Definitions

  • the present invention relates to a switching valve for sanitary fittings with at least one input and at least two outputs, and a closure element for selectively connecting the input with at least one of the outputs, each output in the region of the switching valve has at least one passage cross-section, which opens the changeover valve or closes.
  • a switching valve for sanitary fittings with at least one input and at least two outputs
  • a closure element for selectively connecting the input with at least one of the outputs
  • each output in the region of the switching valve has at least one passage cross-section, which opens the changeover valve or closes.
  • a switching valve is known.
  • the reversing valve shown there is designed to compensate for a negative pressure arising in the shower outlet, so as to prevent blocking of the reversing valve in a shut-off position of the shower outlet and to be able to solve this easily by hand with the actuator can.
  • the switching valve according to the invention is characterized in that it has a closure element with at least two movable sections, wherein the closure element by means of an actuating device in front of each of the outputs in the closed positions is movable, and the sections for opening of partial cross-sections are successively movable against an overpressure.
  • the closure element has, inter alia, a plurality of two or more sections, which are guided movably relative to one another on guide means.
  • the sections can optionally be moved in front of a first and a second or optionally also more outputs and close the outputs completely in each case.
  • the other sections of the closure element can then also be moved with significantly reduced operating forces. While the entire closure element is designed to be able to completely close the passage cross sections of the outlets, the partial cross sections form fractions thereof. The sum of all partial cross sections thus forms the sealing cross section.
  • the preferably relatively movable sections of a closure element can preferably be moved together in one or more closure positions and completely close the passage cross-section. Furthermore, it is advantageous if the sections close different sized partial cross-sections. Thus, it has proven sufficient if a section with a relatively small partial cross-section is first opened with very low operating forces in order to compensate for the overpressure and then be able to move the remaining sections with reduced operating forces.
  • an actuating device may preferably be provided which ensures that the sections for opening the passage cross-section are moved in a predetermined sequence.
  • Such an actuating device can, for example, perform an axial movement and grasp and take along the various sections at different points in this movement path.
  • the actuator can act on the closure element mechanically, hydraulically, electrically or pneumatically.
  • this is done in such a way that the actuator when opening first moves the section with a smaller partial cross-section and then a section with a larger partial cross-section from a closed position.
  • the switching valve is preferably designed so that the closure element is held in an un micstömten state by a force in a normal position. This corresponds, for example, in the case of a valve with a bath outlet and a shower outlet, to the position of the opened bath outlet. This means that after switching off the fluid flow, the closure element returns due to the action of force in the normal position and closes the shower outlet.
  • the closure element is held in a flow-through state by a fluid pressure of a fluid flowing through in a switched position.
  • This is a further closure position, which may correspond, for example, a sealed tray outlet. If the closure element closes the trough outlet and is held in this closure position by the fluid flowing through, then it can return to the basic position after the fluid flow has stopped.
  • the smaller cross section is moved to open against an overpressure of the fluid pressure. This means that the operator has to overcome the force exerted by the fluid pressure on the partial cross-section of the section. Since this is a small partial cross section, this force of the fluid to be overcome is significantly reduced. Further preferred is the embodiment according to which the force and the partial cross-sections are tuned to the fluid pressure such that the fluid pressure keeps the closure element against the force in the switched position.
  • the smaller cross section closes less than 60%, preferably less than 40% of the larger partial cross section.
  • the present invention can be preferably used in connection with a sanitary fitting with a changeover valve according to the invention. This is preferably done in connection with sanitary fittings having at least two outputs, which is usually an outlet for a tub or shower outlet and a second intended for a shower outlet.
  • Figure 1 is a sectional side view of a switching valve according to the invention in a switched position
  • FIG. 3 shows a closure element in an oblique view from below
  • FIG. 4 shows the change-over valve according to FIG. 1 in an intermediate position
  • Figure 5 shows the switching valve of Figure 1 in a normal position.
  • FIG. 1 shows an inventive switching valve 1 is shown in a side sectional view, wherein the switching valve 1 is arranged in a sanitary fitting 2.
  • On the right side there is an inlet 3 for mixed water, on the left side of a first output 4, which is designed as a tub inlet and at the bottom of a second output 5, which is designed as a shower outlet.
  • the housing has a first passage cross section 6 and a second passage cross section 7, which can be closed alternately by a closure element 8 of the changeover valve 1.
  • the closure element 8 comprises a first section 9 and a second section 10, which can be moved relative to one another.
  • the position in which the closure element 8 bears against the contact surface of the second passage cross-section 7 forms the basic position.
  • the position shown in FIG. 1 is a switchover position in which the closure element 8 rests against the contact surface of the first passage cross-section 6.
  • the force applied by the spring 11 and the cross-sectional areas of the sections 9 and 10 are dimensioned such that a pressure force exerted by the fluid flowing through holds the closure element 8 in the switching position shown.
  • the fluid flowing through is under an overpressure and counteracts an automatic resetting of the reversing valve 1 into the basic position.
  • the embodiment shown here shows a switching valve for a low-pressure fitting.
  • the cross-sectional areas for sections 9 and 10 are relatively large. Due to the fluid pressure, a considerable operating force would now have to be exerted on an actuating device 12 in order to move the closure element out of the switchover position against the pressure force of the fluid 8.
  • the fluid can now flow in the direction of the first output 4, which leads to an increase in pressure in the region of the first output 4.
  • the opening of the entire first passage cross-section with significantly reduced operating forces is possible by the actuator 12 is further depressed and after the second section 10 and now the first section 9 from the switching position moved in the direction of the basic position. This process is additionally supported by the spring 1 1.
  • the closure element 8 according to the invention is shown in an oblique view from above.
  • the first section 9 seals a larger partial cross-section 14 and the second section 10 a smaller partial cross-section 13. It is important for the present invention that the entire passage cross-section 6 or 7 is divided into partial cross sections 13, 14. In the present embodiment, the partial cross-section 13 is formed smaller than the partial cross-section 14. However, they can also be the same size or have other size ratios with appropriate design. It is important in the present case that the partial cross sections are switched to the fluid pressure and the switching operation of the individual sections takes place successively.
  • the first section 9 is attached to a sleeve 16, which is arranged displaceably on the axis 15. This makes it possible to move the second section 10 separately from the first section 9.
  • FIG. 3 shows the closure element 8 in an oblique view from below. It can be clearly seen that the smaller cross section 13 is closed by the second section 10 and the first section 9 closes a larger partial cross section 14. Both sections 9 and 10 are guided on an axis 15.
  • FIG. 4 shows the changeover valve 1 according to FIG. 1 during a changeover operation. The axis 15 is opposite to the actuator 12 via the moved by the spring 1 1 force and against the fluid pressure moves down and thereby releases the small partial cross-section 13.
  • a snap ring 17 fastened to the axle 15 abuts against the sleeve 16 and moves the sleeve 16 together with the first section 9 fixedly connected to the sleeve 16 downwards, when the actuating movement is continued.
  • FIG. 5 shows the changeover valve 1 in the basic position, in which the second output 5 is closed and the first output 4 is open.
  • the second passage cross-section 7 is sealed by the second section and the first section 9 is in direct contact with the second section 10. Both the fluid pressure and the force exerted by the spring 1 1 force hold the closing element 8 in this basic position.
