るものである。Generally, when adjusting the gas flow rate in a gas appliance, the area of the gas flow hole in the stopper is changed from fully open to fully closed by turning the stopper of the cock. However, since LPG has a high unit gas calorific value, it is very difficult to adjust the heat to a small flame rather than a large flame on a gas stove, for example. The present invention provides a device that adjusts the gas combustion amount more easily and linearly than the general 6B and 6G gas types even in high unit gas calorific values.
ガス器具はガスコックを開閉し、ガスコックの下流に位

ス流量孔を閉にする回転角度との差が小さくなり、大変
むずかしく日常よく経験していることである。A gas appliance opens and closes a gas cock, and a nozzle located downstream of the gas cock spouts a combustion amount of gas that is less than a specified gas flow rate. The gas flow holes of the closure for adjusting the gas flow rate have a diameter of, for example, about 4 mm, the nozzle diameter is about 1 mm, and the area ratio of the gas flow holes of the closure and the nozzle is id16:1. Therefore, reducing the area of the gas flow hole in the closure means that the difference between the rotation angle and the angle at which the gas flow hole is closed becomes smaller, which is very difficult and something we often experience on a daily basis.
本発明はガス流量を調節するのに普通に閉子を回転する
動作でリニヤにガス流量を調節するもので以下その実施
例について説明する。The present invention linearly adjusts the gas flow rate by rotating the closure normally, and an embodiment thereof will be described below.

There is. 14 is a receiving part of the rod spring 13.The rod end part 9-1 of the gas flow rate adjusting rod 9 is in contact with the nozzle hole 15, and the rod movable arm 17 of the rod head 16 on the rear side on the opposite side is inserted and is tightened with a nut 18. Extraction has been stopped. The rod movable arm 17 passes through an arm hole 20 of a mounting plate 19 that connects the cock body 1, and extends by an arm operating piece 21 that operates the rod movable arm 17. The arm actuating piece 21 is inserted into the cock shaft 23 together with the piezoelectric actuating piece 22.

Reference numeral 31 is a knob for pushing and turning the cock shaft 23 to operate it. When the shutter 2 is in the closed state, the rotor head surface 33 of the rotor 32 is pressed against the rotor rotation stopper hole 34 of the mounting plate 190 by a spring 035 so that the cock shaft 23 does not rotate simply by turning the knob 31. has been done.

２より離れる。Next, the invention will be explained in detail. When the cock shaft 23 pushes the rotor 32 and rotates it to the left while pushing the size 31 one by one, the rotor head surface 33 comes out of the rotor rotation stopper hole 34, and the cock shaft 23 rotates 11 to the left. When the cock shaft 23 is pushed, the tip of the cock shaft 23 pushes the ignition valve 37 and the QIJ ring B39 separates from the closure 2.

When the above-mentioned ignition valve 37 is not pressed, a part of the raw gas flows from the gas flow hole B4 around the ignition valve 3 through the gas flow hole D42 to the ignition outlet hole 43, and flows into the ignition burner (not shown). )go to. Also, by rotating the cock shaft 23 to the left, the arm operating piece 21 and the piezoelectric piece 22 rotate to the left. Nozzle hole 15 in rod phrase screw 10
As the gas moves away from the gas, a specified amount of raw gas is ejected. On the other hand, the pressure-type actuating piece 22 presses the hammer 29 by rotating counterclockwise, compressing the hammer spring 30, and when it comes off the hammer 29, the hammer 29 hits a piezoelectric element (not shown) in the piezoelectric generator 28 to generate a high voltage. It generates an ignition source spark. After the above process, when the finger of the push-and-turn operation is released from the twister 3, the cock shaft 23 returns from the closing member 2 side to the mounting plate 19 side due to the return pressure of the spring B25, and the ignition valve 37 returns to its original position. return. The rotor head surface 33 is not the rotor rotation stopper hole 34 but the phrase plate 1.
9, and the cock shaft 23 is located on the rotor stopper hole 3.
4, it can freely rotate clockwise until it enters the rotor head surface 33.

合たけガス流量は調節され大火から小火へと変化する。If you want to adjust the gas flow rate now, turn the knob 31 to the right. The rotation of the cock shaft 23 will rotate the arm operating piece 21, and the gas flow rate adjustment rod 9 will approach the nozzle hole 15. From tl in Fig. 3A to t2 in Fig. 3B, a gap is formed, and when tl>t2, the flow rate of the combined gas is adjusted and changes from a large fire to a small fire.
ｔ１〜ｔ２への変化はガス流量調節ロンド９０回転角度

調節することができる。The change from t1 to t2 is related to the rotation angle of the gas flow rate adjusting rod 90 and the pitch of the rod mounting screw 10, but can be adjusted linearly.

However, as shown in the embodiments, the present invention is a gas flow rate adjustment system that has the feature of being able to easily make fine adjustments linearly from full open to small fire without changing the operation of a general gas cock, and in which each part is integrated. It is a device.
