Description

Water pipe crossing preventing valve device adaptable to water pressure fluctuation environment
Technical Field
The invention relates to the technical field of zero-cold water heaters, in particular to a water crossing preventing pipe valve device suitable for a water pressure fluctuation environment.
Background
When the zero-cold water heater in the prior art is installed and applied in a pipeline environment without a hot water return pipe, the most universal method for establishing the water flow circulation condition is to install an H-shaped cold and hot water pipeline connecting piece in the prior art at a water consumption point which is farthest away from the water heater in the pipeline environment, and connect the cold water pipe and the hot water pipe of the water consumption point in series to ensure that normal-temperature water stored in the hot water pipeline can flow back to a cold water inlet of the water heater through the cold water pipe under the driving of a circulating device of the zero-cold water heater, and the normal-temperature water is heated by the water heater and then is conveyed to the water consumption point communicated with the H-shaped cold and hot water pipeline connecting piece in the prior art through the hot water pipeline again so as to achieve the aim of circularly heating the water stored in the hot water pipeline. (see FIG. 9)
The H-shaped cold and hot water pipe connecting piece in the prior art is composed of a transverse pipe internally provided with a check valve in the prior art and two tee joints (see figure 12), and the check valve in the prior art is mainly used for ensuring the unidirectional flow of water flow in a hot water pipe, preventing the water flow of a cold water pipeline from flowing into the hot water pipe and simultaneously having the function of preventing the water flow with smaller flow from one side of the hot water pipe from entering the cold water pipeline.
In practical application, various types of cold and hot water using points such as kitchens, toilets and flushing toilets generally exist in the environment of water pipelines governed by a zero-cold water heater, and an 'H-shaped cold and hot water pipeline connecting piece' in the prior art has the following problem in compatibility with the zero-cold water heater in use, namely when a user uses the flushing toilet at any water using point or opens a cold water faucet to use cold water, water flow in a hot water pipeline on one side of the 'H-shaped cold and hot water pipeline connecting piece' generally flushes a check valve to be communicated with a cold water pipeline on the other side, so that a phenomenon of mistakenly igniting a burner of the water heater occurs, and the use experience of the user is influenced. (see FIG. 10)
In the pipeline environment without a hot water return pipe, the water flow flowing from one side of the hot water pipe to one side of the cold water pipe through the H-shaped cold and hot water pipe connecting piece is divided into the following two types:
firstly, the circulating water flow driven by the circulating device of the zero-cold water heater flows from one side of the hot water pipe to one side of the cold water pipe through the valve body of the H-shaped cold and hot water pipe connector, and the flow rate of the circulating water flow driven by the circulating device of the zero-cold water heater in the prior art through the H-shaped cold and hot water pipe connector is usually about 4L-6L per minute. It should be noted that the burner of the water heater can be ignited only when a certain flow rate is reached, and the gas water heater in the prior art usually needs a flow rate of more than 2L per minute or higher to ignite the burner, that is, the water flow of the mixed water below 2L per minute can not ignite the burner of the water heater.
Secondly, when the cold water faucet is opened or the toilet flushes and other cold water actions are used when the water temperature in the water heater pipeline environment is available, when the water pressure is high and the flow rate is large, part of the water flow in the water output of the opened cold water faucet or the flush toilet flushes the check valve plate in the H-shaped cold and hot water pipe connector in the prior art from one side of the hot water pipe and flows to one side of the cold water pipe in series, so that the burner of the water heater is started mistakenly, and the size of the interference water flow is in direct proportion to the pipeline environment pressure and the water output of the opened cold water faucet.
Because the circulating water flow of the zero-cold water heater and the interference water flow after the flush toilet is used or when the cold water faucet is opened to use cold water are in the same direction, the H-shaped cold and hot water pipe connecting piece in the prior art cannot distinguish the circulating water flow from the interference water flow and cannot prevent the interference water flow, and therefore, the phenomenon that the burner of the water heater is wrongly ignited due to the large cold water using actions of the flush toilet, the cold water faucet or the like is always a common difficult problem of zero-cold water heater products in the prior art.
Through experimental research and analysis, the two water flows flowing through the H-shaped cold and hot water pipe connecting piece have an important condition difference, namely: when the circulating water flow of the zero-cold water heater occurs, all the cold and hot water taps in the environment of the water pipeline are in a closed state, namely the pressure born by the H-shaped cold and hot water pipe connecting piece is not reduced when the circulating water flow occurs. When the interference water current that appears in a bunch flows through the valve body, because there is certain cold water tap to be opened in the pipeline environment, the play water flow size of the tap that corresponds to being opened can reduce original pressure in "H type cold and hot water pipe connecting piece" to different extents. The change of the pressure condition creates necessary working conditions for the water cross-flow prevention pipe valve device which can adapt to the water pressure fluctuation environment.
