Description
Technical field
The present invention relates to the displacement pump with delivery chamber, the delivery chamber is connected to pressure and suction connecting portion.Displacement pump is also
With displacement element, the element determines the volume of delivery chamber, and can wherein delivery chamber have smaller volume first position and
Wherein delivery chamber is moved back and forth between having the second place of large volume.Generally, press-in connection portion is via in form of check valve
Pressure valve be connected to delivery chamber, and aspirate connecting portion and be connected to delivery chamber via the suction valve for being also in form of check valve.
Background technology
For delivery media, for example, can be that the displacement element of barrier film is oscillatorily back and forth transported between the first and second positions
It is dynamic.During motion (so-called aspiration stroke is moved) in displacement element from from first position to the second place, the appearance of delivery chamber
Product increases, thus the pressure reduction in delivery chamber.Once the pressure in delivery chamber is decreased below is connected to suction connecting portion
Pressure in aspiration line, suction valve is opened, and medium to be delivered is inhaled into delivery chamber via suction connecting portion.Once row
Amount element moves (that is, so-called pressure stroke motion) from the second place again on the direction of first position, in delivery chamber
Volume reduces, and the pressure rise in delivery chamber.Suction valve closes to prevent medium back flow to be delivered in aspiration line.One
Pressure in denier delivery chamber exceeds the pressure being connected in the pressure line in press-in connection portion, and pressure valve is opened, to cause delivering
Delivery media in room can be pushed into pressure line.
In such displacement pump of membrane pump form described and illustrated in EP1546557B1.
When metering liquid (being specifically similar to the delivery media of the ease gas of such as sodium hypochlorite (NaOCl)), bubble meeting
It is formed at and is connected in the aspiration line of suction connecting portion, and is inhaled into metering head.Bubble is likely to the shape in delivery chamber
Into.This is situation about being frequently encountered after metering process is interrupted for a long time.When suction connecting portion is connected in simplest feelings
Under condition in hose form aspiration line and when terminating at supply container, supply container is changed, (particularly pump is currently running
In the case of) when such situation may occur：Aspiration line is temporarily no longer attached to delivery media and sucks gas.
If vibration delivering pump metering head in there is excessive gas, when metering head intrinsic compressibility due to
Included gas volume and be no longer enough to resist check spring, the intrinsic weight of enclosed member and system pressure to open pressure
Disturbance occurs during valve, in metrological operation.In other words, it may occur however that such situation：If the ratio of the gas in delivery chamber
Example is too high, even if displacement element moves to first position from the second place, the pressure in delivery chamber is also not increased to be enough to beat
Open the pressure valve for being connected to press-in connection portion.The reason for such case is that the compressibility of gas is higher compared to liquid.
Therefore, if displacement element no longer successfully applies sufficiently high pressure to open pressure valve, delivery media will not
It is pumped, that is to say, that required metrological operation can not be carried out.
In order to break away from this malfunction, it is necessary to recover to the offset pressure that is applied at press-in connection portion can
Compressibility.This can be realized by certain program, and by the program, some liquid are introduced into delivery chamber to improve and can press again
Contracting and the ratio of incompressible medium so that the pressure gathered in the motion process of delivery elements can be weighed at press-in connection portion
It is new to obtain offset pressure.
Therefore, for delivering pump shown in EP1546557B1, delivery chamber and another aspect press-in connection portion on the one hand
Between provide additional connecting portion, the connecting portion is opened to allow liquid to be transmitted to delivery chamber from pressure line again off and on
In, thus, gas can simultaneously from delivery chamber effusion, to cause the ratio between compressible gas and incompressible liquid again
Improve, and in the ideal case, the offset pressure at press-in connection portion can be recovered in delivery chamber.
However, the solution is relatively complicated and expensive, because in addition to the by-pass line for adding, it is necessary to provide
Valve and actuation means for activating valve for closing the pipeline.
Therefore, had been proposed that in WO 2013/135681：Pressure valve has non-tight structure, so as to even work as pressure valve
During closing, return flow line interconnects delivery chamber and press-in connection portion, and medium can be transferred in delivery chamber by the return flow line,
And/or gas can be escaped from delivery chamber.
