[0002] In the current fluid pipeline system, the pressure reducing valve is widely used as a key pressure regulating device. With the improvement of the industrial automation level, the traditional mechanical pressure reducing valve can no longer meet the requirements of high-precision and real-time regulation. At the same time, in order to increase the service life of the pressure reducing valve and prevent scale accumulation in the pressure reducing valve, usually, before the water flow enters the pressure reducing valve, it needs to be filtered through a filter to remove impurities in the water before the liquid enters the pressure reducing valve.

[0003] In some of the current mainstream solutions, some pressure reducing valves have achieved automatic control, and some have set up a filtering device on the valve body to filter the liquid.

[0030] The following further elaborates on this application Figures 1-5 in conjunction with the attached drawings.

[0031] An embodiment of this application discloses an intelligent pressure reducing valve. Refer to Figure 1 and Figure 2 , which includes a valve body mechanism 1, a transmission mechanism 2, a control mechanism 3, and a cleaning mechanism 4. Among them, 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. A support housing is arranged on the valve body mechanism 1 to protect other components. Such a structural arrangement realizes the effective regulation of fluid pressure and improves the working efficiency and stability of the pressure reducing valve.

[0032] During specific operation, when liquid enters the valve body mechanism 1, the control mechanism 3 controls the transmission mechanism 2 to adjust, reduce the pressure of the water flow, and the cleaning assembly cleans a part of the valve body assembly to complete the pressure reduction work of the water flow.

[0033] Refer to Figure 1 and Figure 2, the 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. Flange plates for connection are correspondingly provided on the water inlet 102 and the water outlet 103. The support assembly 101 includes a pressure reduction chamber 1011. The shape of the pressure reduction chamber 1011 can be ellipsoidal or cuboid, which varies according to the actual situation. A partition plate 1012 is provided on the pressure reduction chamber 1011. The partition plate 1012 divides the pressure reduction 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 far from the transmission mechanism 2 is the second chamber 1014. The water inlet 102 communicates with the first chamber 1013. The filter assembly 105 is arranged in the first chamber 1013. The water outlet 103 communicates with the second chamber 1014. The pressure reduction chamber 1011 is generally made of metal material, having good strength and corrosion resistance, and can withstand a certain pressure. The partition plate 1012 can be welded inside the pressure reduction chamber 1011 to play a role in stable separation.

[0034] The working process of the valve body mechanism 1: The fluid enters the first chamber 1013 from the water inlet 102. After being filtered by the filter assembly 105, the flow rate and pressure are adjusted through the valve core assembly 104, then enter the second chamber 1014, and finally flow out from the water outlet 103. The setting of the partition plate 1012 enables the fluid to flow orderly in the pressure reduction chamber 1011, facilitating pressure adjustment and filtering operations.

[0035] Reference Figure 1 , Figure 2 and Figure 3 , the valve core assembly 104 includes a valve seat 1041 arranged on the partition plate 1012.

A guide rod 1044 is provided on the side of the conical block 1043 pointing to the transmission mechanism 2. The guide rod 1044 passes through the pressure reduction chamber 1011. A guide magnetic plate 1045 is provided on the side of the guide rod 1044 far from the conical block 1043. The valve seat 1041 is usually fixed on the partition plate 1012 by bolts to ensure the stability of the connection. The cooperation of the conical hole 1042 and the conical block 1043 can ensure good sealing performance. The guide rod 1044 can be a metal rod, which plays a role in guiding the movement of the conical block 1043. The guide magnetic plate 1045 is generally made of permanent magnetic material for subsequent cooperation with the electromagnet sheet 2056. As a preferred embodiment, the guide rod 1044 is a cross-shaped rod.

[0036] Working process of the valve core assembly 104: When the guiding magnetic plate 1045 is subjected to magnetic force, it drives the guiding rod 1044 and the conical block 1043 to move within the conical hole 1042, changing the opening degree between the conical block 1043 and the valve seat 1041, thereby realizing the regulation of fluid flow rate and pressure. At the same time, the pressure change during the pressure reduction process enables the conical block 1043 to perform a small reciprocating motion in the vertical direction, and then drives the guiding magnetic plate 1045 to reciprocate to provide cleaning power for the cleaning mechanism.

