High flow rate circular plate dual metal type steam bleeder

Abstract

The invention relates to a circular plate bimetallic type steam drain valve featuring large drainage capacity. The valve is characterized in that an inner cavity of a valve body (11) is provided with a filtering net (12), the centers of a water inlet hole (24) and an a water outlet hole (25) respectively at the left side and right side of the valve body (11) is on the same axis, screw holes (26) are evenly distributed at the bottom part of the inner cavity of the valve body (11) to communicate with the water outlet hole (25). Positioning pins (4) are symmetrically arranged at the upper part of the valve body (11) to position with a valve cover (2), a screw bolt (17) is used to tighten the positioning pins (4) and the valve cover (2); the valve cover (2) is connected with a valve bonnet (21) by a screw thread. A small head end of a valve seat (8) is connected with the screw holes, the outer diameter of the valve seat (8) is sheathed with a spring (7), the inner cavity is provided with a support (6), the support (6) is internally provided with a core sleeve (5), the core sleeve (5) is internally provided with a core shaft (3), the core shaft (3) is provided with a bimetallic strip group (14) which is positioned by an E-shaped clamp spring (13), an adjusting bolt (20) is connected with the valve cover (2) in thread. The steam drain valve of the invention features high operation reliability, contribution to recovery of condensed water, elimination of air blocking and steam locking, agile and reliable movement, low noise, long service life, convenient horizontal installation and easy maintenance.

Description

technical field [0001] The present invention relates to a bimetallic steam trap, more specifically to a large-displacement steam trap that can meet the requirements of steam pipelines to remove condensed water and non-condensable gas and prevent steam leakage, and is conducive to the recovery and utilization of condensed water. Disc bimetallic steam trap. Background technique [0002] At present, the known disc bimetallic steam traps have a relatively small displacement and cannot meet the requirement of a large displacement. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the defect of small displacement of the existing disc bimetallic steam trap, and to provide a steam trap with a large displacement range, good stability and reliability, automatic centering and automatic valve closing. Large displacement disc bimetallic steam trap. [0004] In order to solve the above-mentioned technical problems, the prese...
