"Pressure reducing valve, especially for compressed air lines with a safety device »»

The! Inflation relates to a pressure reducing valve, a safety device is provided in its housing. The valve is to be used in particular for compressed air lines «

With valves of this type, the Bleder pressure side (secondary side) must be vented * if you want to pass a lower bridge on this low pressure side ZXi than was initially set, Kieses Intlüften means special handling of a corresponding vent valve,

tlm the working surfaces of such a valve za rereinf which Feuerung'Torgesehlagen, the spring-loaded and the pressure reducing valve influencing membrane vegetables m additionally control a vent. can .. This is automatically achieved an S & tlufte & ^ because in mak- ing any changes of the leather-voltage for the Bruekrainderung SU6a> Öiö loading of these Sicherheitseinriöktung Terri Gert is such that _r ier 6berdruck aer after reduction of the pressure is still present on ier Hiederdruckseite can escape, Q ne that a particular Vejitil is actuated.

In the practical version, the valve spindle is with a valve seat for the one having a through-opening Membrane and provided with a Büekdruckfeäer. Fenn the

Pressure of the DiHKik reducing valve by changing the spring tension is changed, the pressure on the low pressure side lifts the Diaphragm from the valve seat of the valve spindle, and the Air that still has excess pressure can escape.

On the drawing is an execution example of one Pressure reducing valve according to the innovation shown in section.

The Sehäuse 1 · provided for example with öewindeansätzen 2 and 3 for the Druekluftleitung In iruasrL · is the valve spindle 4, which Seiler 5, the seal 6 supports · The valve "spindle is carried out upwardly and sealed by a sleeve 7,

Semäs "the hiring this valve spindle receives a special valve seat 8, which lies against the membrane 9" Loads is this membrane in the usual way by a spring 1o, the pressure of which is adjustable by means of the pressure screw 11 · The The spring is in the locke 12 »in the middle of the membrane a passage opening 13 is arranged · The bell 12 receives also several passage openings 14 »

The function of the valve is as follows. With the help of the screw 11, the valve is adjusted to a certain position. Di ¹ UOk set y ep that this pressure prevails on the I low pressure side. Should now. on this page CFER bridge lowered i "ground, so the spring is 1o corresponding relaxed · Here henraekt initially to aer Kiederdruekseite he £ even higher pressure that lifts the diaphragm from the seat 8 _r so that the excess pressure through the bore and the Escher 14 can escape to the outside *

So that the valve spindle 14 is pressed again against the diaphragm 9 when the pressure is reduced, an additional pressure relief device 15 is provided below the valve disk 5.

Claims (1)

In this way Maa receives a very simple pressure reducing valve, in which automatically an overpressure from the secondary side through, the same valve can escape. Protection claims? . ■% Bruokminder valve »especially for air ducts with a safety device, characterized * that the spring loaded membrane (9) influencing the valve also controls a ventilation opening (13)» 2, valve according to article 1, characterized by »that the . ■ a TentilspindeJL (4) with a valve seat (S) for the / passage opening (15) having membrane (9) and with a pressure spring (15) is provided »