In practical application, however, the pressure standard of the domestic tap water pipeline is usually in a range of 0.1 mpa-0.4 m or even larger, different water consumption point pressures at different positions can be caused by various factors such as different areas, different stories of buildings, even different distances between water consumption points and water heaters, or the number of turns, and the like, and complicated pressure measurement and debugging processes are required for pertinently adapting to the individual pressure conditions of the pipeline environment on site; even if the debugging is completed, a more troublesome problem needs to be faced, namely, even if the same waterway pipeline has unstable water pressure due to various reasons such as equipment maintenance, water consumption peak time, water supply equipment running state and the like.

Detailed Description
In order to better understand the technical scheme of the invention, the following detailed description of the embodiments provided by the invention is combined with the accompanying drawings 1-12.
The first embodiment is as follows: a water-crossing preventing pipe valve device adaptable to a water pressure fluctuation environment, comprising: the water pressure sensing transmission device and the water flow stopping device;
the hydraulic pressure sensing transmission device comprises: the device comprises a pressure pipe barrel 1, a piston type water pressure sensing rod 2, a water pressure water flow linkage rod 3 and a water pressure water flow linkage rod positioning piece 4;
the pressure pipe barrel 1 is provided with a first opening 5, one end of the piston type water pressure sensing rod 2 is provided with a sealing device, one end of the piston type water pressure sensing rod 2, which is provided with the sealing device, extends into the pressure pipe barrel 1 in a sliding mode through the first opening 5, and the piston type water pressure sensing rod 2 keeps the pressure pipe barrel 1 in a sealing state;
the hydraulic water flow linkage rod 3 is slidably arranged on the piston type hydraulic pressure sensing rod 2, and the diameter of the hydraulic water flow linkage rod 3 is larger than that of the first opening 5;
the hydraulic water flow linkage rod positioning part 4 is arranged on one side of the hydraulic water flow linkage rod 3, and the hydraulic water flow linkage rod 3 is positioned between the first opening 5 and the hydraulic water flow linkage rod positioning part 4; the hydraulic water flow linkage rod positioning piece 4 is connected with the pipe wall of the pressure pipe barrel 1;
the water flow stopping device is arranged in parallel with the water pressure sensing transmission device;
the hydraulic water flow linkage rod positioning part 4 is arranged on one side of the hydraulic water flow linkage rod 3, and the hydraulic water flow linkage rod 3 is positioned between the first opening 5 and the hydraulic water flow linkage rod positioning part 4; the hydraulic water flow linkage rod positioning part 4 is connected with the pipe wall of the pressure pipe barrel 1, and in other embodiments, the hydraulic water flow linkage rod positioning part 4 can be indirectly connected with the pipe wall of the pressure pipe barrel 1;
the technical principle that the anti-water-crossing pipe valve device capable of adapting to the water pressure fluctuation environment can automatically adapt to the individual pressure conditions of the pipeline environment is as follows: when the piston type water pressure sensing rod 2 slides into the pressure pipe barrel 1 under pressure (different compression degrees and different penetration distances), the water pressure and water flow linkage rod 3 which slides along with the piston type water pressure sensing rod 2 due to the friction resistance relation with the piston type water pressure sensing rod 2 is always kept at a position jointed with the first opening 5 due to the blockage of the first opening 5; when the pressure is reduced, the piston type water pressure sensing rod 2 slides outwards by a corresponding distance under the action of the expansion of gas in the pressure pipe barrel 1, at the moment, the water pressure water flow linkage rod 3 moves back and forth synchronously under the action of frictional resistance between the piston type water pressure sensing rod 2 and is separated from the first opening 5, and when the piston type water pressure sensing rod 2 slides outwards synchronously to a specific distance, the water pressure water flow linkage rod 3 is limited by the water pressure water flow linkage rod positioning part 4 and always keeps a set fixed distance from the first opening 5, so that the purpose of controlling the opening and closing of the water flow stopping device is realized; the frictional resistance between the hydraulic water flow linkage rod 3 and the piston type hydraulic pressure sensing rod 2 is larger than the impact force of water flow which can be applied to the hydraulic pressure water flow linkage rod, and the position of the hydraulic pressure water flow linkage rod on the piston type hydraulic pressure sensing rod 2 cannot be changed due to the impact of the water flow;
