Description

Technical Field

[0001] The present invention relates to the technical field of domestic water tanks, and particularly to a domestic water tank with a surge prevention structure. Background Art

[0002] Domestic water tanks are used to store domestic water. When there is a failure in the municipal water supply, they provide backup domestic water for places such as communities, restaurants, and hotels. The uses of domestic water tanks are very extensive.

[0003] Chinese Patent Application No. 2018210749585 discloses a partitioned domestic water tank. The key points of its technical solution include a box body, a manhole provided at the top of the box body, a water inlet provided at the top of the box body, and a water outlet provided at the lower side of the box body. A cross-shaped partition board is provided inside the box body. There is a gap between the upper end of the partition board and the top wall of the box body. The partition board divides the box body into four separate chambers. The number of water outlets is four, and they are respectively provided at the lower sides of the side walls of the four chambers, having the effect of reducing the loss of water resources when the box body is damaged.

[0004] When the above domestic water tank operates, tap water enters the box body from the water inlet pipe. When the water level sensor in the electric signal pipe detects that the water level reaches the highest water level, the water inlet pipe stops water inlet. However, when tap water directly enters the box body from the water inlet pipe, it will generate surges. Surges are likely to cause water to overflow and also produce relatively large noises. Secondly, in some remote areas without tap water, the above domestic water tank is difficult to apply. Therefore, we propose a domestic water tank with a surge prevention structure. Summary of the Invention

[0005] The purpose of the present invention is to provide a domestic water tank with a surge prevention structure for the deficiencies of the prior art. By the movement of the plugging block towards the installation sleeve, the conductive head is driven to insert into the conductive groove to energize the power pump. The power pump pumps the water flow in the river or lake into the water delivery pipe. The water flow enters the control water tank along the water through pipe. The water flow in the control water tank enters the collection water tank through the U-shaped pipe. Among them, the control water tank plays a buffering role to avoid the direct impact of the water flow into the collection water tank and generate relatively large surges, prevent the float valve from starting frequently, and reduce the noise of water passing.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A domestic water tank with a surge prevention structure includes a collection water tank. A control water tank is provided inside the collection water tank. A U-shaped pipe is provided on the control water tank. A water delivery pipe is provided on one side of the collection water tank. One end of the water delivery pipe is provided with a float valve mechanism, and the other end of the water delivery pipe is connected to a power pump;

[0008] The float valve mechanism includes a fixed sleeve, which is installed at one end of the water pipe, a water pipe is provided below the fixed sleeve, two groups of fixed plates are installed at the bottom of the fixed sleeve, a rotating rod c is rotatably provided between the two groups of fixed plates, a swing rod is installed on the rotating rod c, a ball is installed at one end of the swing rod, an avoidance groove is opened in the fixed sleeve, a toggle rod is installed at the other end of the swing rod, and a blocking block is provided in the fixed sleeve;

[0010] The cooling component includes: a rotating rod a, which is rotatably arranged in the swing rod; a containing cavity a and a flow groove a are provided in the sphere, and a flow groove b is provided in the swing rod; a conductive groove and a cooling cavity are provided in the conductive seat; a driving blade a, which is installed on the rotating rod a and is arranged in the containing cavity a; an inlet pipe, which is arranged between the flow groove b and the cooling cavity; an exhaust pipe, which is arranged on the conductive seat; a driving component, which is installed on the fixed sleeve; and a heat dissipation component, which is installed on the sphere.

[0011] The driving assembly includes: a fixed block, which is installed in the water pipe and one end of the fixed block extends to the outside of the water pipe; a rotating rod b, which is rotatably arranged on the fixed block and arranged in the water pipe; a driving blade b, which is installed on the rotating rod b; a rotating shaft, which is rotatably arranged on the fixed block outside the water pipe; a belt, through which the rotating rod b and the rotating shaft are connected; a protective cover, which is installed on one side of the fixed sleeve; and a transmission assembly, which is installed in the protective cover.

The siphon is triggered by the water level gradient, and the water levels of the control water tank and the collecting water tank can change independently. By optimizing the volume of the control water tank and the diameter of the siphon pipe to ensure the performance of the device, the open upper mouth of the control water tank is more conducive to the stable operation of the device.

