Description

Automatic locking device for gas intermediate valve

The present invention relates to an automatic locking device for a gas intermediate valve. More specifically, the gas safety intermediate valve is equipped with an analog type timer and a measuring gauge for checking the remaining amount of gas in the tank. The present invention relates to an automatic locking device for a gas intermediate valve that can be automatically locked after the completion of food cooking or when the intermediate valve is locked to solve anxiety caused by a fire risk.

In general, an intermediate valve installed in the middle of a gas tank and a gas range in which city gas or propane is stored has a rotary knob connected to a ball valve installed inside the valve body so that the user can prepare food or similar food. For the purpose of use, press the intermediate valve and rotate it at the same time so that the gas stored in the city gas or gas tank is supplied to the gas range, and after the cooking is completed, rotate the intermediate valve in the reverse direction to block the supplied gas. It was to be able to maintain.

However, since the supply and shut-off of the gas is only dependent on the intermediate valve, when the food is being cooked in the gas range when the food leaves the gas range, the gas fire is incinerated and the gas leaks as well as the surroundings. As the gas is scattered in the air, there is a risk of explosion when it is ignited again, and it may cause damage to property and lives due to the risk of fire or suffocation when going to the outside without checking the presence of the intermediate valve or during bedtime. There was a great issue.

In addition, when using a gas tank with propane stored, the cooking user cannot check the remaining amount of gas remaining in the tank, and if the gas is exhausted during food cooking, the cooking has to be stopped before replacing it, and it is used as a heating fuel. If there was a problem that the heating efficiency is lowered in winter.

In other words, the residual amount of gas can be confirmed through the meter of the gas storage tank installed outdoors, and it was difficult to check whether the gas is supplied normally. Therefore, in order to solve this inconvenience, the indoor alarm connected to the outdoor meter. It has also been proposed to lay out.

However, these additional alarm devices also do not satisfactorily provide the desired functions due to frequent failures along with the difficulty of connecting the gas tanks installed indoors and the indoor alarms. The problem of inevitable work was on the rise.

The present invention is to solve the above problems, the object of the present invention, the user can easily check the gas residual amount on one side of the intermediate valve equipped with a measuring gauge, the intermediate valve can also automatically lock the selected time Equipped with a timer so that you can easily check the remaining gas in the gas tank to prevent the disruption of food cooking, while preventing the risk of fire even if you go out or go to bed with the intermediate valve open, you are anxious about the gas It is to provide an automatic locking device of the gas intermediate valve that can eliminate the problem.

The intermediate valve 10 and the measuring gauge 11 are inserted into the opening 13a of the bracket 13 in which the remaining amount indicator hole 12 is engraved in the longitudinal direction on the upper surface thereof, and the time is applied to the outer peripheral surface of the bracket 13. The normal timer case 14 with the scale engraved is attached integrally.

In addition, a shaft 16 press-fitted to the timer 15 is inserted into the through hole 14a formed at the center of the timer case 14, and the handle 16 allows the user to select a cooking time of the food. 17 is fitted, and the shaft 16 is wound with a spring (not shown) for providing a driving force to the timer 15.

In addition, at one end of the shaft 16 press-fitted to the timer 15, a circular first cam 19 protruding from the bottom surface of the shaft 16 is rotatably fitted at a predetermined angle. (19) Below the second cam 20 having a moving section hop 20a formed on the outer circumferential surface is caulking at one end on the shaft 16, and the stopper 21 is provided at the bottom of the timer case 14. The protruding auxiliary bracket 22 is coupled by a fastening member such as a screw 23.

In addition, the auxiliary bracket 22 is fitted to the stopper rail 25 of the frame 24 for attaching the timer 15 into which the intermediate valve 10 is inserted to the wall surface by a fixing member.

On the other hand, the ball valve (10b) and the timer (15) inserted into the intermediate valve 10 is equipped with a locking means for supplying or blocking gas to the gas range according to the selected cooking time, the locking means is a timer case ( 14 and the rotatable piece 30 rotatably mounted to the auxiliary bracket 21 and the protruding piece so as to contact the outer circumferential surfaces of the first and second cams 19 and 20 to stop the time of the timer 15. It consists of a first link 32 formed with (31).

In addition, a compression spring 39 connected to the auxiliary bracket 22 is connected to the lever 35 coupled to the first link 32.

Referring to the effect of the automatic locking device of the gas intermediate valve according to the present invention configured as described above with reference to (a), (b) of FIG.

After the measurement gauge 11 is mounted on the gas input side of the intermediate valve 10 into which the ball valve 10b is inserted, such a measurement gauge 11 appears through the remaining amount display hole 12 formed in the timer case 14. The timer 15 and the auxiliary bracket 22 are fixed to the stopper rail 25 formed in the frame 24 by fixing the timer 15 and the auxiliary bracket 22 with the screw 23 while being inserted into the opening 13a of the bracket 13 so as to be fixed to the wall surface or the like. . At this time, at one end of the shaft 16 press-fitted to the timer 15, the locking protrusion 18 protruding from the first cam 19 is positioned in the moving section groove 20a of the second cam 20. The valve 10 and the timer 15 are assembled by locking means.

In this way, when the user wants to cook food or the like in the assembled state, first, by turning the knob 17 fitted to the shaft 16 of the timer 15 clockwise to match the cooking time, the timer case 14 When placed at a suitable time for food cooking engraved in the), the spring spring mounted on the shaft 16 is relaxed and the first cam 19 mounted at one end of the shaft 16 rotates as shown in (a) of FIG. At the same time, the locking projection 18 of the first cam 19 is moved in the moving section groove 20a of the second cam 20 to move the second cam 20 to the stop position at the time indicated by the timer case 14. As it is rotated, the protruding pieces 31 formed in the first link 32, which are the locking means caught in the engaging grooves 19a and 20b formed in the first and second cams 19 and 20, respectively, are first and second cams. (32) (38) are moved along the outer circumferential surface.

At this time, the lever 35 coupled by the first link 32 and the hinge 36 is moved to the left while the compression spring 39 is tensioned, and at the same time, the second link 38 fixed with the nut 37. Rotate the counterclockwise direction to open the ball valve inserted into the intermediate valve 10 to supply gas for cooking time, and when cooking for a long time over 1 hour, rotate the handle 17 counterclockwise to the timer case 14 You can put it at the position of 0 engraved on it.

When the cooking time of the protruding pieces 31 in contact with the outer circumferential surfaces of the first and second cams 19 and 20 is completed, the first and second cams 19 (as shown in FIG. As the protruding piece 31 is caught in the engaging grooves 19a and 20b formed in the 20, and the compression spring 39 is restored to its initial state, as the lever 35 is moved to the right direction, the second link ( 38) is rotated clockwise to cut off the supply of gas to prevent food overflow and accidents placed on the gas range in advance to maintain a safe state.

As described above, according to the present invention, the automatic locking device for the gas intermediate valve is equipped with a gas residual amount gauge on one side of the intermediate valve for supplying gas and a timer for automatically locking the intermediate valve at a time selected by the user. Easily check the amount of gas remaining in the gas tank where the front plate is stored to prevent troubles when cooking, and prevent the risk of fire when going out or going to bed with the intermediate valve open. I can eliminate it.
