Magnetism is inhaled formula and is prevented pressure boost string water device

Technical Field

The utility model relates to the technical field of water heater and domestic hot water pipeline circulation, in particular to a pipe valve device which is suitable for a zero cold water heater product with a hot water pressurizing function and used for preventing pressurized hot water from being connected into a cold water pipeline in series.

Background

When the zero cold water heater with the hot water pressurizing function in the prior art is installed and used in a water environment without a preassembled hot water return pipeline, the most common method is to use an H-shaped cold and hot water pipe connector in the prior art in combination with the zero cold water heater, wherein the H-shaped cold and hot water pipe connector consists of a straight pipe with a built-in check valve in the prior art and two tee joints (see figure 13), and the check valve has the function of preventing the cold water pipe from flowing into the hot water pipe when a user opens a hot water tap. The specific installation and use method is that the cold water pipe and the hot water pipe are connected in series by an H-shaped cold and hot water pipe connecting piece at a cold and hot water pipe port close to a water consumption point (usually the water consumption point farthest from the water heater) in a local water consumption pipeline environment managed by the water heater, so that the cold water stored in the hot water pipeline can flow back to a cold water inlet of the water heater by a cold water pipe under the drive of a water circulating device of the zero cold water heater, and then the cold water is conveyed to the water consumption point which is connected in series by the H-shaped cold and hot water pipe connecting piece in the prior art again through the hot water pipeline after being heated by the water heater, and in this way, a water flow circulating ring is established in the pipeline environment, so that the aim of preheating the stored water in the hot water pipeline is realized (see figure 10).

In real life, due to reasons such as floors, running conditions of water supply equipment, even regional differences and the like, tap water supply pressure is insufficient or unstable, and when a water heater is used in many families, the phenomenon of small hot water output, unstable flow or unstable water pressure exists, and a zero-cold water heater producer is usually matched with a water pump with a supercharging function to increase the pressure of a hot water pipeline so as to solve the problem. However, in practical application, when the H-shaped cold and hot water pipe connector is used in combination with a zero cold water heater with a hot water pressurizing function in the prior art, the following problems exist: namely, when a user opens a certain hot water tap in the water environment for the zero cold water heater to use hot water (at this time, the booster pump starts to work), because the booster pump continuously boosts the hot water pipeline, when the pressurized hot water cannot be quickly and completely discharged from the opened hot water tap, the pressure in the hot water pipeline can be enhanced, when the pressure is larger than the resistance of the spring of the check valve in the H-shaped cold and hot water pipe connector in the prior art, the pressurized hot water in the hot water pipeline can jack the check valve in the prior art to reversely enter the cold water pipeline, the water temperature in the cold water guiding pipeline is obviously increased (figure 11), and at this time, if the cold water tap of other water points is opened, the discharged hot water is even the toilet bowl is also the hot water, the phenomenon affects the use experience of the water users of other water points, and unnecessary waste is caused.

the first piston body 11 is slidably arranged in the second transverse tube 2, one end of the first piston return spring 13 is connected with the tube wall of the second transverse tube 2, and the other end of the first piston return spring is connected with one side of the first piston body 11; the first piston body extension part 12 is arranged on one side of the first piston body 11 facing the third opening 9, the first piston body extension part 12 extends into the second cavity 5 from the third opening 9 and the second opening 7, and the first magnet 14 is arranged at the end head of the first piston body extension part 12; the first piston body 11 has a diameter larger than the third opening 9 and the fourth opening 10;

the water passing opening switch door plate 15 is arranged in the first cavity 4, and the water passing opening switch door plate 15 is rotatably connected with the pipe wall shaft of the first transverse pipe 1; the second magnet 16 is arranged on the water passing opening switch door plate 15, and the third magnet 17 is arranged on the water passing opening switch door plate 15;

the forced opening device of the water outlet switch door plate is arranged in the first transverse pipe 1;

in this embodiment, the shape of the water gate switch door plate 15 is an integral wing shape with an axis as a boundary, the second magnet 16 is disposed at one end of the water gate switch door plate 15 with an axis as a boundary and can cover the water gate 8, the third magnet 17 is disposed at the other end of the water gate switch door plate 15 with an axis as a boundary in a homopolar direction, and the second magnet 16 and the third magnet 17 can respectively attract each other with the first magnet 14 within an effective range; the water outlet switch door plate 15 is used for controlling the opening and closing of the water flow channel of the first opening 6 flowing to the second opening 7;

