Integrated draining device

Abstract

The invention discloses an integrated draining device. The device comprises a valve body, wherein a valve cover is arranged on the valve body and a housing space is formed in the valve cover; a first channel into the housing space from the valve body; a draining assembly, wherein the draining assembly comprises a piston cavity which is formed in the valve body and communicated with the housing space, a draining switch is arranged at the communication position of the piston cavity and the housing space, and a piston connected with the draining switch is arranged in the piston cavity; a starting assembly, wherein the starting assembly comprises a second channel and a floating ball accommodated in the housing space, the two ends of the second channel are respectively communicated with the housing space and the piston cavity, a starting switch is arranged at the communication position of the second channel and the housing space, and the floating ball is connected with the starting switch; the floating ball drives the starting switch to be opened and closed, and an opening communicated with the outer part of the integrated draining device is arranged on the part of the piston cavity near to the housing space. When a steam power system runs, the water can be automatically drained in time, and steam leakage can be prevented; the device is compact in structure and the space can be effectively saved.

Description

technical field [0001] The invention relates to the field of water-repelling devices, in particular to an integrated water-repelling device integrating functions such as water repelling, bypass and cut-off. Background technique [0002] At present, the drainage system of steam-powered ships in my country usually adopts single-unit steam traps, and is equipped with front and rear stop valves and bypass valve structures to drain and collect water (steam and condensed water) in various steam-water pipelines in the entire steam power system. And discharge the condensed water, air and non-condensable gas accumulated in the equipment or steam pipeline to the outside of the steam power system, while trying to avoid steam leakage. With the increase of the power of the ship's steam power system, the existing single-unit traps cannot timely drain water when the steam power system is running, and cannot guarantee the normal operation of the high-power steam power system. Although the e...

Problems solved by technology

With the increase of the power of the steam power system of the ship, the existing single traps cannot timely drain water when the steam power system is running, and cannot guarantee the normal operation of the high-power steam power system

Although the existing stand-alone steam traps can be installed directly on ships, due to the small space in the cabin and dense pipelines, it is very inconvenient for construction and maintenance operations; Usually takes up a lot of space, not suitable for ships with strict space requirements
