Abstract
A pump enabling a fluid substance to be manually dispensed through a hollow stem (5) projecting from a hole m a ring cap (2) sealedly applied to one end of a pump. The stem can sealedly translate within said hole in the ring cap, which in its turn can be sealedly mounted on the mouth of a container containing the fluid substance to be dispensed.
Description
Technical field
The present invention relates to a kind of improved manual operation pump, be used for a large amount of flowing materials of form such as hollow action bars dispense liquid material, milky substance by pump.Described pump can substance distribute in arbitrary position, simultaneously under regular service conditions, prevent that described bar extends through described hole and also can move between the hole surface in the ring cover of the outer surface of fluid (air, gas or liquid) by bar and adjacent pump.
Background technology
Known have many kinds of manual operation pumps, and in the operating process of pump, a large amount of flowing materials (liquid or emulsion) of the container suction that is mounted thereon from pump are assigned to the outside by the cavity of bar; The bar of hollow extends to pump housing outside by passing the hole that is provided with on the ring cover, and described ring cover forms the part of pump and limits an end of the described pump housing.Term " ring cover " is meant any part or the element that at one end is used for sealing the pump housing, and it allows bar therefrom to pass through.Known pump is installed on the container, and under halted state, pressure and atmospheric pressure in the container are equal substantially.
At US 3,583,605A, US 4,960, the pump of describing in detail among 230A, EP-B-0301615 and the EP-A-1334774 are the examples of the pump of known type, and its instruction is incorporated herein by reference.DE 1728199A has also described the closely similar pump of describing in a kind of and aforementioned four patents of pump.
In order to prevent when extracting fluid by pump from container out and distributing, in container, to form vacuum, passage or hole must be set so that extraneous air can enter in the container in pump, to keep the pressure substantially constant in the container, equal atmospheric pressure substantially.In known technology, air from be arranged on the pump housing passage or pass through from the passage between pump and the pump ring cover mounted thereto, air always passes through between the surface in the hole that the ring cover of hollow rod outer surface and relative pump is provided with, and wherein said bar passes from described hole.
In all aforesaid existing patents, this has all been made explanation clearly, for example in US3583605A among capable, the US 4960230A of the 2nd hurdle 62-67 among capable, the EP-B-0301615 of the 4th hurdle 2-5 among positive number two row on the triplex row reciprocal on the 4th hurdle and the 5th hurdle, the EP-A-1334774 among the capable and DE 1728199A of the 1st hurdle 14-22 the 8th page the 1st section.Passage between the surface in the hole on the ring cover that the outer surface of the hollow stem of pump and bar therefrom pass has brought some problems, one of them problem is to penetrate into the quality that extraneous air in the container can reduce the flowing material that container contents receives, another problem is when container and pump is in horizontal level or during towards the downward press pump of container, and fluid can or leak into the outside of container by described passage seepage.
Can not address these problems by known pump,, in container, form vacuum during with the fluid that prevents from dispense container, to hold a part of and cause pump get clogged (thereby no longer can with) because outside air must enter in the container.
In a different embodiment, treat to distribute so that the flowing material that uses must be contained in the container by distributor, gas-pressurized also is housed in this container, described gas-pressurized is generally used for described material is discharged by distributor under pressure.Distributor plays the effect of manually operated operated pneumatic valve, the unlatching of operated pneumatic valve or close continuous dispensing or the assigned interrupt that causes material respectively.
But also known pump-type distributor is used for from holding the container dispenses fluid material or the gas-pressurized of flowing material and airtight gas-pressurized.As if it is that the structure of these distributors looks very similar with those pumps that are applied in usually on the inner not pressurizing vessel, but in fact the two is obviously different.
For example at US 3,211,346A, US 4,511, among 069A and the GB 1537436A some such pump-type distributors are described, and its instruction is incorporated herein by reference.
