Abstract
The utility model discloses a filter which comprises a core body, a by-pass valve, a core body end cover and a by-pass valve end cover, wherein connecting end covers of the core body and the by-pass valve, namely the core body end cover and the by-pass valve end cover, are of a split type combination structure, an annular body is arranged at one end of the core body, two co-axial and protruding annular bodies are arranged at the left end of the by-pass valve end cover, threads arranged on the outer circumferential surface of the outer annular body of the by-pass valve end cover are matched with threads arranged on the inner circumferential surface of the annular body at the end of the core body, a sealing gasket is arranged between the core body end cover and the by-pass valve end cover, a filter element is arranged on the by-pass valve, and one end of the filter element is inserted and fixed between a groove formed between the two annular bodies at the left end of the by-pass valve end cover. The filter is used for separation between liquid and particulate matter.
Description
Technical field:
The utility model relates to a kind of stripping technique, particularly hydraulic oil filter.
Background technique:
Be provided with bypass valve in the existing hydraulic oil return filter, its objective is that filter core when filter stops up makes hydraulic oil get back to fuel tank by bypass valve when serious, bypass valve end cap and end cover of filter element are structure as a whole, when renew cartridge more, need change simultaneously the bypass valve end cap, increase the working service cost, in addition, because filter core stops up serious bypass valve and is opened, hydraulic oil is directly got back to fuel tank, and the particulate matter in the oil can cause the hydraulic parts damage.
The model utility content:
The utility model purpose provides the low a kind of filter of a kind of more renew cartridge expense.
Another purpose of the present utility model is to stop up seriously through bypass valve at filter core to get back to a kind of filter that does not damage hydraulic system in the fuel tank.
The technological scheme that realizes the utility model purpose is that a kind of filter comprises core body, bypass valve and end cap thereof, it is characterized in that: core body is connected the connection end cap with bypass valve be that the core body end cap is the split type structure that combines with the bypass valve end cap.Described core body end cap is that the split type structure that combines is with the bypass valve end cap, there is a ring body core body termination, the left end of bypass valve end cap has the ring body of two coaxial evaginations, wherein the screw thread that is provided with on screw thread and the core body termination ring body inner peripheral surface of the outer circumferential face of outer ring body matches, and is provided with sealing gasket between core body end cap and bypass valve end cap.The core body end cap is that the split type structure that combines is with the bypass valve end cap, the core body termination is provided with a ring body, the left end of bypass valve end cap is provided with the coaxial ring body of two evaginations, outer ring body wherein places the ring body hole of described core body termination, is provided with sealing gasket between described bypass valve end cap and core body end face.Described bypass valve is provided with a filter core, pegs graft and be fixed in the groove between two ring bodies of described bypass valve end cap left end in the termination of this filter core.
The utility model has advantages of that compared with the prior art maintenance cost is low and does not damage hydraulic system.
Description of drawings:
Fig. 1 is a kind of structural representation of the utility model filter; Fig. 2 is the another kind of structural representation of filter.
Embodiment:
For the core body end cap and the bypass valve end cap that overcome existing filter is inseparable integrally-built defective, adopt the split type structure that combines, now provide the embodiment of following two concrete split combinations:
1, core body 6 terminations have a ring body 3 to be the core body end cap, its outer circumferential face is connected by glue-line with the inner peripheral surface of core body termination, the left end of bypass valve end cap 1 has the ring body of two coaxial evaginations, wherein the screw thread that is provided with on the ring body inner peripheral surface of screw thread and core body termination of the outer circumferential face of outer ring body matches, and is provided with sealing gasket 2 between core body end cap and bypass valve end cap 1.The structure of by-pass valve body 4, interior turnbuckle and stage clip 5 is not done change (referring to Fig. 1).
2, core body 6 terminations are provided with a ring body 3 formation core body end caps, the left end of bypass valve end cap 1 is provided with the coaxial ring body of two evaginations, outer ring body wherein places the hole of the ring body of described core body termination, between described bypass valve end cap and core body end face, be provided with sealing gasket 8, and bolt, stage clip 5 in the by-pass valve body are not changed.
For solve existing plugged filter when serious hydraulic oil directly get back to the problem that causes hydraulic system impaired in the fuel tank by bypass valve 4 without filtration.Install a filter core 7 additional at bypass valve, the termination of this filter core is inserted in the circular groove between the ring body of two evaginations of bypass valve end cap left end, connects with glue.This bypass valve with filter core, when the filter filter core stops up when serious, this filter core can filter out the large particle in the oil at least, avoids before renew cartridge more the hydraulic system injury.
The assembling of above-described embodiment and dismounting are also very convenient, the scheme that double thread connects, and only need twist off the bypass valve end cap is replaceable filter core; For embodiment 2 plug in structure, only need to extract the bypass valve end cap out filter core is separated with the bypass valve end cap.The bypass valve end cap does not need to change maintenance cost saving.
Claims (4)
1. a filter comprises core body, bypass valve and end cap thereof, it is characterized in that: core body is connected the connection end cap with bypass valve be that the core body end cap is the split type structure that combines with the bypass valve end cap.
2. a kind of filter according to claim 1, it is characterized in that: described core body end cap is that the split type structure that combines is with the bypass valve end cap, there is a ring body core body termination, the left end of bypass valve end cap has the ring body of two coaxial evaginations, wherein the screw thread that is provided with on screw thread and the core body termination ring body inner peripheral surface of the outer circumferential face of outer ring body matches, and is provided with sealing gasket between core body end cap and bypass valve end cap.
3. a kind of filter according to claim 1, it is characterized in that: the core body end cap is that the split type structure that combines is with the bypass valve end cap, the core body termination is provided with a ring body, the left end of bypass valve end cap is provided with the coaxial ring body of two evaginations, outer ring body wherein places the ring body hole of described core body termination, is provided with sealing gasket between described bypass valve end cap and core body end face.
