Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a leakage-proof carburetor electromagnetic valve. Background Art

[0002] The carburetor solenoid valve is a key automotive component. Its function is to immediately disconnect the carburetor idle oil circuit when the engine is turned off, thereby stopping the engine from running. This function is achieved through linkage with the ignition switch, that is, when the ignition switch is turned on, the solenoid valve is also turned on;

[0003] After checking the public (announcement) number: CN217208202U, a leak-proof pneumatic solenoid valve is disclosed. This technology discloses "through the movable connection of the fixed sleeve on the surface of the connecting pipe, it is convenient to protect the connection of the connecting pipe, and at the same time, through the threaded connection between the screw and the screw sleeve, it is convenient to drive the first sealing plate downward to seal and fix the connection. Because the first spring applies elastic force to the second sealing plate and improves the sealing effect, and at the same time, the second spring applies elastic force to the limit ring" and other technical solutions, it has "convenient to drive the limit rod to limit and fix the position of the torsion disk, avoid its arbitrary rotation, affect the sealing of the connection, and solve the problem that the connection between the current pneumatic solenoid valve and the external pipeline is prone to leakage" and other technical effects;

[0004] Once the particulate impurities that may be carried in the fluid enter the solenoid valve directly without being filtered, they may cause friction with the core components such as the valve core and valve seat. This friction not only increases the wear rate of these components, but in severe cases may even cause the valve core to get stuck or the valve seat to leak, thereby interfering with the normal operation of the solenoid valve. In addition, these impurities may also block the flow channel of the solenoid valve, making it impossible for the fluid to pass smoothly, thereby reducing the performance of the solenoid valve or even completely losing its function. Therefore, ensuring that the interior of the solenoid valve is clean and free of impurities is crucial to preventing the solenoid valve from leaking. Utility Model Content

[0008] The fixing assembly comprises three mounting heads which are circumferentially distributed inside the ring frame and are slidably installed through the mounting heads. A stopper is fixed to the inner end of the mounting head. An arc ring is arranged at the front end of the ring frame. A dial head is fixed to the outer surface of the arc ring. Three circumferentially distributed connecting pieces are fixed to the inner surface of the arc ring. A positioning block is fixed to the rear end of the connecting piece.

[0012] Preferably, the filter assembly further comprises three limiting frames which are fixed and distributed circumferentially inside the ring frame, and the spring sheets are located in the limiting frames.

[0014] Beneficial Effects

[0017] (2) When the fuel enters the solenoid valve through the connecting mechanism, it can be filtered by the filtering mechanism to prevent impurities in the fuel from entering the interior of the solenoid valve and to prevent impurities from blocking the channel of the solenoid valve, making it impossible for the fuel to flow normally and causing the performance of the solenoid valve to deteriorate.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a technical solution for a leak-proof carburetor solenoid valve: a leak-proof carburetor solenoid valve, comprising a solenoid valve 1, a connecting mechanism 2 is provided at a liquid inlet on a valve body of the solenoid valve 1, a filtering mechanism 3 is provided on the connecting mechanism 2 and is used to filter impurities in the fuel entering the solenoid valve 1 from the connecting mechanism 2, and the filtering mechanism 3 comprises:

[0027] The filter assembly 31 comprises a ring frame 311 mounted on the connecting mechanism 2, and a filter screen 312 is installed inside the ring frame 311;

[0028] The fixing assembly 32 includes three mounting heads 321 which are circumferentially distributed inside the ring frame 311 and are slidably installed therethrough. A stopper 322 is fixed to the inner end of the mounting head 321. An arcuate ring 323 is provided at the front end of the ring frame 311. A dial head 324 is fixed to the outer surface of the arcuate ring 323. Three circumferentially distributed connecting members 325 are fixed to the inner surface of the arcuate ring 323. A positioning block 326 is fixed to the rear end of the connecting member 325. A spring sheet 33 is sleeved and installed on the mounting head 321.

[0029] In this embodiment, the filter mechanism 3 is installed into the interior of the connecting mechanism 2, and the mounting head 321 is aligned with the mounting hole 23, and then the dial head 324 is turned to drive the arc ring 323 to rotate clockwise. The arc ring 323 drives the positioning block 326 through the connecting piece 325, and the positioning block 326 pushes the stopper 322 to drive the mounting head 321 to extend outward so that it is inserted into the interior of the mounting hole 23. At the same time, the spring sheet 33 rebounds to give the stopper 322 a reverse force, so that the stopper 322 squeezes the positioning block 326 to fix it, thereby fixing the filter mechanism 3 in the interior of the connecting mechanism 2, so that when the fuel enters the solenoid valve 1 through the connecting mechanism 2, it can be filtered through the filter mechanism 3; and, when disassembling the filter mechanism 3, it is only necessary to turn the dial head 324 to drive the arc ring 323 to rotate counterclockwise.

[0030] Specifically, the fixing assembly 32 further includes a baffle 327 fixed to one end of the baffle seat 322 .

[0033] In this embodiment, when the positioning block 326 moves toward the stopper 322 , the arc surface 329 on the positioning block 326 contacts the inclined surface 328 on the stopper 322 , thereby smoothly pushing the stopper 322 to move and avoiding interference and jamming.

[0034] Specifically, the filter assembly 31 further includes three arc-shaped slots 313 circumferentially distributed at the front end of the ring frame 311 , and the connecting member 325 is located inside the arc-shaped slots 313 .

[0035] In this embodiment, the movement of the connecting member 325 is limited and guided by the arc-shaped slot 313 .

[0036] Specifically, the filter assembly 31 further includes three limiting frames 314 fixed on the inner circumference of the ring frame 311 , and the spring sheet 33 is located in the limiting frames 314 .

[0038] Specifically, the connecting mechanism 2 includes an inner joint 21 fixed to the liquid inlet of the solenoid valve 1, and the ring frame 311 is installed inside the inner joint 21, the front end of the inner joint 21 is provided with an outer joint 22, and the inner diameter of the outer joint 22 is larger than the inner diameter of the inner joint 21, the inner wall of the inner joint 21 is provided with three circumferentially distributed mounting holes 23 and matched with the mounting head 321, and the inner wall of the inner joint 21 is fixed with a ring seat 24.

[0039] In this embodiment, the inner diameter of the outer joint 22 is larger than the inner diameter of the inner joint 21 , so that the filter mechanism 3 can be easily removed from and loaded into the connecting mechanism 2 , and when the filter mechanism 3 is loaded into the connecting mechanism 2 , the filter mechanism 3 is limited by the ring seat 24 .

[0040] The working principle and use process of the utility model are as follows: first, the filter mechanism 3 is installed into the interior of the connecting mechanism 2, and the filter mechanism 3 is limited by the ring seat 24, and the mounting head 321 is aligned with the mounting hole 23, and then the dial head 324 is turned to drive the arc ring 323 to rotate clockwise, and the arc ring 323 drives the positioning block 326 through the connecting piece 325, and the positioning block 326 pushes the stop seat 322 to drive the mounting head 321 to extend outward so that it is inserted into the interior of the mounting hole 23, and at the same time, the spring sheet 33 rebounds to give the stop seat 322 a reverse force, so that the stop seat 322 squeezes the positioning block 326 to fix it, thereby fixing the filter mechanism 3 in the interior of the connecting mechanism 2, so that when the fuel enters the solenoid valve 1 through the connecting mechanism 2, it can be filtered by the filter mechanism 3; and, when disassembling the filter mechanism 3, it is only necessary to turn the dial head 324 to drive the arc ring 323 to rotate counterclockwise.
