摘要： A direct-action-type electrically-operated valve comprises a valve base provided with a valve cavity, a motor disposed on the upper end the valve base, and a screw rod. The screw rod is fitted and connected to a nut by means of threads. The nut is connected to a spool. Axial positions of a rotor of the motor and the valve base are relatively fixed. The upper end of the screw rod is fixedly connected to the rotor. Driven by the nut, the spool moves along the axial direction of the valve cavity to open or close a valve opening disposed on the valve base. The spool is a tubular structure provided with a balancing channel, and a seal piece for dividing the valve cavity into two independent cavities is disposed on the periphery of the spool.

摘要： A direct-action-type electrically-operated valve comprises a valve base (30) provided with a valve cavity, a motor (10) disposed on the upper end the valve base, and a screw rod (312). The screw rod (312) is fitted and connected to a nut (41) by means of threads. The nut is connected to a spool (42). Axial positions of a rotor (12) of the motor and the valve base are relatively fixed. The upper end of the screw rod is fixedly connected to the rotor. Driven by the nut, the spool moves along the axial direction of the valve cavity to open or close a valve opening (30a) disposed on the valve base. The spool is a tubular structure provided with a balancing channel, and a seal piece for dividing the valve cavity into two independent cavities is disposed on the periphery of the spool. A gear system is removed from the electrically-operated valve, so that unnecessary rotations are reduced, friction loss is reduced, and a response is direct, reliable and sensitive; the axial positions of the rotor and the valve base are relatively fixed, that is, the relative fixation of the rotor and a coil element during the working enables driving force to be stable; and obviously, for valve openings with a same size, the size of the motor using the valve opening is smaller than that in the background technology, which can meet requirements of miniaturization and large capacity.

摘要： Disclosed in the present invention is a flow regulating valve comprises a valve seat (1) and a casing (2). A motor (21) provided inside the casing (2) is connected to a screw rod (3) through the output shaft of the motor. The screw rod is connected to a screw nut (4) connecting with a valve rod (5) and the inner part of the valve rod (5) is provided with a mounting groove (51). The screw nut (4) is in clearance fit with the mounting groove (51) along the radical direction, and the inner wall of the mounting groove (51) is provided with an annular limiting groove (52). A limiting element (53) provided in the annular limiting groove (52) limits the position along the axial direction of the screw nut (4) and is in clearance fit with the outside of the screw nut. On one hand, the configuration design of the flow regulating valve is able to eliminate the coaxial degree error between the screw rod and the screw nut generated during the processing and assembling of components and parts, on the other hand, it is able to improve the reliability of the axial limitation of the screw nut.