[0015] A filtering mechanism is arranged on the water delivery pipe.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) In the present invention, the blocking block moves towards the installation sleeve, driving the conductive head to insert into the conductive groove to energize the power pump. The power pump pumps the water in the river or lake into the water delivery pipe, and the water flows into the control water tank along the water through pipe. The water in the control water tank enters the collection water tank through the U-shaped pipe. The control water tank plays a buffering role to avoid large surges generated when the water directly rushes into the collection water tank, prevent the float valve from starting frequently, reduce the noise of water passing, and in some remote areas without tap water, the living water tank of the present invention can be well applied.

[0021] (2) When the water tanks, i.e., the collection tank and the control tank, are full of water, the buoyancy of the water drives the swing rod to swing upward, driving the toggle rod to move the plugging block towards the water delivery pipe. At this time, the plugging block seals the inside of the fixed sleeve, and the water delivery pipe is not connected to the water through pipe; as the plugging block moves towards the water delivery pipe, it drives the conductive head away from the conductive groove, cutting off the power supply to the power pump, and no water flows through the water delivery pipe (achieving the water stop effect). When the water level in the control tank is lower than a certain height, the water inlet process is entered again, realizing the intelligent regulation of the domestic water tank.

[0022] (3) In the present invention, water flows along the water through pipe into the control tank, driving the driving fan blade b to rotate. Through the belt, the rotating shaft and the bevel gear a are driven to rotate. Through the bevel gear b, the transmission rod, the worm a, and the worm gear a, the rotating shaft is driven to rotate. Through the bevel gear c and the bevel gear d, the rotating rod a is driven to rotate, driving the driving fan blade a to rotate, pumping the water in the accommodation cavity a into the flow groove a, the flow groove b, and then into the cooling cavity through the inlet pipe, and then discharging it from the discharge pipe; the flowing water cools the conductive seat and the conductive head, preventing the temperature of the conductive seat and the conductive head from rising due to long-term power-on, and extending the service life of the conductive seat and the conductive head.

[0023] (4) In the present invention, during the process of water flowing along the flow groove a, it enters the heat dissipation pipe. The rotation of the rotating rod a drives the linkage rod to rotate, driving the heat dissipation fan blade to rotate. The air flow generated by the heat dissipation fan blade blows towards the heat dissipation pipe, synchronously dissipating the heat of the water flow in the heat dissipation pipe, enhancing the cooling effect on the conductive seat and the conductive head.

[0024] (5) The top of the control tank of the present invention is open. The control tank triggers siphonage through the change of water level. The open upper mouth of the control tank can be directly in contact with the atmosphere, and the external environment has little interference with the change of water level. The water level can truly reflect the change of water volume, facilitating the precise control of the start and stop of siphonage. Siphonage is triggered by the water level gradient, and the water levels of the control tank and the collection tank can change independently. By optimizing the volume of the control tank and the diameter of the siphon pipe, the performance of the device is ensured, and the open upper mouth of the control tank is more conducive to the stable operation of the device.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] Embodiment 1: Figures 1-9 As shown, this embodiment provides a domestic water tank with a surge protection structure, including a water collecting tank 100, a control water tank 101 is arranged in the water collecting tank 100, a U-shaped tube 102 is arranged on the control water tank 101, a water delivery pipe 103 is arranged on one side of the water collecting tank 100, a float valve mechanism 2 is arranged at one end of the water delivery pipe 103, the other end of the water delivery pipe 103 is connected to a power pump, and a discharge pipe 104 is arranged on the water collecting tank 100;

[0048] The float valve mechanism 2 includes a fixed sleeve 201, which is installed at one end of the water pipe 103, a water pipe 202 is provided below the fixed sleeve 201, two groups of fixed plates 203 are installed at the bottom of the fixed sleeve 201, a rotating rod c204 is rotatably provided between the two groups of fixed plates 203, a swing rod 205 is installed on the rotating rod c204, a ball 206 is installed at one end of the swing rod 205, an avoidance groove 2011 is provided in the fixed sleeve 201, a toggle rod 207 is installed at the other end of the swing rod 205, a blocking block 208 is provided in the fixed sleeve 201, a groove 2071 is provided in the toggle rod 207, a slide rod 2072 is installed on the blocking block 208, and the slide rod 2072 slides in the groove 2071;

[0049] A mounting sleeve 209 is provided on one side of the fixing sleeve 201, a connecting rod a210 is provided on the blocking block 208, a conductive head 211 is installed on the connecting rod a210, a conductive seat 212 is provided on the mounting sleeve 209, the conductive seat 212 is connected to the power grid, the conductive head 211 is connected to the power pump (the wires required for power supply are not drawn in the figure), and a cooling component 22 for cooling the conductive head 211 and the conductive seat 212 is provided on the fixing sleeve 201.

