Problems solved by technology

In the current Chinese patent, there is an actuator that uses bellows to realize the full shielding and sealing of the valve stem. The disadvantage is that the input shaft and output shaft of the valve driving torque are not in the same axis, and the rotation angle of the valve core will deviate during the opening and closing process of the ball valve. , affecting the sealing performance of the valve
Moreover, the movement track of the valve stem of the commonly used solenoid valve is mostly up and down, and the application of the rotary solenoid valve is less.

Embodiment Construction

[0017] combined with figure 1 The present invention is further described.

[0018] as attached figure 1 The figure shows a sealed actuator and a fully shielded valve containing this mechanism, including a fully shielded assembly, a fixed assembly, and a rotating assembly. The full shielding assembly includes a shielding sleeve, the shielding sleeve end cover, and a heat insulation bracket; the fixed assembly includes a fixed iron core and a fixed coil; the rotating assembly includes a rotating iron core and a rotating permanent magnet.

[0019] The rotating iron core is a hollow structure, positioned on the shaft shoulder of the valve stem and limited by the lock nut, and the rotating iron core and the valve stem are connected by a transmission key. The end cover of the shielding sleeve is sealed and fixedly connected with the upper end of the shielding sleeve, and the lower end of the shielding sleeve is sealed and fixedly connected with the upper end of the heat insulation...

Abstract

The invention relates to a sealing execution mechanism and a full-shielding valve with an electromagnetic driving mechanism arranged inside and including the sealing execution mechanism, and belongs to the technical field of fluid machines. The full-shielding valve comprises a full-shielding assembly, a stator and a rotor. The full-shielding assembly comprises a shielding sleeve, a shielding sleeve end cover and a heat insulation support. The full-shielding assembly can bear fluid pressure in a valve body, and a formed pressure bearing cavity isolates a valve rod and the interior of the valve body from the outside. A dynamic sealing point of the valve rod is eliminated, and full-shielding sealing is achieved. A rotary electromagnetic field generated when a stator coil is powered on and a magnetic field generated by a rotor permanent magnet interact, generated electromagnetic torque penetrates the full-shielding assembly to be transferred to the rotor in a non-contact manner, and the rotor directly drives the valve rod to rotate through a transmission key. Effective driving of the valve under the full-shielding sealing condition is achieved.

Description

technical field [0001] The invention relates to a sealing actuator and a fully shielded valve with a built-in electromagnetic drive mechanism, which belongs to the technical field of fluid machinery. Background technique [0002] There are many varieties and specifications of valves, which are important components in the process of fluid transportation and play a very important role in human production and life. In the devices and equipment for transporting and containing flammable, explosive, highly radioactive and highly toxic media, the requirements for valve sealing are more stringent. Valves currently on the market, such as ball valves, have a dynamic seal between the valve stem and the valve cover, where fluid is prone to leakage. The most direct and effective way to prevent this kind of leakage is to eliminate the dynamic seal leakage point. In the current Chinese patent, there is an actuator that uses bellows to realize the full shielding and sealing of the valve s...
