Abstract
The utility model disclose an air-cushion elbow which is designed for solving the problem that a 90-degree elbow for an emptying pipeline in natural gas production is easy to be leaky. The air-cushion elbow comprises a tee joint, a straight pipe and a cap, one end of a straight pipe section of the tee joint is connected with the straight pipe, the other end of the straight pipe section of the tee joint is connected with a gas inlet pipeline, a bending pipe section of the tee joint is connected with an emptying outlet, and the other end of the straight pipe is connected with the cap. According to the design concept of 'forming an air cushion by fluid', fluid gathers at the joint of the straight pipe and the cap during flowing so as to form the air cushion. Scouring effects of solid particles are blocked by reacting force of the air cushion when subsequent fluid flows through the elbow, walls of the elbow cannot be impacted directly, and accordingly, safety of the elbow is guaranteed. The air-cushion elbow can effectively resist impact of high-speed fluid, is safe and reliable to use, simple in structure, easy to process, long in service life, low in cost and wide in applicable range.
Description
Technical field
The utility model relates to a kind of air cushion elbow, belongs to the gas production field of engineering technology.
Background technique
The pipe transporting fluid is used 90 ° of camber elbows always when the adjustment direction, its shortcoming is when fluid is flowed through elbow; Because washing away pipeline, action of centrifugal force, the solid phase particles in the high-velocity fluid be prone to cause the elbow thorn to leak, particularly in gas industry; Often pierce through emptying blowdown line elbow, causes stopping production, and serious meeting causes security incident; Though many times adopted the thickening elbow, can't tackle the problem at its root.
Summary of the invention
The purpose of the utility model is to provide a kind of air cushion elbow, and it can solve, and 90 ° of camber elbows of blow-down pipe are prone to the problem that thorn leaks, safe and reliable easy processing, long service life in the gas production process.
The concrete technological scheme of the utility model is following:
The air cushion elbow is made up of threeway, straight tube and pipe cap, and three-way straight pipe Duan Yiduan connects straight tube, and the other end connects to come air pipe, and the threeway bend loss connects the emptying outlet.The straight tube the other end connects pipe cap.
The utility model air cushion elbow adopts and to let the mentality of designing of fluid " self forms air cushion ", and promptly fluid accumulates in straight tube and pipe emits the place in flow process; Form by " air cushion "; When follow-up fluid passes through elbow, receive reaction force from " air cushion ", the souring of solid phase particles is received and is stopped; Can not directly impact the elbow tube wall, thereby guarantee the safety of elbow.This air cushion elbow be highly resistant to high velocity fluid strikes, safe and reliable, simple in structure, be prone to processing, the life-span is long, price is low and applied widely.
Description of drawings
Accompanying drawing is an air cushion elbow structure schematic representation.
Embodiment
Embodiment to the utility model further specifies with reference to accompanying drawing:
Embodiment:
90 ° of camber air cushion elbows are made up of threeway 1, straight tube 2 and pipe cap 3, threeway 1 straight length one end welding straight tube, and the other end welds air pipe, threeway bend loss welding emptying outlet.Straight tube the other end welding semicircle hat pipe cap.Both equal tee of threeway 1 wherein, also reducing tee is as long as match with connecting line.
