Abstract
The invention provides a high-accuracy temperature control valve. The high-accuracy temperature control valve comprises a valve body, an electric actuator and a temperature sensing probe, wherein the electric actuator is arranged on the valve body; a drive motor is arranged in the electric actuator; a connection rod is arranged between the electric actuator and the valve body. The high-accuracy temperature control valve is characterized in that a temperature processor is arranged on one side of the drive motor, a data processor is arranged at the top of the temperature sensing probe and connected with the temperature processor though a wire, and the connection rod is a bidirectional rotary connection rod. The temperature processor receives the temperature detection signal transmitted by the temperature sensing probe in real time and processes the signal, then the purpose of controlling the valve to be switched on or off is achieved through the drive motor, control is easy, reaction is sensitive, and the problem that equipment cannot be used due to failure of temperature sensing materials is avoided. The bidirectional rotary connection rod can drive a valve element to rotate in dual directions, the valve element is prevented from being jammed by foreign matter, and the anti-jamming function is achieved. The high-accuracy temperature control valve is novel in design, simple in structure and suitable for being applied and popularized in industrial production.
Description
Technical field
The invention belongs to valve technology field, particularly relate to a kind of high precision temperature control valve.
Background technique
Electric temperature control valve is the typical apply of electric flow control valve in domain of control temperature, basic principle is by controlling heat exchanger, air-conditioner set or other inlet flow rates with primary fluid or refrigerant in heat, cool equipment, to reach the object controlling liquid outlet temperature.Electric temperature control valve is a kind of control gear adopting Der Grundsatz der Maschinen, a kind ofly integrate induction mechanism, actuator, feedback mechanism, the new-type temperature of definite value mechanism, flow control valve, it changes traditional thermal control process temperature, the controlling method of flow, avoid in thermal control process, thermal technology is spattered a little more, the feature that maintenance is more.In electric temperature control valve, important parts are heat responsive elements, China starts the thermostat valve of self design with heat responsive element in the eighties in last century, up to the present, existing high volume applications is in Practical Project, but also often there is the problems such as valve seal is bad, and heat responsive element is malfunctioning in these thermostat valves.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of control sensitive, airtight performance is excellent, the simple high precision temperature control valve of structure.
The present invention for the taked technological scheme that achieves the above object is:
A kind of high precision temperature control valve, comprise valve body, electric actuator and temperature inductance probe, described electric actuator is arranged on valve body, drive motor is provided with in electric actuator, connecting rod is provided with between electric actuator and valve body, it is characterized in that described drive motor side is provided with Temperature processor, Temperature processor comprises temperature indicator and temperature adjustment buttons, described temperature inductance probe top is provided with data processing system, described data processing system is connected with Temperature processor by wire, and described connecting rod is Double-directional rotary connecting rod.
Described temperature inductance probe quantity is 2.
Described temperature indicator is liquid crystal display.
Beneficial effect of the present invention is: the setting of Temperature processor can be gone forward side by side row relax by the temperature detection signal that transmitted by temperature inductance probe of real-time reception, and then regulate running and the closedown of drive motor, reach the object that control valve opens and closes, control simple, be quick on the draw, avoid the problem that the equipment caused because temperature sensing material is malfunctioning cannot use; And be provided with temperature indicator and can observe internal fluid temperature at any time, be beneficial to manufacture control; Double-directional rotary connecting rod can carry out band movable valve plug bidirectional rotation, prevents spool stuck by foreign matter, has anti-jamming function.The present invention is novel in design, structure is simple, is suitable for applying in industrial production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-valve body, 2-electric actuator, 3-temperature inductance probe, 4-drive motor, 5-connecting rod, 6-Temperature processor, 7-temperature indicator, 8-temperature adjustment buttons, 9-data processing system, 10-wire.
Embodiment
For understanding content of the present invention, Characteristic further, hereby exemplifying following examples and being described with reference to the accompanying drawings as follows:
A kind of electric temperature control valve, comprise valve body 1, electric actuator 2 and temperature inductance probe 3, electric actuator 2 is arranged on valve body 1, be provided with drive motor 4 in electric actuator 2, be provided with connecting rod 5 between electric actuator 2 and valve body 1, drive motor 4 side is provided with Temperature processor 6, Temperature processor 6 comprises temperature indicator 7 and temperature adjustment buttons 8, temperature inductance probe 3 top is provided with data processing system 9, and data processing system 9 is connected with Temperature processor 6 by wire 10, and connecting rod 5 is Double-directional rotary connecting rod.
Working procedure of the present invention is: temperature inductance probe 3 is placed in pipeline fluid test fluid inside temperature, and collect the temperature signal that detects by top data processing system 9 and transfer on Temperature processor 6 and show, the signal that simultaneous temperature processor 6 Intelligent treatment detects, and transfer instruction is to drive motor 4, when fluid temperature (F.T.) exceedes setting temperature, drive motor 4 operates and drives valve closing to cut off heating agent, thus reduces fluid temperature (F.T.); When fluid temperature (F.T.) is lower than setting temperature, Temperature processor 6 indicates drive motor 4 to operate and opens large valve, strengthens flow rate of heat medium thus, fluid temperature (F.T.) is raised.
Above the specific embodiment of the present invention has been described in detail, but described content being only better embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
