[0002] In fields such as industrial and mining, petroleum, water conservancy, and fire protection, electric valves control the flow rate, flow direction, pressure, temperature, etc. of flowing fluid media. There are mainly three types of forces for valve operation: thrust, torque, and edge tension. Among them, the valve with a linear thrust action has a trapezoidal thread on the lifting rod. By controlling the nut at the top of the valve through an electric valve device, the power of the motor rotation is converted into linear motion, thereby controlling the lifting of the valve body.

[0003] Currently, the electric valves on the market are all integrated. Due to the high usage frequency of electric valves, and there is no device inside the electric valve that can lubricate the threaded part, it leads to wear at the threaded part after long-term use of the electric valve, thereby affecting the use of the electric valve and reducing work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric valve with a lubricating mechanism, achieving the purpose that the mechanism can circularly lubricate the inside of the valve and is convenient for replacing the connected hose.
