Electrically controlled actuating device incorporating a thermostatic function, and valve |
摘要 |
A actuating device includes a fixed portion forming a frame including an inlet intended to receive a fluid, a main outlet and a sampling outlet and a return device for exerting a mechanical force on a movable portion; a movable portion including a shutter moving between an open position and a closed position; a thermostatic device including a conical turning disc, the turning of the disc above a known critical temperature driving the shutter to the closed position of same; a control device allowing a holding force for holding the shutter to be generated, the control device being able to be controlled in such a way that below the critical temperature, the opening or the closing of the valve results from the balance between the holding force and the mechanical force. |

1. An actuating device, comprising:
a fixed portion forming a frame comprising an inlet intended to receive a fluid, a main outlet and a second outlet, and a return device; a movable portion, wherein the return device is configured to exert a mechanical force on the movable portion, the movable portion comprising:
a shutter comprising a rod moving in translation between an open position of the second outlet and a closed position of said second outlet under the effect of the mechanical force; a thermostatic device comprising a conical turning disc integral with a collar movable around the rod of the shutter, the turning of the disc above a known critical temperature driving the shutter to the closed position of same; a control device allowing a holding force for holding the shutter to be generated, the control device being able to be controlled in such a way that below the critical temperature, the opening or the closing of the shutter results from the balance of forces between the holding force and the mechanical force. |
