Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a dual-pressure regulating device and water treatment equipment. Background Art

[0002] With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If sewage is not completely purified and discharged directly, it will re-enter the earth's water cycle system. In addition to destroying the ecological environment, sewage will also enter the human body and affect human health. Therefore, sewage needs to be treated before it is discharged.

[0003] For example, a Chinese patent with authorization announcement number CN112723445B discloses a sewage treatment agent spreading device for sewage treatment, including a support platform, groove blocks are fixedly installed on the left and right sides of the top of the support platform, a connecting column is fixedly installed on the top of the groove block, a dumping component is fixedly and movably connected to the front of the connecting column, a power source is fixedly installed on the opposite side of the top of the two connecting columns, an inverted arc circle is fixedly installed on the opposite side of the two groove blocks, cross bars are fixedly installed on the left and right sides of the inner wall of the inverted arc circle, a square platform is fixedly installed on the bottom end of the inner wall of the inverted arc circle, the inner wall of the square platform is movably connected with a stirring fan blade, the left side of the stirring fan blade is movably connected with a spreading component, and the right side of the spreading component is movably connected with a track disk.

[0004] However, the above-mentioned prior art still has some problems. Although the above-mentioned prior art can change the spraying area of ​​the agent by adjusting the position of the dosing device, there will be a certain unsprayed area between the changed area and the initial spraying area, and the diffusion of the agent requires a certain amount of time, which will cause the sewage treatment efficiency to be low.

In order to improve the treatment efficiency of sewage, a medicine spraying unit is provided in the device. At least two regulating components are provided in the medicine spraying unit. The driving wheel serves as the driving source of one of the regulating components, and the driving source of the other regulating component is the driven gear. Since the diameter of the driving gear is larger than that of the driven gear, the diameter of the driving wheel is smaller than that of the driving gear, and the driving wheel and the driving gear are connected by a driving shaft, so that the driving wheel and the driving gear have the same rotation speed. Due to the diameter difference between the driving gear and the driven gear, and between the driving wheel and the driving gear, there is a difference in the adjustment speed between the two regulating components when driving the regulating components. Specifically, the regulating component connected to the driving wheel has a slower adjustment rate, while the regulating component connected to the driven gear has a faster adjustment rate. The change value of the nozzle height in the regulating component with a faster adjustment rate is greater than the change value of the nozzle height in the regulating component with a slower adjustment rate. Thus, the spraying area of the nozzle in the regulating component with a slower adjustment rate is located between the initial spraying area and the spraying area of the nozzle in the regulating component with a faster adjustment rate, avoiding a large area between the adjusted spraying area and the initial area, reducing the diffusion time of the medicine, and improving the sewage treatment efficiency.

Detailed implementation manners

[0050] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings of the specification.

[0051] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0052] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or selectively exclusive of other embodiments.

[0053] The present invention discloses a dual-pressure regulating device and a water treatment device. Refer to Figures 1 - 10 , including:

[0054] A sedimentation tank 1 for holding sewage and serving as a reaction vessel for sewage and chemicals; a chemical spraying unit 6 located above the sedimentation tank 1 for spraying chemicals into the sedimentation tank 1; a displacement unit 2 for connecting the sedimentation tank 1 and the chemical spraying unit 6 to adjust the horizontal position of the chemical spraying unit 6 and change the chemical spraying area. The chemical spraying unit 6 includes a connecting seat 61 fixedly connected to the displacement unit 2, a driving mechanism arranged on the connecting seat 61, two adjusting components 69 connected to the driving mechanism, and a plurality of nozzles 66 arranged on the adjusting components 69. Driven by the same driving mechanism, the moving distance of the spraying area of the nozzles 66 in one adjusting component 69 is different from that of the spraying area of the nozzles 66 in the other adjusting component 69, so as to adjust the spraying area of the nozzles 66 and complete the chemical addition work. The displacement unit 2 is a two-dimensional displacement platform, which is a prior art and is arranged on the length and width surfaces of the sedimentation tank 1 to adjust the position of the chemical spraying unit 6, thereby adjusting the chemical spraying area of the chemical spraying unit 6.

