[0003] However, during the transmission process, gas fuel often carries a large amount of water, and liquid often remains in the pipeline. The existing gas valves cannot discharge the residual liquid or separate the liquid carried in the gas, which affects the combustion effect. Utility Model Content

[0004] The utility model aims to provide a gas valve capable of discharging liquid, so as to solve the technical problems raised in the background technology.

[0012] The utility model of a gas valve capable of discharging liquid has the following advantages:

[0013] 1. The utility model is conducive to reducing the temperature inside the condensation box through the cooperation between the condensation plate and the refrigerant pipe, and can cool the gas. As the temperature decreases, the movement speed of the gas molecules slows down, and the interaction between the molecules is enhanced, resulting in a decrease in the distance between the gas molecules, so that the water vapor mixed in the natural gas will turn into liquid water after cooling, and under the action of multiple condensation plates, the residence time of the natural gas in the condensation box is extended, which is conducive to the liquefaction of the water vapor mixed in the natural gas, thereby ensuring the purity of the natural gas and improving the combustion effect of the natural gas. At the same time, it can effectively prevent the phenomenon of water vapor corroding the pipeline.

[0014] 2. When the water in the water collecting tank needs to be discharged, the slide plate is pressed by hand so that the slide plate squeezes the reset spring. At this time, the slide plate will push the sealing plug and the sealing plate up, thereby exposing the leakage port, and the water in the water collecting tank can be discharged. After the hand pressing the slide plate is released, the slide plate moves down under the elastic action of the reset spring, thereby allowing the sealing plug to enter the leakage port. At the same time, the bottom of the sealing plate is in close contact with the bottom inner wall of the water collecting tank, thereby achieving a good sealing effect, which can effectively prevent the leakage of natural gas, and can further prevent the leakage of natural gas by manually controlling the switch of the leakage port.

The natural gas enters through the air inlet pipe 2, and first enters the interior of the condenser box 6 through the air inlet 10 of the condenser box 6. The gas is cooled by the condensation plate 9. As the temperature decreases, the movement speed of the gas molecules slows down, and the interaction between the molecules increases, resulting in a decrease in the distance between the gas molecules, so that the water vapor mixed in the natural gas will turn into liquid water after cooling. After that, the natural gas is discharged from the condenser box 6 through the air outlet 11 of the condenser box 6, and continues to be conducted through the air outlet pipe 3, and the liquid water enters the lower part of the inner cavity of the condenser box 6 through the L-shaped mesh plate 14 under the action of gravity. The surface of the condensation plate 9 is provided with a plurality of equally spaced long openings 12, and the long openings 12 are vertically arranged. The condensation plate 9 is provided with a plurality of refrigerant tubes 13 equally spaced up and down, and the refrigerant tubes 13 are horizontally distributed. Through the setting of the long openings 12, the natural gas can move through each condensation plate 9, and under the action of the refrigerant tubes 13, it is helpful to reduce the temperature inside the condensation box 6, and under the action of multiple condensation plates 9, the residence time of the natural gas in the condensation box 6 is extended, which is helpful to liquefy the water vapor mixed in the natural gas, thereby ensuring the purity of the natural gas and improving the combustion effect of the natural gas. At the same time, it can effectively prevent the phenomenon of water vapor corroding the pipeline.

[0029] The inner cavity of the valve body 1 is provided with a guide channel 8 which is respectively connected with the condensate tank 6 and the water collecting tank 7. The setting of the guide channel 8 is conducive to the liquid water in the condensate tank 6 entering the water collecting tank 7 through the guide channel 8 and being collected. A liquid leakage port is provided at the middle part of the bottom of the inner cavity of the water collecting tank 7, and a sealing plug 18 is provided in the liquid leakage port. A sealing plate 19 is provided at the top of the sealing plug 18. A connecting rod 20 is provided at the bottom of the sealing plug 18.

The bottom of the water collecting tank 7 is provided with slide bars 21 on both sides of the connecting rod 20. A return spring 23 is sleeved on the slide bar 21. The return spring 23 is located between the slide plate 22 and the bottom of the water collecting tank 7. The diameter of the connecting rod 20 is smaller than the diameter of the leakage port, and the surface of the slide plate 22 is provided with a sliding hole slidably connected to the slide rod 21. When the water in the water collecting tank 7 needs to be discharged, the slide plate 22 is pressed by hand so that the slide plate 22 squeezes the return spring 23. At this time, the slide plate 22 will push the sealing plug 18 and the sealing plate 19 upward, thereby exposing the leakage port, and the water in the water collecting tank 7 can be discharged. After the hand pressing the slide plate 22 is released, the slide plate 22 moves downward under the elastic action of the return spring 23, so that the sealing plug 18 enters the leakage port. At the same time, the bottom of the sealing plate 19 is in close contact with the bottom inner wall of the water collecting tank 7, thereby achieving a good sealing effect, which can effectively prevent the leakage of natural gas. Moreover, by manually controlling the switch of the leakage port, the leakage of natural gas can be further prevented. A liquid level sensor 15 is provided on the inner wall of the water collecting tank 7, and an observation window 17 and an alarm flash light 16 are provided on the surface of the water collecting tank 7. When the water in the water collecting tank 7 reaches the threshold set by the liquid level sensor 15, the liquid level sensor 15 will send a signal to the alarm flash light 16, so that the alarm flash light 16 will work, thereby reminding the user to drain the water from the water collecting tank 7, which can effectively prevent the water collecting tank 7 from being filled with water. Under the action of the observation window 17, the user can also observe the water level inside the water collecting tank 7 at any time through the observation window 17.