[0050] In this embodiment, in the initial state, the water collecting tank 100 and the control tank 101 are empty. Under the gravity of the sphere 206, the swing rod 205 is driven to swing downward, and the toggle rod 207 is driven to toggle the plugging block 208 to move towards the mounting sleeve 209. At this time, the plugging block 208 does not block the inside of the fixed sleeve 201, and the water delivery pipe 103 is communicated with the water passing pipe 202 (a sealing ring is provided on the plugging block 208 to enhance the sealing effect).

[0051] As the plugging block 208 moves towards the mounting sleeve 209, the conductive head 211 is driven to insert into the conductive groove 2121 to energize the power pump. The power pump pumps the water in the river or lake into the water delivery pipe 103, and the water flows into the control tank 101 along the water passing pipe 202. The water in the control tank 101 enters the water collecting tank 100 through the U-shaped pipe 102. The control tank 101 plays a buffering role to prevent the water flow from directly flushing into the water collecting tank 100 to generate large surges, prevent the float valve from starting frequently, and reduce the noise of water passing.

[0052] As Figures 1-9 shown, the cooling assembly 22 includes: a rotating rod a221 rotatably arranged in the swing rod 205; a receiving cavity a2061 and a flow groove a2062 are formed in the sphere 206, and a flow groove b2051 is formed in the swing rod 205; a conductive seat 212 is provided with a conductive groove 2121 and a cooling cavity 2122; a driving fan blade a222 mounted on the rotating rod a221 and arranged in the receiving cavity a2061; an inlet pipe 223 arranged between the flow groove b2051 and the cooling cavity 2122; a discharge pipe arranged on the conductive seat 212; a driving assembly 23 mounted on the fixed sleeve 201; and a heat dissipation assembly 24 mounted on the sphere 206.

[0053] As Figures 1-9 shown, the driving assembly 23 includes: a fixed block 231 mounted in the water passing pipe 202; one end of the fixed block 231 extends to the outside of the water passing pipe 202; a rotating rod b232 rotatably arranged on the fixed block 231 and arranged in the water passing pipe 202; a driving fan blade b233 mounted on the rotating rod b232; a rotating shaft 234 rotatably arranged on the fixed block 231 outside the water passing pipe 202; a belt 235 for driving connection between the rotating rod b232 and the rotating shaft 234; a protective cover 236 mounted on one side of the fixed sleeve 201; and a transmission assembly 25 mounted in the protective cover 236.

[0054] In this embodiment, when the water tanks 100 and 101 are full of water, the buoyancy of the water drives the swing rod 205 to swing upward, driving the toggle rod 207 to move the plugging block 208 in the direction of the water delivery pipe 103. At this time, the plugging block 208 plugs the inside of the fixed sleeve 201, and the water delivery pipe 103 is not communicated with the water passing pipe 202 (to achieve the water stopping effect).

[0055] The plugging block 208 moves in the direction of the water delivery pipe 103, driving the conductive head 211 to leave the conductive groove 2121, cutting off the power supply to the power pump, and no water flows through the water delivery pipe 103 (to achieve the water stopping effect). When the water level in the control water tank 101 is lower than a certain height, the water inlet process is entered again to realize the intelligent regulation of the domestic water tank.

