Description

Technical Field

[0001] This utility model relates to the field of carburetor solenoid valve technology, and in particular to a highly integrated carburetor solenoid valve. Background Technology

[0002] A solenoid valve is a type of valve that uses electrical energy flowing through a coil to generate electromagnetic attraction, which attracts the valve core (overcoming the spring or its own weight). It is divided into two types: normally open and normally closed. It is usually used to cut off the flow of substances such as oil, water and gas, and works with electrical equipment such as pressure and temperature sensors to achieve automatic control.

[0003] For example, the authorized announcement number "CN214196504U" is named a new type of electronically controlled carburetor solenoid valve for gasoline engines. Through the cooperation of the housing, slide groove, slider, spring, connecting rod, solenoid valve body, through hole, protective cover, fixing plate, first fixing block, limit plate, pressure plate, second fixing block, screw, nut, connecting line, moving rod, actuating block and closed slide rail, the carburetor solenoid valve has a certain protective function during use and transportation, avoiding damage from external forces. This achieves the purpose of good protection effect of the carburetor solenoid valve, greatly improving the efficiency and service life of the carburetor solenoid valve.

[0004] The above-mentioned and existing technologies have the following drawbacks: when the solenoid valve is connected to the carburetor, it is subjected to the elastic force of the spring, making the connection between the solenoid valve and the carburetor unreliable; the desiccant in the drying box is inconvenient to place, reducing work efficiency. Utility Model Content

The first housing has symmetrical upper and lower limiting blocks. The upper and lower ends of the second housing are provided with limiting grooves that match the limiting blocks. The limiting blocks and limiting grooves are slidably connected. A first cover plate is threadedly connected to the inner wall of the front part of the first housing. Multiple threaded holes are distributed in a circumferential array on the surface of the sealed bottom. Each of the multiple threaded holes is threadedly connected to a drying component. The front ends of the first housing and the second housing are fixed by a first fixing device, and the rear ends of the first housing and the second housing are fixed by a second fixing device.

[0008] Preferably, the drying assembly includes a sealing column, which is threadedly connected to a threaded hole. The front surface of the sealing column is provided with an installation cage, and the surface of the installation cage is provided with a plurality of first vent holes. The front end of the installation cage is threadedly connected with a second cover plate, and the surface of the second cover plate is provided with a plurality of second vent holes.

[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] Reference Figure 1-5 A highly integrated carburetor solenoid valve includes a first housing 1 and a second housing 2. The second housing 2 has a bottom seal 3 at its rear end. The second housing 2 is connected to a solenoid valve body 5 via a fixing bracket 4. A connecting line 6 is provided on the rear surface of the solenoid valve body 5, sliding through the bottom seal 3. The first housing 1 has symmetrically positioned limit blocks 7. The upper and lower ends of the second housing 2 each have limit grooves 8 that match the limit blocks 7. The limit blocks 7 and limit grooves 8 are slidably connected, allowing for smoother relative movement of the first housing 1 and the second housing 2 by sliding within the limit grooves 8. A first cover plate 9 is threadedly connected to the inner front wall of the first housing 1. Multiple threaded holes 10 are arranged in a circumferential array on the surface of the bottom seal 3, each threadedly connected to a drying component. The front ends of the first housing 1 and the second housing 2 are fixed by a first fixing device, and the rear ends of the first housing 1 and the second housing 2 are fixed by a second fixing device.

[0023] The drying assembly includes a sealing post 11, which is threadedly connected to a threaded hole 10. The front surface of the sealing post 11 is provided with a mounting cage 12, and the surface of the mounting cage 12 is provided with a plurality of first vent holes 13. The front end of the mounting cage 12 is threadedly connected to a second cover plate 14, and the surface of the second cover plate 14 is provided with a plurality of second vent holes 15. The rear surface of the sealing post 11 is provided with a rotating cap 16, and the cross-sectional shape of the rotating cap 16 is a regular hexagon. The regular hexagon shape makes it easy to use a wrench to tighten the rotating cap 16.

[0024] The first fixing device includes a first flange 17, which is disposed on the inner wall of the front part of the first housing 1. The first flange 17 is threadedly connected to the second housing 2 by a plurality of first bolts 18.

[0025] The second fixing device includes a second flange 19, which is disposed on the inner wall of the rear part of the first housing 1. The second flange 19 is threadedly connected to the second housing 2 by a plurality of second bolts 20.

[0026] A third flange 21 is provided on the outer rear surface of the first housing 1 in a ring shape, and mounting holes 22 are distributed in a circular array on the surface of the third flange 21. The mounting holes 22 facilitate the fixing of the first housing 1.

[0027] Working principle: The second fixing device is installed by sliding the second housing 2 to the rear end of the first housing 1, then the second bolt 20 passes through the second flange 19 and is threaded to the second housing 2, and then the first cover plate 9 is threaded to the inner wall of the front end of the first housing 1. This is the transport state of the solenoid valve. Figure 1 The first and second fixing devices are configured by unscrewing the first cover plate 9, then unscrewing the second bolt 20, sliding the second housing 2 to the front end of the first housing 1, and then threading the first bolt 18 through the first flange 17 and connecting it to the second housing 2. This is the installation state of the solenoid valve, which can then be connected to the carburetor. Figure 3 In summary, when this solenoid valve is connected to the carburetor, it will not be subjected to the elastic force of the spring, thus avoiding an unreliable connection between the solenoid valve and the carburetor. The first flange 17 and the first bolt 18 provided by the first fixing device securely fix the first housing 1 and the second housing 2, and there will be no mutual movement force between them and the solenoid valve body 5, ensuring that the connection and fixation between the solenoid valve and the carburetor are not affected by other components.

[0028] When installing or replacing the drying component, use a wrench to rotate the rotating cap 16 to disengage the sealing post 11 from the threaded hole 10. Then, unscrew the second cover plate 14, place the desiccant in the mounting cage 12, and screw the second cover plate 14 back onto the mounting cage 12. Finally, thread the sealing post 11 into the threaded hole 10. The desiccant dries the solenoid valve body 5 through the first vent 13 and the second vent 15, preventing the solenoid valve body 5 from getting damp. In summary, the desiccant in the mounting cage 12 of this solenoid valve is conveniently placed, improving work efficiency.
