Quick-unlocking steam hydrophobic valve

Abstract

The invention relates to a quick-unlocking steam hydrophobic valve. The quick-unlocking steam hydrophobic valve is characterized in that a water inlet is formed in the left side of a Y-shaped valve body, and a water outlet is formed in the right side of the Y-shaped valve body; a sealing gasket I and a sealing gasket II are arranged in a gasket groove I and a gasket groove II in the bottom face of a valve seat; a C-shaped tensioner ring and a supporting cushion are arranged at the upper end of the valve seat in sequence; the valve seat is arranged in a cavity in the upper end of the Y-shaped valve body, and an inverted-V-shaped groove type valve plate is placed at the upper end of the valve seat; an inner table type valve deck is connected with a thread in the cavity in the upper end of the Y-shaped valve body; a semicircular boss in an air isolation hood is connected with a semicircular ring groove in the side face of the upper end of the Y-shaped valve body in a nested mode; a filter net is arranged in a stepped hole in the lower end of the Y-shaped valve body, a sealing gasket III is arranged in a plug screw, and the plug screw is connected with the stepped hole in a threaded mode. According to the quick-unlocking steam hydrophobic valve, the fatal defect that a thermo-motive type steam hydrophobic valve cannot exhaust air and non-condensable gas automatically is overcome, meanwhile, the performance of the thermo-motive type steam hydrophobic valve is improved, and the service life of the thermo-motive type steam hydrophobic valve is prolonged. A manual, electric and pneumatic valve can be replaced, the action is reliable, the environment-friendly effect is obvious, parameters are high and cost is low.

Description

technical field [0001] The present invention relates to a steam trap, and more particularly to a quick release steam trap that quickly discharges air and noncondensable gases. Background technique [0002] At present, domestic high-pressure thermodynamic steam traps all have the problem of not being able to discharge air and non-condensable gases. Air and non-condensable gas fill the cavity of the trap, preventing condensed water from entering the trap, causing the condensed water to stay in the steam pipe, affecting the heat exchange rate of the heating equipment and causing water hammer in the steam pipe. Severe water hammer can cause the The steam pipe is torn at the bend. Contents of the invention [0003] The technical problems to be solved by the present invention are: how to get rid of the air and non-condensable gas in the trap, and quickly start the trap function of the valve; , in order to weaken the interference of the secondary steam on the inlet flow; how to...
