Valve

The innovation relates to a valve, in particular for use as a filling and draining valve for pipeline systems, primarily heating systems, consisting of a housing with a Connection stub and a valve seat, preferably with a conical Sealing surface, as well as a closure body which is axially adjustable in the housing and which is tubular in connection with the sealing surface is formed and the at least one of the valve seat at least indirectly closable and in the tubular part the closure body has opening opening.

A known valve of this type has a tubular body as an actuator, one end part of which is rotatable with the closure body and is connected in an axially immovable manner and the other end part of which is mounted on the housing in an axially limited screwable manner.

However, there is the disadvantage that this solution is material and is very expensive to manufacture. In addition, the handling of opening and closing the valve is not clear recognizable from the outside.

The task of the innovation is now to provide a valve as described at the beginning To improve and simplify the genus both in terms of its manufacturing options and in terms of its operability.

The solution to this problem is characterized according to the innovation by an actuator that is tubular. the Closure body is fixedly connected to this in the direction of rotation and loosely displaceable in the axial direction. Through this Measure there are only two instead of three operating elements required to operate the valve, which in their Puncture are clearly visible. The design is also much more compact than comparable solutions.

An embodiment of the above-described one which is advantageous in terms of production technology The object is that the loose connection between the actuator ^ and the closure body of this to the Actuator facing end part is designed as a polygon and the actuator has a corresponding guide. An advantageous embodiment of the above-described object is that the closure body is attached to that of the actuator remote end part is connected by an external thread with an internal thread zone of the housing.

Another embodiment of the above-described one which is advantageous in terms of production technology The object is that to connect the housing and the actuator in these opposite one another Grooves that are open to one another and extend in the circumferential direction are arranged are, in which a snap ring is arranged.

An embodiment of the innovation is shown in the drawing - nr \ A is described in more detail below. Show it

Fig. 1 shows a valve in longitudinal section, each half in the Closed or open position,

Fig. 2 is the same in the front view.

This valve, which is used in heating systems, for example in radiators as a filling and draining valve, consists of a housing with a threaded connector 2, a zone 3 with closing surfaces and a conical conical section arranged coaxially with the connector 2

-V- Ci

Valve seat 4 as well as one in the housing 1 coaxial with the connector 2 adjustable and rotatably mounted closure body 5 with sealing surfaces 6 designed to conform to the valve seat 4- an actuator 7 loosely connected to the closure body 5 by a hexagon 12

On the outer adjusting ring 8 of the adjusting element 7 there are two wrench surfaces 9 and a connecting piece 10 having an external thread molded.

Not far from the sealing surface 6 are two diametrically arranged to one another Breakthroughs 11 are provided.

As a connecting element between actuator 7 and housing 1 a snap ring 13 is provided, which is in annular grooves of the housing and the actuator 7 engages.

The middle part of the closure body aimed at the nozzle 2 has an external thread which is screwed into an internal thread zone 14 arranged on the housing 1.

In a further annular groove of the housing 1 is a with the cylindrical Inner wall of the actuator 7 corresponding O-ring arranged.

On the connecting piece 10 can optionally be a closure cap 16 or a Union nut 17 for connecting a hose connector 18 can be screwed on.

The closure cap 16 is captively attached to the actuator 7 by means of a chain 19.

The connector 18 engages with a conically tapered end part 20 tightly into a conformal extension of the actuator 7. He has an annular groove which receives an O-ring 21 corresponding to the cylindrical inner wall of the actuator 7.
