A water supply valve with adjustable water supply distribution

Abstract

The present application relates to a water supply valve with adjustable water supply distribution, which relates to the technical field of water supply valves, including a valve body, an opening and closing mechanism, a friction mechanism and a closing mechanism. Through the cooperation of the opening and closing mechanism and the friction mechanism, the opening of the opening and closing mechanism is gradually opened from small to large, thereby limiting the water inlet flow rate, steadily increasing the flow rate, and avoiding the occurrence of instantaneous high impact force directly impacting the diaphragm. At the same time, the rising water is used to drive the turbine with reverse damping force to rotate, thereby further reducing the impact force of the water, reducing diaphragm wear, and extending its service life. Through the cooperation of the friction mechanism and the closing mechanism, the characteristic that the turbine rotates continuously due to water leakage in the output pipeline is utilized, and the rotating block is also driven to rotate, utilizing the friction coating to generate heat during rotational friction. After long-term rotation, the heat provided by it reaches the bending heat of the bimetallic strip. When the bimetallic strip bends, the limit block releases the limit on the rectangular block, and the outer retaining ring rises to close all openings, thereby avoiding water waste caused by continuous water supply.

Description

Technical Field

[0001] The present application relates to the technical field of water supply valves, and in particular to a water supply valve with adjustable water supply amount distribution. Background Art

[0002] The water supply valve is a common automatic valve in pipelines. When the system pressure drops, the automatic water supply valve will automatically open to supply water to the system. When the set pressure is reached, the water supply valve will automatically close. Therefore, the automatic water supply valve can be used to maintain the system pressure at a stable value.

[0003] Patent publication number CN222559280U discloses an automatic water supply valve. This prior art can prevent the mounting member and the water inlet of the automatic water supply valve from loosening, thereby improving the reliability of the automatic water supply valve and facilitating packaging and installation.

[0004] However, the above-mentioned prior art has the following technical defects:

[0005] 1. When replenishing water in this prior art, the valve core assembly is moved to open the sealing port to replenish water to the upper valve cavity. However, the sealing port is directly opened to its full size, and the water flow rate and impact force entering the lower valve cavity from the water inlet are generally very large, which leads to a very high instantaneous pressure of the water entering the upper valve cavity when the sealing port is opened. The instantaneous impact force of the water will directly act on the diaphragm, causing wear thereon. At the same time, the high-speed water entering the upper valve cavity will also carry a large impact force. These impact forces will act on the diaphragm for a long time and will also wear it. The long-term wear will result in a short service life of the diaphragm, and it needs to be replaced frequently.

[0006] 2. When there is a leak in the output pipeline of the water supply valve, the water leakage will cause the water pressure in the upper valve cavity to be low and the sealing port to be open for a long time to replenish the upper valve cavity with water. The water will also be discharged from the leaking point, causing the water supply valve to be unable to close and leak for a long time, resulting in a waste of water resources.

[0007] To sum up, the existing technology still has room for improvement in extending the service life of the diaphragm and reducing water waste after the output pipeline leaks. Therefore, those skilled in the art have proposed a water replenishment valve that reduces the impact force of water on the diaphragm and stops water replenishment after the output pipeline leaks.

[0011] The friction mechanism includes a shell installed at the center of the lower side of the valve body, a bimetallic strip is arranged in the shell, and the lower end of the telescopic rod extends into the shell and is equipped with a rotating block in contact with the bimetallic strip.

[0012] A closing mechanism is also provided, which includes an outer retaining ring slidably arranged on the outside of the cylinder and a driving component. The driving component is used to allow the outer retaining ring to cover and close all openings when the bimetallic strip is bent.

[0013] Preferably, a water inlet pipe is installed on the side of the valve body, and a secondary pipe is installed on the side of the water inlet pipe and is connected to the valve body at an angle downward.

[0014] Preferably, a through hole aligned with the water inlet pipe is opened on the side of the valve body, a water outlet pipe is installed at the end of the through hole, and a one-way valve is provided in the water outlet pipe.

[0015] Preferably, the opening and closing mechanism also includes a baffle ring slidably arranged on the outside of the cylinder above the opening and connected to the inner wall of the valve body, dividing the valve body into an upper cavity and a lower cavity, and a lower baffle ring with a lower end connected to the bottom surface of the valve body is installed near the bottom of the cylinder.

