[0002] In the fields of industrial production, food production, etc., it is necessary to mix gas into water, such as the production of carbonated soda, hydrogen-rich water, etc. When gas and water are mixed, the gas needs to be pressurized into the liquid, so as to increase the gas content in the water.

[0003] For example, the Chinese patent document with publication number CN220071274U discloses a hydrogen-rich water mixing device, including a tube body and a tube core, the tube body has an input port and an output port, the input port is connected to the water inlet and the hydrogen input pipe, and the output port is connected to the hydrogen-rich water output pipe; the tube core is arranged in the tube body, and a plurality of spiral holes are arranged in the tube core, and the spiral holes have at least one spiral cycle; the spiral holes penetrate the two ends of the tube core. The high-pressure water pump and the electrolyzer respectively input high-pressure water and electrolyzed hydrogen into the three-way valve, and after mixing through the three-way valve, they are pressed into one end of the tube body, divided by a plurality of spiral holes, and spirally transported to the other end of the tube body along the spiral holes, and the water output from each spiral hole impacts each other and then outputs the tube body. Under the high-speed impact of water, water will form water molecule clusters, and after the hydrogen bonds in the water molecule clusters are combined with each other, hydrogen can be wrapped between the water molecule clusters, and under normal circumstances, water will not form small-structured water molecule clusters without violent impact, thereby increasing the hydrogen content in the water.

[0004] In the above patent document, after water and hydrogen enter the tube body, the overall pressure will drop, thereby reducing the degree of mixing of hydrogen and water, resulting in the problem of low hydrogen content in water. Utility Model Content

[0005] The utility model aims to provide a water-gas mixing valve body structure to solve the problem that the gas content in water is low when the water-gas is mixed in the prior art.

[0007] Furthermore, the one-way valve is arranged closer to the water outlet end of the valve body.

[0008] Furthermore, the one-way valve includes a slider and a spring; a guide portion extends from one end of the spiral shaft, the slider is slidably sleeved on the guide portion, and the outer side of the slider is slidably matched with the inner side wall of the valve body; a plurality of through holes are provided on the slider; a limiting portion is provided at the end of the guide portion, the spring is provided between the limiting portion and the slider, and the spring pushes the slider to seal and fit with the end of the spiral shaft.

[0009] Furthermore, a slot is provided on the inner side surface of the end cover, and a key is provided on one side of the spiral shaft, and the key is locked in the slot.

[0010] Furthermore, the key is inserted into the slot, and the end of the key abuts against the end surface of the slot, so that a distance is formed between the end of the spiral shaft and the mouth of the joint.

[0011] The above one or more technical solutions in the water-gas mixing valve body structure provided by the embodiment of the utility model have at least the following technical effects:

[0012] The mixture of water and hydrogen enters the valve body and is transported to the other end in the spiral channel.

[0021] In one embodiment of the water-gas mixing valve structure of the utility model, please refer to Figure 1 to Figure 3The water-gas mixing valve body structure comprises a valve body 100, a spiral shaft 200 and a one-way valve 300. The valve body 100 is provided with a cavity, and the two ends of the valve body 100 are provided with two end covers 110, and the end covers 110 are provided with joints 111 extending outward, so that the water inlet pipe and the water outlet pipe can be connected respectively through the two joints 111. The spiral shaft 200 is arranged in the cavity, and the outer side of the spiral shaft 200 is provided with a spiral groove 201, and the outer side wall of the spiral groove 201 is sealed and fitted with the inner side wall of the valve body 100, so that the spiral groove 201 and the inner side wall of the valve body 100 form a spiral channel; the one-way valve 300 is arranged at one end of the spiral shaft 200, so that the water flow in the spiral channel is output in one direction, and the one-way valve 300 maintains a constant pressure of the water flow in the valve body 100. Specifically, the mixture of water and hydrogen enters the valve body 100 and is transported to the other end in the spiral channel. Since the one-way valve 300 is provided in the valve body 100 and the one-way valve 300 enables the valve body 100 to maintain a certain pressure, when water and hydrogen are mixed in the spiral channel, the hydrogen is more easily mixed with water through the effect of maintaining pressure, thereby increasing the hydrogen content in the water.

[0022] For further information, please refer to Figure 1 , the one-way valve 300 is arranged closer to the water outlet end of the valve body 100. In this embodiment, by arranging the one-way valve 300 at the end of the spiral shaft 200 closer to the water outlet, the water and gas entering the spiral channel are maintained at a constant pressure and transported at a constant pressure.

[0023] Further, refer to Figure 1 The one-way valve 300 includes a slider 310 and a spring 320; a guide portion 210 extends from one end of the spiral shaft 200, the slider 310 is slidably mounted on the guide portion 210, and the outer side of the slider 310 is slidably matched with the inner side wall of the valve body; a plurality of through holes are provided on the slider 310; a limit portion 211 is provided at the end of the guide portion 210, the spring 320 is provided between the limit portion 211 and the slider 310, and the spring 320 pushes the slider 310 to seal and fit the end of the spiral shaft 200. Therefore, when the mixture of water and hydrogen enters the spiral groove, when the pressure in the spiral groove reaches a certain level, the elastic force of the spring 320 is overcome to make the slider 310 slide, so that the water flow in the spiral groove can be output through the through hole.

[0024] Further, refer to Figure 3 The inner side of the slider 310 is also provided with a sealing ring 330. The sealing ring 330 can further prevent water from penetrating into the through hole, thereby ensuring air tightness and water pressure inside the spiral groove.

[0025] Further, refer to Figure 3The cross section of the sealing ring 330 is V-shaped, and the opening faces the spiral shaft 200. When there is no water pressure or the pressure is low in the spiral groove, the spring 320 pushes the slider 310 to fit the end of the spiral shaft 200, so that the sealing ring 330 can be adsorbed on the end surface of the spiral shaft, further improving the airtightness and avoiding the problem of water flow and hydrogen being output from the through hole when the slider 310 does not slide open.

[0026] Further, refer to Figure 1 and Figure 2 A slot 112 is provided on the inner side of the end cover 110, and a key 202 is provided on one side of the screw shaft 200. The key 202 is locked in the slot 112 to position the screw shaft 200, thereby preventing the screw shaft 200 from rotating in the valve body 100.

[0027] Further, refer to Figure 1 and Figure 2 The key 202 is inserted into the slot 112, and the end of the key 202 abuts against the end surface of the slot 112, so that a gap is formed between the end of the spiral shaft 200 and the mouth of the joint. Therefore, the pressurized water flow can smoothly enter the spiral groove 201, avoiding the end surface of the spiral shaft 200 from causing excessive obstruction to the water flow.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
