Description
Technical field
The utility model category technical field of fluid delivery, it is related to and a kind of is arranged on conveying containing solid class lotion and slurry material
The port of export of displacement pump, for stabilizing the pulsation flow straightener of fluid pulsation；Be related to one kind simultaneously includes various liquid installed in conveying
Body, gas, biphase gas and liquid flow and solid-liquid two-phase flow displacement pump the port of export, include liquid, gas, solid-liquid two for stabilizing
The mutually pulsation flow straightener of stream and the various fluid pulsations such as Ben-Hur type fluid or non newtonian structural fluid.
Background technology
In fields such as mine, oil exploitation, architectural engineering and environmental protection, general use includes the work such as piston, plunger, barrier film
Part in the pump housing reciprocating or gyration displacement pump to lotion, Paste-like body and slurry (such as concrete, fracturing slurries,
The Ben-Hur type fluid or non-such as coal slime, carbide slurry, red mud, sludge, kitchen garbage, water-coal-slurry, concentrate slurry, filling slurry and Tailings Slurry
Newton structural fluid etc.) implement remote high-pressure delivery, but because such displacement pump is all by making several work in the pump housing
The volume cyclically-varying of chamber, and fluid is alternately sucked and discharges, the change of volume will necessarily cause institute's trandfer fluid
Flow and pressure fluctuation.Caused fluid pulsation when displacement type conveying equipment works, fluid can be not only set to produce the pressure of moment
Power and mass flow discrepancy weighing apparatus, while can also cause vibrations and the impact wear of conveyance conduit, and then accelerate pipeline and its connecting portion
Failure damage.
To solve this problem, the technical field also has some diaphragm type surge tanks, flexible pipe buffer and piston-type buffer
It is applied Deng device in engineering practice, but because barrier film and flexible pipe are difficult to the flexural deformation of bearing high frequency time, causes to make
The defects of with short life, replacement cost height and being difficult to bear high pressure；Especially above-mentioned diaphragm type surge tank, flexible pipe buffer and work
The devices such as plunger type buffer are all that side is put on the transfer pipeline of pump discharge, and this mounting means both destroys circular channel
Integrality, the flowing to non newtonian structural type fluid causes certain resistance, while also easily blocks and delay into the above-mentioned type
The passage of flushing device, cause to reduce the effect for eliminating pulsation or failure.
In addition, the pulsation damper such as diaphragm type surge tank, flexible pipe buffer and piston-type buffer is can by filling
The compression Absorbing Fluctuation energy of compressed inert, it is only applicable to the conveying equipment for fluid substances application that ripple frequency is less than 7Hz.
Because if frequency is too high, diaphragm, air bag or piston have little time to respond, and do not have the effect for eliminating pulsation.So above-mentioned pulsation
The pulsation that cancellation element is not suitable for high frequency time yet eliminates.
3rd, hydraulic pump, water conservancy conveying and gas transportation facilities for displacement type, shadow caused by order to eliminate pulsation
Ring, typically also configure the high-pressure buffering pot with suitable volume be used for eliminate pulsation, not only cause equipment volume to increase, also increase
Unit cost.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiency of above-mentioned various conventional buffer devices, there is provided Yi Zhongjie
Structure is simple, small volume, in light weight and bear pressure height, is applicable to various liquid, gas, solid-liquid two-phase flow and Ben-Hur type fluid
Or the various fluids such as non newtonian structural fluid and the through-type pulsation flow straightener of more extensive frequency system.
In order to solve the above technical problems, the utility model provides the through-type pulsation flow straightener of following structure, including
The elements such as body, sealing ring, connecting pipe hoop, flow tube, high elastic damping body and the pipeline connector at body both ends are formed, each member
Part combines composition the utility model in the following manner：High elastic damping body loads body after being linked in excessively stream tube outer surface
Inner chamber, connection is implemented to body and pipeline connector with connecting pipe hoop, sealing ring is also equipped between body and pipeline connector
To ensure effective sealing.
Body described in the utility model is the closure cylinder that can bear Fluid pressure.
The flow tube is can to pass through fluid, and the tubular barrel of multiple apertures is provided with tube wall, described
Flow tube with certain rigidity and erosion resistant metal material, silk screen or ceramics by being made.
The high elastic damping body is the elastomeric material being filled between body and flow tube, the high elastic damping body by
High elastic rubber or Elastic silk screen are made.
The pipeline connector at described body both ends, one end are connected with the outlet of fluid conveying machine, the other end with it is defeated
Pipeline is sent to be connected.In view of the diversity of connected mode, pipeline connector is including but not limited to shown in the utility model accompanying drawing
Type of attachment, a variety of effective other types of attachment of such as screw thread, flange.
Particularly, it is described in the utility model it is through-type pulsation flow straightener also include be integrated in fluid conveying machine device it
It is interior, the functional module of the fluid conveying machine device eliminated as pulsation.
Remarkable result of the present utility model is achieved by the following technical solution：Flow through the through-type pulsation flow straightener
The fluid with pulse energy of entrance point, is acted on high elastic damping body by the aperture on flow tube.The peak stream of fluid
Kinetic energy is filled in intrinsic high elastic damping body by the aperture compressing on flow tube, is run through absorbing the kinetic energy and occurring
Elastic deformation；In pulsation peak stream by the way that afterwards, high elastic damping body recovers its deformation and the energy absorbed is released to pulsation paddy
Stream.This process of the peak energy of flow and release stored energy to pulsation paddy stream of pulsing of being attracted deposit by high elastic damping body so that arteries and veins
The peak valley pressure of dynamic fluid is balanced, and serves the beneficial effect for stabilizing fluid pulsation.