[0055] When sewage in the sedimentation tank 1 needs to be treated, at this time, the chemical spraying unit 6 can inject chemicals into the sewage in the sedimentation tank 1. The chemicals react with metal ions or impurities in the sewage or flocculate, so as to complete the sewage treatment work. At the same time, in order to avoid too high chemical concentration in a local area, which may lead to too slow chemical diffusion speed, a displacement unit 2 is provided in this device. The displacement unit 2 drives the chemical spraying unit 6 to move, thereby adjusting the chemical spraying area of the chemical spraying unit 6, avoiding too high chemical concentration in a local area of the sewage, and avoiding waste of flocculant when using flocculant.

[0056] The driving mechanism includes a driving motor 62 fixedly installed on the connecting seat 61, a driving gear 63 arranged at the output end of the driving motor 62, a transmission gear 64 meshing with the driving gear 63. A driving shaft 67 penetrating the connecting seat 61 is arranged on the transmission gear 64, a driving wheel 68 sleeved on the driving shaft 67, a driven gear 65 meshing with the transmission gear 64, two transmission shafts 611 arranged on the connecting seat 61, a transmission wheel 610 sleeved on one of the transmission shafts 611, and a transmission belt for connecting the driving wheel 68 and the transmission wheel 610. The adjusting component 69 is connected to the transmission shaft 611, and the driven gear 65 is sleeved on the other transmission shaft 611. The diameter of the transmission gear 64 is larger than that of the driven gear 65, and the diameter of the driving wheel 68 is smaller than that of the transmission wheel 610. Through the cooperation of the driving motor 62 and the transmission belt, when the driving motor 62 works, the adjusting component 69 can move to adjust the chemical spraying area of the nozzles 66. At the same time, the adjustment rates of the two adjusting components 69 are different, so that the spraying area of the nozzles 66 on one adjusting component 69 is located between the initial spraying area and the spraying area of the nozzles 66 on the other adjusting component 69.

[0057] To make the adjusting assembly 69 work, the driving motor 62 starts to work at this time. The moving driving motor 62 can drive the driving gear 63 to rotate. Then the moving driving gear 63 can drive the transmission gear 64 to rotate. The moving transmission gear 64 can drive the driving shaft 67 to rotate, so as to drive the driving wheel 68 to move. At the same time, the rotating transmission gear 64 can drive the driven gear 65 to rotate. Then the moving driven gear 65 can drive one of the transmission shafts 611 to rotate. And the moving driving wheel 68 can drive the transmission wheel 610 to rotate through the arranged transmission belt, so that the transmission wheel 610 can drive the other transmission shaft 611 to rotate, and then can drive the two adjusting assemblies 69 to work respectively, adjust the position of the spray head 66, and then change the spraying area of the medicament;

[0058] In a further embodiment, the transmission wheel 610 serves as the driving source of one of the adjusting assemblies 69, and the driving source of the other adjusting assembly 69 is the driven gear 65. Since the diameter of the transmission gear 64 is larger than the diameter of the driven gear 65, the diameter of the driving wheel 68 is smaller than the diameter of the transmission wheel 610, and at the same time, the driving wheel 68 and the transmission gear 64 are connected through the arranged driving shaft 67, so that the driving wheel 68 and the transmission gear 64 have the same rotational speed. Due to the diameter differences between the above-mentioned transmission gear 64 and the driven gear 65, and between the driving wheel 68 and the transmission wheel 610, when driving the adjusting assembly 69 to move, there is a difference in the adjustment speed between the two adjusting assemblies 69. Specifically, the adjusting assembly 69 connected to the transmission wheel 610 has a slower adjustment rate, while the adjusting assembly 69 connected to the driven gear 65 has a faster adjustment rate. The height change value of the spray head 66 in the adjusting assembly 69 with a faster adjustment rate is greater than the height change value of the spray head 66 in the adjusting assembly 69 with a slower adjustment rate. Then the spraying area of the spray head 66 in the adjusting assembly 69 with a slower adjustment rate is located between the initial spraying area and the spraying area of the spray head 66 in the adjusting assembly 69 with a faster adjustment rate, avoiding too large an area between the adjusted spraying area and the initial area, reducing the diffusion time of the medicament, and improving the efficiency of sewage treatment;

[0059] The adjustment component 69 cooperates with the displacement unit 2. It can not only adjust the horizontal position of the nozzle 66 but also adjust the height of the nozzle 66. Thus, when the displacement unit 2 is not working, the increase in the height of the nozzle 66 can increase the spraying distance. At the same time, since the increase in the height of the nozzle 66 will cause a change in the incident angle when the agent enters the sewage. When the incident angle of the agent is small, by the operation of the adjustment component 69, the height of the nozzle 66 is changed to adjust the injection angle of the agent to avoid too small an incident angle. On the contrary, when the incident angle is too large, although the agent can quickly reach the bottom of the sewage, the diffusion range in the horizontal direction may be relatively narrow. Therefore, the displacement unit 2 starts to work to adjust the position of the nozzle 66 so that the nozzle 66 can move horizontally on the sewage surface, thereby expanding the injection range of the agent and ensuring the diffusion efficiency of the agent.

