ZZYP self operated steam pressure regulating valve is a control valve that does not require external energy, uses the energy of the controlled medium itself as a power source, controls the position of the valve core through the actuator, changes the pressure difference and flow rate at both ends, and achieves automatic pressure regulation. This type of valve has comprehensive functions of measurement, execution, and control, and can work in environments without gas or electricity. It is widely used for pressure reduction and stabilization control of gas, liquid, and steam media in industries such as petroleum, chemical, power plants, light industry, printing and dyeing.
Structure and Working Principle
ZZYP self operated steam pressure regulating valve is mainly composed of stainless steel structure or cast iron material valve body, valve seat, valve core, balance spring and other components. Its working principle is to drive the valve core through the pressure change of the medium itself, achieving automatic adjustment. When the pressure behind the valve increases, the force acting on the diaphragm increases, compressing the spring and driving the valve core, reducing the valve opening until the pressure behind the valve drops to the set value; On the contrary, if the pressure behind the valve decreases, the valve opening degree increases until the pressure behind the valve rises to the set value.
Advantage
ZZYP self operated steam pressure regulating valve has demonstrated excellent performance in practical applications, especially under harsh working conditions of high temperature, high pressure, and high pressure difference. Through precise software calculation and sleeve multi-stage throttling pressure reduction technology, it effectively solves problems such as air cavitation, flash evaporation, blocked flow, vibration, and high noise. In addition, the advantages of this valve include no need for external energy, high adjustment accuracy, continuous pressure setting value, and flexible pressure adjustment after the valve.
In summary, ZZYP self operated steam pressure regulating valves plays an important role in many industrial fields with its unique advantages, especially in the absence of external energy supply. Its flange structure can be used in conjunction with various flange gate valve, flange butterfly valve, and flange ball valve.
