Each exhaust port 7 as shown in FIG. 1 to 3, is also as the parts of the valve opening performance function of valve seat 10b, is formed on the diapire of clack box 10a,, at pump chamber 3 inner openings, through discharging side safety check 10, with the end, upstream of drain passageway 11, is connected.
In addition, although with regard in bellows 4 component parts such as pump such as grade with regard to the parts of liquor charging fluid contact, according to the selected appropriate materials such as proterties of this fluid, the resistant material by fluorine type resins such as teflon forms in this embodiment.
although above-mentioned structure is with known compound identical toward double acting pump, the discharge operation of being undertaken by the first pump 1A and by the discharge operation that the second pump 1B carries out, alternately being carried out continuously, can be from the suction part of liquor charging pipeline to discharge section liquor charging continuously, but, to the above-mentioned first and second pump 1A, 1B is studied, so that according to the present invention, prevent effectively each suction side safety check 8 and the work bad (gas lock) of discharging side safety check 10 by further forming in the following manner, well to Ozone Water, aquae hydrogenii dioxidis etc. have the liquid of foaminess, with high temperature, high pressure, cavitations etc. have been thereby the liquid that contains bubble carries out liquor charging.
First, are connected with drain passageway with the upper area with each pump chamber 3 and directly are communicated with connection as Fig. 1～as shown in Figure 5 by the pore path 14 that cross section is the toroidal in small footpath, make liquid this pump chamber 3 in 11 trace flow out from pore path 14 to drain passageway discharging operation, and the mode of the micro-inflow of the upper area of the liquid inhalation process makes drain passageway 11 in from pore path 14 to this pump chamber 3 forms.
Namely, each pore path 14 as shown in Figure 4, by being to form wall 2a at path to tighten the first component that bottom tube-like is arranged 15 that the axial direction (substantially horizontal) at bellows 4 connects its, the chimeric second component 16 that is fastened with bottom tube-like in the end of this first component 15, base end part at the 3rd parts 17 of these second component 16 chimeric tightening cylindricals, make via hole 15a, the 16a, the 17a that are formed on each parts 15,16,17 be communicated with and be formed in the horizontal direction.Be formed on the end of the via hole 15a on first component 15 at drain passageway 11 inner openings, the via hole 17a of this via hole 15a and the 3rd parts 17 is communicated with through the via hole 16a of second component 16.
The 3rd parts 17 are with the upper side of bellows 4, partly not interfere, and the state that approaches with it is flatly outstanding to the upper area in pump chamber 3 from path formation wall 2a.The overhang of the 3rd parts 17 as shown in FIG. 1 to 3, in the front end of the 3rd parts 17 is not interfered with its diapire 4c when bellows 4 carries out expanding-contracting action scope, is set longly as far as possible.In addition, first and second component 15, an end face of 16 and the path end face (end face of pump chamber side) that forms wall 2a be flush, be exposed to the end of first component 15 of drain passageway 11 and the telescoping part that path forms wall 2a and sealed by O shape ring 15b.
Therefore, although in inhalation process, exhaust port 7 seals by discharging side safety check 10, still, and the liquid 3 interior inflows from pore path 14 to pump chamber (Fig. 2 in the Fig. 1 the first pump 1A and state shown in Figure 4 or the second pump 1B and state shown in Figure 3) in drain passageway 11.At this moment, due to the opening portion of pore path 14, namely, nozzle bore 14a is to the upper area opening in pump chamber 3, so, from each nozzle bore 14a to this upper area ejection liquid.And in inhalation process, the bubble of pump chamber 3 interior generations swims to the upper area in pump chamber 3, and the bubble that produce new with the progress that is accompanied by inhalation process is fit also grows up.But, due to as described above, the upper areas ejection liquid from each nozzle bore 14a to pump chamber in 3, so the growth of bubble is stoped by its discharging jet, in addition, large bubble is divided imperceptibly.Set its opening for as described above at the annular recessed portion 4d of the terminal stage at least of inhalation process and the perisporium inner peripheral surface that is formed on bellows 4 in opposite directions by the configuration with each nozzle bore 14a, and can more effectively carry out growth prevention and even the splitting action of such bubble.
