GENERAL CONCEPT The invention relates to one with a withdrawal valve

equipped tapping device for steam distribution networks.

THE STATE OF TECHNOLOGY

At the conventional draw-off points of steam distribution networks the nozzle valve and the electrical switching device of the valve are designed as separate structural units. Structural and operational disadvantages are associated with this design.

TASK

The invention is based on the object of a, Zapf device

for steam distribution networks to create «in which the nozzle

and its control device form a compact unit.

SOLUTION OF THE HUFGhBE

This gave up is erfindungsgemäQ been achieved in that the valve is connected via a sealed dispensing line to the steam system * The dispensing line can be of a cladding tube with i / ärmedämmstoff be enclosed, which is designed as l * empty square pipe i and thus for mounting bzui. structural union with the switching device for the nozzle. Furthermore, this design provides the advantageous possibility of designing the dispensing line to be uärmeenergiegeuußt by using /! Tapping pipe designed with a relatively large width of e.g. 3/4 "and with a welded-on male piece small Ueite for screwing

Connection with the valve connector of e.g. only 1/4 "connected is. The wide dispensing tube can be inserted into the surrounding polygonal tube be drawn in and thermally insulated by thermal insulation material in the cavity between the dispensing tube and cladding tube, preferably by using rock wool as a filler for the cavity between the tap pipe and cladding pipe. The cladding tube is suitable for assembly, especially in the case of a right-edged version a switch box on which an angled socket outlet is used to connect the electromagnetically operated nozzle may be appropriate. The nozzle itself is expediently designed to be adjustable.

This design results in a compact, clear, structurally and operationally simple tapping unit with low energy loss.

DESCRIPTION OF AN EXECUTIVE GAME

In the drawing, the invention is illustrated in an exemplary embodiment in a front view.

The dispensing device shown consists of a dispensing valve 2 which can be connected to the steam network 1 and has a consumer connection 15. There is a connection between the nozzle and the steam network from a wide nozzle 3 of e.g. 3/4 "diameter that can be connected to the steam network, for example by welding, on its free end a threaded piece 7 for a detachable screw connection is welded to the nozzle 2. The nozzle is provided with an actuator 4 through which * the The amount of steam can be adjusted. The wide. Dispensing tube 3 is enclosed by a cladding tube 5. This cladding tube is square formed, serves on the one hand for thermal insulation by taking up exEies thermal insulation material 6, preferably in the form of rock wool,

and on the other hand serves as a carrier for the assembly of a switch box of, for example, 80 χ 83 x 55 mm, with illuminated switch 11 and on Angled socket 10 attached to its side for connection to the electromagnetically operated nozzle 2 with solenoid I3 and E-connection 8,12.

Various modifications and other designs are still possible within the scope of the invention.
