Technical Field

[0001] This utility model belongs to the field of gas valve technology, and in particular relates to a gas valve that can drain liquid. Background Technology

[0002] In the transmission and use of flammable gases such as natural gas and coal gas, when we are no longer using the gaseous fuel, we need to use gas valves to isolate the gas in the pipeline to prevent gaseous fuel leakage.

[0003] In the prior art, gaseous fuels often carry a large amount of water during transportation, and liquid often remains in the pipeline. Existing gas valves cannot drain the residual liquid or separate the liquid carried in the gas, which affects the combustion effect. Therefore, a liquid-draining gas valve is proposed to solve the above problems. Utility Model Content

A float ball is movably installed inside the gas-liquid separation chamber. A guide channel is inclinedly arranged on one surface of the gas-liquid separation chamber, and one end of the guide channel is connected to the interior of the gas-liquid separation chamber. A valve port is installed inside the guide channel to facilitate the collection of moisture carried during the transportation of gaseous fuel into the gas-liquid separation chamber, which is then discharged through the guide channel, achieving separate discharge of gas and liquid to ensure the combustion effect of the gas. A valve core is rotatably installed inside the valve body. A first valve seat is sleeved on one end of the valve body, and a second valve seat is sleeved on the other end of the valve body.

[0027] Please see Figures 1-4 As shown, this utility model is a gas valve capable of draining liquid, including a valve body 1 and a gas-liquid separation chamber 2. The gas-liquid separation chamber 2 is welded to the lower surface of the valve body 1, and the upper end of the gas-liquid separation chamber 2 is connected to the interior of the valve body 1. A float ball 201 is movably installed inside the gas-liquid separation chamber 2. A guide channel 202 is inclinedly provided on one surface of the gas-liquid separation chamber 2, and one end of the guide channel 202 is connected to the interior of the gas-liquid separation chamber 2. A valve port 203 is installed inside the guide channel 202 to facilitate the collection of moisture carried during the transportation of gaseous fuel into the gas-liquid separation chamber 2, and then discharged through the guide channel 202, realizing the separate discharge of gas and liquid, ensuring the combustion effect of the gas. A valve core 101 is rotatably installed inside the valve body 1. A first valve seat 102 is sleeved on one end of the valve body 1, and a second valve seat 103 is sleeved on the other end of the valve body 1.

[0028] An air inlet 104 is welded to one surface of the first valve seat 102, and an air outlet 105 is welded to one surface of the second valve seat 103. Locking ends 106 are welded to the periphery of both the first valve seat 102 and the second valve seat 103. A through hole is passed through one surface of the locking end 106. A fastening bolt 107 is slidably installed between the two through holes. A fastening nut 108 is screwed to one end of the fastening bolt 107.

[0029] A bracket 3 is welded to the upper surface of the valve body 1. The lower end of the bracket 3 is connected to the interior of the valve body 1. The upper surface of the bracket 3 has a claw-shaped structure. A fixed base 301 is welded to the upper surface of the bracket 3. The fixed base 301 has a frame structure.

At this time, the water carried in the gaseous fuel will gradually enter the gas-liquid separation chamber 2. When the liquid accumulates to a certain level, the float 201 floats in the gas-liquid separation chamber 2. When the float 201 floats, it leaks out of the guide channel 202 set on one side of the gas-liquid separation chamber 2, thereby facilitating the discharge of liquid from the valve port 203, realizing the separate discharge of gas and liquid, and ensuring the combustion effect of gas.
