[0014] A method for using a zero-leakage sealed exhaust valve comprises the following steps: Step 1: shunt detection; the fluid flows into the valve body through the shunt pipe, and most of the fluid flows into the valve body through the vortex finder. Due to the conical guide port set on the guide shell, the fluid on the outside can easily enter the inside. Here, due to the trumpet-shaped opening of the shunt pipe, the flow channel on the top side of the shunt pipe is narrowed, causing the fluid flow rate to slow down and the pressure to increase. A small part of the fluid is affected by the pressure and enters the light-transmitting tube. Here, the state of the fluid flowing through is detected by the optical sensor between the laser diode and the phototransistor; Step 2, flow disturbance: When the fluid enters the guide shell through the light-transmitting tube, the fluid here pushes the vortex fan and the arc ring to make circular motion inside the valve body, and the hollow ball here is affected by the arc ring and makes circular motion, and the fluid outside the guide shell enters the inside through the conical guide port, and the fluid flowing in here disturbs the airflow inside the guide shell, breaking the laminar flow state of the fluid from bottom to top, and reducing the floating resistance of bubbles in the liquid; Step 3, reducing the floating resistance; during the rotation of the hollow ball, the heat-conducting ring and the filler on the outside thereof rotate accordingly, and the heat-conducting ring and the filler cooperate with the airflow on the outside of the guide shell to form a vortex to reduce the laminar flow phenomenon, and at the same time, the heating effect of the electric heating sleeve is used to reduce the viscosity of the water and reduce the resistance of the bubbles to float; Step 4, blocking the fluid; when a certain amount of liquid flows in, the hollow ball is displaced upward by buoyancy and squeezes the guide rod, and the guide rod slides with the arc groove inside the spherical diverter to drive the rotating disk to rotate at the bottom of the fixed disk, so that the breathable membrane on the rotating disk rotates and blocks the opening of the fixed disk. Here, the breathable effect of the breathable membrane can effectively block the liquid while allowing the gas to flow through, and then the gas enters the spoiler structure and flows out through the arranged pipe orifices. The spoiler structure here can reduce or even eliminate the vortex phenomenon caused by the rotation of the vortex finder of the incoming fluid, and reduce the noise generated by the high-speed flow of gas through the valve during operation through the silencer gasket.

[0015] The present invention has the following advantages: The present invention provides a zero-leakage sealed exhaust valve through improvement, which has the following improvements compared with similar devices: The zero-leakage sealed exhaust valve described in the present invention is provided with a diversion structure and a vortex finder, and the light sensor between the laser diode and the phototransistor is used to detect the state of the fluid flowing through, and the vortex finder drives the hollow ball to rotate to cooperate with the transparent tube and the guide shell to break the laminar flow state of the fluid from bottom to top, thereby reducing the floating resistance of bubbles in the liquid; at the same time, the hollow ball squeezes the guide rod so that the air permeability effect of the air permeable membrane can effectively block the liquid while allowing the gas to flow through, and then the exhaust structure can reduce or even eliminate the vortex phenomenon of the incoming fluid caused by the rotation of the vortex finder, and the noise generated by the high-speed flow of gas through the valve during operation is reduced by the silencer gasket.

[0027] See also Figures 1 to 7Compared with the first embodiment, the present invention is a zero-leakage sealed exhaust valve, and the present embodiment further includes: a heat-conducting ring 61 is fixedly installed on the outer side of the hollow ball 6 by adhesion; a filler 62 is fixedly installed on the inner wall of the heat-conducting ring 61 by bolts, and the filler 62 is composed of a honeycomb-shaped heat-conducting material; the heat-conducting ring 61 and the filler 62 are both made of lightweight materials; an electric heating sleeve 63 is fixedly installed on the middle side of the valve body 1, and an electric heating wire is arranged inside the electric heating sleeve 63.

[0028] Based on the above, the working principle of a zero leakage sealed exhaust valve is: First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation; Second, when the liquid flows through the valve body 1, the fluid flows to the inside of the valve body 1 through the shunt pipe 41, and most of the fluid flows to the inside of the valve body 1 through the vortex generator 7. Due to the conical guide port set on the guide shell 71, the fluid on the outside can easily enter the inside. Here, due to the trumpet-shaped opening of the shunt pipe 41, the flow channel on the top side of the shunt pipe 41 is narrowed, resulting in the flow rate of the fluid being slowed down and the pressure being increased. A small part of the fluid is affected by the pressure and enters the inside of the light-transmitting tube 42. Here, the state of the fluid flowing through is detected by the optical sensor between the laser diode 44 and the phototransistor 45. Here, the laser diode 44 and the phototransistor 45 can also monitor the flow of the liquid in real time during the flow of the gas, and can realize the intelligent detection of the valve body 1 through signal transmission; Third, when the fluid enters the guide shell 71 through the light-transmitting tube 42, the fluid here pushes the vortex fan 72 and the arc ring 73 to make a circular motion inside the valve body 1, and the hollow ball 6 here is affected by the arc ring 73 and makes a circular motion, and the fluid outside the guide shell 71 enters the inside thereof through the tapered guide port, and the fluid flowing in here disturbs the airflow inside the guide shell 71, breaking the laminar flow state of the fluid from bottom to top, and reducing the resistance of bubbles in the liquid to float up; during the rotation of the hollow ball 6, the heat-conducting ring 61 and the filler 62 outside thereof rotate accordingly, and the heat-conducting ring 61 and the filler 62 here form a vortex with the airflow outside the guide shell 71 to reduce the laminar flow phenomenon, and at the same time, the viscosity of the water is reduced by the heating effect of the electric heating sleeve 63, and the resistance of bubbles to float up is reduced; Fourth, when a certain amount of liquid flows in at the same time, the hollow ball 6 is displaced upward by buoyancy and squeezes the guide rod 55. The guide rod 55 slides with the arc groove inside the spherical diverter 54 to drive the rotating disk 52 to rotate at the bottom of the fixed disk 51, so that the breathable membrane 53 on the rotating disk 52 rotates and seals the opening of the fixed disk 51. Here, the breathable effect of the breathable membrane 53 can effectively block the liquid while allowing the gas to flow through. Then the gas enters the spoiler structure 25 and flows out through the arranged pipe orifice 22. Here, the spoiler structure 25 can reduce or even eliminate the vortex phenomenon caused by the rotation of the vortex finder 7 of the incoming fluid, and reduce the noise generated by the high-speed flow of gas through the valve during operation through the silencer gasket 24.

[0029] The present invention provides a zero-leakage sealed exhaust valve through improvement.
