Description
Technical field
The utility model relates to the clean water treatment field, in particular to a kind of end cap fixed structure and comprise the duct type ultrafiltration water purifier of this structure.
Background technology
Duct type ultrafiltration water purifier is applied in the domestic running water system, can filter out most harmful substances such as silt in the running water, iron rust, colloid, algae, bacterium.Duct type ultrafiltration water purifier generally is applied to the first order or the second level of water cleaning systems, is the main barrier of family expenses water cleaning systems.Owing to booty all accumulates,, also need more renew cartridge after use a period of time so filter core needs often flushing cleaning in filter core.Tap water supply system is different because of city, region, and it is low that hydraulic pressure has height to have, and the city tap-water supply channel is very complicated, therefore requires the end syndeton of duct type ultrafiltration water purifier reliable and stable.
At present, what duct type ultrafiltration water purifier was commonly used is stainless steel cylinder, and the fixed structure of end cap generally has two kinds: first kind is Welding Structure, and second kind is buckle structure.
Welding Structure mainly contains two kinds: first kind is that the female stainless steel ring of car is welded on the stainless steel cylinder; On corrosion resistant plate, weld a joint that is connected with end cap seal again; Joint is to have seal groove on one side; Be used for being connected with end cap seal, another side is an external screw thread, is used for being connected with tap water pipe line; Adopt external screw thread nut briquetting and stainless steel ring to screw again and compress, end face seal is adopted in sealing.Second kind is that the steel flange slot welding is connected on the stainless steel cylinder, adorns a rectangular seal in the groove, a punch forming, the end that has a flange is encapsulated on the stainless flange groove again, uses bolt to link together, and seal form is end face seal.Adopt Welding Structure, weld seam to need polishing, workload is big, and it is lack of penetration and cause leaking weld seam to occur.End face seal often is out of shape owing to pressing plate or flatness causes the decrement of sealing ring to be leaked inadequately inadequately.
The buckle-type structure mainly contains two kinds: first kind is inner blocking type, is about to the stainless steel cylinder two ends and carries out jumping-up formation groove near the part of end face, uses corrosion resistant plate to embed in the groove, with screw corrosion resistant plate is fixed on the end cap again.Second kind is exterior buckle type, is about to the stainless steel cylinder two ends near the end face part outward flanging, forms flange ring; Again with a drawing and forming; The centre has been welded the steel flange cover of a joint and has been put into stainless steel cylinder, one side joint is to have seal groove, is used for being connected with end cap seal; Another side is an external screw thread, is used for being connected with tap water pipe line; The stainless steel retainer ring that re-uses bending is enclosed within the steel flange cover on the flange ring of stainless steel cylinder, utilizes the plastic cement base that the stainless steel clamp is located at last.Will with the hands help after loading onto stainless steel retainer ring, otherwise stainless steel retainer ring will drop in this mode location, fixing not in the assembling process of stainless steel retainer ring.When holding up stainless steel retainer ring, be inconvenient to put the plastic cement base again, the plastic cement base often occurs and also do not install to the position, the displacement that comes off of part stainless steel retainer ring is just arranged, cause plastic cement base dress not get on.Because the plastic cement base is not located at periphery, also to adjust the orientation of base after assembling in addition.Therefore traditional exterior buckle type structure assembling is inconvenient, possibly need two people's coordinating operations.
