Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a plug-in type gas tank that is attached to the end of a gas supply conduit.

[Prior Art and Its Disadvantages] As shown in FIG. 4, the conventional gas kettle uses a handle 03 to open and close the closure 02 inside the kettle body 01, so opening and closing the handle 03 is troublesome.

If the handle 03 is stopped midway, a halfway open state will occur.

Connection mechanism part 04 between handle 03 and closure 02
There is a risk of gas leaking through the

Further, dust, detergent, water, etc. may enter the connecting mechanism portion 04, causing trouble.

The outer shape of the kotuku becomes large, and the production cost becomes high.

There were other drawbacks.

Also, as a solution to these drawbacks, the fifth
As shown in the figure, there is a disk-shaped rotary valve 012 in the gas tank 01, a rotary member 09 with a spiral groove 011 for rotating the rotary valve 012, and a drive member 08 for driving the rotary member 09. is installed in the gas passage of the gas tank main body 01 and the socket 06 is attached to the plug, the rotary valve 0
12 rotates to open the gas hole in the partition wall 013,
There is a proposal for a so-called one-touch type gas tank which is configured to close the gas hole when the socket 06 is removed.

However, in the case of this known gas kettle, since the mechanism uses a spiral to open and close the rotary valve 012, there are many parts and the frictional resistance of the movable parts is large, making it difficult to operate and making the gas kettle large in size. There is a drawback.

[Purpose of the present invention] The present invention is proposed in view of the above points.
The purpose of this invention is to propose a one-touch type gas tank that has a small number of parts, has low frictional resistance of moving parts, and can be made smaller in size.

[Structure and operation of the present invention] The structure of the one-touch type gas tank proposed as a means for achieving the above object is as follows.

Behind the gas outlet with a valve seat formed at the center of the plug, a horizontal gas passage is formed inside the gas tank body, and within this horizontal gas passage there is a safety valve that can be brought into close contact with the valve seat, and a safety valve that penetrates in the direction of the horizontal gas passage. A slide valve having a through hole formed therein and a gas inlet communicating with the through hole is installed, and a coil spring is installed between the safety valve and the slide valve and between the slide valve and the gas tank main body, and a gas pipe is connected to the gas tank main body. The opening is formed on the gas inflow side of the slide valve, a partition wall is provided between the gas pipe connection port and the slide valve, and an opening communicating with the gas inflow port of the slide valve is provided in the partition wall. One-touch type gas tank.

In the above-mentioned gas tank, when an outlet is attached to the plug, the safety valve is first pushed in and the valve seat is opened, and at the same time the slide valve slides toward the back so that the gas inlet fits into the opening. As a result, the gas at the gas pipe connection port enters the through hole from the opening through the gas inlet of the slide valve, enters the socket from this through hole via the valve seat, and flows from the gas pipe to the gas appliance. . When the socket is removed from the plug, the safety valve returns to close the valve seat, and the slide valve slides back to close the opening.

[Embodiment and its operation] Fig. 1 shows an embodiment of the gas tank according to the present invention, in which 1 is the gas tank main body, 2 is a plug, and 3 is a gas outlet provided at the center of the plug 2. A valve seat 4 is formed within the valve seat 3 .

Reference numeral 5 denotes a horizontal gas passage extending toward the back of the gas tank main body 1 following the gas outlet 3, and within this horizontal gas passage 5 is a slide valve 6 that can be slid freely.
is included.

As shown in FIG. 2, the slide valve 6 is formed by rolling an elastic metal plate, has a slit 7 in the upper longitudinal direction, and has a guide pin 9 protruding from the gas tank main body 1 inside the slit 7. The engagement is designed to prevent the slide valve 6 from rotating. The slide valve 6 has the property of expanding its diameter due to its elastic action, and by utilizing this property, it always comes into close contact with the inner wall surface of the gas passage 5 to ensure sealing performance.

8 is the side of the slide valve 6 (the lower part in the example)
This gas inlet 8 is a through hole 10 that is opened through a pipe through the inside of the slide valve 6.
is connected to.

Reference numeral 11 designates a spring holding cylinder fixed in the gas passage 5, and inside this holding cylinder 11 is a coil spring 1 that pushes out the safety valve 15 that is in close contact with the valve seat 4.
2 is retained. Reference numeral 13 is a guide cylinder that is partially inserted into the slide valve 6 and slides together with the slide valve 6, thereby allowing the slide valve 6 to slide stably. 14 is a coil spring that pushes the slide valve 6 forward together with the guide cylinder 13.

Reference numeral 16 denotes a gas pipe connection port of the gas tank main body 1, and the gas pipe connection port 16 is located perpendicularly to the gas passage 5. Reference numeral 17 denotes a partition wall provided between the gas inlet 8 of the slide valve 6 and the gas pipe connection port 15, and the partition wall 17 is provided with an opening 18 through which gas flows. 18 is a position facing the gas inlet 8 of the slide valve 6 during use.

Next, the operation of the above embodiment will be explained.

When the gas socket is opened (Fig. 3) When the socket 19 is attached to the plug 2, the push rod 20 inside the socket 19 pushes the safety valve 15 to open the valve seat 4, and when the safety valve 15 is pushed in, the slide valve 6 moves backward. The gas inlet 8 matches the opening 18. As a result, the gas in the gas pipe connection port 16 flows from the opening 18 to the gas inlet 8, the through hole 10, the valve seat 4,
The gas flows into the socket 19 through the gas outlet 3 of the plug 2, and then to the gas appliance via a gas pipe (not shown).

When the gas socket is closed (Fig. 1) When the socket 18 is removed from the plug 2, the safety valve 15 is pushed out by the coil spring 12 and tightly contacts the valve seat 4, closing this valve seat 4. When the safety valve 15 is pushed out, The slide valve 6 is also pushed out by the coil spring 14, and the gas inlet 8 is removed from the opening 18.

As a result, the gas inlet 8 and the opening 18 are closed and the flow of gas is stopped.

[Effects of the present invention] As described above, the present invention provides a slide valve at the back of the safety valve, and slides this slide valve together with the safety valve to open or shut off the gas flowing in the gas passage. Therefore, all opening and closing operations are performed only by the axial force that is applied when the socket is installed or removed.

As a result, there is no need to open and close the closure using a handle as in the past, and there is no need to convert axial motion into rotational motion, so there is little frictional loss of force and opening and closing operations are performed extremely smoothly. effective.

In addition, since the slide valve has a through-hole inside and a gas inlet leading to the through-hole on the side, it is possible to make a slide valve by rolling a metal elastic plate, for example, and it is easy to manufacture. The cost is low;
It is possible to reduce the weight, and because of its simple structure, it can also be made smaller, and there is no fear of failure.
