Description

Technical Field

[0001] This utility model relates to the technical field of solenoid valve inlet devices, specifically a solenoid valve inlet device with a filtering function. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, but not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common types are check valves, safety valves, directional control valves, and speed control valves.

[0003] However, when existing solenoid valves are in use, the fluid passing through the solenoid valve sometimes contains impurities. These impurities can easily cause blockages inside the solenoid valve as the fluid passes through, affecting its normal operation. Therefore, this does not meet the current requirements. To address this, we propose a solenoid valve inlet device with a filtering function. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 One embodiment of this utility model is a solenoid valve inlet device with a filtering function, including a connecting threaded head 1.

[0023] The filter barrel 2 is fixedly installed on the upper end of the connecting threaded head 1. The upper end of the filter barrel 2 is rotatably installed with a connecting part 5. The lower end of the connecting part 5 is installed with an upper filter screen 8. The upper filter screen 8 is fixedly connected to the connecting part 5. The lower end of the upper filter screen 8 is installed with a conical filter plate 9. Installing the conical filter plate 9 and the upper filter screen 8 can filter the fluid entering the solenoid valve 7, remove impurities in the fluid, prevent impurities from clogging the solenoid valve 7, and ensure the normal use of the solenoid valve 7. The conical filter plate 9 is rotatably connected to the upper filter screen 8 and fixedly connected to the filter barrel 2.

[0024] The scraper plate 10 is fixedly installed inside the lower end of the upper filter screen 8. The cleaning plate 11 is installed on the lower end of the outer side of the upper filter screen 8. The cleaning plate 11 is fixedly connected to the upper filter screen 8. The installation of the cleaning plate 11 and the scraper plate 10 allows the rotating connecting part 5 to filter the impurities at the upper end of the conical filter plate 9 when the rotating part 5 rotates. This facilitates the discharge of impurities through the waste discharge pipe 3 and prevents impurities from accumulating together. The lower ends of the cleaning plate 11 and the scraper plate 10 are in contact with the upper end of the conical filter plate 9. Flow grooves 12 are provided at the lower ends of both sides of the upper filter screen 8.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A waste discharge pipe 3 is installed on one side of the filter barrel 2. The waste discharge pipe 3 is welded to the filter barrel 2. A sealing plug 4 is installed at one end of the filter barrel 2. Installing the sealing plug 4 makes it easy for the staff to clean out the impurities filtered by the device regularly, reducing the difficulty of using the device and enhancing its convenience. The sealing plug 4 is connected to the filter barrel 2 by threads. A pipe connector 6 is installed at the upper end of the connecting part 5. The pipe connector 6 is fixedly connected to the connecting part 5. A solenoid valve 7 is installed at the lower end of the connecting threaded head 1. The solenoid valve 7 is connected to the connecting threaded head 1 by threads. A connecting wire 13 is installed at the upper end of one side of the solenoid valve 7. The connecting wire 13 is electrically connected to the solenoid valve 7.

[0026] Working principle: During use, the operator installs the fitting on the upper end of the pipe connector 6. Since the connector 5 and the filter barrel 2 are rotatably connected, the operator periodically moves the fitting to generate a certain torsional force, which in turn causes the connector 5 to rotate at a certain angle. This causes the connector 5 to rotate the upper filter screen 8, thereby automatically cleaning the conical filter plate 9 with the scraper plate 10 and cleaning plate 11 inside the upper filter screen 8, preventing the accumulation of debris and blockage in the conical filter plate 9. After the device has been used for a long time, the operator rotates the connector 5 to make a large rotation, allowing the scraper plate 10 and cleaning plate 11 to thoroughly clean the conical filter plate 9. Then, the operator unscrews the sealing plug 4. The device allows impurities to be discharged through the waste discharge pipe 3, effectively preventing the solenoid valve 7 from clogging. The conical filter plate 9 and upper filter screen 8 are installed to filter the fluid entering the solenoid valve 7, removing impurities from the fluid and preventing them from clogging the solenoid valve 7, thus ensuring the normal operation of the solenoid valve 7. The cleaning plate 11 and scraper 10 are installed so that when the rotating connection part 5 rotates, the cleaning plate 11 and scraper 10 can filter the impurities at the upper end of the conical filter plate 9, making it easier for impurities to be discharged through the waste discharge pipe 3 and preventing impurities from accumulating together. The sealing plug 4 is installed so that the staff can clean the impurities filtered by the device regularly, reducing the difficulty of using the device and enhancing its convenience.
