PURPOSE:To immediately flush a supply system in its entirety by communicating a discharge port with a chamber in a valve housing at a position where a valve member is moved to the outside of a container. CONSTITUTION:A valve element 4 disposed reciprocally in a valve housing 3 is moved inward of a container 2 so as to allow liquid to flow from a dis charge port 30a of a supply passage 30 in the valve element 4 toward the sur face of the inner wall 2a of the container 2, and accordingly, the liquid flows down along the surface of the inner wall and is therefore fed. Accordingly, it is possible to restrain gas from being mixed with the liquid. When the supply of the liquid is completed, the valve element 4 is moved outside of the container 2 so that the discharge port 30a of the passage 30 in the valve element 4 is communicated with a chamber 10 in the valve housing 3 so as to be communicat ed with a flushing system while being isolated from the container 2.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a liquid supply valve device, and more specifically, when supplying liquid to a container, it enables liquid to flow down the wall surface with a simple structure, and also ensures reliable cleaning. This invention relates to a liquid supply valve device capable of

(Prior art) For example, in the production process of the chemical industry, liquid transfer,
Storage etc. are generally indispensable operations. Especially when the production process is carried out in batch mode, the reaction,
When supplying a liquid such as raw material liquid to a container for purposes such as mixing, dissolving, and storage, it may be supplied to a sealed container.

In such a case, as shown in FIG. 10, there is a container equipped with a hose setting device 101 on the top of a sealed container 100. In this case, when supplying liquid, the lid opening/closing cylinder 102 opens 1i 103 of the container 100, the hose setting cylinder 104 is activated, and the supply nozzle 10 provided on the hose 106 of the supply system 105 is connected to the drain packet 10.
8 to the opening, and the liquid is supplied from the supply liquid container 109 to the container 100. When the supply of liquid is completed, the hose setting cylinder 104 is actuated to supply the supply nozzle 1.
07 to the drainage packet 108 side and close the lid 103 of the container 100. When cleaning the supply system 105, the valve 1!0 is operated to inject the cleaning liquid from the injection nozzle 111 into the supply liquid container 109.
It is designed to perform cleaning.

(Problems to be Solved by the Invention) By the way, when supplying with this hose setting device 101, by injecting the cleaning liquid into the supply liquid container 109, it is possible to wash the entire supply system 105 with water. However, when the liquid is supplied, it is discharged and injected from a high place, and it is impossible to avoid mixing of air into the liquid, foaming, and scattering.

Therefore, it is not suitable for supplying raw material liquids having a low flash point or for use in systems where foaming within a container is undesirable. Also, when the supply nozzle 107 is on standby after supply and cleaning are completed,
The supply system 105 is open to the surrounding environment, and there is also a problem in keeping the system clean. Furthermore, during the supply of liquid, the container 10
0 M2O3 becomes open, making it impossible to seal the container 100.

For this reason, as shown in FIG. 11, there is a device that uses a fixed vent nozzle, which is equipped with a vent nozzle 112 on the side of the container 100, and allows the liquid to flow down along the inner wall, and after supplying, the liquid is By switching the direction valve 113, the supply system 105 is cleaned. Since this type of liquid can be supplied along the wall surface of the liquid through the vent nozzle 112, it is possible to prevent mixing of gas and foaming during supply, which are problems associated with hose setting devices. In this way, wall flow is the only alternative to submerged supply, but when considering the cleaning of the supply system, it is not possible to clean the vent nozzle part, and therefore it is not possible to clean the vent nozzle immediately after supply is finished. Depending on the physical properties of the liquid, it may be difficult to use it as a normal supply system from the next time onwards. In particular, in the case of gelatin-containing additive liquids used in the production of photosensitive materials, the supply system cannot be cleaned, leading to contamination and the generation of bacteria, which in turn reduces the performance of the coating liquid.

