Abstract

The invention discloses an electrically operated valve. The valve comprises a valve body part, a valve seat part, a nut part, a rotor part and a valve element part, the nut part is fixedly connected with the valve body part, the rotor part can drive the valve element part to move in the axial direction of the valve body part, the nut part comprises a nut, the rotor part comprises a rotor and a lead screw, the nut is in threaded connection with the lead screw, the valve element part comprises a valve sleeve and a valve element, the valve sleeve is roughly cylindrical, the valve element is roughly in an axially-through cylindrical shape, the valve sleeve is movably connected with the lead screw, the lead screw can drive the valve sleeve to move axially, the valve sleeve is fixedly connected with the valve element, the valve element can abut against or be separated from a sealing part of the valve seat part, the nut comprises a guide hole section, at least part of the valve sleeve is located on the guide hole section, the valve sleeve is in clearance sliding fit with the guide hole section, and the valve element part of the electrically operated valve is simple in structure.

Description

technical field [0001] The invention relates to the technical field of fluid control, in particular to an electric valve. Background technique [0002] In the field of fluid control technology, such as refrigeration technology, the electric valve can be used to cut off or adjust the refrigerant or adjust the suction pressure of the compressor. Figure 8 Shown is a schematic structural view of an electric valve in the background technology; Figure 9 shown as Figure 8 An exploded view of the middle spool assembly. Such as Figure 8 and Figure 9 As shown, the electric valve includes a motor part 01 , a connecting part 02 , a valve core part 03 and a valve body part 04 . The spool component 03 includes a screw sleeve 031 , a spool body 032 , a valve head assembly 033 and a preload spring 034 , and the spool assembly includes a valve head connecting rod 0331 , a valve head 0332 , a sealing gasket 0333 and a thread retaining ring 0334 . The screw sleeve 031 is connected with...
