Definitions
- the invention relates to a ball valve, in particular a three-way ball valve, with a housing which receives an essentially spherical valve body and in which a passage, in particular a straight line, is provided between two in particular coaxially arranged connections, which is open in a first position of the valve body and in a second Position of the valve body is closed.
- Ball valves are used, for example, in water supply line systems to specifically interrupt the flow through certain line sections. For reasons of frost protection, it may be necessary, for example, to drain a section of the line that is separate from the water supply.
- a separate drain valve can be provided in addition to the ball valve. The separate drain valve is closed when the ball valve is open. If the flow through the ball valve is interrupted, the drain valve can be opened to drain the associated line section. After emptying, the emptying valve can be closed again to prevent dirt or bacteria from the environment from getting into the emptied line section.
- the manufacture of a ball valve with an additional drain valve is complex and expensive.
- the object of the invention is therefore to provide a ball valve of the type described at the outset with an emptying function, which is simple and inexpensive to produce.
- the object is achieved by a ball valve which has the features of patent claim 1.
- the ball valve is preferably designed as a three-way ball valve.
- An essentially spherical valve body is accommodated in a housing, which can be made in one or more parts.
- a passage is provided in the housing and runs in a straight line between two coaxially arranged connections from the input side to the output side of the housing.
- the valve body is rotatably received in the housing and can assume at least three different, defined positions. In the first position of the valve body, the passage through the housing is open. In the second position of the valve body, the passage is closed.
- the passage on the inlet side is closed.
- the outlet side of the passage is connected to the third position of the valve body with an emptying opening which is provided on the housing.
- a ball valve in the form of a 3/3-way valve with an integrated drain valve is therefore created.
- a preferred exemplary embodiment of the ball valve is characterized in that the valve body has a through hole from which a drainage channel emerges, which is closed in particular by the housing in the second position of the valve body, and which is connected to the drainage opening in the third position of the valve body ,
- the arrangement of the drainage channel in the valve body provides the advantage that the valve body needs to be equipped with only one actuating element, with the aid of which the valve body can be brought into the three different positions, in particular rotated.
- Another preferred exemplary embodiment of the ball valve is characterized in that the drainage channel is a smaller one Cross section has as the through hole in the valve body. Since generally only a limited volume has to be emptied, the emptying channel can have a significantly smaller cross section than the through hole.
- the drainage channel is arranged essentially transversely to the through hole in the valve body. This ensures that the drainage channel opens into an annular space between the valve body and the housing.
- the annulus represents a dead water area in which bacteria and / or pathogens can collect under certain circumstances.
- water can escape through the emptying channel opening into this dead water area.
- fresh water can also reach the dead water area through the drainage channel when the valve body is in the first position. This ensures good mixing of the liquid accumulating in the dead water area.
- the drainage channel is used to ventilate the annular space when the valve body is in the third position.
- valve body has the shape of a ball with a through-hole in the form of a cylindrical cylinder.
- This configuration of the valve body has the advantage that it is easy to implement in terms of production technology.
- Another preferred exemplary embodiment of the ball valve is characterized in that the relief channel is designed as a through hole. This further reduces manufacturing costs.
- Another preferred exemplary embodiment of the ball valve is characterized in that the drainage channel is based on the through hole is arranged centrally in the valve body. This ensures the greatest possible strength and stability of the valve body.
- Another preferred exemplary embodiment of the ball valve is characterized in that the drain opening is arranged in the housing in the vicinity of the passage. This leads to a simple design of the housing and to short adjustment paths for the valve body.
- Another preferred exemplary embodiment of the ball valve is characterized in that an in particular annular seal is arranged in the region of the drain opening between the housing and the valve body. The seal prevents water from getting into the gap between the housing and the valve body.
- Another preferred exemplary embodiment of the ball valve is characterized in that an actuating element is attached to the valve body, with which the valve body can be adjusted to the three positions. This greatly simplifies the operation of the ball valve.
- FIG. 1 shows a highly simplified, schematic illustration of a ball valve with a valve body in a first, open position
- Figure 2 shows the ball valve of Figure 1 in a second, closed position
- Figure 3 shows the ball valve from Figures 1 and 2 in a third, so-called emptying position
- Figure 4 shows an embodiment of a ball valve in side view
- Figure 5 is a sectional view taken along the line V-V in Figure
- a ball valve is greatly simplified, shown schematically.
- the inlet side of the ball valve is labeled E and the outlet side is labeled A.
