Description

Technical Field

[0001] The utility model relates to the field of steam pipe network systems, in particular to a two-stage adjustable condensate drainer. Background Art

[0002] The function of the steam trap is because only steam is needed on the equipment using steam, and this kind of heat-using equipment will definitely produce condensed water during heat exchange. The condensed water will absorb the steam energy and reduce the steam quality, reduce the steam enthalpy value and thus reduce the heat exchange rate. The condensed water becomes a harmful fluid and is also mixed with air and other non-condensable gases, which becomes the cause of equipment failure and reduced performance.

[0003] Generally, the discharged condensate has a range of fluctuations. For example, due to seasonal temperature differences, the flow rate will be small in summer and large in winter. If the existing discharger phase change nozzle is not adjustable, the heat loss cannot be controlled, which is not conducive to energy saving and efficiency improvement. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a two-stage adjustable condensate drainer, which can selectively adjust the first-stage phase change flow switch according to the change of seasonal temperature difference, reduce the heat energy loss and waste in the steam heating process, and achieve efficiency improvement and energy saving effects.

[0005] The technical solution of the present application is: a two-stage adjustable condensate drainer, comprising a main shell, an upper pressure cover connected to the steam inlet end of the main shell and a lower connecting piece welded to the lower end of the main shell, the bottom of the lower connecting piece is connected to the steam outlet, a two-stage phase change nozzle and a nozzle pressure ring are provided in the middle of the main shell, the lower part of the upper pressure cover is connected to the filter bone sleeve, a filter is provided in the filter bone sleeve, the two-stage phase change nozzle is communicated with the steam outlet, a transverse connecting hole is provided in the lower connecting piece, an adjusting valve stem is provided in the connecting hole, the adjusting valve stem passes through one of the first-stage phase change nozzles, and an axial hole is provided on the adjusting valve stem at the connection with the phase change nozzle.

[0006] The depth of the connecting hole does not touch the phase change nozzle on the other side.

[0007] An O-ring is arranged between the regulating valve stem and the connecting hole located outside the phase change nozzle.

[0008] An axial hole is transversely arranged on the phase change nozzle, the diameter of the regulating valve stem is smaller than the diameter of the axial hole, and the regulating valve stem can rotate in the axial hole of the phase change nozzle.

[0009] The outer end of the regulating valve stem is provided with a connecting groove, and the rotating regulating rod is installed in the connecting groove.

[0010] The advantages and beneficial effects of the present application are as follows: the present application utilizes the phase change nozzle steam-liquid two-phase flow condensation principle to quickly discharge the steam condensate generated by pipeline heating in the steam pipe network system; since the steam heating flow value of the pipe network system fluctuates less due to seasonal ambient temperature changes, the first-level phase change flow switch can be selectively adjusted according to the seasonal temperature difference, thereby reducing the heat energy loss and waste in the steam heating process and achieving efficiency improvement and energy saving effects.
