Description

Technical Field

[0001] The utility model relates to the oil valve technology for stoves, in particular to an oil valve for liquid fuel stoves. Background Art

[0002] A liquid fuel stove is a portable stove device that uses liquid fuel for heating and cooking. It is a commonly used cooking tool in outdoor activities, camping, mountaineering and hiking, providing a convenient cooking solution. These fuels are usually carried in bottled form, which is easy to carry and store. The oil valve is a key component for controlling the flow of liquid fuel. It can control the flow of fuel from the storage container to the burner, ensuring that the firepower is adjustable and stable to meet different cooking needs.

[0003] In the prior art, some oil valves usually control the flow of fluid in cooperation with a sealing ring. However, as time goes by, the handle is turned too many times, causing more friction between the valve core and the sealing ring. This friction will accelerate the wear of the sealing ring, thereby reducing the service life of the sealing ring. Therefore, in view of the above shortcomings, an oil valve for a liquid fuel stove is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an oil valve for a liquid fuel stove, comprising a valve body 1, which is the shell of the entire oil valve, a limited block 2 is fixedly connected to the left side of the interior of the valve body 1, and a valve core 3 is movably connected to the interior of the limited block 2. The function of the limited block 2 is to limit the movement range of the valve core 3, to ensure that the valve core 3 will not fall out of the valve body 1 when rotating, thereby maintaining the stability and safety of the valve, the external thread of the valve core 3 is connected to the interior of the valve body 1 by this threaded connection, so that the valve core 3 can rotate and move, thereby opening or closing the oil circuit, a rotating component is fixedly connected to the left side of the valve core 3, and the rotating component includes a handle 4. This component allows the user to operate the position of the valve core 3 by rotating the handle 4, and the right end of the handle 4 is fixedly connected to the left side of the valve body 1, and an oil inlet 5 is provided on the right side of the valve body 1. It is the entrance for fuel to enter the oil valve, and an oil inlet pipe 6 is provided inside the right side of the valve body 1. The oil inlet pipe 6 extends from the oil inlet 5 to the inside of the valve body 1, and a sealing ring 7 is arranged inside the oil inlet pipe 6 to ensure that the fuel will not leak during the flow process, and the right side of the valve core 3 is in contact with the inside of the sealing ring 7.

[0024] Reference Figure 2 , Figure 4 and Figure 5 The top of the valve body 1 is provided with an oil outlet 8 as an outlet for the fuel to flow out of the oil valve. The design of this outlet ensures that the fuel can be smoothly output from the valve body 1 to other parts of the stove for combustion. The top of the valve body 1 is provided with an oil outlet pipe 9. The oil outlet pipe 9 is a pipe connecting the oil outlet 8 and the inside of the valve body 1. It is responsible for guiding the controlled fuel from around the valve core 3 to the oil outlet 8, so as to enter the combustion system. The inside of the oil outlet pipe 9 is provided with a sealing ring 2 10 to ensure that during the sealing period, the fuel cannot leak from between the oil outlets 8. The inside of the valve body 1 is provided with two sealing rings 3 11 to provide double sealing protection to ensure that the valve core 3 will not leak due to the fuel pressure during operation. The outside of the valve core 3 is in contact with the inside of the two sealing rings 3 11. This design not only ensures the mechanical stability of the valve core 3 during operation, but also effectively prevents the fuel from leaking through possible gaps.

[0025] Reference Figure 2 , Figure 4 and Figure 6The interior of the valve core 3 is provided with a receiving hole 12 to provide additional receiving space, and a strong spring 13 is arranged inside the receiving hole 12 to provide necessary pressure to help push the subsequent blocking ball 15 to make close contact with the sealing ring 2 10, and the interior of the receiving hole 12 is slidably connected to a limiting disk 14. The function of the limiting disk 14 is to serve as a supporting structure for the spring, and at the same time ensure that the pressure of the spring can be evenly transmitted to the blocking ball 15. One end of the strong spring 13 is fixedly connected to one side of the interior of the receiving hole 12, and the other end of the strong spring 13 is fixedly connected to one side of the limiting disk 14. The top of the limiting disk 14 is fixedly connected with a blocking ball 15. The design of the blocking ball 15 enables it to slide on the inner wall of the valve core 3, and according to the needs of fuel flow, through the action of the strong spring 13, the channel to the sealing ring 2 10 is blocked or opened, and the outside of the blocking ball 15 is slidably connected to an inner wall on one side of the valve core 3, and the outside of the blocking ball 15 is in contact with the inside of the sealing ring 2 10.

[0026] Working principle: First, during use, the user starts the opening and closing mechanism of the entire valve by twisting the handle 4. The handle 4 is connected to the valve core 3. By rotating the handle 4, the valve core 3 moves along the threaded path inside the valve body 1, and the limit block 2 is fixed in the valve body 1, providing a physical limit for the movement of the valve core 3 to prevent the valve core 3 from excessively moving from a predetermined position, thereby ensuring the stability and safety of the operation. When the valve core 3 moves downward, one end of the valve core 3 blocks the oil inlet 5 and is in close contact with the sealing ring 7, effectively closing the oil inlet pipe 6 and preventing further flow of fuel. Then, when the valve core 3 moves, it also drives the blocking ball 15 to move. Since the blocking ball 15 is under stress inside the valve body 1, when it moves to the oil outlet pipe 9 , it will move due to the rebound force generated by the strong spring 13 after being stressed, thereby blocking the oil outlet pipe 9 and contacting the sealing ring 2 10 to increase the sealing effect, and under the action of the strong spring 13 and the design of the blocking ball 15, the contact surface with the sealing ring 2 10 is optimized to ensure a more uniform pressure distribution, reduce the wear rate of the sealing ring 2 10, and enhance the sealing effect. When the valve core 3 is rotated upward, the blocking ball 15 will be driven to separate from the sealing ring 2 10, because the blocking ball 15 is spherical in shape, the outside is arranged in an arc shape, and under the elastic support of the strong spring 13, the blocking ball 15 can be separated from the inside of the oil outlet pipe 9 under the rotation of the valve core 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
