Embodiment Construction

[0017] A multifunctional constant flow regulating valve for fluid regulation and automatic control, including a valve body 1, a valve cover 2 is installed on the valve body 1, a valve shaft 3a, a regulating valve disc 3b, a double-seat valve disc 5, and a valve body 1 are installed in the valve body 1. Cover 4, differential pressure sensor 6. The bonnet 2 presses the pressure flange 7 to adjust the valve disc 3b to achieve positioning. The bonnet 2 is connected to the valve body through the flange, and the bonnet is tightly fixed on the valve body through the ring-shaped sealing boss on the inner side of the lower part of the flange and the sealing ring. On the valve body, and ensure a good sealing effect. The valve shaft 3a can be rotated by different actuators to change the opening degree of the regulating disc to adjust the flow rate. There is a dial 14 on the valve cover 2 to display the flow value.

[0018] In this embodiment, the pressure difference sensor 6 is sealed a...

Abstract

The invention relates to a multi-functional constant flow control valve used for flow adjustment and automatic control. The multi-functional constant flow control valve includes a valve body which is provided with a valve cover at the upper portion and a sewage draining exit at the lower portion. The valve cover is provided with a valve shaft at the center. The valve shaft is provided with an adjusting valve clack at the lower portion. A valve pocket, a differential pressure receptor and a bi-seat valve clack with a function of compensating the differential pressure are arranged inside the valve body. The valve pocket, the differential pressure receptor and the bi-seat valve clack with the function of compensating the differential pressure constitute a valve core. Compared with the prior art, the multi-functional constant flow control valve is more reasonable and compact in structure, simple in disassemble and maintenance, visual in flow display, and abundant in function, thus being applicable to more fields.
