Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas flow rate control device that adjusts the amount of gas supplied to a gas burner from a large flow rate to a small flow rate equivalent to a "toro-ka". This is the purpose.

Conventionally, gas flow rate control has been done using a gas kottok with a closing valve or a governor. With a gas kottok, it is difficult to operate when adjusting the firepower to a small value, and the flame goes out, and the adjustment is difficult depending on the type of gas. The disadvantages are that there is no universality, and the governor is subject to many variations due to environmental changes, requires pressure adjustment work, and is difficult to miniaturize as a device.

The present invention overcomes these drawbacks.
FIG. 1 is a circuit diagram showing an embodiment of the present invention.
A flow control device 2 is installed in the gas passage opening/closing device 1.
, and further connect the nozzle 3 and combustion burner 4 to the outside of the appliance wall 5.
is operated using knobs 6 and 7. Kotoku 1 is either fully opened, and Kotoku 1 is not narrowed down.

FIG. 2 shows changes in flow rate, with the horizontal axis representing the operating angle and the vertical axis representing the flow rate.

In FIGS. 3 and 4, 8 is a gas inlet, 9 is a gas outlet, and 10 is an outer frame of the main body, and vice versa. Reference numeral 11 is a thick flat plate with a circular controller disk that divides the circumference into equal parts, each having a plurality of disks (four disks are shown in this example) depending on the type of gas.
has a passage hole 12, and further rotates it,
An operating rod 20 is provided at the center of the disk so that a plurality of passage holes for a specific gas can be selected, and a convex portion 14 is provided so that after selection, the rod can be positioned in a recess 13 provided on the outer frame of the main body. There is. 15 is a thick flat circular fixed disk, which can be used for one of the gas types.
It has a gas passage hole 15a with an area that includes a set of a plurality of passage holes, and is fixed to the outer frame of the main body. This fixed disk 15 is flush with the controller disk 11 to eliminate flow leakage. Reference numeral 16 denotes a circular and flat operating disk having a thickness and an opening 16a such as a V-shaped notch, which is flush with the controller disk 11 and has all of a set of a plurality of passage holes 12 and the opening. 16a, a hollow operating rod 21 is provided at the center of the disk so as to rotate and slide on the plane of the controller disk 11 to open and close the passage hole.
has been established. This operating disk 16 connects the hollow operating rod 21 to the operating rod 2 of the controller disk 11.
0 and can be operated from the outside. O-rings 17 and 18 are installed to prevent gas leakage. The pressure of the seal by the surface of each disk is the spring 1
9 allows the load to be adjusted freely.

Based on this configuration, several holes are created in stages from the hole with a large flow rate to the optimum hole with a small flow rate equivalent to "Toro-fire" in the multiple passage holes for each gas type. By selecting the passage hole 12, the hole can be opened or closed, thereby making it possible to accurately control the flow rate.

It has universality by selecting the gas type, and can be operated from outside to facilitate adjustment work in service. During the ignition operation of the cockpit 1, the hole in the controller disk 11 is made to have the largest diameter to prevent ignition failure. That is, the operating disk 16 is configured to move to the position where the flow rate is maximum in conjunction with the operation of closing the pot 1.

As is clear from the description of the above embodiments, the following effects can be obtained according to the present invention.

(1) The combination of the main body outer frame, a flat fixed disk, a flat controller disk with multiple passability, a flat actuating disk that opens and closes the passage hole, and a seal presser spring is more effective than conventional control devices. It has a compact configuration.

(2) In a controller disk having multiple passage holes, multiple passage holes are provided depending on the gas type, and the flow rate of each gas can be adjusted by selecting multiple passage holes for a specific set of gas types. It allows for variation and universality.

(3) In a controller disk with multiple passage holes, the flow rate can be adjusted from the gas flow rate equivalent to a "toro-hi" to the large flow rate of conventional gas consumption by changing the diameter of the passage holes in stages. You can smoothly control the temperature up to "fatty fire".
