Self-acting temperature regulator

Self-acting temperature regulator

Direct-acting temperature regulator is a pipeline valve designed for automatic maintenance of a set water temperature.

The regulator automatically maintains the water temperature by changing the valve flow area controlled by the thermostatic element and does not require an additional source of energy.

The principle of operation of the direct-acting temperature regulator is based on the use of phase transition energy and thermal expansion of the working fluid in the closed space of the temperature sensor to change the valve flow area. Depending on the response to an increase in water temperature, regulators are divided into those that open with increasing temperature and those that close.

Scope of application

The regulator can control the heat transfer of a rapid heat exchanger, provide heating of water to a set temperature in the tank of a water heater, or control the water flow in the circulation pipeline of a hot water supply system.

The most widespread use of temperature regulators has been in hot water supply systems to control the flow of heating fluid according to changing needs for hot water.

Advantages

  • Low price
  • Simple design
  • High reliability
  • Easy adjustment
  • No external source of energy required

Disadvantages

  • High requirements for the quality of the heat transfer fluid.
  • The temperature setting can only be changed manually.
  • The distance to the temperature sensor is limited by the length of the impulse tube.
  • The adjustment range is limited by the characteristics of the thermostatic element.
  • The accuracy of temperature maintenance decreases when the setting temperature deviates from the middle value to the boundary values of the adjustment range.

Equivalent names

  • Automatic water temperature regulator
  • Thermostatic regulator (valve)

What can it be replaced with

  • A temperature regulator of indirect action based on a programmable controller, a temperature sensor, and a control valve.
