Description

Technical Field

[0001] The utility model relates to the technical field related to solenoid valve protection, and in particular to a solenoid valve protection device and a solenoid valve. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulics or pneumatics. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions in the control system. The most commonly used are one-way valves, safety valves, directional control valves, speed regulating valves, etc.

[0003] After searching, a solenoid valve protection device and a solenoid valve with the publication number CN215214972U were found, which include a first direct-controlled solenoid valve, a second direct-controlled solenoid valve and an automatic switching switch electrical appliance. The second direct-controlled solenoid valve is installed horizontally on one side of the first direct-controlled solenoid valve, and the automatic switching switch electrical appliance is installed at the top center between the first direct-controlled solenoid valve and the second direct-controlled solenoid valve. The automatic switching switch electrical appliance and the first direct-controlled solenoid valve and the second direct-controlled solenoid valve are electrically connected through connecting wires. The automatic switching switch electrical appliance realizes automatic switching and power supply of the first electromagnetic coil and the second electromagnetic coil, which can make the first direct-controlled solenoid valve and the second direct-controlled solenoid valve work alternately while ensuring pipeline cut-off, giving the first electromagnetic coil and the second electromagnetic coil a certain power-off time, which can effectively prevent the electromagnetic coils from overheating, heating up or even damage caused by too long power-on time.

It is necessary to remove the connecting pipe from the solenoid valve and clean it manually, which is time-consuming and labor-intensive. In addition, the flow rate cannot be affected in time, which affects the normal use of the solenoid valve. Utility Model Content

[0027] like Figure 1-4 As shown, this embodiment provides a protection device for a solenoid valve, comprising:

[0028] The protection mechanism 4 includes a fixing frame 401, an inner wall of the fixing frame 401 is provided with a mounting groove 403, an outer wall of one side of the fixing frame 401 is provided with a corresponding groove 404 connected to the mounting groove 403, and a protective cover 402 is fixedly connected to the outer wall of the fixing frame 401, and the inner cavity of the protective cover 402 is hollow;

[0029] The outer gear ring 405 is supported by the mounting groove 403, the gear 406 is meshed with the outer gear ring 405 through the corresponding groove 404, and the fixing frame 401 is protected by the protective cover 402 to prevent the fluid from flowing out of the corresponding groove 404;

[0030] The inner cavity of the protective cover 402 is rotatably connected to a gear 406, and the outer wall of the gear 406 is meshed with an outer gear ring 405, and the outer gear ring 405 is rotatably connected to the inner wall of the mounting groove 403;

[0031] The outer gear ring 405 is driven to rotate by the gear 406;

[0032] The outer wall of the gear 406 passes through the protective cover 402 and is fixedly connected to a turning handle 407. The outer wall of the outer gear ring 405 near the connecting port is fixedly connected to three connecting rods 408 at equal intervals around the circumference. The outer wall of the connecting rod 408 is fixedly connected to a cleaning rod 409.

[0033] The gear 406 is driven to rotate by the turning handle 407, and the outer gear ring 405 rotates and drives the cleaning rod 409 through the connecting rod 408 to clean the inlet and outlet;

[0034] Working principle: through the gear 406, outer gear ring 405, turning handle 407, and cleaning rod 409, the turning handle 407 is manually driven to rotate, the turning handle 407 drives the gear 406 to rotate, the gear 406 drives the outer gear ring 405 to rotate, and when the outer gear ring 405 rotates, it drives the connecting rod 408 to rotate, and the connecting rod 408 drives the cleaning rod 409 to clean the inlet and outlet of the main body 1 in time, preventing impurities from adhering to the inlet and outlet and causing blockage during long-term use, and the blockage can be cleaned in time;

[0035] This step ensures the flow rate of the inlet and outlet of the solenoid valve and ensures the normal use of the solenoid valve.

[0036] like Figure 1-4 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes a solenoid valve, including:

[0037] The main body 1, the fixing frame 401 is fixedly connected to the inlet and outlet ends of the main body 1;

[0038] The connecting pipes to be connected are fixedly connected by the fixing frame 401;

[0039] The support mechanism 2 includes a connecting frame 201 fixedly connected to the outer wall of the bottom of the main body 1. Sleeves 202 are symmetrically fixedly connected to the two sides of the bottom of the connecting frame 201. A movable frame 203 is slidably connected to the inner cavity of the sleeve 202. A synchronization frame is fixedly connected between the two movable frames 203. Mounting holes are opened through the sleeve 202, and fixing holes are opened at equal intervals on the outer wall of the movable frame 203.

[0040] The main body 1 is supported by the connecting frame 201, the movable frame 203 is retractable by the sleeve 202, the connecting frame 201 is supported by the movable frame 203, and the two movable frames 203 are synchronized by the synchronization frame;

[0042] The connecting tube 301 supports the rotating rod 302. When the rotating rod 302 rotates out of the connecting tube 301, the connecting spring 303 rebounds, causing the pushing frame 304 to return to its original position, causing the limiting ball 306 to return to its original position, and causing the connecting tube 301 to be separated from the sleeve 202.

[0043] The end of the connecting spring 303 is fixedly connected to the push frame 304, the end of the connecting tube 301 is penetrated by a limit hole 305, the inner wall of the limit hole 305 is slidably connected to the limit ball 306, and the end of the connecting tube 301 is fixedly connected to the limit frame 307;

[0044] The connecting spring 303 is driven to move by the rotating rod 302, and the pushing frame 304 is driven by the connecting spring 303 to push the limiting ball 306 out of the limiting hole 305, so that the sleeve 202 and the movable frame 203 are fixed, and the limiting ball 306 is limited by the limiting frame 307.

[0045] Working principle: After the main body 1 is fixedly connected to the connecting pipe and the main body 1 is fixedly placed on the platform, the movable frame 203 is moved up and down from the sleeve 202 to adjust the height of the main body 1 so that the mounting hole and the fixing hole coincide with each other. After the adjustment is completed, the connecting tube 301 is inserted into the mounting hole, and the rotating rod 302 is rotated. The rotating rod 302 drives the connecting spring 303 to extend into the connecting tube 301, and the connecting spring 303 drives the pushing frame 304 to move. The pushing frame 304 moves until it contacts and pushes the limiting ball 306, so that the limiting ball 306 extends from the limiting hole 305 and contacts the sleeve 202, thereby fixing the position of the sleeve 202 and the movable frame 203, thereby stably adjusting the height of the main body 1.

[0046] This step can be adapted to different working environments.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
