Detailed description of the invention
The exemplary embodiments embodying the utility model feature & benefits will describe in detail in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from scope of the present utility model, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the utility model.
The utility model embodiment provides a kind of filter, and filter of the present utility model has reverse osmosis membrane filter element of the present utility model, and reverse osmosis membrane filter element of the present utility model is applied to filter.
The reverse osmosis membrane filter element 1 of the utility model embodiment as depicted in figs. 1 and 2, comprises filtering body 10.This filtering body 10 can be tubular structure, and inside is provided with the material 11 of water treatment.As shown in Figure 1, reverse osmosis membrane filter element 1 includes intake tunnel 101, water purification path 10 2 and condensed water path 10 3.Need the water carrying out processing to enter in filtering body 10 by intake tunnel 101, after the process of material 11, form water purification part and condensed water part, water purification is flowed out by water purification path 10 2, and condensed water is flowed out by condensed water path 10 3.
Each different reverse osmosis membrane filter element needs the flow proportional determining water purification and condensed water according to actual conditions, to control the water treatment pressure of reverse osmosis membrane, and then forms the water purification of different disposal level.In the utility model, condensed water path 10 3 is provided with the pressurized construction of limited flow, to regulate the flow proportional of water purification and condensed water.This pressurized construction can be controlled, as choke valve, also can determine, such as determine the hole of flow.
In preferred embodiment of the present utility model, pressurized construction is metering orifice 12, and metering orifice 12 regulates condensed water water yield.In the preferred embodiment, condensed water path 10 3 is arranged a baffle plate 120, baffle plate 120 is arranged metering orifice 12, and metering orifice 12 is arranged near the outlet of condensed water passage.In addition, metering orifice 12 can be circular hole, and also can be rectangular gap, as long as can meet flow and pressure requirements, concrete shape be determined according to actual needs.
In preferred embodiment of the present utility model, water purification path 10 2 is provided with an elastomer block 13, this elastomer block 13 can play the effect of check valve.When in water purification path 10 2, water purification flows out, elastomer block 13 becomes to water purification path 10 2 Way out generation bullet under hydrostatic pressure, conducting water purification path 10 2, makes water purification flow out reverse osmosis membrane filter element 1.When reverse osmosis membrane filter element 1 external water stream is for entering filter reverse osmosis membrane filter element 1 inside along water purification path 10 2, elastomer block 13 closes water purification path 10 2 under outside water flow pressure, prevents external water stream from entering reverse osmosis membrane filter element 1.
Can realize the unidirectional control of water purification path 10 2 in this preferred embodiment by means of only an elastomer block 13, and need not arrange check valve, structure is simple, reliable in action.The setting of this elastomer block 13 can be arranged according to actual needs.
As shown in Figures 2 and 3, the material of elastomer block 13 is soft material to the concrete structure of this preferred embodiment.Water purification path 10 2 is communicated with and is provided with guiding joint 14, guiding joint 14 has a planar end surface 141 near water purification path 10 2 exporter.And elastomer block 13 comprises support portion 131 and elasticity ring portion 132.Wherein, support portion 131 is fixedly installed on the support 15 of water purification path 10 2, and this support 15 is a part for the housing of reverse osmosis membrane filter element 1.Elasticity ring portion 132 is laminated structure, is looped around support portion 131 on one end of guiding joint 14, and elasticity ring portion 132 reclines the planar end surface 141 of guiding joint 14 near water purification channel outlet.Elasticity ring portion 132 side is inserted in housing 16 and fixes, and opposite side suspends, and becomes elastic change part.
As shown in Figure 3, in water purification path 10 2, water purification as shown by arrows in FIG. direction flows out, and deform at the elastic change part flowing out elasticity ring portion 132 under water pressure, and produce gap between the planar end surface 141 of guiding joint 14, water purification flows out from this gap.When external water stream is for entering reverse osmosis membrane filter element 1 inside along water purification path 10 2, the elastic change part of water impact elasticity ring portion 132, top this elastic change part of pressure is with the planar end surface 141 of the guiding joint 14 that reclines, hermetically-sealed construction is formed between this elastic change part and planar end surface 141, thus disconnect water purification path 10 2, prevent external water stream from entering reverse osmosis membrane filter element 1 along water purification path 10 2.
The beneficial effects of the utility model are, the utility model compared with prior art, divide by means of only the elastic change part of elastomer block 13 in the utility model and coordinate with water purification path 10 2, water (flow) direction unification in water purification path 10 2 can be realized, structure is simple, it is little to take up room, filter overall volume is reduced, accords with the demands of the market, can the competitiveness of product in market be improved.
The technical solution of the utility model is disclosed as above by preferred embodiment.The change that those skilled in the art do when should recognize the scope and spirit of the present utility model disclosed in the claim do not departed from appended by the utility model and retouching, within the protection domain all belonging to claim of the present utility model.
