 and 2, and when pressed, springs back to the right in the drawings. The above-mentioned igniter 9 is moved forward to the final position where it should be activated against the pressure, and then when the pressure is released, the locking member 11 is moved back to the intermediate position mentioned above to the left in the drawing. When the locking member 11 is once locked and then the locking member 11 is released, it is returned to the left in the drawing to its original starting position.
The electromagnetic safety valve 4 and the gas on-off valve 5 described above are operated in response to the control rods 22 and 23 as follows. That is, the electromagnetic safety valve 4
When the member 10 moves forward, it is pushed by the member 10 and opens once, and is then maintained in the open position by the electromotive force of a thermocouple (not shown), and the gas on-off valve 5 is moved forward. According to the movement, in the drawing, the valve passes beyond a predetermined valve opening position to the rear position, and then, according to the return movement to the intermediate position, it is sequentially guided to the left in the drawing to the valve opening position. I made it.
更に前記した操作部材12は根部の軸12aを

上下動を許容されるようにした。 Further, the aforementioned operating member 12 is prepared so as to be able to freely tilt left and right about the shaft 12a at the base, and according to the tilting, the aforementioned flow rate control valve 6 is operated as follows in response to this tilting. I made it. That is, the flow control valve 6 has a pin 1 extending forward from its top.
3, the pin groove 14 has an open upper part on the member 12 side.
At the same time, the intermediate portion of the pin 13 is inserted into the diagonally vertical cam groove 16 formed in the guide cylinder 15 on the outer periphery of the valve 6, and thus the member 12
According to the tilting movement, the opening is adjusted by moving up and down guided by the cam groove 16. The guide tube 15 is constructed by bending a springy metal plate into a U-shape, and is fixed onto the block 2 with a screw 17 at one end, so that the entire guide tube 15 is allowed to move up and down to some extent. It was to so.
尚、前記方向に開放したピン溝14を構成する
ことによつてガス種変更時(流量調節弁交換時)
にレバ12を取外すことなく案内筒15を取外す
ことが出来る。 By configuring the pin groove 14 that opens in the above direction, it is possible to change the gas type (when replacing the flow rate control valve).
The guide tube 15 can be removed without removing the lever 12.
更に第3図に鎖線で示すごとくカム溝16の一
方を側縁に連通させれば、流量調節弁6の挿入後
ピン13をカム溝16に簡単に挿入出来る。 Furthermore, if one side of the cam groove 16 is communicated with the side edge as shown by the chain line in FIG. 3, the pin 13 can be easily inserted into the cam groove 16 after the flow rate regulating valve 6 has been inserted.
尚、流量制御弁6を更に詳述すれば、流量制御
弁6は、中心に最小流量を確保する小孔6aを有

れて、これが上下動するとき、該外径部6bと弁
座6cとの間隙が調節されて流量を加減されるよ
うにして成る。 In addition, to explain the flow rate control valve 6 in more detail, the flow rate control valve 6 has a small hole 6a in the center to ensure the minimum flow rate, and has several outer diameters with different diameters on the circumference of the flow rate control valve 6. When the valve is guided by the cam groove 16 and moves up and down, the gap between the outer diameter part 6b and the valve seat 6c is adjusted to adjust the flow rate.
尚、該流量制御弁6が最も下動したとき外径部
6bが弁座6cに当つて小孔6aからのみの最小
流量となるが、このとき該流量制御弁6は前記案
内筒15によつて上方に持上げられる力が働くた
め、弁座6cに強く外径部6bが当つて弁座6c
又は外径部6bが傷められることを妨げる。 When the flow rate control valve 6 moves down the most, the outer diameter portion 6b hits the valve seat 6c and the minimum flow is only from the small hole 6a. Since a force is applied to lift the valve seat 6c upward, the outer diameter portion 6b strongly hits the valve seat 6c.
Alternatively, the outer diameter portion 6b is prevented from being damaged.
本発明はかゝるものに於いて特に該ガス通路3

た。 The present invention particularly relates to the gas passage 3 in such a case.
A side passage 18 is formed in parallel with the control valve 6, and the side passage 18 is connected to the gas on-off valve 5 so that the valve 5 opens at the rear position described above but closes at the opening position described above. An on-off valve 19 is provided.

