Definitions
- the present invention relates to a handle with a torque limiter and a fluid controller provided with the handle.
- the handle with torque limiter can prevent excessive torque from being applied, and the valve body is over-tightened by always performing constant opening and closing operation when opening and closing the fluid controller.
- the present invention relates to a fluid controller provided with a handle with a torque limiter that can prevent deformation due to fluid flow and can perform stable flow control over a long period of time with less wear and damage to the valve body even after repeated use. Background art

- the diaphragm (B) is usually made of a soft rubber material excellent in corrosion resistance and flexibility in order to be always in contact with the fluid! ing. Therefore, since the soft rubber material opens and closes the flow path (A-1), it does not give much resistance to the flow of the fluid and the sealing performance is excellent, and the fluid does not leak. It was a fluid controller with excellent features for blocking chemicals such as acids, for example, without the risk of corrosion.
- the conventional diaphragm valve (Z) which has the above-mentioned structural force while being forced, causes damage to the diaphragm (B) at the time of closing the flow passage (A-1), and immediately uses it repeatedly for long periods of time. As a result, the deterioration and fatigue of diaphragms became remarkable, and for many years, stable flow control could not be performed!
- the operating mechanism (D) is moved downward by turning the handle (E) to press the diaphragm (B) against the predetermined contact portion (A-2). Therefore, the force by which the flow path (A-1) is closed is excessive on the soft rubber material diaphragm (B), where the tightening of the handle (E) at the time of the flow path closing is often stronger than necessary. Because of the load, it is easy to cause damage and wear along with repeated use for many years, and can not perform stable flow control over a long period of time.
- the opening and closing operation of the flow path by the diaphragm can always be performed with a constant clamping force, and even after repeated use, the diaphragm has been stable over a long period of time with less wear and damage. It was an extremely good technology that enabled flow control.
