2. Description of the Related Art Conventionally, a piping structure using a T-shaped pipe or a vent pipe has often been adopted in order to branch a fluid flowing from one direction into two directions. However, there are many problems such as a large amount of fluid accumulating in the pipe line when the control valve is closed, which makes it easy for bacteria and the like to multiply, the pipe work is troublesome, and a large space is required for the pipe. there were.

Therefore, recently, as shown in FIG. 37, the inlet line of another fluid controller (B) is integrally formed perpendicularly to the outlet line of the fluid controller (A) arranged in the horizontal direction. Although a branch type fluid controller having a connected structure has been often used, even with this branch type fluid controller,
Problems remain such that the accumulation of fluid in the pipeline cannot be completely eliminated, and the space required for the piping is relatively large.

As a technique for solving such a problem, for example, a technique disclosed in Japanese Patent Application Laid-Open No. Hei 5-312813 has been proposed. The disclosed technology provides first and second passages in the left-right direction and a third passage in the up-down direction in one valve box, and partitions the first and second passages by a first partition wall.

Claims (4)

[Claims] 1. The display device has a substantially triangular prism shape having two substantially right-angled triangular surfaces parallel to each other, wherein the two surfaces are respectively front and rear surfaces and one surface forming a right angle of the right-angled triangle is disposed as a lower surface. A valve box having a first opening on a front surface, a second opening on a rear surface, and a third opening on a lower surface; a first valve body disposed on a surface forming the hypotenuse of the right triangle; A second valve body disposed on the other surface forming the right angle of the right triangle, wherein the first and second valve bodies are communicated by a connection passage having no projection provided inside the valve box. Wherein the first opening and the second opening are arranged on the same axis, and a passage from the first opening is branched in two directions in the valve box. One of the passages is capable of communicating with the second opening through the first valve body, The two-way branched fluid controller is characterized in that the other passage can communicate with the third opening through the second valve body. 2. It has a substantially triangular prism shape having two substantially right-angled triangular surfaces parallel to each other, and when the two surfaces are respectively arranged as front and rear surfaces, and one surface forming a right angle of the right-angled triangle is arranged as a lower surface. A valve box having a first opening on a front surface, a second opening on a rear surface, and a third opening on an upper portion; a first valve body disposed on a surface forming an oblique side of the right triangle; A second valve body disposed on the other surface forming the right angle of the right triangle, wherein the first and second valve bodies are communicated by a connection passage having no projection provided inside the valve box. Wherein the first opening and the second opening are arranged on the same axis, and a passage from the first opening is branched in two directions in the valve box. One of the passages is capable of communicating with the second opening through the first valve body, The two-way branched fluid controller is characterized in that the other passage can communicate with the third opening through the second valve body. 3. It has a substantially triangular prism shape having two substantially right-angled triangular surfaces parallel to each other, wherein the two surfaces are respectively front and rear surfaces, and one surface forming a right angle of the right-angled triangle is disposed as a lower surface. A valve box having a first opening at an upper portion, a second opening at a lower surface, and a third opening at a front surface; and a first valve body disposed on another surface forming a right angle of the right triangle. A second valve body disposed on a surface forming the hypotenuse of the right triangle, wherein the first and second valve bodies are communicated by a connection passage having no projection provided inside the valve box. Wherein the first opening and the second opening are arranged on the same axis, and a passage from the first opening is branched in two directions in the valve box. One of the passages is capable of communicating with the second opening through the first valve body, The two-way branched fluid controller is characterized in that the other passage can communicate with the third opening through the second valve body. 4. It has a substantially triangular prism shape having two substantially triangular surfaces parallel to each other. When the two surfaces are arranged as front and rear surfaces and one surface constituting the triangle is arranged as a lower surface, a second surface is formed on the rear surface. A valve box having a first opening, a second opening and a third opening on the front surface, and first and second valve bodies respectively disposed on the other two surfaces constituting the triangle; The first and second valve bodies are two-way branched fluid controllers connected by a projection-free connection passage provided inside the valve box, wherein the first opening and the second opening are coaxial. While being arranged on a line, a passage from the first opening is branched in two directions in the valve box, and one passage is made to be able to communicate with the second opening through the first valve body, and Can communicate with the third opening through the second valve body. A two-way branch fluid controller.