[0016] Preferably, the friction mechanism also includes two mouth-shaped frames symmetrically arranged inside the shell and slidably connected to the shell and sleeved on the bimetallic strip. Both inner sides of the mouth-shaped frames are provided with strip grooves, and a slider connected to the bimetallic strip is slidably arranged in each strip groove.

[0017] Preferably, a limit block extending to the outside of the shell is installed on the side of the mouth-shaped frame, a bevel is provided on the upper side of the limit block, and the adjacent sides of the bimetallic strip and the rotating block are coated with a friction coating.

[0018] Preferably, the drive assembly allows the outer retaining ring to cover and close all openings when the bimetallic strip bends. The drive assembly includes a sealing plate installed on the side of the outer retaining ring and below the connection between the auxiliary pipe and the valve body, and a connecting rod is installed on the lower side of the sealing plate.

[0019] Preferably, a second compressed spring is sleeved on the connecting rod between the sealing plate and the bottom surface of the valve body, the lower end of the connecting rod extends to the outside of the valve body and is installed with a rectangular block, and the limit block limits the rectangular block on the same side.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The present application cooperates with the opening and closing mechanism and the friction mechanism. After the water pressure in the upper chamber decreases, the opening of the opening and closing mechanism is gradually opened from small to large, thereby limiting the water inlet flow rate, steadily increasing the flow rate, and avoiding the situation where instantaneous high impact force directly impacts the diaphragm. At the same time, the rising water is used to drive the turbine to rotate, driving the rotating block to rotate. The surface friction of the bimetallic strip allows the rotating block to apply a reverse damping force to the turbine, further reducing the impact force of the water, thereby reducing the impact force of the water on the diaphragm, reducing diaphragm wear, extending its service life, and eliminating the need for frequent replacement.

[0024] 2. The friction mechanism and closing mechanism of the present application cooperate. When water leakage occurs in the output pipeline, the upper chamber will be kept in a low-pressure state, so that the lower chamber will continue to replenish water to the upper chamber. This feature is used to make the turbine rotate continuously, driving the rotating block to rotate, and the friction coating is used to generate heat during rotation. After a long period of rotation, the heat it provides reaches the bending heat of the bimetallic strip. When the bimetallic strip bends, the limit block releases the limit on the rectangular block, and the outer retaining ring rises to close all openings, stopping the replenishment of water to the upper chamber, avoiding water waste caused by continuous replenishment. At the same time, after the temperature of the bimetallic strip drops, its shape and position are restored, and it can be used many times. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following combination Figure 1 - Figure 11 The embodiments of the present application are described in detail.

[0039] The embodiment of the present application discloses a water replenishment valve with adjustable water replenishment volume distribution. Through the cooperation of an opening and closing mechanism and a friction mechanism, after the water pressure in the upper chamber is reduced, the opening of the opening and closing mechanism is gradually opened from small to large, thereby limiting the water inlet flow rate, steadily increasing the flow rate, and avoiding the occurrence of instantaneous high impact force directly impacting the diaphragm. At the same time, the rising water is used to drive the turbine to rotate, and the rotating block is driven to rotate. The surface friction of the bimetallic strip allows the rotating block to apply a reverse damping force to the turbine, further reducing the impact force of the water, thereby reducing the impact force of the water on the diaphragm, reducing diaphragm wear, extending its service life, and eliminating the need for frequent replacement. Example 1:

[0040] like Figure 1 、 Figure 3 and Figure 5As shown, it includes a valve body 1, an opening and closing mechanism 3 is provided in the valve body 1, and the opening and closing mechanism 3 includes a cylinder 302 located in the center of the valve body 1, and a baffle ring 301 connected to the inner wall of the valve body 1 is slidingly provided on the outside of the cylinder 302. The baffle ring 301 divides the interior of the valve body 1 into an upper chamber and a lower chamber, and a sealing ring is provided at the sliding connection between the cylinder 302 and the baffle ring 301 to prevent water leakage.

