Abstract
The utility model, which belongs to the technical field of liquid inlet and outlet valves switches, discloses a liquid quantitative controlling device. The utility model is characterized in that the liquid quantitative controlling device comprises an inner plunger barrel and an outer plunger barrel, wherein, the inner plunger barrel is sheathed in the outer plunger barrel; the lateral side of the outer plunger barrel is provided with openings, through which liquid flows in and is discharged, a ballast weight or a float, an end cap for the outer plunger barrel, a connecting rod which is connected with the lateral wall of the inner plunger barrel and the ballast weight or the float through end caps. The utility model solves the problem that liquid can be easily lost because of being controlled to flow in and discharge by a ball valve or a rubber valve or other control devices are complicated in structure, can be widely used on various containers, which need to have liquid flow in or discharge from the bottom of the containers, and has the advantages of simple structure, operational safety and convenience.
Description
The utility model belongs to the valve switch technical field that controlling liquid flows to, discharges, and relates to liquid flux quantitative control device specifically.
At present, the switches that adopt level sensor to come opertaing device are discharged in flowing to of some liquid in containers more, and these equipment exist the defective of complex structure, easy break-down, maintenance difficult mostly.And some civilian need flow to from the bottom, the container of discharged liquid, as the water tank of train, the water tank in the lavatory etc. then be advance, the inboard of freeing port fixes a ball valve or sheet rubber, advance during last water, draining is washed open or draw back ball valve or sheet rubber, stop into, depended on pressure makes that ball valve or sheet rubber will advance, freeing port blocks during draining.Though this advances, the structure of freeing port is simple, exist fragile and easily run, emit, the defective at drench, leakage waste water source, and can not to advance, draining realizes quantitatively controlling.
The purpose of this utility model just provides a kind of simple in structure, and the may command liquid quantitative flows to control device.
Another purpose of the present utility model just provides the quantitative control device that the liquid in a kind of may command container simple in structure is discharged.
The structure that the liquid of first purpose of realization the utility model flows to quantitative control device includes two inside and outside plunger barrels that can slide relatively that are nested, the bottom of outer plunger tube is tightly connected with the mouth that flows to of container, its sidewall has run-in-hole, upper port is fixed an end cap that has eyelet, passes eyelet on the end cap with cursory fixedly connected with the fixedly connected connecting rod of the sidewall of inner plunger tube.
Its main additional technical feature is: closely be nested between the barrel of two plunger barrels that are nested; Run-in-hole on the sidewall is positioned at first end of plunger barrel; Connecting rod can be 1-4; Be fixed with sealing shroud on the end cap eyelet; The length of inner plunger tube is greater than the height of outer plunger tube end cap to the run-in-hole base.
Realize that a kind of liquid quantitative control device that second purpose of the utility model proposes includes two inside and outside plunger barrels that are nested, the low port that wherein has the outer plunger tube of exhaust opening on the sidewall is tightly connected with the liquid outlet of container, its upper port connects with the same weight of the fixedly connected eyelet of connecting rod on described end cap of inner plunger tube sidewall by having the end cap seal of eyelet.
Its additional technical feature is: closely be nested between the barrel of two plunger barrels that are nested; Connecting rod can be 1-4; The length of inner plunger tube is greater than the height of outer plunger tube base to the edge, last hole of exhaust opening.
The liquid quantitative that the utility model proposes flows to, discharge control apparatus is compared with prior art, because tube plug that it only is nested and can slides relatively by two and cursory or counterweight are formed, has characteristics simple in structure, easy to use.
Below in conjunction with drawings and Examples to the structure of the liquid quantitative control device that the utility model proposes and the detailed description of use principle:
Fig. 1: liquid quantitative flows to the structural drawing of control device;
Fig. 2: the structural drawing of liquid quantitative discharge control apparatus.
To flow to the structure of control device be that the outer plunger cylinder 8 of band edge lid 1 is fixedly connected with the water inlet 7 of container 12 to liquid quantitative as shown in Figure 1, have inlet opening 5 in the side of its barrel, be set in and be fixed with 1-3 connecting rod 3 on the top barrel of the inner plunger cylinder 6 in the outer plunger cylinder and connect with cursory 4 by the eyelet of opening on end cap 2.In this structure, the barrel of inside and outside plunger cylinder can slide relatively, but sealing relatively between the two, connecting rod 3 is with then sealing by O-ring seal 11 between the eyelet 2.Before water tank (container 12) was gone up water, inner plunger cylinder 6 was because the effect of self gravitation then is in position as shown in the figure, and promptly the inner plunger cylinder is communicated with water tank by inlet opening 5.On the water tank during water, water enters water tank through water inlet 7 by inner plunger cylinder and upper port, inlet opening, when water level rises to cursory the contact, because buoyancy is cursory to raise with water level, and drive move on the inner plunger cylinder its inwall distolateral be higher than behind the inlet opening since the length of inner plunger cylinder greater than the distance of base, inlet opening to the cylinder end cap, therefore cut off the water inlet of water inlet, water tank stops to go up water.The height of the water level in the water tank can be realized by adjusting cursory upper-lower position.
Be illustrated in figure 2 as the structure of liquid quantitative discharge control apparatus.This structure is basic identical with flowing to control device, it is fixedly connected with the freeing port 9 of container to be that 1 and the lower side its barrel of band edge lid has an outer plunger cylinder 8 of apopore (the apopore here is the inlet opening 5 of inlet control device), inner plunger cylinder 6 is set in the outer plunger cylinder 8, and fixedly connected by the same counterweight of the eyelet on the end cap 12 10 by connecting rod 3.During draining, ballast 10 is mentioned, be about to the upside that the inner plunger cylinder is carried the apopore to the outer plunger cylinder side wall, the liquid in the water tank (water) does not have the direction of arrow to flow out from outer plunger cylinder and freeing port through apopore.After reaching discharge capacity, put down counterweight through control device, then the inner plunger cylinder glides and by its sidewall apopore and freeing port is cut off.Because the length of inner plunger cylinder is greater than the height of outer plunger cylinder base to the top of freeing port, thereby reach the purpose that stops draining.
