CN203463851U - Pipe connecting piece for vibration prevention and reduction - Google Patents

Abstract

A pipe connecting piece for vibration prevention and reduction comprises a main pipe, the side wall of the main pipe is provided with a concave hole, a branch pipe is inserted into the concave hole, the tail end of the branch pipe is connected with an elbow of 45 degrees, the contact portion of the branch pipe and the concave hole is connected with a flange, the periphery of the concave hole of the main pipe is connected with a flange, two flanges are fixed through a bolt, and the included angle between the central line of the branch pipe and the central line of the main pipe is between 45 degrees and 90 degrees. The pipe connecting piece for vibration prevention and reduction has the advantages that the flow direction of the branch pipe is changed at the connecting position of the main pipe and the branch pipe, so that great impact force due to the fact that substances of the branch pipe directly enter the main pipe can be reduced; delay of a construction progress or shutdown in a normal production process due to separation of a pipe and a support under certain impact force can be avoided.

Description

A kind of for pipe joint shockproof, damping

Technical field

The utility model relates to a kind of for pipe joint shockproof, damping, particularly a kind of link that is applicable to steam line with pressure.

Background technique

Industrial pipeline is in operation, media flow state flip-flop, and inertia and compressibility due to fluid, cause the phenomenon that in pipeline, pressure sharply rises or declines, and is called water (vapour) hammer (hitting).The momentary value of this class impact force may reach tens times to hundreds of times of normal operation pressure, make equipment and annex on pipe wall material and pipeline bear very large pressure, and follow the enlargement and contraction of pipeline, generation sharp pounding, pipe fitting joint break, disconnect, the consequences such as support damage, when serious, even the serious accidents such as pipe bursting be can there is, equipment and personal safety affected.Effective Shockproof damping, by the dead time that is conducive to the smooth running in production process and reduces system, minimizing accident occurs, and improves the operation ratio of system.

Model utility content

The purpose of this utility model has been to provide that a kind of this link is Shockproof damping effectively for pipe joint shockproof, damping, and the dead time that is conducive to the smooth running in production process and reduces system, minimizing accident occurs, and improves the operation ratio of system.

For reaching above-mentioned goal of the invention, the utility model by the following technical solutions:

This for pipe joint shockproof, damping, it comprises: supervisor, sidewall supervisor has a shrinkage pool, in shrinkage pool, insert arm, arm end connects one 45 ° of elbows, and arm is connected a flange with the contact position of shrinkage pool, and supervisor's shrinkage pool periphery connects a flange, between two flanges, with screw, fix, the angle of arm center line and supervisor's center line is between 45 °～90 °.

This link is by changing the flowing angle of fluid, and the impact force producing when buffer medium mixes, to reach the effect of Shockproof damping, improves operation ratio.

Advantage of the present utility model: this link is Shockproof damping effectively, the dead time that is conducive to the smooth running in production process and reduces system, minimizing accident occurs, and improves the operation ratio of system.

A kind of connecting-piece structure schematic diagram for pipeline with pressure that Fig. 2 provides for the utility model

The another kind of slurry that Fig. 3 provides for the utility model is by the connecting-piece structure schematic diagram of steam-heated pipeline

In Fig. 1, existing supervisor 1 linked together with being connected by welding manner of arm 2, and this structure can not be shockproof and damping.

In Fig. 2,3 is flanged supervisor's I, and 4 is flanged arm I, and 5 is 45 ° of elbow I, and 6 is screw I, and α is arm center line and the angle of being responsible for center line.

In Fig. 3,3 ' is flanged supervisor's II, and 4 ' is flanged arm II, and 5 ' is 45 ° of elbow II, and 6 ' is screw II.

Embodiment

Embodiment

As shown in Figure 3, this for pipe joint shockproof, damping, it comprises flanged supervisor's II 3 ', sidewall supervisor has a shrinkage pool, inserts flanged arm II 4 ' in shrinkage pool, and arm end connects one 45 ° of elbow II 5 ', arm is connected a flange with the contact position of shrinkage pool, supervisor's shrinkage pool periphery connects a flange, and fixing with screw II 6 ' between two flanges, arm center line is 90 ° with the angle of supervisor's center line.

Supervisor is the slurry pipeline of diameter DN400, by the steam branch pipe heating slurry of some DN50, adopt installation method of the present utility model: the slurry pipeline of diameter DN400 is connected with flanged supervisor's II two ends of this link respectively, and steam branch pipe is connected with one end of the flanged arm II of this link.Owing to having adopted after this link, by the effect of flange plate and angle, can reduce shockproof, the damping of pipeline.

Claims (1)

1. one kind for pipe joint shockproof, damping, it is characterized in that: it comprises: supervisor, sidewall supervisor has a shrinkage pool, in shrinkage pool, insert arm, arm end connects one 45 ° of elbows, and arm is connected a flange with the contact position of shrinkage pool, and supervisor's shrinkage pool periphery connects a flange, between two flanges, with screw, fix, the angle of arm center line and supervisor's center line is between 45 °～90 °.
