- or control valve with a spherical ball a VeraohlußatUok

The .Sues ^ m ^ s. relates to a shut-off valve with a spherical or TereohlußstUok, in one führungsljÄfig untergebraoht iet »ä & T in the valve housing directly or through a supply piston vorgeeteuerten Actuate the transversely ~ aur Durohflußriohtung dea Bruckaittels.

Release or Moved closed position and in the closed position placed on a valve seat by the pressure medium In this case, the base piece slides or rolls on valve housing surfaces and about the valve seats that «loh especially when opening the valves as a result the Druotaaittelbelaetung cut into the Verachlußatüok and lead to damage to the sealing surface and leaks

innovation
The SWBäSKlöttg has the task of creating hatred »

the leadership of the Veraehlußstüekes on Ventilgehäuaefläohen and Venttlaitz make it easier and free of damage thereby make it possible for the ball to surface on the valve and valve housing via a passage opening in the guide cage unrollable in the guide cage let and that the isurohritta opening aindeetene to the in-opening arlohtung rear side through an inclined 3> opening axis outside edge is limited.

When moving the guide cage tilts the Beveled edge with a crosswise direction in the direction of movement Component of the pre-stroke force, which is used as the end piece Serving ball from the valve seat and causes the ball to move in the direction of the open division. Pie ball thus rolls over the valve edges, which Indentations in the spherical surfaces are prevented.

The circumferential arrangement is advantageous

Inclined edges tm of the passage opening _r so that the guide cage has an EoXl b »w in every row of movement of the Kfcgel. Tilting movement is granted and the actuation of the valve makes it possible to move freely and easily in both directions of movement. This means that the requirement for the use of flexible materials » z. B. Plastics or the like "for the iueblldung of kujfgel-shaped closure" given *

The Sohrägkante can be equally advantageously by bending of edge strips or by keilföraig auegeformte edges formed eeln whose sweeter Begrenzungeflachen obliquely aioh parallel and their inner Begrenaungeflachen aur movement Erich Tung dee Ptihrungskäfiga extend, the wedge shape of the bevel 1st thereby & o selected such that the ball with the inner Begrenaungaflache aur Effect comes and a cutting of the inclined edges in the breech block is excluded.

As a further development of the principle, in the case of valves with a ball that can be seated in both directions of flow in the valve, the guide cage can have two opposite passage openings for the ball, which are delimited circumferentially or partially by a beveled edge. In the valve 90 formed of Führtaigekäfig In ά & Ά both "buckle exerts pitches of the ball and a iushebekreft a tilting force on the ball, which to roll movements and a afcnutzungefreien

Handling dea valves leads.

Finally, the PUlirungskäfig is also planned at a distance from the Durohead openings with an additional XJflow channel to be provided for the pressure medium, which in the open position of the valve of the inlet and outlet opposite and offset in the closed position to the 2u and drain stands. The flow channel promotes tilt-free FÜJerung of the lead cage in the valve housing and be baw. The lCugel Kit relieves the pressure caused by the pressure medium to be applied pressure forces in the sense of faster closing or opening movements,

The connections 2 and 3 are connected to a central opening 4 in the valve housing, in which a veraobieblioher FUlirungskäfig 5 for a serving as a Versohlußstiick ball 6 is housed. The ball 6 is guided in the Puhrungskäfig free "movable and can it via passages openings 7» to cooperate with valve seats Θ and β ¹ laterally tiber protrude · In the closed position 6 of the Surohlaufrichtung of the pressure medium for closing the ice outlet is located, the ball according serving to echlussea to the Valve seat Θ or 8 'on · The movements of the guide cage 5 are made possible by a piston 9 »which is guided in a cylinder 10 firmly attached to the valve housing 1 through a lip seal 9 * and whose working chamber 11 is controlled by a magnetic auxiliary valve 12. The recess 4 is separated from the worker aura by further lip seals 11 ', which encompass the connecting piston rod 19 of piston 9 and puncturing cage 5. The tip diaphragms 11 are inserted in such a way that their lip edges are directed towards the recess 4 or the working space 11 *
