A central control valve

Abstract

A centralized control valve integrates multiple water inlet selection operations (hot and cold water) and on / off or flow regulation operations into a single button / knob. Rotating the button selects the water inlet, while repeatedly or moderately pressing the button opens / closes the water inlet or regulates the flow rate. Various valve control devices based on prior patents, mounted on the top of the valve, are mechanically hinged to the ceramic valve stem of this application. This converts the axial vertical movement of the button valve stem into a vertical deflection movement of the valve stem along its horizontal axis, while simultaneously transmitting the axial horizontal torsional torque of the button valve stem. This achieves the aforementioned operations, making the valve operation more convenient, safer, and more reliable, thus improving daily life, increasing work efficiency, and enhancing enjoyment.

Description

Technical Field

[0001] This invention relates to a water valve, particularly a centrally controlled water valve, which, through a mechanical hinge connection, can be equipped with only one button / knob to enable selection of water inlet for multiple water inlets and their on / off or flow regulation; utilizing a single-inlet ceramic valve core, connected to a single-cooling valve core handle via a large-angle oblique thread pair, it can achieve the function of repeatedly pressing the button on the top of the single cooling water valve to open or close its water inlet or regulate its flow.

[0002] This water valve can be used for switching or flow regulation of other fluids. The various mechanical structures described in this device can be applied not only to civilian equipment, but also to industrial equipment, municipal facilities, and military weaponry, such as industrial and municipal valves, weapon fire control systems, loading systems, drive systems, and other mechanical devices. Background Technology

[0003] This invention is based on invention patents ZL2022100822570, ZL2015101571809, ZL202010021227X, and existing technologies. For relevant technical features, please refer to the aforementioned patents and existing technologies. This invention utilizes various valve control devices and button-top structures from the aforementioned patents, as well as existing single-inlet cold water ceramic valve cores, hot and cold water ceramic valve cores, and multi-inlet ceramic valve cores. Through mechanical hinge connections and large-angle oblique thread connections, it achieves the on / off or flow regulation and inlet selection operations of the ceramic valve core, as well as the on / off or flow regulation operation of a single cold water valve. This concentrates the opening, closing, or flow regulation operations and inlet selection operations of multi-inlet ceramic valve cores into a single button / knob, transforming the rotary opening and closing operation of a single inlet water valve into a repeated pressing operation to achieve its flow on / off or regulation function, making operation simple and convenient.

[0004] The valve control device of the above-mentioned invention patent is composed of various valve control systems, which can realize the vertical positioning of the valve stem, i.e., the switch positioning, or the positioning at any position. For the specific structure, please refer to the above-mentioned patent.

[0005] The aforementioned ceramic valve core is a widely used combination of valve disc and valve seat with switching function. It is a finished product and almost all domestic water valves are equipped with this ceramic valve core. The valve core achieves the isolation of water flow by overlapping two highly smooth ceramic plates. A flow groove is opened on the side of the overlapping surface. By moving one of the ceramic plates, the flow groove can be opened or closed, thereby realizing the opening and closing of the water valve. When there are multiple flow grooves, the inlet can be selected by rotating one of the ceramic plates.

[0006] In general, the flow channel of a single-cooled ceramic valve core is opened and closed by rotating one of the ceramic pieces. Therefore, this invention uses a large-angle oblique thread to switch between the vertical movement of the valve stem and the rotational movement of the valve core handle, thereby realizing the opening and closing or flow regulation of the single-cooled water valve.

[0007] Currently, most industrial and civil water valves are equipped with valve handles to enable on / off switching and inlet selection, or some are equipped with push-button switches. However, these valves cannot integrate all operations into one unit. They either require pressing and waiting for automatic shut-off, or can only be turned to switch on or off, or require external rotary buttons to select the inlet, or have many inlet selection switches and / or on / off switches installed. This makes them inconvenient to use and to some extent creates opportunities and excuses for water valve leaks, which is not conducive to water conservation and the convenience of production and daily life.

