[0035] The structure of the traditional wastewater throttle valve with dual wastewater flow is that a guide plug is set at the water inlet on the basis of the traditional wastewater throttle valve. Its advantage is that it will not be flushed out by the high-pressure wastewater at the water inlet. However, its disadvantage is that when throttling, the high-pressure water will produce a large water pressure drop after passing through the guide plug, resulting in a significant reduction in the water pressure flowing into the wastewater throttle valve, resulting in a reduction in the valve port sealing force and flow conversion speed, which deteriorates the reliability of the product.

[0036] In view of this, the utility model proposes a throttle valve 10 .

[0037] The utility model provides a throttle valve 10, such as Figure 1 , Figure 2 and Figure 5As shown, it is used for water purification equipment, and is specifically arranged in the water system of the water purification equipment, wherein the throttle valve 10 of the utility model is connected to the wastewater waterway, so it can also be called a wastewater valve. The throttle valve 10 includes an inlet pipe 600 and an outlet pipe 700, and the inlet pipe 600 and the outlet pipe 700 are respectively arranged on the valve body 100. The wastewater waterway is divided into two sections, one of which is connected to the inlet pipe 600, and the other is connected to the outlet pipe 700, so the water in the wastewater waterway passes through the throttle valve 10 for throttling. The inlet pipe 600 and the outlet pipe 700 can be connected to the valve body 100, or can be integrally formed with the valve body 100, which is not specifically limited here. A throttling hole 710 for constant throttling is opened on the outlet pipe 700, and when the water flows from the inlet pipe 600 into the guide plug, it can flow out from the throttle hole 710.

[0038] Mainly, see Figure 2 The throttle valve 10 includes a valve body 100, a drive assembly 200 and a diaphragm assembly 400. A valve cavity 110 is formed in the valve body 100, wherein the valve cavity 110 is divided into a high-pressure cavity 111 and a low-pressure cavity 112 by components in the valve body 100. The water inlet pipe 600 is connected to the high-pressure cavity 111, and the water outlet pipe 700 is connected to the low-pressure cavity 112. The throttle valve 10 of the utility model is a throttle valve 10 of constant throttling. The specific type of the throttle valve 10 can be a mechanical valve or a solenoid valve. In this embodiment, the throttle valve 10 is configured as a solenoid valve. At this time, the drive assembly 200 is equivalent to a coil assembly. By energizing the coil assembly of the solenoid valve, the movement of the valve core 210 is controlled. At this time, the valve core 210 in the drive assembly 200 is equivalent to a moving iron core.

[0039] For more details, please refer to Figure 2 , wherein a separator 120 is arranged in the valve body 100, and the separator 120 is a ring platform protruding from the bottom wall 720 of the valve body 100, and a chamber is enclosed inside the separator 120, and the chamber is communicated with the water outlet pipe 700, and the diaphragm assembly 400 and the separator 120 are sealed to separate the valve cavity 110 into a high-pressure cavity 111 and a low-pressure cavity 112, wherein the low-pressure cavity 112 is located inside the cavity enclosed by the separator 120 and the diaphragm assembly 400, and the high-pressure cavity 111 is located between the separator 120 and the valve body 100. The diaphragm assembly 400 and the separator 120 are sealed by a sealing ring 500, the diaphragm assembly 400 partially extends into the separator 120, and the sealing ring 500 is located between the outer wall of the diaphragm assembly 400 and the inner wall of the separator 120. In order to better assemble the sealing ring 500 between the diaphragm assembly 400 and the separator 120, an annular groove is provided on the outer wall of the diaphragm assembly 400, and the sealing ring 500 is arranged in the annular groove, and the sealing ring 500 is partially exposed in the annular groove, and then the diaphragm assembly 400 is installed in the separator 120. Of course, an annular groove for placing the sealing ring 500 can also be provided on the inner wall of the separator 120.

[0040] like Figure 2 As shown, the driving assembly 200 mainly includes a valve core 210 seat and a valve core 210, wherein the valve core 210 seat is connected and matched with the valve body 100, and the specific connection method can be screw connection or welding, which is not specifically limited here. The valve core 210 is movably arranged in the valve core 210 seat, so the valve core 210 has a first position when the coil assembly is not energized and a second position when energized.

