Energy-saving temperature controlled automatic trap

Abstract

The invention relates to a drain device in a heating system, and especially relates to a temperature controlled automatic trap. The temperature control automatic trap is characterized by comprising a magnetic valve type trap valve body, a temperature controlled switch, a control circuit board, and a magnetic valve type trap coil. The temperature controlled switch is installed on the inlet of the magnetic valve type trap valve body, and achieves an objective of measuring temperature through indirect contact of the metal valve body, water, and a steam medium. The control circuit board is installed in the external wiring housing of the magnetic valve type trap coil. The magnetic valve body is connected with the return pipeline in a heating region, and is directly connected with the heating return pipeline. The valve body and the pipeline are connected in a flange or screw thread manner. The temperature controlled switch and the valve body are connected in an embedded or screw thread manner. The temperature controlled automatic trap is characterized by small volume, simple and compact structure, flexible operation, low cost, and wide application range, and saving energy. The trap can be widely applied in the drain device in the heating system, and can realize automatic control by just one-time temperature setting.

Description

technical field [0001] The invention relates to a drainage device in a heating system, in particular to an energy-saving temperature-controlled automatic drainage device. Background technique [0002] At present, the steam traps traditionally used in China are of floating barrel type and pressure type structure. In use, there are: steam traps cause energy waste; there is hysteresis control or human intervention control for temperature control, and it is easy to cause accidents and economic losses. In the known technology, steam metering temperature control composite electronic steam trap is used, which is composed of four devices: liquid storage, water meter, electronic control and water separation. This steam trap has the defects of complex structure, large volume and high cost. Contents of the invention [0003] The present invention overcomes the above-mentioned defects, and aims to provide an energy-saving temperature-controlled automatic steam trap with a simple and c...

[0002] At present, the steam traps traditionally used in China are of floating bucket type and pressure type structure. In use, there are: steam traps cause energy waste; there is hysteresis control or human intervention control for temperature control, and it is easy to cause accidents and economic losses.

In the known technology, steam metering temperature control compound electronic steam trap is used, which is composed of four devices: liquid storage, water meter, electronic control and water separation. This kind of steam trap has the defects of complex structure, large volume and high cost
