DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The present application discloses an intelligent pressure reducing valve. Figure 1 、 Figure 2 , including a valve body mechanism 1, a transmission mechanism 2, a control mechanism 3 and a cleaning mechanism 4, wherein the transmission mechanism 2 is arranged on the valve body mechanism 1, the control mechanism 3 is used to control the movement of the transmission mechanism 2, the cleaning mechanism 4 is arranged on the filter assembly 105, and is driven by the support assembly 101 to clean the filter assembly 105, and a supporting shell is provided on the valve body mechanism 1 to protect other components. Such a structural arrangement realizes the effective regulation of the fluid pressure and improves the working efficiency and stability of the pressure reducing valve.

[0039] During specific operation, liquid enters the valve body mechanism 1 and is adjusted through the control mechanism 3 to control the transmission mechanism 2 to reduce the pressure of the water flow. A part of the valve body assembly is cleaned through the cleaning assembly to complete the pressure reduction of the water flow.

[0040] refer to Figure 1 、 Figure 2The valve body mechanism 1 includes a water inlet 102, a water outlet 103, a support assembly 101, a filter assembly 105, and a valve core assembly 104. The water inlet 102 and the water outlet 103 are respectively provided with flanges for connection. The support assembly 101 includes a decompression chamber 1011. The shape of the decompression chamber 1011 can be ellipsoidal or rectangular, depending on the actual situation. The decompression chamber 1011 is provided with a partition plate 1012, which divides the decompression chamber 1011 into a first chamber 1013 and a second chamber 1014. The side of the partition plate 1012 close to the transmission mechanism 2 is the first chamber 1013, and the side of the partition plate 1012 away from the transmission mechanism 2 is the second chamber 1014. The water inlet 102 is connected to the first chamber 1013, the filter assembly 105 is arranged in the first chamber 1013, and the water outlet 103 is connected to the second chamber 1014. The decompression chamber 1011 is generally made of metal, which has good strength and corrosion resistance and can withstand a certain pressure. The partition plate 1012 can be welded in the decompression chamber 1011 to play a role in stabilizing the partition.

[0041] Valve mechanism 1 operates as follows: Fluid enters first chamber 1013 from water inlet 102, is filtered by filter assembly 105, passes through valve core assembly 104 for flow and pressure adjustment, then enters second chamber 1014 and exits through outlet 103. The provision of partition plate 1012 ensures orderly fluid flow within decompression chamber 1011, facilitating pressure regulation and filtering operations.

[0042] refer to Figure 1 、 Figure 2 as well as Figure 3 The valve core assembly 104 includes a valve seat 1041 mounted on the partition plate 1012. The valve seat 1041 is provided with a tapered hole 1042 and a tapered block 1043 movably connected to the tapered hole 1042. A guide rod 1044 is provided on the side of the tapered block 1043 facing the transmission mechanism 2. The guide rod 1044 passes through the pressure relief chamber 1011. A guide magnetic plate 1045 is provided on the side of the guide rod 1044 facing away from the tapered block 1043. The valve seat 1041 is typically secured to the partition plate 1012 with bolts to ensure a secure connection. The tapered hole 1042 and tapered block 1043 ensure a good seal. The guide rod 1044 can be a metal rod and serves to guide the movement of the tapered block 1043. The guide magnetic plate 1045 is typically made of a permanent magnetic material to facilitate subsequent interaction with the electromagnet 2056. In a preferred embodiment, the guide rod 1044 is a cross-shaped rod.

[0043] Working process of the valve core assembly 104: When the guide magnetic plate 1045 is subjected to magnetic force, it will drive the guide rod 1044 and the conical block 1043 to move in the conical hole 1042, changing the opening between the conical block 1043 and the valve seat 1041, thereby realizing the regulation of fluid flow and pressure. At the same time, the pressure change during the decompression process can make the guide conical block 1043 perform a small reciprocating motion in the vertical direction, thereby driving the guide magnetic plate 1045 to reciprocate and provide cleaning power to the cleaning mechanism.

