Description

Technical Field

[0001] This utility model relates to the field of three-way valve technology, and in particular to a three-way valve for carburetors. Background Technology

[0002] As a key component of the engine's fuel supply system, the carburetor's performance directly affects the engine's operating efficiency and stability. In the carburetor's fuel supply circuit, the three-way valve plays a crucial role in distributing fuel flow. However, most existing carburetor three-way valves suffer from inconvenient filter removal and replacement. Over time, the filter accumulates a large amount of impurities. If the filter is not replaced promptly and conveniently, these impurities will pass through and enter the carburetor, clogging the nozzles, air passages, and other precision components. This leads to poor atomization, an imbalanced fuel-air mixture, and consequently, a series of adverse consequences such as reduced engine power, increased fuel consumption, and excessive emissions. Furthermore, replacing the filter on traditional three-way valves often requires specialized tools, making the process complex and time-consuming, significantly hindering routine maintenance and increasing repair costs and downtime. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] The present invention adopts the following technical solution: a three-way valve for a carburetor, comprising a valve body and an inlet pipe, one end of the inlet pipe being fixedly connected to the valve body, a filter chamber being fixedly connected to the surface of the inlet pipe, a groove being formed on the surface of the filter chamber, a slot being formed at the bottom of the groove, a filter plate being inserted into the slot, a connecting plate being fixedly connected to the top of the filter plate, a fixing block being fixedly connected to the surface of the filter chamber, a screw being threadedly connected to the inside of the fixing block, a locking block being rotatably connected to the top of the screw, and an adjusting knob being fixedly connected to the bottom of the screw.

[0005] Preferably, there are two sets of locking blocks, which are symmetrically distributed on both sides of the center of the filter chamber surface. This improves the stability of the filter plate.

[0006] Preferably, a sealing gasket is provided between the connecting plate and the bottom of the groove. This improves the seal between the filter plate and the filter chamber, preventing leakage.

[0007] Preferably, a handle is fixedly attached to the surface of the connecting plate. This further improves the ease of removing the filter plate from inside the filter chamber.

[0008] Preferably, the surface of the adjustment knob is fixedly connected with anti-slip ribs, which are evenly distributed on the surface of the adjustment knob. This increases the friction between the hand and the adjustment knob, preventing slippage when the adjustment knob is turned.

[0009] Preferably, a limiting hole is formed on the surface of the connecting plate, and a limiting rod is fixedly connected to the lower surface of the locking block, with the limiting rod inserted inside the limiting hole. This serves to limit the locking block's movement, preventing it from rotating when fixing the filter plate and thus ensuring effective fixation.

[0010] Preferably, a slag discharge pipe is fixedly connected to the bottom of the filter chamber, and a sealing cap is threaded onto the surface of the slag discharge pipe. This facilitates the discharge of impurities accumulated in the filter chamber, making the cleaning of impurities filtered by the filter plate more convenient and efficient.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model incorporates a fixing block, a screw, an adjusting knob, and a locking block structure. When the oil flows through the inlet pipe and passes through the filter chamber, impurities in the oil are filtered by the filter plate, ensuring the oil flowing into the valve body remains pure. When the filter plate needs cleaning or replacement, the adjusting knob is turned, causing the screw to rotate within the fixing block and push the locking block upwards. The filter plate can then be removed from the filter chamber for cleaning or replacement. This design secures the filter plate to the filter chamber and facilitates disassembly and assembly of the filter plate, making it easier to clean and replace later. This further improves the convenience and efficiency of cleaning and replacing the filter plate.

