Description

[Detailed description of the invention] (Field of industrial application) This invention uses two push buttons to open and close the two parent and child gas passages to the parent and child burners, and perform a series of operations from ignition to adjusting the firepower and extinguishing the fire. This invention relates to a gas valve for parent and child burners operated by a linear lever.

(Prior Art and Problems) As shown in FIG. 10, the conventional parent-child burner gas valve has a main burner pot 51 and a child burner pot 52 that are separately provided, and each of them is connected to one parent-child burner 5.
3 and 54, respectively, and buttons 5 for ignition and extinguishment.
5, 56, 57, 58 with two linear levers
It was common to operate at 9.60. Therefore, since the two gas tanks are operated separately, the operation is troublesome, and there are disadvantages in terms of cost due to the large number of structural parts, and there are problems in that it is easy to operate erroneously.

(Technical Problem) Therefore, in the present invention, the cock part is made into one so that one gas valve can be provided with push buttons for ignition and extinguishing, and linear levers for parent and child. This is a technical issue.

(Means for solving the problem) In order to solve the above technical problem, the present invention
A single valve case body 5 having a gas inlet 1, a pilot gas outlet 2 and two gas outlets 3, 4 to the master and minor burners is provided with two push buttons 6, 7 for ignition and extinguishment. , has two linear levers 8, 9 for the parent and child, and has a mechanism that opens the main valve 10, safety valve 11, and pilot valve 12 by operating the ignition push button 6, and operates the igniter at the same time; When the valve stem is pushed by operating the linear lever 8, the second passage opens so that the gas from the safety valve communicates with the main passage.
main valve 14, a lock mechanism that holds and locks the main valve 10 and safety valve 11 in the pressed position when the ignition push button 6 is pressed so that the main valve 10 and safety valve 11 are opened and the pilot valve 12 is closed, and and a lock release mechanism for releasing the lock,
parent and child needle control valves 15 for individually restricting gas flow paths to the parent and child gas outlets 3 and 4 by operating respective linear levers for the parent and child; 16.

(Function) When the ignition push button 6 is pressed, the stem 6a of the push button 6 connects the first valve rod 27 and the push rod 2 of the safety valve 11.
8 are pushed in sequence, and the main valve 10, pilot valve 12, and safety valve 11 are pushed open. Therefore, part of the gas flows from the gas inlet 1 through the main valve 10 to the pilot gas outlet 2, and the rest flows from the safety valve 11 to the chamber 17, and from there passes through the branch passages 18 and 19 to the master and slave burners. The gas flows out to the two gas outlets 3 and 4 of. At the same time, the igniter 13 is activated to first ignite the pilot and then the sub burner. At this time, if the main burner linear lever 8 is between a low flame and a high flame, the flame transfers to the main burner and ignites it.

When the pressure on the ignition push button 6 is released, the lock lever 20 engages with the engaging portion 6b of the push button stem 6a to prevent the push button 6 from returning completely and the locked state is maintained. Therefore, the ignition push button 6 is locked at the pushed-in position after returning a short distance, so the main valve 10 is opened, the pilot valve 12 is closed, and the safety valve 11 is opened.

Next, when the linear levers 8 and 9 are operated in this state, the needle control valves 15 and 16 are moved forward and backward by the linkage between the pins 21 and 22 and the elongated holes 23 and 24, thereby limiting the amount of gas.

Now, if you operate the parent linear lever 8 to position a in Figure 2, the needle rod 15a will move in direction A in Figure 3, and the passage will be at its maximum, resulting in a strong flame, while in position b, it will be reversed. The flames are low because they move in the direction of the arrow and are confined to a narrow area. Moreover, when the valve stem 14a of the second main valve 14 faces the pressure release part 26 of the linear lever 8 when it moves to the position c, the valve spring 14b causes the second main valve 14 to
Since the main valve 14 is closed, gas outflow from the parent gas outlet 3 is stopped. Next, when the secondary linear lever 9 is operated to position d in Fig. 2, the needle rod 16a moves in the direction C shown in Fig. 3, and the passage is maximized, making it strong.On the other hand, when it is moved to position e, Becomes weak.

