Detailed Description
The movable flange electric regulating valve shown in fig. 1 comprises a valve body 1, a valve seat 2, a valve clack 5, a valve cover 6, a valve rod 7 and an actuator 10, wherein the valve clack 5 is installed at the lower end of the valve rod 7, the upper end of the valve rod 7 is connected with the actuator 10, the actuator 10 adopts an electric actuator, and the inlet and outlet channels of the valve body 1 are respectively provided with a flange; the flange is characterized in that the flange is a movable flange, the movable flange is composed of a flange plate 4 and a fixed plate 3, the fixed plate 3 is hermetically arranged at two ends of an inlet and outlet channel of a valve body 1, the diameter of the fixed plate 3 is larger than the outer diameter of the inlet and outlet channel of the valve body 1, the fixed plate 3 is connected with the valve body 1 through welding or threads, the center hole of the flange plate 4 is in clearance fit with the outer circular surface of the inlet and outlet channel of the valve body 1, a circular hole which is in movable fit with the outer circular surface of the fixed plate 3 is formed in a radial plane of the flange plate 4 which is positioned on one side of. When the valve is installed, the pipeline flange can be installed by aligning the rotary flange plate 4 with the pipeline flange under the condition that the valve body is not moved.
And a sealing gasket is arranged between the bottom surface of the circular hole of the flange plate 4 and the radial contact surface of the fixed disk 3, so that the sealing between the flange plate 4 and the fixed disk 3 is realized.
And a sealing ring is arranged between the outer circular surface of the fixed disk 3 and the inner hole wall of the circular hole of the flange plate 4, so that the sealing between the flange plate 4 and the fixed disk 3 is realized.
The actuator 10 is arranged on the valve cover 6 through the extension bar 9, and the radiator 8 is arranged on the outer circular surface of the extension bar 9, so that the influence of the medium temperature on the actuator 10 is reduced.
