Description

Control device of thermal deaerator Technical Field The utility model relates to the technical field of thermal deaerators, in particular to a thermal deaerator control device. Background The thermal deaerator is a device for removing dissolved oxygen and other non-condensable gases in water by heating, and is mainly used for a boiler water supply system. The control of the thermal deaerator is the key for ensuring the high-efficiency and stable operation of the thermal deaerator, and is mainly realized by adjusting parameters such as temperature, pressure, water level, gas discharge and the like. According to henry's law, the water temperature needs to reach the saturation temperature under the corresponding pressure to effectively separate out the dissolved oxygen. The thermal deaerator monitors the temperature in real time through a temperature sensor and a PID controller, and automatically adjusts the opening of a steam valve. The general PID controller is installed on the control cabinet, but some installation areas of the thermal deaerators are not suitable for installing the control cabinet, the PID controller is required to be independently installed, and the PID controller is inconvenient to fix. In view of this, we propose a thermal deaerator control device. Disclosure of utility model The utility model aims to provide a control device of a thermal deaerator, which is used for solving the problems in the background technology. In order to achieve the aim, the utility model provides the technical scheme that the control device of the thermal deaerator comprises a PID controller main body, wherein the bottom of the PID controller main body is provided with a connecting structure; The connecting structure comprises a T-shaped block and a connecting plate; the top of the T-shaped block is inserted into a jack formed in the bottom of the PID controller main body; wherein, the two ends of the top of the T-shaped block are fixedly connected with the PID controller main body through fixing components respectively; the connecting plate is fixedly arranged at the bottom end of the T-shaped block; the fixed component comprises a movable block, a positioning block and a telescopic rod; the top of the movable block is movably arranged in a perforation A on the T-shaped block; The positioning block is fixedly arranged at one side of the top of the movable block; The positioning block is in penetrating fit with a through hole B formed in the side end of the top of the movable block, and one end of the positioning block is in inserting fit with a positioning hole formed in the side wall of the jack; The telescopic rod is arranged between the movable block and the T-shaped block; And a spring is arranged between the movable block and the T-shaped block.
