BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a water purifier control valve, and in particular to a central water purifier control valve.

The Prior Arts

Presently, both the industrial and household water treatment systems make use of multiple valve to perform control. In recent years, control valves having flat seal structure are utilized extensively in water treatment. For the filter system control valve using flat seal structure, the pressure between the fix plate and the movable plate is large enough to ensure tight seal. However, in this way, in switching water route, the rotation torque tends to be too strong to be controlled effectively.

Therefore, presently, the design and performance of the water control valve is not quite satisfactory, and it leaves much room for improvement.

SUMMARY OF THE INVENTION

In view of the problems and drawbacks of the prior art, the present invention provides a central water purifier control valve, that is simple in design and compact in structure, to ensure that in switching water route, the rotation torque is constant and can be controlled effectively.

The present invention provides a central water purifier control valve, comprising: a valve body, a valve core component, and a lock tight cover. The valve core component is disposed vertically in the valve body, including; a cover shape valve core sleeve, having a lower opening; a valve core bottom seat plate, fixed at the lower opening of the cover shape valve core sleeve; a fix ceramic plate, disposed between an inner wall of the cover shape valve core sleeve and the valve core bottom seat plate; a movable ceramic plate, disposed between an inner wall of the cover shape valve core sleeve and the valve core bottom seat plate; and a rotation axis, disposed between an inner wall of the cover shape valve core sleeve and the valve core bottom seat plate, used to drive the movable ceramic plate into rotation, while penetrating through the cover shape valve core sleeve. The lock tight cover is used to press the valve core component tightly in the valve body, to press it onto the cover shape valve core sleeve.

In an aspect of the present invention, the central water purifier control valve further includes: an slot, disposed on an upper surface of the movable ceramic plate, used to position a lower end head of the rotation axis; a first center sink hole, disposed at a center portion of a lower surface of the movable ceramic plate; a first sink hole, a second sink hole, and a third sink hole, disposed not in communication with each other, and disposed around the first center sink hole, on a lower surface of the movable ceramic plate; a separation indent hole slot, disposed between the second sink hole and the third sink hole, and in communication with the first center sink hole; and eight through holes, disposed on the fix ceramic plate, with equal spacing to each other, such that when the fix ceramic plate is attached to the movable ceramic plate, the first sink hole covers a cross section area of the three through holes, and the second sink hole and the third sink hole cover the cross section areas of the other two through holes respectively, while the separation indent hole slot covers the cross section area of the through hole.

In another aspect of the present invention, the central water purifier control valve further includes: five through hole positions, disposed on the valve core bottom seat plate, corresponding to five of eight through holes on the fix ceramic plate, wherein three of the five through hole positions are blind hole positions, while the three blind hole positions are spaced apart by two of the five through hole positions.

In yet another aspect of the present invention, the central water purifier control valve further includes: a water input port, a water output port, and a waste water port, disposed at a middle section of the valve body, and are connected to a filter core at a bottom portion of the valve body; a water input channel, disposed at a lower portion of the valve core bottom seat plate, and in communication with the water input port; a water output channel, disposed at the lower portion of the valve core bottom seat plate, and in communication with the water output port; a waste water channel, disposed at the lower portion of the valve core bottom seat plate, and in communication with the waste water port; a central channel, disposed at the lower portion of the valve core bottom seat plate, and in communication with a filter core water output port on an upper portion of the filter core; and two water passage channels, disposed at the lower portion of the valve core bottom seat plate, and in communication with a filter core water input port on the lower portion of the filter core.

In a further aspect of the present invention, the central water purifier control valve further includes: three positioning slots, disposed beside the water input channel and the water output channel, to act in cooperation with three positioning pins at a lower surface of the valve core bottom seat plate.

In another aspect of the present invention, the water input channel, the water output channel, the waste water channel, the two water passage channels, and the three positioning slots correspond to the eight through hole positions on the valve core bottom seat plate.

The operation principle of the central water purifier control valve is described as follows: through disposing the valve core bottom seat plate at the lower opening of the cover shape valve core sleeve, the space between the inner wall of the cover shape valve core sleeve and the valve core bottom seat plate is fixed, so that the rotation axis is able to drive the movable ceramic plate to rotate freely relative to the fix ceramic plate. Therefore, regardless of the magnitude of the lock tight force exerted through the lock tight cover, the pressing force between the flat-seal movable ceramic plate and fix ceramic plate can be kept constant, to ensure that, in switching water routes, the rotation torque remains constant and can be controlled effectively.

Further scope of the applicability of the present invention will become apparent from the detailed descriptions given hereinafter. However, it should be understood that the detailed descriptions and specific examples, while indicating preferred embodiments of the present invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the present invention will become apparent to those skilled in the art from the detailed descriptions.
