Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valve technology, and in particular to an anti-interference pressure regulating valve for electromagnetic valves. Background Technology

[0002] In modern industrial control systems and various automated equipment, solenoid valves are key components for controlling fluid flow, and their stability and reliability are paramount. However, in practical applications, solenoid valves are often subject to electromagnetic interference from the external environment. This interference can cause deviations in the solenoid valve's control signal, malfunctions, and consequently affect the normal operation of the entire system. For example, in strong electromagnetic environments, the control circuit of the solenoid valve may be affected by electromagnetic induction, resulting in inaccurate opening and closing times, unstable fluid flow control, and impacting the precision of production processes and product quality.

[0003] Existing anti-interference measures for solenoid valves often have limitations. For example, simple shielding structures can only reduce external electromagnetic interference to a certain extent, but they are not very adaptable to electromagnetic interference generated by the solenoid valve itself or to complex and ever-changing electromagnetic environments. On the other hand, some anti-interference methods through circuit design may increase the cost and structural complexity of the solenoid valve, and their effects in practical applications are not ideal. Therefore, we propose an anti-interference pressure regulating valve for solenoid valves to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-interference pressure regulating solenoid valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-interference pressure regulating valve for electromagnetic valves includes a pressure regulating valve body, on which a mounting base is installed. The top of the mounting base is provided with an anti-interference component for the pressure regulating valve body to resist interference. The anti-interference component includes a shielding cylinder, a shielding cover, a first groove, a first demagnetizing coil, a second groove, and a second demagnetizing coil. The shielding cylinder is installed on the mounting base, and the shielding cover is slidably fitted on the outer side of the shielding cylinder. A first groove is formed on the inner wall of the shielding cylinder, and a first demagnetizing coil is installed in the first groove. A second groove is formed on the inner wall of the shielding cover, and a second demagnetizing coil is installed in the second groove.

[0007] Preferably, an annular mounting plate is fixedly installed on the outer side of the shielding cover, and a disassembly and assembly mechanism is provided between the annular mounting plate and the mounting base.

[0008] Preferably, the disassembly and assembly mechanism includes mounting holes, fixing screws, and fixing nuts. The top of the annular mounting plate has multiple mounting holes at equal intervals in a ring shape, and the top of the mounting base has multiple fixing screws at equal intervals in a ring shape. The fixing screws pass through the corresponding mounting holes and are threaded with fixing nuts.

[0009] Preferably, the shielding cover has movable slots on both sides, and two movable seats are fixedly installed at the bottom of the shielding cover, with the movable seats slidably connected to the corresponding movable slots.

[0010] Preferably, the inner wall of the movable slot is provided with multiple fixing slots, and a driving slot is provided on one side of the movable seat. A fixing pin is slidably installed in the driving slot, and the fixing pin is adapted to the corresponding fixing slot.

[0011] Preferably, a threaded hole is provided on one inner wall of the drive groove, and a drive screw is installed in the threaded hole. One end of the drive screw is rotatably mounted on a fixed pin, and a knob is fixedly mounted on the other end of the drive screw.

[0012] Preferably, the fixing pin has a rotating groove, the inner wall of the rotating groove has an annular groove, and an annular seat is fixedly installed on the driving screw, and the annular seat is rotatably connected to the annular groove.

[0013] Preferably, a controller is installed on the top inner wall of the shield, and both demagnetizing coil one and demagnetizing coil two are electrically connected to the controller.

[0014] The beneficial effects of this utility model are:

[0015] 1. Under the action of the knob, drive screw and threaded hole, the drive screw can move the fixing pin, so that the fixing pin can be inserted into or released from the corresponding fixing groove, which can achieve the purpose of fixing and releasing the moving seat. The moving seat can move the shielding cover, which can adjust the height of the anti-interference component, so as to be suitable for different pressure regulating valve bodies.

[0016] 2. When placing the anti-interference component onto the mounting plate of the pressure regulating valve body, ensure that the fixing screw can pass through the corresponding mounting hole, and thread the fixing nut onto the fixing screw. The fixing nut can be used to fix the annular mounting plate and the anti-interference component.

[0017] 3. By setting up demagnetizing coil one and demagnetizing coil two, the circuit inductance of the controller can be isolated from the electromagnet inductance to prevent their inductance from interfering with each other. Through the shielding cylinder and shielding cover, external electromagnetic interference can be shielded, thereby achieving the purpose of enhancing the anti-interference performance of the solenoid valve.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an anti-interference pressure regulating valve for electromagnetic valves.

