Detailed description of the invention
As shown in Figure 1, the end socket 2 of filter feed liquor pressure-equalizing device is a conical head, and the cone top part of this conical head, is bored bottom-up down; The portlet of end socket 2 is positioned at the cone top part of conical head, and by Flange joint pipeline; The large port of end socket 2 is positioned at bottom the cone of conical head, and by Flange joint filter housing.Wherein, term " large port " and " portlet " are only there is difference in size for the ease of expressing between these two ports.Certainly, the shape of end socket 2 also can be arc or even rectangle, but no matter how the shape of end socket 2 changes, its one end will connect filter housing, and the other end also will connecting pipe, therefore, in general, the port this end socket 2 connecting filter housing must be large port, and the port of connecting pipe must be portlet.Point pressing plate 3 near end socket 2 large port in end socket 2 can be seen from the visual angle of Fig. 2, and a lot of tap holes 4 on this point of pressing plate 3 that gather, and also known this point of pressing plate 3 must be positioned at the cross section of end socket 2 from the visual angle of Fig. 2, therefore, the large port of end socket 2 is flowed to dispersedly after the tap hole 4 that the liquid of the portlet inflow end socket 2 of end socket 2 will be gathered by this point of pressing plate 3, thus improve the uniformity of filter core 1A, 1B, 1C porch fluid pressure distribution, effectively avoid the fluid pressure too concentration phenomenon of filter core 1B porch.
Easy understand, if the one piece of point of pressing plate 3 just only having as can be seen from Fig. 2 in whole end socket 2, so this point of pressing plate 3 should not be arranged on too on the cross section of end socket 2 portlet.This is because limitting by conical head shape, this point of pressing plate 3 is the closer to the portlet of end socket 2, and the area of this point of pressing plate 3 is less, therefore the result of use of point pressing plate 3 also can be poorer.Therefore, the present invention advises, no matter in end socket 2, is provided with several pieces point pressing plates 3, near end socket 2 large port divide pressing plate 3 described large port projected area in the plane preferably account for more than 60% of this large port area.That is, when just only having one piece of point of pressing plate 3 as can be seen from Fig. 2 in whole end socket 2, as long as this point of pressing plate 3 described large port projected area in the plane account for more than 60% of this large port area, in fact just ensure that this only one piece of point of pressing plate 3 can not be arranged on too on the cross section of end socket 2 portlet in end socket 2.And when being provided with at least two pieces of points of pressing plates 3 in whole end socket 2, also ensure that point pressing plate 3 near end socket 2 large port can not be arranged on too on the cross section of end socket 2 portlet in end socket 2 equally.In a word, by guaranteeing the area of point pressing plate 3 near end socket 2 large port, fully ensureing the diffusion of point pressing plate 3 pairs of liquid towards end socket 2 large port direction, further improve the uniformity of fluid pressure distribution.
As shown in Figure 3, in described end socket 2, in fact axially spaced-apart is provided with two pieces of points of pressing plates 3A, 3B.It is self-evident for being provided with two pieces even advantage of more points of pressing plates.The average diameter of tap hole 4 on pressing plate 3B of dividing leaned on into end socket 2 portlet on this basis, is designed to be greater than the average diameter leaning on tap hole 4 on point pressing plate 3A of end socket 2 large port by the present invention.This is because, the closer to the portlet of end socket 2, fluid pressure distribution is more concentrated, the larger of the average diameter design of tap hole 4 on point pressing plate 3B of end socket 2 portlet will be leaned on, this point of pressing plate 3B can be reduced to the resistance of liquid flow, otherwise, the excessive transmembrane pressure that just may reduce cartridge surface of resistance, thus adverse effect is caused to whole filtration system.In addition, when lean on into the average diameter of the upper tap hole 4 of point pressing plate 3B of end socket 2 portlet be greater than lean on into end socket 2 large port divide the average diameter of tap hole 4 on pressing plate 3A time, in fact the degree of scatter of fluid pressure in end socket 2 is made to be step change, namely progressively by fluid pressure distribution uniformity, thus by the relatively milder of liquid flow control and can stablize.
As shown in Fig. 3,6, no matter several pieces points of pressing plates 3 are installed in end socket 2, point be also provided with rectifying component 5 between pressing plate 3B and the portlet of this end socket 2 near end socket 2 portlet, described rectifying component 5 is made up of at least two flow deflectors arranged vertically respectively 51.Point out above, the closer to the position of end socket 2 portlet in end socket 2, fluid pressure distribution is more concentrated, therefore once be subject to a point stop of pressing plate 3B, more easily forms turbulent flow, thus consumable liquid kinetic energy.Therefore, the present invention, by each flow deflector 51 arranged vertically on rectifying component 5, makes liquid feed towards the axially-movable of end socket 2, reaches unified thus and flows to, reduce the object of fluid energy loss.As a kind of concrete structure of rectifying component 5, as shown in Figure 6, the flow deflector 51 that rectifying component 5 is connected by two right-angled intersections is formed.
As shown in Figure 4,5, no matter be depend on point pressing plate 3A into end socket 2 large port, still depend on point pressing plate 3B into end socket 2 portlet, on same point of pressing plate 3 each tap hole 4 equal diameters and on this point of pressing plate 3 rectangular array, and spacing wherein between arbitrary neighborhood two tap holes 4 is consistent.Need to illustrate, all refer to depict a tap hole 4 in Fig. 4,5, but those skilled in the art are readily appreciated that, in Fig. 4,5, namely the intersection point of any two reference lines indicates the central point of a tap hole 4.Therefore, easily find out, tap hole 4 is carried out cloth postpone in such a manner, on point pressing plate 3, the distribution of tap hole 4 is the most uniform.
As shown in Figure 3, no matter be depend on point pressing plate 3A into end socket 2 large port, still depend on point pressing plate 3B into end socket 2 portlet, these two pieces of points of pressing plates 3 are all positioned on the cross section of end socket 2, and at this moment, these two pieces of points of pressing plates 3 just equal 90 degree with the angle α of end socket 2 axis.Certainly, these two pieces of points of pressing plates 3 also can be positioned at and exist on other cross sections of certain angle with the cross section of end socket 2, as long as flow to the large port of end socket 2 dispersedly after guaranteeing the tap hole 4 that the liquid flowing into end socket 2 from the portlet of end socket 2 can be gathered by this point of pressing plate 3.Certainly, the angle α of these point of pressing plate 3 and end socket 2 axis is preferably between 70 degree to 90 degree.
