Description

DEUTSCHESGERMAN

Bei Niederdruck-Dampferzeugern mit einem Betriebsdruck bis zu 0,5 atü sind sogenannte »Standrohre« als Sicherheitseinrichtungen gebräuchlich, die keine Sicherheit dagegen geben, daß die Gewichtsbelastung unbefugterweise erhöht wird. Es wurde bereits versucht, diesem Mißstand dadurch zu begegnen, daß man die Belastungsgewichte kapselte und in den vom Dampf erfüllten Raum verlegte. Die Erfindung schlägt eine besonders einfache Lösung dafür vor, bei der das Neue darin besteht, daß das Belastungsgewicht als Pendelgewicht ausgestaltet ist, das den Ventilkegel auf seinen Sitz zieht.In the case of low-pressure steam generators with an operating pressure of up to 0.5 atü, so-called "standpipes" are required commonly used as safety devices which do not provide any security against the fact that the weight load is increased in an unauthorized manner. It was already tried to counteract this deficiency by encapsulating the loading weights and moved to the steam-filled room. The invention proposes a particularly simple solution for which the novelty consists in the fact that the loading weight is designed as a pendulum weight, that pulls the valve cone onto its seat.

An Hand der Zeichnung sei die Ausgestaltung des vorgeschlagenen Sicherheitsventils als Ausführungsbeispiel erläutert. *5 The design of the proposed safety valve is explained as an exemplary embodiment using the drawing. * 5

Das Ventil ist mit einer Verschraubung 2, dem vorzugsweise kugelförmigen Ventilteller 3 und dem Ventilsitz 4 versehen. Der Ventilteller 3, der, wie gestrichelt angedeutet, bei Fortfall der Verschraubung 2 auch als Vollkugel ausgestaltet sein kann, ist erfindungsgemäß mit einem Pendelgewicht 7 über die Stange 9 verbunden. Das Pendelgewicht 7 besitzt einen tief liegenden Schwerpunkt und arbeitet, wie leicht ersichtlich, in dem mit den Reduziernippeln 5 und 6 versehenen Gehäuse 8, das oberhalb des Reduziernippels 5 ein T-Stück 1 mit seitlich angeordnetem Rohrstutzen zum Anschluß an den Wassersack besitzt. Das T-Stück 1 ist durch eine deckelartige Verschraubung 10 verschlossen.The valve is with a screw connection 2, the preferably spherical valve plate 3 and the Valve seat 4 provided. The valve disk 3, which, as indicated by dashed lines, if the screw connection 2 is omitted can also be designed as a solid ball, is according to the invention with a pendulum weight 7 on the Rod 9 connected. The pendulum weight 7 has a low center of gravity and works like easily seen in the housing 8 provided with the reducing nipples 5 and 6, which is above the reducing nipple 5 has a T-piece 1 with a laterally arranged pipe socket for connection to the water bag. The T-piece 1 is closed by a cover-like screw connection 10.

Es ist klar, daß der Betriebsdruck durch das entsprechend bemessene Gewicht 7 stets unveränderlich ist und eine Verstellung durch Unbefugte sowohl bei der Ausführung mit Gehäuse als auch bei unmittelbar Sicherheitsventil, insbesondere
für Niederdruck-Dampferzeuger
It is clear that the operating pressure is always unchangeable due to the correspondingly dimensioned weight 7 and an adjustment by unauthorized persons, both in the case of the version with a housing and in the case of a direct safety valve, in particular
for low pressure steam generators
