elastic sealing rings.

Machined, perpendicular to the direction of flow and. flat housing surfaces arranged in parallel, the inner circular ones Passages are expediently the same or at most slightly larger than the line diameter, so that the flow course is not disturbed, are used according to the invention in the Dismantling or dismantling of the ball plug facing the valve body Circular ring surfaces of the seat rings as guides and the elastic sealing rings also in operation as - "Wic & bearings.

To prevent canting of the seat rings when the ball plug is switched according to the frictional forces between the ball plug and the sealing ring should be avoided on the housing surfaces described above further housing surfaces arranged vertically, provided, the vertical from the housing center plane up and down are directed and in the horizontal housing center plane on both sides the seat rings have line contact with the seat rings, so that one or the other housing line, depending on the switching direction the frictional forces on the ball plug on the inlet and outlet of the tap can accommodate.

In the course of further simplification of the cock construction can still of the known designs for closing the cylindrical inlet side for the ball plug (neck side) Main shaft (cover, multi-part insert ring; cover retaining piatie and Screws for bracing the aforementioned parts) the ceiling retainer plate and the screws are inserted.

Bearing pin on the bottom of the ball plug presses over the ball plug and a circular ring disk that acts like a thrust bearing, tied together.

The invention is explained in more detail with reference to the drawing using an exemplary embodiment. It shows; Pig. 1: Section I - I of Pig. 2, ball plug in closed position

Pig. 2: Section II - II of the pig. 1, ball plug turned to the through position and Pig. 3 ·: Section IXI - III of the Pig. 1, ball plug omitted.

The tap housing 1 has the base 2, the PIaIs 3 and the ear pieces 4 and 5, each of which can be provided with one of the known detachable or non-detachable pipe connection elements. The ball plug 6 carries the bearing pins 7 and 8 and following the bearing pin 8 the square 9 for the actuation of the ball plug The torque required for switching the ball plug 6 can be applied to the square 9 in a known manner by a key by hand or mechanically, for example be transmitted by an electric motor, via appropriate transmission gears. Hit 10 and 11 are bearings for the bearing pins 7 and ^8: for example, plastic bearings, 12 and 13 are seals for sealing the bearing pin 7 and 8 relative to the housing 1 or, "the cover 18 and over the bearings 10 and 11, for example 0 -liinge, respectively. the gasket 14, for example an O-inputs, serves to seal the bearing 11 to the outside. the Einstellsehraube 15, for example a screw with hexagon socket or a slot, presses against the bearing pin 7, the ball plug 6, and as a Circular ring disk 371 acting on a thrust bearing, for example made of plastic, on the cover 18, which is thereby permanently clamped together with the multi-part insert ring 19 in the tap housing 1 even when the valve is depressurized.

The .'rretierungs- and housing ventilation screw 23 prevents rotation of the cover 18 while retaining the ball plug 6 and is used to vent the valve body 1, while the seal 24 the screw 23 opposite the valve body

The seat rings 25 and 26, which are formed tils bodies of revolution the sealing rings 27 and 28, which act as a seal against » cause over the ball plug 6 and can be made of plastic or another suitable material. With 29 and 30 are elastic Sealing rings, for example O-rings, are used in the hats 35 and 34 of the valve body 1 are housed or in the Seat rings 25 and 26 can be located, the seat rings 25 and 26 seal against the valve body 1 and because of their deformability represent prestressing elements under the pressure of the pipe medium, ' which, depending on the variable line pressure, has a variable preload on the seat rings 25 and 26, whereby the pretension of the sealing rings 27 and 28 on the ball plug 6 are given. The pressures created by the Pressures of the conduction mediura on the effective circular surfaces of the Seat rings - between seat ring inner diameters and elastic ones Sealing rings 29 and 30 - result and appear as the sum of both the overall sealing pressures of the sealing rings 27 and 28 to the Ball plug 6.

The processed housing surfaces 35 and 36 on the G-stehen'senkrecht ehäuseflächen 31 and 32 form in their whole lengths of parts of the outer boundaries of the G-ehäuseflächen 31 and 32 are therefore parallel to the flow direction, going from the bottom side of the housing faucet t 1 as eccentrically arranged half-cylinder surfaces, whose eccentricities c point parallel to the ball plug axis in the direction of the bottom 2 and merge on both sides of the half-cylinder into parallel flat strip surfaces that begin in the horizontal plane through the eccentric centers - directed vertically through the horizontal center plane of the Penetrate valve body 1 and end in the upper half of valve body 1, with the diameter of the inner half cylinder and the distances between the parallel strip surfaces of each pair of strip surfaces are equal to the outer diameters of the seat rings 25 and 26, so that the outer cylinder surfaces of the seat rings 25 and 26 with the parallel stripes on the S stretch e, f, g and h in the horizontal middle ele have line contact. Along the sections e, f, g and h - depending on the switching direction of the ball plug 6 - there are always two sections of abutments for the seat rings 25 and 26 during the peeling process, taking the frictional forces on the circumference between the ball plug 6 and the sealing ring en 27 and 28 and thus prevent the seat rings 25 and 26 from tilting.