And, if although from inhalation process, enter the discharge operation, the liquid in pump chamber 3 is discharged to discharging stream 11 through discharging side safety check 10 from exhaust port 7, but the liquid of the upper area in pump chamber 3 flows out (Fig. 1 in Fig. 2 first pump 1A and shown in Figure 3 state or second pump 1B and shown in Figure 4 state) through pore path 14 to drain passageway 11 trace from each nozzle bore 14a simultaneously.At this moment, bubble in upper area in pump chamber 3 is owing to being stoped and growing up by the discharging jet from each nozzle bore 14a at inhalation process as described above, and division imperceptibly, so, be accompanied by from pore path 14 to drain passageway 11 efflux, to drain passageway 11, discharge.
Therefore, even in the situation that the liquor charging fluid is liquid with foaminess, contains alveolate liquid, do not exist because of inhalation process yet and discharge operation repeatedly, the situation that bubble is looked large at the interior one-tenth of pump chamber 3, the generation of such gas lock phenomenon of setting forth in the time of can avoiding starting in advance, bring into play good liquor charging function.In addition, the internal diameter of pore path 14 in inhalation process 3 the influx from pore path 14 to pump chamber so that discharge operation from pore path 14 to the discharge of discharging stream 11 with intake from suction port 6 and even from the discharge capacity of exhaust port 7, be in a ratio of extremely trace, and the scope that can not impact the pumping function of this pump 1A, 1B (quantitative etc.), correspondingly appropriately set with pump condition (proterties of liquid etc.), stop splitting function and the bubble discharge function outside pump chamber in order to bring into play well the growth of above-mentioned bubble.
The second, make each suction port 6 picture Fig. 1～Fig. 3 and as shown in Figure 5, interior to its upper area opening at least at pump chamber 3, growth prevention, the splitting action of seeking more effectively to carry out the bubble in inhalation process.
Namely, each suction port 6 as shown in Figure 5, the direction that is branched to scalable direction at pump chamber 3 (as the substantially horizontal of the flexible direction of bellows 4) quadrature is a plurality of suction 6a, 6b, 6c, the 6d of opening radially.Namely, the opening portion to pump chamber 3 of each suction port 6 comprises to the suction 6a of the upper area opening in pump chamber 3, is branched at the Zhou Fangxiang of clack box 8a four suction 6a, the 6b, 6c, the 6d that separate uniformly-spaced (90 degree interval).
Therefore, in inhalation process, the liquid of 3 interior suctions comprises that from each suction 6a, 6b, 6c, 6d the upper area of pump chamber 3 is to four direction ejection (Fig. 2 in the Fig. 1 the first pump 1A and state shown in Figure 5 or the second pump 1B and state shown in Figure 3) from suction port 6 to pump chamber, accordingly, liquid in pump chamber 3 is stirred, stop growth, the gigantism of bubble, perhaps bubble is divided imperceptibly.Its result is, more effectively discharges passing through in operation and follows from pore path 14 to drain passageway the discharge of the bubble that 11 efflux carries out.
In addition, relevant liquid of the present invention is not limited to aforesaid way with the volume type pump structure, can improve rightly, change in the scope that does not break away from basic principle of the present invention.
For example, the pore path also can be made does not have said nozzle hole 14a, only connects path and forms the path of wall 2a.Namely, in the content of Fig. 6～shown in Figure 8, form that wall 2a is formed on that substantially horizontal connects it and with the pore path 18 of the connection of the upper area drain passageway 11 and pump chamber 3 at path.This pore path 18 is to make cross section be pore path with the toroidal in above-mentioned pore path 14 identical footpaths., because Fig. 6～pump shown in Figure 8 is except the structure of above-mentioned pore path 18, be the pump of same configuration with the pump of Fig. 1～shown in Figure 5, so to the mark of the structure beyond pore path 18 symbol identical with Fig. 1～Fig. 5, the description thereof will be omitted.
