Abstract
Description
Technical Field
[0001] This utility model relates to the field of solenoid valve technology, and more specifically, to an anti-clogging solenoid valve. Background Technology
[0002] Solenoid valves are automated actuators that use electromagnetic force to control the on / off state or flow direction of fluids. They are basic equipment in industrial control systems and can be installed in the exhaust pipes of natural gas trucks to control exhaust emissions.
[0003] Because natural gas exhaust from automobiles contains a certain amount of carbon deposits, these deposits can easily adhere to the valve core when they enter the exhaust gas control valve, causing the valve to not close properly later. To avoid this, a filter is usually installed at the intake end of the exhaust gas control valve to intercept the carbon deposits in the exhaust gas. However, carbon deposits can also easily adhere to the filter and cause blockages, so the filter needs to be frequently removed from the valve for cleaning, which is inconvenient. Utility Model Content
[0004] This invention provides an anti-clogging solenoid valve, which solves the technical problem of poor fixation effect on the patient's head in the prior art.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] An anti-clogging solenoid valve includes a valve body with an inlet pipe and an outlet pipe connected to its two sides respectively. A sleeve is fixedly connected to the end of the inlet pipe, and a cap is provided at the top of the sleeve. An inlet pipe is provided at the top of the cap. The solenoid valve structure also includes a set of filter screen sleeves with an annular end on the top edge of the filter screen sleeves. A retaining ring is provided on the inner side of the port of the sleeve. A pressure block is provided on the inner wall of the cap. A first rotating shaft is rotatably connected inside the cap. A brush plate is connected to the bottom surface of the first rotating shaft. A power component for driving the first rotating shaft to rotate is also provided on the cap.
[0007] Furthermore, the power assembly includes a motor mounted on the side wall of the cover, a second rotating shaft connected to one end of the motor output shaft and extending into the cover, and a bevel gear set disposed between the ends of the second rotating shaft and the first rotating shaft and meshing with each other.
[0008] Furthermore, a sealing gasket is provided on the bottom surface of the annular end.
[0009] Furthermore, a positioning pin is provided at the bottom of the annular end, and a positioning hole corresponding to the positioning pin is provided on the surface of the retaining ring.
[0010] Furthermore, a threaded joint is provided between the cap and the sleeve to cooperate with each other, and an anti-slip handle is fixedly provided on the outer surface of the cap.
[0011] Furthermore, the brush plates are connected in three groups at equal intervals on the surface of the first rotating shaft, and each group of brush plates is fixedly connected to the first rotating shaft by two fixing rods.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the combined action of the sleeve, the cap, the annular end, the retaining ring, and the pressure block, the filter screen sleeve can be fixed inside the sleeve, so that the filter screen sleeve can filter the exhaust gas passing through the sleeve and intercept the carbon deposits in the exhaust gas in the filter screen sleeve. The power component can drive the first rotating shaft to rotate, which will drive the brush plate to rotate against the inner wall of the filter screen sleeve. During this process, the brush plate can sweep off the carbon deposits attached to the inner wall of the filter screen sleeve, thereby effectively preventing the attached carbon deposits from clogging the filter screen sleeve, effectively reducing the frequency of removing the filter screen sleeve for cleaning, and improving the convenience of use.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] Please see Figure 1-4 An anti-clogging solenoid valve includes a valve body 1. An inlet pipe 2 and an outlet pipe 3 are connected to both sides of the valve body 1. The end of the inlet pipe 2 is a closed structure, with a sleeve 4 fixedly connected thereto. A cap 5 is provided at the top of the sleeve 4. A threaded joint is provided between the cap 5 and the sleeve 4, allowing the cap 5 to be rotated and screwed onto the top of the sleeve 4. An inlet pipe 6 is provided at the top of the cap 5, allowing gas to enter the sleeve 4 through the inlet pipe 6. The solenoid valve structure also includes a filter screen sleeve 7. The top edge of the filter screen sleeve 7 has an annular end 8. A retaining ring 9 is provided inside the port of the sleeve 4. When the filter screen sleeve 7 is inserted into the sleeve 4 from the top port, the annular end 8 of the filter screen sleeve 7 abuts against the retaining ring 9 inside the sleeve 4, supporting the annular end 8 and allowing the filter screen sleeve 7 to hang inside the sleeve 4. A pressure block 10 is provided on the inner wall of the cap 5. When the cap 5... When the cover 5 is screwed onto the top of the sleeve 4, the pressure block 10 can press against the top of the annular end 8, so that the position of the filter screen sleeve 7 inside the sleeve 4 can be kept fixed. When the exhaust gas enters the sleeve 4 through the inlet pipe 6, the exhaust gas will be filtered by the filter screen sleeve 7, so that the carbon deposits in the exhaust gas are intercepted by the filter screen sleeve 7 and remain in the sleeve 4. In addition, the inside of the cover 5 is rotatably connected to the first rotating shaft 11, and the bottom surface of the first rotating shaft 11 is connected to the brush plate 12. When the cover 5 is rotated and screwed... When connected to the sleeve 4, the bottom end of the first rotating shaft 11 extends into the filter screen sleeve 7 fixed inside the sleeve 4. At this time, the surface of the brush plate 12 can just touch the inner wall of the filter screen sleeve 7. The cover 5 is also equipped with a power component, which can drive the first rotating shaft 11 to rotate, thereby driving the brush plate 12 to rotate. During this process, the brush plate 12 can clean the carbon deposits attached to the inner wall of the filter screen sleeve 7, which can prevent the attached carbon deposits from clogging the filter screen sleeve 7.
