A quick release steam trap

Abstract

The present invention relates to a quick release steam trap. The characteristics of the present invention are: the left side of the Y-shaped valve body is provided with a water inlet, and the right side is provided with a water outlet; the gasket groove I and the gasket groove II on the bottom surface of the valve seat are respectively filled with gaskets I and II; The upper end is equipped with a C-shaped expansion ring and a supporting pad in turn. A valve seat is installed in the cavity at the upper end of the Y-shaped valve body, and a ∧-shaped groove valve plate is placed on the upper end of the valve seat. The inner platform bonnet is threadedly connected to the upper cavity of the Y-shaped valve body; the semicircular boss in the air isolation cover is nestedly connected to the semicircular groove on the upper side of the Y-shaped valve body. The step hole at the lower end of the Y-shaped valve body is equipped with a filter screen, the screw plug is equipped with a sealing gasket III, and the screw plug is threaded with the step hole. The invention solves the fatal defect that the thermodynamic steam trap cannot automatically discharge air and non-condensable gas, and at the same time improves the performance and service life of the thermodynamic steam trap. It can replace manual, electric and pneumatic valves, with reliable action, remarkable environmental protection effect, high parameters and low price.

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...