比較的小型に得られるようにした。 To explain this in detail with reference to the illustrated one, the on-off valve 5 accommodates a valve body 5c facing a valve hole 5b on the front in a valve chamber 5a extending in the front-rear direction so as to be able to freely move backward against a spring 5d. The auxiliary on-off valve 19 is of a type in which a valve body 19b that extends rearward continuously and integrally with the valve body 5c is housed in a rear valve chamber 19a that communicates with the valve chamber 5a. In this case, the valve chamber 19a is provided with a step 19c in the middle to form a large diameter portion that expands at the rear, and the side passage 1
8 forms a communication passage 18a extending laterally in the rear part of the valve chamber 19a, and thus the valves 5, 19 are provided in two consecutive stages, front and rear, making the overall structure relatively compact. I made it possible to do so.

御弁6が弱絞りの状態にあるときの吹き消えを解
消させた。 Incidentally, the side passage 18 with the auxiliary on-off valve 19 interposed
is formed by drilling a hole from the back side of the valve blot, and the communicating passage 18a is formed through the side passage 18. The gas on-off valve 5 and the auxiliary on-off valve 19 are assembled from the end of the side passage 18, and a blind cover 20 is provided at the end to prevent this. Further, the amount of gas flowing through the side passage 18 is set to be less than the maximum flow rate set in the flow rate control valve 6, thereby eliminating blow-out particularly when the flow rate control valve 6 is in a weak throttle state.

The pilot gas valve 8 intervenes in the pilot gas passage 7. In this case, it is convenient because the pilot gas valve 18 and the auxiliary on-off valve 19 can be processed at the same time.
The valve closes at the starting position shown in the figure, and if the pressing operation continues to the final position, the valve opens as shown in Figure 5. If the valve subsequently returns to the intermediate position, the valve closes again as shown in Figure 6. Operate.

の作業を簡単に行なうことが出来る。 Further, in the above-mentioned embodiment, the flow rate control valve 6 is directly controlled by the swinging of the operating member 12, but this may be performed via the auxiliary operating member 20 as shown in FIG. When doing so, the upper surface of the guide tube 15 is not covered by the operating member 12, and operations such as removing the screw 17 that fixes the guide tube 15 and replacing the flow rate control valve 6 according to the gas type can be easily performed. can be done.

図に示す実施例と特に変るところはない。 FIG. 12 shows still another embodiment, in which the main valve 4 is replaced with the electromagnetic safety valve and is of a cutoff valve type, and the flow rate control valve 6 is attached to the tip of the columnar valve body 6d with a small diameter. A protrusion 6e is formed, and the protrusion 6e is inserted into the valve hole 6f having two stages with different diameters to form a narrow protrusion 6e.
A minimum flow rate is ensured by the gap l1 between the narrow part of the valve hole 6f, and a gap larger than the gap l1 is ensured between the stepped part of the valve hole 6f and the tip of the valve body 6d. I made it. Other configurations are shown in Figures 1 to 7.
There is no particular difference from the embodiment shown in the figures.

This shows the main part of an embodiment in which the auxiliary on-off valve 19 and the auxiliary on-off valve 19 are provided separately. When the on-off valve 5 opens and is subsequently pressed to the terminal position, the auxiliary on-off valve 19 opens the gas on-off valve 5.
By pushing open through and releasing the pressure at the end position,
When the gas on-off valve 5 returns to the intermediate on-off position, the auxiliary on-off valve 19 is closed again.

The side passage parallel to the control valve is opened and closed by an auxiliary on-off valve, which has the advantage of not having the above-mentioned disadvantages of the conventional control valve in which the control valve itself is switched at one end to the increasing side. Because it has a two-axis configuration in which the main valve is placed on the rear axis of the valve and the main valve is provided on the side of these valves, the valve seats of the main valve and the on-off valve can be machined at the same time, making processing easier. There is an effect.