[0041] For further information, see Figures 4 to 6 Considering that the guide plug originally arranged in the water inlet pipe 600 will affect the overall high-pressure environment in the throttle valve 10, thereby reducing the sealing performance of the valve port 413a, in an embodiment of the utility model, the guide plug is arranged in the water outlet pipe 700, so as not to affect the high-pressure environment inside the throttle valve 10.

[0042] The technical solution of the utility model adopts the method of setting the guide plug 300 in the outlet pipe 700 so that the water pressure flowing into the wastewater throttle valve 10 will not be reduced, thereby ensuring the better sealing of the valve port 413a and the higher flow conversion speed of the throttle valve 10, and improving the reliability of the throttle valve 10.

[0043] In one embodiment, see Figure 2 When the throttle valve 10 opens the single-flow throttling mode, the valve core 210 presses the diaphragm assembly 400 against the partition 120; when the throttle valve 10 opens the dual-flow throttling mode, the diaphragm assembly 400 is separated from the partition 120.

[0044] After the throttle valve 10 is installed in the water inlet system, there are two operating modes, one is a single-flow throttling mode, that is, a mode in which throttling is performed only through the throttling hole 710, and the other is a dual-flow throttling mode, that is, the throttle valve 10 throttles through both the throttling hole 710 and the guide plug. When the throttle valve 10 is in the single-flow throttling mode, the throttle valve 10 is not powered, and the valve core 210 is in the first position, the valve core 210 presses against the diaphragm assembly 400, and at the same time, the diaphragm assembly 400 is also affected by the high pressure of the chamber between it and the coil assembly to press against the partition 120, so at this time, the water flow in the high-pressure chamber 111 can only flow out through the throttling hole 710 on the outlet pipe 700. When the throttle valve 10 is in the dual-flow throttling mode, the throttle valve 10 is energized, and under the influence of the coil assembly, the valve core 210 moves in the direction away from the diaphragm assembly 400. At this time, the valve core 210 is in the second position. At this time, the diaphragm assembly 400 is separated from the partition 120 under the influence of the high-pressure chamber 111, so that the water flow can flow into the low-pressure chamber 112 in the partition 120, and then flow from the water outlet 121 through the throttling channel 310 in the guide plug 300 into the water outlet 700, and the throttling hole 710 can still throttle. The single-flow throttling mode and the dual-flow throttling mode can meet the different throttling flow requirements of the equipment using the throttle valve 10.

[0045] In one embodiment, see Figure 4 and Figure 6 The guide plug and the inner wall of the water outlet pipe 700 are sealed together.

[0046] It should be noted that, considering that the guide plug is disposed in the outlet pipe 700, in order to ensure that the guide plug has a good throttling function, the water flowing in from the water outlet 121 can only flow out through the throttling channel 310 in the guide plug, and the guide plug is sealed with the inner wall of the outlet pipe 700. The specific sealing matching method can be sealing through a sealing ring 500.

[0047] For further information, please refer to Figure 4 and Figure 6 The water outlet pipe 700 has a pipe mouth 730 and a bottom wall 720 corresponding to the pipe mouth 730 , the guide plug includes a main body 320 , a sealing ring 500 is arranged between the main body 320 and the inner wall of the water outlet pipe 700 , and the throttling hole 710 is located between the sealing ring 500 and the pipe mouth 730 .

[0048] Specifically, the guide plug includes a main body 320, and the throttling channel 310 is arranged in the middle of the main body 320. The main body 320 is roughly cylindrical. According to the above embodiment, the guide plug and the inner wall of the outlet pipe 700 are sealed by a sealing ring 500, that is, the sealing ring 500 is located between the main body 320 and the inner wall of the water pipe to prevent the water flowing from the water outlet 121 through the outlet pipe 700 from flowing out from the gap between the guide plug and the outlet pipe 700.

[0049] In addition, considering that the sealing ring 500 seals between the guide plug and the inner wall of the outlet pipe 700, in order to ensure the normal operation of the throttling hole 710, the throttling hole 710 should be set between the sealing ring 500 and the pipe mouth 730, so that the throttling valve 10 can maintain a normal throttling mode.

