Description
Technical field
The utility model relates to a kind of gasoline filter, specifically refers to a kind of gasoline filter with unidirectional flowline.
Background technology
The structure of traditional gasoline filter generally comprises the shell being provided with inner chamber, to be arranged on shell and with the oil inlet pipe of shell inner cavity conducting, flowline, element kit is provided with in the inner chamber of shell, element kit includes refill, refill upper cover, refill base, refill is fastened between refill upper cover and refill base, refill and refill upper cover, all sealing is formed between refill base, oil duct is provided with in refill, flowline and oil duct conducting, on filter element upper cover, corresponding oil duct position is provided with through hole, gasoline enters inner chamber from oil inlet pipe, successively through oil duct after paper element filtering, through hole, flowline flows out.
But the gasoline filter of this structure, because element kit can not be located well, thus makes element kit easily produce in chamber in the enclosure and rocks, thus cause the filter effect of gasoline filter bad.
In addition, this traditional gasoline filter in use, once flowline side pressure anomaly and be greater than oil inlet pipe lateral pressure, hydraulic oil can enter into shell inner cavity from flowline, and makes the filter paper of element kit be broken through by hydraulic oil and scrap.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of good filtration effect and can prevent hydraulic oil from flowing backwards, and improves the gasoline filter with unidirectional flowline of cleaner stability in use.
For achieving the above object, the technical solution of the utility model includes the shell being provided with inner chamber, be arranged at the oil inlet pipe communicated on shell and with shell inner cavity, flowline, element kit is provided with in the inner chamber of shell, element kit includes refill, refill upper cover, refill base, described refill is fastened between refill upper cover and refill base, shell inner cavity is separated into refill inner chamber and refill exocoel by refill, described refill inner chamber communicates with oil inlet pipe, refill exocoel is connected with flowline, the diapire of described inner chamber is provided with three and around refill datum axle to brace rod of the equally distributed end, described refill base supports with end brace rod and coordinates, the sidewall of described inner chamber is provided with three oblique convex tendons of longitudinal direction that downward thickness increases gradually, this oblique convex tendon bottom of three longitudinal directions connects with the outer end of three foundation brace rods respectively, the lateral edges of described refill base coordinates with the oblique convex tendon positioning supports of this longitudinal direction, the check valve along fuel-displaced direction one-way conduction is provided with in described flowline.
By this setting, the combination of end brace rod and longitudinal bracing muscle, steadily is fixed in shell in location, ground by element kit, prevents described element kit from rocking in inner chamber, ensure good filter effect further.In addition, this setting, arranges check valve in flowline, can prevent the hydraulic oil outside flowline from refluxing and damaging refill, improve stability and the service life of use of the present utility model.
Further setting is that described check valve includes nonreturn valve core and nonreturn valve core back-moving spring, the inwall of described flowline is provided with annular one-way valve seat, described nonreturn valve core slippage is arranged in flowline, and the upper end of this nonreturn valve core and annular one-way valve seat seal adaptation, the sidewall of described nonreturn valve core is provided with oil guiding hole, described flowline the lower end of nonreturn valve core is provided with spring base, the two ends up and down of described nonreturn valve core back-moving spring abut with nonreturn valve core and spring base effect respectively and coordinate.This setting provides a kind of practicality and one-way valve structures easy for installation.
In sum, the utility model has the advantages that good filtration effect and can prevent hydraulic oil from flowing backwards, improving cleaner stability in use.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
