Abstract
The utility model relates to a filter. The filter comprise a cylindrical filter body, a filter element and a filter screen, wherein a liquid outlet is arranged on one end of the filter body; a port connected with a pipe of a hydraulic system is arranged outside the liquid outlet; the other end of the filter body is fixedly connected with the filter element; a filter cavity is reserved between the filter body and the filter element; a liquid inlet is arranged on the filter element; and one end of the cylindrical filter screen is fixedly connected with the filter element. The filter is characterized in that the other end of the filter screen is arranged in the filter cavity, and the size of the outer diameter of the filter screen is matched with that of the inner diameter of the filter cavity; and a plurality of filter discs are arranged on the cylindrical filter screen. The filter has the advantages of high filter accuracy, large liquid flow rate, long service life and low manufacture cost.
Description
Technical field
The utility model relates to a kind of filter.
Background technology
Filter is very important parts in the hydraulic system, is to be used for keeping hydraulic system to clean, prevent that impurity from entering in the liquid-supplying system, and he can guarantee the normal operation of Hydraulic Elements and system.Present filter adopts the monolithic screen pack mostly, and screen pack is too fine and closely woven, and filtering traffic is little, can not satisfy jumbo hydraulic system; The aperture of the screen pack of monolithic is single in addition, if the aperture is too small, filter screen is easy to stop up, and the aperture is excessive, and then less impurity is easy to enter in the hydraulic system, damages Hydraulic Elements, and the system that influences normally moves.
The utility model content
The purpose of this utility model provides that a kind of filtering accuracy height, flow are big, the filter of long service life.
The technical solution adopted in the utility model is:
A kind of filter, comprise a cartridge filter main body, one filter core and a filter screen, one end of described filter body is provided with liquid outlet, the outside of this liquid outlet is provided with the interface that is connected with hydraulic system pipeline, the other end of described filter body is fixedlyed connected with filter core, leave filter chamber between described filter body and filter core, described filter core is provided with inlet, described filter screen is a tubular structure, one end of described filter screen is fixedlyed connected with filter core, the other end of described filter screen places in the filter chamber, and the internal diameter size of the external diameter of this filter screen size and filter chamber is complementary, and described tubular filter screen is provided with a plurality of filter discs.
The utility model places filter screen in the filter chamber, and the inboard of the outside of filter screen and filter is complementary, and liquid directly enters in the filter screen from inlet, flows out from liquid outlet behind the net filtration after filtration; In order to strengthen the filtering accuracy of filter screen, in filter screen, be provided with a plurality of filter discs.
Further, the pore size of described filter disc is reduced to the liquid outlet end step by step by the inlet end, provides the filtering accuracy and the service life of filter screen with regard to having avoided because of the filter screen that stops up not of uniform size of impurity in the liquid like this.
Further, the described end of filter screen one end in the filter chamber that places contacts with filter body, and this contact position is provided with sealing ring, filter screen directly has been communicated with inlet and liquid outlet like this, prevented that liquid from entering in the filter chamber, thereby reduced the sealing requirements between filter core and filter body, can reduce production costs effectively.
The utility model has the advantages that: filtering accuracy height, fluid flow are big, long service life, low cost of manufacture.

The specific embodiment
As shown in Figure 1, a kind of filter, comprise a cartridge filter main body 1, one filter core 2 and a tubular filter screen 3, end at filter body 1 is provided with liquid outlet 4, the outside of this liquid outlet 4 is provided with the interface 5 that is connected with hydraulic system pipeline, the other end of filter body 1 is fixedlyed connected with filter core 2, leave filter chamber 6 at filter body 1 and 2 of filter cores, on filter core 2, be provided with inlet 7, one end of filter screen 3 is fixedlyed connected with filter core 2, the other end of filter screen 3 places in the filter chamber 6, and the external diameter of this filter screen 3 size is complementary with the internal diameter size of filter chamber 6, and places the end of filter screen 3 one ends of filter chamber interior 6 to contact with filter body 1, and this contact position is provided with sealing ring 9, filter screen 3 directly has been communicated with inlet 7 and liquid outlet 4 like this, liquid can directly enter in the filter screen 3 from inlet 7, filters the back through filter screen 3 and flows out from liquid outlet 4, has avoided liquid to stay in filter chamber 6, also reduced simultaneously the sealing requirements of 1 of filter core 2 and filter body, can reduce production costs effectively; For filtering accuracy that strengthens filter screen and the flow that increases filter screen, on tubular filter screen 3, be provided with a plurality of filter discs 8, and the pore size of filter disc 8 is reduced step by step to liquid outlet 4 ends by inlet 7 ends.
Claims (3)
