The invention relates to the field of shielding electric adjusting valves, in particular to a high-pressure and ultra-high-pressure shielding electric adjusting valve. The valve is composed of a valvebody, a
reducer, a valve core
assembly, a motor housing, a motor
stator, a motor leading wire
assembly, a shielding sleeve, a motor rotor, a valve body side bearing
assembly, a rear cover, a rear cover side
rotary converter, a bearing assembly, a rotary converted, a secondary shielding sleeve, a rotary converted leading wire assembly and a pressure balancing diaphragm. The electric adjusting valve has the advantages that the defect of
motor efficiency reduction due to the increasing of the pressure of an adjusting medium and the thickening of the motor shielding sleeve which is also called protective sleeve of an existing shielding electric adjusting valve is overcome and the defects of the damage of the pressure balancing diaphragm and the shielding sleeve, the difficulty of motor statorleading wire installing connection and the like caused by unstable sealing of an existing matching component 'high-pressure and ultra-
high pressure medium environment shielding motor' and the expansion and retraction through heat and cold respectively of
inert liquid contained in the
stator are overcome, the sealing of the high-pressure and ultra-high-pressure shielding electric adjusting valve is allowed to be reliable, the shielding sleeve is not influenced by the expansion and retraction caused by heat and cold respectively of the
inert liquid, and the installing and maintaining are convenient.
