A non-contact dynamic seal that uses a thread to prevent liquid leakage, also known as a thread seal. Usually, the thread is processed on the rotary shaft of the sealing part, and the liquid leaked during work fills the space contained in the thread and the shell, forming a "liquid nut". The direction of the thread on the shaft causes the "liquid nut" to move axially as the shaft rotates, prompting the liquid to constantly return to the high-pressure end. Spiral seal is suitable for occasions with large liquid viscosity, small pressure difference and medium speed. Basically not limited by the temperature of the liquid.
