When the toilet water tank is empty, the water replenishing energy storage spring (67) can act on the delay valve (13) through the bar float (66) when being pressed, so that the delay valve is opened for water replenishing, when the water tank is full of water, the bar float (66) cannot transfer the pressing acting force of the button (68) to the delay valve due to the buoyancy of the water, so that when the water tank is empty again, for example, after flushing is finished, tap water cannot be replenished into the water tank through the delay valve; the side surface of the bar floater (66) close to the end of the time delay valve is provided with a water supplementing clamping iron mechanism (615), wherein an active triangular sliding block (62) is fixed with the side face into a whole, the sliding block is matched with a passive triangular sliding block (64) fixed with a water supplementing clamping iron (60), a hollow groove is formed in the upper part of a water supplementing clamping iron sheath (63) so that the passive triangular sliding block (64) can pass through and freely slide left and right, when the water tank is full of water, the rod float floats up and the water supplementing clamping iron (60) is forced to slide into the water supplementing clamping iron sheath (63), the time delay valve is relieved from limitation and can be freely bounced to reset to close water inlet, when the rod float moves downwards to press the time delay valve to a certain position, under the action of a water supplementing clamping spring (611), the water supplementing clamping slides out of the water supplementing clamping sheath and presses the delay valve to enable the delay valve not to bounce and reset, and only when the water tank is full of water, the water supplementing clamping slides into the water supplementing clamping sheath to bounce again and reset the delay valve to close water supplementing.

The toilet flushing iron clamping mechanism (610) is positioned below a lower free end surface (613) under the release state of a toilet flushing energy storage spring (65), when the water tank is anhydrous, a water supplementing floating ball (15) falls down and releases the toilet flushing iron clamping mechanism, at the moment, an iron clamp in the mechanism pops up under the action of a spring and is assisted by an end inclined surface, the center of gravity of a stop iron (612) is positioned at the right part of a shaft, so that the stop iron (612) can be in a horizontal state, the stop iron further prevents the toilet flushing energy storage spring from descending to open a toilet flushing butterfly valve through the lower end surface (613) of the toilet flushing energy storage spring, at the moment, the energy storage iron clamping mechanism (69) is in a release state, the iron clamp in the mechanism pops up under the action of the spring and is assisted by the end inclined surface, the center of gravity of the stop iron (614) is positioned at the left part of the shaft, so that the stop iron (614) can be in a horizontal state, at the moment, the toilet flushing energy storage spring (65) is in a release state when not pressed and the upper end surface of the toilet flushing energy storage spring is positioned at one above the stop iron (614) And the distance is fixed, when the toilet flushing energy storage spring is pressed, the upper end surface of the toilet flushing energy storage spring crosses the stop iron (614) and is clamped below the stop iron (614) when the toilet flushing energy storage spring is released and pressed, and the lower end surface of the toilet flushing energy storage spring cannot move downwards due to the blocking of the stop iron (612), so that the toilet flushing butterfly valve cannot be opened and is in a potential storage state to be released.

When the toilet flushing energy storage spring (65) is in an energy storage state, when the water tank is full of water, the water replenishing floating ball (15) floats up and forces the iron clamp in the toilet flushing iron clamping mechanism (610) to retract into the outer sheath of the toilet flushing iron clamping mechanism by the pulley block, the mechanism stopping iron (612) is released to release the lower end face of the toilet flushing energy storage spring, the toilet flushing energy storage spring downwards drives the toilet flushing butterfly valve to complete a toilet flushing procedure due to the fact that the upper end face of the toilet flushing energy storage spring is blocked, the lower end face of the toilet flushing energy storage spring forces the iron clamp in the energy storage iron clamping mechanism (69) to retract into the shell sheath of the energy storage spring by the pulley block in the descending process, the stopping iron (614) is released to release the upper end face of the toilet flushing energy storage spring, and the toilet flushing energy storage spring immediately bounces up to the stopping iron (614) when the upper end face of the toilet flushing energy storage spring is released because the free-state length of the toilet flushing energy storage spring (65) is greater than the distance from the stopping iron (614) to the lowest end face which can possibly stretch to the toilet flushing energy storage spring, the lower end face of the flushing energy storage spring (65) in a free state under the action of the return spring (61) goes up and passes over the stop iron (612) and is stopped or about to be stopped at the upper end of the flushing energy storage spring.

