Abstract
The invention relates to the field of water supply and drainage mounting technology and aims to provide a safer anti-falling off device for a channel bend which ensures that the bend part is uniformly stressed when a pipeline is subject to water hammering. The anti-falling off device comprises a first connecting piece arranged on the inner side of the bend, as well as a second connecting piece and a third connecting piece which are arranged on the outer side of the bend and correspond to the first connecting piece in position, and the second connecting piece and the third connecting piece are fixed with the first connecting piece through bolts. As the first connecting piece is connected and fixed with the second connecting piece and the third connecting piece through the bolts, when the pipeline is subjected to water hammering, the bend part can bear various nonuniform stresses, and various potential safety hazards are effectively eliminated.
Description
Technical field
The present invention relates to plumbing mounting technique field, especially relate to a kind of channel bend anti-drop device.
Background technique
As everyone knows, plumbing and fire-fighting system are because installation environment different, particularly fire fighting water system and its tubing of pressure drainage system in the subway generally is designed to hot dip galvanizing pipe, Placement is connected with groove by requirements such as standard, this Placement is the low reasons such as big and water pump start and stop are frequent with the ground difference of height in the mounting point of water pump in the subway in addition, the pipeline of the system that facts have proved from the suction point to the EXIT POINT is tortuous circuitous, various turn round many, when water pump operation opens, stopping time, water in the system pipeline will be gone out or will flow backwards rapidly when losing Driving force, will produce bigger water hammer (bump) in the corner of system pipeline, will the pipeline of building hanging part will be installed in when serious, and can't arrange evenly that the groove pipe fitting of stressed immovable point and pipe joint place hit to split to cause in a large number and metal run out, bring great hidden danger and influence safely for the Vehicle And Personnel of normal operation.
The claimant is to disclose a kind of elbow anti-drop device in 201120417345.9 in the patent No., this structure is passed through bolt by a U-bolt and anti-drop device main body, though it is simple in structure, cost is low, but when pipeline produces water hammer, the stressed of bend part is not very even, still has certain potential safety hazard.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind ofly when pipeline generation water hammer, bend part is stressed evenly, safer channel bend anti-drop device.
Channel bend anti-drop device of the present invention, comprise first link that is arranged on the elbow inboard, and being arranged on the elbow outside and position second link and three link corresponding with described first link, second link and the 3rd link all are fixed together by bolt and first link.
Further, described first link comprises first main body, the middle part of described first main body is provided with waist shaped hole, be equipped with first joint and second joint that can be adjacent to the elbow outer tube wall on the left and right two ends of described first main body, upper/lower terminal at described first joint extends the first bolt end respectively, extends the second bolt end respectively at the upper/lower terminal of described second joint.
Further, described second link comprises second main body, and the medium position of described second main body is provided with the 3rd joint that is adjacent to the elbow outer tube wall, and the upper/lower terminal of described the 3rd joint extends the 3rd bolt end respectively.
Further, described the 3rd link comprises the 3rd main body, and the medium position of described the 3rd main body is provided with the 4th joint that the elbow outer tube wall is adjacent to, and the upper/lower terminal of the 4th joint extends the 4th bolt end respectively.
Further, fix by first bolt between the described first bolt end and the 3rd bolt end.
Further, fix by second bolt between the described second bolt end and the 4th bolt end.
Compared with prior art, beneficial effect of the present invention is: integral body of the present invention is connected and fixed by bolt by first link and second link and the 3rd link, like this, when pipeline produces water hammer, bend part can bear the problem of various unbalance stress, eliminates all kinds of potential safety hazards effectively.
In addition, in order to adapt in the subway corrosion of moist and stray electrical current, the material of first link and second link and the 3rd link all is that employing centrifugal ductile cast iron is made.