[0044] refer to Figure 3 、 Figure 4 The transmission mechanism 2 includes a rotating motor 201 arranged on the outer wall of the support assembly 101, a first gear 202 is arranged on the transmission shaft of the rotating motor 201, and a support frame 203 is arranged on the outer wall of the support assembly 101, a support ring 204 is arranged on the support frame 203, and a moving assembly 205 is arranged on the support ring 204. The rotating motor 201 is the power source of the transmission mechanism 2, and adopts a stepping motor to achieve precise angle control. The first gear 202 is connected to the transmission shaft of the rotating motor 201 by a key to ensure synchronous rotation. The support frame 203 is generally a metal bracket, which is connected to the outer wall of the support assembly 101 by welding or bolts to provide stable support for the support ring 204. The support ring 204 is an annular metal structure that provides an installation base for the moving assembly 205.

[0045] Working process of transmission mechanism 2: After the rotating motor 201 is started, it drives the transmission shaft and the first gear 202 to rotate, and the first gear 202 engages with the second gear 2057 on the motion component 205, transmitting power to the motion component 205, causing the motion component 205 to generate corresponding movement.

[0046] refer to Figure 3 、 Figure 4The motion assembly 205 includes a motion sleeve 2051 helically connected to the support ring 204. A motion rod 2052 is slidably connected within the motion sleeve 2051. The motion rod 2052 extends through the motion sleeve 2051 and points toward the guide magnetic plate 1045. A motion spring 2053 is disposed between the motion rod 2052 and the motion sleeve 2051. The end of the motion rod 2052 away from the motion sleeve 2051 is connected to a mounting block 2054. The mounting block 2054 is provided with a mounting protrusion 2055. An electromagnet 2056 is disposed within the mounting protrusion 2055. The guide magnetic plate 1045 can move into the mounting protrusion 2055. The motion assembly 2055 also includes a second gear 2057 coaxially disposed on the motion sleeve 2051. The second gear 2057 can always mesh with the first gear 202. The helical transmission structure of the motion sleeve 2051 and the support ring 204 can convert rotational motion into linear motion. Motion rod 2052 slides within motion sleeve 2051, with motion spring 2053 providing both a buffer and a reset function. Guide magnetic plate 1045 is movably connected to mounting protrusion 2055, employing a slot-and-block connection. Electromagnetic plate 2056 generates a magnetic force when powered, attracting guide magnetic plate 1045. The magnetic force is lost when powered off. Second gear 2057 is splined to motion sleeve 2051, ensuring synchronous rotation and always meshing with first gear 202 to achieve power transmission.

[0047] The operating process of motion assembly 205 is as follows: the rotating motor 201 drives the first gear 202, which in turn drives the second gear 2057 and the motion sleeve 2051. Due to the helical transmission between the motion sleeve 2051 and the support ring 204, the motion sleeve 2051 drives the motion rod 2052 in linear motion. When the electromagnet 2056 is energized to generate magnetic force to attract the guide magnetic plate 1045, the movement of the motion rod 2052 drives the guide magnetic plate 1045, the guide rod 1044, and the tapered block 1043, achieving pressure regulation.

[0048] refer to Figure 2 as well as Figure 4 The control mechanism 3 includes an MCU controller 301 and a wireless communication module 302 arranged on the outer wall of the support assembly 101, and also includes a pressure sensor 303 arranged on the inner wall of the water outlet 103. The MCU controller 301 is the control core of the entire intelligent pressure reducing valve. It can be a single-chip microcomputer, which has the advantages of small size and low cost, or a programmable logic controller, which has more powerful functions and is suitable for complex control requirements. The wireless communication module 302 can be a Bluetooth module, WiFi module, etc., to realize remote data transmission and control. The pressure sensor 303 is generally a piezoelectric sensor that can accurately measure the pressure of the water outlet 103 and transmit the signal to the MCU controller 301.

