Imported Self-Regulating Valve

The self-regulating valve imported consists of components such as the valve body, seat, and core. It utilizes the energy of the medium itself to drive the actuator, which in turn drives the valve to regulate parameters such as temperature, pressure, flow, and liquid level. Depending on the object of regulation, it can be categorized into self-regulating pressure valves, low-pressure regulating valves, pressure relief valves, temperature regulating valves, flow regulating valves, and differential pressure regulating valves. They are widely used in the automatic control systems of various equipment in the oil, chemical, power station, light industry, and dyeing and printing industries for reducing pressure, stabilizing pressure (used for post-valve pressure regulation), pressure relief, and stabilizing pressure (used for pre-valve pressure regulation) of gases, liquids, and steam mediums.

Features:

Energy-saving and environmentally friendly, it can achieve automatic control without external energy input, benefiting companies in cost reduction. With the ever-tightening energy situation today, it is sure to have an increasingly broader application prospect.

Note:1The closed-type is used for pressure regulation after the valve, closing the valve when the pressure after the valve increases to achieve the purpose of pressure reduction and stabilization.

2The pressure relief type is used for post-valve pressure regulation. When the post-valve pressure increases, the valve opens to achieve the purpose of pressure relief and stabilization.

Self-contained pressure regulating valve operating principle:

The pressure-reducing valve used to control the pressure after the valve operates in a closed type. Its principle is as follows: the medium flows into the valve body in the direction of the arrow, passes through the valve core and seat to throttle, and then exits. Another path, after being cooled by the condenser (used when the medium is steam), is introduced into the actuator and acts on the diaphragm, causing the valve core to move correspondingly, achieving the purpose of pressure reduction and stabilization. If the pressure after the valve increases, the force acting on the diaphragm increases, compressing the spring, which drives the valve core, reducing the valve opening until the pressure after the valve drops to the set value. Similarly, if the pressure after the valve decreases, the force acting on the diaphragm decreases, and the counterforce of the spring drives the valve core, increasing the valve opening until the pressure after the valve rises to the set value.