[0037] Reference 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. It also includes a support frame 203 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. An stepper motor is adopted, which can achieve precise angle control. The first gear 202 is key-connected to the transmission shaft of the rotating motor 201 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 a ring-shaped metal structure, providing an installation basis for the moving assembly 205.

[0038] Working process of the transmission mechanism 2: After the rotating motor 201 is started, it drives the transmission shaft and the first gear 202 to rotate. The first gear 202 meshes with the second gear 2057 on the moving assembly 205, transmitting the power to the moving assembly 205, causing the moving assembly 205 to generate corresponding motion.

[0039] Reference Figure 3 、 Figure 4, the motion component 205 includes a motion sleeve 2051 helically connected to the support ring 204. A motion rod 2052 is slidably connected inside the motion sleeve 2051. The motion rod 2052 passes through the motion sleeve 2051 and points to the guiding magnetic plate 1045. A motion spring 2053 is arranged between the motion rod 2052 and the motion sleeve 2051. One end of the motion rod 2052 away from the motion sleeve 2051 is connected with a mounting block 2054. Mounting protrusions 2055 are arranged on the mounting block 2054. Electromagnetic sheets 2056 are arranged inside the mounting protrusions 2055.

It also includes a second gear 2057 coaxially arranged on the motion sleeve 2051, and 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. The motion rod 2052 slides inside the motion sleeve 2051, and the motion spring 2053 plays a role in buffering and resetting. The guiding magnetic plate 1045 can be movably connected with the mounting protrusions 2055. As an embodiment, a connection method of groove and block is adopted. The electromagnetic sheets 2056 generate magnetic force when electrified, adsorb the guiding magnetic plate 1045, and lose magnetic force when powered off. The second gear 2057 and the motion sleeve 2051 are connected by splines to ensure synchronous rotation and always mesh with the first gear 202 to achieve power transmission.

[0040] Working process of the motion component 205: The rotating motor 201 drives the first gear 202 to rotate. The first gear 202 drives the second gear 2057 and the motion sleeve 2051 to rotate. Since the motion sleeve 2051 and the support ring 204 are in helical transmission, the motion sleeve 2051 will drive the motion rod 2052 to do linear motion. When the electromagnetic sheets 2056 are electrified to generate magnetic force and adsorb the guiding magnetic plate 1045, the motion of the motion rod 2052 will drive the guiding magnetic plate 1045, the guiding rod 1044 and the conical block 1043 to move, realizing pressure adjustment.

[0041] Reference Figure 2 and 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 component 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 volume and low cost, or a programmable logic controller can be adopted, which has more powerful functions and is suitable for complex control requirements. The wireless communication module 302 can be a Bluetooth module, a WiFi module, etc., to realize remote data transmission and control. The pressure sensor 303 is generally a piezoelectric sensor, which can accurately measure the pressure of the water outlet 103 and transmit the signal to the MCU controller 301.

[0042] Working process of the control mechanism 3: 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 according to the preset pressure target value, and then controls the forward and reverse rotation and speed of the rotation motor 201 to achieve precise adjustment of the pressure reducing valve pressure. At the same time, the wireless communication module 302 can remotely transmit data such as the working state of the pressure reducing valve, facilitating operation personnel to monitor and control.

[0043] Reference Figure 5 , the filtering component 105 includes a filter plate 1051 provided on the inner wall of the support component 101.

The filter plate 105 is usually a metal plate, and the filter holes 1052 are formed on its surface through punching processing. The size and density of the filter holes 1052 are determined according to the actual filtering requirements. The mounting shaft 1053 can be a metal shaft, and is fixed to the filter plate 1051 by welding or key connection, providing installation and rotation support for the cleaning mechanism 4.

[0044] Working process of the filtering component 105: After the fluid enters the first chamber 1013, it passes through the filter holes 1052 on the filter plate 1051. The impurities are filtered and remain on the filter plate 1051, while the clean fluid continues to flow.

The toggle rods 406 can move into the feed grooves 404. A connecting component 407 is provided at one end of the cleaning shaft 405 away from the toggle rods 406. The cleaning ring 401 is generally a ring-shaped plastic or metal structure, which is light and corrosion-resistant. The cleaning plates 402 are connected to the cleaning ring 401 by bolts or welding. The cleaning bristles 403 can be nylon bristles, which are soft and wear-resistant and can effectively clean the impurities in the filter holes 1052. The shape and size of the feed grooves 404 should match the toggle rods 406 to ensure that the toggle rods 406 can smoothly enter and exit. The cleaning shaft 405 is rotatably connected to the support assembly 101 through bearings to reduce rotational friction.

