Abstract
The utility model discloses a double-cartridge filter switching valve which comprises two filter cartridges and two triple valves connecting with the two filter cartridges through connecting pipes, and oil inlets are arranged on the triple valves. The utility model is characterized in that the double-cartridge filter switching valve also comprises a double-single-way valve connecting with the two filter cartridges through connecting pipes, and an oil outlet is arranged at the middle position of the double-single-way valve.
Description
Technical field
The utility model relates to a kind of transfer valve with double-drum filter.
Background technology
The double-drum filter transfer valve is widely used on the various oil-servicing facilities, and two cartridge filter alternations are so that clean another; Existing double-drum filter transfer valve, as shown in Figure 1, comprise two cartridge filters 11, pass through the upper and lower triple valve 7 that supporting separately tube connector is connected with two cartridge filters 11 respectively, oil-in 8 and oil-out 9 are located at respectively on two triple valves 7, and the rotating shaft of two triple valves 7 links to each other by connecting rod 10; When two triple valves 7 are commutated simultaneously, a cartridge filter is closed, another cartridge filter is opened, realize the switching of two cartridge filters 11, but during two triple valves 7 commutations, owing to cooperate rotating shaft tight, two triple valves 7 to link to each other, the power that needs is big, operating difficulties, and the oil-in 8 and the oil-out 9 of two triple valves 7 can not rotate around axis, are unfavorable for being connected of oil-in 8 and oil-out 9 and pipeline, use inconvenient; And the required precision height of duplex triple valve makes trouble, sealing surface the grinding difficulty, and be not easy to guarantee sealing, leak easily.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of double-drum filter transfer valve is provided, and it is easy to operate, easy to use, manufacturing is simple, advantage of good sealing effect.
For achieving the above object, double-drum filter transfer valve of the present utility model, the triple valve that comprises two cartridge filters, is connected with two cartridge filters by tube connector, oil-in is located on the triple valve, it is characterized in that also comprising the double check valve that is connected with two cartridge filters by tube connector, oil-out is arranged at the meta of double check valve;
During commutation, only need the crossover tee valve, at this moment the spool of double check valve can automatically switch by oil pressure, and therefore the power of commutation is less, easy to operate; The oil-out of double check valve can be done 360 ° of rotations around axis, is convenient to be connected with pipeline, and is easy to use; And double check valve is easy to manufacture, good sealing effect.
Description of drawings
Fig. 1 is the structural representation of existing double-drum filter transfer valve.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
By shown in Figure 2, this double-drum filter transfer valve, the triple valve 2 that comprises two cartridge filters 1 and 6, is connected with two cartridge filters 1 by tube connector, by the double check valve 3 that tube connector is connected with two cartridge filters 1, oil-in 4 is located on the triple valve 2, oil-out 5 is arranged at the meta of double check valve 3;
During use, triple valve 2 turns to cartridge filter 1, and hydraulic oil enters in the cartridge filter 1 from oil-in 4, and flows into double check valve 3 from the outlet of its lower end, the spool of double check valve 3 pins the outlet of cartridge filter 6 lower ends automatically by oil pressure, and hydraulic oil flows out from the oil-out 5 of double check valve 3 metas; When needing commutation, only need crossover tee valve 2, hydraulic oil enters in the cartridge filter 6 from oil-in 4, and at this moment the spool of double check valve 3 automaticallyes switch by oil pressure, pins the outlet of cartridge filter 1 lower end, and hydraulic oil flows out from the oil-out 5 of double check valve 3 metas; Because only need operation triple valve 2, therefore the power of commutation is less, easy to operate; The oil-out 5 of double check valve 3 can be done 360 ° of rotations around axis, is convenient to be connected with pipeline, and is easy to use; And double check valve 3 is easy to manufacture, good sealing effect.