in other embodiments, the second magnet 16, the third magnet 17 may be replaced by a metal object that is attracted to a magnet, or the first magnet 14 may be replaced by a metal object that is attracted to a magnet;

in this embodiment, a certain gap is left between the first piston body 11 and the inner wall of the second transverse tube 2, and the water flow from the side of the first opening 6 can flow out of the fourth opening 10 through the gap, and at the same time, the first piston body 11 can slide back and forth in the second transverse tube 2 under the action of the water flow impact or the first piston return spring 13; the fourth opening 10 has the function of blocking the first piston body 11 so that it cannot come out of the second transverse tube 2, and in this embodiment, when the first piston body 11 abuts against the fourth opening 10, water flow is not prevented from flowing out of the fourth opening 10;

in this embodiment, when no water flow occurs at both sides of the first opening 6 and the fourth opening 10 and the water pressure is consistent (when both cold and hot water faucets in the pipeline environment are in a closed state and the circulation function of the zero cold water heater is not running), under the action of the first piston return spring 13, the first piston body 11 is at an initial standby position close to the fourth opening 10, at this time, the third magnet 17 disposed on the water outlet switch door plate 15 is opposite to the first magnet 14 disposed at the end of the first piston body extension 12, and is in a mutual attraction range, under the action of the mutual attraction force of the third magnet 17 and the first magnet 14, the water outlet switch door plate 15 keeps the water outlet 8 in an open state, the water flow channel of the first opening 6 flowing to the fourth opening 10 keeps an unblocked state, and the water outlet switch door plate forced opening device is at the initial standby position; (see FIG. 1 and FIG. 4)

When water flow (circulating water flow generated by zero water heater circulating pump running) to the fourth opening 10 occurs outside the first opening 6, at this time, the first piston body 11 is at an initial standby position close to the fourth opening 10, water flow can impact the water port switch door plate forced opening device to a position resisting the water port switch door plate 15, the water port switch door plate 15 is forced to keep an opening position all the time, so that the third magnet 17 cannot be separated from the suction force of the first magnet 14 due to the impact of the large circulating water flow of the zero water heater, the water port 8 is always in a continuous opening state, at this time, circulating water flow of the zero water heater enters the first cavity 4 through the first opening 6, enters the second cavity 5 through the water port 8, enters the second transverse pipe 2 through the second opening 7 and the third opening 9, and then flows out of the fourth opening 10 between the first piston body 11 and the second inner wall 2 through the fourth opening 10;

in this embodiment, when the fourth opening 10 generates water flow in the direction of the first opening 6 (at this time, since the hot water tap is opened in the pipeline environment of the zero-water heater, the pressurizing device of the zero-water heater is started to operate, the force of this water flow acting on the first piston body 11 is enough to overcome the resistance of the first piston return spring 13 to the first piston body 11, the first piston body 11 slides towards the third opening 9 to a position closing the third opening 9, the first piston body extension 12 shifts towards the water passing opening 8, the first magnet 14 arranged at the end of the first piston body extension 12 is separated from the suction range of the third magnet 17, enters the suction range of the second magnet 16, under the interaction of the first magnet 14 and the second magnet 16, the water passing opening switch door plate 15 rotates to close the water passing opening 8 immediately, and cuts off the passage of water passing through the second opening 8 into the second cavity 5 after the water passing outside the first opening 6 flows through the water passing opening 8; at this time, the forced opening device of the water port switch door plate is at an initial standby position or rotates towards the outer side of the first opening 6 under the impact of the water flow, so that the water port switch door plate 15 is not prevented from closing the water port 8 under the interaction of the first magnet 14 and the second magnet 16; (see FIG. 3, FIG. 6)