[0060] The adjustment component 69 includes two cam disks 692 symmetrically arranged on the transmission shaft 611, a first support seat 696 fixedly arranged on the connecting seat 61, a movable rod 697 movably connected to the first support seat 696, a control rod 695 sleeved on the movable rod 697, ball joints 693 respectively arranged at the eccentric positions of the control rod 695 and the cam disks 692, a fish-eye joint 694 for connecting the ball joints 693, and an adjustment plate 698 connected to the control rod 695; the nozzle 66 is arranged on the adjustment plate 698; when the driving mechanism starts to work, the moving driving mechanism can drive the transmission shaft 611 to rotate, then the moving transmission shaft 611 can drive the cam disks 692 to rotate, then the moving cam disks 692 can drive the ball joints 693 thereon to move, and then the moving ball joints 693 can drive another ball joint 693 to move through the arranged fish-eye joint 694, so as to drive the control rod 695 to move, making the control rod 695 rotate around the movable rod 697 as the rotation axis, thereby changing the angle between the adjustment plate 698 and the connecting seat 61, changing the linear distance between the nozzle 66 on the adjustment plate 698 and the connecting seat 61 and the height from the sewage level surface, and further completing the adjustment work of the position of the nozzle 66 to ensure the smooth progress of the agent spraying work.

[0061] A dual-pressure regulating device, including a dual-pressure regulating valve 3, which is used to control the fluid pressure so that the fluid can pass through with different pressure set values, enabling sewage to be discharged to a predetermined area for sewage treatment; a connecting valve, connected to the water inlet end of the dual-pressure regulating valve 3; a liquid injection unit 4, connected to the connecting valve, used to inject a cleaning agent into the valve body of the dual-pressure regulating valve 3 so that the cleaning agent can react with the scale on the inner wall of the valve body of the dual-pressure regulating valve 3; a connecting pipe 5, connected to the water inlet end of the dual-pressure regulating valve 3, used to inject sewage into the sedimentation tank 1; by setting the dual-pressure regulating valve 3, the water flow rate of the sewage entering the sedimentation tank 1 can be adjusted, thereby avoiding the excessive water flow rate that may cause the sewage to impact the bottom of the sedimentation tank 1, resulting in the overturning of the sediment.

[0062] In a further embodiment, during the process of treating the sewage in the sedimentation tank 1, the dual-pressure regulating valve 3 stops the sewage transportation work. At this time, the sewage will remain in the dual-pressure regulating valve 3. During this process, reactions may occur between the impurities or some other metal ions or non-metal ions in the sewage, which is likely to form precipitates in the valve body of the dual-pressure regulating valve 3, thereby affecting the water outlet efficiency of the dual-pressure regulating valve 3. At the same time, it will also cause the dual-pressure regulating valve 3 to get stuck, resulting in its inability to open and close normally. Moreover, excessive precipitation will also change the flow channel shape and the flow-through area inside the valve, causing inaccurate flow control.

[0063] To solve the above problems, a liquid injection unit 4 is provided in this device. The liquid injection unit 4 includes a medicine injection tank 41, a water outlet assembly 42, a water inlet assembly 43, a water inlet pipe 44, and a water outlet pipe 45; the medicine injection tank 41 is arranged on the dual-pressure regulating valve 3 and is used for storing the cleaning agent; the water inlet pipe 44 and the water outlet pipe 45 are respectively connected to the medicine injection tank 41. The water inlet pipe 44 is used to transport the cleaning agent into the medicine injection tank 41, and the water outlet pipe 45 is used to transport the cleaning agent in the medicine injection tank 41 into the valve body of the dual-pressure regulating valve 3; the water inlet assembly 43 and the water outlet assembly 42 are respectively located inside the medicine injection tank 41. Among them, the water inlet assembly 43 is connected to the water inlet pipe 44, the water outlet assembly 42 is connected to the water outlet pipe 45. The water inlet assembly 43 is used to control the input amount of the cleaning agent, and the water outlet assembly 42 is used to control the output amount of the cleaning agent; by setting the liquid injection unit 4, the cleaning agent can be injected into the valve body. By injecting the cleaning agent, the cleaning agent can react with the scale in the valve body, thereby removing the attached scale and reducing the generation of scale.

