Abstract

The invention discloses a lever pilot type superheated steam drain valve for an inverted barrel and relates to a drain valve, in particular to the lever pilot type superheated steam drain valve for an inverted barrel. The invention provides the lever pilot type superheated steam drain valve for the inverted barrel, the upper and lower sealing structures of a pilot valve of which have the advantages of even contact of spherical sealing surface, stable and reliable performance, long service life, easiness to maintain and the like. The drain valve is provided with the lever pilot valve, a valve cover, a sealing gasket, a valve body, the inverted barrel and a collecting basin part; the lever pilot valve is positioned at the lower end of the outlet of the valve cover, the collecting basin partis positioned at the inlet of the lower end of the valve body and the sealing gasket is arranged in the sealing groove of the valve body; the valve cover covers the valve body and the inverted barrelis positioned on the collecting basin part.

Description

Technical field [0001] The present invention involves a hydrophobic valve, especially a leveraged pilot inverted inverted barrel overheating steam hydrophobic valve. Background technique [0002] The existing leverage pilot inverted bucket overheating steam water sparse valve is mainly composed of leveraged pilot valve components, valve lids, sealing pads, valve bodies, inverted buckets, pools and other components.When the stop valve is turned on to enter the pond, the condensation level in the collection of the pool gradually increases.Because the buoyancy supports the auxiliary valve and close the intake pipe, the coagulation water forms a water seal in the pond, and the coagulation diameter is entered the inner cavity of the valve body from the water inlet pipe.When the water level rises to a certain height, the pressure of the valve body is balanced with the pressure in the pipeline, and the return valve will be closed. After the steam in the inverted barrel gradually condens...