After the toilet is flushed, the water tank is in a standby state: the water tank is filled with water or is not filled with water, the toilet flushing energy storage spring does not store energy, the delay valve is closed, after one toilet flushing is finished, only the wastewater of the hand basin can be drained, but the tap water can not be replenished, and the delay valve is closed no matter the previous water is full because of the wastewater drainage or the tap water replenishing; if the water tank is not water when a button of the water tank is pressed in a standby state, the toilet flushing energy storage spring (65) is in an energy storage state, the delay valve (13) is opened and locked, at the moment, if tap water exists or no tap water exists but the tap water arrives before the waste water, the water tank is filled with the tap water and then the delay valve is closed, at the moment, if the waste water arrives before the tap water or the waste water arrives simultaneously with the tap water, the water tank is filled with the waste water or the waste water and the tap water together and then the delay valve is closed, no matter whether the waste water is drained or the tap water is supplemented, once the water tank is filled with the water and the water supplementing floating ball (15), a toilet flushing program is started, and the toilet flushing finishing water tank returns to the standby state; if the water tank has water when the water tank button is pressed under the standby state, the delay valve cannot be opened, the clamping iron and the stop iron (612) in the toilet flushing clamping iron mechanism (610) are in the release state, and the stop iron (614) cannot prevent the upper end face of the toilet flushing energy storage spring (65) from descending, so the toilet can be flushed normally at the moment, no matter how long the button is pressed, the toilet flushing energy storage spring can only ascend through the stop iron (614) due to the fact that the lower end face of the toilet flushing energy storage spring is blocked when the button is released, after the upper end face of the toilet flushing energy storage spring ascends for a certain distance, the lower end face of the toilet flushing energy storage spring ascends under the action of the reset spring and passes through the stop iron (612) to be finally positioned on the stop iron no matter the water replenishing floating ball (15) is positioned at any position, and the water tank returns to the standby state. The toilet flushing iron clamping mechanism (610) can be replaced by a structure identical to that of the water supplementing iron clamping mechanism (615), and at the moment, an active triangular sliding block of the toilet flushing iron clamping mechanism is attached to the bar floater (66), or a floater is additionally arranged to drive a passive triangular sliding block independently so as to control the stop iron (612); the energy storage clamping mechanism (69) can also be replaced by a mechanism similar to a water supplementing clamping mechanism (615), and the active triangular sliding block is attached to the lower end face of the toilet flushing energy storage spring (65) and is inverted.

The device can be changed into an electric control type to realize the same function: the floating ball water supplementing valve group and the toilet flushing valve group are cancelled, an infrared or radio frequency induction probe is installed on the front side of the water tank or the closestool, when a person approaches the water tank, and the water tank water level meter detects that the water tank does not reach the set water level, the tap water electromagnetic water supplementing valve is opened to supplement water until the water level reaches the set value, the valve is closed, when the person is detected before the closestool again, the toilet flushing electromagnetic valve is opened when the person approaches the water tank once and the water tank water level reaches the set water level, the toilet flushing electromagnetic valve is closed when the water tank water level reaches the set low value, and then the signals of the two detected persons are cleared and ready for standby.

The mechanical structure of the device can be applied to civil use, and also can be applied to mechanical structures such as industrial equipment, municipal facility equipment, military weaponry and the like, such as valves for industry and municipal administration and mechanical devices of weapon fire control systems.

Water-saving toilet cistern

First, system principle

The middle water-saving closestool water tank can utilize reclaimed water, namely waste water, of a hand basin, and before a toilet, a water valve of a switch such as a delay valve or a ping-pong valve is only needed to be pressed so as to supplement tap water when no waste water exists, namely when the water tank is not full, a flushing valve is normally pressed during flushing, only the waste water of the hand basin is allowed to enter the water tank when the toilet is idle, and the redundant waste water automatically flushes the toilet from an overflow port. The bottom of the hand basin is communicated with the water tank through a filter screen, or two flap valves are arranged, one way is directly discharged into a sewer, and the other way is communicated with the water tank to prevent impurities mixed in the wastewater of the hand basin from blocking the water tank or a closestool.

