Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in figures 1-3, a disc type thermodynamic steam trap with a thermal insulation cap sequentially comprises a thermal insulation cap, a valve cover, a valve plate, a valve seat sealing gasket I, an inlet, a valve body, a filter screen, a plug, a thermal insulation cavity, a valve cover sealing gasket, a thermal insulation cap sealing gasket, a valve seat sealing gasket II and an outlet.
The valve body part, upper portion and lower part are connected with the valve gap, and the lower part and the plug are connected.
The valve plate part is arranged in a cavity formed by the valve cover and the valve seat and can move up and down; the heat-insulating cavity part is externally provided with a heat-insulating cap, and the interior of the heat-insulating cavity part is a valve cover part and is in threaded connection with the valve body; 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; the two ends of the valve body are connected in a threaded connection mode, namely an inlet and an outlet, or in a welded connection mode or in a flange connection mode, 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 no limitation is imposed on the connection mode.
In this embodiment, as shown in fig. 2, during the initial start, steam enters from the inlet and enters the lower portion of the valve plate through the filter screen cavity, at this time, the valve plate is jacked up by the steam due to the pressure, and cold condensed water and air are rapidly discharged, that is, 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. Simultaneously in this embodiment, because there is the heat preservation chamber on upper portion, reducible external environment temperature reduces the valve block spring frequency to the change of temperature in the valve gap, reduces the damage of valve block and the sealed face of valve body, extension valve live time.
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.