the technical principle that the water crossing preventing pipe valve device capable of adapting to the water pressure fluctuation environment can automatically adapt to the water pressure fluctuation of the pipeline environment is as follows: the hydraulic water flow linkage rod 3 is limited in a specific interval between the first opening 5 and the hydraulic water flow linkage rod positioning part 4, and the hydraulic water flow linkage rod 3 can only slide in the specific interval no matter the pressure and the sliding distance of the piston type hydraulic pressure sensing rod 2, and the water pressure fluctuation can not change the distance between the hydraulic water flow linkage rod 3 and the first opening 5 and the position of controlling the stroke of the water flow stopping device, so that the automatic adaptation to the water pressure fluctuation phenomenon is realized, and the purpose of normally controlling the opening and closing of the water flow stopping device is realized; the hydraulic water flow linkage rod positioning piece 4 does not hinder the sliding of the piston type hydraulic pressure induction rod 2;
the invention relates to a technical principle of automatically distinguishing and identifying circulating water flow and interference water flow of a zero-cold water heater, which can adapt to a water pressure fluctuation environment, of a water-crossing-preventing pipe valve device, and comprises the following steps: the condition that all cold and hot water taps in the pipeline environment are closed when the circulating water flow of the zero cold water heater forms a complete circulating ring is required, namely, the pipeline environment and the pressure born by the valve body of the invention cannot be reduced when the circulating water flow occurs; when the water flow with interference is generated, a cold water faucet with a certain water using point in the pipeline environment is opened or a flushing closestool is used, and the pipeline environment and the pressure born by the valve body of the invention are reduced; according to the characteristic that the pressure in the valve body changes under different working states, on the basis that the pressure pipe barrel 1 senses real-time pressure change, the water flow of two different sources can be subjected to targeted reaction action through the linkage relation among the piston type water pressure sensing rod 2, the water pressure and water flow linkage rod 3 and the water flow stopping device;

in practical application, the water pressure sensing spring 11 can be formed by combining 1kg, 2kg, 3kg and 4kg of a multi-section spring with different resistance values, namely 82303060; when the pressure in the valve body is 2kg, the springs of 2kg and 1kg are pressed to work, the springs with resistance values of 3kg and 4kg are not influenced by the pressure, the spring with the resistance value of 2kg is mainly responsible for making a targeted response to the corresponding pressure change, and the like, so that the valve body can automatically adapt to and respond to the water pressure condition and water pressure fluctuation in the preset water pressure induction spring pressure range;

The anti-water-crossing pipe valve device capable of adapting to the water pressure fluctuation environment can automatically adapt to the individual pressure conditions of the pipe environment of thousands of households; the water pressure fluctuation in the preset pressure range of the water pressure sensing spring can be automatically adapted and responded, the positions of the components can be automatically adjusted according to the water pressure fluctuation condition of the installed environment, and the functional failure caused by the water pressure fluctuation is avoided. More importantly, the water crossing preventing pipe valve device adaptable to the water pressure fluctuation environment can automatically adapt to individual pressure conditions of the pipe environment of thousands of households and automatically cope with water pressure fluctuation in the using process, and the installation position and the installation method of the water crossing preventing pipe valve device adaptable to the water pressure fluctuation environment are the same as those of an H-shaped cold and hot water pipe connecting piece in the prior art.
