Abstract
The utility model is related to a kind of pipelines with bellows structure, including pipeline, it is provided with high-pressure ball valve on the pipeline, the outlet end of the high-pressure ball valve is provided with bellows, the bellows is double-ply bellows, it is supported and is connected by flange between two layers of bellows, the inner and outer wall of two layers of bellows is both provided with anticorrosive metal layer.The utility model passes through the bellows structure that is arranged on pipeline, have the function of damping and absorption line sedimentation and deformation, it is easy to cause mechanicalness to tear in pipeline in excessive temperature differentials or excessive vibrations, the heating steam port being arranged on bellows can effectively keep the temperature pipeline, securely and reliably.
Description
Technical field
The utility model is related to a kind of assembly equipment more particularly to a kind of pipelines with bellows structure.
Background technology
In industrial detection, detecting electrode usually requires also to be collected detection to detection liquid on pipeline, but general
Logical pipeline cannot be bent, and also not have the function of damping and absorption line sedimentation and deformation, in excessive temperature differentials or vibrations
It is easy to cause mechanicalness to tear in pipeline when excessive, maintenance cost is high.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of pipeline with bellows structure.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes pipeline, and high-pressure ball valve, the outlet end setting of the high-pressure ball valve are provided on the pipeline
It is double-ply bellows to have bellows, the bellows, is supported and is connected by flange between two layers of bellows, two layers of wave
The inner and outer wall of line pipe is both provided with anticorrosive metal layer.
Specifically, it is both provided with heating steam port on the pipeline and bellows.
Specifically, the bellows is metal bellows.
Specifically, the metallisation layer protected against corrosion is nickel-cadmium layer or tin chromium alloy layer.
The beneficial effects of the utility model are：
The utility model is by the bellows structure being arranged on pipeline, the work(with damping and absorption line sedimentation and deformation
Can, it is easy to cause mechanicalness to tear in pipeline in excessive temperature differentials or excessive vibrations, the heating being arranged on bellows is steamed
Steam ports can effectively keep the temperature pipeline, securely and reliably.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1- high-pressure ball valves, 2- bellowss, 3- heat steam port.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the utility model includes pipeline, high-pressure ball valve 1, the high-pressure ball valve 1 are provided on the pipeline
Outlet end be provided with bellows 2, the bellows 2 is double-ply bellows, is supported by flange between two layers of bellows 2
Connection, the inner and outer wall of two layers of bellows 2 are both provided with anticorrosive metal layer.
Heating steam port 3 is both provided on the pipeline and bellows 2, the bellows 2 is metal bellows, described
Metallisation layer protected against corrosion is nickel-cadmium layer or tin chromium alloy layer.
The utility model is by the bellows structure being arranged on pipeline, the work(with damping and absorption line sedimentation and deformation
Can, it is easy to cause mechanicalness to tear in pipeline in excessive temperature differentials or excessive vibrations, the heating being arranged on bellows is steamed
Steam ports can effectively keep the temperature pipeline, securely and reliably.
Bellows has the shell of the cylinder-shaped thin wall wrinkle of multiple transverse waves, and bellows has elasticity, in pressure, axis
Displacement can be generated under Xiang Li, cross force or Moment, convert pressure into displacement or power.Ripple tube wall is relatively thin, sensitivity
Higher, measurement range is tens of pas to tens of megapascal.In addition, bellows is also used as seal isolation element, by two media
The measurement part separated or prevent harmful fluids from entering equipment.It is also used as compensating element, using its volume can
It is denaturalized the temperature error of compensation apparatus.It is also sometimes used as the resilient connection connector etc. of two parts.Multilayer corrugated pipe intensity is high,
Durability is good, and stress is small, is used in important measurement.
The material of bellows is generally bronze, brass, stainless steel, monel metal and inconel that alloy etc..
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
It protects in range.