[0056] As Figures 1-9 shown in the figure, the transmission assembly 25 includes: a transmission rod 251 rotatably arranged in the protective cover 236; a bevel gear a 252 installed at one end of the rotating shaft 234; a bevel gear b 253 installed on the transmission rod 251, and the bevel gear a 252 and the bevel gear b 253 are meshed; a rotating shaft 254 rotatably arranged in the rotating rod c 204, and one end of the rotating shaft 254 extends outward along the rotating rod c 204; a worm gear a 255 installed at the extended end of the rotating shaft 254; a worm a 256 installed at the other end of the transmission rod 251, and the worm gear a 255 and the worm a 256 are meshed; a bevel gear c 257 installed at the other end of the rotating rod c 204; a bevel gear d 258 installed on the rotating rod a 221, and the bevel gear c 257 and the bevel gear d 258 are meshed. Figure 8 The toggle rod 207 is hidden in the structure diagram shown.

[0057] In this embodiment, the water flows into the control water tank 101 along the water passing pipe 202, driving the driving fan blade b 233 to rotate, driving the rotating shaft 234 and the bevel gear a 252 to rotate through the belt 235, driving the rotating shaft 254 to rotate through the bevel gear b 253, the transmission rod 251, the worm a 256, and the worm gear a 255, driving the rotating rod a 221 to rotate through the bevel gear c 257 and the bevel gear d 258, and driving the driving fan blade a 222 to rotate, pumping the water in the accommodating cavity a 2061 into the flow groove a 2062, the flow groove b 2051, and then into the cooling cavity 2122 through the inlet pipe 223, and then discharging it from the discharge pipe; the flowing water cools the conductive seat 212 and the conductive head 211, preventing the temperature of the conductive seat 212 and the conductive head 211 from rising due to long-term power-on, and prolonging the service life of the conductive seat 212 and the conductive head 211; it should be noted that: the driving fan blade a 222 is equivalent to a pump, pumping the water into the flow groove a 2062, and no detailed description will be given here.

[0058] AsFigures 1-9 As shown in the figure, the heat dissipation component 24 includes: a fixing cylinder 241 installed inside the sphere 206; a linkage rod 242 rotatably arranged on the fixing cylinder 241; a bevel gear e 243 installed on the rotating rod a 221; a bevel gear f 244 installed on the linkage rod 242, and the bevel gear e 243 and the bevel gear f 244 are meshed; a heat dissipation pipe 245 arranged inside the fixing cylinder 241, with both ends of the heat dissipation pipe 245 communicating with the flow groove a 2062; a heat dissipation fan blade 246 installed on the linkage rod 242, and a number of through holes 2063 are provided on the sphere 206.

[0059] In this embodiment, during the process of water flowing along the flow groove a 2062, it enters the heat dissipation pipe 245. The rotation of the rotating rod a 221 drives the rotation of the linkage rod 242, which in turn drives the rotation of the heat dissipation fan blade 246. The air flow generated by the heat dissipation fan blade 246 blows towards the heat dissipation pipe 245, synchronously dissipating heat from the water flow inside the heat dissipation pipe 245, enhancing the cooling effect on the conductive seat 212 and the conductive head 211.

[0060] It should be noted that the water flow direction is: accommodation cavity a 2061 → flow groove a 2062 → heat dissipation pipe 245 → flow groove a 2062 → flow groove b 2051 → inlet pipe 223 → cooling cavity 2122 → discharge pipe. Supplying water to flow through the settings of grooves and pipes is a conventional technical means in the art, and will not be elaborated here in detail.

For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in:

[0062] As Figures 10-18 shown, in this embodiment, a filtering mechanism 3 is provided on the water delivery pipe 103. The power pump is placed in a river or a lake, and the water in the river or the lake contains more impurities, so the filtering mechanism 3 is set up for filtering; in some remote areas without tap water, the living water tank of this embodiment can be well applied.

[0069] As Figures 10-18 shown, a linear driving member b323 is arranged in the filter housing 301, a moving block 324 is installed at the output end of the linear driving member b323, two driving rods 325 are rotatably arranged on the moving block 324, a clamping block a326 is installed on one of the driving rods 325, and the clamping block a326 corresponds to the position of the slot a3141; a clamping block b327 is installed on the other driving rod 325, and the clamping block b327 corresponds to the position of the slot b3211, the clamping block a326 and the clamping block b327 are aligned in position, the two driving rods 325 are drivingly connected through a transmission belt b328, and a rotating driving member a329 is installed on the moving block 324, and the rotating driving member a329 drives one of the driving rods 325 to rotate. It should be noted that: the linear driving member b323, the moving block 324, the clamping block a326, and the clamping block b327 are provided in two groups.