[0050] Optionally, see Figure 3 and Figure 4 The guide plug further includes a limiting boss 330 disposed at one end of the main body 320 , and the limiting boss 330 can abut against the bottom wall 720 to limit the relative position of the guide plug.

[0051] It should be noted that in order to prevent the guide plug from moving toward the bottom wall 720 and causing the guide plug to be misplaced, a limiting boss 330 is provided at one end of the main body 320. When the guide plug moves slightly toward the bottom wall 720, the limiting boss 330 can abut against the bottom wall 720 to prevent the guide plug from further moving toward the bottom wall 720, thereby ensuring the relative position of the guide plug and allowing the throttling function of the throttling channel 310 to operate normally.

[0052] In one embodiment, see Figure 3 and Figure 4 The guide plug also includes a clamping portion 340 connected to the main body 320 , a deformation space 350 is hollowed out between the main body 320 and the clamping portion 340 , a clamping platform 341 is provided at one end of the clamping portion 340 , and the clamping platform 341 is clamped to the outer edge of the water outlet 121 .

[0053] Specifically, the flow guide plug also includes a clamping portion 340 connected to the main body 320, and the clamping portion 340 is used to fix the flow guide plug at the water outlet 121, wherein the main body 320 and the clamping portion 340 are hollowed out to form a deformation space 350. It should be noted that in the process of installing the flow guide plug, the flow guide plug is inserted into the water outlet pipe 700 from the pipe mouth 730, and its clamping portion 340 is deformed toward the main body 320 in the water outlet pipe 700. When the flow guide plug is close to the water outlet 121, the clamping platform 341 at one end of the clamping portion 340 is clamped and matched with the outer edge of the water outlet 121, thereby fixing the relative position of the flow guide plug.

[0054] In one embodiment, see Figure 3The clamping platform 341 has a contact surface 341 a that conflicts with the outer edge of the water outlet 121 , and the contact surface 341 a is arranged in an arc surface and matches the outer edge of the water outlet 121 .

[0055] It should be noted that the card platform 341 has a contact surface 341a that abuts against the water outlet 121. When the throttle valve 10 is in the dual-flow throttling mode, the guide plug will be subjected to a large water pressure. In order to ensure that the guide plug will not shake easily when subjected to a large water pressure, the contact surface 341a is set to an arc surface to match the outer edge of the water outlet 121, thereby improving the stability of the guide plug.

[0056] In one embodiment, see Figure 3 , the guide plug is integrally formed.

[0057] The clamping portion 340, the main body 320 and the limiting boss 330 may be connected by welding or gluing. In the present embodiment, the guide plug is integrally formed, so this method is simple to form and can reduce the manufacturing process of the guide plug.

[0058] In one embodiment, see Figures 7 to 9 The diaphragm assembly 400 includes a diaphragm bracket 410 and a diaphragm body 420. A limiting column 411 is arranged in the middle of the diaphragm bracket 410. A limiting groove 411a is arranged on the periphery of the limiting column 411. A center hole 421 is arranged in the diaphragm body 420. The limiting column 411 passes through the center hole 421 to limit the diaphragm body 420 in the limiting groove 411a.

[0059] The diaphragm support 410 is used to support the diaphragm body 420. The diaphragm body 420 is generally made of rubber material, and the diaphragm support 410 is made of plastic material. The diaphragm body 420 is provided with a limiting groove 411a on the limiting column 411. Since the diaphragm body 420 is made of rubber material and has a strong deformation ability, it can first be deformed and expanded to be sleeved on the limiting column 411, moved into the limiting groove 411a, and then contracted and restored to be limited in the limiting groove 411a.

[0060] In one embodiment, Figures 7 to 9The diaphragm body 420 includes a sealing portion 422, a deformation portion 423 and a pressing portion 424 which are connected in sequence. A sleeve 230 is arranged in the valve core 210 seat, and the valve core 210 is located in the sleeve 230. The sealing portion 422 is sealed and connected with the sleeve 230 to separate the high-pressure chamber 111 into a first chamber 111a and a second chamber 111b. The diaphragm bracket 410 is provided with a connecting hole 412b, and the connecting hole 412b is used to connect the first chamber 111a and the second chamber 111b. When the throttle valve 10 is in the dual-flow throttling mode, the deformation portion 423 is deformed by the water pressure to separate the diaphragm assembly 400 from the partition 120.

