The structural representation regulating valve that Fig. 1 provides for the embodiment of the present invention.
Description of reference numerals:
11-valve body, 12-the first temperature sensor, 13-the second temperature sensor, 14-executor, 15-the first pressure transducer, 16-the second pressure transducer.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with accompanying drawing, the present invention is further detailed.
As shown in Figure 1, the embodiment of the present invention provides one to regulate valve, it includes valve body 11 and motorized adjustment part, the first temperature sensor 12 and the second temperature sensor 13, spool (not shown) that motorized adjustment part includes being installed in valve body 11 and for regulating the executor 14 of the aperture of spool, valve body 11 is installed on return pipe, it can adopt Nodular cast iron material to make, and spool can adopt bronze material to make, and regulates the sealing member in valve and adopts ethylene propylene diene rubber to make.
First temperature sensor 12 is arranged on inlet pipeline, and it is used for detecting inflow temperature; Second temperature sensor 13 is arranged on water return pipeline, and it is used for detecting return water temperature. Being installed on return pipe owing to regulating valve, therefore the second temperature sensor 13 can be directly mounted on valve body, detects return water temperature with this. First temperature sensor 12 and the second temperature sensor 13 all electrically connect with executor 14, have the control device for the aperture according to the difference control spool between inflow temperature and return water temperature in this executor 14.
Executor 14 is intelligent executor, its acceptable signal, and controls the aperture of spool accordingly, so that it is constant to enter backwater temperature difference, certainly, herein constant is not always same value, and is held in certain scope. Above-mentioned signal and aforementioned inflow temperature and return water temperature, executor can calculate difference between the two. On this executor 14 also can set-point type liquid crystal display device, show, with this, whole state parameters that valve is current, for instance temperature, flow, energy etc. Executor 14 can be local or inputted the setting value �� Tset entering backwater temperature difference to keep by host computer, the control chip of executor 14 can magnitude relationship between comparison setting value �� Tset and actual temperature approach �� T, then valve is carried out aperture control. For heating system, when �� T is less than �� Tset, it was shown that the aperture of spool is excessive, does not have abundant heat exchange in branch road, it should close minor valve; When �� T is more than �� Tset, it was shown that executor's aperture is too small, and in branch road, flow is very few, it should open big valve, the final goal of adjustment is �� T=�� Tset.
After using above-mentioned adjustment valve, inflow temperature that first temperature sensor 12 detects and the return water temperature that the second temperature sensor 13 detects all are transferred to executor 14, executor 14 is according to the difference between inflow temperature and return water temperature, control the aperture of spool, so that the difference between inflow temperature and return water temperature meets design requirement. Compared to the content introduced in background technology, above-mentioned adjustment valve can control to adjust the spool of valve in real time according to feedback temperature value, with the waterpower energy imbalance existed in this alleviation system better.
Additionally, what valve opening was adopted by above-mentioned executor 14 is PID control (i.e. proportional integral differential control), measure the actual value of controlled variable, compared with expected value, carry out the response of correcting system by this deviation, namely by the continuous comparison setting value of feedback closed loop and actual value, and guide next step adjustment, this adjustment is small and continuous print, does not have the acute variation of flow. So can extending the service life of valve and pipeline and lower noise, end does not have sometimes hot and sometimes cold phenomenon. Meanwhile, when using this adjustment valve, it is possible to when preliminary debugging, unification arranges a middle aperture (such as 50% aperture flow), after system is run, regulate valve according to each actual temperature approach, aperture to be automatically adjusted, be finally reached the state of each branch balance. Use middle system that fluctuation occurs, regulate valve also can carry out therewith adapting to regulate, so system can keep a comparatively ideal running status all the time, without artificial participation, management personnel have only to the operation of monitoring thermal source or low-temperature receiver, reduce the program of system debug with this.
For the ease of the setting of the second temperature sensor 13, also can offering thermometer hole on valve body 11, the second temperature sensor 13 is arranged in this thermometer hole. Compared to return pipe, valve body 11 offers thermometer hole, and the second temperature sensor 13 is installed in this thermometer hole is easier to operate to, reach object defined above with this.
Further, the adjustment valve that the embodiment of the present invention provides may also include the first pressure transducer 15 and the second pressure transducer 16, this the first pressure transducer 15 is arranged at the water inlet end of valve body 11, second pressure transducer 16 is arranged at the water side of valve body 11, and first pressure transducer 15 and the second pressure transducer 16 be typically mounted in the pressure port on valve body 11, both of which electrically connects with executor 14. Executor 14 can calculate the pressure reduction �� P before and after valve body according to the piezometer imported and exported, and in executor 14, pre-entered the flow parameter KV regulating valve, the aperture of back valve core is controlled according to current pressure reduction and executor, flow Q now can be calculated, whether meet the requirements with the operational factor that this confirms system. It addition, according to the detected value of the first pressure transducer 15 and the second pressure transducer 16, executor 14 can judge whether the pressure reduction at valve body 11 two ends is in zone of reasonableness, to ensure to regulate valve normal operation.
In a kind of embodiment, aforesaid first temperature sensor the 12, second temperature sensor the 13, first pressure transducer 15 and the second pressure transducer 16 are all connectable to the same position place on executor 14, but this kind of structure cannot clearly differentiate above-mentioned each sensor position on executor 14. Therefore, can offering the first connection jaws and the second connection jaws on executor 14, the first pressure transducer 15 is connected to the first connection jaws place, and the second pressure transducer 16 is connected to the second connection jaws place. In like manner, executor 14 can arranging the 3rd connection jaws and the 4th connection jaws, the first temperature sensor 12 is connected to the 3rd connection jaws place, and the second temperature sensor 13 is connected to the 4th connection jaws place.
After the executor 14 that the embodiment of the present invention provides is connected to host computer, host computer can access and obtain the data such as the temperature of system, flow, pressure, energy at any time, and host computer also can direct setup control temperature approach. According to data such as the temperature obtained, flow, pressure, it is possible to detect the running status of system easily, according to energy datum, it is possible to analyze the energy consumption of system, as the setting according to the system of improvement.
Preferably, executor 14 is installed on valve body 11, so that executor 14 is connected as a whole with valve body 11, it is simple to install and control the carrying out of operation, can shorten simultaneously and regulate the length of wire harness in valve.
Below some one exemplary embodiment of the present invention is only described by the mode of explanation, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, it is possible to by various different modes, described embodiment is modified. Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as the restriction to the claims in the present invention protection domain.
