Abstract
The utility model relates to a controllable low-pressure one-way valve. The controllable low-pressure one-way valve has the advantage of not being a traditional one-way valve or water valve; firstly, when serving as a one-way valve, utilizing the characteristic of easy deformation of the soft rubber sheet of a hydraulic gate to plug a liquid inlet under a low water pressure instead of a high water pressure to close a one-way hydraulic valve; secondly, being capable of being opened in two modes including that one comprises pressing liquid in via the liquid inlet through external force and then form a liquid guide port to a liquid outlet and lastly out of a valve cavity, and the other comprises opening a control pump to reduce the pressure of a pressure detecting chamber and further open the hydraulic gate, during which the liquid flows from the liquid outlet into the air inlet through the liquid guide port and then out of the valve cavity. Therefore, the one-way valve is changed into a controllable valve, and further operation of the controllable one-way valve can be achieved.
Description
Technical field:
The utility model relates to a kind of unidirectional pressure valve of controlled low pressure of liquid, and this valve is not in the situation that controlling power supply, unidirectional closing, but after power supply, it is the same with common valve again, one side of original blocking-up can be opened and closed, be mainly used in some low hydraulic pressure occasion, as fish pond, fish jar fishpond etc.
Background technique:
At present liquid flow check valve on the market and automatically controlled fluid valve, its working principle is all made up of valve pocket and spool substantially, spool is pressed onto and on valve pocket, just closes liquid stream, separate and just open liquid stream, in these designs, there is a common ground, be exactly that spool adds flexible glue by hard thing and forms, when its sealing, complete by the flexible glue deformation of surface of contact, and the power that this is closed causes by differential water pressures or the mechanical energy on one-way valve both sides, but some use occasion is to accomplish very high differential water pressures, such as fish jar fishpond etc., water higher position is tens centimeters so, to produce enough pressure, tend to like this cause the one-way valve can not tight closing, as closed with mechanical energy compressing, while opening, just need same large kinetic energy just can open.
Model utility content
In order to overcome the shortcoming that one-way valve can not tight closing in the situation that hydraulic pressure is not high, and common valve needs the shortcoming of very large mechanical kinetic energy when opening, and the utility model provides a kind of controlled low pressure check valve.The hydraulic pressure of its need of work is the in the situation that of several centimeters of hydraulic pressure, low pressure check valve that just can tight closing, when opening, there are two kinds of situations simultaneously, the one, oppositely add hydraulic pressure, the 2nd, utilize little water pump to press storehouse to produce negative pressure in inspection liquid gate is opened, and in the process that valve is opened at this, water resistance of its generation is also very little.
First in a valve pocket, put in a liquid inlet pipe, and be fixed in valve pocket, one end of liquid inlet pipe is connected to the outside of valve pocket, the other end is blocked by liquid gate, liquid gate be one can be concavo-convex up and down cushion compound, liquid gate is the substrate that has fluid guidance port and liquid entering hole below, and between this substrate and valve pocket, being has the gap can be to flow of fluid, and periphery and liquid gate tightly fixing, the tested pressure of liquid gate storehouse is airtight, and inspection is pressed storehouse to have convection holes and controlled mouthful, controls mouthful connecting control water pump, and pump discharge is in valve pocket, when liquid is filled with valve pocket by liquid outlet direction, also do not open and at this moment control water pump, the control mouth that liquid is connected with control water pump by convection holes pours into inspection liquid and presses in storehouse, the power that this sample liquid gate is subject at liquid entering hole two ends be valve pocket inside higher than outside, and the area of the corresponding liquid gate of fluid guidance port is due to all in valve pocket, so bearing up-down force is substantially equal, that is to say, liquid gate is subject to the power from inside outwards pushing away, therefore liquid gate is overlayed on liquid entering hole, liquid gate be one can be concavo-convex up and down cushion compound, it can be along liquid entering hole generation deformation, do not need so very large power just can liquid