On the basis of any one of the first to fifth embodiments, in a sixth embodiment, the method further includes: a second cross pipe 13, a first tee 14 and a second tee 15;

the hydraulic pressure sensing transmission device and the water flow stopping device are arranged in the second transverse pipe 13;
the first tee 14 is provided with a sixth opening 18, a seventh opening 19 and an eighth opening 20;
the second tee 15 is provided with a ninth opening 21, a tenth opening 22 and an eleventh opening 23;
the fourth opening 16 is connected with the sixth opening 18, and the fifth opening 17 is connected with the ninth opening 21;
in practical application, the pipe valve device capable of automatically adapting to pressure conditions and preventing cold and hot water from being connected in series is arranged at a water consumption point (the installation position and the installation method are the same as those of an H-shaped cold and hot water pipe connector in the prior art, and the pipe valve device is usually farthest away from a water heater) in a pipeline environment governed by a zero-cold water heater, the seventh opening 19 is connected with a cold water pipe leading to a cold water inlet of the zero-cold water heater, and the eighth opening 20 is connected with a cold water inlet of a water consumption point mixing valve; the tenth opening 22 is connected with a hot water pipe leading to a hot water outlet of a zero-cold-water heater, and the eleventh opening 23 is connected with a hot water inlet of a water point mixing valve;
when the zero-cold-water heater circulating device runs, circulating water flows from a hot water outlet of a water heater to the cold and hot water series prevention pipe valve device capable of automatically adapting to pressure conditions through a hot water pipe, enters the second transverse pipe 13 through the ninth opening 21 and the fifth opening 17 from the tenth opening 22 of the second tee joint 15, enters the first transverse pipe 6 through the second opening 8, flows out of the third opening 9, enters the first tee joint 14 through the fourth opening 16 and the sixth opening 18, and flows back to a water heater burner for circulating heating through a cold water pipe connected with the seventh opening 19 and leading to a cold water inlet of the water heater; (see FIG. 9)
The following respectively makes specific descriptions on the linkage relationship among the pressure pipe barrel 1, the piston type water pressure sensing rod 2, the water pressure water flow linkage rod 3 and the water flow channel stop valve plate 7, the function of the water pressure water flow linkage rod 4 and other parts and the corresponding position relationship among the parts when the cold water faucet in the pipeline environment is opened or the cold water action such as flushing by a toilet is used to generate the interference water flow, the cold water faucet opened in the pipeline environment is closed, the interference water flow is disappeared, the hot water faucet in the pipeline environment is opened and other various pressures or pressure condition changes and the water flow occurs in the valve body when the water flow occurs in the valve body, when the valve body starts to operate, the valve body of the water cross-flow prevention pipe valve device capable of adapting to the water pressure fluctuation environment is in the 'normal pressure state' and comprises the non-water-pressure state after the water flow is installed in the water pipeline environment, the valve body is in the constant pressure state after the water flow is introduced into the water pipeline environment;
under normal pressure, when the water-saving valve is installed in a water-using pipeline and then is in a non-water pressure state, the piston-type water pressure sensing rod 2 is not pressed by pressure, the internal and external pressures of the pressure pipe barrel 1 are equivalent, the rest part of the piston-type water pressure sensing rod 2 except a sealing piston is positioned outside the first opening 5 of the pressure pipe barrel 1, the water pressure sensing spring 11 arranged in the pressure pipe barrel 1 is in a natural release state, the water pressure and water flow linkage rod 3 is arranged between the first opening 5 and the water pressure and water flow linkage rod positioning part 4 and is positioned at an initial position close to or tightly attached to the first opening 5, the water flow channel stop valve plate 7 is positioned at an initial standby position which keeps a certain distance from the third opening 9 and is close to or tightly attached to the second opening 8, and the third opening 9 is unblocked; (see FIG. 1)
When the water crossing preventing pipe valve device adaptable to a water pressure fluctuation environment is installed in a pipeline environment and water is in a pressure bearing state, but no water flow occurs, the piston type water pressure sensing rod 2 is pressed and presses the water pressure sensing spring 11 arranged in the pressure pipe barrel 1 to slide deeply into the pressure pipe barrel 1, meanwhile, because the pressure is greater than the friction resistance between the water pressure water flow linkage rod 3 and the piston type water pressure sensing rod 2, the water pressure water flow linkage rod 3 is forced to slide and retreat on the piston type water pressure sensing rod 2 and is always kept at a position tightly jointed with the first opening 5 under the limiting and blocking action of the first opening 5, and meanwhile, because the water pressure water flow linkage rod 3 is greater than the first opening 5 and partially covers the third opening 9, the water crossing preventing pipe valve device is also kept at a position directly or indirectly jointed with the third opening 9 and acted on the valve plate stroke control spring 10; under the action of the valve plate stroke control spring 10, the water flow channel stop valve plate 7 is at an initial standby position which keeps a certain distance from the third opening 9, is close to or is tightly attached to the second opening 8, and the second opening 8 is unblocked in the direction of flowing to the third opening 9; (see FIG. 2)
