Description

Burner Valve with Safety Device {SAFETY VALVE FOR BURNER}

The present invention relates to a valve for a burner, and more particularly to a burner valve with a safety device that can prevent the handle from being operated left / right when the valve is locked.

Typically, a domestic gas stove or a burner for a business is attached to a valve for regulating and opening and closing the amount of gas. That is, the valve body is composed of a nozzle connected to the burner to supply gas, and a handle for controlling the amount of gas discharged through the nozzle and opening and closing the valve. On the other hand, the valve has a handle that protrudes to the outside while the handle is moved due to external impact or carelessness of the user to open the valve, which is not only a large explosion accident due to outflow of gas without the burner is ignited But it will cause enormous casualties. Accordingly, the burner valve is provided with a safety device so that the handle is not opened by a malfunction.

As the safety device, the handle is not rotated unless an additional device mounted to the handle is accompanied by an operation of pushing down or pulling or pushing an additional lever mounted on the handle.

As a conventional technique of such a structure, Korean Laid-Open Utility Model Publication No. 1999-4264 (valve with a locking lever) has been proposed. However, the above conventional technology is complicated in structure and the manufacturing cost is increased, and the upper and lower double mounted lever is pressed with the thumb and index finger so that the stopper provided at the lower lever can be rotated in a state where it is disengaged from the hanging groove. It becomes inconvenient to use.

The present invention is to overcome the above-mentioned conventional problems, to provide a burner valve having a simple structure can reduce the manufacturing cost and is easy to use safety device.

In order to achieve the above object, the present invention has a nozzle and a hose connector connected to the burner and the handle 10 is assembled on the body 20 provided with a rotating shaft 24 on the upper side, and the handle has a hole to one side. Is formed is coupled to the rotating shaft 24 by the bolt and the end of the engaging piece 12 is bent downward, the bracket 40 is formed with side plates on both sides under the handle, the lower side on one side As the fixing washer 26 having the recessed groove is fixed, the engaging piece of the handle is fitted into the recessed groove, and the leaf spring 30 is supported between the handle and the bracket.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 to 4 show the configuration of the burner valve with a safety device according to a preferred embodiment of the present invention

According to the drawing, there is a nozzle 22 and a hose connector 23 connected to the burner and a body 20 having a rotating shaft 24 at the top thereof, and a handle having a locking piece 12 at the end thereof with the rotating shaft 10. ) Is assembled, and the bracket 40 and the fixing washer 26 having the side plates 42 formed on both sides under the handle are assembled, and the leaf spring 30 is assembled to be hard between the handle and the bracket.

The above is described in more detail as follows.

In the rear is formed a hose connector 23 is connected to the gas supply hose, in the front of the rotating shaft for opening and closing the inside of the body 20 to the top of the body 20 is provided with a nozzle 22 is coupled to the burner (24) protrudes upward. And the one side is bent over the body 20 is in close contact with the side of the body fixed washer 26 is assembled so that the other side is formed with a concave groove 28 cut in the '' 'shape. A bracket 40 having a hole 44 in the center of the fixing washer 26 is assembled to the rotating shaft. The bracket 40 has side plates 42 formed on both sides thereof, and a stopper 46 is formed on one side thereof and stops the rotation of the rotary shaft 24 while contacting the rear surface of the fixed washer. Thereafter, a handle 10 having an assembly 11 on one side above the bracket 40 is mounted by the bolt 18 above. That is, the assembly 11 is a hole 14 is formed in the center is fitted to the rotating shaft, the front end is formed with a locking piece 12 bent downward, which is a recess groove formed in the lower washer 26 Fitted with (28). And the rear of the assembly 11 has a spring fixing portion 16 is bent while being cut in the lower portion. Then, the leaf spring 30 is inserted between the handle 10 and the bracket 40 to elastically push the handle. The leaf spring 30 is bent in the center to have an elastic force to the outside, the lower portion is placed on the upper surface of the bracket 40 and the upper portion is coupled to the upper handle 10. At this time, the protruding piece 34 is formed in the upper end surface of the leaf spring 30 is coupled to the spring fixing portion 16 provided on the handle. And the bent portion of the leaf spring 30, that is, the concave groove 32 is formed in the front while the rotation shaft 24 is inserted therein. On the other hand, the rotating shaft 24 has a flat portion formed on both sides and the hole 44 of the bracket to be fitted therein, the recess groove 32 of the leaf spring, the hole 14 of the handle is formed in a rectangular shape as the handle When the 10 is rotated, the leaf spring 30 and the bracket 40 and the rotating shaft 24 is rotated at the same time.

Referring to the operation of the subject innovation is configured as follows.

First, as shown in FIG. 3, when the handle 10 is positioned vertically in the body 20, the valve is locked and the handle 10 is pushed up by the lower leaf spring 30 to maintain the raised state. On the other hand, the end of the locking piece 12 is lowered down into the recessed groove 28 of the fixing washer 26 is fixed. Therefore, the handle is fixed without being rotated left and right. Then, in order to open and close the valve, pressing the handle first, as shown in FIG. 4, the locking piece 12 opposite to the handle is lifted up and is separated from the recessed groove 28 of the fixing washer 26. When the handle is rotated, the valve is opened while the leaf spring, the bracket, and the rotating shaft 24 rotate together with the handle.

As described above, the burner valve with a safety device according to the present invention can have a relatively simple structure and reduce manufacturing costs, and when the handle is pressed, the valve can be opened while the locking device is released. This is simple and safety is further increased.
