The specific embodiment
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 the flange connections road; The large port of end socket 2 is positioned at the awl bottom of conical head, and connects filter housing by flange.Wherein, term " large port " and " portlet " only are to have 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, the one end will connect filter housing, and the other end also will connecting pipe, therefore, and in general, the port that connects filter housing on this end socket 2 must be large port, and the port of connecting pipe must be portlet.Can see the branch pressing plate 3 of the most close end socket 2 large ports in the end socket 2 from the visual angle of Fig. 2, and a lot of tap holes 4 on this minute pressing plate 3 of gathering, and from the visual angle of Fig. 2 also as can be known this minute pressing plate 3 must be positioned on the cross section of end socket 2, therefore, from flowing to the large port of end socket 2 after the portlet of end socket 2 flows into the tap hole 4 that the liquid of end socket 2 will gather by this minute pressing plate 3 dispersedly, thereby improve the uniformity that filter core 1A, 1B, 1C porch fluid pressure distribute, the fluid pressure of effectively avoiding filter core 1B porch is concentration phenomenon too.
Understand easily, if just have only as can be seen from Fig. 2 a branch pressing plate 3 in the whole end socket 2, pressing plate 3 should not be installed in too near on the cross section of end socket 2 portlet this minute so.This be because, limit by the conical head shape, this minute pressing plate 3 the closer to the portlet of end socket 2, this minute pressing plate 3 area just more little, so the result of use of branch pressing plate 3 also can be more poor.Therefore, no matter the utility model suggestion is equipped with several branch pressing plates 3 in end socket 2, and the projected area of the branch pressing plate 3 of the most close end socket 2 large ports on plane, described large port place preferably accounts for more than 60% of this large port area.That is to say, when branch pressing plate 3 just having only in the whole end socket 2 as can be seen from Fig. 2, as long as the projected area of this minute pressing plate 3 on plane, described large port place accounts for more than 60% of this large port area, in fact just guaranteed that this only branch pressing plate 3 can not be installed in too near on the cross section of end socket 2 portlet in end socket 2.And when in the whole end socket 2 at least two branch pressing plates 3 being installed, guaranteed that equally also the branch pressing plate 3 of the most close end socket 2 large ports can not be installed in too near on the cross section of end socket 2 portlet in end socket 2.In a word, the area of the branch pressing plate 3 by guaranteeing the most close end socket 2 large ports fully guarantees to divide the diffusion of 3 pairs of liquid of pressing plate towards end socket 2 large port directions, has further improved the uniformity that fluid pressure distributes.
As shown in Figure 3, in the described end socket 2 in fact axially spaced-apart two branch pressing plate 3A, 3B are installed.The advantage that two even more minutes pressing plates are installed is self-evident.The utility model on this basis, the average diameter that will lean on the branch pressing plate 3B of end socket 2 portlet into to go up tap hole 4 is designed to greater than leaning on the branch pressing plate 3A of end socket 2 large ports into to go up the average diameter of tap hole 4.This be because, portlet the closer to end socket 2, fluid pressure distributes more concentrated, to lean on the branch pressing plate 3B of end socket 2 portlet into to go up average diameter design bigger of tap hole 4, can reduce the resistance of the liquid flow of this minute pressing plate 3B, otherwise, the excessive transmembrane pressure that just may reduce cartridge surface of resistance, thus whole filtration system is caused adverse effect.In addition, the average diameter that goes up tap hole 4 as the branch pressing plate 3B that leans on end socket 2 portlet into is when leaning on that into the branch pressing plate 3A of end socket 2 large ports goes up the average diameter of tap hole 4, in fact make the degree of scatter of fluid pressure in the end socket 2 be the step variation, namely progressively with being evenly distributed of fluid pressure, thus can the comparison of liquid flow control is mild and stable.
Shown in Fig. 3,6, no matter several branch pressing plates 3 are installed in end socket 2, between the portlet of the branch pressing plate 3B of the most close end socket 2 portlet and this end socket 2 rectification part 5 is installed also, described rectification part 5 is to be made of at least two flow deflectors 51 that arrange vertically respectively.Point out that above the closer to the position of end socket 2 portlet, fluid pressure distributes more concentrated in the end socket 2, so in case be subjected to stopping of branch pressing plate 3B, just more easy formation turbulent flow, thereby consumable liquid kinetic energy.Therefore, the utility model makes liquid feed towards the axially-movable of end socket 2 by each flow deflector 51 that arranges vertically on the rectification part 5, reaches unified thus and flows to, and reduces the purpose of fluid energy loss.As a kind of concrete structure of rectification part 5, as shown in Figure 6, rectification part 5 is made of the flow deflector 51 that two right-angled intersections connect.
Shown in Fig. 4,5, no matter be to depend on the into branch pressing plate 3A of end socket 2 large ports, still depend on the into branch pressing plate 3B of end socket 2 portlet, on same minute pressing plate 3 equal diameters of each tap hole 4 and on this minute pressing plate 3 rectangular array, and the spacing unanimity between adjacent two tap holes 4 arbitrarily wherein.Need explanation, in Fig. 4,5, all pointed at out a tap hole 4, but those skilled in the art are readily appreciated that the intersection point of any two reference lines namely indicates the central point of a tap hole 4 among Fig. 4,5.Therefore, find out easily, tap hole 4 is carried out cloth postpone in such a manner, it is the most uniform dividing the distribution of tap hole 4 on the pressing plate 3.
As shown in Figure 3, no matter be to depend on the into branch pressing plate 3A of end socket 2 large ports, still depend on the into branch pressing plate 3B of end socket 2 portlet, these two branch pressing plates 3 all are positioned on the cross section of end socket 2, and at this moment, these two branch pressing plates 3 just equal 90 degree with the angle α of end socket 2 axis.Certainly, the cross section that these two branch pressing plates 3 also can be positioned at end socket 2 exists on other cross sections of certain angle, as long as guarantee from flowing to the large port of end socket 2 after the portlet of end socket 2 flows into the tap hole 4 that the liquid of end socket 2 can gather by this minute pressing plate 3 dispersedly.Certainly, these minutes pressing plate 3 and the angle α of end socket 2 axis be preferably in 70 degree between 90 degree.
