Abstract
The utility model relates to a base structure of an integrated type fuel oil prefilter, which is characterized by comprising a base body, a valve seat and a one-way diaphragm valve, wherein the base body comprises an installation flange face, a main oil duct and an oil pumping passage, the main oil duct and the oil pumping passage are arranged in the base body and are respectively arranged at the left side and the right side of the base body, and the one-way diaphragm valve and the valve seat are installed at the oil inlet end and the oil outlet end of the oil pumping passage fixed in the base body. In the utility model, the entire base structure is compact, safe, reliable, practical and convenient and has complete functions.
Description
Technical field
The utility model belongs to the technical field of motor car engine fuel filter, particularly a kind of integrated fuel prefilter understructure.
Background technique
In recent years because the increasingly stringent of vehicular engine emission regulation demands will inevitably cause the further improvement and the raising of fuel filter.The clean and efficient performance to motor of oil supply system plays crucial effects.So,, must improve the function of fuel filter more for guaranteeing the efficient work reliably of oil supply system.The function of fuel oil prefilter is exactly before fuel oil enters oil transfer pump and oil sprayer the impurity in the fuel oil, water and other pollutant to be filtered out, and guarantees to have the vitals such as the oil transfer pump of precision pair and oil sprayer can proper functioning.
Owing to influenced by oil product, have the fuel oil prefilter now in use for some time, oil pumping chamber body inside will cover one deck greasy filth shape impurity, causes the situation of fuel oil prefilter hand oil pump pump shortage of oil even inefficacy, is difficult to guarantee the proper functioning of oil supply system.
Summary of the invention
The utility model purpose provides a kind of integrated fuel prefilter understructure.
The technical solution of the utility model is achieved in that
A kind of integrated fuel prefilter understructure, it is characterized by: it is made up of a base body, valve seat and one-way membrane plate valve, the base body is made up of mounting flange face, main oil gallery and pump oil passage, have main oil gallery and pump oil passage in the base body, main oil gallery and pump oil passage are arranged in the left side and the right side of base body, and one-way membrane plate valve and valve seat are fixed on the oil inlet end and the oil outlet end of pump oil passage in the base body.
The utlity model has whole understructure compactness, function is complete, and is safe and reliable, practical and convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
A kind of integrated fuel prefilter understructure, it is characterized by: it is made up of a base body 1, valve seat 2 and one-way membrane plate valve 3, base body 1 is made up of mounting flange face 4, main oil gallery 5 and pump oil passage 6, have main oil gallery 5 and pump oil passage 6 in the base body 1, main oil gallery 5 and pump oil passage 6 are arranged in the left side and the right side of base body 1, one-way membrane plate valve 3-1 and valve seat 2-1 are fixed on the oil inlet end of pump oil passage in the base body, and one-way membrane plate valve 3-2 and valve seat 2-2 are fixed on the oil outlet end of pump oil passage in the base body.
Embodiment:
Shown in Figure 1, before motor does not start, need pump when oil, fuel oil under the suction function that hand oil pump produced the unlatching by being arranged in a pair of one-way membrane plate valve 3-1 in the straight-through structure and 3-2 with fuel oil by pump oil passage 6 pumps to filter core; During the motor proper functioning, fuel oil arrives filter core simultaneously by main oil gallery 5 and pump oil passage 6 under the suction function that oil transfer pump produced.Like this, just fundamentally solve the problem of hand oil pump pump shortage of oil even inefficacy, guaranteed the proper functioning of oil supply system to the full extent.
