It consists of a cylinder, cyclone separator, high-efficiency defoaming screen, and drain valve. It is typically installed in front of a drying unit to remove moisture from the air through coarse filtration, thereby reducing the drying unit's workload.

[0004] Therefore, in order to prevent the gas from backflowing, which may cause the gas to re-enter the gas-liquid separator and be remixed, a one-way gas transmission gas-liquid separator output pipe can be designed to prevent the gas from backflowing. Utility Model Content

[0008] Preferably, a support foot is fixedly installed on the lower end of the separator tank body at the side of the discharge pipe outlet, and an electric control valve is fixedly installed on the surface of the discharge pipe outlet.
[0009] Preferably, the check ball is slidably connected to the movable cavity, and the inner diameter of the connecting groove is smaller than the movable cavity.
[0010] Preferably, the valve cavity and the separator tank body are connected to each other, the valve cavity and the piston are slidingly connected, and the inner diameter of the connection between the valve cavity and the separator tank body is smaller than the piston, so as to limit the movable space of the piston.

[0013] Beneficial effects of the utility model:
[0014] 1. This gas-liquid separator uses the pressure of the output gas to squeeze and push the check ball inside the check valve, causing the check ball to move to the upper side of the active cavity, thereby connecting the connecting grooves on both sides. When the gas output from the outlet pipe stops, the loss of gas pressure causes the check ball to fall back to the lower end of the active cavity due to gravity, blocking the connecting groove, thereby preventing gas backflow and optimizing the working capacity of the gas-liquid separator.
[0015] 2. When the pressure in the separator tank is too high, the pressure inside the tank squeezes the piston, causing the piston to drive the sliding rod and the sliding block to move upward. When the piston moves to the upper side of the pressure reducing port, the pressure reducing port is used to automatically reduce the pressure. At the same time, the sliding block moves upward to squeeze the pressure sensor, which cooperates with the pressure sensor to send a signal to the output device of the gas-liquid mixture, causing it to reduce its output. This helps to avoid excessive pressure in the separator tank, reduce damage to the equipment, and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to ( Figures 1-4 ), the utility model provides an embodiment: a gas-liquid separator, including a separator tank body 1, the right end of the surface of the separator tank body 1 is fixedly connected to the air outlet pipe 2, the surface of the air outlet pipe 2 is fixedly installed with a check valve 3, a movable cavity 4 is opened inside the check valve 3, and connecting grooves 5 are opened at both ends of the surface of the movable cavity 4, a check ball 6 is arranged inside the movable cavity 4, a pressure reducing valve 7 is fixedly installed on the upper end of the separator tank body 1, a valve cavity 8 is opened inside the pressure reducing valve 7, a return spring 9 is fixedly installed inside the valve cavity 8, a piston 10 is fixedly installed at the lower end of the return spring 9, a sliding rod 11 is fixedly installed on the upper end of the piston 10, a sleeve 12 is fixedly installed on the inner side of the return spring 9 inside the valve cavity 8, a pressure sensor 13 is fixedly installed inside the sleeve 12, a through groove 14 is opened at the lower end of the sleeve 12, the upper end of the sliding rod 11 extends to the interior of the sleeve 12 and is fixedly installed with a sliding block 15, and a pressure reducing port 16 is fixedly connected to the surface of the pressure reducing valve 7.
[0023] Please refer to ( Figure 1-Figure 2 ), in this embodiment, the left end of the surface of the separator tank body 1 is fixedly connected with an air inlet pipe port 17, the lower end of the separator tank body 1 is fixedly connected with a liquid discharge pipe port 18, the lower end of the separator tank body 1 is located on the side of the liquid discharge pipe port 18 and a support foot 19 is fixedly installed, and the surface of the liquid discharge pipe port 18 is fixedly installed with an electric control valve 20, the check ball 6 is slidably connected to the movable cavity 4, the inner diameter of the connecting groove 5 is smaller than the movable cavity 4, and the air pressure of the output gas is used to squeeze and push the check ball 6 inside the check valve 3, so that the check ball 6 moves to the upper side of the movable cavity 4, thereby connecting the connecting grooves 5 on both sides, and when the air outlet pipe port 2 stops supplying gas, the check ball 6 falls back to the lower end of the movable cavity 4 due to gravity due to the loss of air pressure, blocking the connecting groove 5, thereby achieving the purpose of blocking gas reflux, which is beneficial to optimizing the working capacity of the gas-liquid separator.
[0024] Please refer to ( Figure 1 、 Figure 3 and Figure 4), in this embodiment, the valve chamber 8 and the separator tank body 1 are connected to each other, the valve chamber 8 and the piston 10 are slidably connected, the sliding block 15 and the sleeve 12 are slidably connected, the sliding rod 11 and the through groove 14 are slidably connected, and the pressure reducing port 16 is fixedly connected to an external recovery pipe, and the inner diameter of the through groove 14 is smaller than the sliding block 15. When the pressure of the separator tank body 1 is too high, the piston 10 is squeezed by the pressure in the tank, so that the piston 10 drives the sliding rod 11 and the sliding block 15 to move upward, and when the piston 10 moves to the upper side of the pressure reducing port 16, the pressure reducing port 16 is used to automatically reduce the pressure, and at the same time the sliding block 15 moves upward to squeeze the pressure sensor 13, and cooperates with the pressure sensor 13 to send a signal to the output device of the gas-liquid mixture to reduce its output, which is beneficial to avoid excessive pressure in the separator tank body 1, reduce damage to the equipment, and extend its service life.
[0025] During operation, the material is first loaded from the air inlet pipe 17, and the gas-liquid separation operation is performed on it through the separator tank body 1, and then the separated gas is output from the air outlet pipe 2, and the air pressure of the output gas is used to squeeze and push the check ball 6 inside the check valve 3, so that the check ball 6 moves to the upper side of the movable cavity 4, thereby connecting the connecting grooves 5 on both sides. When the air outlet pipe 2 stops supplying gas, due to the loss of air pressure, the check ball 6 falls back to the lower end of the movable cavity 4 due to gravity, blocking the connecting groove 5, thereby preventing gas backflow. When the pressure of the separator tank body 1 is too high, the piston 10 is squeezed by the pressure in the tank, so that the piston 10 drives the sliding rod 11 and the sliding block 15 to move upward, and when the piston 10 moves to the upper side of the pressure reducing port 16, the pressure reducing port 16 is used to automatically reduce the pressure, and at the same time the sliding block 15 moves upward to squeeze the pressure sensor 13, and cooperates with the pressure sensor 13 to send a signal to the output device of the gas-liquid mixture to reduce its output.
[0026] Through the above steps, the air pressure of the output gas is used to squeeze and push the check ball 6 inside the check valve 3, so that the check ball 6 moves to the upper side of the movable cavity 4, thereby connecting the connecting grooves 5 on both sides. When the gas outlet 2 stops supplying gas, due to the loss of air pressure, the check ball 6 falls back to the lower end of the movable cavity 4 due to gravity, blocking the connecting groove 5, so as to solve the problem that the separated gas is prone to backflow, thereby causing the gas to re-enter the gas-liquid separator and be remixed.