[0064] The water inlet assembly 43 includes a base 433 connected to the water outlet end of the water inlet pipe 44, a first support pipe 435 connected to the base 433, a water delivery pipe 431 disposed inside the first support pipe 435 and connected to the base 433, a second support pipe 434 sleeved on the first support pipe 435, a fixed seat 437 connected to the second support pipe 434, a water outlet seat 432 disposed on the water delivery pipe 431 and located inside the fixed seat 437, a floating seat 436 disposed inside the fixed seat 437, and a driving portion 438 connected to the floating seat 436. A plurality of leakage holes are formed in the water outlet seat 432, and the water leakage area of the leakage holes is located in the area surrounded by the inner wall of the first support pipe 435, the inner wall of the second support pipe 434, and the outer wall of the water delivery pipe 431. A plurality of water outlet holes are provided on the base 433. One end of the water delivery pipe 431 is communicated with the water inlet pipe 44. A groove for the floating seat 436 to slide is provided on the fixed seat 437. A gasket is provided on the floating seat 436, and the gasket abuts against the water outlet end of the water delivery pipe 431. The driving portion 438 includes a floating cover 4381 sleeved on the second support pipe 434, a connecting member 4382 connected to the floating cover 4381, an adjusting rod 4383 provided on the connecting member 4382, a driving arm 4384 movably connected to the adjusting rod 4383, a movable shaft 4385 provided on the fixed seat 437, and a connecting arm 4386 movably connected to the driving arm 4384. The driving arm 4384 is movably connected to the fixed seat 437 through the movable shaft 4385. One end of the connecting arm 4386 extends into the fixed seat 437 and is connected to the floating seat 436.

[0065] When it is necessary to inject the cleaning agent into the medicine injection box 41, at this time, water can be injected into the water inlet pipe 44. Then, the cleaning agent flows along the water inlet pipe 44 and the base 433 into the water delivery pipe 431. After that, the cleaning agent moves along the length direction of the water delivery pipe 431. Then, the cleaning agent sprays out from the top of the water delivery pipe 431 and is located in the fixed seat 437. Then, the cleaning agent moves from the leakage holes on the water outlet seat 432 into the area surrounded by the inner wall of the first support pipe 435, the inner wall of the second support pipe 434, and the outer wall of the water delivery pipe 431. Then, it flows into the medicine injection box 41 through the water outlet holes on the base 433. Then, as the height of the cleaning agent in the medicine injection box 41 continuously increases, the floating cover 4381 can move on the second support pipe 434. The moving floating cover 4381 can drive the connecting member 4382 to move, thereby driving the adjusting rod 4383 to start working, and then being able to drive the driving arm 4384 to move. Since the driving arm 4384 is movably connected to the fixed seat 437 and the connecting arm 4386 is also movably connected to the driving arm 4384, during the rising process of the floating cover 4381, the connecting arm 4386 can drive the floating seat 436 close to the liquid level of the cleaning agent, so that the floating seat 436 can abut against the water outlet of the water delivery pipe 431 and stop the injection of the cleaning agent; enabling the medicine in the medicine injection box 41 to reach the established capacity. Since this device is used on the double-pressure regulating valve 3, the entire process of the above device is controlled by mechanical parts, avoiding excessive vibration during the operation of the double-pressure regulating valve 3, which may cause damage to electronic parts and result in the failure of the cleaning agent injection work.

