Description

Through type dual flow filter

Technical field

The utility model is related to a kind of filter, more particularly to a kind of through type dual flow filter.

Background technology

With the development of technology, filter is gradually applied to industry-by-industry, generally can all be used in the pipeline of liquid conveying To filter, filter is that the greasy dirt filtering in liquid is clean, cleans dirt, but many filters all only can be used in In the pipeline of unidirectional stream, during if necessary to reverse flow, then many peace filters are needed again, gradually, currently on the market also Have a filter of reversible, but it is unclean to there is filtering, or it is poorly sealed real the problems such as, when using, due in pipeline Pressure difference, causes filter to use unstable, and effect is bad.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, it is to avoid filter can only be used unidirectionally, Huo Zheyou The problems such as differential filter effect is bad, and a kind of through type dual flow filter is provided, the utility model can be used with two-way, May be mounted at liquid flow path direction frequently commutation original paper pipeline in, it is easy to use, quick.

The purpose of this utility model is achieved by the following measures：A kind of through type dual flow filter, including housing, Described housing two ends are separately installed with end cap, and described housing constitutes cavity, divides in two end cap in described cavity with end cap By-passing valve is not installed, the described by-passing valve other end is provided with inner end cap, and described inner end cap forms first passage with end cap, Being socketed with described inner end cap can prolong the slip pipe that inner end cap horizontally slips, and described slip pipe is provided with for balancing the flat of pressure Weighing apparatus hole, is provided with filter core in described slip pipe, and inner end cap is socketed on filter core, has space to form second between slip pipe and filter core Passage, is provided with cavity and forms third channel in described filter core.

Preferably, described end cap is provided with screw thread, and end cap is threadedly secured on housing.

Preferably, the O-ring for sealing is provided between described end cap and housing.

Preferably, the internal diameter of described slip pipe and the external diameter of inner end cap are equal.

Preferably, it is provided with O-ring between described slip pipe and inner end cap.

Preferably, the external diameter of described filter core is not more than the internal diameter of inner end cap.

Preferably, it is provided with O-ring between described filter core and inner end cap.

The beneficial effects of the utility model are：The utility model simple structure, it is easy to use, and the conjunction of each structure design Reason, multiple O-rings can by the more preferably tight of whole filter seal, will not leakage body, the design of slip pipe makes whole filter Pressure difference is more preferably reasonably avoided, in the presence of pressure difference, slip pipe can be slided, open filtration channel, complete filtering, balance pipe balance Pressure difference, whole filter is durable.

Specific embodiment

In order to deepen to understanding of the present utility model, further is made to the utility model below in conjunction with embodiment and accompanying drawing Describe in detail.

Embodiment 1：As shown in figure 1, a kind of through type dual flow filter, including housing 1, housing two ends are separately installed with end Lid 2, is provided with the O-ring 11 for sealing between end cap and housing, end cap is provided with screw thread, and end cap is threadedly secured to housing On, housing constitutes cavity with end cap, is separately installed with by-passing valve 3 in cavity in two end cap, and the by-passing valve other end is provided with the inner Lid 4, inner end cap and end cap form first passage 5, and being socketed with inner end cap can prolong the slip pipe 6 that inner end cap horizontally slips, slip pipe with O-ring is provided between inner end cap, the internal diameter of slip pipe is equal with the external diameter of inner end cap, and slip pipe is provided with the balance for balancing pressure Hole 7, is provided with filter core 8 in slip pipe, and inner end cap is socketed on filter core, O-ring is provided between filter core and inner end cap, outside filter core Footpath is not more than the internal diameter of inner end cap, has space to form second channel 9 between slip pipe and filter core, cavity is provided with filter core and forms the 3rd Passage 10.

As shown in Figure 2 and Figure 3, when fluid is by by-passing valve, first passage is flowed through, in the presence of pressure differential, slip pipe can be former Reason import, to another Slideslip can now open second channel, and liquid can flow to second channel from above, realize liquid from the Two passages enter into the third channel of inner side by filter core, complete filtration, and slip pipe is provided with balance pipe, can be in slip pipe Outside forms too big pressure difference, prevents slip pipe from deforming under the effect of the pressure；And many places are provided with O-ring, can entirely Channel enclosed it is more tight, prevent fluid from leaking outside, fluid communicates to be formed be provided with pressure difference, this structure before and after more preventing filtering Two by-passing valves, realize two-way flow, more effectively filter dirt.
