[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 6 As shown, this application proposes a passive magnetically controlled gas valve for high-pressure gas transmission pipelines. Through the interaction of a magnetic control component 3 and a magnetic response switch 2, the valve body 1 controls the flow of gas. Specifically, the valve body 1, magnetic response switch 2, and magnetic control component 3 are configured. The magnetic response switch 2 is located inside the valve body 1, and the magnetic control component 3 is located outside the valve body 1, corresponding to the magnetic response switch 2. The valve body 1 includes a main pipe 11 and an inlet pipe 12 and an exhaust pipe 13 disposed thereon. The inlet pipe 12 is located on the side of the main pipe 11, and the exhaust pipe 13 is located at the end of the main pipe 11. The magnetic response switch 2 is located inside the main pipe 11, corresponding to the exhaust pipe 13, and the magnetic control component 3 is located at the end of the main pipe 11 furthest from the exhaust pipe 13, corresponding to the magnetic response switch 2.

[0033] The magnetic control component 3, located outside the valve body 1, interacts with the magnetic response switch 2, located inside the valve body 1, to block the exhaust pipe 13, thus opening and closing the air passage between the air compressor and the air-consuming equipment. This solution replaces the traditional electromagnetic switch or valve installed on the air supply line for opening and closing operations by using the magnetic response switch 2 in conjunction with the magnetic control component 3. This makes it more suitable for high-salt, high-humidity environments such as marine ranches, aiming to improve the equipment's corrosion resistance and service life while reducing maintenance costs.

[0034] In this embodiment, the diameter of both the intake pipe 12 and the exhaust pipe 13 is smaller than that of the main pipe 11. A converging section 14 is provided at the connection between the main pipe 11 and the exhaust pipe 13, and the diameter of the converging section 14 gradually decreases in the direction toward the exhaust pipe 13.

[0035] The main pipe 11 has a converging section 14 inside, whose diameter gradually decreases in the direction toward the exhaust pipe 13, forming a structure similar to a Venturi tube. This structure helps to create a low-pressure area in the converging section 14, thereby attracting the magnetic response switch 2. When the magnetic force control component 3 releases the attraction to the magnetic response switch 2, the low pressure of the converging section 14 of the main pipe 11 attracts the magnetic response switch 2 to block the exhaust pipe 13.

[0036] like Figure 6As shown, in the embodiment, the pipe diameter size of the air inlet pipe 12 and the air outlet pipe 13 is smaller than that of the main pipe 11, and the converging section 14 and the diffusion section 15 are sequentially arranged between the main pipe 11 and the air outlet pipe 13, and the pipe diameter of the converging section 14 and the diffusion section 15 gradually increases towards the main pipe 11 and the air outlet pipe 13, respectively.

[0037] The diffusion section 15 is additionally arranged after the converging section 14, so that the gas can gradually slow down and stabilize in the diffusion section 15 after being accelerated in the converging section 14; at this time, the design of the diffusion section 15 reduces the gas flow rate, and further enhances the pressure difference between the converging section 14 and the diffusion section 15, which helps to enhance the attraction force of the magnetic response switch 2 when the magnetic response switch 2 blocks the air outlet pipe 13, and the greater pressure difference helps to enhance the adhesion and sealing between the magnetic response switch 2 and the converging section 14.

[0038] As shown in Figure 4 , in the embodiment, the magnetic response switch 2 includes a piston body 21 in a tubular structure, a rubber sealing element 22 is arranged at one end of the piston body 21, and a first magnet 23 is arranged at the other end of the piston body 21; the pipe wall of the converging section 14 is in a conical surface structure, and the rubber sealing element 22 is arranged in a conical structure and cooperates with the pipe wall of the converging section 14.

[0039] The magnetic response switch 2 is arranged to interact with the magnetic force control assembly 3 through the first magnet 23 arranged thereon, the piston body 21 is in a tubular structure, which is convenient for sliding in the main pipe 11, and the rubber sealing element 22 is used to ensure the sealing property during the blocking process; when the magnetic force control assembly 3 removes the attraction force of the magnetic response switch 2, the magnetic response switch 2 is attracted to the converging section 14 due to the low pressure effect of the converging section 14 of the main pipe 11, so as to block the air outlet pipe 13.

[0040] Further referring to Figure 4 and Figure 5 , an embodiment of the magnetic force control assembly 3 is shown, the magnetic force control assembly 3 includes a control flap 31 and a second magnet 32 arranged thereon, the control flap 31 is hinged to the outer wall of the main pipe 11 through a spring hinge 36, and the second magnet 32 is arranged on the side of the control flap 31 facing the main pipe 11.

[0041] The magnetic force control assembly 3 controls the movement of the magnetic response switch 2 through the second magnet 32 arranged thereon, when it is needed to close the air valve, the second magnet 32 arranged on the control flap 31 is driven away from the bottom end of the main pipe 11 through the control flap 31, so as to remove the mutual attraction force between the first magnet 23 and the second magnet 32, once the magnetic attraction force is reduced to a certain extent, the magnetic response switch 2 is attracted to this position due to the low pressure effect of the converging section 14 of the main pipe 11, so as to block the air outlet pipe 13.

[0042] As shown in Figure 3Another embodiment of the magnetic force regulating assembly 3 is shown, the magnetic force regulating assembly 3 comprises a liquid control bottle 33 and a float ball 34 arranged in the shell 331 of the liquid control bottle 33, the shell 331 and the float ball 34 are both in tubular structure, a third magnet 35 is arranged at one end of the float ball 34 towards the main pipe 11, the mass of the float ball 34 and the third magnet 35 is greater than the attraction force between the first magnet 23 and the third magnet 35.

[0043] When the liquid level in the liquid control bottle 33 changes, the float ball 34 and the third magnet 35 thereon will also move correspondingly, so as to change the magnetic force interaction with the magnetic response switch 2. When the float ball 34 drops to a certain position, the attraction force between the third magnet 35 and the first magnet 23 decreases or disappears, the magnetic response switch 2 is attracted to the position due to the low pressure effect of the folding section 14 of the main pipe 11, and the exhaust pipe 13 is blocked.

[0044] The end of the air inlet pipe 12 and the exhaust pipe 13 is respectively provided with an air inlet joint and an air outlet joint, the air inlet joint is connected to the air outlet of the air compressor, and the air outlet joint is connected to the air inlet of the air equipment. The air inlet joint and the air outlet joint improve the universality and adaptability of the air valve.

[0045] It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model, various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
