Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
Example 1
As shown in FIG. 1, the control mechanism of the floating precision flow valve comprises an electromagnetic coil, a base 1, a ring seat 2, a floating component 3 and an elastic sheet 4; the elastic sheet 4 is positioned above the base 1, the ring seat 2 and the floating component 3 are positioned between the base 1 and the elastic sheet 4, and the floating component 3 is positioned on the inner side of the ring seat 2.
A plurality of arc-shaped retaining walls are arranged on the outer circumference of the upper side of the base 1, the upper surfaces of the arc-shaped retaining walls are flush, the ring seat 2 falls on the arc-shaped retaining walls, and an air inlet opening structure is formed between the adjacent arc-shaped retaining walls; of course, the air inlet opening structure can be transferred to the lower end of the ring seat 2 without designing an arc-shaped baffle wall structure on the base 1.
The lower part of the floating component 3 is a conical part 8, the base 1 is provided with a flow passage hole 7, the top of the flow passage hole 7 is provided with a conical surface structure, and the conical surface structure is matched with the conical part 8 so that the conical part and the conical part can be completely attached; of course, the top of the flow passage hole 7 may not be provided with a tapered surface structure, and only the bottom of the tapered portion 8 may be required to completely block the flow passage hole 7.
The upper part of the floating component 3 is provided with a convex part 9, and the convex part 9 can enable a round table or a frustum structure to enable the floating component 3 to press the elastic sheet 4 more easily, so that the elastic sheet 4 generates downward elastic force on the floating component 3.
Example 2
As shown in fig. 2, the difference from embodiment 1 is that the floating member 3 is a spherical structure, and the upper and lower portions of the spherical structure are both arc surfaces, which meets the characteristic requirements of reducing the bernoulli effect and making it easier to touch the pressing spring 4.
Example 3
As shown in fig. 3, the difference from embodiment 2 is that the floating member 3 is a hemispherical structure, the lower portion of the hemispherical structure is a circular arc surface, so as to reduce bernoulli effect, and the upper portion of the hemispherical structure is provided with a protrusion 9, so that the floating member 3 can more easily touch the pressing spring 4.
Besides the 3 embodiments described above, other structures with similar effects, such as trapezoidal, kidney-shaped, etc., can be selected for the floating member 3.
The electromagnetic coil is positioned at the upper side of the elastic sheet 4, and after the electromagnetic coil is electrified, the electromagnetic coil generates upward magnetic attraction force F to the floating component 31After the floating component 3 moves upwards, the elastic sheet 4 is pressed, so that the elastic sheet 4 generates downward elastic force F on the floating component 32When fluid passes between the floating member 3 and the base 1, a downward force F is applied to the floating member 3 by the Bernoulli effect3(ii) a Changing the magnetic attraction force F by changing the current of the magnet coil1，F1Overcome F2And F3And the gravity of the floating member 3 itself to control the opening degree of the floating member 3; different flow rates can be generated by different opening degrees, so that the effect of precisely controlling the micro flow rate is achieved; typically, the opening of the floating member is no greater than 800 microns.
The base 1 can be further provided with a sealing ring 5 matched with the floating component 3, the sealing ring 5 needs to be provided with a structure avoiding the flow passage hole 7, when the electromagnetic coil is not electrified, the floating component 3 falls on the sealing ring 5 to seal the flow passage on the base 1, the sealing ring 5 can be designed with the structural characteristics matched with the lower structure of the floating component 3, and the sealing ring 5 can be made of Teflon, nitrile rubber, silica gel and other materials.
Of course, if the seal ring 5 is fixedly provided at the lower portion of the floating member 3, the seal ring 5 does not need to be provided with a structure for avoiding the flow passage hole 7, but it is highly required to be fitted and fixed to the lower protruding structure of the floating member 3.
When only a slight leak exists between the base 1 and the floating member 3, the seal ring 5 may not be provided.
For the sake of illustration, the parts are slightly separated, and in practice, the lower side of the ring seat 2 should be close to the base 1, and the spring plate 4 should be pressed against the upper side of the ring seat 2 by the electromagnetic coil; in the drawings of the embodiments 2 and 3, the diameters of the base 1, the ring seat 2 and the elastic sheet 4 are all reduced, so that the ring seat 2 is in clearance fit with the spherical structure; the other similar structures are the same.
