Description
DEUTSCHESGERMAN
Gegenstand des Hauptpatentes 954 290 ist eine Druck- und Temperatursicherung für Heißwasserdruckspeicher, die sowohl auf einen unzulässig hohen Druck im Speicher als auch auf eine unzulässig hohe Temperatur des Speicherinhaltes anspricht. Diese Sicherung besteht aus einer Reißscheibe, die mittels einer bei 95 bis 100° C schmelzenden Lötmasse in eine Sicherungspatrone eingelötet ist. Überschreitet die Temperatur des Speicherinhaltes den zulässigen Wert, so schmilzt diese Lötmasse, und die Reiß scheibe wird vom Betriebsdruck des Speicherinhaltes aus der Sicherungspatrone herausgedrückt und gibt den Speicherinhalt frei. Steigt der Druck im Speicher auf einen unzulässig hohen Wert, dann reißt die Reißscheibe auf, und der Druck im Speicher sinkt unter den zulässigen Höchstwert.The subject of the main patent 954 290 is a pressure and temperature fuse for hot water pressure accumulators, both to an impermissibly high pressure in the accumulator and an impermissibly high one Temperature of the memory content responds. This fuse consists of a tear disk, which by means of a soldering compound that melts at 95 to 100 ° C is soldered into a fuse cartridge. Exceeds If the temperature of the memory contents exceeds the permissible value, this soldering compound melts and the tear disk is pressed out of the fuse cartridge by the operating pressure of the memory contents and releases the memory contents free. If the pressure in the accumulator rises to an impermissibly high value, the tear disk will tear and the pressure in the storage tank drops below the maximum permissible value.
Im Zusatzpatent 963 018 ist anstatt der Reißscheibe eine konkav gewölbte Berstscheibe vorgesehen, die bei Überdruck in die Konvexlage umschlägt und die Weichlotnaht aufreißt. Da die mechanische Festigkeit der Lötmasse bei höherer Temperatur absinkt, spricht die Sicherungsscheibe nicht bei einer ganz bestimmten Temperatur und auch nicht bei einem ganz bestimmten Überdruck an. Die Ansprechwerts streuen. Um die Streuung der Temperatur- und Druckwerte zu verringern, wird die Berstscheibe erfindungsgemäß zwischen zwei Formstücke eingelegt, die mit einem Weichlot verlötet sind, derart, daß das Weichlot bei Druckbelastung der Berstscheibe nur gering beansprucht wird und die auf der Berstscheibe ruhende Druckbelastung bis unmittelbar vor dem Schmelzpunkt aushält.In the additional patent 963 018, instead of the tear disk, a concave rupture disk is provided which is used in Overpressure turns into the convex layer and the soft solder seam tears. Because the mechanical strength If the soldering mass drops at a higher temperature, the locking washer does not speak at a very specific one Temperature and not even at a certain overpressure. Scatter the pickup values. To the To reduce the spread of the temperature and pressure values, the rupture disc according to the invention is between two fittings inserted, which are soldered with a soft solder, in such a way that the soft solder at The pressure load on the rupture disc is only slightly stressed and that resting on the rupture disc Withstands pressure up to just before the melting point.
Dadurch, daß die Berstscheibe zwischen die zwei Formstücke eingelegt und nicht selbst mit den Focmstücken verlötet ist, unterliegt die Lötverbindung nicht den Biegespannungen der Berstscheibe. Vorzugsweise wird die Lötverbindung, die die beiden Formstücke zusammenhält, so angeordnet, daß sie auf Abscherung beansprucht wird.Because the rupture disc is inserted between the two shaped pieces and not itself with the focm pieces is soldered, the soldered connection is not subject to the bending stresses of the bursting disc. Preferably the solder joint that holds the two fittings together is arranged so that it shears off is claimed.
Abb. 1 zeigt einen Schnitt durch die gefaßte Druck- und Temperatursicherung. Träger der Berstscheibe ist der Fassungsring α mit einer Dichtung b, welche die ganze Sicherungspatrone gegen den zu sichernden Behälter abdichtet. Die konkav gewölbte Berstscheibe c wird durch einen. Paßring d gehalten, der mit einem Weichlote mit dem Fassungsring α verlötet ist. Sobald die Schmelztemperatur des Weichlotes erreicht ist, wird die Scheibe c mit dem Paßring d durch den auf der Scheibe lastenden Druck aus ihrer Fassung gedrückt. Damit wird der zu schützende Behälter entspannt, weil das Medium durch die entstandene öffnung austreten kann.Fig. 1 shows a section through the mounted pressure and temperature fuse. The carrier of the rupture disc is the mounting ring α with a seal b, which seals the entire fuse cartridge against the container to be secured. The concave rupture disc c is by a. Fitting ring d held, which is soldered with a soft solder to the mounting ring α. As soon as the melting temperature of the soft solder is reached, the disc c with the fitting ring d is pressed out of its socket by the pressure on the disc. This relieves pressure on the container to be protected because the medium can escape through the opening that has been created.

Weichlotes noch nicht erreicht ist. Nach dem Hauptpatent 954 29O1 ist die Scheibe vorgestanzt, aber nicht durchgestanzt, so daß sie bei Überdruck an der vorbestimmten Stelle aufreißt. Nach dem Zusatzpatent 963 018 ist die Berstscheibe konkav gewölbt, so daß sie bei Überdruck in ihre andere Totlage durchschlägt und an der Lötnaht abreißt. Nach der vorliegenden Weiterentwicklung ist die Berstscheibe c tellerförmig gestaltet und nach Abb. 2 am Rand / scharf ausgestanzt. Sobald der auf der Scheibe ruhende Druck die Sicherungsgrenze überschreitet, schlägt die gewölbte Scheibe c in ihre andere Totlage um und reißt an dem scharfkantig gestanzten Rand / ab und gibt wie bei Übertemperatur die ganze Öffnung frei.Soft solder has not yet been reached. According to the main patent 954 29O 1 , the disc is pre-punched, but not punched through, so that it tears open at the predetermined point when there is excess pressure. According to the additional patent 963 018, the rupture disc is concave so that when there is overpressure it penetrates into its other dead position and tears off at the soldered seam. According to the present further development, the bursting disc c is designed in the shape of a plate and is punched out sharply at the edge / as shown in Fig. 2. As soon as the pressure resting on the disk exceeds the safety limit, the curved disk c flips over into its other dead position and tears off at the sharp-edged punched edge / and releases the entire opening as if it were overheating.
TJm für den Überdruck ein Höchstmaß an Sicherheit zu erhalten, ist nach Abb. 3 und 4 eine scharfe Spitze g vorgesehen, auf die die Berstscheibe beim Durchschlagen aufschlägt und durchstochen wird. Für den Fall, daß beim Durchschlagen die Scheibe c am Rand / nicht abreißen sollte, wird mit dem Durchstich der Spitze g eine immer noch ausreichende Öffnung frei, durch die das Medium des Behälters austreten kann. In bekannter Weise kann an die Ableitung von dem ausströmenden Medium eine optische oder akustische Signalanlage angeschlossen werden. Abb. 3 und 4 zeigen die Anordnung der Spitze g auf ihren Träger h.TJm to obtain the highest level of safety for the overpressure, a sharp point g is provided according to Figs. 3 and 4, on which the bursting disc hits and is pierced when it hits through. In the event that the disc c should not tear off at the edge / when it is pierced, the piercing of the tip g frees an opening which is still sufficient through which the medium of the container can exit. In a known manner, an optical or acoustic signal system can be connected to the discharge of the outflowing medium. Fig. 3 and 4 show the arrangement of the tip g on its support h.
