Abstract
The utility model discloses an intelligent liquid flow control valve. A cylinder body comprises an upper cylinder body and a lower cylinder body which are separated in the middle and connected into a whole. A rotary vane is arranged in the upper cylinder body. The upper cylinder body is filled with magnetic-rheological fluid. The outer side of the upper cylinder body is wound by coils. A gear with the upper face and the lower face attached to the upper inner wall and the lower inner wall of the lower cylinder body respectively is arranged in the lower cylinder body. The rotary vane is connected with the gear through a shaft rod. The lower cylinder body is divided into a left cylinder body and a right cylinder body through the gear. A liquid inlet and a liquid outlet are formed in the left cylinder body and the right cylinder body respectively. The intelligent liquid flow control valve is simple in structure, convenient to machine, strong in economical efficiency and free of manual operation. The mobility of the magnetic-rheological fluid can be changed through the adjustment of a current, so that the rotating speed of the gear is changed and continuous control over the flow and the pressure of the two ends of the valve is achieved. Due to the fact that the rheological character of the magnetic-rheological fluid is controlled through the current, the accuracy of control over the flow and the pressure of the two ends of the valve is high.
Description
Technical field
The utility model relates to a kind of flow-control equipment, relates in particular to a kind of intelligent liquid flow control valve.
Background technique
Flow control valve is called for short Flow valve, and it comprises throttle valve, series flow control valve, overflow throttle valve and flow divider-combiner.Traditional Flow valve is to change the size of local resistance by the length that changes choke area or passage, thereby realizes the control to flow, and then changes movement velocity and the size of the pressure in cylinder body that valve connects of actuator.The general more complicated of the structure of traditional Flow valve, and its control to changes in flow rate is to rely on the variation of valve body internal pressure to regulate, its pressure when cylinder interior is when external condition changes, need carry out a series of feedback regulation, carry out repeatedly repeatedly, just can reach the flow of expection, it is passive and slow that its adjustment process is regulated.Utilize pure machinery to come the flow of control valve and the pressure at valve two ends, poor continuity and not intelligent.If can design a kind of simple and practical flow control valve, in the situation of changes in flow rate or external condition needs, can control Flow valve by program, flow is carried out control initiatively, make Flow valve realize intelligent; Can accept feedback and also can control voluntarily, the ducted pressure of adjust flux control valve is big or small very easily, and makes the pressure of pipeline change continuously,, if implemented, has very large Practical significance.Along with the development of science and technology, magnetic flow liquid more and more is used in every field, but in this field of flow control valve, does not have too many relating to.Magnetic flow liquid is subject to electromagnetic field and changes the characteristics of nowed forming,, if be used to flow control valve, can realize intellectuality, continization that flow and pipeline pressure are controlled, has great importance in actual applications.
The model utility content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of intelligent liquid flow control valve based on the magnetic flow liquid characteristic is provided.
The utility model is achieved through the following technical solutions:
a kind of intelligent liquid flow control valve, include cylinder body, cut off in the middle of described cylinder body includes and be connected as a single entity upper, lower cylinder body, be provided with rotation blade in described upper cylinder body, upper cylinder body inside is full of magnetic flow liquid, outer felt at upper cylinder body is wound with coil, be provided with in described lower cylinder body, below upper with lower cylinder body respectively, the gear of lower inwall laminating, described rotation blade is connected an axostylus axostyle and connects with gear, described gear is divided into a left side with lower cylinder body, right cylinder body, on a left side, be respectively equipped with liquid entering hole and liquid outlet on right cylinder body, when having liquid to flow in left cylinder, left, right cylinder body has pressure difference, pressure promotes gear and rotates, the liquid of left cylinder flows into right cylinder body with the rotation of gear, the rotation of gear drives the rotation of axostylus axostyle, the rotation of the rotation driven rotary blade of axostylus axostyle, when coil is not switched on, the character of magnetic flow liquid shows as low viscous Newtonian fluid characteristic, the viscosity of magnetic flow liquid is minimum, magnetic flow liquid is minimum to the resistance that the rotation of rotation blade produces, the rotating speed of gear is maximum, be that flow is maximum, after coil electricity stream, under the effect in magnetic field, the viscosity of magnetic flow liquid slowly increases, mobility dies down, magnetic flow liquid constantly increases the resistance of rotation blade, the rotating speed of gear constantly reduces, flow constantly reduces, electric current continues to increase, when being increased to a certain value, gear is not rotated, flow control valve is in the state that turn-offs fully, shear yield strength and magnetic intensity due to magnetic flow liquid after its rheology have stable corresponding relation, therefore can carry out continuous control to the size of flow.
Be equipped with keyway on the inner ring of described rotation blade and gear, described axostylus axostyle is provided with flat key, and axostylus axostyle is connected by flat key with gear with rotation blade, reaches the synchronism of rotation.
Be connected by sliding bearing respectively between the upper and lower end of described axostylus axostyle and upper and lower cylinder body.
Gap location between described axostylus axostyle and upper and lower cylinder body is provided with seal ring and seal sleeve, guarantees good sealing.
The utility model in use, the rheological properties of the magnetic flow liquid in upper cylinder body be subjected to that the outer hot-wire coil of cylinder body produces the control of induction field.When electric current on hot-wire coil was zero, magnetic flow liquid presented low viscous Newtonian fluid characteristic; And when electric current on hot-wire coil constantly increased, magnetic flow liquid presented the Bingham body characteristics of high viscosity, lazy flow in the magnetic field that produces.Along with the viscosity of magnetic flow liquid constantly increases, the suffered resistance of rotation blade constantly increases, and the rotating speed of gear is more and more slower, is finally zero, and the flow of flow control valve is more and more less, until be zero, this flow control valve is off state.
The utility model has the advantages that: the utility model processing simple in structure, convenient, Economy is strong, need not manually-operable, can change by regulating size of current the mobility of magnetic flow liquid, thereby change the rotating speed of gear, to reach size and the continuous control of valve pressure at two ends size to flow, and this control is intelligent, can be by real-time feedback, also can be by the setting of program, rheological properties due to magnetic flow liquid is to rely on electric current to control again, therefore its control to uninterrupted and valve pressure at two ends size is precisely read higher.
