Throttle valves or as they are called still, butterfly valves, are used for regulation of amount of the air passing on air ducts and for prevention of an overflowing of air at the switched - off fan. A throttle valves like DKK and DKP intend for use in nonaggressive and inexplosive air - gas streams.
Throttle valves in usual execution are used in ventistema with working pressure up to 1500 Pas, at the content of dust and other impurity in air no more than 100 mg/m3. It is optimum to use a throttle valve at design and installation vensisty in which aggression of the moved air - gas mix is comparable with properties of usual air with a temperature up to 80 of 0C. Installation a throttle valve on horizontal or on the vertical site of an air duct is possible (if the stream of air is directed from below up).
The design a throttle valve includes the steel case of round or rectangular section and the shovel located in the case. Sideways the throttle valve has knot of management of position of a shovel. The management sector a throttle valve gathers at installation and is welded on the case and a shovel.
To regulate position of a shovel it is regulated by means of the manual drive.
When make adjustment of pressure in ventilating system, establish a throttle valve in the certain fixed situation. In a limit closed position the throttle valve passes through itself only 10 - 12 from all consumption of air in an air duct.