This invention was made in view of the above-mentioned circumstances, and by supplying liquid by flowing down the inner wall surface of the container, it is possible to prevent gas mixture, foaming, and scattering, and to prevent the supply of liquid from occurring between the container and the supply after supplying the liquid. It is an object of the present invention to provide a liquid supply valve device in which a system can be isolated in a hermetically sealed state and the entire supply system can be quickly cleaned.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a liquid supply valve device that supplies liquid by flowing it down along the inner wall surface of a container, in which the container is connected to a cleaning system. A valve box having a chamber is provided, and a valve body having a supply channel for supplying liquid into the container is reciprocatably provided in the valve box, and a discharge port of the supply channel flows out toward the inner wall surface of the container. The discharge port is configured to be in contact with the inner wall surface of the container at a position where the valve body moves to the inside of the container, and to communicate with the chamber of the valve body at a position where the valve body moves to the outside of the container. It is characterized by

(Function) In this invention, when the valve body provided in the valve box so as to be reciprocally movable is moved inside the container and the liquid is caused to flow out from the discharge port of the supply channel of the valve body toward the inner wall surface of the container, The liquid is supplied by flowing down along the inner wall surface. Therefore, it is possible to suppress the mixing of gas into the liquid and the bubbling and scattering of the liquid due to the immersion operation. Further, when the supply of liquid is finished, the valve body is moved to the outside of the container. Thereby, the discharge port of the supply channel of the valve body is communicated with the chamber of the valve box, connected to the cleaning system, and isolated from the inside of the container. Since it is isolated from the container in this way, the entire supply system can be cleaned by supplying the cleaning liquid to the supply system.

(Example) Next, an example of the present invention will be described in detail based on the accompanying drawings.

1 to 3 show a liquid supply valve device showing an embodiment of the present invention, in which FIG. 1 is a sectional view during supply, FIG. 2 is a sectional view taken along line II-II in FIG. 1, and FIG. FIG. 3 is a cross-sectional view during cleaning.

It is supplied by flowing down along the inner wall surface of the side wall 2a, and has a valve box 3 and a valve body 4. The valve box 3 has a chamber portion 5 connected to a cleaning system and a cylinder portion 6 that constitutes a drive mechanism for the valve body 4.

A chamber 10 is formed in the chamber portion 5 by connecting a chamber mounting body 7 and a chamber cylindrical body 8 with a tightening bolt 9. This chamber attachment body 7 is applied to a bracket 11 welded to the side wall 2a of the container 2 via a gasket 12, and is tightened and fixed with a tightening bolt 13. A communication passage 10a communicating with the chamber 10 is formed in the chamber cylindrical body 8, and a connection pipe 14 is press-fitted into this communication passage 10a, and a cleaning system is connected through this connection pipe 14.

A cylinder 18 is formed in the cylinder portion 6 by connecting a cylinder mounting body 15 and a cylinder cylindrical body 16 with a tightening bolt 17. This cylinder mounting body 15 is a chamber part 5
A tightening bolt 20 is attached to the chamber cylindrical body 8 through the annular body 19.
An annular body 21 is fixed on the opposite side of the cylinder body 16 with a tightening bolt 22 to prevent the guide ring 23 from being removed.

A valve body 4 is inserted into the valve box 3 formed in this manner so as to be reciprocally movable, and a piston portion 4a of the valve body 4 is slidably provided in the cylinder 18.
25 are divided. This - side hydraulic pressure chamber 24 is connected to the other side hydraulic pressure N from a passage 26 formed in the cylinder mounting body 15.
Pressure fluid is supplied to 25 from a passage 27 formed in the cylinder body 16, thereby causing the valve body 4 to reciprocate.

The head 4b of the valve body 4 protrudes into the container 2, and a cap 29 having an annular seal member 28 is screwed onto the head 4b. The annular seal member 28 is made of synthetic resin such as polytetrafluoroethylene, and a portion 28a of the annular seal member 28 is made of a synthetic resin such as polytetrafluoroethylene.
It protrudes toward the inner wall surface of the side wall 2B, and the third
As shown in the figure, the valve body 4 presses against the inner wall surface of the HJ 2 a on the side of the container 2 to regulate the position and seal, thereby blocking the inside of the container 2 and the supply flow path 30 of the valve body 4. It has become.

