Abstract

PURPOSE:To quickly replace fluid in a sanitary pipe, prevent fluid from remaining in the pipe, and significantly reduce portions to be cleaned and sterilized by providing a fluid partition panel in the pipe to make the fluid branch and bypass in the pipe. CONSTITUTION:In sanitary pipes used in the fields manufacturing products such as medicines, foods, electronic parts, etc., whose pollution and quality deterioration must be restrained, in the case where a pipe is used as a valve straight pipe system, for example, comprising a valve 3 connected to one end of a straight pipe 1, while the valve 3 is opened, fluid is made to flow on both sides of a partition panel 2. On the other hand, while the valve 3 is closed, one side 2a of the partition panel 2 is made to be a passage through which fluid flows toward the valve 3, and the other side 2b is made to be a passage through which fluid make a U-turn from the valve 3. This constitution allows fluid to always flow in either case where the valve 3 is opened or closed, preventing fluid from remaining in the port of connection of the straight pipe 1 and valve 3, in which fluid is liable to remain with the valve 3 closed in the case of a conventional system.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a T tube, a Y tube, a cross tube,
Regarding piping elements such as elbows, socket pipes, and valve direct connection pipes, especially so-called sanitary pipes used in the manufacturing process in the field of manufacturing products such as pharmaceuticals, foods, electronic parts, etc. where contamination and quality aging must be suppressed. It is about.

Further, the present invention relates to a transportation pipe for gas, liquid, solid and a mixture thereof.

[0003]

2. Description of the Related Art Contamination by foreign substances, cross-contamination between process constituents, generation of fungi, or air admixture in a manufacturing apparatus connected by sanitary piping will significantly impair product quality. . In order to prevent this, conventionally, in many cases, pipes and devices were usually disassembled, washed and sterilized in batch units, and then reassembled and reused.

However, such disassembling and assembling work requires enormous labor and time, and contamination in the working process may occur. Therefore, in recent years, CIP (Clean-in-Place,
In-place cleaning method) and SIP (Sterilization-in-Plac)
e, stationary sterilization method) is drawing attention and is becoming widespread. CIP,
What is common to SIP is that without dismantling the pipes and equipment, the supply of raw materials for manufacturing is temporarily stopped, and the fluid for cleaning or sterilization is passed to clean and sterilize the inside of the piping and equipment. It is to be. Specifically, in the CIP, water washing, compressed air draining alkaline liquid cleaning, compressed air liquid draining water cleaning, compressed air draining acid solution cleaning, compressed air draining, water cleaning, compressed air draining, etc. are sequentially executed, and in SIP, high pressure It is becoming more common to perform steam sterilization, dry heat sterilization with hot air, gas sterilization, etc. in combination with the above-mentioned cleaning step.

In carrying out these CIP or SIP, the most important thing is to pre-engineer the pipes and equipment so that there will be no reservoir for foreign matter process composition substances or various fluids. , CIP and SIP setting conditions.
Normally, when a branching member such as T, Y, and cross pipe is used in combination with a valve and a cock, a basin is likely to occur. Therefore, without using T, Y, and cross pipe, the supply system passage and the discharge system The piping method in which the passage is piped for each type of feed and discharge is frequently used, and therefore the amount of piping of the entire device increases and the piping structure becomes complicated.

Many products called sanitary type pipes, sanitary type branch pipes, and sanitary type valves have been commercialized both in Japan and overseas. However, these are simply smoothing the inner surface of the member, welding part or fitting. It is merely a simplification of the shape of the joint. Furthermore, equipment such as CIP equipment or RO water production equipment, UF water production equipment, distilled water production equipment, chemical liquid adjustment equipment, etc. have been put on the market, but these have been considered in terms of engineering from the viewpoint of preventing retention. However, since existing piping members are used, it often takes time and effort to clean and sterilize the branch part and the fitting part from the user's side.

[0007]

As described above, T,
If the piping of the equipment is performed without using the branching pipe members such as Y and cross pipes, the piping amount increases and the piping structure becomes complicated. On the other hand, when the branching members such as T, Y and cross pipes are used, Inevitably, there is a contradiction that the fluid that has flowed earlier stays in the reservoir and is not replaced with the fluid that has flowed afterwards, which causes contamination and deterioration of the product. Moreover, if there is a pool of fluid, it takes a long time to replace fluid such as chemical liquid and air, chemical liquid and cleaning liquid, cleaning liquid and air, air and steam, hot air, gas, cleaning water and steam, and as a result, CIP, There are problems that the reachability of SIP is insufficient and the required time becomes long.

[0008] Therefore, an object of the present invention is to provide a novel piping member in which a fluid reservoir is not generated, that is, a fluid is replaced quickly.

[0009]

The pipe members of the present invention, that is, members such as T, Y, cross pipes, elbows, socket pipes, valve direct connection pipes, etc., are arranged along the flow direction of the fluid, that is, the axial direction of the pipes. The feature is that a partition plate is provided.

In a pipe member used for branching a pipe such as a T, Y or cross pipe, a partition plate is not provided along all the flow directions of the fluid, but a partition plate is provided only in a part thereof. There is. This partition plate constitutes a dividing surface that divides the flow path along the flow direction, and is preferably provided so as to bisect the flow path so as to match the maximum diameter.

The term "fluid" as used herein refers to all objects transported by a pipe. That is, liquids, gases, solids such as powders, and mixtures thereof are collectively called fluids. This partition plate may be added to an existing piping member or may be manufactured integrally with the piping member.

[0012]

[Operation] As the simplest case, a straight pipe is shown in Fig. 1.
Will be described. When the valve 3 is connected to one end of the straight pipe 1, the fluid flows in the same direction on both sides of the partition plate 2 as shown in FIG. When the valve 3 is closed, one side 2a of the partition plate 2 serves as a forward path that flows toward the valve 3 and the other one side 2b serves as a return path that makes a U-turn from the valve, as shown in FIG. As a result, regardless of the open / closed state of the valve 3, the fluid always flows into the connection port between the straight pipe 1 and the valve, which has been the reservoir of the fluid in the state where the valve 3 is closed in the past, and the reservoir is eliminated.
