    • High-power transmitter valves are located in a housing through which a fan feeds a cooling air stream between an inlet point and an outlet point, the inlet air temperature being required to lie within a range set by the valve manufacturer. The device according to the invention, which is located outdoors, comprises a first duct connected to the inlet point of said housing and a second duct connected to the outlet point thereof. Both the first and second ducts are connected to the outside atmosphere, the first by way of a filter and the second by way of a throttle valve which enables a fraction of the air flowing through the second duct to be recycled to the first duct upstream of the filter, and which for this purpose is controlled by a temperature transducer located in the first duct downstream of filter.
    • 大功率变送器阀位于壳体中,风扇通过该壳体在入口点和出口点之间供给冷却空气流,入口空气温度需要位于由阀门制造商设定的范围内。 位于室外的根据本发明的装置包括连接到所述壳体的入口点的第一管道和连接到其出口点的第二管道。 第一和第二管道都连接到外部大气,第一管道通过过滤器连接,第二管道通过节流阀连接,使得能够将流过第二管道的空气的一部分再循环到第一管道上游的第一管道 过滤器,并且为此目的由位于过滤器下游的第一管道内的温度传感器控制。
