Driven proportional-control thermostatic device with back-up thermostatic element |
摘要 |
The invention relates to a valve-type device including a housing having a fluid access (7) which is shut off by a shutter (9) secured to an actuator (10) as a function of the temperature of the fluid passing through the device. The device also includes an expanding-material safety thermostatic element (22) located in the stream of fluid passing through the housing. The element 22 actuates the shutter (9) when, as a result of defective operation of the actuator (10) or of its control equipment, the shutter has not been moved by the actuator. The actuator also consists of an expanding-material thermostatic element containing a heating means (13) connected to control equipment.
