Problems solved by technology
[0004] However, because the device is integrated during installation, it can only be connected through flanges. Without multiple reinforcements, the installation may be unstable. The internal settings of the steam trap cannot be disassembled or replaced because they are sealed. Cleaning, and a single operation through the movable piece may cause a reset jam

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0023] see Figure 1 to Figure 4 , the present invention provides a thermodynamic steam trap for a steam turbine in a thermal power plant, comprising a steam trap main body 1 and a fixed cap 2, the top of the steam trap main body 1 is threadedly connected with a fixed cap 2, and both ends of the steam trap main body 1 are fixedly connected with a fixed ring 3 , the inner wall of the fixed ring 3 is sleeved with the connecting pipe 4. The inner wall of the fixed ring 3 is threaded to connect the limit bolt 5. One end of the limit bolt 5 penetrates the inner wall of the fixed ring 3 and connects with the surface of the connecting pipe 4. One end of the connecting pipe 4...

The invention discloses a thermal steam trap of a thermal power plant steam turbine. The thermal steam trap comprises a steam trap body and a fixing cap, wherein the two ends of the steam trap body are fixedly connected with fixing rings, the inner walls of the fixing rings are sleeved with connecting pipes, the inner walls of the fixing rings are in threaded connection with limiting bolts, one ends of the connecting pipes are in threaded connection with flange plates, and the surface of a supporting column is sleeved with a spring; and one end of the spring is fixedly connected with a movable piece. Through cooperative arrangement of the fixing rings and the limiting bolts, the limiting bolts are screwed to enable the connecting pipes to rotate in the fixing rings; and through cooperative arrangement of the connecting pipes and the flange plates, when the steam trap body does not need to be connected through the connecting pipes and the connecting pipes needs to be connected, the flange plates can be used for secondary reinforced connection, so that the purposes of multiple connection methods and reinforcement are achieved; and the movable piece can be reset through the elastic force of the spring, so that the situation that the movable piece is difficult to reset when being singly used is avoided.
Description
technical field [0001] The invention relates to the technical field of thermal drainage of steam turbines, in particular to a novel thermal drainage device for steam turbines in thermal power plants. Background technique [0002] Thermal steam trap is a kind of very strong steam trap with simple working method. This kind of steam trap works by the power generated by the flash steam passing through the steam trap. The condensate in the heated pipes is continuously drained out of the pipes. [0003] The turbine shaft seal heater steam trap disclosed in the Chinese invention patent application publication CN206280109U includes a bellows steam trap assembly and a pressure signal control assembly, the bellows steam trap assembly includes a bellows, and a limit device arranged on the bellows , a needle valve set on the upper part of the bellows, two water ports set on the lower part of the bellows, the pressure signal control assembly includes a pressure sensor, a pressure transm...
