Detailed Description
The technical features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in the figure, the utility model relates to a Y-shaped filter for pipelines, which comprises a filter cylinder assembly and a Y-shaped filter pipe body 1, wherein the Y-shaped three ends of the filter pipe body 1 are respectively a water inlet end 2, a water outlet end 3 and a filtering end 4; the filter cartridge assembly comprises an end connecting ring 5, a filter cartridge 6 and a sealing end cover 7, wherein the connecting ring 5 and the sealing end cover 7 are respectively arranged at two ends of the filter cartridge 6 and are connected with the filter cartridge 6; the filter cartridge assembly is inserted into the filter tube body 1 from the filter end 4, and a sealing end cover 7 of the filter cartridge assembly is sealed and fixed with an opening at the end part of the filter end 4; a mounting ring 8 matched with the connecting ring 5 is arranged inside the water inlet end 2 of the filter pipe body 1; the connecting ring 5 is sleeved in the mounting ring 8 and is in threaded connection with the mounting ring 8. An observation hole 9 is respectively arranged on the water inlet end 2 and the water outlet end 3, and the observation hole 9 is sealed as a plug through a hexagon bolt.
One of cartridge filter 6 in inserting filter body 1 has served and has set up go-between 5 and the 8 threaded connection of the inside collar of the installation of end 2 of intaking, connect fixedly the one end of cartridge filter 6 grafting in filter body 1 through this kind of form, improved the firm in connection degree of cartridge filter 6 in filter body 1. And because the one end of cartridge filter 6 grafting in filter body 1 is fixed, has improved the resistance to deformation ability of the cartridge filter 6 tip, prevents to appear the gap between the tip of cartridge filter 6 and the filter body 1 inner wall.
In this embodiment, the filter cartridge 6 can be rolled into a cylinder by using a stainless steel mesh or rolled into a cylinder by using a stainless steel perforated plate, and the end connection ring 5 and the end cover 7 can be welded and fixed at two ends of the filter cartridge 6, but the replacement cost is high due to the integrally formed arrangement.
Example 2
This example differs from example 1 in that:
the surface of the sealing end cover 7 is provided with an annular fixed outer ring 10 and an annular fixed inner ring 11, the fixed inner ring 11 is arranged in the fixed outer ring 10 and is coaxial with the fixed outer ring 10, an annular insertion groove is formed between the fixed outer ring 10 and the fixed inner ring 11, the end part of the filter cartridge 6 is inserted in the insertion groove, and the end part of the filter cartridge 6 is sealed with the insertion groove through a rubber ring.
The filter cartridge 6 is the most vulnerable component of the Y-filter and in the past, if the filter cartridge 6 becomes damaged, the filter cartridge 6 would need to be replaced along with the end cap 7. In the technical scheme of this application, the tip of cartridge filter 6 is pegged graft in the inserting groove that forms between fixed outer loop 10 and fixed inner ring 11 for but separation set up between cartridge filter 6 and end cover 7, can change cartridge filter 6 alone after cartridge filter 6 damages, reduce and change the maintenance cost.
The filter cartridge assembly further includes a pull rod 12; a middle threaded sleeve 13 is arranged in the connecting ring 5, a plurality of fixing rods 14 are arranged between the middle threaded sleeve 13 and the annular inner wall of the connecting ring 5, and two ends of each fixing rod 14 are respectively fixedly connected with the middle threaded sleeve 13 and the connecting ring 5; one end of the pull rod 12 penetrates through the sealing end cover 7 and is fixed with the sealing end cover 7 through a bolt, and the other end of the pull rod 12 is sleeved in the middle threaded sleeve 13 and is in threaded connection with the middle threaded sleeve 13.
Because the tip at cartridge filter 6 has set up the go-between, if set up go-between 5 and cartridge filter 6 integrated into one piece or set up both welded fastening, not only increased cartridge filter 6's manufacturing cost, need change in the lump together with go-between 5 after cartridge filter 6 damages moreover, the maintenance cost in later stage is higher. The filter cartridge 6 is fixed between the connecting ring 5 and the end cap 7 by tightening and fixing the connecting ring 5 and the end cap 7 through the pull rod 12. All be separable setting between cartridge filter 6, go-between 5, the end cover 7 three, can change one of them alone after damaging, and need not wholly change the cartridge filter subassembly, under the circumstances of the joint strength who guarantees between cartridge filter 6 and the filter tube body 1, reduce and change the maintenance cost.
An annular step surface is arranged in the connecting ring 5, an annular bending edge 61 is arranged at one end of the filter cartridge 6 and is inserted into the connecting ring 5, and the bending edge 61 is attached to the annular step surface in the connecting ring 5.
A fixed pressure ring assembly is arranged on the pull rod 12; the fixed pressure ring assembly comprises a second threaded sleeve 15, a fixed pressure ring 16 and a plurality of connecting rods 17, two ends of each connecting rod 17 are fixedly connected with the inner surface of the second threaded sleeve 15 and the outer surface of the fixed pressure ring 16 respectively, and a bent edge 61 is arranged between the fixed pressure ring 16 and an annular step surface in the connecting ring 5 and is attached to the fixed pressure ring and the annular step surface; the second threaded sleeve 15 is sleeved on the pull rod 12 and is in threaded connection with the pull rod 12.
The end part of the filter cartridge 6 is provided with a bending edge 61, so that the deformation resistance of the end part of the filter cartridge 6 is improved. The edge 61 of will bending is pressed on the annular step face in the go-between 5 through fixed clamping ring subassembly for the fixed firmness of the tip of cartridge filter 6 is higher, and through annular step face, fixed clamping ring 16 to the centre gripping of the edge 61 of bending, make the resistance to deformation intensity of the tip of cartridge filter 6 further improve, guarantee the filter effect of filter.
Compared with the scheme of welding and fixing the end connecting ring 5 and the end cover 7 to two ends of the filter cylinder 6 in the embodiment 1, the scheme of the embodiment has a relatively complex structure, but the scheme of the embodiment sets the end connecting ring 5, the filter cylinder 6 and the end cover 7 to be detachable, only one part of the end connecting ring 5, the filter cylinder 6 and the end cover 7 needs to be replaced in the later maintenance process, and the maintenance cost is reduced.
However, the three end connecting rings 5, the filter cartridges 6 and the end caps 7 are detachably arranged, so that the fixing property and strength of the end of the filter cartridge 6 inserted into the filter tube body 1 are reduced, and therefore, in the embodiment, the bending edges 61 are arranged at the ends of the filter cartridges 6 to increase the deformation resistance of the ends of the filter cartridges 6. In order to increase the connection strength between the filter cartridge 6 and the connection ring 5, the annular step surface of the bending edge 61 in the connection ring 5 is pressed by the fixed pressing ring 16, so that the end part of the filter cartridge 6 is prevented from being separated from the connection ring 5 after receiving impact, and the service life is prolonged.
The fixed outer ring 10 is inserted into the opening at the end part of the filtering end 4 and is in threaded connection with the inner wall of the opening at the end part of the filtering end 4.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications, additions and substitutions within the spirit and scope of the present invention.
