Problems solved by technology

At present, the existing hydrophobic devices can also play a good role, but when the pressure and temperature of the system are relatively high, there is often a relatively large thermal displacement, and because the pipeline is bent back and forth, there is not only vertical displacement, but also some Sometimes there will be lateral displacement, and the existing hydrophobic devices can only overcome the problem of thermal displacement in a single direction

Embodiment Construction

[0010] As shown in the figure, it includes: an exhaust pipe 1 , a drain pan 2 , a drain pipe 3 , an exhaust outlet pipe 4 , and a cover plate 5 .

[0011] In the figure, the exhaust pipe 1 extends into the exhaust outlet pipe 4 , the exhaust pipe 1 is provided with a drain pan 2 , and the drain pan 2 is provided with a drain pipe 3 . A cover plate 5 is arranged between the exhaust outlet pipe 4 and the drain tray 2 , and the cover plate 5 is placed on the drain tray 2 and is not fixedly connected to the exhaust outlet pipe 4 and the drain tray 2 . The distance that the exhaust pipe 1 protrudes into the exhaust outlet pipe 4 is 20-50 cm, preferably 30-40 cm.

[0012] The gap between the cover plate 5 and the exhaust outlet pipe 4 is 0.5-1cm. When the pipeline is exhausted, the drain plate 2 can well absorb the thermal displacement in the vertical direction, and because the cover plate 5 is not fixedly connected, the exhaust outlet There is also a certain thermal displacement s...

Abstract

The invention discloses a water draining disc with a movable cover plate, comprising a gas exhaust pipe, a gas exhaust outlet pipe, a water draining disc and a water draining pipe. The invention is characterized in that the gas exhaust pipe extends into the gas exhaust outlet pipe; the water draining disc is arranged on the gas exhaust pipe; the cover plate is arranged between the water draining disc and the gas exhaust outlet pipe in a movable way. By adopting the structure disclosed in the invention, since the cover plate is movable, heat displacement in vertical and horizontal directions can be released and solved.

Description

technical field [0001] The invention relates to a drainage device for pipelines, in particular to a drainage tray with a movable cover plate. Background technique [0002] The basic function of the drain tray is to discharge the condensed water, air and carbon dioxide gas in the steam system as soon as possible; at the same time, it can automatically prevent the leakage of steam to the greatest extent. There are many varieties of hydrophobic devices, each with different properties. When choosing a hydrophobic device, you should first choose its characteristics to meet the best operation of the steam heating equipment, and then consider other objective conditions, so that the choice of the hydrophobic device you need is correct and effective. At present, the existing hydrophobic devices can also play a good role, but when the pressure and temperature of the system are relatively high, there is often a relatively large thermal displacement, and because the pipeline is bent ba...