These all pump-type distributors all exist some problems, and these problems have brought difficulty for the use of pump-type distributor, and have in fact also hindered the practical application of pump-type distributor.In this respect, these pump-type distributors have the structure similar substantially with pump, but different is that it comprises cup shaped body, and the cavity of this cup shaped body is sealed by ring cover, and ring cover is contained on the vessel port of the container that holds flowing material or gas-pressurized hermetically.Described cup shaped body has chamber with holes, and under the effect of container inner pressure, flowing material rises in the chamber by described hole.Described chamber is by a pistons delimit, and this piston can move hermetically along the inner surface of cup shaped body: the hollow stem that is connected on the piston can move through the hole that is provided with on the ring cover of pump hermetically.Under halted state, piston is promoted by a compression spring that is resisted against on the cup shaped body, and the cavity in the pump rod then passes through closed check valve.
When pump was in halted state, the pressor substance of pump inside acted on the piston, with the sealing of holding pump.Not having to be provided with on the pump housing can be so that flowing material or gas-pressurized can touch hole, hole or the passage of piston face, and wherein said surface is away from the surface towards internal tank.Such result is: carry out the branch timing when operating the pump-type distributor substance, for overcome the compression spring action on piston thrust and the pump cavity in the pressure fluid material act on thrust on the piston, must apply a pressure on bar, the operation of this pressure ratio is used to distribute the required pressure of conventional pump of pressure fluid to want big.Therefore, the internal pressure of the container that pump-type distributor is mounted thereon is big more, and the distribution button of installing at the free end of hollow stem is more little, and is pump operated just difficult more.

Description of drawings
Infinite example in conjunction with the accompanying drawings, by the description to instantiation, pump structure and feature will be clearer among the present invention, wherein:
Fig. 1 is respectively the longitudinal sectional drawing of the preferred embodiment of pump to Fig. 4, and the pump among the figure is in respectively: the initial moment of halted state, allocated phase, the finish time of allocated phase and the centre position that flowing material is drawn into down the pump chamber stage.
The specific embodiment
Except after some details of chatting, Fig. 1 has shown the pump of known type structure to Fig. 4.In order to provide a detailed example, on the structural entity that described pump has with this specification preface in the pump of the existing patent illustrated that illustrates similar or identical, its instruction is combined in herein as a reference: therefore for the sake of simplicity, will no longer describe in detail described pump structure and operation.
Described pump comprises cup shaped body 1, and an end of this cup shaped body 1 has hole 3 by ring cover 2 sealings on the other end.The hollow space that container (not shown in figures) limits is led in hole 3.The ring cover 2 of pump is installed on the vessel port, and adopts any known mode to seal (for example crimping etc.).
The inside of cup shaped body holds annular piston 4, this annular piston 4 can move and seal respectively against above-mentioned surface along the inner surface of cup shaped body and the outer surface of hollow stem 5, described bar can pass the hole that is provided with on the flange 2 and move vertically, and flowing material can be discharged to outside (thereby use) along the cavity of bar, described flowing material before had been sucked into the following pump chamber 8 between the inlet hole 3 (referring to accompanying drawing) of the lower surface that is positioned at piston 4 and pump, following pump chamber 8 holds a check valve of being made up of ball 11, movable between seal receptacle that this check valve can be provided with in the upper end in hole 3 and the stopping element 13, wherein stopping element 13 forms the part of the pump housing.Last pump chamber 9 is limited in the cup shaped body, between piston 4 tops and flange 2, and by being set directly at the hole in the cup shaped body 1 or the external communications of path 10 and cup shaped body.Like this, when pump seal when being installed on the vessel port, the interior pressure of container that the pressure in the last pump chamber 9 are mounted thereon with equaling pump seal all the time.
No matter pump is in user mode or halted state, there is airtight sealing between the surface in the hole on the outer surface of described bar 5 and the relative ring cover 2, described bar extends through described hole and can move, in example shown in the drawings, described sealing can be provided (although the sealing between the hole on described bar and the ring cover can provide in a different manner by packing ring or the O shape ring 12 that rubber or suitable elastic materials are made, the lip limit for example is set simply, this lip limit forms the part of ring cover 2, but it is by the plastic material such as the polyethylene of deformation, polypropylene etc. are made, for the sake of simplicity, the lip limit is not shown).