As shown in figure 1, 2 drainage flap valves 11 are arranged at the bottom of the hand basin, impurity waste water which possibly blocks a toilet bowl and a water tank is directly drained into a sewer through one path, and the rest waste water can be drained into the water tank through another path of hose communicated with the water tank of the toilet bowl and can be connected to convenient positions such as the side surface or the bottom surface, or a filter screen is arranged at a proper position of a common hand basin drainage device and communicated with the water tank to prevent impurities mixed with the waste water in the hand basin from blocking the water tank or the toilet bowl, and only one flap valve is needed at the moment, as shown in figure 12. For the wastewater of the hand basin which cannot be mixed with impurities or cannot be blocked by the mixed impurities, only a common discharge hose of the hand basin is connected to a water tank. When the device is installed, the bottom of the hand basin is ensured to be higher than the highest water level line of the water tank so as to ensure that the waste water of the hand basin can be completely discharged into the water tank.

The tap water replenishing pipe of the water tank is firstly connected with a delay valve or a ping-pong valve or other water valves 13 with opening and closing functions after passing through a movable joint, and then is connected with an inlet joint 16 of the float ball water replenishing valve through a hose, the joint is positioned at the upper ends of support columns of a float ball 15 and the water replenishing valve 14, the support columns are fixed on the movable joint of the inlet of the tap water replenishing pipe of the water tank, are hollow inside and are communicated with the water replenishing valve 14, but are not directly communicated with the tap water replenishing pipe of the water tank, but are communicated with the tap water replenishing pipe of the water tank through the delay valve or the ping-pong valve or other water valves 13 with opening and closing functions, namely, the tap water can reach the front of the float ball water replenishing valve through the valves, so that the valves can control the water replenishing function of the float water replenishing valve. Before using the toilet, only a delay valve or a ping-pong valve button 18 is needed to be pressed or other water valves 18 with opening and closing functions are needed to be opened so as to supply tap water when the hand basin has no waste water, namely when the water tank is not full; before flushing the toilet after the water tank is completely replenished with tap water, the ping-pong valve needs to be pressed once again, other water valves with opening and closing functions but without automatic closing functions need to be closed to forbid the subsequent automatic water replenishing of the floating ball water replenishing valve, and the delay valve does not need to be pressed again and has a delayed automatic closing function; when the toilet is in idle, only the wastewater of the hand basin is allowed to enter the water tank, and the tap water is not allowed to be supplemented, the redundant wastewater automatically flushes the toilet through the overflow port of the water tank, and the overflow channel of the toilet water tank is adapted to the discharge capacity of the hand basin so as to prevent the water in the water tank from overflowing. The water replenishing valve 14 in the floating ball water replenishing valve group (19) is inverted, namely, a valve clack moves upwards to be closed and opens downwards, a floating ball is positioned above the water replenishing valve, and a groove is formed in the side surface of the floating ball so as to install a screw rod for adjusting the water level; or the valve clack is suspended on two sides of the floating ball by a lead screw and a hanging chain with adjustable length; or the valve body of the water replenishing valve 14 is designed to be a middle permeable type, and the middle part of the water replenishing valve penetrates through a water level adjusting screw rod connected between the valve clack and the floating ball, so that the valve clack can be only connected with the screw rod, and the water replenishing valve is simple and compact. One of the full-discharge and half-discharge buttons 18 of the water tank is used for pressing a valve 13 such as a delay valve or a ping-pong valve, namely a tap water replenishing control valve, and the other one is used for pressing a full-discharge flushing valve 17. The functions required by the device can be obtained by modifying a common floating ball water replenishing valve.

The delay valve used by the device is a delay valve in the prior art, has the function of switching on and off the tap water, opens the valve to start water supply when the valve is pressed to the bottom or not, and automatically closes the water supply after a certain time delay, wherein the delay time of the delay valve is based on the time for the matched closestool water tank to supplement the tap water to a set water level line at one time when the closestool water tank is free of water.

When the cross valve rod is repeatedly pressed and under the action of a return spring, the opening and closing rod can only rotate clockwise or anticlockwise along the sliding chute 41 and is repeatedly stopped at two highest extreme point positions of the corresponding sliding chute in sequence, and the opening and closing positions of the corresponding valve are corresponding to

positions

43 and 42 in figure 3, so that the valve clack can be repeatedly positioned at the opening or closing position of the valve in sequence when the cross valve rod of the ping-pong valve is repeatedly pressed, the cross valve rod can only move up and down relative to the valve body, and the sliding iron can only move horizontally;

the appearance of the ping-pong valve shown in fig. 2 should be changed to accommodate the need for fitting of the associated fittings when used in the device of the present invention.