[0041] like Figure 1-Figure 3 As shown, a water inlet pipe 7 is installed on the side of the valve body 1, and a secondary pipe 9 is installed on the side of the water inlet pipe 7, which is connected to the valve body 1 at an angle downward, to connect the water inlet pipe 7 with the water source, and water enters the lower cavity in the valve body 1 through the water inlet pipe 7 and the secondary pipe 9.

[0042] like Figure 1-Figure 3 As shown, a through hole aligned with the water inlet pipe 7 is opened on the side of the valve body 1, and a water outlet pipe 8 is installed at the end of the through hole. A one-way valve 10 is provided in the water outlet pipe 8. The water outlet pipe 8 is connected to the output pipe, and the water in the upper cavity is discharged into the output pipe through the water outlet pipe 8. At the same time, the one-way valve 10 is used to prevent the water in the output pipe from being discharged back.

[0043] like Figure 1 and Figure 2 As shown, it also includes a detection mechanism 2, which includes an upper shell 201 installed on the upper side of the valve body 1 and connected thereto, a diaphragm 202 is provided at the port of the upper shell 201, a vertical rod 203 is installed at the center of the lower side of the diaphragm 202, and a spring 1 204 is provided above the diaphragm 202. When the water pressure in the upper chamber is low, the spring 1 204 stretches and presses the diaphragm 202 and the vertical rod 203 downward. When the water pressure becomes high, the spring 1 204 is compressed through the diaphragm 202 and the vertical rod 203 is driven to rise at the same time.

[0044] like Figure 2 As shown, a threaded hole is provided at the center of the upper side of the upper shell 201, in which a screw 205 which is adapted thereto and whose lower end is rotatably connected to the pressure plate 206 is provided. A knob 207 is installed on the upper end of the screw 205, and a pressure plate 206 which is slidably connected to the inner wall of the upper shell 201 is rotatably installed on the lower end. The screw 205 is rotated by rotating the knob 207 to drive the screw 205 and the pressure plate 206 to descend, and the descending pressure plate 206 compresses the spring 204, thereby increasing the preload force of the spring 204, and vice versa.

[0045] It should be noted that the preload force of spring 1 204 is adjusted according to the amount of water replenishment required. If a high amount of water replenishment is required, the preload force is increased, and vice versa, so that the distribution of water replenishment can be adjusted. At the same time, a transparent window is also provided on the side of the upper shell 201 to facilitate the staff to observe the current compression amount of spring 1 204.

[0046] In summary, water enters the lower chamber in the valve body 1 through the water inlet pipe 7 and the auxiliary pipe 9, and then the water in the upper chamber is discharged into the output pipe through the water outlet pipe 8. At the same time, the one-way valve 10 is used to prevent the water in the output pipe from being discharged back. The screw rod 205 is rotated by the knob 207 to drive the screw rod 205 and the pressure plate 206 to descend. The descending pressure plate 206 compresses the spring 204, increasing the preload force of the spring 204. When the water pressure in the upper chamber is lower than the preload force, the spring 204 extends and presses down the diaphragm 202, driving the vertical rod 203 to descend. When the water pressure in the upper chamber is greater than the preload force after water replenishment, the spring 204 is compressed through the diaphragm 202 and the vertical rod 203 is driven to rise at the same time.

[0047] like Figure 4-Figure 6 As shown, a plurality of rectangular openings 303 evenly distributed in the circumferential direction are provided on the side of the cylinder 302. The lower end of the vertical rod 203 extends into the cylinder 302 and is installed with a turbine 304. A telescopic rod 308 is installed at the center of the lower side of the turbine 304. The telescopic rod 308 can only slide axially, and its main axis and secondary axis cannot rotate relative to each other. When replenishing water, the water in the lower chamber enters the cylinder 302 through the opening 303, and then rises into the upper chamber. At the same time, the rising water drives the turbine 304 to rotate, which drives the telescopic rod 308 to rotate, reducing the impact force of the water.

[0048] like Figure 5-Figure 6 As shown, an inner retaining ring 307 is slidingly provided on the inner wall of the cylinder 302, and a connecting assembly is provided between the inner retaining ring 307 and the turbine 304. The connecting assembly includes a hollow tube 305 which is sleeved on the telescopic rod 308 and the upper end of which is rotatably connected to the turbine 304. A plurality of fixed rods 306 connected to the inner retaining ring 307 and evenly distributed in the circumference are installed on the side of the hollow tube 305. The inner retaining ring 307 is used to close all openings 303. When the water pressure in the upper chamber decreases and the vertical rod 203 descends, the inner retaining ring 307 will be driven to descend through the hollow tube 305 and the fixed rod 306, so that the opening 303 is opened.

