Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0044] Such as Figure 1a-Figure 1d As shown, a new type of spring damping device to deal with sudden changes in pipeline pressure, including three parts: the box, the baffle system and the spring system.

[0045] The box body 2 is symmetrically distributed at the front and rear ends, and its shape is a body of revolution formed by a curve rotating around the axis. The two ends are coaxially provided with outlets and inlets with the same diameter and used to connect the upper and lower gas pipelines. The connection means 1 and 8;

[0046] The baffle system includes a front baffle 3, a middle baffle 9 and a rear baffle 7, all of which are weld...

Abstract

The invention discloses a new spring damping device for coping with pipeline pressure jump, comprising a box body of which the front and rear ends are arranged symmetrically; the box body is a revolving body formed by a curve rotating around an axis for a circle, and both ends of the box body are coaxially provided with connecting devices with the same diameters used for connecting upstream and downstream gas pipelines; a damper system and a spring system are arranged in the box body, a spring coil in the spring system moves back and forth as the upstream gas pressure changes so as to drive 4 damper in the damper system to move, resulting in gas circulation area change, and the purpose of stabilizing pressure and flowrate is achieved. In the invention, no external energy or other substances are required, and the new spring damping device has the advantages of simple structure, easy installation and maintenance, and flexible speed adjustment; the influence of upstream pressure jump on downstream pipelines, instruments and equipment is reduced effectively to ensure the safe and steady operation of the pipeline.

Description

technical field [0001] The invention relates to a damping device for sudden changes in pipeline pressure, in particular to a novel spring damping device for sudden changes in pipeline pressure. Background technique [0002] With the popularization and use of natural gas and the country's vigorous promotion of energy-saving and emission-reduction projects, related natural gas comprehensive utilization technologies have developed rapidly. At present, equipment is developing in the direction of intelligence and refinement, which puts high demands on the stability of gas sources and natural gas operating conditions. requirements. Due to the different seasons, time and user needs of natural gas, or the sudden failure of upstream equipment, the downstream natural gas pressure or flow will change accordingly, which will cause different levels of impact on downstream equipment, and at the same time bring vibrations and reduce the downstream equipment. The service life and efficienc...
