Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the illustrated embodiments are provided for illustration only and are not intended to limit the scope of the present utility model.

As shown in fig. 1 and 2, the supporting device of the screw gland of the electric actuator of the present embodiment is used for a regulating valve of a deaerator and is arranged between the screw gland 2 of the electric actuator 1 and the valve body 3.

The supporting device comprises four supporting pieces 5 which are arranged in an array along the circumferential direction of the screw gland 2, each supporting piece 5 comprises a supporting main body 6, an adjusting bolt 7, a fixing nut 8 and a fastening nut 9, the fixing nuts 8 are fixedly connected to the end parts of the supporting main bodies 6 through welding, holes for the adjusting bolts 7 to pass through are formed in the supporting main bodies 6 along the axial direction of the supporting main bodies, and the supporting main bodies 6 in the embodiment specifically adopt a steel pipe structure;

a part of the adjusting bolt 7 is inserted into the supporting body 6 through the end part of the supporting body 6 and is in threaded connection with the fixing nut 8, the adjusting bolt 7 of the embodiment is arranged at one end of the supporting body 6, and the adjusting bolt 7 is not arranged at the other end of the supporting body 6;

the fastening nut 9 is sleeved on the adjusting bolt 7 and is positioned on the outer side of the supporting body 6, the fastening nut 9 is in threaded connection with the adjusting bolt 7, one end of the supporting piece 5 is abutted against the outer end face of the screw gland 2 of the electric actuator 1, and the other end of the supporting piece is abutted against the valve cover 4 of the valve body 3.

When the screw nut pressing device is used, four supporting pieces are arranged between the screw nut pressing cover 2 and the valve body 3 of the electric actuator 1, the bottom end of the main body 6 is specifically supported and placed on the valve cover 4, the other end, namely the adjusting bolt 7, faces the electric actuator 1, the adjusting bolt 7 is rotated to enable the adjusting bolt 7 to move upwards to the bottom end face of the screw nut pressing cover 2 along the drawing, the screw nut pressing cover 2 is kept at a working position, then the fastening nut 9 is rotated to enable the fastening nut to descend to abut against the upper end face of the fixing nut 8 for fastening, and installation is completed.