[0049] At the same time, the descending inner retaining ring 307 allows the opening range of the opening 303 to gradually expand, limiting the water inlet flow rate, steadily increasing the flow rate, avoiding a sudden pressure rise when the water pressure in the upper chamber does not reach the predetermined value and compressing the spring 1 204, while also avoiding the occurrence of instantaneous high impact force directly impacting the diaphragm 202.

[0050] like Figure 5 and Figure 6 As shown, a lower retaining ring 309 is installed near the bottom of the cylinder 302 , the lower end of which is connected to the inner bottom surface of the valve body 1 , and the lower retaining ring 309 is used to isolate the gap between the cylinder 302 and the inner bottom surface of the valve body 1 .

[0051] like Figure 4 and Figure 7As shown, the friction mechanism 4 includes a housing 401 installed at the center of the lower side of the valve body 1, a bimetallic strip 402 is provided in the housing 401, and the lower end of the telescopic rod 308 extends into the housing 401 and is installed with a rotating block 407 that contacts the bimetallic strip 402. The rotating telescopic rod 308 drives the rotating block 407 to rotate, and the surface friction of the bimetallic strip 402 causes the rotating block 407 to apply a reverse damping force to the turbine 304, thereby further reducing the impact force of the water.

[0052] When the water pressure in the upper chamber exceeds the preload force of spring 1204, spring 1204 is compressed through diaphragm 202, driving inner retaining ring 307 to rise and close opening 303, stopping water supply to the upper chamber. When the water pressure in the upper chamber decreases and vertical rod 203 is lowered, inner retaining ring 307 is driven to fall through hollow tube 305 and fixed rod 306. The falling inner retaining ring 307 gradually expands the opening range of opening 303, limits the water inlet flow rate, and steadily increases the flow rate. Water in the lower chamber enters cylinder 302 through opening 303, and then rises into the upper chamber. At the same time, the rising water drives turbine 304 to rotate, driving telescopic rod 308 to rotate, reducing the impact force of water.

[0053] like Figure 6 and Figure 7 As shown, the middle portion of the lower side of the bimetallic strip 402 is connected to the inner wall of the shell 401, and the adjacent sides of the bimetallic strip 402 and the rotating block 407 are coated with a friction coating (graphite coating). The thermal expansion coefficient of the upper metal strip of the bimetallic strip 402 is smaller than that of the lower metal strip. When the rotating block 407 rotates relative to the bimetallic strip 402, the friction coating in contact with the adjacent sides generates heat during rotation. For example, after half an hour of rotation, the heat provided by it reaches the bending heat of the bimetallic strip 402. Since the thermal expansion coefficient of the upper metal strip of the bimetallic strip 402 is smaller than that of the lower metal strip, the lower metal strip expands more and the upper metal strip expands less, causing the bimetallic strip 402 to bend toward the upper metal strip with a smaller thermal expansion coefficient. At the same time, due to the limitation of the rotating block 407, the bimetallic strip 402 can only bend upward at both ends.

[0054] The user can also spray friction coatings with different friction coefficients according to specific needs to change the time it takes for the bimetallic strip 402 to bend.

[0055] like Figure 7 and Figure 8As shown, two mouth-shaped frames 403 are symmetrically slidably provided inside the shell 401 and are sleeved on the bimetallic strip 402. The two inner side surfaces of the mouth-shaped frames 403 are provided with strip grooves 405. A slider 406 connected to the lower metal sheet of the bimetallic strip 402 is slidably provided in each strip groove 405. When the bimetallic strip 402 bends upward, its two ends will be close to each other, thereby driving the two sliders 406 to be close to each other, pulling the two mouth-shaped frames 403 closer to each other.

[0056] like Figure 8 As shown, a limit block 404 extending to the outside of the shell 401 is installed on the side of the mouth-shaped frame 403, and a bevel is set on the upper side of the limit block 404. The mouth-shaped frames 403 approaching each other will drive the limit block 404 to retract into the shell 401, and at the same time, squeezing the bevel of the limit block 404 will also squeeze the limit block 404 into the shell 401.

