Embodiment 1

[0036] See Figures 1 to 4. The electromagnetic regulating valve of the present invention adopts the coaxial connection of the rotor type electromagnetic driving mechanism and the butterfly valve regulating mechanism.

[0037] The rotor type electromagnetic drive mechanism mainly includes a stator core 1, a stator coil 2 sleeved on the stator core 1, a rotor core 3 located in the stator core 1, and a rotor shaft 4 fastened to the rotor core 3, The rotor rotating shaft 4 is supported by the bearing 16 and the valve body 11, and the rotor can rotate in the stator. Rotor spring pin 5 is arranged on the rotor, and stator spring pin 7 is arranged on the stator, and back-moving spring 6 is housed between two spring pins, and rotor rotates to starting point under the action of back-moving spring 6 . When the stator coil 2 is supplied with a certain current, the rotor is driven by the electromagnetic force and rotates to the end point against the force of the return spring 6 . The gr...

Embodiment 2

[0048] See Figure 5. The valve body 11 of the electromagnetic regulating valve of the present invention can be made into a frustum-shaped plug-in installation structure, and used in conjunction with the socket-type valve seat 20 with a tapered hole. On the upper bracket or the upper end cover 9 of the rotor type electromagnetic drive mechanism, there is a shaft hole at the corresponding rotor shaft 4, and the rotor shaft 4 upper end stretches into the shaft hole.

Embodiment 3

[0050] See Figure 6. The valve body 11 of the electromagnetic regulating valve of the present invention is not only made into various plug-in installation structures, but also can be directly made into pipe joints connected with the valve body at both ends of the flow channel 13 of the valve body. The rotor rotating shaft 4 can also be sealed by a radial seal ring 21 in addition to being sealed by an axial seal ring or a seal gasket 17 .

Abstract

A small-sized rotor type electromagnetic regulating valve and method of use thereof, comprising rotor type electromagnetic driving mechanism and butterfly type valve regulating mechanism in coaxial connection, wherein the electromagnetic driving mechanism includes a stator, a rotor arranged in the stator and a rotor return spring, the valve regulating mechanism includes a valve body and a valve plate. The invention realizes simple structure, sensitive opening and closing, high resolution factor, small return difference, accurate valve position and good linearity.

Description

technical field [0001] The present invention relates to a control valve, in particular to a small rotor type electromagnetic control valve and its use method. The control valve is suitable for use as an actuator in a low pressure and small flow automatic control system, especially in a 10KW-80KW constant temperature gas water heater or Automatic regulation for gas in heaters. Background technique [0002] At present, the electronically controlled valves used for automatic control mainly include electromagnetic switch valves and electric regulating valves. Although the former is simple in structure, it generally cannot be used for adjustment; the latter is adjustable, but generally has a more complicated structure. [0003] No. 90222664.9 Chinese Utility Model Patent "Rotary Solenoid Valve" discloses a multi-pole cock type electromagnetic regulating valve. This valve "will need to overcome a large frictional moment when the rotor drives the spool to rotate", so "the electro...