- the input side E and the output side A are preferably designed as connections, for example for further line elements.
- the ball valve comprises a valve body 1, which has the shape of a ball.
- a central passage 2 is provided in the spherical valve body 1.
- the passage 2 has the shape of a circular cylinder jacket and can be produced by drilling.
- an emptying channel 3 extends from the center of the passage 2 and runs in the radial direction.
- the direction of flow through the valve body 1 is indicated by an arrow 4.
- the valve body 1 is arranged between two ring seals 5 and 6.
- the ring seals 5 and 6 are in a known manner on (not shown) housing parts.
- the inner diameter of the ring seals 5 and 6 corresponds to the diameter of the passage 2.
- the ring seals 5 and 6 create a seal between the valve body 1 and the housing.
- valve body 1 is in contact with an annular seal 8, the inner diameter 9 of which corresponds to the diameter of an emptying passage (not shown).
- the drain passage is formed in the housing and serves to drain the outlet side of the ball valve, while the inlet side of the ball valve is closed.
- the valve body is in a first position in which the inlet side E is connected to the outlet side A of the ball valve via the passage 2.
- the passage 2 is connected via the drainage channel 3 to a dead water area T, which can be designed in the form of an annular space outside the valve body 1 and inside the housing (not shown).
- valve body 1 In Figure 2, the valve body 1 is shown in its second, closed position. In this position, the inlet side E of the ball valve is closed by the valve body 1. The outlet side A of the ball valve is connected via the drainage channel 3 to the passage 2, but not to the inside diameter 9 of the ring seal 8 and the subsequent drainage opening in the housing. In the second position, there is no emptying.
- valve body is shown in its third, so-called emptying position.
- the inlet side E of the ball valve is still closed by the valve body 1.
- the valve body is rotated relative to the position shown in FIG. 2 so that the outlet side A of the ball valve is connected via the drainage channel 3 and the passage 2 to the inside diameter 9 of the ring seal 8 and the subsequent drainage passage in the housing.
- the outlet side of the ball valve is therefore connected to the emptying passage provided in the housing. This means that the associated line section on the outlet side of the ball valve can be emptied.
- the valve body can be rotated into the second position shown in FIG. 2 in order to prevent contaminants from the environment from entering the passage 2 and / or via the emptying passage or the emptying opening reach the outlet side of the ball valve via the drainage channel 3.

- the ball valve shown in FIG. 4 can be actuated by an actuating handle 14 which is connected via a spindle 15 to a valve body (not visible in FIG. 4).
- the valve body can be brought into different positions via the actuating handle 14. In a so-called emptying position, the outlet side of the ball valve is connected to an emptying hose 18.
- connection flange 19 is attached to the side of the passage 12 facing away from the connection flange 13.
- water supply lines can be connected to the connecting flanges 13 and 19.
- a passage 20 extends from the passage 12 and, together with the passage 12, forms a T-piece.
- the input side of the passage 20 is labeled E.
- the output side of the passage 20 is designated A.
- the passage 20 is formed in the interior of a riser 22.
- the riser 22 merges into a basic housing body 24, which has both a larger inner diameter and a larger outer diameter than the riser 20.
- a passage 28 in the form of a through hole is provided in the valve body 26.
- An emptying channel 29 extends from the passage 28 and is arranged radially to the passage 28.
- the valve body 26 is located on the input side E on the inside diameter of an annular seal 31 which is fixed in the housing base body 24.
- the valve body 1 is in contact with an annular seal 32, which is fixed in a housing closure body 34, which in turn is screwed into the housing base body 24.
- a connector 35 with an internal thread 36 and an external thread 37 is formed on the housing closure body 34.
- valve body 1 is in contact with an annular seal 41, which is fixed on the inlet side of the ball valve in the vicinity of the passage 20 in the housing base body 24.
- annular seal 41 which is fixed on the inlet side of the ball valve in the vicinity of the passage 20 in the housing base body 24.
- the housing base body 24 is provided with an emptying hole 43 in which one end of the emptying hose 18 is fastened.
- both the inlet side E of the passage 20 and the drain opening 43 are closed.
- the position of the valve body 26 shown in FIG. 5 corresponds to the position of the valve body 1 shown in FIG. 2.
- the valve body 26 of the embodiment shown in FIG. 5 can also be brought into the positions shown in FIGS. 1 and 3 become.
- the housing 10 or the housing base body 24 shown in FIG. 5 can be manufactured with or without an emptying bore 43 from one and the same blank.
