High-accuracy temperature control valve

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 [0001] The invention belongs to the technical field of valves, in particular to a high-precision temperature control valve. Background technique [0002] The electric temperature control valve is a typical application of the electric flow regulating valve in the field of temperature control. The basic principle is to control the liquid outlet by controlling the inlet flow of the primary heat medium or refrigerant in the heat exchanger, air conditioning unit or other heat and cold equipment. temperature purpose. The electric temperature control valve is a control device that adopts mechanical principles. It is a new type of temperature and flow control valve that integrates induction mechanism, actuator, feedback mechanism and fixed value mechanism. It changes the traditional thermal control temperature, The flow control method avoids the characteristics of more thermal splash points and more maintenance in thermal control. An important part of the elect...

Problems solved by technology

An important part of the electric temperature control valve is the temperature sensing element. my country began to design and manufacture temperature control valves with temperature sensing elements in the 1980s. So far, a large number of them have been used in practical projects, but these temperature In the control valve, there are often problems such as poor sealing of the valve and failure of the temperature sensing element.
