Embodiment one

The present embodiment one provides fluid pressure differential device 100.

Referring to Fig. 1, the fluid pressure differential device 100 includes fluid reservoir 110 and outlet pipe 120.

Wherein, fluid reservoir 110 is for storing liquid, and air inlet 111 and infusion port 112 are equipped on fluid reservoir 110.Go out Liquid pipe road 120 is stretched out from the inside of fluid reservoir 110.

In this way, due to being equipped with air inlet 111 and infusion port 112 on fluid reservoir 110, and outlet pipe 120 is from fluid reservoir 110 inside is stretched out, and can thus be inputted to fluid reservoir 110 liquid by infusion port 112, then be passed through air inlet 111 will may be such that the liquid in fluid reservoir 110 comes out out of outlet pipe 120 in gas press-in fluid reservoir 110.This practicality is tied Structure is simple, can adapt to the extraction or transfer of various different liquids.

There is no any mechanical part inside fluid reservoir 110, therefore be not in evacuation, machine it was found from the above Tool sealing wear, motor burn out and due to caused by corrosion the problems such as leakage, because the fluid pressure differential apparatus structure is simple, Therefore with little need for repair, moreover it is possible to exempt the maintenance cost of device.

It should be noted that embodiment according to the present utility model, the specific species and shape of fluid reservoir 110 do not limit It is fixed.For example, in some embodiments, fluid reservoir 110 can be cylindric.In other embodiments, fluid reservoir 110 can To be rectangular-shape.In other embodiments, fluid reservoir 110 can also be in up-narrow and down-wide shape.

Furthermore it is also possible to the side wall in fluid reservoir 110 opens up an observation window sealed, for observing fluid reservoir in real time The surplus of liquid in 110.

In some embodiments, air inlet 111, infusion port 112 and outlet pipe 120 are respectively one.At this point, air inlet Mouth 111 and infusion port 112 are arranged at the top of fluid reservoir 110, so on the one hand can conveniently be infused by infusion port 112, On the other hand when the liquid inside fluid reservoir 110 is more, it can facilitate and gas is pressed into fluid reservoir 110.

In the utility model embodiment, infusion port 112 is arranged on the middle position at the top of fluid reservoir 110, and air inlet Mouth 111 sets the both ends at 110 top of fluid reservoir with outlet pipe 120 respectively, and positioned in the both sides of infusion port 112.

In this way, when liquid is transported to fluid reservoir 110, it is ensured that liquid is fallen into from the centre position of fluid reservoir 110 Into fluid reservoir 110 so that during liquid is conveyed, the side wall of fluid reservoir 110 will not be subject to the extruding of liquid and cause The beat of fluid reservoir 110.Particularly when lighter weight, the small volume of fluid reservoir 110, said effect is more obvious.

On the other hand, air inlet 111 and the above-mentioned setting of outlet pipe 120, can cause air inlet 111 and outlet pipe The distance between 120 relatively far apart, when the air pressure of gas is enough liquid extruding fluid reservoir 110, can protect to a certain extent Demonstrate,prove the stability of liquid from outlet pipe 120 out.

Certainly, in other embodiments, air inlet 111, infusion port 112 and outlet pipe 120 can be it is multiple, together When, air inlet 111 can be corresponded with infusion port 112, can also be one-to-many and set.

For example, in some embodiments, two air inlets 111 can be set on fluid reservoir 110, set one and go out liquid Pipeline 120 so when needing liquid being transported to higher position, can input gas, energy by two air inlets 111 simultaneously It is enough that liquid is quickly more transported to specified altitude assignment.

Certainly, in other embodiments, more air inlets 111, the specific number of air inlet 111 can also be arranged to Mesh can be depending on actual demand.

For another example, in some embodiments, demarcation strip can be set in the inside of fluid reservoir 110 and by fluid reservoir 110 Inner space is divided into two, and forms two sub-spaces.So so that two kinds of liquid can be stored in same fluid reservoir 110, And each sub-spaces correspond to an air inlet 111, infusion port 112 and outlet pipe 120.

In this way, same fluid reservoir 110 can transfer out two kinds of liquid, both liquid can convey separately or together To miscellaneous equipment, such as mixer etc..

Certainly, with reference to foregoing, each sub-spaces can also correspond to multiple air inlets 111, infusion port 112 and outlet pipe 120。

It should be noted that in some embodiments, the height of bottom of the outlet pipe 120 from fluid reservoir 110 can fit Degree increases, and so when what is stored in fluid reservoir 110 is the high liquid of viscosity or easy crystallized liquid, can prevent above-mentioned liquid Body is blocked in the import of outlet pipe 120.

In addition, the internal diameter of outlet pipe 120 can be increased suitably, further prevent aforesaid liquid outlet pipe 120 into Mouth blocks.

In some embodiments, outlet pipe 120 can be inclined in fluid reservoir 110, so that liquid energy What is be enough more prone to is pressed into from fluid reservoir 110 to outlet pipe 120 by gas, is come out using outlet pipe 120.

Further, outlet pipe 120 is in the part of fluid reservoir 110, can set multiple siphon holes on their outer circumference, It can allow fluid to more easily enter in outlet pipe 120 by the effect of siphon hole.At this time it is appreciated that liquid It can enter from the end of outlet pipe 120, can also enter from the surface of outlet pipe 120, can so promote liquid pumping The effect for taking or shifting.

In some embodiments, fluid reservoir 110 and outlet pipe 120 can be used erosion-resisting material and be made, so when 110 internal storage of fluid reservoir be corrosive liquids when, can prevent the liquid from being made to fluid reservoir 110 or outlet pipe 120 Into damage.

In addition, fluid reservoir 110 and outlet pipe 120 can also be used conventional material and be made, and in fluid reservoir 110 and outlet tube The outer surface in road 120 increases by one layer of erosion resistant coating, achieve the effect that with it is above-mentioned identical using corrosion-resistant material.

Either erosion resistant coating can select ND steel, stainless steel or glass etc. to above-mentioned corrosion-resistant material.

It should be noted that outlet pipe 120 can be fixedly mounted on fluid reservoir 110, outlet pipe 120 and liquid storage at this time Tank 110 can form integrated structure.In addition, outlet pipe 120 can also be removably mounted at fluid reservoir 110 On, so replaced convenient for outlet pipe 120.

It in the utility model embodiment, please refers to Fig.1, fluid pressure differential device 100 further includes fluid infusion structure 130, should For liquid to be delivered in fluid reservoir 110, fluid infusion structure 130 is mounted at infusion port 112 fluid infusion structure 130.

Further, fluid infusion structure 130 includes transfusing chamber 131 and check valve 132, and transfusing chamber 131 connects with infusion port 112 Logical, check valve 132 is arranged on the bottom of transfusing chamber 131, and check valve 132 is connected from transfusing chamber 131 to the direction of infusion port 112.

In this way, the effect by fluid infusion structure 130, it is ensured that liquid can be smoothly inputted to fluid reservoir 110, may be used also Prevent gas from being leaked from infusion port 112.

In some embodiments, transfusing chamber 131 is in funnel-form, is further ensured that liquid can smoothly be input to liquid storage In tank 110.

It is appreciated that fluid infusion structure 130 is connected with external fluid delivery apparatus, it at this time can be fine in funnelform transfusing chamber Dock with external fluid delivery apparatus generation so that fluid delivery apparatus during liquid quantitatively is transported to fluid reservoir 110, Liquid will not leak.This is particularly important during chemical industry is carried out with liquid.

In some specific embodiments, check valve 132 can select hydraulically-controlled one-way valve.
