Processing technology is simpler, suitable for a large amount of productions.
The present invention is achieved through the following technical solutions：
Filter with efficient filter core, including valve body, are provided with fluid intake and fluid issuing in valve body, fluid intake and
Runner is formed between fluid issuing, valve body is provided with a filtering mouth, filters and be provided with filter core at mouth, the filter core enters positioned at fluid
Between mouth and fluid issuing, the filter core includes the internal layer filter cylinder and outer layer filter cylinder of bottom end opening, internal layer filter cylinder and outer layer filter cylinder
For cylinder with holes, the side of filter core is connected with fluid intake, and the bottom end opening of filter core is connected with fluid issuing, the filtering
Mouthful top is provided with bonnet, is arranged with valve cap nut outside bonnet, and the aperture in hole is more than the hole in hole on internal layer filter cylinder on outer layer filter cylinder
Footpath, the hole count in hole is less than the hole count in hole on internal layer filter cylinder on outer layer filter cylinder.
The filter of the present invention, using double-deck filter cartridge type filter core simultaneously, it is possible to increase the filtering accuracy of fluid ring, leak
Point is few, improves the security of filtering, avoids fluid from leaking, simpler compared to conventional filter, processing technology, is applied to
A large amount of productions.The fluid for needing to filter is entered in valve body by fluid intake, after the side filtering of filter core, passes through filter core bottom
Then end is flowed out from fluid issuing, wherein bonnet ensure that fluid will not be to filter External leakage, outer layer filter with valve cap nut
Cylinder not filtration, mainly plays a supportive role to internal layer filter cylinder, while carries out sealing function to valve body；Internal layer filter cylinder carries
Filtration, supported by outer layer filter cylinder with holes, greatly improve filter effect, while ensure that the sealing of whole valve body
Energy.
Spring is provided between the top surface of the bonnet and filter core, can ensure to keep sealing between filter core and valve body.
It is fixedly connected between internal layer filter cylinder and outer layer filter cylinder using pressure welding, avoids rotating between each other, only simultaneously
Leakage point at pressure welding be present, for traditional filter screen, leakage point is few, and reliability is high.
Metallic sealing section is provided between the bottom of filter core and the intraoral wall of filtering, improves the sealing between valve body and filter core.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention has the filter of efficient filter core, using double-deck filter cartridge type filter core, it is possible to increase the mistake of fluid ring
Precision is filtered, while leakage point is few, improves the security of filtering, avoids fluid from leaking, compared to conventional filter, processing technology
It is simpler, suitable for a large amount of productions；
2nd, the present invention has the filter of efficient filter core, and spring, Neng Goubao are provided between the top surface of the bonnet and filter core
Demonstrate,prove and keep sealing between filter core and valve body, metallic sealing section is provided between the bottom of filter core and the intraoral wall of filtering, improve valve body and
Sealing between filter core；
3rd, the present invention has the filter of efficient filter core, is fixedly connected between internal layer filter cylinder and outer layer filter cylinder using pressure welding,
Avoid rotating between each other, while leakage point at pressure welding only be present, for traditional filter screen, leakage point is few,
Reliability is high.
