Abstract
The invention belongs to the field of filters, and in particular relates to a double-drum paper filter core filter. The double-drum paper filter core filter comprises two filter drums and a change-over valve between the two filter drums, and is characterized in that: the change-over valve is provided with an oil adjusting valve; and an oil adjusting passage is formed on the change-over valve corresponding to the oil adjusting valve. By arranging the oil adjusting valve on the change-over valve of the filter, oil can be gently replenished into the filter drum of a single filter core after the filter core is cleaned, so the conditions of oil reflow and negative pressure formation are avoided during normal work, the filter causes less interference on a system during the conveying of a filter medium, and the impact of the reflowed oil on a paper filter core is avoided to prevent deformation or cracking of the paper filter core; and a groove is formed on the back part of the change-over valve and the oil flows into the groove on the back part of the change-over valve through the oil adjusting valve to balance stressing of the change-over valve during work, so that the friction of the change-over valve is relieved, the change-over valve rotates more lightly and smoothly and the service life of the change-over valve is prolonged.
Description
Technical field
The present invention relates to a kind of bitubular papery filter core filter, belong to the filter field.
Background technique
Existing bitubular papery filter core filter (for example model is the lubricating oil filter of SZL65) is for the lubricant oil of purifier vessel with engine lubrication system designs, and filter is after work a period of time, and the impurity of cartridge surface can get more and more; Filter resistance can be increasing; When Resistance Value surpasses specified resistance, just must rotate changing valve, a problem filter cylinder is quit work; And the replacing papery filter core that opens it, clean safe filter cylinder simultaneously.After ressembling, rotate changing valve, change the work filter cylinder, use with quadrat method and clean another filter cylinder.But in the process of rotating changing valve change work filter cylinder, owing to being empty in the filter cylinder, pressure wherein is ambient pressure; Can cause fluid moment refluence like this; Make motor oil oil supply system moment negative pressure, although this process can be very short, concerning the high motor of oil supply system stability requirement; Be easy to impairedly, be unfavorable for the long-term use of equipment.
Summary of the invention
According to above deficiency of the prior art; The technical problem that the present invention will solve is: the bitubular papery filter core filter that a kind of convenience for washing, long working life are provided; Make the handoff procedure of two filter cylinder working staties of filter more steady; Can not produce because the pressure surge that oil circuit conversion is caused and, and make the changing valve running light the impact of filter core.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bitubular papery filter core filter; Comprise two filter cylinders and be arranged on the changing valve between two filter cylinders; It is characterized in that: on the described changing valve oil adjusting valve is set, corresponding oil adjusting valve is provided with on changing valve transfers oily passage.
Through on the changing valve of filter, setting up oil adjusting valve; Make clean can fluid is mild behind the single filter core the filter cylinder that replenishes its place; Thereby the fluid when having avoided proper functioning refluxes, forms the situation of negative pressure, makes filter in the course of conveying of filter medium, cause interference still less to system, the impact of having avoided backflow fluid that the papery filter core is caused; Thereby prevent papery filter core distortion or break, prolonged the operating life of filter core.
Described changing valve back is provided with groove.Fluid flows in the groove at changing valve back through oil adjusting valve, makes changing valve stress balance at work, thereby has alleviated the friction of changing valve self, makes changing valve rotate more brisk smoothness, has prolonged the working life of changing valve.
Working principle and process:
Lubricating oil gets into from the filter import, arrives the filter oil suction chamber through changing valve, the papery filter element filtering in filter cylinder, and pass through filter cylinder to the cleaning oil pocket, again by being exported to lubricating system of diesel oil engine.Generally, answer two filter cylinders to use simultaneously, to prolong the working life of filter core.When more changing jobs filter cylinder, earlier with the oil adjusting valve underspin, will transfer oily passage to block, when treating that filter cylinder cleans up,, make filter cylinder be full of oil again with revolving on the oil adjusting valve, will lead to the fuel tap underspin again, rotate changing valve, use with quadrat method and clean the opposite side filter cylinder.
The beneficial effect that the present invention had is: a kind of bitubular papery filter core filter is provided; Through on the changing valve of filter, setting up oil adjusting valve; Make clean can fluid is mild behind the single filter core the filter cylinder that replenishes its place; Thereby the fluid when having avoided proper functioning refluxes, forms the situation of negative pressure, makes filter in the course of conveying of filter medium, cause interference still less to system, the impact of having avoided backflow fluid that the papery filter core is caused; Thereby prevent papery filter core distortion or break, prolonged the operating life of filter core; The changing valve back is provided with groove, and fluid flows in the groove at changing valve back through oil adjusting valve, makes changing valve stress balance at work, thereby has alleviated the friction of changing valve self, makes changing valve rotate more brisk smoothness, has prolonged the working life of changing valve.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done and to be further described:
Shown in Fig. 1～3, bitubular papery filter core filter comprises two filter cylinders 1 and is arranged on the changing valve 2 between two filter cylinders 1, and oil adjusting valve 3 is set on the changing valve 2, and corresponding oil adjusting valve 3 is provided with on changing valve 2 transfers oily passage 4.
Through on the changing valve 2 of filter, setting up oil adjusting valve 3; Make clean can fluid is mild behind the single filter core the filter cylinder that replenishes its place; Thereby the fluid when having avoided proper functioning refluxes, forms the situation of negative pressure, makes filter in the course of conveying of filter medium, cause interference still less to system, the impact of having avoided backflow fluid that the papery filter core is caused; Thereby prevent papery filter core distortion or break, prolonged the operating life of filter core.
Described changing valve 2 backs are provided with groove 5.Fluid flows in the groove 5 at changing valves 2 backs through oil adjusting valve 3, makes changing valve 2 stress balance at work, thereby has alleviated the friction of changing valve 2 self, makes the changing valve 2 rotate more brisk smoothness, has prolonged the working life of changing valve 2.
Working principle and process:
Lubricating oil gets into from the filter import, arrives the filter oil suction chamber through changing valve 2, the papery filter element filtering in filter cylinder 1, and pass through filter cylinder 1 to the cleaning oil pocket, again by being exported to lubricating system of diesel oil engine.Generally, answer two filter cylinders 1 to use simultaneously, to prolong the working life of filter core.When more changing jobs filter cylinder, earlier with oil adjusting valve 3 underspins, will transfer oily passage 4 to block, when treating that filter cylinder cleans up, with revolving on the oil adjusting valve 3, make filter cylinder be full of oil again, will lead to fuel tap 3 underspins again, rotate changing valve 2, use with quadrat method and clean the opposite side filter cylinder.
