Specific embodiment
In order to which those skilled in the art is made to more fully understand technical scheme of the present invention, below in conjunction with attached drawing to this hair
It is bright to be further detailed.
As shown in Figure 1, the embodiment of the present invention provides a kind of balanced valve, which includes valve body 11, dynamic equilibrium portion
(not shown), the first temperature sensor 12, second temperature sensor 13 and actuator 14, valve body 11 are generally mounted to return water
On pipeline, cast iron quality can be used and be made.
Dynamic equilibrium portion is installed on the inside of valve body 11, can keep preset flow under default aperture.Dynamic is flat
Two functions can be achieved in weighing apparatus part：Flow equilibrium and flow-rate adjustment.I.e. in the range of its operting differential pressure, flow is kept flow equilibrium
It is constant；Flow-rate adjustment, that is, flow control function, an aperture correspond to a constant and unique flow.Flow equilibrium function passes through
The real-time adjusting spool area of passage of spring in dynamic equilibrium portion is realized with the influence that balance pressure difference band comes.Flow-rate adjustment
Function is acted by valve rod, and internal restriction component controls overcurrent open area is driven to realize.
First temperature sensor 12 is set on inlet pipeline, is used to detect inflow temperature；Second temperature sensor 13
It is set on water return pipeline, is used to detect return water temperature.Since balanced valve is installed on return pipe, second temperature sensing
Device 13 can be directly mounted on return pipe, and return water temperature is detected with this.
Actuator 14 be intelligent actuator, acceptable signal, and accordingly control dynamic equilibrium portion aperture so that
Balanced valve it is constant into backwater temperature difference, certainly, herein constant is always not same value, and is held in certain range
It is interior.Above-mentioned signal, that is, aforementioned inflow temperature and return water temperature, actuator can calculate difference between the two.The actuator 14
On dot matrix lcd can be also set, the current whole state parameters of valve, such as temperature, flow, energy are shown with this
Deng.Actuator 14 can input the setting value into backwater temperature difference to be kept, the control of actuator 14 locally or by host computer
Coremaking sector-meeting compares the magnitude relationship between setting value and practical temperature difference, then carries out aperture control to valve.Usually, such as
Fruit border temperature difference is less than setting value, illustrates that flow rate of pipelines is excessive, and end heat exchange is insufficient, and actuator, which can be sent out, closes valve events letter
Number, reduce flow；If practical temperature difference is more than setting value, illustrate that flow rate of pipelines is too small, underfed, actuator can send out and hold
Valve events signal.
When it is implemented, the corresponding flow value parameter of aperture of valve, i.e. root are inputted on the control chip of actuator 14
According to current aperture, actuator 14 obtains the flow value Q of pipeline.According to the flow Q of the pipeline and temperature difference △ T into return water, hold
Row device can calculate the energy value E (heat or cold) of branch output according to following formula：
Wherein：C is fluid specific heat, and ρ is fluid density, and t is the unit time, and Q is flow, and △ T are the temperature difference into return water,
Namely the first temperature sensor 12 and second temperature sensor 13 survey the difference between numerical value.
After above-mentioned balanced valve, inflow temperature and second temperature sensor 13 that the first temperature sensor 12 detects are examined
The return water temperature measured is transferred to actuator 14, and actuator 14 is according to the difference between inflow temperature and return water temperature, control
The aperture of dynamic equilibrium portion, so that the difference between inflow temperature and return water temperature meets design requirement.Compared to background skill
Content described in art, above-mentioned balanced valve can control the dynamic equilibrium portion of balanced valve in real time according to feedback temperature value,
So that the temperature of system reaches steady state.
In addition, above-mentioned actuator 14 to valve opening using PID control (i.e. proportional integral differential control), measure
The actual value of controlled variable, it is with this deviation come the response of correcting system, i.e., continuous by feedback closed loop compared with desired value
Setting value and actual value are compared, and guides the adjustment of next step, which is small and continuous, is not in the violent of flow
Variation.The service life of valve and pipeline, and lower noise can be extended in this way, end is not in sometimes hot and sometimes cold shows
As.Simultaneously as the dynamic equilibrium portion in valve body causes valve to have constant flow under an aperture, so in system
The aperture adjustment that other pipelines carry out can't have an impact the flow of this branch, also just reduce the action frequency of valve in this way
Rate, with the service life that this reduces noise and extends valve.
For the ease of the setting of second temperature sensor 13, thermometer hole, second temperature sensing can be also opened up on valve body 11
Device 13 is set in the thermometer hole.Compared to return pipe, thermometer hole is opened up on valve body 11, and second temperature sensor 13 is pacified
Loaded on being easier to operate in the thermometer hole, foregoing purpose is reached with this.
Further, balanced valve provided in an embodiment of the present invention may also include first pressure sensor 15 and second pressure passes

In the water outlet of valve body 11, and first pressure sensor 15 and second pressure sensor 16 are electrically connected with actuator 14.When
When one pressure sensor 15 is set to the water inlet end of valve body 11, it is by first pressure sensor 15 and second pressure sensor 16
Pressure difference between 11 two-port of detectable valve body, actuator 14 can judge the pressure difference whether in zone of reasonableness accordingly, to protect
Demonstrate,prove balanced valve normal work.When first pressure sensor 15 is set on water inlet pipe, you can detection inlet pipeline and return pipe
Pressure difference between road, to ensure the normal operation of system.
Aforementioned the first temperature sensor 12, second temperature sensor 13, first pressure sensor 15 and second pressure passes
Sensor 16 can individual leads be connected on actuator 14, but to make harness compacter, first can be set on actuator 14
Connection jaws, first pressure sensor 15 and second pressure sensor 16 are all connected at the first connection jaws.Similarly, on actuator
Second connection jaws can be set, and the first temperature sensor 12 and second temperature sensor 13 are all connected at second connection jaws.Separately
Outside, actuator 14 has power supply and control inlet interface.
After actuator 14 provided in an embodiment of the present invention is connected to host computer, host computer can access and obtain system at any time
The data such as temperature, flow, pressure, energy, host computer also can directly set control temperature difference.According to obtained temperature, flow, pressure
The data such as power, can easily detecting system operating status, according to energy datum, can with the energy consumption of analysis system, with
This is the setting according to the system of improvement.
Preferably, actuator 14 is installed on valve body 11, so that actuator 14 is connected as an entirety with valve body 11, is convenient for
Installation and the progress of control operation, while the length of harness in balanced valve can be shortened.
