Specific embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with
Accompanying drawing is further detailed to the utility model.
As shown in figure 1, the utility model embodiment provides a kind of balanced valve, the balanced valve include valve body 11,
Dynamic equilibrium portion (not shown), the first temperature sensor 12, second temperature sensor 13 and hold
Row device 14, valve body 11 is generally mounted on water return pipeline, and it can be made using cast iron quality.
Dynamic equilibrium portion is installed on the inside of valve body 11, and it can keep default stream under default aperture
Amount.Dynamic equilibrium portion is capable of achieving two functions：Flow equilibrium and Flow-rate adjustment.Flow equilibrium exists
In the range of its operting differential pressure, flow constant；Flow-rate adjustment is flow control function, an aperture
One constant and unique flow of correspondence.Flow equilibrium function is by the spring reality in dynamic equilibrium portion
When adjusting spool area of passage, realized with balancing impact that pressure reduction brings.Flow regulating function is logical
Valve rod action is crossed, drives internal restriction component controls excessively stream open area to realize.
First temperature sensor 12 is arranged on inlet pipeline, and it is used to detect inflow temperature；Second is warm
Degree sensor 13 is arranged on water return pipeline, and it is used to detect return water temperature.Because balanced valve is installed on
On return pipe, therefore second temperature sensor 13 can be directly mounted on return pipe, and with this backwater temperature is detected
Degree.
Actuator 14 is intelligent actuator, its acceptable signal, and control dynamic equilibrium portion accordingly
Aperture so that balanced valve to enter backwater temperature difference constant, certainly, herein constant is not always same
One value, and be held in certain scope.Above-mentioned signal is aforementioned inflow temperature and return water temperature,
Actuator can calculate difference between the two.Dot lcd can also be arranged on the actuator 14 to show
Show device, the current whole state parameters of valve, such as temperature, flow, energy etc. are shown with this.Hold
Row device 14 can be input into the setting value for entering backwater temperature difference to be kept locally or by host computer, perform
The control chip of device 14 can compare the magnitude relationship between setting value and actual temperature approach, then to valve
Carry out aperture control.Usually, if actual temperature approach is less than setting value, illustrate that flow rate of pipelines is excessive,
End heat exchange is insufficient, and actuator can send pass valve events signal, reduce flow；If the actual temperature difference
Value is more than setting value, illustrates that flow rate of pipelines is too small, underfed, and actuator can send valve opening action letter
Number.
When being embodied as, the corresponding flow value ginseng of aperture of valve has been input on the control chip of actuator 14
Number, i.e., according to current aperture, actuator 14 draws the flow value Q of pipeline.According to the flow Q of pipeline,
With the temperature approach △ T for entering backwater, actuator can calculate the energy value E of branch road output according to following formula
(heat or cold)：

The temperature approach of backwater, that is, the first temperature sensor 12 and second temperature sensor 13 surveyed between numerical value
Difference.
After above-mentioned balanced valve, the inflow temperature and second temperature that the first temperature sensor 12 is detected is passed
The return water temperature that sensor 13 is detected is transferred to actuator 14, and actuator 14 is according to inflow temperature and returns
Difference between coolant-temperature gage, controls the aperture of dynamic equilibrium portion, so that between inflow temperature and return water temperature
Difference meet design requirement.Compared to the content described in background technology, above-mentioned balanced valve being capable of basis
Feedback temperature value controls in real time the dynamic equilibrium portion of balanced valve, so that the temperature of system reaches constant shape
State.
In addition, above-mentioned actuator 14 uses PID control (i.e. proportional-integral-differential control to valve opening
System), the actual value of controlled variable is measured, compared with desired value, with this deviation come the sound of correcting system
Should, i.e., setting value and actual value are constantly compared by feedback closed loop, the adjustment of next step is and guided, the adjustment
It is small and continuous, is not in the acute variation of flow.The use of valve and pipeline can so be extended
Life-span, and lower noise, end is not in sometimes hot and sometimes cold phenomenon.Simultaneously as dynamic in valve body
State balance portion causes valve to have constant flow under an aperture, so other pipelines are carried out in system
Aperture adjustment can't produce impact to the flow of this branch road, so also just reduce the action frequency of valve
Rate, reduces noise and extends the service life of valve with this.
For the ease of the setting of second temperature sensor 13, thermometer hole can be also opened up on valve body 11, the
Two temperature sensors 13 are arranged in the thermometer hole.Compared to return pipe, on valve body 11 thermometric is opened up
Hole, and second temperature sensor 13 is installed in the thermometer hole is easier to operate to, aforementioned mesh is reached with this
's.
Further, the balanced valve that the utility model embodiment is provided may also include first pressure sensor 15