[0013] 2. In this utility model, by setting up a slag discharge pipe and a sealing cover structure, when the impurities filtered by the filter plate accumulate in the filter chamber to a certain amount, the sealing cover is removed from the slag discharge pipe, and then the impurities in the filter chamber flow out from the slag discharge pipe, which facilitates the discharge of the impurities accumulated in the filter chamber, making the cleaning of impurities filtered by the filter plate more convenient and efficient.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-4 This utility model provides a technical solution: a three-way valve for a carburetor, including a valve body 1 and an inlet pipe 2. One end of the inlet pipe 2 is fixedly connected to the valve body 1. A filter chamber 3 is fixedly connected to the surface of the inlet pipe 2. A groove 4 is formed on the surface of the filter chamber 3, and a slot 5 is formed at the bottom of the groove 4. A filter plate 6 is inserted into the slot 5. A connecting plate 7 is fixedly connected to the top of the filter plate 6. A fixing block 10 is fixedly connected to the surface of the filter chamber 3. A screw 11 is threadedly connected to the inside of the fixing block 10. A locking block 12 is rotatably connected to the top of the screw 11. An adjusting knob 17 is fixedly connected to the bottom of the screw 11. There are two sets of locking blocks 12. The filter plates 6 are symmetrically distributed on both sides of the center of the surface of the filter chamber 3. This improves the stability of fixing the filter plate 6. A sealing gasket 9 is provided between the connecting plate 7 and the bottom of the groove 4. This improves the sealing between the filter plate 6 and the filter chamber 3 and prevents leakage. A handle 8 is fixedly connected to the surface of the connecting plate 7. This further improves the convenience of removing the filter plate 6 from the inside of the filter chamber 3. Anti-slip ribs 18 are fixedly connected to the surface of the adjusting knob 17. The anti-slip ribs 18 are evenly distributed on the surface of the adjusting knob 17. This increases the friction when the hand contacts the adjusting knob 17 and prevents slippage when turning the adjusting knob 17.

[0024] Example 2

[0025] Please see Figure 2-4 A limiting hole 13 is provided on the surface of the connecting plate 7. A limiting rod 14 is fixedly connected to the lower surface of the locking block 12. The limiting rod 14 is inserted into the limiting hole 13. This can limit the locking block 12 and prevent it from rotating when fixing the filter plate 6, so as not to affect the fixing effect of the filter plate 6. A slag discharge pipe 15 is fixedly connected to the bottom of the filter chamber 3. A sealing cover 16 is threaded on the surface of the slag discharge pipe 15. This facilitates the discharge of impurities accumulated in the filter chamber 3, making the cleaning of impurities filtered by the filter plate 6 more convenient and efficient.

[0026] Working principle: During use, the oil enters the filter chamber 3 through the inlet pipe 2. The filter plate 6 filters the oil, and the filtered oil enters the valve body 1 and then the carburetor. The sealing gasket 9 between the groove 4 and the connecting plate 7 improves the seal between the filter plate 6 and the filter chamber 3, preventing leakage. When the filter plate 6 needs to be cleaned or replaced, turn the adjustment knob 17. The adjustment knob 17 drives the screw 11 to rotate in the fixed block 10 and push the locking block 12 upward. Then, turn the locking block 12 and hold the handle 8 to remove the filter plate 6 from the slot 5 and groove 4 on the filter chamber 3 for cleaning or replacement. This achieves the cleaning and replacement of the filter plate. The filter plate 6 is fixed to the filter chamber 3, which also facilitates the disassembly and assembly of the filter plate 6, making it easier to clean and replace the filter plate 6 later. This further improves the convenience and efficiency of cleaning and replacing the filter plate 6. When the impurities filtered by the filter plate 6 accumulate in the filter chamber 3 to a certain amount, the sealing cover 16 is removed from the slag discharge pipe 15, and then the impurities in the filter chamber 3 flow out from the slag discharge pipe 15, which facilitates the discharge of the impurities accumulated in the filter chamber 3. This makes the cleaning of the impurities filtered by the filter plate 6 more convenient and efficient. When the locking block 12 fixes the filter plate 6, the limiting rod 14 at the bottom of the locking block 12 is inserted into the limiting hole 13 on the connecting plate 7 to prevent the locking block 12 from rotating.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