However, the structure the disadvantage is that, delivery characteristics depend on the pressure being connected in the pressure line in press-in connection portion
Power.Particularly, when to resist pressure very high and pumped, the delivering stream in delivery chamber is flow back into by non-tight pressure valve
The amount of body is dramatically increased, so as to reduce measurement efficiency.
The content of the invention
Therefore, in view of background in the prior art for having described, it is an object of the invention to provide such a displacement pump：The appearance
Product pump is self-purging, with simple structure, and is also had in addition even when there is offset pressure high in pressure line
Also the metrology capability of pressure stability.
According to the present invention, the reservoir that the purpose is realized so as to available delivering fluid filling is connected via gas emitting valve
To delivery chamber.
In this respect, term reservoir is used for representing any cavity that the cavity can use delivering fluid filling, and possibly
Separated via valve with delivery chamber and also with both press-in connection portion and suction connecting portion.
In this arrangement, gas emitting valve be designed such that at least to exist in any delivery chamber excessive gas when
Wait, it can be opened or automatically open up during aspiration stroke is moved, thus, delivering fluid is transferred to delivery chamber from reservoir
In, and therefore the pressure in delivery chamber is further up during next pressure stroke is moved.
Even if if the pressure in delivery chamber to rise still be not enough at this moment opens pressure valve, then in next aspiration stroke
During motion, delivering fluid can be transmitted into delivery chamber from reservoir again, to cause the pressure in delivery chamber in pressure stroke
It is further up during motion.This can proceed with, until pressure is fully gathered again in delivery chamber, to open pressure
Valve, so that delivering fluid (possibly together with gas component) is pumped in pressure line.
Therefore, displacement pump preferably of a design such that configuration, i.e. so that delivering fluid can be via suction valve from suction
Connecting portion is delivered in delivery chamber, and without flow through reservoir.Therefore, during aspiration stroke is moved, or even when pressure drop is not enough to
Liquid to be delivered can also be transmitted into delivery chamber when opening suction valve.
In a preferred embodiment, excessively stream coefficient of the gas emitting valve on the direction from reservoir to delivery chamber is less than
The excessively stream coefficient of suction valve.For example, the excessively stream coefficient of gas emitting valve be smaller than the excessively stream coefficient of suction valve 1% or preferably
Even less than the 0.2% of the excessively stream coefficient of suction valve.Excessively stream coefficient is that delivering fluid is capable of achieving on valve of interest
Throughput measure, and be also in principle measuring on effective cross section.According to the present invention, the absolute value of excessively stream coefficient
It is not important consideration, the ratio of the excessively stream coefficient and suction valve of gas emitting valve or the excessively stream coefficient of pressure valve is only.As it
Alternative form, therefore, the effective cross section of gas emitting valve is less than the 1% of the effective cross section of suction valve, and preferably even
Less than the 0.2% of the effective cross section of suction valve.
For example, delivering fluid inflow-rate of water turbine (ml/min) of valve can be defined as the delivering stream in the pressure difference of 1 bar and 25 DEG C
The definition of the excessively stream coefficient under temperature.Inflow-rate of water turbine is defined in the case where valve is opened respectively in this case.
By the corresponding reduction of the excessively stream coefficient of gas emitting valve, or even the gas discharge when not existing gas in delivery chamber
Valve can also be opened, so that the detection to gas flow is not indispensable.It is a certain amount of when gas emitting valve is opened
Delivering fluid outflow reservoir and enter delivery chamber in, this cause gas from delivery chamber discharge.It should, however, be mentioned that
As a result, delivering fluid is also discharged from reservoir, so that reservoir must be again filled with.Additionally, this reducing delivering
Capacity, because less fluid is inhaled into and via in press-in connection portion pump-in pressure pipeline via suction connecting portion.However, due to
The significantly reduction of excessively stream coefficient, pressure capability only minimally reduces.Particularly when excessively stream of the excessively stream coefficient less than suction valve
Coefficient 0.2% when, gas emitting valve also can all the time be opened or may include the choke valve of suitable size.
