Abstract

The utility model discloses a valve vibration reduction support structure which is arranged on a valve flange, wherein the vibration reduction support comprises a U-shaped section and connecting sections arranged at two ends of the U-shaped section; the connecting section is provided with a bolt hole, and the bolt penetrates through the bolt hole to be connected with the fixing surface; a first rubber pad is arranged between the contact surface of the valve flange and the U-shaped section, and a second rubber pad is arranged between the contact surface of the valve flange and the fixing surface. The valve vibration damping support structure is directly connected with the valve flange, not only can the valve be restrained up and down, but also horizontal friction force can be generated on the vibrating valve through bolt pre-tightening, so that horizontal vibration can be restrained, and meanwhile, a rubber pad is arranged between the valve vibration damping support structure and the valve flange to reduce vibration influence.

Description

Valve damping support structure

Technical Field

The utility model relates to the field of valve vibration reduction, in particular to a valve vibration reduction support structure.

Background

In petrochemical device, often can meet governing valve pipeline vibration phenomenon, can only reduce pipeline vibration through setting up the support (as shown in fig. 2) on the pipeline, valve body vibration often can not be solved, and long-time valve vibration can produce harm to the valve body, influences device production safety.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provides a valve vibration reduction support structure.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the vibration reduction support structure of the valve is provided, and is arranged on a valve flange, and comprises a U-shaped section and connecting sections arranged at two ends of the U-shaped section; the connecting section is provided with a bolt hole, and the bolt penetrates through the bolt hole to be connected with the fixing surface; a first rubber pad is arranged between the contact surface of the valve flange and the U-shaped section, and a second rubber pad is arranged between the contact surface of the valve flange and the fixing surface.

Further, the number of the bolt holes is two.
