Imported steam self-operated pressure regulating valve
Purpose and scope of application of imported steam self-operated pressure regulating valve
The imported steam self-operated pressure regulating valve (hereinafter referred to as the pressure valve) is an energy-saving product that does not require external energy and only relies on the pressure change of the regulating medium to automatically regulate the pressure. It has comprehensive functions of measurement, execution and control. It is widely used in petroleum, chemical, metallurgy, light industry and other industrial sectors and urban heating and ai systems. This product can be used as a pressure control device for non-corrosive (*temperature 350℃) liquid, gas, steam and other media.
Structure and working principle of imported steam self-operated pressure regulating valve
This product is a direct acting self-operated pressure regulating valve. It is composed of valve body, valve seat, valve core parts, valve cover, top plate, upper and lower diaphragm covers, diaphragm, spring, adjusting nut and other parts.
working principle
(I) Working principle of pressure adjustment after valve: (see figure la)
The pressure Pl of the process medium before the valve is changed to the pressure P2 after the valve after the valve core and valve seat are throttled. P2 enters the lower membrane chamber of the actuator through the control line to act on the top plate. The force generated is balanced with the reaction force of the spring. Determine the relative position of the valve core and valve seat. Control the pressure after the valve. When the pressure P2 after the valve increases. The force of P2 acting on the top plate also increases. at this time. The force of the top plate is greater than the reaction force of the spring. Make the valve core close to the position of the valve seat. Until the force of the top plate is balanced with the reaction force of the spring. At this time. The flow area between the valve core and the valve seat is reduced. The flow resistance becomes larger. Thereby reducing P2 to the set value. Similarly, when the pressure P2 after the valve decreases. The direction of action is opposite to the above. This is the working principle of pressure adjustment after the valve. When it is necessary to change the set value of the pressure P2 after the valve. Adjustable adjusting nut 8.