In another preferred embodiment, gas emitting valve is in the form of throttle non-return valve, and the throttle non-return valve provides permanent
Property throttling connection, and when the pressure in delivery chamber be more than reservoir in pressure when un-throttled connection.Measure proposition, when
When being vented to delivery chamber, reservoir also can again with delivering fluid filling, because now part delivering fluid is pumped to storage
In device.
In a preferred embodiment, under the conditions of un-throttled, the excessively stream coefficient that throttle non-return valve has is less than pressure
The excessively stream coefficient of valve, wherein it is preferred to, the excessively stream coefficient of the gas emitting valve of un-throttled is less than the excessively stream coefficient of pressure valve
15%, particularly preferably less than the 5% of the excessively stream coefficient of pressure valve.
The measure ensures that the only a fraction of of the delivering fluid in delivery chamber is pumped in reservoir, and greater proportion
Delivering fluid is transported in pressure line.
In another preferred embodiment, it is proposed that, gas emitting valve is check-valves, and its pressure in delivery chamber is less than
Opened during pressure in reservoir.Particularly when displacement pump is providing the meter of low pressure, such as environmental pressure only in aspiration line
When being used in amount device, if the pressure in reservoir is more than the pressure in aspiration line, the embodiment with check-valves is
Favourable, because so fluid can be discharged from reservoir during aspiration stroke is moved, even if the pressure in delivery chamber does not decline
Below pressure into aspiration line.
In another particularly preferred embodiment, reservoir is connected to press-in connection portion.In this case, particularly preferably
, gas emitting valve is connected in series with pressure valve, and gas emitting valve is arranged closer to delivery chamber.
In other words, the delivering fluid from delivery chamber pump-in pressure pipeline must first flow through gas emitting valve, Ran Houliu
Excess pressure valve.Therefore reservoir is formed by the connecting pipeline between gas emitting valve on the one hand and another aspect pressure valve.It is accurate
Really say, the advantage of the embodiment is that reservoir is full of automatically again, and this must not in the case of single reservoir
When ground it is manually implemented.For this embodiment, the excessively stream coefficient that gas emitting valve enters reservoir from delivery chamber should be with pressure valve
Excessively stream coefficient it is about consistent.
In another preferred embodiment, reservoir is connected to accumulator.Accumulator or also hydraulic pressure storage device are in pressure
Liquid is stored under power, that is to say, that delivering fluid.
For example, such accumulator can be formed by pressure vessel, and the inner space of the pressure vessel is by movable
Separating member is divided into two rooms, wherein, the gas for serving as pressure reservoir device is kept in one chamber, and delivering fluid is kept
In another room.
According to the present invention, displacement pump can be used in metering device, the metering device have wherein include pressure p2's
Deliver the pressure line of fluid and wherein include pressure p1<p2Delivering fluid aspiration line, wherein, pressure line connection
To press-in connection portion, and aspiration line is connected to suction connecting portion.
It is particularly preferred that the delivering fluid in reservoir is in pressure p3Under, wherein, p1<p3<p2。
The embodiment has advantages below：When there is excessive gas in delivery chamber, and therefore pass through without delivery media
In by pressure valve pump-in pressure pipeline, and even aspiration stroke motion ending at also without other delivering fluid via
When aspiration line and suction valve are inhaled into delivery chamber, in contrast, during aspiration stroke is moved, delivering fluid is via gas
Drain valve is introduced into delivery chamber from reservoir, as a result causes the pressure in delivery chamber to rise in the motion of next pressure stroke.
Brief description of the drawings
Additional advantage of the invention, feature and possible purposes will become aobvious and easy from the following description of preferred embodiment
See.
In the accompanying drawings：
What Fig. 1 showed preferred embodiment shows figure.
Specific embodiment
Fig. 1 roughly shows the metering device with displacement pump.Metering device is used for therefrom including delivering fluid
Fluid pressure p1Delivering fluid aspiration line 1 pump into wherein delivering fluid in Fluid pressure p2Under pressure line 6, wherein,
p2>p1。
Displacement pump has delivery chamber 3, wherein can be moved back and forth between the two positions in the displacement element 11 of iris-diaphragm,
Wherein, in first position shown in broken lines and being represented by reference 4' in figure, delivery chamber has smaller volume；And
In the second place for being shown in solid and being represented by reference 4, delivery chamber has large volume.
