Abstract
The invention relates to a thermodynamic steam trap valve, which sequentially comprises a valve cover, a valve plate, a label rivet, a valve body, an inlet, an outlet, a filter screen and a plug, wherein the upper part of the valve cover is internally provided with the filter screen, the upper part of the valve body is in threaded connection with the valve cover, and the lower part of the valve body is in threaded connection with the plug.
Description
Technical Field
The utility model relates to a valve field, concretely relates to thermal power type steam trap.
Background
Steam systems are widely used in modern equipment, and drainage and exhaust in steam systems are very important, which means that a device is needed, condensed water, air and other non-condensable gases in steam can be automatically exhausted, steam can be prevented from escaping, further, on a steam conveying pipeline, the steam is guaranteed to be as dry as possible when reaching a steam using point, water hammer and corrosion are avoided, and high-quality steam can be more effectively provided for steam equipment.
Disclosure of Invention
In view of the above problems, it is an object of the present invention to provide a device that is applicable to a steam pipeline and can automatically discharge condensed water in the steam pipeline.
The utility model discloses the technical scheme who takes as follows:
the utility model provides a thermal power type steam trap, includes valve gap, valve block, sign rivet, valve body, entry, export, filter screen, plug in proper order, characterized by:
the valve cover part is provided with a label in the upper hole and connected with the label through a rivet, the plug part is internally provided with a filter screen,
the upper part of the valve body part is in threaded connection with the valve cover, and the lower part of the valve body part is in threaded connection with the plug;
further: the valve plate part is arranged in a cavity formed by the valve cover and the valve body and can freely move up and down;
further: the upper end of the filter screen part is arranged in the valve body, and the lower part of the filter screen part is arranged in the pipe plug;
further: the two ends of the valve body are connected in a mode that an inlet and an outlet are connected through threads or welded or flanged, and the connection requirement of more than 95% of the current working condition occasions can be met.
The utility model discloses, can use on the steam pipeline, can be automatically with the interior condensate water discharge of steam to have simple structure, simple to operate, water-resistant hammer, the characteristics of anti-vibration.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in fig. 1-3, a thermodynamic steam trap sequentially comprises a valve cover, a valve plate, a label rivet, a valve body, an inlet, an outlet, a filter screen and a plug, wherein the label is arranged in an upper hole of the valve cover and connected with the label rivet, the filter screen is arranged in the plug, the upper part of the valve body is in threaded connection with the valve cover, and the lower part of the valve body is in threaded connection with the plug;
the valve block part and the valve block are arranged in a cavity formed by the valve cover and the valve body and can move up and down freely, the upper end of the filter screen part is arranged in the valve body, the lower part of the filter screen part is arranged in the pipe plug, and the two ends of the valve body are connected in a mode that an inlet and an outlet are connected through threads or welded or connected through flanges, so that the connection requirement of more than 95% of the current working condition occasions can be met, the connection requirement can be selected according to the actual requirement, and the limitation is not required.
In this embodiment, as shown in fig. 3, when the valve is started for the first time, steam enters from the inlet and enters the lower portion of the valve plate through the filter screen cavity, fig. 4 is a structure without a filter screen, i.e., a medium can directly enter the lower portion of the valve plate from the inlet, at this time, the valve plate is jacked up by the steam due to the pressure, and cold condensate and air are rapidly discharged, i.e., the state shown in fig. 2; steam continuously enters, hot condensed water generates secondary steam when flowing through the drain valve again, high-speed secondary steam forms low pressure below the valve plate, the valve plate is pulled downwards, meanwhile, the secondary steam enters the upper space of the valve plate to force the valve plate to move downwards, at the moment, the pressure above the valve plate is larger than the lower pressure, so that the valve plate is forced to press downwards and tightly press on the upper plane of the valve body, the drain valve is forced to be closed, and the state of the figure 3 is returned; and the pressure is reduced again along with the condensation of the secondary steam, the valve plate is jacked up by the inlet pressure again, namely, the state of the figure 2 is returned again, the reciprocating circulation is started, and the condensed water in the steam is automatically discharged from the outlet.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