[0008] This invention integrates all water valve operations into a single button / knob, effectively solving existing technical problems and organically combining water conservation and convenience. It is comfortable to use, powerful in function, and easy to operate, making it appealing to the public, encouraging water conservation, and promoting innovation. It is convenient, practical, energy-saving, and beneficial to health. Summary of the Invention

[0010] The purpose of this invention is to provide a central control valve that makes operation simpler, safer, more reliable, and significantly reduces the failure rate, thereby making people's daily lives more convenient, improving work efficiency, and adding enjoyment to life.

[0011] This invention discloses a central control valve. At least two eccentric hinge plates 22 are fixed to the lower end of a valve stem 11, which is integrally fastened to a button 14. These hinge plates are precisely clamped on the front and rear sides of a valve core handle 12, ensuring their relative movement is unobstructed and allowing the valve stem 11 to flexibly rotate horizontally relative to the valve stem axis. A hinge rod 23 is fixed to the lower part of each hinge plate. This hinge rod is precisely embedded in a through-hole sloping upward-sloping groove 21 at the upper end of the valve core handle, ensuring their relative movement is unobstructed. Pressing the button 14 causes the valve stem 11 to move vertically downwards. The hinge rod 23, fixed to the valve stem, forces the valve core handle to rotate clockwise around its horizontal axis through the groove 21, eventually stopping at the open position of the ceramic valve core 13. Conversely, pressing the button forces the valve core handle to rotate counterclockwise around its horizontal axis, eventually stopping at the closed position. By controlling the valve stem 11 to stop at different positions, the hinge rod 23 forces the valve core handle to stop at the corresponding opening position, thereby achieving flow rate adjustment.

[0012] When the valve stem 11 is in any position of the upper or lower stroke, including the open and closed positions, the button 14 is rotated left and right. The button, together with the valve stem 11 and hinge plate 22 which are fixed together, rotates left and right, thereby linking the valve core handle 12 to rotate left and right, thus enabling the ceramic valve core to select the water inlet.

[0013] The hinge drive mechanism of the valve core handle 12 formed by the hinge rod 23 and the hinge groove 21 can be replaced by the following mechanism:

[0014] A wedge 61 is fixed to the lower end of the valve stem 11. Its inclined curved surface corresponds to the upper left convex angle of the valve core handle 12 and is located to its upper left. A return rod 62 is also fixed to the lower end of the valve stem 11. It is located to the lower right of the inclined curved surface of the upper right part of the valve core handle 12. The inclined curved surface of the wedge, the inclined curved surface of the upper right part of the valve core handle 12, and the axis of the return rod are parallel.

[0015] When the valve stem moves vertically downward, the inclined surface of the wedge will drive the valve core handle to rotate clockwise through the upper left convex angle of the valve core handle. When the valve stem moves vertically upward, the return rod 62 will force the valve core handle to rotate counterclockwise through the inclined surface of the upper right part of the valve core handle 12 and return it to the initial closed position.

[0016] The central control valve has the following functions: a central control button / knob is mounted on the top of the water valve. By repeatedly pressing or moderately pressing the button, the water valve can be opened, closed or its flow rate can be adjusted. By rotating the button left or right, the water valve can be selected to select the inlet.

[0017] The single-inlet ceramic valve core's single-cooling valve core handle 32 engages with the large-angle inclined external threaded part 33 fixed to its upper end and the large-angle inclined internal threaded part 34 fixed to the lower end of the valve stem 11. By pressing the button 14, the vertically moving valve stem 11 drives the single-cooling valve core handle 32 to rotate left and right through the large-angle inclined threaded part, thereby realizing the on / off or flow regulation function of the single-inlet water valve.

[0018] The large-angle helical thread pair can also be replaced by a parallel shaft worm gear pair 41 to achieve the conversion from vertical motion to horizontal rotational motion; or a slanted groove fork 51 can be used to move the lever 52, which is horizontally fixed to the upper end of the single-cooling valve core handle 32 of the single-inlet ceramic valve core, through the through slanted groove 53, thereby achieving the conversion.

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] The centrally controlled water valve of this invention utilizes various possible valve control devices in the prior art, namely the valve control device 10 that controls the vertical movement and positioning of the valve stem to realize the functions of opening, closing, and regulating the flow of the water valve.

