Apparatus for cleaning a liquid connection, securing a stroke and spring abutment for double-seat pipeline switches with leakage control, comprising two valve disks of different sizes which are movable relative to each other and independently of each other, the smaller valve disk facing away from a drive rigidly connected via a valve rod with a pipeline switch drive and, upon its lift motion after a given partial stroke, positively carrying along with it the other, larger valve disk, the valve rods of the valve disks pointing in the same direction and engaging telescopically into each other with the end of the hollow valve rod which concentrically surrounds the other valve rod receiving, outside the pipeline switch housing, in a form fitting manner, a pressing and guide part, equipped with a lower stop surface and spring abutment, the valve disks both in the closed position and in the open position enclosing between themselves a leakage cavity which is connected via openings with a discharge bore leading into the atmosphere and arranged within the other valve rod a housing part, which receives an upper spring abutment, an upper stop surface, and a connecting opening for cleaning liquid forming in cooperation with the pressing and guide part, a spring chamber within which a spring is arranged, tightly closed off from the atmosphere.

Apparatus for cleaning a liquid connection and securing a stroke and spring abutment for double seat pipeline switches with leakage control, comprising a pipeline switch housing, a pipeline switch drive mounted within said switch housing, two valve disks of different sizes, two concentrically mounted valve rods of different lengths, one of said valve rods being hollow, the one of longer length fitting within the other of shorter length, said inside valve rod connected to said pipeline switch drive and the smaller of the two valve disks and defining a discharge bore leading to the atmosphere, said inside valve rod upon being lifted by said drive carrying along said valve disk of larger size, said valve disks in both the closed position and the open position enclosing between themselves a leakage cavity which is connected via openings with said discharge bore, a pressing and guide part fitting over an end of the hollow valve rod, a housing surrounding a portion of the longer valve rod and defining an upper spring abutment, an upper stop surface for said pressure and guide part and a connecting opening adapted to receive a cleaning fluid, said housing and said pressing and guide part together forming a spring chamber and a spring within said spring chamber tightly closed off from the atmosphere, said spring chamber communicating through said leakage chamber with said discharge bore to provide a fluid passageway for said cleaning fluid through said apparatus.
