AI Technical Summary
Technical Problem
Existing electronic intelligent gas valves have a complex structure, require additional guide structures that occupy space, and have complex electronic control systems.
Method used
An electromagnetic control device is adopted, which uses a magnetic conductor to guide the valve stem. The opening and closing of the valve stem is controlled by the magnetic attraction of the coil and the magnetic conductor, which simplifies the structure and reduces the space occupied.
Benefits of technology
This design achieves a compact gas valve, reducing space occupation, lowering power consumption, broadening power supply options, and simplifying valve body design.

Abstract
This application discloses an electromagnetic control device and a gas valve and gas control system having the same. The electromagnetic control device includes a valve stem, a valve seal, and an electromagnetic holding assembly. The valve seal is fixedly connected to or limited by the valve stem. The electromagnetic holding assembly includes a first magnetic conductor, a second magnetic conductor, and a coil. The first magnetic conductor is sleeved on the valve stem, and the coil is fixedly connected to or limited by the second magnetic conductor. The first magnetic conductor is closer to the second magnetic conductor than the valve seal. The valve stem is slidably inserted into the second magnetic conductor to move the valve seal closer to or away from the valve port of the gas valve. When the coil is energized, the second magnetic conductor and the first magnetic conductor are attracted, and the valve seal is in an open position away from the valve port. This electromagnetic control device consumes relatively little power.
