Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cartridge tank in which a cap with a valve is attached to a tank and the tray is mounted on the tray by inversion.

[Prior Art] In a cartridge tank, a cap with a valve is removed, liquid such as kerosene is supplied, the cap is strongly tightened to move the cartridge tank, and the cartridge tank is turned over to open the valve to supply the liquid.

At this time, if the cap is not tightly tightened, the cap will come off when the tank falls, and the liquid in the tank will flow out all at once. A cartridge tank is used as the oil tank of the oil combustor, and if the above trouble occurs when the cartridge tank is attached to the oil combustor, oil may be applied to the combustion part and a fire may occur. A system that extinguishes an oil combustor when taken out has been put into practical use.

As another method, an on-off valve is installed in the tank separately from the valve cap, and when the cap comes off, the on-off valve prevents the liquid from flowing out, and at least during use, the on-off valve is pushed open by the valve attached to the cap. In this way, the liquid can be supplied. (Actual exploitation 55-17184
No. 7, No. 61-34336) [Problems to be solved by the invention] By the way, even if the oil combustor is extinguished when the cartridge tank is taken out, the combustion section still maintains a high temperature. In some cases, when the cap of the cartridge tank comes off, the spilled fuel is re-ignited by the high temperature combustion part and a flame is generated.Even if it is a system that automatically extinguishes the oil combustor, the cap does not come off easily. It was necessary to change the structure of the cartridge tank.

Also, the structure that prevents the liquid from flowing out when the cap comes off the screw part of the base is safe even if the cap comes off.
The installation of a new on-off valve in the tank like No. 4336 is an extremely large-scale modification, and there is no compatibility with conventional products, and it is not possible to install the on-off valve in a cartridge tank that requires hermeticity. , When the tank was manufactured, the on-off valve was attached and then the tank was completed by welding, etc. If a defect of the on-off valve was found, repair was impossible and the tank had to be discarded.

With a general structure such as No. 55-171847 with little movement of the valve element, there is no problem when the liquid in the tank is used little by little, but the on-off valve blocks the liquid from entering the tank. It was difficult, and it took a long time to replenish, and the usability was very poor. For this reason, the idea of the basic structure has not been put into practical use even though it has become publicly known, and it has been desired to develop a special valve structure that can smoothly supply liquid without the need for modification of the cartridge tank.

Furthermore, when the cap is removed, the force of the full amount of liquid in the full tank is momentarily applied to the on-off valve, so liquid leakage cannot be prevented with a simple valve structure, and a strong closing capability is provided. However, with such a structure, the handleability at the time of replenishing the liquid is poor.

[Means for Solving the Problems] This invention relates to a cartridge tank which can be attached with an opening / closing valve afterward while using the mouthpiece or valve cap of a conventional tank as it is, and which is easy to use. Cap 4 with valve 3 on the base 2
Is detachably attached, and when the tank 1 is turned over and the cap 4 is mounted on the pan, the cap 3 has a cap 2 inside the cap 2 in the cartridge tank for pushing the valve 3 open by the pan to supply the liquid in the tank 1. Forming a protrusion 5 toward
Moreover, a pipe 6 having a diameter smaller than the opening of the base 2 and larger than the protrusion 5 is deeply inserted into the tank 1, and a valve seat 7 is formed on the inner wall surface of the pipe 6 on the base 2 side, and An opening 10 is formed in the wall surface of the pipe 6 on the tank 1 side of the valve seat 7, and a stopper 9 for an on-off valve 8 that slides using the inner wall of the pipe 6 as a guide is provided at the end of the pipe 6, and the mouthpiece of the pipe 6 is provided. Two
A flange 6'having a larger diameter than the opening of the base 2,
A tank 1 for sandwiching the end of the base 2 with the flange 6 '.
The pipe 6 inserted into the mouthpiece 2 is fixed to prevent the pipe 6 from coming off and the opening / closing valve 8 is provided with a weight 1 ".
1, the opening / closing valve 8 which moves to the valve seat 7 by the gravity of the weight 11 and the projection 5 of the cap 4 mounted on the tray are brought into contact with each other to make a liquid flow gap between the valve seat 7 and the opening / closing valve 8. To form
On the other hand, the on-off valve 8 is in close contact with the valve seat 7 due to the gravity of the weight 11 when the cap 4 falls off.

[Operation] According to the present invention having the above-described configuration, the pipe 6 having the on-off valve 8 installed therein is inserted from the tip opening of the mouthpiece 2, and the opening edge of the mouthpiece 2 rides over the inclined claw 6 ″ to form the claw 6 ″. Flange 6 '
Since the opening edge is sandwiched between the pipe and the pipe 6, and the pipe 6 is fitted to the opening edge of the tip of the mouthpiece 2, it can be attached to an existing tank and, like welding, cannot be removed. is there.

