Description
Technical field:
The utility model relates to automotive fields, and in particular to a kind of block-resistant type diesel fuel filter central tube.
Background technique:
The effect of diesel fuel filter is the objectionable impurities and moisture filtered out in fuel system, protects the normal work of engine
Make, reduce abrasion, avoid blocking, improve engine life, the filtering of diesel fuel filter mostly uses filter paper, also have using felt or
High molecular material.The filtering of gasoline filter mostly uses filter paper, also has using nylon cloth, high molecular material, diesel oil filtering
The structure of device is substantially identical as oil filter, there is interchangeable and rotation fitting type, and the central tube of existing diesel fuel filter is adopted mostly
Tubular structure is coiled into sheet metal coil to be made, it is not high to the support strength of filter paper, it is easily damaged, the oil-through-hole of existing central tube
Diameter is too small, will lead to blocking, reduces to the filter efficiency for wiping diesel oil, influences to work normally, and cannot make full use of filter paper,
Cause the excessively high serious carbonization of local use rate to cause to waste, and will cause blocking, the utility model provides a kind of high-intensitive diesel oil
Filter central pipe.
Utility model content:
The technical problem to be solved by the utility model is to provide a kind of block-resistant type diesel fuel filter central tubes.
The following technical solution is employed for technical problem to be solved in the utility model to realize: a kind of block-resistant type diesel fuel filter
Clear device central tube, including support tube, the side wall of the support tube offer several rectangular through-holes, every layer of rectangular through-hole setting
There are six groups, the bottom of the support tube is fixedly connected with chassis, and the bottom on the chassis offers fuel feed hole, the top on the chassis
Portion is fixedly connected with diversion pipe, the bottom of the diversion pipe and fuel feed hole face and mutual connection, and the diversion pipe is located at support
The inside of pipe.
Preferably, the chassis, which is run through, offers air vent.
Preferably, the length of the diversion pipe is less than the length of support tube.
Preferably, the material of the chassis, diversion pipe and support tube is plastic material.
Preferably, the thickness of the support tube is set as 1.5mm-3.5mm.
The beneficial effects of the utility model are: the utility model structure is simple, convenient and practical, central tube plastics
The thickness of material, 1.5mm-3.5mm ensure that strength and stiffness, solve problem of rustiness compared to metal material, improve use
Service life, and support strength is enhanced, the rectangular through-hole opened up substantially increases the logical oil of diesel oil while guaranteeing rigidity
Property, it prevents from blocking, enhances the efficiency of filtering, the design of chassis and petroleum pipeline can be such that filter paper sufficiently uses, and avoid local carbon
Change causes to waste, and prolongs the service life, application easy to spread.
