DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fluid controller,
More specifically, a fluid flowing in one direction can be branched in two directions on the way, and the piping work for branching is extremely easy and can be installed in a small space, and the accumulation of fluid inside occurs. The present invention relates to a fluid controller having no.

2. Description of the Related Art Conventionally, for example, in order to branch a fluid flowing in a horizontal direction downward in the middle, a packing (P) is provided between horizontal flow paths (A) and (A) as shown in FIG. T
A piping structure in which a mold joint (T) is connected by a clamp (C), and a diaphragm valve (D) for adjusting a flow rate of a fluid flowing through a branch passage (B) is connected downstream of the T-shaped joint (T). Often adopted. However, the conventional piping structure as shown in FIG. 5 is limited in its application because the connection work at the time of piping is troublesome and troublesome, and the space required for installation is large, so that it may not be used in places where the piping is crowded. There was a problem that there was. Also, T
When the diaphragm valve (D) is closed, a large amount of fluid accumulates in the portion of the inlet from the branch inlet to the diaphragm valve (D) (the portion indicated by the grid in the drawing) because the U-shaped branch portion becomes long. There was also a problem of being able to do it.

In view of such circumstances, an integrated branch controller having a T-shaped flow path as shown in FIG. 6 has recently been used in some cases. Although not shown, a diaphragm valve body is attached to the valve seat (Z), the opening (F) is provided with the flow paths (R1) and (R2), and the opening (G) is provided with the branch path (R).
And 3) can be communicated with each other via the diaphragm valve body. The branch controller as shown in FIG. 6 does not require a troublesome connection for branching, and is extremely easy to perform piping work.
It is possible to solve many of the problems of the conventional technology.

[0004]

However, in the branching controller shown in FIG. 6, the fluid flowing in a certain direction can be branched in one direction halfway, but cannot be branched in two directions. Therefore, for example, when it is desired to branch a fluid flowing in the horizontal direction in the vertical direction, two branch controllers must be used, and after all, a troublesome connection work is required at the time of piping, and the installation space is large. There was a problem of becoming. The present invention has been made in order to solve such a problem, and it is possible to branch a fluid flowing in one direction in two directions halfway, and furthermore, it is possible to perform piping without requiring a troublesome connection for branching. An object of the present invention is to provide a fluid controller which is extremely easy to work, can be installed in a small space, and does not generate fluid accumulation inside.

[0005]

According to the present invention, the first flow path and the second flow path are formed so as to be directed in the vertical direction, and the third flow path and the fourth flow path are formed so as to be directed in the horizontal direction. The first flow path and the second flow path can be communicated from one opening of the valve seat to the other opening through the diaphragm, and the third flow path and the fourth flow path are provided in the one opening. The fluid controller is characterized in that the fluid controller is formed so as to communicate with the first flow path and branch off in a T-shape with respect to the first flow path.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fluid controller according to the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway front view showing a preferred embodiment of a fluid controller according to the present invention, and FIG. 2 is a side sectional view thereof. In FIG. 1, the portion above the valve seat, that is, the diaphragm valve main body, is not shown for easy understanding of the configuration of the present invention. In the fluid controller according to the present invention, as shown, the first flow path (1) and the second flow path (2) are in the vertical direction, and the third flow path (3) and the fourth flow path (4) are horizontal. It is formed so as to direct each direction. In this specification,
The direction of the first flow path (1) and the direction of the second flow path (2)
The expression of the directions of the third flow path (3) and the fourth flow path (4) as a horizontal direction is a convenient expression for clarifying the arrangement relation of the respective flow paths, and is used in actual use. In the above, for example, the first flow path (1) and the second flow path (2)
Of course, it is also possible to make the flow path (3) and the fourth flow path (4) point in the vertical direction.

The first flow path (1) and the second flow path (2) communicate from one opening (6) of the valve seat (5) to another opening (8) via a diaphragm (7). It is possible and the third
The flow path (3) and the fourth flow path (4) communicate with the first flow path (1) provided in one opening (6) and form a T-shape with the first flow path (1). The branch is formed. With this configuration, the fluid flowing from the third flow path (3) or the fourth flow path (4) branches off to the first flow path (1) and flows.
The second flow path (2) flows from one opening (6) to another opening (8) by the upward operation of the diaphragm (7).
Distribute to

At this time, as shown in FIG.
It is preferable that the diameter of (7) is equal to the inner diameter of the first to fourth flow paths. The reason is as shown in FIG.
When the inner diameter of the branch path (R3) is smaller than that of the branch path (R3), the flow path (R1) and (R2) are arranged in the vertical direction.
A part of the fluid flowing from (1) or (R2) to the opening (G) via the valve body accumulates at the lower end (G1) of the opening (G). This is because if this is made equal to the inner diameter, this can be prevented.

In the example shown in FIG. 2, the operating mechanism for expanding and contracting the diaphragm is a main-rotating operating mechanism of a handle rotation type. However, in the present invention, a pneumatic actuator may be used as shown in FIG. Alternatively, other known operation mechanisms may be used, and there is no particular limitation.

FIG. 4 is a diagram showing an example of a use state of the fluid controller according to the present invention. As shown in the drawing, when the fluid controller according to the present invention is used, it is possible for one fluid controller to branch a fluid flowing in the horizontal direction halfway in the vertical direction. Therefore, it is possible to save labor for piping work, and it is possible to perform piping in a small space. In addition, unlike the case where a conventional T-shaped joint is used, there is almost no fluid reservoir in the pipe, so that the flowability can be improved. Although the fluid controller shown in FIG. 3 is used in the illustrated example, it goes without saying that the fluid controller shown in FIG. 2 can be used in the same manner.

[0011]

As described above, according to the present invention, the first flow path and the second flow path are formed so as to be directed in the vertical direction, and the third flow path and the fourth flow path are formed so as to be directed in the horizontal direction. The first
The flow path and the second flow path can be communicated from one opening of the valve seat to another opening through the diaphragm, and the third flow path and the fourth flow path are provided in the one opening. The fluid controller is characterized by being formed in communication with the first flow path and branched in a T-shape with respect to the first flow path, and has the following effects.

That is, since the fluid flowing in one direction can be branched in two directions halfway by using only one controller, laborious piping connection for branching is not required and the piping work can be saved. Can be In addition, since the space required for installation is small, it can be used in places where piping is crowded, and has a wide application range. Furthermore, since a long connecting pipe for branching such as a T-shaped joint is not required,
There is no accumulation of fluid inside the flow path.