Optimizing a ping-pong valve:

can further optimize ping-pong valve disk seat, valve clack etc. to reduce complicated structure, reduce the fault rate: as shown in FIG. 4, the diameter of the valve flap 27 is close to the inner diameter of the lower half valve body, so that the cross valve rod is limited to move only vertically, and the orientation teeth and the orientation rod are eliminated. The outer diameter of the sealing surface or the sealing ring of the valve clack 27 is smaller than the outer diameter of the valve clack, the outside of the sealing surface or the sealing ring is latticed so as to facilitate water passing, and a latticed ring can be sleeved on the circumference of the outer edge of the valve clack of which the outer diameter is smaller than the inner diameter of the lower half valve body. The valve seat 24 is the lower end surface of the upper half valve body with a straight wall inner wall, the opening and closing rod 22 and the square sliding iron 23 thereof are of a single-sided type, namely only one set, and the width of the sliding iron is not more than the inner diameter of the upper half valve body so as to be convenient for assembly.

Super water conservation table tennis valve:

The structure of the ping-pong valve is further optimized, so that a button at the top end of the ping-pong valve, namely a valve rod and a valve clack of the ping-pong valve can not be pressed down when a pipeline has no tap water, namely when no water pressure exists in the valve body; the valve rod water stop part (54) is the part of the valve rod (28) extending to the lower part of the valve clack, the hydraulic cylinder (50) is positioned at one side of the valve body at the lower part of the return spring (26), the smooth inclined surface of the piston (52) contacts with the smooth spherical contact of the stop lever (56) and is sealed with the cylinder body of the hydraulic cylinder by a sealing ring, the other end of the stop lever is locked by a pin and can not slip off, the lower part of the hydraulic cylinder is supported by a pressure-sensitive spring (51) and is provided with a pressure relief hole (55), when the temperature difference of the using environment of the ping-pong valve is small, the pressure sensing spring can be replaced by air sealed in the cylinder body, the pressure relief hole (55) can be omitted, when tap water exists, the piston moves downwards under the action of water pressure, the stop rod moves towards the inside of the cylinder body under the action of the release spring (53) of the stop rod until the outer end part of the cylinder body cannot block the water stop part (54) of the valve rod from moving upwards and downwards, and the ping-pong valve can be freely opened and closed at the moment; when no water pressure exists, namely no tap water exists, the piston (52) moves upwards under the action of the pressure sensing spring (51) of the piston and pushes the stop rod to move outwards until the outer end part of the stop rod blocks the up-and-down movement of the valve rod, so that the valve rod cannot be pressed down when no water pressure exists, namely the ping-pong valve cannot be opened at the moment.

The hydraulic cylinder can be designed into a structure which can slide left and right in the horizontal direction and is arranged on one side of the lower part of the valve body, the hydraulic cylinder is fixed by using an adjusting screw which can adjust the left and right positions of the hydraulic cylinder outside, and the size of a hydraulic threshold value which can open the valve can be adjusted by adjusting the adjusting screw.

Three, once press water-saving closestool water tank in mechanical type

The optimized middle water-saving closestool water tank is used as a normal closestool, when flushing, only one time of pressing a button on the cover of the closestool water tank is needed, after the button is pressed, if the water tank is not full of water or is not full of water, the closestool is automatically flushed, after the button is pressed, if the water level of the closestool water tank is not enough, no waste water is generated, and no tap water is supplied, the closestool cannot be flushed immediately, but once the water tank is full of water when waste water is full of the water tank or tap water is generated, the water tank automatically flushes the closestool once, and whenever the wash basin waste water has the priority of replenishing the water for the closestool water tank;

a button (68) on a toilet water tank can simultaneously press a toilet flushing energy storage spring (65) and a water replenishing energy storage spring (67) in the toilet flushing valve group shown in fig. 6, or the button (68) is designed into a two-linkage type, namely the water replenishing energy storage spring can be independently pressed, the water replenishing energy storage spring is inevitably pressed simultaneously when the toilet flushing energy storage spring is pressed, or the button is designed into a three-linkage type, namely the water replenishing energy storage spring and the toilet flushing energy storage spring can be independently pressed, and the two energy storage springs are inevitably pressed simultaneously when the middle button is pressed;