On the other hand, if the cap 4 is attached to the base 2 after replenishing the liquid, the tank 3 can be sealed because the valve 3 of the cap 4 is closed. When the tank 1 is turned over, the valve 3 remains closed, and the open / close valve 8 moves in the pipe 6 toward the valve seat 7 by the gravity of the weight 11. If the cap 4 comes off when the tank 1 is tumbled, the opening / closing valve 8 not only closes the gap with the valve seat 7, but the opening / closing valve 8 is strongly pressed against the valve seat 7 by the attached weight 11. Even if the liquid in tank 1 is about to flow out instantly when the
The liquid can be surely prevented from leaking.

When the cap 4 of the overturned tank 1 is attached to the pan, the valve 3 is opened by the pan and the opening / closing valve 8 is also opened by the protrusion 5, so that the liquid in the tank 1 can flow into the pan as usual.

Further, the pipe 6 is deeply inserted into the tank 1, and when the mouthpiece 2 of the tank 1 is directed upward, the opening / closing valve 8 is moved by the weight 11 to a position where the pipe 6 comes into contact with the stopper 9, Since the valve seat 7 is formed on the inner wall surface of the pipe 6, the opening of the pipe 6 becomes large and the tip of the hose pump can be deeply inserted into the tank like the tank without the opening / closing valve 8 and the liquid can be used regardless of the conventional product. Can be replenished.

[Embodiment] The embodiment shown in the drawings relates to a cartridge tank used in an oil combustor, wherein 1 is a cartridge tank, 2 is a screw cap of the cartridge tank 1, and 4 is a cap fitted to the screw cap 2. is there. Reference numeral 3 denotes a valve mounted in the cap 4, and the valve 3 has a projecting component 5 projecting into the mouthpiece 2 and projecting into the mouthpiece 2 on the back surface of the cap 4. Is formed.

Reference numeral 6 denotes a pipe having a diameter slightly smaller than that of the tip end opening of the mouthpiece 2 of the tank 1 and having a long length, and is made of elastic plastic. Reference numeral 6'denotes a flange 6'having a larger diameter than the opening of the mouthpiece 2 by bending the entire circumference of the tip of the pipe 6 in the outer peripheral direction.
Is a claw for sandwiching the tip opening edge of the mouthpiece 2 with the flange 6 ′, and the claw 6 ″ is formed so that the tank 1 side is inclined, and the long pipe 6 is formed from the tip opening of the mouthpiece 2. When inserted in the inner part of the tank 1, the sloping part of the claw 6 ″ is the base 2
It is located inside the flange 6'over the opening edge of the above and is fixed to the tip opening edge of the base 2 by the flange 6'and the tab 6 "so that it cannot be removed at all.

7 is a valve seat formed on the inner wall surface of the pipe 6 near the base 2;
Is a stopper attached to the end of the pipe 6 inside the tank 1,
Reference numeral 10 denotes an opening formed by cutting out a plurality of pipe 6 walls between the valve seat 7 and the stopper 9, and 8 denotes the valve seat 7 and the stopper 9.
Is an on-off valve that slides while being guided by the inner wall of the pipe 6 between them. The on-off valve 8 is formed in a bottomed tubular state, and a weight 11 is attached inside the tubular state. The weight 11 moves due to the gravity of the weight 11, and when the mouthpiece 2 of the tank 1 is directed downward, the open / close valve 8 strongly adheres to the valve seat 7.

Further, when the mouthpiece 2 of the tank 1 is directed upward, the on-off valve 8 is in contact with the stopper 9 in the pipe 6 by the weight 11, and as shown in FIG. The liquid can be replenished by deeply inserting it into the tank 1 like the conventional product having no opening / closing valve at the tip.

On the other hand, when the cap 4 of the tank 1 is attached to the tray, the valve 3 of the cap 4 is pushed open as in the conventional product, but the opening / closing valve 8 of the present invention is provided by the protrusion 5 which constitutes the valve 3 when the valve 3 is open. Since it is pushed open, the liquid in the tank 1 can flow out from the valve 3 of the cap 4 through the opening 10 of the cylindrical body 6 and the gap between the valve seat 7 and the opening / closing valve 8.

[Explanation of Effect] As described above, in this invention, the tank 1 and the valve-equipped cap 4 are not modified at all, and the conventional product is still used, and the corresponding tray can be used as it is. It is fully compatible with the tank.

Further, since the on-off valve 8 is attached with the weight 11 so that it can slide in the pipe 6 by gravity, when the tank 1 is turned over, the on-off valve 8 is biased by the weight 11 toward the valve seat 7 and the cap 4 is closed. When it comes off, the on-off valve 8 tightly adheres to the valve seat 7 to close the flow path, so that the trouble of the liquid in the tank 1 flowing out at once can be prevented, and the liquid leakage prevention function is excellent.

On the other hand, since the length of the pipe is increased, the pipe is deeply inserted into the tank 1, and the valve seat 7 is attached to the inner wall of the pipe, when the liquid is replenished to the tank 1, the tip of the hose pump is moved to the inside of the tank 1. Since the valve seat 7 can be inserted deeply and the valve seat 7 is formed on the inner wall surface of the pipe 6, the tip of the hose pump reaches the inside of the tank 1 when replenishing the tank 1 with liquid, and is convenient without being aware of the presence of the on-off valve 8. It's very good.
