Description
Technical field
The utility model relates to a kind of valve.More particularly, incorporate wisdom valve is controlled in the throttling that the present invention relates to a kind of integrated energy perceptional function.
Background technique
50%～65% is consumed in central air-conditioning system in the annual power consumption of top-grade building thing, and unsteady flow amount air-conditioning system is compared with the flow setting type air-conditioning system, and water pump and cooling tower equipment on average can save energy 60%～80%, refrigeration host computer can save energy 10%～40%.But ubiquity the hydraulic misadjustment phenomenon in the air-conditioning flow-changing water system, and the pipe network water force unbalance causes a large amount of wastes of system's energy and the increase of establishing running noises easily.On energy meter, have very big difficulty simultaneously, the form charge of area is directly adopted in some areas, causes the energy-conservation idea of people thin, and the energy is wasted in a large number.At present society generally adopts is that dynamic balance valve accomplishes with the mode of energy meter combination that pipe network waterpower is controlled and the accumulative total of energy.
At present known principle and the method that is used for the cold and hot amount metering of central air-conditioner can be divided into three major types, i.e. simple cumulative method of time, wind side temperature difference flow accumulation method, water side temperature difference flow accumulation method.Wherein the energy meter theory of water side temperature difference flow accumulation method is perfect, and precision is high, and stable and reliable operation has a lot of mature technologies and the single product of seriation at present.Cold and heat meter based on this principle mainly is made up of flow transducer, pairing temperature sensor and integrator (controller) three parts.Press the difference of flow transducer form, this type energy meter also is divided into mechanical impeller type, ultrasonic type and three kinds of models of electromagnetic type.Wherein mechanical impeller type power meter scale is because of having miniature movable member in the mechanical structure, to having relatively high expectations of aqueous medium, requires the ancillary filter device in case the damage of impurity his-and-hers watches installing.The mechanical energy table is because of its principle of measurement and simple in structure, and is cheap, and precision is general, widely applied among the metering of fan coil unit at present.And the small-bore energy meter of ultrasonic type and electromagnetic type seldom has popularization and application because of the influence of factors such as price, technology.
With FlowCon, DANFOSS is the world-renowned brand transient equiliblium type electric control valve product (comprising the non-integral dynamic balance motor-driven modulating valve that common electric modulating valve and mechanical type pressure reduction/flow equilibrium control valve combines) of representative; It is a kind of electric control valve (or claim electronic dynamic adjustments valve or claim pressure independent type electric control valve) with mechanical self-powering type pressure reduction/flow automatic balance control function in essence; The Der Grundsatz der Maschinen of its dynamic differential pressure balance is very simple, promptly works as the two ends pressure reduction DP=P of one-piece type dynamic balance motor-driven modulating valve or non-one-piece type dynamic balance motor-driven modulating valve

3Automatic constant (pressure reduction control front-located mode principle).
The dynamic balance motor-driven modulating valve product of widely applying at present generally adopts the realization principle of spring mechanical self-powering type; Thereby having that through-current capability is obviously less than normal, transient equiliblium pressure reduction control range is little, application is dumb, the operating pressure differential initial value is higher, higher (because DP=DP totally consumes energy
1+ DP
2, the pressure that must sacrifice differential pressure controller during actual the use is kept the pressure reduction automatic constant of motorized adjustment part.The pressure of obviously sacrificing differential pressure controller also is the waste energy consumption).