when the toilet water tank is empty, the water replenishing energy storage spring (67) can act on the delay valve (13) through the bar float (66) when being pressed, so that the delay valve is opened for water replenishing, when the water tank is full of water, the bar float (66) cannot transfer the pressing acting force of the button (68) to the delay valve due to the buoyancy of the water, so that when the water tank is empty again, for example, after flushing is finished, tap water cannot be replenished into the water tank through the delay valve; the side surface of the bar floater (66) close to the end of the time delay valve is provided with a water supplementing clamping iron mechanism (615), wherein an active triangular sliding block (62) is fixed with the side face into a whole, the sliding block is matched with a passive triangular sliding block (64) fixed with a water supplementing clamping iron (60), a hollow groove is formed in the upper part of a water supplementing clamping iron sheath (63) so that the passive triangular sliding block (64) can pass through and freely slide left and right, when the water tank is full of water, the rod float floats up and the water supplementing clamping iron (60) is forced to slide into the water supplementing clamping iron sheath (63), the time delay valve is relieved from limitation and can be freely bounced to reset to close water inlet, when the rod float moves downwards to press the time delay valve to a certain position, under the action of a water supplementing clamping spring (611), the water supplementing clamping slides out of the water supplementing clamping sheath and presses a delay valve to enable the water supplementing clamping sheath not to bounce and reset, and the delay valve bounces again to reset and close water supplementing only when the water tank is full of water and the water supplementing clamping slides into the water supplementing clamping sheath;

the toilet flushing iron clamping mechanism (610) is positioned below a lower free end surface (613) under the release state of a toilet flushing energy storage spring (65), when the water tank is anhydrous, a water supplementing floating ball (15) falls down and releases the toilet flushing iron clamping mechanism, at the moment, an iron clamp in the mechanism pops up under the action of a spring and is assisted by an end inclined surface, the center of gravity of a stop iron (612) is positioned at the right part of a shaft, so that the stop iron (612) can be in a horizontal state, the stop iron further prevents the toilet flushing energy storage spring from descending to open a toilet flushing butterfly valve through the lower end surface (613) of the toilet flushing energy storage spring, at the moment, the energy storage iron clamping mechanism (69) is in a release state, the iron clamp in the mechanism pops up under the action of the spring and is assisted by the end inclined surface, the center of gravity of the stop iron (614) is positioned at the left part of the shaft, so that the stop iron (614) can be in a horizontal state, at the moment, the toilet flushing energy storage spring (65) is in a release state when not pressed and the upper end surface of the toilet flushing energy storage spring is positioned at one above the stop iron (614) The distance is fixed, when the toilet flushing energy storage spring is pressed, the upper end face of the toilet flushing energy storage spring crosses the stop iron (614) and is clamped below the stop iron (614) when the toilet flushing energy storage spring is released and pressed, and the lower end face of the toilet flushing energy storage spring cannot move downwards due to the blocking of the stop iron (612), so that a toilet flushing butterfly valve cannot be opened and is in a potential storage state;

when the toilet flushing energy storage spring (65) is in an energy storage state, when the water tank is full of water, the water replenishing floating ball (15) floats up and forces the iron clamp in the toilet flushing iron clamping mechanism (610) to retract into the outer sheath of the toilet flushing iron clamping mechanism by the pulley block, the mechanism stopping iron (612) is released to release the lower end face of the toilet flushing energy storage spring, the toilet flushing energy storage spring downwards drives the toilet flushing butterfly valve to complete a toilet flushing procedure due to the fact that the upper end face of the toilet flushing energy storage spring is blocked, the lower end face of the toilet flushing energy storage spring forces the iron clamp in the energy storage iron clamping mechanism (69) to retract into the shell sheath of the energy storage spring by the pulley block in the descending process, the stopping iron (614) is released to release the upper end face of the toilet flushing energy storage spring, and the toilet flushing energy storage spring immediately bounces up to the stopping iron (614) when the upper end face of the toilet flushing energy storage spring is released because the free-state length of the toilet flushing energy storage spring (65) is greater than the distance from the stopping iron (614) to the lowest end face which can possibly stretch to the toilet flushing energy storage spring, the lower end surface of the toilet flushing energy storage spring (65) in a free state under the action of the return spring (61) goes upwards and passes over the stop iron (612) and is stopped or about to be stopped at the upper end of the toilet flushing energy storage spring;