[0070] In this embodiment, the linear driving member b323 drives the clamping block a326 to insert into the slot a3141 (the two are clamped, and the state is as Figure 13 shown), at this time, the clamping block b327 is not clamped with the slot b3211, the rotating driving member a329 drives the driving rod 325 to rotate, drives the clamping block a326 and the rotating rod a314 to rotate, and since the worm gear b315 and the worm b316 are meshed, the driving screw 312 rotates, and according to the principle of screw drive, the two clamping blocks 311 are driven to move away from the rotating ring 305 (facilitating the subsequent driving of the rotating ring 305 and the filter screen 307 to flip);

[0071] The linear driving member b323 drives the clamping block b327 to insert into the slot b3211 (the two are clamped, and the state is as Figure 14As shown), at this time, the block a326 is located in the retreat groove a3142 (the block a326 is not engaged with the groove a3141), and the rotating driving member a329 drives the driving rod 325 to rotate, drives the rotating rod b321 to rotate, and drives the connecting rod b306 to rotate through the transmission belt a322, driving the rotating ring 305 and the filter screen 307 to flip 180 degrees, so that the impurities on the filter screen 307 fall into the filter shell 301.

[0072] It should be noted that: after the impurities on the filter 307 fall into the filter housing 301, the rotating ring 305 and the filter 307 are driven to flip 180 degrees (restored to the original state), and the two clamping blocks 311 are driven to clamp the rotating ring 305 to fix the rotating ring 305 and the filter 307 (restored to the original state).

[0073] In this embodiment, the top of the control water tank 101 is open, and the control water tank 101 triggers the siphon through the change of water level. The open top of the control water tank 101 can directly contact with the atmosphere. The external environment has little interference with the water level change. The water level can truly reflect the change of water volume, which is convenient for accurately controlling the start and stop of the siphon.

[0074] The device uses the water level gradient to trigger the siphon, and the water levels of the control water tank 101 and the water collecting tank 100 can be changed independently. The performance of the device is ensured by optimizing the volume of the control water tank 101 and the diameter of the siphon tube, and the open upper opening of the control water tank 101 is more conducive to the stable operation of the device.

[0075] Embodiment 3: This embodiment provides a method for using a domestic water tank with an anti-surge structure, comprising the following steps:

[0076] Step 1, water inlet process: in the initial state, there is no water in the water collecting tank 100 and the control water tank 101. Under the gravity of the ball 206, the swing rod 205 is driven to swing downward, and the toggle rod 207 is driven to toggle the blocking block 208 to move toward the installation sleeve 209. At this time, the blocking block 208 does not block the inside of the fixed sleeve 201, and the water delivery pipe 103 is connected with the water pipe 202;

[0077] The blocking block 208 moves toward the direction of the installation sleeve 209, driving the conductive head 211 to insert into the conductive slot 2121, and energizing the power pump. The power pump draws water from the river or lake into the water delivery pipe 103, and the water flows into the control water tank 101 along the water pipe 202. The water in the control water tank 101 flows into the water collecting tank 100 through the U-shaped pipe 102, wherein the control water tank 101 plays a buffering role, preventing the water from directly rushing into the water collecting tank 100 to generate large surges, preventing the float valve from being frequently started, and reducing the noise of water flow;

[0078] Step 2. Intelligent adjustment: When the water tanks 100 and 101 are full of water, the buoyancy of the water drives the swing rod 205 to swing upward, driving the toggle rod 207 to move the blocking block 208 in the direction of the water delivery pipe 103. At this time, the blocking block 208 seals the inside of the fixed sleeve 201, and the water delivery pipe 103 is not connected to the through pipe 202 (to achieve the water stop effect);

[0079] When the blocking block 208 moves in the direction of the water delivery pipe 103, it drives the conductive head 211 to leave the conductive groove 2121, cuts off the power supply to the power pump, and no water flows through the water delivery pipe 103 (to achieve the water stop effect). When the water level in the control water tank 101 is lower than a certain height, the water inlet process is entered again to achieve the intelligent adjustment of the domestic water tank;