[0046] Working process of the cleaning mechanism 4: When the connecting component 407 drives the cleaning shaft 405 to rotate, the toggle rods 406 on the cleaning shaft 405 will enter the feed grooves 404 on the cleaning ring 401, driving the cleaning ring 401 and the cleaning plates 402 to rotate around the mounting shaft 1053. The cleaning bristles 403 on the cleaning plates 402 will enter the filter holes 1052 with the rotation to clean the impurities in the filter holes 1052 and prevent the filter holes 1052 from being blocked.

[0047] Reference Figure 3 、 Figure 4, the connecting component 407 is connected to the connecting rod 4071 on the guiding magnetic plate 1045. One end of the connecting rod 4071 away from the guiding magnetic plate 1045 is connected with a sliding block 4072. The sliding block 4072 is arranged on the sliding frame 4073. The sliding frame 4073 is connected to the pressure reducing chamber 1011. The sliding block 4072 can move in the vertical direction. A first hook 4074 and a second hook 4075 are hinged on the sliding block 4072. A connecting spring 4076 is arranged between the first hook 4074 and the second hook 4075. A ratchet component 408 is further included and arranged between the first hook 4074 and the second hook 4075. The connecting rod 4071 and the guiding magnetic plate 1045 are connected by welding or bolts to transmit motion. The first hook 4074 and the second hook 4075 are hinged on the sliding block 4072 through a pin shaft. The connecting spring 4076 functions to reset them. The ratchet component 408 includes a ratchet seat 4081 arranged on the pressure reducing chamber 1011. A connecting shaft 4082 is rotatably connected to the ratchet seat 4081. One end of the connecting shaft 4082 is connected with a ratchet 4083. The other end of the connecting shaft 4082 is connected with a first bevel gear 4084.

The ratchet seat 4081 is fixed on the pressure reducing chamber 1011 by bolts. The connecting shaft 4082 is rotatably connected to the ratchet seat 4081 through a bearing. The ratchet 4083 and the first bevel gear 4084 are connected to the connecting shaft 4082 by a key to ensure synchronous rotation. The meshing of the first bevel gear 4084 and the second bevel gear 4085 realizes the vertical transmission of power, drives the mounting shaft 1053 to rotate, and thus enables the cleaning mechanism 4 to clean the filter component 105.

[0048] Working process of the connecting component 407: When the guiding magnetic plate 1045 moves, it will drive the connecting rod 4071 and the sliding block 4072 to move in the vertical direction on the sliding frame 4073. At the same time, when the water flow pressure changes, it will also drive the sliding block 4072 to move back and forth in the vertical direction. The first hook 4074 and the second hook 4075 cooperate with the ratchet component 408 during the movement of the sliding block 4072, 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 for cleaning operations.

[0049] The implementation principle of an intelligent pressure reducing valve in an embodiment of this application is as follows: When the rotating motor 201 is started, through the meshing of the first gear 202 and the second gear 2057, the moving sleeve 2051 is driven to rotate. Since the moving sleeve 2051 is in screw drive with 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 adsorbs the guiding magnetic plate 1045, the guiding rod 1044 and the conical block 1043 will move together with the moving rod 2052 to realize the adjustment of the opening degree 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 the rotation speed of the rotating motor 201 according to the preset pressure target value to realize precise pressure adjustment. At the same time, when the guiding magnetic plate 1045 moves, the slider 4072 is driven to move on the sliding frame 4073 through the connecting rod 4071. The first claw 4074 and the second claw 4075 on the slider 4072 cooperate with the ratchet assembly 408 to make the connecting shaft 4082 rotate. When not adjusted, the ratchet assembly 408 will also be driven to rotate due to the water flow fluctuation, and then the installation shaft 1053 is 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 filtering assembly 105 to avoid blockage of the filtering assembly 105 and ensure the normal flow of the fluid. This intelligent pressure reducing valve has a reasonable structure, realizes precise pressure adjustment and automatic cleaning of the filtering assembly 105, improves work efficiency and stability, overcomes many defects of traditional pressure reducing valves, and meets the requirements of modern industry for high-precision and automated equipment.

[0050] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
