1. Electric square tee product introduction
Electric square tee is a kind of key control equipment used in fluid conveying system, widely used in chemical, petroleum, pharmaceutical, food processing and other industries. It realizes the control of fluid flow through the electric actuator, and has the characteristics of simple operation, good sealing performance and strong corrosion resistance.
2. Structural characteristics
Main structure
Valve body: usually made of stainless steel or other corrosion-resistant materials, with good pressure and corrosion resistance.
Spool: Driven by electric actuator, it moves in the valve body to realize the change of fluid flow direction.
Electric actuator: including motor, reducer, position sensor, etc., responsible for driving the movement of the spool and monitoring the position of the spool in real time.
Seals: such as O-rings, gaskets, etc., used to ensure the sealing performance of the valve in the closed state.
Control box: contains a controller, power module, etc., for receiving external signals and controlling the action of the electric actuator.
Feature
Easy operation: Remote or automatic control through electric actuator without manual intervention.
Good sealing performance: the use of high-quality seals to ensure that the valve in the closed state without leakage.
Strong corrosion resistance: the valve body and valve core are made of corrosion-resistant materials, suitable for various corrosive media.
Long service life: Reasonable design and high-quality materials ensure long service life and stable performance of the valve.
3. How it works
The working principle of the electric square tee is to change the flow direction of the fluid by driving the valve core in the valve body through the electric actuator. Specifically, when the electric actuator receives an external signal, it drives the spool to move in the specified direction. The movement of the spool changes the cross-sectional area of the fluid channel, thereby changing the flow direction of the fluid. At the same time, the position sensor will monitor the position of the spool in real time and feed the position information to the controller. The controller adjusts the output of the electric actuator according to the position information to ensure that the spool reaches the specified position accurately.