The position of the valve body 4 when moving inside the container 2 is controlled by pressing the annular seal member 32 held on the valve body 4 by the annular holding member 31 against the chamber attachment body 7, and in this state, the annular The sealing member 32 seals and isolates the chamber 10 from the inside of the container 2 .

The annular seal member 32 is also made of synthetic resin such as polytetrafluoroethylene.

The mechanism for reciprocating the valve body 4 operates smoothly between the end point and the point of sliding, and the annular seal member 32.28
Any structure may be used as long as it is a mechanism that allows each of the seals to repeatedly and repeatedly hang in close contact with the seal wall surface. Further, the driving force may be manual, about MF4, or electric drive. For example, in addition to the above-mentioned hydraulic piston type, there are hydraulic piston type, compressed air piston type, combination of compressed air or oil pressure and a biasing member such as a spring as restoring force, electric or manual crank type, and binion rack type. Any method such as cam or reciprocating rod method can be used.

The supply channel 30 of the valve body 4 is formed in the axial direction at a position displaced upward from the axis, and the rear end of the valve body 4 is connected to a supply system (not shown). The discharge port 30a formed in the head 4b of the valve body 4 bends the supply channel 30 at a predetermined angle, and
The liquid is heated and pressurized toward the inner wall surface of the side 92a.

This discharge port 30a contacts the inner wall surface of the side wall 2a of the container 2 in the forward position shown in FIG. 1 when the valve body 4 has moved into the container 2, and as shown in FIG. It communicates with the chamber 10 in the reverse position shown in FIG.

The diameter of the discharge port 30a, the angle α of the side wall 2a of the container 2 with respect to the inner wall surface, and the length of the discharge port are arbitrarily set depending on the viscosity of the liquid, the supply flow rate, etc., within a range in which the liquid flows down along the wall surface. . Further, the mounting position of the liquid supply valve device 1 is not limited to the side wall 2a, but can be mounted at any position within the range where the liquid can flow down along the wall surface.

Therefore, as shown in FIG. 1, when pressure fluid is supplied to the hydraulic chamber 25 of the cylinder portion 6 of the valve box 3 through the communication passage 27, the valve body 4 moves inward of the container 2, and the valve body 4 moves toward the inside of the container 2. Head 4b of body 4
protrudes into the container 2. At this time, the supply channel 30 of the valve body 4
The discharge port 30a is in contact with the inner wall surface of the side wall 2a of the container 2, while the annular sealing member 32 of the valve body 4 is in contact with the chamber attachment body 7 to seal, thereby sealing the inside of the container 2 and the chamber 1.
0 is blocked. When fluid is supplied to the supply channel 30 in this state, the liquid is guided to the discharge port 30a of the supply channel 30, flows out toward the inner wall surface of the container 2, and flows down along the wall surface.

For this reason, when supplying the liquid, gas is prevented from being mixed into or drawn into the liquid, and furthermore, foaming and liquid scattering are reduced.

When the supply of liquid is finished, pressure liquid is supplied to the hydraulic pressure chamber 24 from the communication passage 26 of the cylinder part 6 of the valve box 3, and the valve body 4 moves to the outside of the container 2 as shown in FIG. Then, the annular sealing member 28 provided on the cap 29 of the valve body 4 contacts and seals the inner wall surface of the side wall 2a of the container 2, and the container 2
The supply flow path 30 of the valve body 4 is cut off from the inside. At this time, the discharge port 30a of the valve body 4 is connected to the chamber 10 of the chamber portion 5.
It communicates with Therefore, when the cleaning liquid is supplied from the upstream side of the supply flow path 30 of the valve body 4, the cleaning liquid flows from the discharge port 30a to the chamber 10 and is discharged from the connecting pipe 14, and the cleaning liquid flows into the valve body 4.
The supply flow path 30 and the discharge port 30a can be cleaned, and the supply system can be completely cleaned.

This cleaning may be performed by supplying the cleaning liquid into the chamber 10 from the connecting pipe 14 side and supplying it to the supply channel 30 from the discharge port 30a of the valve body 4.