[0029] A pair of hinge plates 22, with their symmetrical centers offset from the valve stem axis, are fixed to the lower end of the valve stem 11. These hinge plates are precisely clamped on the front and rear sides of the valve core handle 12 of the ceramic valve core, ensuring that their relative vertical movement and the deflection movement of the valve core handle 12 relative to its horizontal axis are not obstructed. A hinge rod 23 is fixed to the lower part of each hinge plate. The hinge rod is precisely embedded in the through hinge groove 21, which opens to the upper right of the upper part of the valve core handle, ensuring that their relative movement is not obstructed. The hinge rod should be in a horizontal position and parallel to the hinge groove. The inclination direction of the hinge groove should be the same as the eccentric direction of the hinge plates and the hinge rod, and located on the same side of the valve stem to facilitate the design function and flexible operation. The hinge plates, hinge rod, and hinge groove constitute the hinge linking the valve stem and the valve core handle of the ceramic valve core, thereby converting the vertical movement of the valve stem 11 into a rightward tilting deflection movement of the ceramic valve core handle 12 around its axis 15, and transmitting the horizontal rotational movement of the valve stem along its axis.

[0030] When the ceramic valve core is in the closed position, such as Figure 1 As shown, pressing the central control knob 14 drives the valve stem 11 to move vertically downwards. The hinge 23, fixed to the valve stem, forces the valve core handle to rotate clockwise around its axis 15 through the hinge groove 21, eventually stopping at the open position of the ceramic valve core 13. Figure 2As shown, when the valve stem moves vertically upward (as is known in the background art, the return spring located under button 14 will force the valve stem to move upward after releasing the force of pressing button 14), it will force the valve core handle to stop at its original vertical position, that is, the water valve is in the closed position. By repeatedly pressing button 14, the hinge will repeatedly move, thereby realizing the opening and closing operation of the ceramic valve core. For flow-adjustable valve control devices, since the valve stem can stop at any position between the upper and lower positions corresponding to the valve core opening and closing, the hinge 23, which is fixedly integrated with the valve stem, will force the ceramic valve core handle to stop at the opening position corresponding to the valve stem stopping position, thereby realizing the flow opening adjustment.

[0031] The flow-adjustable valve control device can force the valve stem 11 to be at any position of its vertical full stroke, and the valve core handle 12 of the ceramic valve core tilts to the right at a unique corresponding angle, that is, it corresponds one-to-one with the opening value of the valve core, thereby realizing the flow regulation function or the on / off function of the water valve.

[0032] When the valve stem 11 is stopped at any position of its full vertical stroke, including the open, closed, and manually operated positions, rotating the button / knob 14 left or right will cause the hinge plate 22 to rotate left or right through the valve stem 11 which is fixed to it. The hinge plate will drive the valve core handle 12 to rotate left or right, thereby enabling the ceramic valve core to select the inlet.

[0033] The horizontal axis rotation drive mechanism of the valve core handle 12 formed by the hinge rod 23 and the hinge groove 21 can be replaced by the following hinge mechanism:

[0034] A wedge 61 is fixed to the upper left of the lower hinge plate 22 of the valve stem 11. Its inclined curved surface corresponds to the upper left convex angle of the valve core handle 12 and is located to its upper left. At the same time, a return rod 62 is fixed to the lower part of the lower hinge plate 22 of the valve stem 11, located to the lower right of the inclined curved surface of the upper right part of the valve core handle 12. The inclined curved surface of the wedge, the inclined curved surface of the upper right part of the valve core handle 12, and the axis of the return rod are parallel.

[0035] When the valve stem moves vertically downward, the inclined surface of the wedge will drive the valve core handle to rotate clockwise through the upper left convex angle of the valve core handle. When the valve stem moves vertically upward, the return rod 62 will force the valve core handle to rotate counterclockwise through the inclined surface of the upper right part of the valve core handle 12 and return it to the initial closed position.