entering hole give blocked closely, liquid is thoroughly blocked, now controlled low pressure check valve is in closed condition, another situation is to be subject to the pump drainage of liquid outlet or to have a power that liquid is entered to valve pocket from liquid entering hole when the liquid of valve pocket, at this moment no matter whether control pump is opened, liquid gate can leave liquid entering hole, liquid can pass through liquid entering hole, follow the jacking due to liquid gate, liquid enters valve pocket from fluid guidance port, flows out finally by crossing liquid outlet, and at this moment controlled low pressure check valve is in a kind of open mode, also having a kind of situation is that liquid is filled with valve pocket by liquid outlet direction, open and at this moment control water pump, liquid is controlled water pump and is pressed in storehouse by controlling mouthful pump drainage out from inspection, and the liquid that enters of convection holes not control the pump drainage of water pump fast, inspection presses the liquid in storehouse to many and supplementary the lacking of taking away like this, inspection presses storehouse will produce negative pressure, there is variation in the power that liquid gate is subject at fluid guidance port two ends, the power that has so just become valve pocket one side is large, and inspection presses the power of inside, storehouse little, and in the time that the summation of this power is greater than the power of pushing down liquid entering hole, liquid gate will leave liquid entering hole, at this moment liquid will enter valve pocket from liquid outlet, then flow out valve pocket through liquid entering hole again by fluid guidance port, at this moment controlled low pressure check valve is also in open mode, but liquid flow path direction is put upside down.
Liquid gate be one can upper and lower concavo-convex cushion compound, can overlay on liquid entering hole by its deformation, thereby block liquid entering hole and close liquid valve, also can be bent upwards by it simultaneously, leave liquid entering hole and open valve.
Liquid gate can not singly be covered with liquid entering hole, and its area is larger than liquid entering hole, and wants to cover liquid entering hole and fluid guidance port.
Liquid gate one side is relative with fluid guidance port with liquid entering hole, and the tested pressure of another side storehouse seals and closing, and presses storehouse to have convection holes and control mouth in inspection.
The convection holes of pressing storehouse to open in inspection is less than control mouth in principle, because require to open when controlling water pump, and when pump drainage is examined the liquid in pressure storehouse, be faster than the speed of convection holes feed liquor body, inspection presses storehouse just can produce negative pressure for liquid gate like this.
It is that an approach in storehouse is pressed in liquid discrepancy inspection that the control mouth in storehouse is pressed in inspection, starts if control water pump, and the liquid in inspection pressure storehouse is just from being discharged to here valve pocket.
Between the substrate that has fluid guidance port and liquid entering hole being covered with by liquid gate and valve pocket, must there is certain gap can allow flow of fluid pass through, because liquid is by flowing into or flowing out liquid entering hole here.
Fluid guidance port is unique passage of liquid turnover liquid entering hole, and this valve also can be used as controlled valve as one-way valve simultaneously, so liquid can flow to or flow out liquid entering hole.
Valve pocket be UNICOM's liquid entering hole and liquid outlet excessively between passage, be exactly by the parcel of this valve pocket, finally connected the pipeline of outside by two interfaces.
The beneficial effects of the utility model are, controlled low pressure check valve is not traditional one-way valve or water valve, first as one-way valve time, it does not need very high hydraulic pressure just can close liquid valve, but utilize dexterously the easier characteristic of this cushion compound deformation ratio of liquid gate, the in the situation that of low hydraulic pressure, just liquid entering hole can be blocked, unidirectional liquid valve cuts out; Just there are two kinds of modes and open, one is exactly that liquid is compressed into by external force from liquid entering hole, fluid guidance port flows to liquid outlet, then flows out valve pocket, and the secondth, open by control pump, reduce inspection and press the pressure in storehouse, thereby open liquid gate, at this moment liquid is to enter from liquid outlet, then enter liquid entering hole outflow valve pocket by fluid guidance port, thereby one-way valve is become to a controlled valve, realized the work of controllable check valve.