[0066] The water outlet assembly 42 includes a limit cover 428 built in the medicine injection box 41, a support sleeve 422 located inside the limit cover 428 and sleeved on the water outlet pipe 45, a support rod 421 built in the support sleeve 422, a limit ear 426 arranged at one end of the support rod 421, a sealing gasket 427 connected to the other end of the support rod 421 and used to block the water inlet of the water outlet pipe 45, a connecting ear 423 arranged on the outer wall of the support sleeve 422, a driving rod 424 located in the connecting ear 423, and a driving handle 425 connected to the driving rod 424; a plurality of communication holes are provided on the limit cover 428; the support sleeve 422 is successively provided with a first sleeve 4221, a first transition pipe 4222, a second sleeve 4223, a second transition pipe 4224 and a third sleeve 4225 in the direction close to the water outlet pipe 45, wherein the diameters of the first sleeve 4221, the second sleeve 4223 and the third sleeve 4225 gradually increase in the direction close to the water outlet pipe 45; an extension pipe 4226 is further arranged on the inner wall of the first transition pipe 4222, the extension pipe 4226 extends in the direction close to the water outlet pipe 45, and an air cavity is formed between the outer wall of the extension pipe 4226 and the inner walls of the second sleeve 4223 and the first transition pipe 4222 for storing gas; a water inlet is further provided on the third sleeve 4225; when the injection work of the cleaning agent is required, during the injection process of the cleaning agent, due to the rising of the water surface of the cleaning agent, air will remain in the air cavity, and then the support sleeve 422 will move upward until the support sleeve 422 abuts against the limit ear 426. Then, as the water surface of the cleaning agent continues to rise, at this time, the support sleeve 422 will push the limit ear 426 to move upward, thereby driving the support rod 421 to move upward. Since a sealing gasket 427 is arranged at one end of the support rod 421, during the upward movement of the support rod 421, a gap will be generated between the sealing gasket 427 and the water outlet pipe 45, and the cleaning agent will be discharged from the water outlet pipe 45 through this gap. During the passing of the cleaning agent, the sealing gasket 427 will deform, and then the adsorption work of the sealing gasket 427 will be achieved to prevent the cleaning agent from being discharged from the water outlet pipe 45. When the discharge work is required, at this time, rotate the driving handle 425, the moving driving handle 425 drives the driving rod 424 to move, and then the moving driving rod 424 drives the connecting ear 423 to start working. At this time, the pulling force applied by the connecting ear 423 to the support sleeve 422 is greater than the adsorption force of the water flow on the sealing gasket 427, so that the sealing gasket 427 can be away from the water outlet pipe 45, and the cleaning agent can be discharged from the water outlet pipe 45, so that the cleaning agent can be transported to the double-pressure regulating valve 3, and the cleaning agent can react with the water scale at the bottom of the valve seat in the double-pressure regulating valve 3, thereby completing the cleaning work of the double-pressure regulating valve 3; during the drainage process, as the liquid level of the cleaning agent drops, then the support sleeve 422 will move toward the water outlet pipe 45, so that the sealing gasket 427 abuts against the water inlet of the water outlet pipe 45, and then the sealing work is completed, and the injection of the cleaning agent is stopped.

[0067] In a further embodiment, by using the water outlet assembly 42 in conjunction with the water inlet assembly 43, the dosage of the injected cleaning agent can be kept within a predetermined range through the above-mentioned mechanical structure without the need for a measuring instrument or a flow meter, thereby avoiding excessive or insufficient injection of cleaning agent and ensuring smooth cleaning of the dual-pressure regulating valve 3.

[0068] In a further embodiment, a second support seat 699 and a hinge rod 691 movably connected to the second support seat 699 are further provided on the connecting seat 61 , and the hinge rod 691 is connected to the adjustment plate 698 .

[0069] Working principle description: When it is necessary to treat the sewage in the sedimentation tank 1, the spraying unit 6 can inject a reagent into the sewage in the sedimentation tank 1, and the reagent reacts with the metal ions or impurities in the sewage or flocculates, thereby completing the sewage treatment work. At the same time, in order to avoid excessive concentration of the reagent in the local area, which leads to too slow diffusion of the reagent, a displacement unit 2 is provided in the device, and the displacement unit 2 drives the spraying unit 6 to move, thereby adjusting the spraying area of ​​the spraying unit 6, avoiding excessive concentration of the reagent in the local area of ​​the sewage, and avoiding waste of flocculants when using flocculants;

