The use of lubrication in the gate valve is the basic condition to ensure the normal operation of the worm gear reducer, because the lubricating oil can form an oil film on the contact surface of the worm gear, thereby avoiding direct contact between metals and effectively reducing wear. This is for reducing wear, improving transmission efficiency, prolonging the service life of the worm gear reducer, and ensuring the smooth operation of the reducer.
