Description
Technical field
The present invention relates to a kind of shell and tube fluid flow straighteners, belong to technical field of fluid delivery；More particularly to by displacement type stream
The shell and tube fluid flow straightener that pressure caused by body conveying equipment and flow pulsation phenomenon are pulsed so as to cause pipeline.
Background technology
Fluid flow straightener be in fluid delivery system eliminate pipeline pulsation common component, fluid flow straightener can stabilize by
Pipeline pulsation phenomenon caused by plunger pump, diaphragm pump isometric(al) pump or compressor.Commonly used in liquids and gases pressure delivery system
In system, effect is for eliminating the pressure fluctuation in pressure piping or gas circuit (fluctuation), loine pressure and flow pulsation being made to stablize
In a certain range.
Common fluid flow straightener type has air type impulse steady flow device, diaphragm type impulse steady flow device, gasbag-type pulse steady
The buffer structure type that stream device and floating piston impulse steady flow device etc. is realized by the inert gas in compression closing vessel.
Since the compression of inert gas is bigger, and its structure is limited, such flow straightener is only applicable to the arteries and veins that ripple frequency is less than 7 hertz
It rushes frequency and eliminates application.If frequency is too high, the motor elements such as diaphragm, air bag or floating piston have little time to respond, and do not have
Eliminate the effect of pulsation.
It is minimum using amount of movement and attract deposit and discharge fluid pulsation kinetic energy the present invention relates to a kind of shell and tube fluid flow straightener
The strong groups of springs of ability attracts deposit and discharges fluid pulsation kinetic energy, and pulsating fluid is made to be transformed into stable fluidised form, slow to reach
Stamping press is pulsed and the effect of flow pulsation.The buffer structure class flow straightener for solving compressed inert is not suitable for dither
The technical barrier of fluid.
The advantage of the invention is that be not only applicable to include two kinds of forms of liquid stream and air-flow fluid, apply also for low frequency and
The different ripple frequency of high frequency；With more it is simple in structure, small, without dynamic mobile parts, without vulnerable part it is non-maintaining and
The features such as easy to connect, is installed.
Invention content
The technical problem to be solved in the present invention is to provide one kind stabilizing low-and high-frequency especially high frequency fluid pressure and flow arteries and veins
Dynamic fluid constant-current stabilizer, the buffer structure type flow straightener to solve existing compressed inert cannot stabilize high-frequency pressure and
The technical issues of flow pulsation.
In order to solve the above technical problem, the present invention provides a kind of shell and tube fluid flow straighteners such as lower structure, including

It is additionally provided with seal groove on head body, closed chamber is made to form reliable sealing.
The ontology is the garden cylindrical barrel body with certain bearing capacity, and ontology is high using metal material bearing capacity, peace
Full effect is good.
The tube sheet is the overcurrent component by having two or a plurality of steel pipe and disk are welded.In order to reduce fluid resistance
Power, the sum of drift diameter area of tube sheet upper tube array should be not less than shell and tube fluid flow straightener and import and export drift diameter area.
The bearing plate is provided with and the quantity such as tubulation on outlet end tube sheet and the disk of multiple circular holes that plugs.
The effect of bearing plate is to accept the pulse energy of outflow fluid in input end tube sheet tubulation and pass to spring adjacent thereto.
The sealing ring uses rubber seal to be placed in a manner of static seal between each connector to prevent fluid from letting out
Leakage.Sealing ring of the present invention is including but not limited to the sealing ring that can play the other structures form effectively sealed.
The operation principle that the present invention stabilizes pressure fluctuation is：Fluid with pressure and flow pulsation passes through end flanges connector
Tubulation in the import and tube sheet of body enters shell and tube fluid flow straightener ontology, and pulsating fluid is made to act directly on bearing plate,
And spring is passed to by bearing plate.Groups of springs Absorbing Fluctuation peak kinetic energy under bearing plate and generate compressive deformation, when one
Pulsation valley fluid in pulsation period comes temporarily, and spring then discharges the kinetic energy that it is attracted deposit and restores deformation.It is this to rely on spring
It attracts deposit and discharges the process of pulse energy so that output pressure is balanced, and plays the role of eliminating pressure fluctuation.
Well known, displacement type conveying equipment for fluid substances is to export fluid by the variation of working chamber volume, at same time
Turn or working in reciprocating mode process in, the instantaneous output flow of displacement type conveying equipment for fluid substances is a variable, if making transient change
Flow is changed into the output fluid of stable state, it is necessary to which the buffer volume that not less than one work period of setting exports total liquid measure is come
Carry out the cushioning balance of flow.The dischargeable capacity of shell and tube fluid flow straightener of the present invention should be not less than conveying equipment for fluid substances
One revolution or two times of the exported flow quantity of working in reciprocating mode process.
It attracts deposit and discharge pulse energy by above-described by spring and stabilize pressure fluctuation, it is larger by setting
Buffer volume carries out the cushioning balance of flow this binomial technical measures, realizes stabilizing for pressure fluctuation and flow pulsation.
The application process of the present invention is that the present invention is serially connected among the outlet end and transfer pipeline of pump or compressor and is given
With fixation, you can play the role of stabilizing and eliminating pressure and flow pulsation.
Shell and tube fluid flow straightener of the present invention including but not limited to shown in the present embodiment with conveying equipment for fluid substances
Thread connecting mode between pipeline, any connection type for implementing to be reliably connected belong to the claim model of the present invention
Farmland.
Advantages and advantages of the invention be to be not only applicable to include two kinds of forms of liquid stream and air-flow fluid, it is also suitable
The ripple frequency different with high frequency for low frequency；With more it is simple in structure, without dynamic mobile parts, without vulnerable part, non-maintaining
And be installed the features such as easy to connect.
