Draining apparatus for steam conduit

Abstract

The invention discloses a steam pipeline drainage device. One end of a drainage pipeline (2) is connected with the steam pipeline and the other end is connected with a drainage tank (4). The drainage pipeline is connected with a drain valve bank (5) in the drainage tank (4). The device is characterized in that: the drainage pipeline (2) passes the drain valve bank (5) and then goes into the compartment of the drainage tank (4) through an intermediate diaphragm (7), a drain pipe (10) is arranged at the bottom of the compartment in drainage tank (4) and a steam discharge pipe (11) is arranged on the upside thereof; a case body (8) corresponding to the effluent direction of the drainage pipe in the compartment of the drainage tank (4) is made of thicken metal plate, the drain valve bank (5) supports on the supporting stand (6) in the drainage tank (4), and an access door (9) is positioned on the upside thereof. The device is applicable to the drainage of the steam pipeline, which ensures ground surface and surrounding objects to avoid being impacted directly by drainage gas and can provide protection to the drain valve bank. The device has the advantages of easy implementing, simple structure, low production cost and convenient assembling and disassembling.

Description

technical field [0001] The invention relates to a drainage device for steam pipelines, belonging to the technical field of steam pipelines. Background technique [0002] In the layout of steam pipelines in thermal power stations, after the low-point drainage uses the steam trap group corresponding to the steam pressure, there are no other protective measures. After long-term operation, due to no other protective measures, the valves are directly eroded by external substances (such as rainwater), causing the valves to The service life is reduced, and steam may leak from here, causing damage to personal safety and surrounding objects. In addition, even in normal steam drainage, the hydrophobic gas directly hits the ground or surrounding objects, and if it runs like this for a long time, it will cause great damage to the ground and surrounding objects. Therefore need to have a kind of device to protect this. Contents of the invention [0003] The technical problem to be sol...
