 INDUSTRIAL APPLICABILITY The present invention is useful when transferring seasonings such as mayonnaise, ketchup, and tartar sauce, which have a relatively high viscosity, and seasonings mixed with granules, etc., from a large container to a small container. The present invention relates to an automatic opening / closing valve.

[0002]

[Prior art]

 Conventionally, various types of automatic opening / closing valves have been proposed and put to practical use as automatic opening / closing valves used when transferring liquids such as water and liquor having relatively low viscosity from large containers to small containers. The automatic opening / closing valve used when transferring seasonings such as the above-mentioned mayonnaise, ketchup, and tartar sauce, which have high viscosity, and seasonings mixed with granules, etc., from a large container to a small container is fully satisfactory. There is nothing to do. However, the consumption of mayonnaise, etc. is increasing remarkably today, and it is considered to be extremely useful if a useful automatic opening / closing valve is developed to transfer from a highly viscous liquid container. To be

[Problems to be solved by the device]

 Therefore, the problem to be solved by the present invention is to provide a useful automatic opening / closing valve for use when transferring a liquid material having a relatively high viscosity or a liquid material mixed with granules from a large container to a small container. It is to be.

[0004]

[Means for Solving the Problems]

 The present invention has been made for the purpose of solving the above problems, and its configuration is a hollow cylindrical body made of a hard material such as a hard synthetic resin or a metal, and a drainage pipe is locked to the outer surface of the upper part thereof. A stopper is formed, and one or a plurality of holes communicating with the inside of the hollow are provided below the engaging portion, and a lower portion is formed with a stopper portion having a hemispherical shape, and a flexible rubber or the like. A tubular body made of a flexible body, the upper part of which is locked to the locking part of the plug body, and the lower part of which is closely fitted to the plug part of the plug body and which is fitted into the plug body. When the drainage pipe is in close contact with the outer periphery of the stopper and the valve is closed and the liquid substance is pumped into the hollow inside of the stopper, the drainage pressure expands the drainage pipe to A flow path is formed between the drainage pipes and the valve is opened. If stopped, it is characterized in that the drain pipe has to be restored.

Thus, a vertical groove is formed in the vicinity of the hole provided in the center of the stopper, and the surface surrounding the hole is formed into a mirror surface, and the stopper is hemispherical. The surface of the part may be roughened.

【Example】

 Next, an example of implementation of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a cross section of a drainage pipe according to an example of the present invention, FIG. 2 is a front view of the left half of the stopper body in cross section, and FIG. 3 is a front view of the drainage pipe.

In the figure, reference numeral 1 denotes a plug, which is a hollow cylindrical body made of a hard material such as a hard synthetic resin or a metal. A locking part 4 for locking the drainage pipe, which is formed in the connection part 2 connected to the supply pipe (not shown), and the partition flange 3 is interposed under the connection part 2 to form the upward projecting ridges 4a in a plurality of annular shapes. Is formed on the outer surface of the stopper body 1 and the lateral holes 6 and 6 ′ communicating with the internal hollow passage 5 of the stopper body 1 are formed below the locking portion 4. Is formed, and a substantially hemispherical solid plug portion 8 is provided below the holes 6 and 6 '. Generally, the outer peripheral surface of the portion where the holes 6 and 6'are provided, or at least the periphery of the holes 6 and 6 ', is mirror finished, and the surface of the plug 8 is roughened. Further, the number of the groove 7 may be one or more, and the number of the hole 6 may be one.

Reference numeral 9 denotes a drainage tube having a high elasticity such as rubber, which is formed in a tapered shape, an upper part thereof is formed on a fitting part 10 to be fitted on the plug body 1, and a lower part of the taper is formed on a draining part 11. The upper portion of the fitted portion 10 is pressed and locked to the locking portion 4 of the plug 1 so as to be attached to the plug 1. The drainage pipe 9 is normally in a state in which the fitted portion 10 is in close contact with the plug 1 and the valve is closed, and when the liquid substance is pumped to the plug 1, the passage 5 A material that has elasticity so that it expands due to the hydraulic pressure flowing out of the holes 6 and 6 ′ through the holes and restores when the hydraulic pressure disappears is used.

The automatic opening / closing valve of the present invention comprises the plug 1 and the drainage pipe 9 described above, and its operation is as follows. That is, if a liquid material supply pipe is connected to the connecting portion 2 of the stopper 1 and liquid material such as mayonnaise or ketchup is pumped into the inside of the stopper 1 from the supply pipe, the liquid material will be discharged from the passage 5 through the hole. 6, 6 ', and when the hydraulic pressure increases, the fitted portion 10 of the drain pipe 9 expands due to the discharged hydraulic pressure, as shown by the dotted line in FIG. Since a gap is created between the liquid substance and the valve 1 and the valve is opened, the liquid substance is discharged to the outside from the drainage portion 11 through the gap and the concave groove 7, and the liquid substance from the supply pipe is also discharged. When the supply is stopped, the fluid pressure disappears, so that the fitted portion 10 of the drainage pipe 9 is restored and comes into close contact with the plug body 1, and particularly strongly contacts the plug portion 8 of the plug body 1, so that the valve is closed. Then, there is no possibility that the liquid will leak. In particular, the mirror surfaces formed around the holes 6 and 6'increase the close contact between the drainage pipe 9 and the plug body 1, thereby ensuring a smooth outflow stop of the liquid. On the other hand, the rough surface formed in the plug portion 8 and the concave groove 7 prevent close contact between the plug body 1 and the discharge pipe 9 to help the liquid material flow out quickly.

[0010]

[Effect of device]

 The present invention is as described above, and when the liquid is not delivered to the stopper, the drain pipe is in close contact with the stopper and the valve is closed. The drainage pipe expands due to hydraulic pressure, creating a gap between the drainage pipe and the valve, the valve is opened, the liquid substance is discharged from the lower part of the drainage pipe, and the pumping of the liquid substance is stopped. By doing so, the drainage pipe is brought into close contact with the stopper again so that the valve is closed, so that even if the liquid substance is highly viscous, such as mayonnaise or ketchup, it can be smoothly inserted into a large volume. It is very useful when transferring from a container to a small container, and its construction is simple, easy to manufacture and inexpensive.