When barrier film is from position 4' inflow locations 4, therefore the volume of delivery chamber 3 increases, and under pressure in delivery chamber
Drop.Once the pressure in delivery chamber is less than the pressure p in aspiration line 11, it is arranged between aspiration line 1 and delivery chamber 3 and is in
The suction valve 2 of form of check valve is turned on.
As a result, delivering fluid is transported in delivery chamber 3 from aspiration line 1.
Once the motion inverted orientation of barrier film, that is to say, that once barrier film is moved on the direction of position 4' from position 4,
The volume of delivery chamber 3 is reduced by, and suction valve 2 is closed.
Further rise in pressure in delivery chamber 3, until the pressure p reached or in pressure line 62.In this feelings
Under condition, pressure valve 5 is opened, and is delivered fluid and be transported in pressure line 6 from delivery chamber 3.
Now, according to the present invention, in delivery chamber 3 and also in being provided with reservoir 10 between the pressure valve 5 of form of check valve
With gas emitting valve 7.Reservoir 10 is formed by the connecting pipeline between gas emitting valve 7 and pressure valve 5.Gas emitting valve 7
In the form of throttle non-return valve, that is to say, that it includes throttling connecting portion 9 and check-valves 8.
In normal operating, that is to say, that if do not had in delivery chamber 3 or few gases, gas emitting valve 7 does not influence
The operator scheme of displacement pump.The advantage of the arrangement according to the invention of reservoir and gas emitting valve is only when delivery chamber 3 was included
Become obvious during the gas component of vast scale, this is likely to occur in operation or after long-time is disabled.Due to gas component
Of a relatively high compressibility, more specifically in some cases, this causes barrier film no longer sufficient to the motion of position 4' from position 4
Increased to so that reaching pressure p with by the pressure in delivery chamber 32And the degree that check-valves 5 can be opened.It will be recognised that
In this case, barrier film is moved back and forth between position 4 and 4', but both in the absence of the opening of suction valve 2, also in the absence of pressure valve
5 opening.
However, in this case, according to the present invention, being included in a small amount of delivering fluid in reservoir 10 via choke valve
9 are transmitted back to delivery chamber 3.As a result, the pressure in delivery chamber 3 pressure stroke move at the end of (that is, when barrier film be in position 4'
When) one after the other rise, in check-valves 8 is opened and compressed gas are transferred to reservoir 10.In barrier film returning to position 4
Backhaul it is dynamic in, check-valves 8 is closed, and compressed gas in reservoir 10 only can be expanded to slight degree via choke valve 9.
Because reservoir 10 is now comprising the gas in compressive state, the pressure in delivery chamber 3 will be transported in aspiration stroke
Dynamic period drops to so that other delivering fluid is sucked out the degree of aspiration line 1 via suction valve 2.This also causes in pressure
The increase of the pressure at the end of stroke movement in delivery chamber 3, because now there are more delivering fluids in delivery chamber 3.
If pressure and aspiration stroke motion are repeated, then the pressure in delivery chamber 3 can increase, until gas can quilt
Being compressed to makes it successfully open pressure valve 5 and by the degree in gas entry pressure pipeline.
In principle, gas emitting valve 7 can have with the identical structure described in the A1 of WO 2013/135681,
That is, it can have valve member and valve seat, between valve member and valve seat, or even be there is also for example in closed position
The return flow line formed by groove.Substantially, gas emitting valve represents the check-valves of non-tight.The advantage of described structure exists
In, or even when the operation with high pressure in resisting aspiration line 6, metrology capability is not also reduced, because pressure line 6 is not arranged with gas
Put the permanent contact of valve 7.From the consider relevant with safe practice, this is also advantageous, because in the case of membrane ruptures,
Do not exist permanent connection between metering pipeline 6 and another aspect delivery chamber 3 on the one hand.
