[0055] As shown in the figure, the fluid controller (1) of the present invention includes a valve cover (2) having a fluid channel therein, a valve membrane (3) for opening or closing the fluid channel (21), a contraction element for fixing the periphery of the valve membrane (3) between said valve housing (2) and said constriction element (4), an operating device (5) with a connection to said valve membrane ( 3), and a handle element (6) for vertically moving the operating device (5).

[0056] In the shown embodiment, the fluid controller according to the invention is shown as a diaphragm valve, the diaphragm (3) of which is constituted by a diaphragm. Therefore, in the following description, the valve membrane (3) is explained as a diaphragm (3).

[0057] But the present invention can be applied not only to diaphragm valves, but to any fluid controller that may be deformed / damaged due to excessive tension. Such fluid controllers may be flap valves, needle valves, plug valv...

Abstract

The invention provides a handle equipped with a torque limiter capable of preventing application of excessive torque, and a fluid controller provided with the same. An elastic body (7) has a minimum urging force capable of developing a function desired when the handle is lowered to the lowest position. Disposed in the handle are a transmitting member (8) urged by the elastic body and a transmitted material (10) against which the lower surface of the transmitting material is pressed. The surface of the transmitted material opposed to the transmitting material or the surface of the transmitting material opposed to the transmitted material is formed with serrations along the periphery having inclined surfaces (81, 101) and vertical surfaces (82, 102) which alternately appear. The inclined surfaces of the serrations are upwardly tapered along the direction of rotation in which the cover body descends.

Description

technical field [0001] The present invention relates to a handle with a torque limiter and a fluid controller with the handle. In particular, the invention relates to a handle characterized by a torque limiting function capable of preventing excessive torque from acting on the diaphragm. The invention also relates to a fluid control having the handle which is opened or closed by a constant clamping force. Therefore, the fluid controller does not deform the valve diaphragm due to overtightening during the closing operation. This causes less damage or wear to the valve diaphragm, so the fluid controller will provide stable flow rate control over extended periods of time. Background technique [0002] Diaphragm valves are commonly used in chemical industry plants for fluid flow control handling corrosive fluids or high purity fluids. [0003] for example, Figure 19 Shows a diaphragm valve comprising a valve housing (A) with a fluid passage (A-1), a diaphragm (B) in contact ...