[0036] The water valve of this invention is equipped with only one central control button / knob on its top. This central control integrates the on / off or flow regulation operations of a single inlet water valve, the on / off or flow regulation operations of multiple inlet water valves, and the inlet selection operation into a single knob / button. Switching between any operating states of this centrally controlled water valve requires manual operation; it is fully manual, facilitating operation, aesthetics, and water conservation, while enhancing the product's decorative function and the quality of life. By repeatedly pressing or moderately pressing the button / knob, the on / off or regulating valve control device can realize the on / off operation or flow regulation operation of the water valve. By rotating the button left or right, the inlet selection operation of the water valve can be achieved.

[0037] For single-cooling ceramic valve cores, the opening and closing of the water valve is generally achieved by rotating the valve core handle, or by pressing to open and automatically closing after a delay. In this invention, the single-cooling ceramic valve core handle 32 has a large-angle inclined external thread assembly 33 fixed at its upper end, which meshes with a large-angle inclined internal thread assembly 34 fixed at the lower end of the valve stem 11. By pressing the knob 14, the vertically moving valve stem 11 converts its vertical movement into horizontal rotational movement of the single-cooling valve core handle 32 through the large-angle inclined thread assembly, driving the single-cooling valve core handle 32, which is fixed to the ceramic valve core 31, to perform corresponding left and right rotational movements. This achieves the opening, closing, or flow regulation function of a single-inlet water valve. The internal and external threads of the large-angle inclined thread assembly can be interchanged. The so-called large-angle inclined thread refers to the fact that the angle formed by the internal and external thread lines and the horizontal plane is very large, generally exceeding 45°. Therefore, when one thread makes axial vertical movement, the other thread, which can rotate axially but cannot move axially or radially, will be easily forced to rotate horizontally around its axis.

[0038] The large-angle oblique external thread assembly 33 and the meshing large-angle oblique internal thread assembly 34 constitute a large-angle oblique thread assembly, a mechanical hinge of the present invention, which realizes a method for converting vertical motion into spin motion. For example... Figure 3 As shown, its thread has a relatively large inclination angle relative to the horizontal direction, which can ensure that the vertical movement of a large-angle helical thread is converted into the rotational movement of another large-angle helical thread without thread jamming or self-locking.

[0039] The aforementioned large-angle helical thread pair can also be replaced by a parallel shaft worm gear pair 41 to achieve the conversion from vertical motion to rotary motion, such as... Figure 4 As shown, its working mechanism is similar to that of a large-angle helical thread; or the through-groove 53 of the helical groove fork 51, which is fixed to the lower end of the valve stem 11 and offset from the valve stem axis, is used to move the lever 52, which is horizontally fixed to the upper end of the valve core handle of the ceramic valve core, thereby achieving the aforementioned conversion. Figure 5As shown, the vertical movement of the valve stem, i.e., the inclined groove fork 51, forces the lever 52 to rotate around the valve core handle axis by a certain angle through the through inclined groove 53, thereby realizing the adjustment of the valve core opening degree or the opening and closing operation. The inclination of the through inclined groove 53 should be kept at an appropriate value to avoid the handle from getting stuck or not moving. The inclination of the through inclined groove 53 refers to the angle formed between the extension direction of the groove and the vertical direction with an absolute value >0° and <90°.

[0040] The socio-economic benefits of this invention:

[0041] Through the technological innovation and optimization of this application, the water valve has acquired new functions and superior performance. The central control valve has a simpler mechanism, is easier to operate, is safer and more reliable, and has a significantly reduced failure rate. Thus, while actively and autonomously saving water, it also makes people's daily life more convenient, improves work efficiency, and adds to the enjoyment of life.

[0042] Conserving resources and energy is of paramount importance and should not be taken lightly. This invention makes the daily use of water valves more convenient, adds enjoyment to life, reduces the failure rate of water valves, and makes people more willing and able to save water, thereby achieving the goal of resource conservation. In view of social development, people's increasing demands for quality of life, and the continuous improvement of civic morality, convenient energy and water conservation must be organically combined with convenient production and daily life.

[0043] This invention can be used not only for water supply control, but also for other fluid flow control. The mechanical structure described in this device can be used not only for civilian applications, but also for mechanical structures in industrial equipment, municipal facilities, and military weapons, such as industrial and municipal valves, weapon fire control systems, loading systems, and drive systems.