[0049] Control mechanism 3 operates as follows: The pressure sensor 303 monitors the pressure at the water outlet 103 in real time and transmits the pressure signal to the MCU controller 301. The MCU controller 301 analyzes and processes the received pressure signal based on the preset pressure target value, then controls the forward and reverse rotation and speed of the rotary motor 201 to precisely regulate the pressure of the pressure reducing valve. Furthermore, the wireless communication module 302 remotely transmits data such as the operating status of the pressure reducing valve, facilitating operator monitoring and control.

[0050] refer to Figure 5 The filter assembly 105 includes a filter plate 1051 mounted on the inner wall of the support assembly 101.

The shape and size of the feed slot 404 must match the toggle rod 406 to ensure smooth entry and exit. The cleaning shaft 405 is rotatably connected to the support assembly 101 via a bearing to reduce rotational friction.

[0053] Cleaning mechanism 4 operates as follows: When connecting assembly 407 rotates cleaning shaft 405, toggle rod 406 on cleaning shaft 405 enters feed slot 404 on cleaning ring 401, driving cleaning ring 401 and cleaning plate 402 to rotate about mounting axis 1053. Cleaning bristles 403 on cleaning plate 402 enter filter holes 1052 as they rotate, cleaning impurities within filter holes 1052 and preventing clogging.

The meshing of the first bevel gear 4084 and the second bevel gear 4085 enables vertical power transmission, driving the mounting shaft 1053 to rotate, thereby allowing the cleaning mechanism 4 to clean the filter assembly 105.

[0055] Connecting assembly 407 operates as follows: When the guide magnetic plate 1045 moves, it drives the connecting rod 4071 and the sliding block 4072 to move vertically on the sliding frame 4073. Simultaneously, changes in water pressure also drive the sliding block 4072 to move back and forth vertically. During the movement of the sliding block 4072, the first hook 4074 and the second hook 4075 engage with the ratchet assembly 408, causing the connecting shaft 4082 to rotate unidirectionally. The rotation of the connecting shaft 4082 is transmitted to the mounting shaft 1053 through the meshing of the first bevel gear 4084 and the second bevel gear 4085, driving the cleaning mechanism 4 to rotate and perform the cleaning operation.

[0056] The implementation principle of an intelligent pressure reducing valve in an embodiment of the present application is as follows: the rotating motor 201 is started, and the first gear 202 and the second gear 2057 are engaged, driving the moving sleeve 2051 to rotate. Due to the spiral transmission between the moving sleeve 2051 and the support ring 204, the moving sleeve 2051 will drive the moving rod 2052 to move linearly. When the electromagnet sheet 2056 is energized to generate magnetic force and attract the guide magnetic plate 1045, the guide rod 1044 and the conical block 1043 will move together with the moving rod 2052 to adjust the opening between the conical block 1043 and the valve seat 1041, thereby controlling the flow rate and pressure of the fluid. The pressure sensor 303 monitors the pressure of the water outlet 103 in real time and transmits the signal to the MCU controller 301. The MCU controller 301 controls the forward and reverse rotation and speed of the rotating motor 201 according to the preset pressure target value to achieve precise pressure regulation. At the same time, when the guide magnetic plate 1045 moves, the connecting rod 4071 drives the sliding block 4072 to move on the sliding frame 4073. The first hook 4074 and the second hook 4075 on the sliding block 4072 cooperate with the ratchet assembly 408 to rotate the connecting shaft 4082. In the absence of adjustment, the ratchet assembly 408 will also be driven to rotate due to water flow fluctuations, and then the installation shaft 1053 will be driven to rotate through the first bevel gear 4084 and the second bevel gear 4085. The cleaning mechanism 4 on the installation shaft 1053 automatically cleans the filter assembly 105, preventing the filter assembly 105 from being blocked and ensuring the normal flow of fluid. This intelligent pressure reducing valve has a reasonable structure, realizes precise pressure regulation and automatic cleaning of the filter assembly 105, improves work efficiency and stability, overcomes many defects of traditional pressure reducing valves, and meets the needs of modern industry for high-precision and automated equipment.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