[0061] Specifically, the diaphragm body 420 is integrally formed, wherein the diaphragm body 420 comprises a sealing portion 422, a deformation portion 423 and a pressing portion 424 from its periphery to the center, wherein the sealing portion 422 protrudes from the pressing portion 424, and the sealing portion 422 is used to seal with the sleeve 230 in the valve core 210 seat to fix the relative position of the periphery of the diaphragm body 420, wherein a deformation portion 423 is arranged between the sealing portion 422 and the pressing portion 424, and the deformation portion 423 is arranged in the shape of the letter n, so that when the diaphragm body 420 is subjected to a large water pressure impact, the deformation portion 423 is deformed, so that the diaphragm body 420 is separated from the partition 120. Among them, when the drive assembly 200 is not powered on, the valve core 210 presses against the diaphragm assembly 400, and then presses the pressing part 424 against the partition 120. When the coil assembly is powered on, the valve core 210 moves toward the side away from the diaphragm assembly 400, and the diaphragm body 420 is subjected to a large water pressure impact, and its deformation part 423 is deformed by force, so that the pressing part 424 is separated from the partition 120, so that a flushing channel is formed between the diaphragm body 420 and the diaphragm assembly 400, so that a large amount of raw water can enter the outlet section from the flushing channel, and when the raw water passes through the flushing channel, it can also pass through the throttling channel 310 to flush the dirt in the throttling channel 310 to prevent the throttling channel from being blocked.

[0062] Please refer to the figure Figures 7 to 9It should be noted that the high-pressure chamber 111 is divided into a first chamber 111a and a second chamber 111b, wherein the first chamber 111a is directly connected to the water inlet pipe 600, and the water in the water inlet pipe 600 has a high pressure after being pressurized by the water pump, and the water flow can enter the second chamber 111b through the connecting hole 412b, so the water pressure in the second chamber 111b also gradually increases and approaches the pressure in the first chamber 111a, and the high-pressure environment in the second chamber 111b will also make the diaphragm assembly 400 and the diaphragm assembly 400 seal with each other, so that the side of the throttling channel 310 close to the diaphragm assembly 400 is sealed by the diaphragm body 420, so that the wastewater passing through the throttling channel 310 will not overflow. In this embodiment, the number of connecting holes 412b is set to two, of course, the number of connecting holes 412b can also be set to one, and the number of connecting holes 412b can also be set to multiple, which is not specifically limited here.

[0063] In addition, a mounting column 412 is provided on one side of the diaphragm bracket 410 close to the diaphragm assembly 400, and a card slot 412a is provided on the outer periphery of the mounting column 412. The card slot 412a and the limit groove 411a together limit the diaphragm body 420, so that the fixing relationship between the diaphragm body 420 and the bracket is more firmly fixed, and a connecting hole 412b is provided in the mounting column 412.

[0064] It should be noted that when the drive assembly 200 is not energized, the valve core 210 presses against the diaphragm assembly 400 and blocks the valve port 413a. When the drive assembly 200 is energized, the valve core 210 moves away from the diaphragm assembly 400 to open the valve port 413a, causing the pressure in the second chamber 111b to drop instantly. The high-pressure environment in the second chamber 111b will instantly impact the diaphragm assembly 400, causing the diaphragm assembly 400 to deform in a direction away from the diaphragm assembly 400. It should be noted that the diaphragm bracket 410 is recessed on one side close to the valve core 210. Therefore, in the present embodiment, the valve port 413a is disposed on a boss. The boss is disposed here to better cooperate with the valve core 210. Of course, the boss may not be disposed, and only the valve port 413a is provided on the diaphragm bracket 410, wherein the valve port 413a is connected to the water passage, so that when the valve port 413a is opened, the second chamber 111b is connected to the low-pressure chamber 112, so that the pressure in the second chamber 111b gradually decreases.

[0065] The utility model also proposes a water purification device, which includes a throttle valve 10. The specific structure of the throttle valve 10 refers to the above embodiment. Since the water purification device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0066] The water purification device in the utility model can be a water purifier, a drinking purifier, a soft-purifier all-in-one machine, a purifier-heater all-in-one machine and other devices with water purification function.

[0067] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
