Abstract
A kind of compound constant-current stabilizer of pulsating liquid conveying, including flow in pipes, flow in pipes are connect with primary damper, and diaphragm is equipped in primary damper, and primary damper is equipped with second level damper and check-valves, and second level damper is arranged oppositely with flow in pipes.A kind of pulsating liquid provided by the utility model conveys compound constant-current stabilizer; using two-stage damper; compound abatement fluid pulsation; guarantee that the liquid outpoured is steady; and there is releasing pressure automatically defencive function after pipeline superpressure, it is able to achieve the current stabilization conveying of liquid preparation, and not only in this way convenient for the accurate monitoring of the instrument such as flowmeter; pipeline vibration can also be reduced or remitted, pipe valve service life is increased.
Description
Technical field:
The utility model belongs to liquid preparation note control technical field, and it is compound steady to be primarily related to a kind of pulsating liquid conveying
Flow device.
Background technique:
In liquid preparation by the way that in metering pump transmission process, sucking, discharge of the meeting with metering pump lead to the liquid of conveying
There is periodic pulsation, this not only will cause the vibration of pipe-line system, and can be to the accurate of the measuring instruments such as subsequent flowmeter
Monitoring brings error.The mode taken at present is that a pulsation damper is arranged on outpouring pipeline bypass, can be played in this way
Certain effect, but it is ineffective, 70% pulsating quantity can only be generally eliminated, and maloperation pipeline overpressure protection work can not be played
With.
Summary of the invention:
Above-mentioned in order to overcome the shortcomings of, the present invention provides a kind of pulsating liquids to convey compound constant-current stabilizer.
The technical solution adopted by the present invention to solve the technical problems:
A kind of compound constant-current stabilizer of pulsating liquid conveying, including flow in pipes, flow in pipes are connect with primary damper, just
Diaphragm is equipped in grade damper, primary damper is equipped with second level damper and check-valves, second level damper and flow in pipes pair
To setting.
Overflow valve is additionally provided on the primary damper, overflow valve is the spring loaded safety valve of vertical installation.
Sampling valve is additionally provided on the primary damper.
Pressure monitoring table is additionally provided on the primary damper.
The check-valves, second level damper, pressure monitoring table, overflow valve, sampling valve and flow in pipes are respectively positioned on diaphragm
Side.
Due to the adoption of the technical scheme as described above, the present invention has the following advantages:
A kind of pulsating liquid provided by the utility model conveys compound constant-current stabilizer, using two-stage damper, compound abatement
Fluid pulsation guarantees that the liquid outpoured is steady, and has releasing pressure automatically defencive function after pipeline superpressure, is not only able to achieve in this way
The current stabilization of liquid preparation conveys, and convenient for the accurate monitoring of the instrument such as flowmeter, can also reduce or remit pipeline vibration, and increasing pipe valve makes
Use the service life.
Detailed description of the invention:
Fig. 1 is the overall structure diagram of the utility model；
In figure: 1, primary damper；2, second level damper；3, pressure monitoring table；4, overflow valve；5, check-valves；6, it samples
Valve；7, diaphragm；8, flow in pipes.
Specific embodiment:
The present invention can be explained in more detail by following example, the open purpose of the present invention is intended to protect model of the present invention
All interior changes and improvements are enclosed, the invention is not limited to the following examples；
A kind of pulsating liquid in conjunction with described in attached drawing conveys compound constant-current stabilizer, including flow in pipes 8, flow in pipes 8 with
Primary damper 1 connects, and is equipped with diaphragm 7 in primary damper 1, it is two sections that primary damper 1 is divided to by diaphragm 7, wherein in one section
It is sealed with air, this partial air is fashionable in pulsatile liquid flow, can play steady flow result, and primary damper 1 is equipped with second level
Damper 2 and check-valves 5, second level damper 2 are arranged oppositely with flow in pipes 8, are arranged oppositely and are enabled to fluctuate biggish arteries and veins
After hydrodynamic body enters primary 1 preliminarily stabilised of damper, just enters second level damper 2, pulsatile liquid flow can be reduced as far as possible
Enter the obstruction of second level damper 2.
Overflow valve 4 is additionally provided on the primary damper 1, overflow valve 4 is the spring loaded safety valve of vertical installation, it is ensured that
It can releasing pressure automatically when pipe-line system superpressure.
Sampling valve 6 is additionally provided on the primary damper 1.
Pressure monitoring table 3 is additionally provided on the primary damper 1.
The check-valves 5, second level damper 2, pressure monitoring table 3, overflow valve 4, sampling valve 6 and flow in pipes 8 are respectively positioned on
The side of diaphragm 7.
The utility model is installed on metering pump discharge, and primary damper 1 is made of double-seal head stainless steel tube, for preliminary
Eliminate pulsation and confluence.Second level damper 2 uses diaphragm type structure, can eliminate 95% by pulsation after it.Pressure monitoring table 3 is used
Pressure is outpoured in measurement and display liquid.Overflow valve 4 uses spring loaded safety valve, when loine pressure is more than setting pressure, it
Meeting releasing pressure automatically is to metering pump inlet, to protect pipe-line system.Check-valves 5 outpours fluid for control and prevents reverse flow of fluids.
The pulsating fluid that metering pump outpours initially enters primary damper 1 and eliminates part pulsation, then passes through second level again and hinders
Buddhist nun's device 2 further eliminates pulsation, and fluid more stable so just passes through check-valves 5 and outpours in process system, in this process
Middle pressure monitoring table 3 monitors and indicates at any time the pressure condition of fluid, such as needs to sample or long-term when not having to need condensate drain, can be with
It opens on-line sampling valve 6 and sampling analysis or condensate drain operation is carried out to medicament, overflow valve 4 is for protecting pipe-line system, when pipeline system
It can releasing pressure automatically when superpressure of uniting.
Not stating part in the above content carefully is the prior art, therefore does not run business into particular one and state.