[0022] During use, insert the filter sleeve 7 from the top port of the sleeve 4, so that the annular end 8 at the top of the filter sleeve 7 abuts against the retaining ring 9 on the inner side of the sleeve 4. Then, rotate and screw the cover 5 onto the top of the sleeve 4. At this time, the pressure block 10 can press against the annular end 8, fixing the filter sleeve 7 inside the sleeve 4. At the same time, the brush plate 12 at the bottom of the first rotating shaft 11 will also extend into the fixed filter sleeve 7 and abut against the inner wall of the filter sleeve 7. Connect the inlet pipe 6 and the outlet pipe 3 to the exhaust gas pipeline. After opening the valve body 1, the exhaust gas can enter the interior of the sleeve 4 through the inlet pipe 6. At this time, the filter sleeve 7 in the sleeve 4 can filter the exhaust gas, intercepting the carbon deposits in the exhaust gas in the filter sleeve 7. The filtered exhaust gas will enter the valve body 1 through the inlet pipe 2 and be discharged through the outlet pipe 3. To effectively prevent carbon deposits in the exhaust gas from entering the valve body 1 and adhering to the valve core inside the valve body 1, some of the intercepted carbon deposits will adhere to the inner wall of the filter screen sleeve 7. At this time, the power component can drive the first rotating shaft 11 to rotate, which will drive the brush plate 12 to rotate against the inner wall of the filter screen sleeve 7. During this process, the brush plate 12 can sweep off the carbon deposits adhering to the inner wall of the filter screen sleeve 7, thereby effectively preventing the adhering carbon deposits from clogging the filter screen sleeve 7, effectively reducing the frequency of removing the filter screen sleeve 7 for cleaning, and improving the convenience of use. When a lot of carbon deposits accumulate in the filter screen sleeve 7, the cover 5 can also be unscrewed from the top of the sleeve 4. At this time, the user can directly remove the filter screen sleeve 7 from the inside of the sleeve 4 to manually clean the carbon deposits accumulated inside the filter screen sleeve 7.
[0023] For further details, please refer to Figure 1-4 The power assembly includes a motor 13 mounted on the side wall of the cover 5, a second rotating shaft 14 connected to one end of the output shaft of the motor 13 and extending into the interior of the cover 5, and a bevel gear set 15 disposed between the ends of the second rotating shaft 14 and the first rotating shaft 11 and meshing with each other. The output shaft of the motor 13 can drive the second rotating shaft 14 to rotate, and the second rotating shaft 14 will drive the first rotating shaft 11 to rotate synchronously through the transmission action of the bevel gear set 15.
[0024] For further details, please refer to Figure 1-4 A sealing gasket 16 is provided on the bottom surface of the annular end 8. The sealing gasket 16 will undergo elastic deformation after being compressed. When the annular end 8 is pressed tightly onto the retaining ring 9 by the pressure block 10, the sealing gasket 16 can improve the sealing between the annular end 8 and the retaining ring 9, ensuring that the exhaust gas entering the sleeve 4 can be filtered by the filter screen sleeve 7, and will not leak directly into the sleeve 4 through the joint between the retaining ring 9 and the annular end 8.
[0025] For further details, please refer to Figure 1-4The bottom end of the annular end 8 is provided with a positioning pin 17, and the surface of the retaining ring 9 is provided with a positioning hole 18 corresponding to the positioning pin 17. When the annular end 8 and the retaining ring 9 come into contact, the positioning pin 17 can be aligned and inserted into the inner wall of the positioning hole 18. At this time, under the positioning action of the positioning pin 17 and the positioning hole 18, the relative rotation between the annular end 8 and the retaining ring 9 can be restricted, so that the filter sleeve 7 can be more stably fixed in the sleeve 4 and is not easy to shake or shift.
[0026] For further details, please refer to Figure 1-4 The outer surface of the cover 5 is fixedly provided with an anti-slip handle 19. Holding the anti-slip handle 19 can prevent the hand from slipping, thus making it easy to rotate and twist the cover 5 during the process of disassembling and assembling.
[0027] For further details, please refer to Figure 1-4 The brush plates 12 are connected in three groups at equal intervals to the surface of the first rotating shaft 11. The three groups of brush plates 12 can improve the cleaning efficiency of carbon deposits on the inner wall of the filter screen sleeve 7 during rotation. Each group of brush plates 12 is fixedly connected to the first rotating shaft 11 by two fixing rods 20, so that the connection between the brush plates 12 and the first rotating shaft 11 is firm and not easily deformed during rotation.
[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
