Abstract
The utility model relates to a single filtrating-tube hydraulic filter which is used in the oil-tank and its filter-element can be changed without stopping the machine comprising filter cover (3), dirt indicator (7), filtering cartridge (8), by-pass valve (9), filter-element (10), collecting-dirt cup (12), auto-sealing valve seat (13) and auto-sealing valve (14), etc. The invention is characterized in that a bushing filtering cartridge structure is set inside the filtering cartridge (8). In the process of changing the filter-element, the bushing filtering cartridge can make the oil inside the absorbing-oil or draining-oil filter directly flow through the filter-inlet but not through the filter-element (10) to the outlet in a non-filtrated condition. After the changing of filter element, the bushing filtering cartridge makes the oil flow through the filter-element (10) to the outlet again in a normal filtrating condition. The utility model has the advantages of that the utility model supplies an economic and convenient single filtrating-tube hydraulic filter which can change the filter-element without stopping the machine; the utility model can guarantee the filter-element (10) changing of the machine which cannot be stopped in a long time or whose stopping will lead to a serious loss. The utility model is not only provided with the function of the double filtrating-tube filter but also the handsome form, delicate volume and easy-erection structure that is the same as the single filtrating-tube filter.
Description
Technical field
The utility model relates to a kind of hydraulic filter, especially a kind of need not shut down just can carry out fuel tank that filter core changes with single filter cylinder inhale, the oil return hydraulic filter.
Background technology
Existing single filter cylinder hydraulic filter all needs can carry out filter core and changes under the state of shutting down; though existing pair of filter cylinder hydraulic filter can switch to standby filter cylinder work under non-stop-machine state; change polluting filter core; but the structure essence of two filter cylinder hydraulic filters is to add a rotary valve switch operating hydraulic fluid port in the middle of two single filter cylinder hydraulic filters; so its volume is big, complex structure is installed inconvenient; from economic angle, many reserve filters just exist certain fund to overstock.
Summary of the invention
The purpose of this utility model has been to provide a kind of fuel tank that can allow carry out switching to inlet port or the direct structure that is communicated with fuel tank of oil return opening when filter core is changed with single filter cylinder hydraulic filter, more the short time internal filter of renew cartridge is non-filtration state, after finishing, replacing can switch to the normal filtration state, filter profile is attractive in appearance simultaneously, and volume is small and exquisite.
For achieving the above object, the utility model has adopted following technical scheme:
In the filter cylinder of monotubular filter, set up a kind of nested cartridge structure, this structure can allow the oil suction filter make fluid directly flow to the non-filtration state of oil suction outlet P from the oil suction inlet P0 of oil suction filter without filter core 10 carrying out switching to when filter core is changed, and can switch to the normal filtration state that makes fluid flow to oil suction outlet P again through filter core 10 from the oil suction inlet P0 of oil suction filter and change after finishing; Equally, this structure can allow return filter make fluid directly flow to the non-filtration state of oil return outlet T0 from the oil return inlet T of return filter without filter core 10 carrying out switching to when filter core is changed, and can switch to the normal filtration state that makes fluid flow to oil return outlet T0 again through filter core 10 from the oil return inlet T of return filter and change after finishing.When the outer wall of the described nested filter cylinder inwall along filter cylinder 8, inwall is inhaled, return filter is the normal filtration state when the outer wall of collecting-dirt cup 12 is pushed into self-styled valve seat 13 places; When the outer wall of the described nested filter cylinder inwall along filter cylinder 8, inwall is inhaled, the non-filtration state when return filter is filter core to be replaced when the outer wall of collecting-dirt cup 12 is pulled to filter end back-up ring 5 places of filter cylinder 8.
Nested filter cylinder comprises: with the push rod 1 of 4 one-tenth releasable connections of bypass valve seat, be enclosed within push rod 1 outer wall and cover nut 2, the bypass valve seat 4 with 11 one-tenth releasable connections of interior filter cylinder, the interior filter cylinder 11 of 3 one-tenth releasable connections with filter.
The further improvement of such scheme is: filter cylinder 11 is sliding along filter cylinder 8 inwalls and is stopping seepage mutually of filter core both sides, back fluid in setting up sealing ring 6, make in interior filter cylinder 11 and filter cylinder 8 cooperation places; Filter cylinder 11 is sliding along collecting-dirt cup 12 outer walls and is stopping seepage mutually of filter core both sides, back fluid in setting up sealing ring 15, make in interior filter cylinder 11 and collecting-dirt cup 12 cooperation places.
Described in the utility model a kind of need not shut down just can carry out fuel tank that filter core changes with single filter cylinder inhale, the oil return hydraulic filter; have the following advantages: the monotubular hydraulic filter that it provides a kind of economy need not shut down easily again just can to carry out filter core to change, it can guarantee that some can not shut down and shut down the equipment that will cause heavy losses in long-time at non-stop-machine state renew cartridge more smoothly.It had both had the function of double-drum filter, had the structure that common monotubular filter profile is attractive in appearance, volume is small and exquisite, easy for installation again.
In addition, described in the utility model a kind of need not shut down just can carry out fuel tank that filter core changes with single filter cylinder inhale, the oil return hydraulic filter, hermetically-sealed construction is simply and easy care.
