Abstract
The utility model discloses an integrated oil return filter which comprises a filter outer cover and a filter core. The integrated oil return filter is characterized in that a filter connector valve base is arranged at the top end of the filter outer cover; a connector communicated with the filter core is arranged on the valve base; and an oil outlet tube is arranged at the tail end of the filter outer cover. The utility model organically combines the connector valve base of an air controlled reversing valve for a hydraulic system and the filter outer cover into a whole to eliminate the joint of a composite tube, shortens the oil return path, reduces the oil leakage risk of a pipeline, and reduces the pressure loss of oil return; and the oil outlet tube is arranged at the tail end of the filter outer cove, so that the hydraulic oil after being filtered directly returns to an oil tank from the oil outlet tube, and no atomizing phenomenon occurs. Meanwhile, the raw materials are saved, the cost is reduced, and the installation and the maintenance are very convenient.
Description
Technical field
The utility model relates to filter, especially a kind of integral type return filter.
Background technology
Hydraulic system is simple in structure flexibly because of it, easy to operate, adjustable range is big, but stepless continuous is regulated, in all trades and professions, used widely, at every turn the hydraulic oil that pumps in the hydraulic oil container needs clean, free from admixture, do not have atomizing and just can make the hydraulic system energy fully, normally work, and need carrying out good filtration to the oil return in the hydraulic system, the hydraulic oil in the hydraulic fluid tank just can reach this standard, the structure of the return filter that uses is at present: the interface valve seat connects assembling to be used with four combined pipe fittings and combination of filters, this structure exists member many, the pipeline reducing, the oil return of filter mesh distributing, the oil return atomizating phenomenon is serious, hydraulic oil also leaks from hydraulic oil container oiling position, and installation and maintenance are very inconvenient.
Summary of the invention
The purpose of this utility model is to make that the hydraulic oil that pumps in the hydraulic oil container is clean, free from admixture, nothing atomizing, do not have and reveal, and has proposed a kind of integral type return filter.
For this reason, its technical scheme of the present utility model is: the integral type return filter, comprise filter outer cover, filter core, and it is characterized in that: be provided with the filter interface valve seat on the top of filter outer cover, valve seat is provided with the interface that is communicated with filter core.
Improvement to such scheme is: the tail end of described filter outer cover is provided with flowline.
Beneficial effect:
The utility model in use is combined into one the interface valve seat of hydraulic system Pneumatic reversal valve and the filter machine of being covered with, and has removed the compound tube joint, has shortened the oil return approach, has reduced the risk of pipeline leakage of oil, has reduced the return pressure loss; It is directly to get back in the fuel tank from flowline for the hydraulic oil after filtering that the tail end of filter outer cover is provided with flowline, can not produce atomizating phenomenon; Simultaneously also saved raw material, reduced cost, and installation and maintenance have been also very convenient.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
1 is filter outer cover, the 2nd among the figure, filter core, the 3rd, filter valve seat, the 4th, flowline, the 5th, filter taps seated connection mouth.
The specific embodiment
As shown in Figure 1: 1 is filter outer cover, the 2nd among Fig. 1, filter core, the 3rd, filter valve seat, the 4th, flowline, the 5th, filter taps seated connection mouth.In the use oil return pipe is directly connected to the interface 5 on the filter valve seat 3, makes hydraulic oil pass through interface 5 and filter to filter core 2, the hydraulic oil after the filtration confluxes after running into filter outer cover 1, gets back in the fuel tank by flowline 4 again.
Claims (2)
1, integral type return filter comprises filter outer cover, filter core, it is characterized in that: be provided with the filter interface valve seat on the top of filter outer cover, the interface valve seat is provided with the interface that is communicated with filter core.
2, integral type return filter according to claim 1, it is characterized in that: the tail end of described filter outer cover is provided with flowline.
