Abstract
The utility model discloses a kind of pipeline valve vibration damping equipment, comprise rubber expansion joint, valve, pipeline and damping assembly, wherein rubber expansion joint one end crosses with device for cleaning pipeline that flangeseal is connected, the other end is connected by flangeseal with valve, and valve is tightly connected respectively by flange plate and rubber expansion joint and pipeline; Damping assembly comprises steel spring, screw mandrel and connecting sheet, and screw mandrel is two one group, is arranged at steel spring two ends respectively, and steel spring length is less than rubber expansion joint length; Connecting sheet is corresponding one by one with screw mandrel, and the screw mandrel at steel spring two ends is connected respectively to rubber expansion joint two ends by connecting sheet.Damping assembly is arranged at rubber expansion joint outside by connection strap and screw mandrel by steel spring good effectiveness in vibration suppression, and organically forms a whole with rubber expansion joint.In the internal structure situation that does not change pipeline and rubber expansion joint, improve the pipe vibration that pipeline valve causes in the time that switch is closed.
Description
Technical field
The utility model belongs to vibration damping field, is specifically related to a kind of pipeline valve vibration damping equipment.
Background technique
Pipeline valve can cause the parameters such as the pressure, speed, density of pipe stream to present periodic variation with position in time in the time that switch is closed, thereby causes pipe vibration.Pipe vibration tends to produce low frequency noise, thereby therefore impact living environment around, need to effectively administer this phenomenon.In prior art, the method conventionally adopting for this problem is in pipeline, to be provided with rubber expansion joint.Although this method can be at the pipe vibration that pipeline valve causes in the time that switch is closed that improves to a certain degree, it is unsatisfactory that it improves effect.Because rubber expansion joint need to possess unique performance, therefore on damping property, need to have a greatly reduced quality, but the material of rubber expansion joint itself with in structure, improve relative difficulty, do not take too many installing space so be badly in need of one, again the effective device of the pipe vibration causing in switch when closure for pipeline valve of Optimization Vibration effect.
Model utility content
It is a kind of simple in structure, easy to use that the utility model object is to provide, and can effectively improve the pipeline valve vibration damping equipment of the pipe vibration that pipeline valve causes in the time that switch is closed.
A kind of pipeline valve vibration damping equipment, comprise rubber expansion joint, valve, pipeline and damping assembly, wherein rubber expansion joint one end crosses with device for cleaning pipeline that flangeseal is connected, the other end is connected by flangeseal with valve, and valve is tightly connected respectively by flange plate and rubber expansion joint and pipeline; Damping assembly comprises steel spring, screw mandrel and connecting sheet, and screw mandrel is two one group, is arranged at steel spring two ends respectively, and steel spring length is less than rubber expansion joint length; Connecting sheet is corresponding one by one with screw mandrel, and the screw mandrel at steel spring two ends is connected respectively to rubber expansion joint two ends by connecting sheet.
For making the utility model more be suitable for practicality, make further improvements below:
Described steel spring arranged outside has metallic case, makes the movement locus of steel spring be restricted to radial motion, to reach better effectiveness in vibration suppression.
Described damping assembly is set to four groups, is arranged at respectively surrounding outside rubber expansion joint.
Described connecting sheet is long strip, and long strip one end connection wire rod, the other end connect the wherein flange plate of one end of rubber expansion joint.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, and damping assembly is arranged at rubber expansion joint outside by connecting sheet and screw mandrel by steel spring good effectiveness in vibration suppression, and organically forms a whole with rubber expansion joint.Under the material and structure situation that do not change pipeline and rubber expansion joint, improve the pipe vibration that pipeline valve causes in the time that switch is closed.Reach the object that improves effectiveness in vibration suppression under the prerequisite that does not affect other performances of rubber expansion joint.