[0026] Reference Figure 1-5 An anti-interference pressure regulating valve for electromagnetic valves includes a pressure regulating valve body 101, a mounting base 102 mounted on the pressure regulating valve body 101, and an anti-interference component 2 for anti-interference of the pressure regulating valve body 101 on the top of the mounting base 102. The anti-interference component 2 includes a shielding cylinder 201, a shielding cover 202, a first groove 203, a first demagnetizing coil 204, a second groove 205, and a second demagnetizing coil 206. The shielding cylinder 201 is mounted on the mounting base 102, and the shielding cover 202 is slidably sleeved on the outer side of the shielding cylinder 201. A first groove 203 is opened on the inner wall of the shielding cylinder 201, and a first demagnetizing coil 204 is installed in the first groove 203. A second groove 205 is opened on the inner wall of the shielding cover 202, and a second demagnetizing coil 206 is installed in the second groove 205.

[0027] In this embodiment, an annular mounting plate 301 is fixedly installed on the outer side of the shielding cover 202. A disassembly and assembly mechanism is provided between the annular mounting plate 301 and the mounting base 102. The disassembly and assembly mechanism includes mounting holes 302, fixing screws 303, and fixing nuts 304. The top of the annular mounting plate 301 has multiple mounting holes 302 at equal intervals in an annular pattern. The top of the mounting base 102 has multiple fixing screws 303 at equal intervals in an annular pattern. The fixing screws 303 pass through the corresponding mounting holes 302 and are threaded with fixing nuts 304. This structural design makes the installation and disassembly of the anti-interference component 2 simple and quick. During equipment maintenance or upgrades, the anti-interference component 2 can be quickly separated from the pressure regulating valve body 101, greatly improving maintenance efficiency and reducing maintenance costs.

[0028] In this embodiment, both sides of the shielding cover 202 are provided with movable slots 401, and two movable seats 402 are fixedly installed at the bottom of the shielding cover 202, and the movable seats 402 are slidably connected to the corresponding movable slots 401. This sliding connection method provides a stable guide for the movement of the shielding cover 202, ensuring that the shielding cover 202 will not shift or shake during the height adjustment process, thereby ensuring the adjustment accuracy and stability of the anti-interference component 2.

[0029] In this embodiment, multiple fixing slots 501 are provided on the inner wall of the movable slot 401, and a driving slot 502 is provided on one side of the movable seat 402. A fixing pin 503 is slidably installed in the driving slot 502, and the fixing pin 503 is adapted to the corresponding fixing slot 501. Through the cooperation of the fixing pin 503 and the fixing slot 501, the shielding cover 202 can be firmly locked after being adjusted to a suitable height, preventing the position of the shielding cover 202 from changing due to vibration and other factors during the operation of the solenoid valve, and ensuring the continuity of the anti-interference effect.

[0030] In this embodiment, a threaded hole 601 is provided on one inner wall of the drive groove 502. A drive screw 602 is threaded into the threaded hole 601. One end of the drive screw 602 is rotatably mounted on a fixing pin 503, and a knob 603 is fixedly mounted on the other end of the drive screw 602. A rotating groove is provided on the fixing pin 503, and an annular groove is provided on the inner wall of the rotating groove. An annular seat is fixedly mounted on the drive screw 602, and the annular seat is rotatably connected to the annular groove. This structure converts the rotation of the drive screw 602 driven by the knob 603 into the linear movement of the fixing pin 503, which is labor-saving and precise in control. At the same time, the rotating connection design avoids the rotation of the fixing pin 503 when the screw rotates, ensuring the smooth insertion and removal of the fixing pin 503 and the fixing groove 501.

[0031] In this embodiment, a controller 207 is installed on the top inner wall of the shield 202, and both the first demagnetizing coil 204 and the second demagnetizing coil 206 are electrically connected to the controller 207. The controller 207 can intelligently adjust the working state of the first demagnetizing coil 204 and the second demagnetizing coil 206 according to the actual electromagnetic interference situation, realizing dynamic and precise anti-interference function, and further improving the adaptability and reliability of the solenoid valve in complex electromagnetic environments.

[0032] The working principle of this utility model is as follows: By rotating the knob 603 and the drive screw 602, under the action of the threaded hole 601, the drive screw 602 can rotate and move simultaneously. The drive screw 602 can move the fixing pin 503, allowing the fixing pin 503 to insert into or disengage from the corresponding fixing groove 501. This achieves the purpose of fixing and releasing the movable seat 402. The movable seat 402 can move the shielding cover 202, allowing the height of the anti-interference component 2 to be adjusted, thereby adapting to different pressure regulating valve bodies 101. The anti-interference component 2 is placed in a stable position. When installing the valve body 101, the fixing screw 303 can pass through the corresponding mounting hole 302, and the fixing nut 304 is threaded onto the fixing screw 303. The fixing nut 304 can be used to fix the annular mounting plate 301 and the anti-interference component 2. The demagnetizing coil 1 204 and demagnetizing coil 206 can isolate the circuit inductance of the controller 207 from the electromagnet inductance, preventing their inductance from interfering with each other. The shielding cylinder 201 and the shielding cover 202 can shield external electromagnetic interference, thereby achieving the purpose of strengthening the anti-interference performance of the solenoid valve.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