[0057] like Figure 6 and Figure 9 As shown, a closing mechanism 5 is also provided, which includes an outer retaining ring 505 slidably provided on the outside of the cylinder 302 . When the outer retaining ring 505 rises to the same height as the openings 303 , all openings 303 can be closed.

[0058] like Figure 8 As shown, the closing mechanism 5 also includes a driving assembly, which allows the outer retaining ring 505 to cover and close all openings 303 when the bimetallic strip 402 is bent. The driving assembly includes a sealing plate 501 installed on the side of the outer retaining ring 505 and below the connection between the auxiliary pipe 9 and the valve body 1. A connecting rod 502 is installed on the lower side of the sealing plate 501. A compressed spring 2 503 is sleeved on the connecting rod 502 between the sealing plate 501 and the inner bottom surface of the valve body 1. When the spring 2 503 rebounds, it will drive the outer retaining ring 505 to rise through the sealing plate 501, and the sealing plate 501 is used to block the components below it from water. At the same time, when the outer retaining ring 505 rises to its highest point, the sealing plate 501 is still located below the connection between the auxiliary pipe 9 and the valve body 1.

[0059] A sealing ring is also provided on the outside of the sealing plate 501 to seal the gap between the sealing plate 501 and the inner wall of the valve body 1 .

[0060] like Figure 6 and Figure 9 As shown, the lower end of the connecting rod 502 extends to the outside of the valve body 1 and is installed with a rectangular block 504. The limit block 404 limits the rectangular block 504 on the same side. When the limit block 404 retracts into the shell 401, the limit on the rectangular block 504 will be released, allowing the compressed spring 2 503 to rebound.

[0061] At the same time, when the blockage of the opening 303 is released, the two rectangular blocks 504 are pulled down manually, driving the outer retaining ring 505 to move and release the blockage of the opening 303. The descending sealing plate 501 compresses the spring 2 503, and at the same time uses the rectangular block 504 to squeeze the inclined surface of the limit block 404 on the same side, allowing each limit block 404 to enter the shell 401 and compress the bimetallic strip 402 completely. When the rectangular block 504 moves and is below the limit block 404, the limit block 404 is no longer limited, allowing the bimetallic strip 402 to rebound and restore its position, thereby limiting the rectangular block 504.

[0062] It should be noted that a detachable protective shell (not shown in the figure) is provided on the lower side of the valve body 1 outside the friction mechanism 4 , and the protective shell is used to protect the friction mechanism 4 and the closing mechanism 5 outside the valve body 1 .

[0063] In summary, when there is a leak in the external output pipeline connected to the water outlet pipe 8, the upper chamber will be constantly replenished with water, so that the pressure in the upper chamber is always low, forcing the opening 303 to be always open, and the turbine 304 will rotate for a long time, driving the rotating block 407 to rotate, and utilizing the friction coating in contact with the adjacent side of the bimetallic strip 402 to generate heat during rotation. After rotating for half an hour, the heat provided reaches the bending heat of the bimetallic strip 402, and then the bimetallic strip 402 bends upward, causing the two limit blocks 404 to retract into the shell 401, releasing the limit on the rectangular block 504, and the spring 2 503 rebounds to drive the outer retaining ring 505 to rise and close all openings 303, avoiding waste caused by continuous water replenishment. Example 2:

[0064] Based on the first embodiment, Figure 10 As shown, it also includes an adjustment mechanism 6 located in the protective shell. The adjustment mechanism 6 includes a screw rod 601 rotatably installed at the center of the lower side of the shell 401. The lower end of the screw rod 601 is installed with a knob 605. The user can manually rotate the screw rod 601 through the knob 605.

[0065] like Figure 10 As shown, a threaded barrel 602 that matches the screw rod 2 601 is sleeved thereon, a strip plate 603 is installed on the side of the threaded barrel 602, and two round rods 604 that extend into the valve body 1 and are connected to the cylinder 302 are symmetrically installed on the upper side of the strip plate 603. The rotating screw rod 2 601 drives the threaded barrel 602 to rotate, and the cylinder 302 is pulled down through the strip plate 603 and the round rod 604. The height of the opening 303 on the cylinder 302 is adjusted, and the opening range of the opening 303 when the inner retaining ring 307 is adjusted to the lowest level.

