Description

Technical Field

[0001] This utility model relates to the field of valve body technology, specifically a self-cleaning valve body structure. Background Technology

[0002] A valve body, also known as the valve frame, is a component used to control the flow of media in a pipeline. Valve bodies are typically made of metal, and their shape and structure vary depending on the application.

[0003] Traditional solenoid valves rely on filtration or backflushing to prevent clogging, but hard scale or sticky dirt can still easily clog the valve cavity, requiring frequent disassembly and cleaning, resulting in unsatisfactory performance. Utility Model Content

[0004] This invention provides a self-cleaning valve body structure to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning valve body structure, including a valve body, wherein a solenoid valve assembly is provided on the top of the valve body for preventing internal blockage of the valve body by vibration, and a sensing component located on one side of the solenoid valve assembly is provided inside the valve body for sensing water flow.

[0006] Furthermore, the solenoid valve assembly is a vibration-type solenoid valve.

[0007] Furthermore, the solenoid valve assembly includes a solenoid valve coil assembly, a solenoid valve coil base plate, and a solenoid valve diaphragm.

[0008] Furthermore, each side of the top of the solenoid valve coil base plate is provided with at least one buckle, and the solenoid valve coil base plate is snapped to the bottom of the solenoid valve coil assembly by the buckles.

[0009] Furthermore, a solenoid valve diaphragm is provided at the bottom of the solenoid valve coil base plate, and the bottom of the solenoid valve diaphragm extends into the interior of the valve body.

[0010] Furthermore, a valve seat is provided on the top of the valve body, and the solenoid valve assembly is fixed to the top of the valve seat by a screw.

[0011] Furthermore, the sensing component includes a front shell of the flow guide tube, a rear shell of the flow guide tube, and a Hall effect sensing circuit board.

[0012] Furthermore, the rear shell of the guide tube is sleeved on one end of the front shell of the guide tube, and an induction rotor with one end extending into the interior of the rear shell of the guide tube is movably disposed inside the front shell of the guide tube.

[0015] Compared with the prior art, the present invention provides a self-cleaning valve body structure, which has the following beneficial effects:

[0016] This self-cleaning valve body structure monitors the water flow status in real time through a sensing component. When it detects that there is no water flow after the valve is opened, it immediately triggers the vibration cleaning function of the solenoid valve component. The vibration-type solenoid valve generates vibration to directly destroy the scale or impurity deposits in the valve cavity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model discloses a self-cleaning valve body structure, including a valve body 1. The top of the valve body 1 is provided with a solenoid valve assembly 11 for preventing internal blockage of the valve body 1 by vibration. The inside of the valve body 1 is provided with a sensing component 12 located on one side of the solenoid valve assembly 11 for sensing water flow. One end of the valve body 1 is also provided with a connector 15 for connecting to a pipe.

[0026] Specifically, the solenoid valve assembly 11 is a vibration type solenoid valve. The solenoid valve assembly 11 includes a solenoid valve coil assembly 111, a solenoid valve coil base plate 112, and a solenoid valve diaphragm 113. The top of both sides of the solenoid valve coil base plate 112 is provided with at least one buckle 114. The solenoid valve coil base plate 112 is snapped to the bottom of the solenoid valve coil assembly 111 by the buckles 114. The bottom of the solenoid valve coil base plate 112 is provided with a solenoid valve diaphragm 113, and the bottom of the solenoid valve diaphragm 113 extends into the interior of the valve body 1.

[0027] In this embodiment, the solenoid valve assembly 11 and the sensing assembly 12 cooperate with each other under the control of a controller. The solenoid valve assembly 11 also includes a pulse drive module, an elastic resonant arm, and an inertial counterweight. The pulse drive module is used to generate a pulse current to drive the coil assembly. The elastic resonant arm connects the coil base plate and the diaphragm, converting electromagnetic energy into mechanical vibration waves. The inertial counterweight is fixed below the diaphragm and amplifies the micro-vibration of the resonant arm through the inertial effect. When the sensing assembly 12 senses water flow, it sends a signal to the controller, which then activates the solenoid valve assembly 11 to open the valve. If the sensing assembly 12 does not sense water flow after the valve is opened, it is considered that the valve opening has failed, which may indicate a blockage. In this case, the vibration cleaning function needs to be activated to dissipate the dirt at the valve and open the valve, reducing the maintenance of the valve body 1, increasing its service life, and achieving economic benefits.

[0028] Specifically, a valve seat 13 is provided on the top of the valve body 1, and the solenoid valve assembly 11 is fixed to the top of the valve seat 13 by a screw 115.

[0029] In this embodiment, the screw 115 provides rigid support to prevent vibration from causing the solenoid valve assembly 11 to shift, thus ensuring the alignment accuracy between the valve core and the valve cavity.

[0030] Specifically, the sensing component 12 includes a front shell 121 of the flow guide tube, a rear shell 122 of the flow guide tube, and a Hall sensor circuit board 124. The rear shell 122 of the flow guide tube is sleeved on one end of the front shell 121 of the flow guide tube, and an induction rotor 125 is movably disposed inside the front shell 121 of the flow guide tube, with one end extending into the interior of the rear shell 122 of the flow guide tube.

[0031] In this embodiment, the induction rotor 125 is matched with the Hall sensor circuit board 124. The induction rotor 125 has an external engineering plastic and an internal neodymium iron boron magnet structure, which has good corrosion resistance. The induction rotor 125 rotates with the water flow. The Hall sensor circuit board 124 detects the water flow through magnetic signals. The Hall element captures the speed change and provides real-time feedback on the flow fluctuation. When the sensing component 12 detects the water flow, it activates the solenoid valve component 11 to open the valve.

[0032] Specifically, a retaining ring 123 is provided at the end of the front shell 121 of the guide tube away from the rear shell 122 of the guide tube.

[0033] In this embodiment, the fixed retaining ring 123 constrains the displacement of the front shell 121 of the guide tube, so as to prevent the sensing component 12 from detaching from the valve body 1 due to water flow impact.

[0034] Specifically, the bottom of the valve body 1 is provided with a mounting base 14 located directly below the induction rotor 125, and the Hall sensor circuit board 124 is embedded inside the mounting base 14.

[0035] In this embodiment, the mounting base 14 isolates the Hall circuit board from the water flow, extending the life of electronic components.

[0036] In summary, this self-cleaning valve body structure monitors the water flow status in real time through the sensing component 12. When it detects that there is no water flow after the valve is opened, it immediately triggers the vibration cleaning function of the solenoid valve component 11. The vibration-type solenoid valve generates vibration to directly destroy the scale or impurity deposits in the valve cavity, restoring the valve opening and closing function without manual intervention. The blockage rate is greatly reduced, realizing "sensing to execution" closed-loop control, avoiding ineffective vibration energy consumption, extending component life, and featuring a simple and compact structure that is economical and has broad application prospects.