Main inner characteristic of the present invention is: (no matter pump is in user mode or in halted state) hollow stem 5 is contained in the pilot hole on the ring cover 2 all the time and can moves in described pilot hole under sealing state.In addition, the cup shaped body 1 of pump pump chamber 9 places on the pump housing are provided with hole or path 10.
Therefore, because last pump chamber 9 can not make liquid, air or gas seepage between the hole that the outer surface and the described bar of bar extends through ring cover wherein, and ring cover 2 airtight being installed in hermetically on the vessel port (not shown for simplicity) therefore do not have gas, air or fluid to go out from bar leakage or seepage.Simultaneously, (because path 10 existence) go up in pump chamber 9 pressure all the time with the airtight container that is mounted thereon hermetically of pump in pressure equate.
Therefore, be installed on the vessel port of known cylindrical chamber with supposing pump seal, the other end of this container is by a movable base sealing, during the material that holds in each dispense container, described movable base moves, under any user mode, air all can not penetrate in the container like this, thereby product that container contents is received or material can be by air pollutions or can hardening or exsiccation.
But be installed in the situation on the sack that is subjected to atmospheric extruding deformation at pump, perhaps pump is installed under the situation on the known type container that holds gas-pressurized, and above-mentioned situation is suitable equally.
A kind of especially attractive and favourable application of described pump is: (pump is installed in and makes on this rigid container that internal tank forms airtight sealed space) is equipped with flowing material, half dense material or the milky substance that is mixed with low-boiling point liquid in the rigid container.Described low-boiling point liquid just during 21 ℃ of left and right sides, produces small vapour pressure in regular service conditions.
Described low-boiling point liquid is to have the 1.00kg/cm of being lower than in the time of 15 ℃
2Saturated vapour pressure, and in the time of 37.80 ℃, have the 2.8kg/cm of being lower than
2The fluid of saturated vapour pressure.
Described low-boiling point liquid be boiling point+15 ℃ and+85 ℃ between and produce the fluid chemistry material of the pressure that is about 1 atmospheric pressure (about 760 millimetress of mercury).
Preferred low-boiling point liquid is chosen from following material composition: isopentane, isohexane, pentane, n-hexane, carrene, a chloropropane, 1-1-dichloroethanes, Sec-Butyl Chloride, Arcton 11 CFC 11, trichorotrifluoroethane CFC 113, ether, methylene-dimethyl ether, dimethoxymethane and acetone.
Under the sort of situation, when pump distributing fluids mixture, the low-boiling point liquid that exists in the container evaporates from its liquid phase mixture, and recovers the desired pressure (a little higher than atmospheric pressure) in the container, thereby avoids forming the vacuum that obstruction is distributed continuously from rigid container.
A feature that is even more important of the described pump that is described with reference to the drawings is: when halted state, the following pump chamber 8 of pump and the pressure in the last pump chamber 9 equates, therefore acting on the upper surface of piston 4 is identical with pressure on the lower surface.This shows, for (for simplicity by the cavity dispenses fluid material in the bar, the button of any known type is installed on the free end of pump outside of bar), it is applied to the thrust that pressure on the bar (referring to accompanying drawing 1 to accompanying drawing 3) only need overcome two springs 20 and 30, and needing compression to collect in the pump chamber 8 down with the flowing material that holds makes the sealing lip 40 on the piston 4 separate with corresponding seal receptacle in the axle collar 50, the described axle collar and bar 5 are rigidly connected, and therefore form the part of bar 5.Therefore, the operation of pump does not just need very big power, and power that it is required and the pump that is installed on the fluid material container in known non-tight mode divide the required power of timing to equate.
Through the feed liquor stage, pump turns back to the stop position (see figure 1) from the position that arrives the operational stroke end, can only under spring thrust, carry out reposefully, and can not resemble US 3,211,346A, US 4,511, the pump-type distributor among 069A and the GB 1537436A exists very large difficulty like that.In the described pump-type distributor, the piston of each chamber top is provided with the last pump chamber (promptly not existing as the indicated hole of Reference numeral in the accompanying drawing 10) of airtight sealing.
Pump of the present invention is particularly useful for being distributed under 54.4 ℃, produces less than 2.8kg/cm