[0080] Step 3. Cooling process: The water flows into the control water tank 101 along the through pipe 202, driving the driving fan blade b233 to rotate. Through the belt 235, the rotating shaft 234 and the bevel gear a252 are driven to rotate. Through the bevel gear b253, the transmission rod 251, the worm a256, and the worm gear a255, the rotating shaft 254 is driven to rotate. Through the bevel gear c257 and the bevel gear d258, the rotating rod a221 is driven to rotate, driving the driving fan blade a222 to rotate, and pumping the water in the accommodation cavity a2061 into the flow groove a2062, the flow groove b2051, and then into the cooling cavity 2122 through the inlet pipe 223, and then discharged from the discharge pipe; The flowing water cools the conductive seat 212 and the conductive head 211, preventing the temperature of the conductive seat 212 and the conductive head 211 from rising due to long-term power-on, and extending the service life of the conductive seat 212 and the conductive head 211.

[0081] Step 4. Heat dissipation process: When the water flows along the flow groove a2062, it enters the heat dissipation pipe 245. The rotation of the rotating rod a221 drives the linkage rod 242 to rotate, driving the heat dissipation fan blade 246 to rotate. The air flow generated by the heat dissipation fan blade 246 blows towards the heat dissipation pipe 245 to synchronously dissipate the heat of the water flow in the heat dissipation pipe 245, enhancing the cooling effect on the conductive seat 212 and the conductive head 211;

[0082] Step 5. Filtration process: There are two groups of filter screens 307. One group of filter screens 307 is located below the water delivery pipe 103. The filter screen 307 filters the water in the water delivery pipe 103, and the impurities in the water remain on the filter screen 307. The linear drive member a303 drives the moving plate 304 to move, driving the filter screen 307 away from below the water delivery pipe 103, so that the other filter screen 307 moves to below the water delivery pipe 103, and this filter screen 307 filters the water flow in the water delivery pipe 103;

[0083] Step 6. Discharging process: The linear drive member b323 drives the block a326 to insert into the slot a3141 (the two are engaged, and the state is as Figure 13As shown in the figure, at this time, the clamping block b327 is not engaged with the clamping groove b3211. The rotary driving member a329 drives the driving rod 325 to rotate, driving the clamping block a326 and the rotary rod a314 to rotate. Since the worm gear b315 and the worm b316 are engaged, the driving screw 312 rotates. According to the principle of screw drive, the two clamping blocks 311 are driven to move away from the rotary ring 305 (facilitating the subsequent driving of the rotary ring 305 and the filter screen 307 to flip).

[0084] The linear driving member b323 drives the clamping block b327 to insert into the clamping groove b3211 (the two are engaged, and the state is as shown in the figure). Figure 14 As shown in the figure, at this time, the clamping block a326 is located in the retraction groove a3142 (the clamping block a326 is not engaged with the clamping groove a3141). The rotary driving member a329 drives the driving rod 325 to rotate, driving the rotary rod b321 to rotate, driving the connecting rod b306 to rotate through the transmission belt a322, driving the rotary ring 305 and the filter screen 307 to flip 180 degrees, so that the impurities on the filter screen 307 fall into the filter housing 301.

[0085] The present invention introduces a siphon trigger mechanism based on the water level gradient, and combines dynamic liquid level compensation and hydraulic buffer effect analysis, enabling the entire device to significantly reduce the action frequency of the float valve without external power. The siphon is triggered by the water level gradient. When the water level difference between the small water tank (control water tank 101) and the main water tank (collection water tank 100) reaches the critical value, the siphon system starts naturally, quickly introducing the excess water into the main water tank, thereby completing the water level balance in a short time. The innovative mechanism lies in utilizing the gravitational potential energy of the fluid itself, rather than relying on electric power or mechanical driving devices, making the system more energy-efficient. At the same time, the principle of dynamic liquid level compensation ensures that the siphon automatically stops when the water level in the main water tank drops, and prevents repeated triggering through the calculation of the volume of the small water tank and the diameter of the siphon pipe (the siphon pipe is a U-shaped pipe 102). The analysis of the hydraulic buffer effect further optimizes the water flow velocity and pressure change during the siphon process, reduces the water hammer risk, and improves the safety and reliability of the device operation.

[0086] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
