Abstract
A double-cartridge filter comprises a first filter, a second filter and a reversing valve, wherein the first filter and the second filter are connected through pipelines including an upper pipeline and a lower pipeline, the reversing valve is connected with the first filter and the second filter, the upper pipeline and the lower pipeline are respectively provided with an oil inlet and an oil outlet in the middle, and the reversing valve consists of an oil inlet reversing valve and an oil outlet reversing valve which are of same-direction connection structures and are mounted at the oil inlet and the oil outlet respectively. The double-cartridge filter has the advantages that a filter element of the filter can be replaced without affecting normal working of a hydraulic system; pressure of the oil inlet of the filter can be monitored, safety of the double-cartridge filter is improved; and the double-cartridge filter is simple in structure and low in manufacturing cost.
Description
Technical field
This invention relates to a kind of filter, particularly a kind of duplex filter that can mutually switch in the fluid filter process.
Background technique
Fluid in the various kinds of equipment is mainly used in lubrication and cooling, but in use system element wearing and tearing can produce metallic dust and Sealing can be produced rubber impurities.These metallic dusts and rubber impurities are sneaked in the fluid, so that the reduction of the lubrication and cooling effect of fluid, so fluid needs constantly to filter in recycling process.But a lot of equipment need long-term continuous operation, therefore corresponding hydraulic system also needs thereupon long-term 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 to change or clean the filter core in the filter according to the situation of plugged filter.Common filter is to change by the filter core to filter in non-stop-machine situation at present.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of duplex filter that can in the not out-of-work situation of hydraulic system, safeguard filter.
Technological scheme: a kind of duplex filter, comprise the first filter, the second filter and the selector valve that is connected described first and second filter that connect by pipeline, described the first filter be connected filter and connect by upper and lower pipeline, be respectively equipped with filler opening and oil outlet in the middle of the upper and lower pipeline, described selector valve is comprised of oil-feed selector valve and fuel-displaced selector valve, described oil-feed selector valve and fuel-displaced selector valve are linkage structure in the same way, and described oil-feed selector valve and fuel-displaced selector valve are installed on respectively described filler opening and oil outlet place.Described duplex filter is connected in the hydraulic system, and fluid enters filter from filler opening, enters the first or second filter by the oil-feed selector valve, flows out this duplex filter by 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 illustrating 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 enters another filter and filters, and can not affect this moment in the situation of hydraulic work system the filter core of the filter of previous use is changed.
The bypass valve that also comprises the pipeline that connects respectively described filler opening and oil outlet both sides.The normal operation of avoiding affecting hydraulic system when reversing valve operated switch filtering device need to be distinguished the connecting bypass valve in the pipeline of filler opening and oil outlet both sides, open first bypass valve before the switching, closes bypass valve after switching is finished again.
Also comprise the 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, when force value reaches more renew cartridge of warning device setting value alarm device warning reminding user.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: 1, can change filter element not affecting in the situation of hydraulic system normal operation; 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 plan view of the present invention;
Fig. 3 is control principle drawing of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of duplex filter, comprise the first filter 1 that connects by pipeline, the second filter 2 be connected described first, tow filtrator 1,2 selector valve 3, described the first filter 1 and the second filter 2 are by upper, lower pipeline 4,5 connect, on, lower pipeline 4, be respectively equipped with filler opening 6 and oil outlet 7 in the middle of 5, described selector valve 3 is comprised of oil-feed selector valve 31 and fuel-displaced selector valve 32, described oil-feed selector valve 31 and fuel-displaced selector valve 32 are linkage structure in the same way, and described oil-feed selector valve 31 and fuel-displaced selector valve 32 are installed on respectively described filler opening 6 and oil outlet 7 places.Described duplex filter is connected in the hydraulic system, and fluid enters filter from filler opening 6, enters the first filter 1 or the second filter 2 by oil-feed selector valve 31, flows out this duplex filter by 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 illustrating 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 move the switching that realizes the first filter 1, the second filter 2 simultaneously, fluid enters another filter and filters, and can not affect this moment in the situation of hydraulic work system the filter core of the filter of previous use is changed.
The normal operation of avoiding affecting hydraulic system when reversing valve operated 3 switch filtering device need to be distinguished connecting bypass valve 8 in the pipeline of filler opening 6 and oil outlet 7 both sides, open first bypass valve 8 before the switching, closes bypass valve 8 after switching is finished again.
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, when force value reaches more renew cartridge of warning device 10 setting value alarm device warning reminding users.
