Abstract
The purpose of this utility model is to provide a kind of blow-off line block clearing hand hole with blind plate.The technical solution of the utility model is: be made up of hand hole wall, flange, blind plate.First equidistant perforate above blow-off line, is welded on tapping by the block clearing hand hole of DN100, block clearing hand hole top welding flange, then is sealed by block clearing hand hole with blind plate.Like this after blocking in blow-off line, blocking position in blow-off line is judged easily via block clearing hand hole, and block clearing hand hole can be utilized to pass into rubber steam hose, and within a short period of time, clear and coherent pipeline, was difficult to clear and coherent phenomenon after avoiding longer bowl sewage draining pipeline blockage.This mechanism has that structure is simple, easy to operate and safety, operating efficiency are high, make and feature that maintenance cost is low.
Description
Technical field
The utility model relates to chemical industry, energy technology field, particularly relates to the block clearing hand hole that a kind of blow-off line uses.
Background technology
In process units wash still discharge pipe distance liquid waste processing pond far away, wash the waste water that still terminates rear releasing, concentration is larger, be easy to block blow-off line, be difficult to clear and coherent after long pipeline blocking, in order to address this problem, above blow-off line, equidistant perforate welding DN100 is with the block clearing hand hole of blind plate, there is this block clearing hand hole, blind plate when there is bowl sewage draining pipeline blockage by opening block clearing hand hole is easy to judge blocking position, and rubber steam hose can be passed into by block clearing hand hole, within a short period of time clear and coherent pipeline.
Utility model content
Based on above-mentioned technical problem, the purpose of this utility model is to provide a kind of blow-off line block clearing hand hole with blind plate.
Specifically, the technical solution of the utility model is: a kind of blow-off line block clearing hand hole with blind plate.It is characterized in that: be made up of blow-off line, hand hole wall, flange, blind plate, equidistant perforate above described blow-off line, described hand hole wall is positioned at above blow-off line, described hand hole wall tapping and blow-off line above blow-off line are welded to connect, described flange is positioned at above hand hole wall, described flange and hand hole wall are for being welded to connect, and described blind plate is positioned at above flange, and described blind plate and flange are that bolt is connected.
Further, described hand hole wall specification is DN100.
