Problems solved by technology

Now many automatic drain valves adopt the inverted bucket type, such as inverted bucket steam traps, inverted bucket compressed air drain valves, etc., the automatic drainage capacity is very good, but due to factors such as different working conditions and media, it often leads to The drain valve is blocked, and the draining effect is poor.
Especially for the working condition of the oil-injected screw air compressor, the inverted bucket drain valve is often easily blocked. The reason is that the air compressor is an oil-injected screw machine, and the compressed air contains oil. Valve cavity structure) The oil film is easily formed at the top of the emptying nozzle, which hinders the discharge of air from the emptying nozzle, causing a large amount of gas to accumulate in the cavity, making it impossible for the inverted bucket to sink, the valve cannot be opened, and the condensed water cannot be discharged

Abstract

The invention relates to an inverted bucket type drain valve applicable to compressed air with oil. The inverted bucket type drain valve comprises a valve (1), a valve seat (2), a valve element (3), a valve bonnet (4) and a dredging pin (6). A connecting pipe (8) is arranged in the valve (1), an inverted bucket (7) sleeves the connecting pipe (8) and is in transmission connection with the valve element (3), a sealing pair is formed by the valve element (3) and the valve seat (2), a drain nozzle (5) is arranged on the top of the inverted bucket (7), the dredging pin (6) is penetratingly arranged in the drain nozzle (5), and the top of the dredging pin (6) is suspended on the inner top of the valve (1). Compared with the prior art, the inverted bucket type drain valve has the advantages that buoyancy force of the inverted bucket can be guaranteed, the oil film breaking capacity can be improved, the drain valve can be effectively prevented from being blocked, and the like.

Description

technical field [0001] The invention relates to an inverted bucket type liquid discharge valve, in particular to an inverted bucket type liquid discharge valve suitable for oily compressed air. Background technique [0002] In the field of steam and compressed air manufacturing process, automatic drain valve is an indispensable device, which is used to remove condensed water in steam and compressed air. Now many automatic drain valves adopt the inverted bucket type, such as inverted bucket steam traps, inverted bucket compressed air drain valves, etc., the automatic drainage capacity is very good, but due to factors such as different working conditions and media, it often leads to The drain valve is blocked, and the drain effect is poor. Especially for the working condition of the oil-injected screw air compressor, the inverted bucket drain valve is often easily blocked. The reason is that the air compressor is an oil-injected screw machine, and the compressed air contains ...
