The conveying of liquids in equipment tanks is a complex and delicate process involving multiple technologies and knowledge. Pneumatic liquid conveying automatic control mechanisms are widely used in liquid conveying systems that require automatic control.

[0003] However, in the existing technology, the liquid in the equipment tank lacks automatic control function during the liquid transportation process, which cannot accurately control the liquid transportation, making the operation more complicated and affecting its use. Utility Model Content

It provides a pneumatic automatic control mechanism for transporting liquids.

[0007] A cover plate, which is used for mating and connecting with the equipment tank;

[0008] A linkage robotic arm, which is arranged in the shape of a ruyi (a traditional Chinese symbol of good fortune), is connected to the cover plate by fixing bolts, and a float upper limiter is installed at the bottom of the linkage robotic arm;

[0009] A short shaft is mounted at the bottom of the linkage robotic arm. A spring rocker arm is mounted on the surface of the short shaft. A long shaft is provided on one side of the spring rocker arm. The long shaft is connected to the spring shaft by a high-temperature spring.

[0010] A power guide rod, the bottom end of which is connected to a spring shaft, and the top end of which is connected to a power guide rod guide hole plate;

[0011] An intake and exhaust valve stem adjustment plate is provided. The top of the power guide rod guide hole plate is equipped with an intake and exhaust valve stem.

[0012] Furthermore, an air inlet is provided on the top side of the cover plate, and an air inlet valve assembly is provided inside the air inlet, the air inlet valve assembly being connected to the air inlet valve stem.

[0013] Furthermore, an exhaust port is provided on the air inlet side of the top side of the cover plate, and an exhaust valve assembly is provided inside the exhaust port, the exhaust valve assembly being connected to the exhaust valve rod.

[0014] Furthermore, the end of the fixing bolt passes through the top of the connecting rod robotic arm, and the end of the fixing bolt is threaded to the bottom side of the cover plate.

[0015] Furthermore, there are multiple float limiters, which are located on both sides of the bottom end of the connecting rod robotic arm.

[0016] Furthermore, there are two high-temperature springs, and the two high-temperature springs are symmetrically distributed about the spring connecting axis.

[0017] Furthermore, an actuator is installed at the bottom of the linkage robotic arm, and the bottom of the actuator is connected to a stainless steel high-temperature float via a float linkage.

[0018] Furthermore, the actuator is an adjusting bolt, and the end of the adjusting bolt passes through the bottom of the connecting rod robotic arm and connects to the top of the float connecting rod.

[0021] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0022] The positive and progressive effects of this utility model are as follows:

[0023] The aforementioned pneumatic liquid conveying automatic control mechanism is suitable for integration into various liquid conveying equipment. Integrated into the tank, the overall mechanism is connected to the tank via a mating flange. The tank should have one inlet and one outlet, and be equipped with a one-way valve. The equipment's positioning cover plate connects to the pressurized gas inlet as power. As the liquid level rises, a float rises, pulling up a high-temperature spring that triggers a power guide rod, pushing the inlet and outlet valve rods and adjusting plate. Simultaneously, the inlet and outlet valve rods are activated. The outlet valve rod pushes the outlet valve disc against the valve seat, forming a seal. Simultaneously, the inlet valve rod lifts the sealing valve core, allowing the pressurized gas to enter the sealed tank and pressurize the liquid for delivery to a higher level or over a longer distance. The collector works by lowering the float to a low position when the liquid level drops, causing the connecting rod to move under the tension of a high-temperature spring. The downward pull of the power guide rod then causes the intake and exhaust valve rod adjustment plate to move, thus actuating the intake and exhaust valve rods. The spherical valve core quickly forms a seal under gas pressure, while the exhaust valve rod moves down and disengages. As the liquid level rises, the gas in the tank is discharged. This process repeats automatically, thus achieving automatic control of the liquid. This facilitates the self-control of the transported liquid while ensuring a tight seal during the self-control process, meeting usage requirements. The intake valve seat sealing surface and the exhaust valve seat and exhaust valve disc are ground with special tools, giving the mechanism greater stability, a longer service life, and easier maintenance.

[0058] Working Principle and Function: The pneumatic liquid conveying automatic control mechanism is suitable for integration into various liquid conveying equipment. It is integrated into the tank body, with the overall mechanism and tank body connected by a mating flange. The tank body should have one inlet and one outlet, and be equipped with a one-way valve. The equipment positioning cover plate 1 has an air inlet 8 connected to pressurized gas as power. As the liquid level rises, the float rises with the liquid level, pulling up the high-temperature spring 15, which triggers the power guide rod 2, pushing the air inlet and exhaust valve rod adjusting plate 12. Simultaneously, it triggers the air inlet valve rod 10 and the exhaust valve rod 21. The exhaust valve rod 21 pushes the exhaust valve disc against the valve seat to form a seal. At the same time, the air inlet valve rod 10 lifts the sealing valve core, and the power gas enters the sealed tank, pressurizing and conveying the liquid to a high-level or long-distance collector. When the liquid... The float lowers to a low position, causing the connecting rod to move under the tension of the high-temperature spring 15. The downward pull of the power guide rod 2 causes the intake and exhaust valve rod adjusting plate 12 to move the intake and exhaust valve rod 21. The intake valve rod 10 moves down, and the spherical valve core quickly forms a seal under the action of gas pressure. The exhaust valve rod 21 moves down and disengages, and as the liquid level rises, the gas in the tank is discharged. This process repeats automatically, thereby realizing the automatic control of the liquid. This facilitates the automatic control of the transported liquid and ensures the sealing during the automatic control process, meeting the usage requirements. The sealing surface of the intake valve seat and the exhaust valve seat and exhaust valve disc are ground with special tools, giving the mechanism greater stability, longer service life, and easier maintenance.