[0070] In order to make the adjustment component 69 work, the driving motor 62 starts to work at this time, and the moving driving motor 62 can drive the driving gear 63 to rotate, and then the moving driving gear 63 can drive the transmission gear 64 to rotate, and the moving transmission gear 64 can drive the driving shaft 67 to rotate, thereby driving the driving wheel 68 to move, and at the same time the rotating transmission gear 64 can drive the driven gear 65 to rotate, and then the moving driven gear 65 can drive one of the transmission shafts 611 to rotate, and the moving driving wheel 68 can drive the transmission wheel 610 to rotate through the set transmission belt, so that the transmission wheel 610 can drive the other transmission shaft 611 to rotate, and then can respectively drive the two adjustment components 69 to work, adjust the position of the nozzle 66, and then change the spraying area of ​​the medicine;

[0071] When the drive mechanism starts to work, the moving drive mechanism can drive the transmission shaft 611 to rotate. Then, the moving transmission shaft 611 can drive the cam disk 692 to rotate. Next, the moving cam disk 692 can drive the ball joint 693 thereon to move. Then, the moving ball joint 693 can drive another ball joint 693 to move through the provided spherical eye joint 694, thereby driving the regulating rod 695 to move. The regulating rod 695 rotates around the movable rod 697 as the rotation axis, thus changing the angle between the regulating plate 698 and the connecting seat 61, changing the linear distance between the nozzle 66 on the regulating plate 698 and the connecting seat 61 and the height from the sewage level, and further completing the adjustment work of the position of the nozzle 66 to ensure the smooth progress of the chemical injection work;

[0072] When it is necessary to inject the cleaning agent into the medicine injection tank 41, at this time, water can be injected into the water inlet pipe 44. Then, the cleaning agent flows along the water inlet pipe 44 and the base 433 into the water delivery pipe 431. After that, the cleaning agent moves along the length direction of the water delivery pipe 431. Then, the cleaning agent sprays out from the top of the water delivery pipe 431 and is located in the fixed seat 437. Then, the cleaning agent moves from the leakage holes on the water outlet seat 432 into the area enclosed by the inner wall of the first support pipe 435, the inner wall of the second support pipe 434, and the outer wall of the water delivery pipe 431. Then, it flows into the medicine injection tank 41 through the water outlet holes on the base 433. Then, as the height of the cleaning agent in the medicine injection tank 41 continuously increases, the floating cover 4381 can move on the second support pipe 434. The moving floating cover 4381 can drive the connecting member 4382 to move, thereby driving the regulating rod 4383 to start working, and then being able to drive the driving arm 4384 to move. Since the driving arm 4384 is movably connected to the fixed seat 437 and the connecting arm 4386 is also movably connected to the driving arm 4384, during the rising process of the floating cover 4381, the connecting arm 4386 can drive the floating seat 436 to approach the liquid level of the cleaning agent, so that the floating seat 436 can abut against the water outlet of the water delivery pipe 431 and stop the injection work of the cleaning agent; enabling the medicine in the medicine injection tank 41 to reach the established capacity;

[0073] When the injection of the cleaning agent is required, during the injection process of the cleaning agent, due to the rising of the water surface of the cleaning agent, air will remain in the air chamber, which will cause the support sleeve 422 to move upward until the support sleeve 422 abuts against the limit ear 426. Then, as the water surface of the cleaning agent continues to rise, the support sleeve 422 will push the limit ear 426 to move upward, thereby driving the support rod 421 to move upward. Since a sealing gasket 427 is provided at one end of the support rod 421, during the upward movement of the support rod 421, a gap will be generated between the sealing gasket 427 and the water outlet pipe 45, and the cleaning agent will be discharged from the water outlet pipe 45 through this gap. During the passage of the cleaning agent, the sealing gasket 427 will deform, thereby performing the adsorption work on the sealing gasket 427 to prevent the cleaning agent from being discharged from the water outlet pipe 45. When the discharge work is required, the driving handle 425 is rotated at this time. The moving driving handle 425 drives the driving rod 424 to move, and then the moving driving rod 424 drives the connecting ear 423 to start working. At this time, the pulling force applied by the connecting ear 423 to the support table is greater than the adsorption force of the water flow on the sealing gasket 427, so that the sealing gasket 427 can be away from the water outlet pipe 45, and the cleaning agent can be discharged from the water outlet pipe 45, enabling the cleaning agent to be transported to the double-pressure regulating valve 3. The cleaning agent can react with the water scale at the bottom of the valve seat in the double-pressure regulating valve 3, thereby completing the cleaning work of the double-pressure regulating valve 3.