When the pressure outside the first opening 6 is consistent with the pressure outside the fourth opening 10, the forced opening device of the water passing opening and closing door plate keeps or returns to an initial standby position, meanwhile, under the action of the first piston return spring 13, the first piston body 11 is separated from the third opening 9 and returns to the initial standby position of re-attaching the fourth opening 10, the first magnet 14 arranged at the end of the first piston body extension part 12 moves back along with the first opening and closing door plate, and is separated from the attraction range of the second magnet 16 and returns to the attraction range of the third magnet 17, and under the action of the first magnet 14 and the third magnet 17, the water passing opening and closing door plate 15 rotates and returns to the position of opening the water passing opening 8; the water flow channel between the first opening 6 and the fourth opening 10 is restored to be smooth (see fig. 1 and 4);

regarding the action of the forced opening device of the water opening/closing door plate, two problems to be described are that, firstly, when the water opening/closing door plate 15 is at the position of closing the water opening 8, even if the pressure outside the fourth opening 10 is reduced to be smaller than the thrust of the first piston return spring 13 at this time, the first piston body 11 is moved back so as to cause the first magnet 14 to retract to the attractive force range with the third magnet 17, as long as the pressure from the pipeline outside the first opening 6 received by the water opening/closing door plate 15 is greater than the attractive force between the first magnet 14 and the third magnet 17, the water opening/closing door plate 15 is kept at the position of closing the first opening 6, and the water flow from the first opening 6 is prevented from entering the second cavity 5 through the water opening 8 until the water pressure at both sides of the first opening 6 and the fourth opening 10 are restored to be consistent, and then the water opening/closing door plate 15 is kept at the initial standby position of the first magnet 14 and the third magnet 17; secondly, in practical application, when the zero-water heater operates at a larger circulation flow, the circulation water flows through the valve body to impact the water outlet switch door plate 15, when the impact force is larger than the attractive force between the first magnet 14 and the third magnet 17, the water outlet switch door plate 15 can be caused to be closed by mistake, so that the circulation of the zero-water heater is interrupted, in order to ensure that the circulation water with larger flow from the zero-water heater outside the first opening 6 smoothly flows to the fourth opening 10 through the water outlet 8, the attractive force between the first magnet 14 and the third magnet 17 needs to be increased under the condition that the forced opening device of the water outlet switch door plate is not installed, so as to prevent the water outlet switch door plate 15 from being closed by mistake under the impact of the large-flow circulation water flow; however, increasing the attractive force between the first magnet 14 and the third magnet 17 brings about another problem, especially in the water environment with low water pressure in the pipeline environment, when the hot water faucet is opened and the pressurization function of the zero-cold water heater is operated, when the pressure outside the fourth opening 10 is reduced to be smaller than the force of the first piston return spring 13, the first piston body 11 moves back under the action of the first piston return spring 13, so that the first magnet 14 moves back to the attractive force range with the third magnet 17, and at the moment, if the attractive force between the first magnet 14 and the third magnet 17 is greater than the pressure from the outside of the first opening 6 to act on the water opening switch door plate 15, the water opening switch door plate 15 is restored to the initial standby open position under the attractive action of the first magnet 14 and the third magnet 17, and the water opening 8 cannot be opened, so that the pressurized hot water in the hot water pipeline cannot be prevented from flowing into the cold water pipeline; the forced opening device of the water passing opening and closing door plate 15 has the function of forcing the water passing opening and closing door plate 15 to be in an opening position when the zero water heater operates at a larger circulation flow rate, and continuously keeping the water passing opening 8 in a smooth state; meanwhile, on the basis of the conditions, the attraction force between the first magnet 14 and the second magnet 16, particularly between the first magnet 14 and the third magnet 17, can be weakened, and only the water outlet switch door plate 15 is ensured to normally rotate under the condition that the first magnet 14, the second magnet 16 and the third magnet 17 are alternately replaced, so that when the water outlet switch door plate 15 is positioned at a position for closing the water outlet 8, the pressurized pressure from the outer side of the first opening 6 is larger than the attraction force between the first magnet 14 and the third magnet 17, and the water outlet switch door plate 15 is ensured to be continuously kept at the position for closing the water outlet 8 in the operation process of the pressurization function of the zero-water heater;