In addition, although make the structure that makes pore path 14,18 always become open state in above-mentioned example, but, also can look like Fig. 9～as shown in Figure 12, set and allow from pump chamber 3 to drain passageway 11 flow of fluid at the pore path, and stop safety check to its reciprocal flow of fluid.Although the pump of Fig. 9～shown in Figure 12 is as setting forth below, to have set to allow from pump chamber 3 to drain passageway 11 flow of fluid on pore path 19, and stop to the pump of the safety check 20 of its reciprocal flow of fluid, but, except this point, be to be the pump of same configuration with the pump of Fig. 1～shown in Figure 5, therefore, by the structure mark symbol identical with Fig. 1～Fig. 5 to beyond pore path 19 and safety check 20, the description thereof will be omitted.
Namely, in Fig. 9 and the first and second pump 1A, 1B shown in Figure 10, the pump side end face that forms wall 2a at path is formed on the recess 2c of the upper area opening in pump chamber 3, and the part that is formed with recess 2c that forms in wall 2a at path is formed on substantially horizontal with its perforation and with the pore path 19 of the connection of the upper area in drain passageway 11 and pump chamber 3, at the recess 2c of the pump chamber side end that forms this pore path 19, sets safety check 20.Pore path 19 is that cross section is the pore path with the toroidal in above-mentioned pore path 14,18 identical footpaths.
Then, due in discharging operation, spool 23 is positioned at out valve position, valve opening 21a is opened, so, same with above-mentioned situation, the liquid in the upper area in pump chamber 3 flows out (Fig. 9 second pump 1B and shown in Figure 10 state) through pore path 19 to drain passageway 11 trace from valve opening 21a, each semi-circular groove 21c and each circular port 22a, 22b.At this moment, the bubble in the upper area in pump chamber 3 is followed from pore path 19 to drain passageway 11 efflux, to drain passageway 11, is discharged from.
And if from discharging operation, enter inhalation process, spool 23 is positioned at and closes valve position, and valve opening 21a is closed, and pump chamber 3 and drain passageway 11 are cut off by the connection that pore path 19 carries out.Namely, carry out the inhalation process identical with the situation that pore path 19 is not set.
Then, because even the liquor charging fluid is liquid with foaminess, in the situation that contains alveolate liquid, due in inhalation process once, the amount of the bubble of the interior generation of pump chamber 3 or intrusion is small and its bubble is also little, so, at every turn from inhalation process, enter and discharge operation and all as described above bubble is excluded together with discharge liquid from pore path 19, accordingly, do not exist bubble growths in pump chamber 3 to obtain large situation.Therefore, although in the pump of Fig. 9～shown in Figure 12, pore path 19 is constituted safety check 20 is set thereon, only open in the discharge operation, in inhalation process sealing, still, the pump that can become open state always with pore path 14,18 as above-mentioned is same, avoid in advance the generation of gas lock phenomenon, bring into play good liquor charging function.In addition, owing to making each suction port 6 same with the situation in said pump, in pump chamber 3 at least to its upper area opening, so, can also effectively carry out growth prevention, the splitting action of bubble in inhalation process.
In addition, due to when the suction stroke, liquid 3 does not flow into from drain passageway 11 to pump chamber, so, can access stable discharge capacity, and can avoid the gas lock phenomenon, and obtain effectively the quantitative of pump.
In addition, safety check 20 can as shown in figure 13, not be the pump chamber side that is provided in pore path 19, but be provided in the drain passageway side yet.Namely, in pump shown in Figure 13, it is flush with the drain passageway side end face that path forms wall 2a that clack box 21,22 is configured to its lid 22.In this case, extend the front end of clack box main body 21, making the front-end face of this prolongation and the pump chamber side end face that path forms wall 2a is flush, at the pore path 19 of this prolongation formation upper area opening in 3 from valve opening 21a to pump chamber.In the situation that form by this way, also can bring into play the action effect identical with the pump of Fig. 9～shown in Figure 12.
