の問題も生じる。(b) Prior art When controlling the flow rate of fluids such as liquids and gases,
Flow control valves in which a valve body such as a spool is mechanically moved are commonly used. The valve body is housed within the valve casing, and fluid is guided and circulated through the flow path of the valve casing. Therefore, it is well known that by moving the valve body, the flow rate in the flow path of the valve casing can be controlled.
However, since this type of flow control valve requires mechanical movement of the valve body, problems such as friction and seizure between the valve body and the valve casing are inevitable. When impurities such as dust get stuck between the valve casing and the valve body, the valve body may not move smoothly, causing problems with flow control. When the valve body is moved by a driving means such as a cylinder, problems such as friction and seizure of the driving means arise.

Moreover, it is an object of the present invention to provide a flow rate control valve that is not affected by impurities such as dust.

In order to reduce the flow rate in the flow path 2 of the valve casing 1, fluid pressure such as hydraulic pressure or air pressure may be supplied to each rubber tube 3 by a fluid pressure supply source. 1st
As shown in the figure, each rubber tube 3 is expanded by fluid pressure and protrudes into the flow path 2. Therefore, the flow rate of the flow path 2 can be reduced. In order to increase the flow rate in the flow path 2, the fluid pressure in each rubber tube 3 may be removed. As shown in FIG. 2, each tube 3 contracts due to its elasticity, is accommodated in a recess 5 in the inner wall surface 4, and is withdrawn from the flow path 2. Therefore, the flow rate of the flow path 2 can be increased.

き、制御することができる。 Inflating each rubber tube 3 by fluid pressure,
When protruding into the flow path 2, the amount of protrusion is determined by the magnitude of fluid pressure. The flow rate of the flow path 2 corresponds to the amount of protrusion of each rubber tube 3. Therefore, by adjusting the fluid pressure supplied to each rubber tube 3, the flow rate of the flow path 2 can be arbitrarily changed and controlled.

に支障をきたすことはない。 This flow control valve can decrease and increase the flow rate of the flow path 2 and control it by simply expanding and contracting the rubber tube 3, and there is no need to mechanically move the valve body as in the conventional valve. Therefore, problems such as friction and burning do not occur. Furthermore, it is not affected by impurities such as dust and does not interfere with flow rate control.

ものである。(f) Effects As explained above, according to this invention, a pair of rubber tubes 3 are installed in the valve casing 1 having a flow path 2 for fluid circulation, and each rubber tube 3 faces the flow path 2 in the diametrical direction. However, the rubber tube 3 is arranged not parallel to the flow path 2 but at right angles thereto. Each rubber tube 3 is accommodated in a recess 5 formed in the inner wall surface 4 of the flow path 2, and a fluid pressure supply source is connected to each rubber tube 3. moreover,
Each rubber tube 3 has an expansion amount corresponding to at least the radius of the channel 2. Therefore, when each rubber tube 3 is expanded by a fluid pressure source, each rubber tube 3 can be brought into contact over its entire length, and the flow path 2 can be completely closed. Moreover, when each rubber tube 3 is contracted, each rubber tube 3 is retracted into each recess 2 and the flow path 2 can be completely opened, and the rubber tube 3 does not affect the flow rate of the flow path 2. There is also no risk of turbulent flow in the flow path 2. Furthermore, the above-mentioned conventional problems such as friction and burning do not occur, and the intended purpose can be achieved without being affected by impurities such as dust.
