Description

Technical Field

[0001] The utility model relates to the technical field of electric valves, and specifically relates to an electric valve capable of adjusting water flow. Background Technique

[0002] A globe valve, also known as a stop valve, belongs to a forced-sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. When the medium enters the valve from below the valve flap, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem needs to be large, otherwise the valve stem will be bent. It is divided into three types according to the connection method: flange connection, screw connection, and welding connection. Since the appearance of self-sealing valves, the flow direction of the medium in the globe valve has changed to enter the valve cavity from above the valve flap. At this time, under the action of the medium pressure, the force to close the valve is small, and the force to open the valve is large, and the diameter of the valve stem can be correspondingly reduced. Since the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable cutting function, and since the change of the valve seat port is proportional to the stroke of the valve flap, it is very suitable for the regulation of flow rate.

[0003] An electric valve is to add a motor to the globe valve to control the valve core to achieve the control of the water flow size. The connecting components between the existing electric valve motor and the valve body are mostly exposed outside. In different working environments, they may not be able to withstand long-term water vapor erosion and oxidation, reducing the service life of the equipment, and cannot maintain its performance in a vibrating or impact environment.