after the toilet is flushed, the water tank is in a standby state: when the water tank is filled with water or is not filled with water, the toilet flushing energy storage spring does not store energy, the delay valve is closed, and at the moment, the waste water discharged by the hand basin can be only accepted, but the water can not be supplemented by the tap water, because the delay valve is closed no matter the waste water discharged or the tap water supplemented water is full before the water is full; if the water tank is not water when a button of the water tank is pressed in a standby state, the toilet flushing energy storage spring (65) is in an energy storage state, the delay valve (13) is opened and locked, at the moment, if tap water exists or no tap water exists but the tap water arrives before the waste water, the water tank is filled with the tap water and then the delay valve is closed, at the moment, if the waste water arrives before the tap water or the waste water arrives simultaneously with the tap water, the water tank is filled with the waste water or the waste water and the tap water together and then the delay valve is closed, no matter whether the waste water is drained or the tap water is supplemented, once the water tank is filled with the water and the water supplementing floating ball (15), a toilet flushing program is started, and the toilet flushing water tank returns to the standby state after the toilet flushing is finished; in a standby state, if the water tank has water when a button of the water tank is pressed, the delay valve cannot be opened, the clamping iron and the stop iron (612) in the toilet flushing clamping iron mechanism (610) are in a release state, and the stop iron (614) cannot prevent the upper end face of the toilet flushing energy storage spring (65) from descending, so that the toilet can be flushed normally at the moment, no matter how long the pressing time is, the toilet flushing energy storage spring can only ascend and smoothly pass through the stop iron (614) because the lower end face of the toilet flushing energy storage spring is blocked when the button is released, after the upper end face of the toilet flushing energy storage spring ascends for a certain distance, the lower end face of the toilet flushing energy storage spring ascends and passes through the stop iron (612) to be finally positioned above the stop iron no matter the water replenishing floating ball (15) is positioned at any position under the action of the reset spring, and the water tank returns to the standby state;

the toilet flushing iron clamping mechanism (610) can be replaced by a structure identical to that of the water supplementing iron clamping mechanism (615), and at the moment, an active triangular sliding block of the toilet flushing iron clamping mechanism is attached to the bar floater (66), or a floater is additionally arranged to drive a passive triangular sliding block independently so as to control the stop iron (612); the energy storage clamping mechanism (69) can also be replaced by a mechanism similar to a water supplementing clamping mechanism (615), and at the moment, the driving triangular sliding block is attached to the upper surface of the lower end face of the toilet flushing energy storage spring (65) and is inverted so as to realize the function of the mechanism before replacement.

The relation between the stiffness coefficients of the springs is adjusted, so that the springs are matched tacitly, the sequence relation among the actions is completed timely when the actions are on time, and the whole device is accurate and reliable in action and durable in use.

The components of the toilet flushing valve group are integrated into a sleeve, such as a cylindrical sleeve, so that the toilet flushing valve group is convenient to use, install and maintain, and the size of the toilet flushing valve group is small as much as possible.

Four, electrification

The mechanical device can be changed into an electric control type to realize the same function: the floating ball water supplementing valve group and the toilet flushing valve group are cancelled, an infrared or radio frequency induction probe and the like are installed on the front side of the water tank or the closestool, when a person approaches the water tank, and the water tank water level meter detects that the water tank does not reach the set water level, the tap water electromagnetic water supplementing valve is opened to supplement water until the set water level is reached, the valve is closed, when the person before the closestool is detected again, the toilet flushing electromagnetic valve is opened when the person approaches the water tank once and the water tank is full of water, the toilet flushing electromagnetic valve is closed when the water tank water level reaches the set low level, and then the signals of the two detection persons are cleared and ready for standby.

The economic and social benefits of the invention are as follows:

the toilet water tank can utilize the wastewater of the hand basin, if the wastewater is excessive, the toilet can be flushed through an overflow pipe in the water tank, the tap water can be automatically supplemented due to insufficient wastewater, when the toilet is flushed, if no water exists in the water tank, the water can be automatically supplemented and the toilet can be flushed when the wastewater or the tap water exists, and the wastewater has the water supplementing priority at any time; the ping-pong valve as the accessory of the device can not be opened when no water exists by repeatedly pressing the valve switch. The mechanical structure of the device can be applied to civil use, industrial equipment, municipal facilities, military weaponry and other mechanical structures. Such as valves for industrial and municipal use, mechanical devices for weapon fire control systems, etc.

The population of people using the basin is numerous in the population of china, and this figure will continue to increase as productivity develops, and the lack of availability will be unthinkable and undoubtedly irreresponsive to any advanced productivity. If each person saves 1 ton of water per month, the energy-saving and water-saving effects are astronomical figures, and the water-deficient areas can be supported by the water-rich areas, which is a resource, a consortium and a high level.
