Abstract

PURPOSE: To improve washability by providing a valve body of Y-shaped section, housing a bladder valve made of elastic material, and having bellows-like shape, a flange and a valve head as a bottom inside an inclined barrel, and attaching/ detaching the valve head of the bladder valve to the valve seat through operation of a handle. CONSTITUTION: A valve body 1 having a Y-shaped section is composed of metal or resin made straight barrel 1a and an inclined barrel 1b. A stepped portion is formed inside the straight barrel 1a to form a valve seat 1d perpendicularly arranged to the inclined barrel 1b. A cover 2 having a boss 2a is formed on an upper port of the inclined barrel 1b. A spindle 4 is inserted into the boss 2a of the cover 2. The spindle 4 has an upper end provided with an operation handle 5 and the other end provided with a supporter 4a. A valve head 3b of the bladder valve 3 is fitted to the supporter 4a. A flange 3a is sandwiched between the inclined barrel 1b and the cover 2. The bladder valve 3 is flexible and elastic material. Pleats A are formed on the barrel so as to increase an extention/contraction rate.

Description

Detailed Description of the Invention

[0001]

[Industrial application] Especially as a container or piping valve for handling food fluids that require strict control of cleaning or sterilization under the Food Sanitation Law. Alternatively, it is expected to have a wide range of uses for general industries.

[0002]

2. Description of the Related Art A conventional valve is structurally difficult to disassemble and assemble frequently for cleaning or sterilization, and a conventional rubber tube such as the pinch valve shown in FIG. 6 is used. There are some that have been used, but at first glance it seems easy to clean, but it is not easy to remove and assemble the rubber tube itself, and the frame structure made of cast metal is the main factor, which is extremely heavy. At the same time, the rubber tube is exposed, which is not suitable for food hygiene and environmental beautification.
In the past, no rubber valve itself has a flange provided with a sealing function.

[0003]

The bladder valve type valve according to the present invention has a sufficient function required as a valve, a simplified structure, a small number of parts, and easy disassembly and assembly. The biggest issue is the cleanability. Furthermore, it is also a challenge to reduce weight, operability and smart appearance.

[0004]

First, a lateral Y-shaped valve body 1 made of a metal or resin straight body portion 1a and a slant body portion 1b corresponding to a fluid condition is provided. A valve seat 1d having a step is formed at an angle so as to be able to intersect the slant body portion at a right angle, and a lid 2 with a boss 2b is provided at the upper opening of the slant body portion. (B) A spindle 4 is passed through the boss of the lid, and a handle 5 for operation and a supporter 4a at the tip are provided on the spindle.
C) Then, the spindle with the supporter is fitted into the bladder valve 3 with the flange 3a, and the whole is inserted into the slant barrel portion 1b and attached with the lid 2 to complete the structure. D) The bladder valve is a sac-like shape made of a flexible elastic material and has a valve head 3b at the bottom, which is made thicker to give elasticity to enhance the sealing property. It is characterized in that a fold A for increasing the amount is provided and a flange 3a having a packing function is provided at the mouth.
(E) Both ends of the main body straight part are structured so that they can be connected to a container or piping by means of flanges or joints 1c. Alternatively, a screw or bayonet method is also possible.
F) Further, by providing an oblique step on the lower surface of the straight body part and using this as a valve seat, it is possible to eliminate the residual fluid. Moreover, the structure is such that clogging does not occur at all.

[0005]

After the bladder valve type valve constructed as described above is connected to a container or a pipe, a) a bladder valve which is pushed into the inside while rotating the spindle 4 by operating the handle 5 and is also incorporated in the oblique barrel 3, supporter 4
By directly pressing the valve head 3b against the valve seat 1d via a, the fluid can be completely shut off, and by returning it to the original state, the fluid can be passed. B) In addition, disassembly and assembly during cleaning is done by removing the valve from the container or piping and then removing the lid 2 at the upper mouth of the slanted body so that the bladder valve can be completely removed. , A bladder valve and a lid with a built-in spindle.
Therefore, it is sufficient to wash these wetted parts carefully, and a very simple operation is sufficient. C) Reassembly can be performed very easily as well.

[0006]

[Example] The material of the body and the bladder valve that come into contact with the fluid are
It is necessary to consider corrosion resistance or to meet food hygiene standards. Further, in carrying out the present invention, the following can be done.

As shown in FIG. 4, the bladder valve is divided into a valve head portion and a body portion, so that the function of the bladder valve type valve according to claim 1 can be provided.

As shown in FIG. 5, it is also possible to adopt a structure in which the main body straight body portion is an elbow type, a valve seat is provided inside, and the spindle and the bladder valve are operated linearly with respect to the body portion. or,
In this case, it is possible to direct the fluid in the desired direction of 360 degrees depending on the connection method.

At the same time, the main body may be provided with a plurality of discharge branch ports, or may be constructed as branch ports having different diameters. Alternatively, it can be an open mouth.

In particular, when the food hygiene law requires strict cleaning, the structure is extremely simple, so that the cleaning of the valves can be very easy as well as the cleaning of the containers. The design can be simplified and the weight can be reduced, and the operability and cost can be reduced. Therefore, it can be used in all fields.
