"Pre-settable heating valve with stony spindle"

The innovation concerns a heating valve that can be preset from the outside with rising spindle

Most heating valves have a non-rising stem. Heating valves with a rising stem are one Simplified construction, the spindle of which moves up and down with the handle when opening and closing the valve emotional. This design has the advantage that it is less sensitive to shock and impact loads at high water pressure is through the water and therefore there is no sound.

The new feature is intended to solve the task, the default setting to be determined, i.e. to fix the largest opening of the valve with a stop.

As a novelty, it is proposed that the valve with a threaded upper part when opening and closing to provide miinhmbaren threaded ring and an adjusting ring inserted in a groove.

In a further development of the innovation, the threaded ring can be carried along by a cap covering the upper part.

It also belongs to the innovation k the threaded ring outside as To form a polygon and to provide the cap with a corresponding recess that grips the threaded ring »

According to the innovation, a snap ring is used as the limit stop.

In the drawing, an embodiment of the heating valve is shown according to the innovation.
It shows:
1 shows a vertical section through the valve;

Figo 2 shows a horizontal section through the upper part along the line A-A.

In the lower part 1 of the valve, which is provided with two connecting pieces 2, there is the closing body 3 of the valve, which is operated by the spindle 4. The spindle 4 is for upward and downward movement with a handle 5 and thread 6 provided which engages in a nut thread in the upper part 7 of the valve. i) The upper part 7 contains the stuffing box g. with the stuffing box nut 9

The upper part 7 is provided on the outside with a further thread 1o, onto which a threaded ring 11 is screwed. This threaded ring 11 is octagonal on the outside and is supported by the cap-shaped

tig trained, provided with an octagonal recess handle 5 detected, which is useful with two opposite Metal inserts 12 is provided. A snap ring 13 is inserted into the thread 1o, up to which the threaded ring 11 rises | gen can «

The presetting is done simply by removing the cap-like Handle 5 and by inserting the snap ring 13 at the desired height before starting the heater. When the cap-like handle 5 is screwed tight, the default setting is established.