[0066] like Figure 11As shown, an observation rod 606 is installed on the lower side of the valve body 1 and passes through the strip plate 603 and is slidably connected to it. Scale lines are set on the side of the observation rod 606. The rising and falling strip plate 603 slides on the observation rod 606, and the user can observe the position of the strip plate 603 conveniently through the scale lines.

[0067] In summary, the user can manually rotate the screw 2 601 through the knob 2 605. The rotating screw 2 601 drives the threaded cylinder 602 to rotate, and the cylinder 302 is pulled down through the strip plate 603 and the round rod 604. The height of the opening 303 on the cylinder 302 is adjusted, and the opening range of the opening 303 when the inner retaining ring 307 is adjusted to the lowest point is adjusted. The user can adjust the opening range of the opening 303 according to cold water or hot water to maintain the same flow rate (cold water has a large flow resistance, and a small opening can maintain a sufficient flow rate, while hot water flows more smoothly and the opening needs to be enlarged to maintain a high flow rate).

[0068] Specifically, the present application also discloses a method for using a water replenishment valve with adjustable water replenishment amount distribution, the method steps are as follows:

[0069] S1. Structural installation. Install the device at the predetermined position. Specifically, connect the water inlet pipe 7 to the water source, and the water outlet pipe 8 to the output pipe. Previously, due to the lack of water pressure in the upper cavity, the spring 204 stretched and drove the inner retaining ring 307 to descend, opening all the openings 303. After that, the water source entered the lower cavity in the valve body 1 through the water inlet pipe 7 and the auxiliary pipe 9, and then entered the upper cavity through the opening 303, and entered the external output pipeline system through the water outlet pipe 8. When the water pressure in the upper cavity exceeds the preload of the spring 204, the diaphragm 202 compresses the spring 204 and drives the inner retaining ring 307 to rise and close the opening 303, stopping the water supply to the upper cavity. The one-way valve 10 prevents the water in the output pipe from being discharged back into the valve body 1. The preload of the spring 204 is adjusted according to the required water replenishment amount. If a high water replenishment amount is required, the preload is increased, and vice versa.

[0070] S2. Water replenishment work. The device is used to replenish water in the upper chamber when the water pressure decreases. Specifically, the inner retaining ring 307 is used to close all openings 303. When the water pressure in the upper chamber decreases, the spring 1 204 extends and drives the spring 1 204 to descend through the diaphragm 202, and drives the inner retaining ring 307 to descend through the hollow tube 305 and the fixed rod 306. The descending inner retaining ring 307 allows the opening range of the opening 303 to gradually expand and open. The water in the lower chamber enters the cylinder 302 through the opening 303, and then rises into the upper chamber. At the same time, the rising water drives the turbine 304 to rotate, reducing the impact force of the water.

[0071] S3. Water replenishment is completed. Water replenishment is completed after the water pressure in the upper chamber returns to normal. Specifically, water continues to flow into the upper chamber, causing the water pressure to increase. Then, the diaphragm 202 compresses the spring 1 204 while driving the vertical rod 203 to rise. The rising vertical rod 203 drives the inner retaining ring 307 to rise through the hollow tube 305 and the fixed rod 306 until all openings 303 are closed, and then the water replenishment can be stopped.

[0072] S4. Water leakage protection. Stop replenishing water after the output pipeline has been leaking for a long time. Specifically, when the output pipeline is leaking, it will cause low pressure in the upper chamber, so that the opening 303 is always open, forcing the turbine 304 to rotate for a long time, driving the rotating block 407 to rotate, and utilizing the friction coating in contact with the adjacent side of the bimetallic strip 402 to generate heat during rotation. After half an hour of rotation, the heat it provides reaches the bending heat of the bimetallic strip 402, and then the bimetallic strip 402 bends upward, causing the two limit blocks 404 to retract into the shell 401, releasing the limit on the rectangular block 504, and the spring 2 503 rebounds to drive the outer retaining ring 505 to rise and close all openings 303, avoiding waste caused by continuous water replenishment.
