Description

Accurate filter

Technical field

This utility model is accurate filter, belongs to water treatment field.

Background technology

The filter element of existing accurate filter mostly uses center-pole to support the fixing mode of increased pressure board and fixes filter element, shell even Connecing and use ring flange and the sealing means of clamp connection, its shortcoming is that shell connector is relatively big, and the sealing ring of connector can be because of many Secondary dismounting and fatigue deformation, easily cause and leak or shortcoming that water pressure resistance reduces, and the work complexity changing filter element is loaded down with trivial details.

Summary of the invention

This utility model is the shortcoming for above-mentioned existing accurate filter, and innovation and creation go out the essence of a kind of new structure Close filter, the most only need to open a manual operations hole, just the filter element in filter can be carried out dismounting and change work.Behaviour Making hole and operation port lid can dock with screw thread, sealing ring relatively I is born and is repeatedly detached without deformation, compared with prior art Sealing property more firmly, more resistant to high pressure, manual operations is convenient, save material cost, improve the whole of accurate filter Weight.The present utility model content is as follows: a kind of accurate filter, it is characterised in that including: filter housing (1), behaviour Make hole (2), operation port lid (3), air bleeding valve (4), water inlet (5), water sampling mouth (6), outlet (7), nut (8), screw rod (9), cushion rubber (10), filter element end socket (11), filter element (12), positioning pipe (13), rubber cushion (14), dividing plate (15), upper storehouse (16), lower storehouse (17), described handle hole (2) is located at filter housing (1) upper end, operates the screw thread of port lid (3) with the screw thread of handle hole (2) Compact siro spinning technology, air bleeding valve (4) are located in operation port lid (3), the inside of described filter housing (1) be divided into storehouse (16) and under Storehouse (17) dividing plate (15) is spaced, positioning pipe (13) is located on dividing plate (15), and the device making water purification passage and filter element (12) is fixed Position device, water inlet (5) is located on the position of filter housing (1), upper storehouse (16), and water sampling mouth (6), outlet (7) were located at On filter shell (1), lower storehouse (17) corresponding position, it is upper, nut (8) that described nut (8) is welded on filter housing (1) Screw central shaft aligns in line with the central shaft of positioning pipe (13), and rubber cushion (14) is contained on positioning pipe (13), filter element (12) Lower end be contained in that rubber cushion (14) is upper, filter element end socket (11) is contained in the upper end of filter element (12), cushion rubber (10) is placed on screw rod (9) and spiral shell Female joint portion of (8), the lower end of screw rod (9) withstand on filter element end socket (11).Its work process and operation principle be: is installing filter During core, first turn on operation port lid (3), then rubber cushion (14) is contained on positioning pipe (13), then the lower end of filter element (12) is contained in Filter element end socket (11) being contained in the upper end of filter element (12) on rubber cushion (14), cushion rubber (10) is placed on screw rod (9) and the knot of nut (8) again Conjunction portion, the lower end of screw rod (9) withstands on filter element end socket (11), then screw rod (9) is tightened, after filter element installs, load onto handle hole Lid (3), completes installment work.During work, current flow to the position in storehouse (16), water in filter housing (1) from water inlet (5) Flow through filter element (12) to filter, flow to the position of lower storehouse (17), flow out from outlet (7).

Accompanying drawing explanation

Figure of description is overall structure figure of the present utility model: filter housing (1), handle hole (2), operation port lid (3), air bleeding valve (4), water inlet (5), water sampling mouth (6), outlet (7), nut (8), screw rod (9), cushion rubber (10), filter element envelope Head (11), filter element (12), positioning pipe (13), rubber cushion (14), dividing plate (15), upper storehouse (16), lower storehouse (17).

Detailed description of the invention

Filter housing of the present utility model, handle hole, operation port lid, filter element end socket, dividing plate, positioning pipe can use 304 Number stainless steel, cleaved, weld, polish, polish, the operation such as deoil is made, air bleeding valve, nut, screw rod use 304 Number stainless steel can commercially be chosen.The most each parts are connected with each other just can implement this utility model very well.
