[0002] The pressure regulating valve is a kind of regulating the flow of the medium by controlling the opening degree of the internal opening and closing parts, and reducing the pressure of the medium by adjusting the flow rate, and at the same time adjusting the opening degree of the opening and closing parts with the help of the pressure behind the valve to make the pressure after the valve Keep within a certain range, in the case of constant changes in the inlet pressure, keep the outlet pressure fluctuating in a small range of valves, usually need to install a pressure regulating valve in the pipeline to release the pressure to protect the pipeline and equipment from bein

Abstract

The invention provides a segmented valve. The segmented valve comprises a valve head, a valve body and a valve tail; the valve head, the valve body and the valve tail are connected in sequence; and flange structures matched with pipes are arranged at free ends of the valve head and the valve tail. The segmented valve further comprises a pressure adjusting valve electric actuator, a push rod, a valve rod, a valve element, inner and outer porous sleeves, a reverse flowing hole and a sealing ring; a fluid enters the interior of a valve body runner from an inlet, passes through a double-sleeve porous structure, and flows out from an outlet; the pressure adjusting valve electric actuator drives the push rod; the push rod drives the valve rod; the valve rod is connected with the valve element; and no gap is formed between the valve element and an inner sleeve. The segmented valve can effectively balance the valve rod, the push rod and external pressure to prevent the defects of force waste and even deformation of structural parts in the adjusting process, and meanwhile, is easy to manufacture a three-section structure, simple in assembly and low in cost.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a segmented valve. Background technique [0002] The pressure regulating valve is a kind of regulating the flow of the medium by controlling the opening degree of the internal opening and closing parts, and reducing the pressure of the medium by adjusting the flow rate, and at the same time adjusting the opening degree of the opening and closing parts with the help of the pressure behind the valve to make the pressure after the valve Keep within a certain range, in the case of constant changes in the inlet pressure, keep the outlet pressure fluctuating in a small range of valves, usually need to install a pressure regulating valve in the pipeline to release the pressure to protect the pipeline and equipment from being damaged by high pressure, Pressure regulating valves are widely used in high-rise buildings, areas where the water pressure of urban water supply pipe ne...