When the circulating device of the zero-water-cooling water heater starts to operate, because all cold and hot water taps in the pipeline environment are in a closed state at the moment, the pressure condition in the pipeline environment is not changed, the hydraulic water flow linkage rod 3 is still in a position close to the first opening 5, the impact force of circulating water flow cannot counteract the resistance of the valve plate stroke control spring 10 supported by the hydraulic water flow linkage rod 3 on the water flow channel stop valve plate 7, the third opening 9 cannot be closed, and the water flow channel of the first transverse pipe 6 cannot be blocked, the circulating water flow enters the second transverse pipe 13 from the tenth opening 22 of the second tee joint 15 through the ninth opening 21 and the fifth opening 17, then enters the first transverse pipe 6 through the second opening 8, flows out of the third opening 9, then enters the first tee joint 14 through the fourth opening 16 and the sixth opening 18, and flows back to the burner circulating water heater through a cold water pipe connected with the seventh opening 19 and leading to a cold water inlet; (see FIG. 3, FIG. 9)
When a cold water faucet is opened or cold water actions such as flushing by using a toilet bowl and the like are performed in a pipeline environment to generate interference water flow, the pressure in a pipeline where the water leakage prevention pipe valve device which can adapt to a water pressure fluctuation environment is located can be reduced (the water pressure reduction amplitude is related to the flow of the opened water faucet), the water pressure induction spring 11 (the water pressure induction spring 11 can be composed of a plurality of spring sections with different force) arranged in the pressure pipe barrel 1 releases pressure and pushes the sealing piston 5 to enable the piston type water pressure induction rod 2 to slide outwards at a corresponding distance, the water pressure and flow linkage rod 3 synchronously moves along with the piston type water pressure induction rod 2 under the action of friction force and is separated from the first opening 5 and the third opening 9, the supporting point of the valve plate stroke control spring 10 synchronously moves back, and the water flow channel stop valve plate 7 can counteract the resistance of the valve plate stroke control spring 10 to slide towards the third opening 9 or completely close the third opening 9 under the impact of the interference water flow, so that the interference water flow is greatly reduced or completely blocked; (see FIG. 4)
Because the hydraulic water flow linkage rod 3 is limited to slide in the interval between the first opening 5 and the hydraulic water flow linkage rod positioning part 4, when the pressure applied to the pressure pipe barrel 1 is reduced and the piston type hydraulic pressure sensing rod 2 slides outwards under the action of the hydraulic pressure sensing spring 11, the hydraulic water flow linkage rod 3 always keeps a fixed distance from the first opening 5 under the limitation of the hydraulic water flow linkage rod positioning part 4 after sliding to a specific distance from the first opening 5, and the hydraulic water flow linkage rod 3 cannot greatly fluctuate due to the pressure in a pipeline environment and exceed the effective control range of the valve plate stroke control spring 10 and the water flow channel stop valve plate 7;
when the opened cold water faucet in the pipeline environment is closed, after the interference water flow in the valve body of the invention disappears, the water flow prevention pipe valve device in the pipeline environment and the environment adaptable to water pressure fluctuation of the invention recovers to bear a constant pressure state, the piston type water pressure sensing rod 2 is pressed to re-penetrate into the pressure pipe barrel 1, the water pressure water flow linkage rod 3 recovers to a position attached to the first opening 5 and directly or indirectly attached to the third opening 9, and under the action of the valve plate stroke control spring 10, the water flow channel stop valve plate 7 recovers to an initial standby position which keeps a certain distance from the third opening 9, is close to or is attached to the second opening 8; (see FIG. 5)
When a hot water faucet is opened in a pipeline environment, under the impact of water flow from one side of the third opening 9, the water flow channel stop valve plate 7 at a position close to or close to the second opening 8 closes the second opening 8, so that water on one side of a cold water pipe communicated with the third opening 9 is prevented from flowing to one side of a hot water pipe through the second opening 8; (see FIG. 6)
The anti-water-crossing pipe valve device capable of adapting to the water pressure fluctuation environment can automatically adapt to the individual pressure conditions of the pipeline environment of thousands of households; the water cross-over preventing pipe valve device suitable for the water pressure fluctuation environment can automatically identify and distinguish instant through water flow sources in the valve body, can allow the circulating water flow of a zero-cold water heater to normally pass, can prevent the interference water cross-over flow generated by using a flushing closestool or other cold water using actions such as opening a cold water faucet and the like, eliminates the phenomenon of mistakenly igniting a burner of the water heater, and ensures that a user is more comfortable; more importantly, the water crossing preventing pipe valve device adaptable to the water pressure fluctuation environment can automatically adapt to individual pressure conditions of the pipe environment of thousands of households and automatically cope with water pressure fluctuation in the using process, and the installation position and the installation method of the water crossing preventing pipe valve device adaptable to the water pressure fluctuation environment are the same as those of an H-shaped cold and hot water pipe connector in the prior art.
While the embodiment of the present invention has been described in detail with reference to the drawings, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
