Imported self valve self operated pressure regulating valve inlet pressure regulating valve self pressure regulating valve according to the pressure point position valve before and after the two class, check valve before the pressure point when used to adjust the valve before the pressure constant; check valve after the pressure point when, for constant pressure regulating valve.
Imported self valve self operated pressure regulating valve inlet pressure regulating valve when the pressure valve before and after introducing the actuator on both sides of the chamber, self pressure regulating valve can adjust the pressure regulating valve at both ends of the constant, can also be installed in the pipe orifice at both ends of the pressure into thin film on both sides of the air chamber mechanism implementation.
To form a self operated flow control valve, or in any other way will achieve flow control flow detection with self operated differential pressure regulating valve.
Self pressure regulating valve is divided into self pressure, differential pressure and flow control valve three series.
LIT self regulating valve function
Imported self valve self operated pressure regulating valve inlet pressure regulating valve is the valve output feedback signal (pressure, pressure, temperature) through the signal tube opening is transferred to the actuator valve to change the valve, to adjust the pressure, flow rate, temperature of the.
The advantages of self regulating valve.
Imported self valve self operated pressure regulating valve inlet pressure regulating valve is a new type of self regulating valve. Compared with the manual control valve, and its advantage is to automatically adjust;
Compared with the electric control valve, it has the advantages of no need of external power. The practice proved that in the closed water circulation system (such as hot water heating system, chilled water system), the correct use of the valve, can easily achieve the flow distribution system; dynamic balance can be realized; can greatly simplify the debugging of the system can be stable; the pump's working condition etc..
The classification of self regulating valve
Imported self valve self operated pressure regulating valve inlet pressure regulating valve is divided into direct and indirect effect acting two.
1) direct acting valve
Direct acting valve is also called the spring loaded valve, its structure and elastic components, such as springs, bellows, bellows type bulb, using elastic force and the principle of balance between the feedback signal.
2) indirect acting valve
Indirect acting valve, added a pilot (pilot valve) which plays a role in the amplification of feedback signal and then through the implementing agencies, driving the main valve valve valve movement to achieve the purpose of changing the valve opening.
If the pressure regulating valve, the feedback signal is the valve outlet pressure, through the introduction of signal control actuator.
If the flow control valve, there is a hole in the valve outlet (or other resistance devices) differential pressure signal into the actuator from the orifice ends out.
If the temperature control valve, valve outlet there is a temperature sensor (or Wen Bao) through the medium temperature sensor in thermal actuator.
