Abstract
The utility model relates to a double-cylinder filter which comprises a first filter, a second filter and a reversing valve, wherein the first filter and the second filter are connected through a pipeline; the reversing valve is used for connecting the first and second filters; the first filter and the second filter are connected through upper and lower pipelines; an oil inlet and an oil outlet are respectively formed in the middle of the upper and lower pipelines; the reversing valve is composed of an oil inlet reversing valve and an oil outlet reversing valve which are provided with equidirectional connected structures; and the oil inlet reversing valve and the oil outlet reversing valve are respectively mounted at the oil inlet and the oil outlet. The double-cylinder filter has the beneficial effects that: 1) a filter element can be exchanged without influence on the normal running of a hydraulic system; 2) the pressure at the oil inlet of the double-cylinder filter can be monitored and the safety of the double-cylinder filter is increased; and 3) the structure is simple and the manufacturing cost is low.
Description
Technical field
This model utility relates to a kind of filter, particularly a kind of duplex filter that in the fluid filter process, can switch each other.
Background technique
Fluid in the various kinds of equipment is mainly used in lubricated and cooling, but system element wearing and tearing in use can produce metallic dust and Sealing can be produced rubber impurity.These metallic dusts and rubber impurity are sneaked in the fluid, make the lubricated and cooling effect of fluid reduce, so fluid need constantly filter in recycling process.But a lot of equipment need long-term continuous operation; Therefore corresponding hydraulic system also needs long-term thereupon continuous operation; Filter uses the filter core in a period of time after-filter to be stopped up by various impurity in hydraulic system, therefore just need change or clean the filter core in the filter according to the situation of plugged filter.Common filter is under non-stop-machine situation, to change by the filter core to filter at present.
The model utility content
The model utility purpose: the purpose of the utility model provides a kind of duplex filter that can under the not out-of-work situation of hydraulic system, safeguard filter.
Technological scheme: a kind of duplex filter; Comprise first filter, second filter and the selector valve that is connected said first and second filter that connect through pipeline; Said first filter is connected through upper and lower pipeline with second filter; Be respectively equipped with filler opening and oil outlet in the middle of the upper and lower pipeline; Said selector valve is made up of oil-feed selector valve and fuel-displaced selector valve, and said oil-feed selector valve and fuel-displaced selector valve are linkage structure in the same way, and said oil-feed selector valve and fuel-displaced selector valve are installed on said filler opening and oil outlet place respectively.Said duplex filter is connected in the hydraulic system, and fluid gets into filter from filler opening, gets into first or second filter through the oil-feed selector valve, flows out this duplex filter through fuel-displaced selector valve from oil outlet through the fluid that filters.Filter core in this filter uses a period of time after-filter is stopped up by impurity, and the pressure of filler opening raises, and explaining needs to have changed the filter core in the filter.Reversing valve operated oil-feed selector valve and fuel-displaced selector valve move the switching that realizes first and second filter simultaneously; Fluid gets into another filter and filters, and can not influence this moment under the situation of hydraulic work system the filter core of the filter of previous use is changed.
Also comprise the bypass valve that connects said filler opening and oil outlet pipelines on two sides respectively.The proper functioning of when reversing valve operated switch filtering device, avoiding influencing hydraulic system need be connected bypass valve respectively in filler opening and oil outlet pipelines on two sides, open bypass valve before the switching earlier, switches to close bypass valve again after accomplishing.
Also comprise pressure transducer that is positioned at the filler opening place and the warning device that receives pressure sensor signal.In order to prevent that filter core from stop up damaging filter, at the filler opening of this duplex filter pressure transducer is set, warning device warning reminding user renew cartridge more when force value reaches the warning device setting value.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: 1, can under the situation that does not influence the hydraulic system proper functioning, change filter element; 2, can monitor the pressure of filter filler opening, improve the Security of this pair hole filter; 3, simple in structure, low cost of manufacture.

Fig. 2 is the plan view of the utility model;
Fig. 3 is the utility model control principle figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure; A kind of duplex filter; Comprise first filter 1, second filter 2 and the selector valve 3 that is connected said first and second filter 1,2 that connect through pipeline; Said first filter 1 is connected through upper and lower pipeline 4,5 with second filter 2, is respectively equipped with filler opening 6 and oil outlet 7 in the middle of the upper and lower pipeline 4,5, and said selector valve 3 is made up of oil-feed selector valve 31 and fuel-displaced selector valve 32; Said oil-feed selector valve 31 and fuel-displaced selector valve 32 are linkage structure in the same way, and said oil-feed selector valve 31 is installed on said filler opening 6 and oil outlet 7 places respectively with fuel-displaced selector valve 32.Said duplex filter is connected in the hydraulic system, and fluid gets into filter from filler opening 6, gets into first filter 1 or second filter 2 through oil-feed selector valve 31, flows out this duplex filter through fuel-displaced selector valve 32 from oil outlet 7 through the fluid that filters.Filter core in this filter uses a period of time after-filter is stopped up by impurity, and the pressure of filler opening 6 raises, and explaining needs to have changed the filter core in the filter.Reversing valve operated 3 o'clock oil-feed selector valves 31 and fuel-displaced selector valve 32 moves the switching of realization first filter 1, second filter 2 simultaneously; Fluid gets into another filter and filters, and can not influence this moment under the situation of hydraulic work system the filter core of the filter of previous use is changed.
The proper functioning of when reversing valve operated 3 switch filtering devices, avoiding influencing hydraulic system need be connected bypass valve 8 respectively in filler opening 6 and oil outlet 7 pipelines on two sides, open bypass valve 8 before the switching earlier, switches to close bypass valve 8 again after accomplishing.
In order to prevent that filter core from stop up damaging filter, at the filler opening 6 of this duplex filter pressure transducer 9 is set, warning device warning reminding user renew cartridge more when force value reaches warning device 10 setting values.