When extinguishing a fire, press the fire extinguishing push button 7. Then, the lever piece 7a of the button 7 moves the lock lever 20 slightly backward (in the direction of arrow H) against the bias of the spring 25, as shown in FIG. When the lock is removed, the lock is released.

Accordingly, the ignition push button 6 returns completely, and the first valve stem 27 is accordingly pushed back by the force of the spring 29, so the main valve 10 closes and everything stops.

(effect) The present invention has the following unique effects.

The gas cock part for the parent and child burners is a single unit that is common to the parent and child, and it is equipped with two push buttons for ignition and extinguishing, and two linear levers for the parent and child to adjust the firepower for each parent and child from ignition. ,
and perform a series of operations leading to extinguishing the fire.

Therefore, the operation is simple, there is no erroneous operation, and safety is improved.

Furthermore, the number of parts is reduced, which is advantageous in terms of cost.

For the master burner, a needle control valve adjusts the range from strong to weak by operating the linear lever, and a closing function is added at the closed position by the action of the second main valve, and these are controlled by the operation of a single master linear lever. It can be done only by

When the ignition push button is pressed, the lock mechanism is automatically activated, and the open state is reliably maintained until the extinguishing push button is pressed next, which prevents unexpected situations such as misfires. It can be implemented with a simple configuration by engaging levers without adding any special structure.

(Example) Two linear levers 8 and 9 for parent and child are linear case 5a that constitutes the upper part of valve case main body 5.
are pivoted on pivots 31 and 32, respectively, and are provided so as to swing from side to side about these as fulcrums.
It is regulated by inserting 5 and 36.

A recess is formed in the parent linear lever 8 by cutting and raising on the flat surface, and this is inserted into the valve stem 1 of the second main valve 14.
This is a release part 26 for 4a. This release part 26
Only when the linear lever 8 reaches the closed position c, the valve stem end 14a' comes into sliding contact with the lower surface of the plate and faces the release portion 26, whereby the pressure is released.

Therefore, the linear lever 8 is moved from the closed position c to b, a.
When the second main valve 14 is moved in the direction of , the second main valve 14 is opened because it is instantly pushed from the cam surface 26a to the lower surface of the plate.

The second main valve 14 has a lower chamber 17 and an upper chamber 17a.
The lower chamber 17 communicates with the passage to the child needle control valve 16 through a branch passage 19, and the upper chamber 17a communicates with the master needle control valve 15 through a branch passage 18. There is.

The locking mechanism is operated by a spring 25 as shown in Figures 8-9.
The energized lock lever 20 is attached to the holder 29 so that it can move forward and backward, and the rear end 20a is attached to the engagement piece 6b of the stem 6a of the ignition button 6 by spring pressure.
When it comes into contact with and is pushed in, it engages with the engaging portion 6c and prevents it from floating. Also, this lock lever 20 has a projection piece 2.
0b is provided and the lever piece 7a of the fire extinguishing button 7 is attached to this.
When the button 7 is pressed down, the projecting piece 20b is pushed in the direction of the arrow H by the action of the cam.

The needle control valves 15 and 16 are provided with needle rods 15a and 16a so as to move forward and backward in the passage, and when moving backward (arrows A and C), the valve opening widens, and when moving forward (arrows B and D), the valve opening becomes narrower. It is designed to limit the flow of gas.

The igniter (not shown) is linked to the ignition push button 6 and simultaneously operates an ignition switch and the like when pressed.

The safety valve 11 is a thermoelectric type that uses a thermocouple, and when it is opened by being pushed with a push rod 28, it is heated to a certain temperature by the ignition of the pilot, and even if the pressure from the push rod is released, it will not open due to thermoelectromotive force (magnetic force). This is to maintain the valve open state. Therefore, when the thermal electromotive force disappears due to a misfire or the like, the valve is automatically closed by the bias of the valve spring 11a.
