Description

Multi-pipe water seal

Technical Field

The utility model relates to a multitube water seal.

Background

The overflow water seal is one of important equipment in power plant production, generally disposes the oxygen-eliminating device for, the oxygen-eliminating device is used for getting rid of the oxygen and other noncondensable gases in the feedwater, guarantees the feedwater quality, and the overflow water seal can prevent that external gas from getting into, and when the liquid level was higher than the highest safe water level, unnecessary water can be discharged, and when the too much internal pressure of steam exceeded normal operating pressure, unnecessary steam can be got rid of and the pressure release, prevents the superpressure danger.

The overflow water seal in the prior art is integrated with a device needing to be used, so that the device is complex in overall structure, high in production cost, complex in installation and maintenance, short in service life and incapable of meeting the increasing production requirement.

SUMMERY OF THE UTILITY MODEL

The utility model provides a multitube water seal, its purpose aims at overcoming the realization that prior art exists not enough, realizes simplifying the structure, reduction in production cost, increase of service life.

The technical solution of the utility model is as follows: the multitube water seal, its structure includes two parallel arrangement's outer tube, the channel-section steel is passed through to two lateral surface lower parts and is connected, the apron is established to the outer tube upper end, internal thread beam section and vex head are established to the outer tube lower extreme, establish a return bend in two outer tubes respectively, the return bend lateral surface passes through the fixed plate and is connected fixedly with the outer tube medial surface, one side return bend upper end and opposite side outer tube side are connected, opposite side return bend upper end is extended to correspond the outer tube lateral surface and is established the flange outward, the takeover is established on one side outer tube lateral.

Preferably, the distance between the central lines of the two outer pipes is 300mm, the length of the outer pipe is 2150mm, the inner diameter of the outer pipe is 159mm, the inner diameter of the bent pipe is 89mm, the length of the vertical section is 1470mm, the bending angle is 45 degrees, and the length of the threaded pipe is 60 mm.

The utility model has the advantages that: simple structure is effective, through setting up two sets of outer tubes and return bends, has realized the convenient work of overflow water seal, through setting up screwed pipe and takeover, conveniently is connected the installation with the device that needs the overflow water seal, has simplified the installation and has maintained, has prolonged life, has reduced manufacturing cost, very is fit for using widely.
