Abstract
The utility model provides a design scheme of a self hydraulic type bottom discharging valve. The most prominent characteristic of the scheme is not to use an external force to control a valve core and a valve cavity to disconnect or connect to open or close a fluid valve, but to use a hydraulic pressure generated by the liquid in a container to realize the above process. Firstly, by utilizing the principle that the hydraulic pressure in the container is greater than the hydraulic pressure out of the container, a liquid gate is pressed on a liquid discharging hole to block the liquid discharging hole, so that the fluid valve is closed. When the fluid valve needs to be opened, a water pump is used to pump out the liquid in a pressure detection cabin, and the liquid discharging speed in the pressure detection cabin is enabled to be greater than the liquid charging speed, so that a negative pressure is generated above the liquid gate, while the part corresponding to a liquid guide hole below the liquid gate is applied with an upward pushing force of the hydraulic pressure below the liquid, when the pushing force is greater than the pressure above the liquid discharging hole, the liquid gate is pushed up to be opened, the liquid flows into the liquid discharging hole by the liquid guide hole and flows out of the container, at this time, the self hydraulic type bottom discharging valve is opened. The hydraulic pressure of the liquid is made the best of in the whole process, so that the energy consumption is saved.
Description
Technical field:
The utility model relates to valve of a kind of end, and the hydraulic pressure that particularly utilizes liquid in container, to produce is used as controlling the main active force of fluid valve switch.
Background technique:
Fluid valve generally all is made up of valve pocket and spool at present; Spool is pressed onto and just closes fluid valve on the valve pocket; Separate and just to open fluid valve, its kinetic energy has electric energy, pneumatic energy and general mechanical kinetic energy, the fluid valve of being made up of valve pocket and spool like this; It opens or closes all and under external active force, accomplishes, and the hydraulic coupling that liquid produces is the resistance that this active force must overcome.Need very big the time when the bore of fluid valve like this, the demand of the power that it opens or closes is also very big.This just has certain use difficulty for some automation application place.
For example fish jar, fishpond think that profit wants to come suction to filter with its hydraulic pressure; Just need a bigbore delivery pipe and a bigbore fluid valve, produce big current, could be the fish excrement suction at the bottom; But often these containers that are filled with water can be very not big; Even its structure is not owing to be consideration in the industry, and the needs of just viewing and admiring are therefore thiner; If at this moment a bigbore solenoid valve or pneumatic valve are installed firmly, the noise of its generation and with the cooperation of other accessory be that very big difficulty is arranged.For example: solenoid valve has a big coil, and coil can not touch water, and the problem of bigger vibrations is arranged, and seems very inconvenient with the fixing whole valve of support; And pneumatic valve just needs powerful air compressor as cooperating annex; Powerful air compressor also has the big problem of noise except consuming energy greatly; So in this occasion is that the application of solenoid valve, pneumatic valve and general manual fluid valve is all difficult, and needs better technological improvement.Such application is characterized in that the mobile of water is unidirectional, only need flow out from the bottom in fish jar, fishpond, and the material that has precipitated the bottom is in the lump taken away together.And water intake is set up in addition.And this fish jar, fishpond filled with after the water, along with the increase of the degree of depth of water, can produce a very big hydraulic pressure in the bottom of water, and this big hydraulic pressure is exactly utilizable kinetic energy.
The model utility content
Need the shortcoming of the existing fluid valve existence of high-power driving in order to overcome bigbore fluid valve; The utility model provides a kind of valve at the bottom of liquid controls fluid valve at the hydraulic pressure that container bottom produces the self-pressure type of opening and closing that utilizes; Fill certain liquid in its need of work container, and the hydraulic pressure in the container is greater than the outer hydraulic pressure of container.
Valve at the bottom of the self-pressure type is the bottom that is fixed on container with a liquid-discharging tube, liquid-discharging tube lower end and container outside UNICOM; The upper end by the shutoff of liquid gate, and the area of liquid gate is bigger than liquid-discharging tube bore, and the liquid gate is made of flexible glue class thin slice; Can be concavo-convex up and down, the top periphery of liquid gate is pressed the storehouse tightly to cover by an inspection, and inspection presses the upper end, storehouse to have inlet opening and liquid outlet opening; Should there be fluid guidance port and liquid port in liquid gate below relatively; Fluid guidance port down, the liquid of container can flow into, inspection presses the storehouse to be provided with water pump.When water pump cuts out, examine and press the storehouse owing to have liquid entering hole, so inspection presses the storehouse to fill with the liquid of container, the liquid gate receives the active force of hydraulic pressure; The liquid gate is overlayed on liquid port, and liquid is blocked outside liquid gate and liquid port, and liquid can not flow container, and at this moment valve is in closed condition at the bottom of the self-pressure type; Water pump is opened, and inspection presses the liquid in storehouse to discharge from liquid outlet opening, and drain age velocity is faster than feed liquor speed; Inspection presses the liquid in storehouse to reduce, so liquid gate top produces a negative pressure, and the hydraulic pressure jacking that liquid gate below is made progress by fluid guidance port; Power like this is greater than top power, and the liquid gate is left liquid port by jack-up; Liquid just can get into liquid port through fluid guidance port, and along the liquid-discharging tube flow container, valve is in open mode at the bottom of the self-pressure type.
The area of liquid gate is bigger than the area of liquid port, and this is because must leave the position of fluid guidance port.
Water pump is that the liquid in the storehouse is pressed in the pump drainage inspection, and this pump needs very little power just enough, because it only need press inspection the liquid in storehouse to reduce just passable.
Inspection presses the upper end in storehouse to have inlet opening and liquid outlet opening, and inlet opening is to leave liquid for to get into the mouth that the storehouse is pressed in inspection, and liquid outlet opening is exactly the mouth that the pump handle inspection presses the liquid pump drainage in storehouse to come out.
Fluid guidance port is positioned at the below of liquid gate, and it is high that want container bottom, and the liquid of internal tank can flow to the below of fluid guidance port, because liquid is to have turned a curved flow container here.
The beneficial effect of the utility model is; Valve is not traditional fluid valve that kind at the bottom of this self-pressure type, needs powerful outer power overcome the resistance that liquid produces, and the cooperation that just reaches control valve pocket and spool opens or closes; But utilized this principle of hydraulic difference dexterously; Closing is the single effect of hydraulic pressure fully, and opening then is to utilize some subregional negative pressuren zones of outer kinetic energy manufacturing department, the effect that still utilizes its hydraulic coupling at last self-pressure type at the bottom of valve open; Its kinetic energy consumption is few, and the vibrations of generation and noise are also few.The liquid that a bit is suction in addition is to begin from container bottom, meets the requirement that fish jar, fishpond filtration need water at the bottom of the suction so most.