in this embodiment, the first magnet 14, the second magnet 16, the third magnet 17, and the forced opening device of the water outlet switch door plate change in position due to the change of the water flow direction and the pressure condition at two sides of the first opening 6 and the fourth opening 10, and the rotation of the water outlet switch door plate 15 is controlled by using the alternate adsorption of the first magnet 14, the second magnet 16, and the third magnet 17, so as to achieve the purpose of opening or closing the water outlet 8, and on this basis, the impact effect of the water flow from different directions on the forced opening device of the water outlet switch door plate is also utilized to achieve the control of the position state of the forced opening device of the water outlet switch door plate, so as to achieve the purpose of maintaining the opening state of the water outlet switch door plate 15 by the forced opening device of the water outlet switch door plate, and ensuring that the zero-cooled water heater can operate with maximum circulation flow; the magnetic anti-pressurization water-flowing device has the basic functions of the check valve in the prior art, solves the problem that hot water flow with increased pressure in the hot water pipeline flows into the cold water pipeline when the booster pump of the zero cold water heater works, can prevent the phenomenon that the water flow channel of the zero cold water heater is closed by mistake when the zero cold water heater operates at a larger circulation flow, improves the working efficiency, and provides more comfortable application effect.

On the basis of the first embodiment, in the second embodiment, more specifically, the water flow channel opening and closing control device further includes: a one-way valve device; the first piston body 11 is provided with a water hole 18;

the check valve device comprises a check valve plate sleeve 19, a check valve plate 20 and a check valve plate return spring 21;

the check valve device is arranged on one side of the first piston body 11 facing the fourth opening 10; one end of the check valve plate sleeve 19 is communicated and butted with the water passing hole 18 on the first piston body 11, the check valve plate 20 is slidably arranged in the check valve plate sleeve 19, one end of the check valve plate return spring 21 is connected with one side of the check valve plate 20, and the other end of the check valve plate return spring is connected with the pipe wall of the check valve plate sleeve 19; (see FIG. 1 and 9)

The first piston body 11 has a diameter larger than the fourth opening 10; in practical application, the wall of the check valve plate sleeve 19 can be provided in a grid shape;

in this embodiment, the check valve device is used to prevent water from outside the fourth opening 10 from flowing through the water hole 18 to the first opening 6, and simultaneously facilitate water from the first opening 6 to flow to the fourth opening 10, so that the first piston body 11 is tightly or seamlessly combined with the inner wall of the second transverse tube 2, and water from the first opening 6 or the fourth opening 10 flows in both directions or cannot flow in both directions between the first piston body 11 and the inner wall of the second transverse tube 2; when the first piston body 11 is close to the opening of the fourth opening 10, and when the water flow from the first opening 6 to the fourth opening 10 occurs (the circulating water flow generated by the running of the circulating pump of the zero cold water heater is generated at this time), the water flow can push the check valve plate 20 to enter the check valve plate sleeve 19 and flow out from the side wall of the check valve plate sleeve 19 due to the fact that the water flow can pass through the gap between the first piston body 11 and the inner wall of the second transverse tube 2 in a very small amount or not at all, the impact force of the water flow on the check valve plate 20 is larger than the resistance of the check valve plate return spring 21 on the check valve plate 20; when water flow flowing to the first opening 6 occurs outside the fourth opening 10 (at this time, because a hot water tap is opened in the pipeline environment of the zero water heater, the pressurizing device of the zero water heater is started to operate, and because water flow can only pass between the first piston body 11 and the inner wall of the second transverse pipe 2 or not, the impact force of the water flow on the first piston body 11 is larger than the resistance of the first piston return spring 13, the water flow pushes the first piston body 11 to slide towards the third opening 9 to close the third opening 9, and the water flow outside the fourth opening 10 cannot flow to the first opening 6; the magnetic anti-pressurization water-flowing device has the basic functions of the check valve in the prior art, solves the problem that hot water flow with increased pressure in the hot water pipeline flows into the cold water pipeline when the booster pump of the zero cold water heater works, can prevent the phenomenon that the water flow channel of the zero cold water heater is closed by mistake when the zero cold water heater operates at a larger circulation flow, improves the working efficiency, and provides more comfortable application effect.

On the basis of the first embodiment, in the third embodiment, more specifically, the forced opening device of the water port switch door plate includes a water flow sensing plate 22;
