Abstract
The utility model relates to a base of a double-oil filter, comprising central joints, a machine cooler by-pass valve assembly, an oil filter base, a bowl-shaped stopper sheet, a steel ball, a safety valve spring, an O-shaped sealing ring, a lock nut and a main oil duct pressure-limiting valve nut, wherein the two central joints are respectively installed into two screw holes of the oil filter base at an angle of 90 degrees and screwed to the bottom; the machine cooler by-pass valve assembly is installed into the corresponding screw hole of the oil filter base and tightened; and the steel ball is placed into a bottom hole of the corresponding installed screw hole and then sequentially pressed to the safety valve spring, a main oil duct pressure-limiting valve seat, the O-shaped sealing ring and the lock nut and finally installed on the main oil duct pressure-limiting valve nut and tightly pressed. Because the double arrangement scheme is utilized, the filtering efficiency is greatly improved; and because the base comprises a main oil duct pressure-limiting valve and by-pass valve device, the safety of the oil filter and an engine is protected reliably.
Description
Technical field
The utility model belongs to field of internal combustion engine, relates to a kind of oil filter, relates in particular to a kind of duplex oil filter base.
Background technique
The effect of machine oil is the wearing and tearing that prevent the lubricated slit of engine interior movement parts, bearing play, and sealing, cooled engine parts, anticorrosive protection motor; The effect of oil filter is the foreign material in the filtering machine oil, and colloid, moisture are carried the machine oil of cleaning to each lubricating component.At present,, machine oil quality and filtering effect of requirement are also improved constantly,, then can have a strong impact on the normal operation of motor if the diesel-oil filter base can not satisfy the needs of motor along with the raising of engine boost pressure and reinforcing degree.Existing common oil filter base generally is an order oil filter, or other modes connect two oil filter, but ubiquity inefficiency, complex structure, shortcomings such as Security deficiency, in order to adapt to the demand of motor, be necessary to design a kind of simple, efficient, safe oil filter base to high lubricating oil effect.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, reliable operation, duplex oil filter base efficiently, and is smooth and easy with the lubrication system works that guarantees motor.
The technical solution of the utility model is: duplex oil filter base comprises center sub, main oil gallery pressure limiting valve seat, machine cooler by-pass valve assembly, oil filter base, plug screw, bowl type patch, steel ball, safety valve spring, O-ring seals, locking nut, main oil gallery pressure-limit valve nut.Two center subs are in 90 ° of two screws that are respectively installed to the oil filter base, and tighten at the end; Machine cooler by-pass valve assembly is installed in the oil filter base respective screw hole and tightens; Steel ball is put into the bottom outlet of the respective screw hole of installation, be pressed into safety valve spring, main oil gallery pressure limiting valve seat, O-ring seals, locking nut then successively, load onto main oil gallery pressure-limit valve nut at last and compress.
Plug screw is installed in the tapped hole of oil filter base correspondence; Bowl type patch is pressed in the hole of oil filter base.
The utility model can reach following beneficial effect:
The utility model is because what adopt is the duplex arrangement, and oil flow rate can increase and is twice, and filter efficiency increases greatly, and is also bigger to pressure, the temperature applicable surface of machine oil; Because the utility model contains main oil gallery pressure-limit valve and by-pass valve device; break down or accidental pressure when raising suddenly at motor; main oil gallery pressure-limit valve and bypass valve valve can in time be opened, and accident prevention is in possible trouble, thereby make the safety of oil filter and motor obtain reliable protection.
Description of drawings
Fig. 1 is the utility model duplex oil filter understructure schematic representation;
Fig. 2 is the utility model duplex oil filter understructure A-A sectional view;
Fig. 3 is the utility model duplex oil filter base machine oil schematic representation of flowing through.
Embodiment
The utility model will be further described with reference to the accompanying drawings below.As shown in Figure 1, duplex oil filter base comprises: center sub 1, oil filter base 2, machine cooler by-pass valve assembly 3, plug screw 4, bowl type patch 5, steel ball 6, safety valve spring 7, main oil gallery pressure limiting valve seat 8, O-ring seals 9, locking nut 10, main oil gallery pressure-limit valve nut 11.Two center subs 1 are in 90 ° of two M25～M28mm screws that are respectively installed to oil filter base 2, and tighten at the end; Plug screw 4 adopts NPT1/2, is installed in the NPT1/2 tapped hole of oil filter base 2 correspondences; Bowl type patch 5 is pressed in the corresponding hole of oil filter base 2; Machine cooler by-pass valve assembly 3 is installed in oil filter base 2 respective screw hole and tightens; Steel ball 6 is put into the bottom outlet of M18～M22mm tapped hole, be pressed into safety valve spring 7 then successively, main oil gallery pressure limiting valve seat 8, O-ring seals 9, locking nut 10 is loaded onto main oil gallery pressure-limit valve nut 11 at last and is compressed.
As shown in Figure 3: during work, the body main oil gallery comes oil to enter the filler opening of oil filter base 2, enters oil filter by filler opening, is flowed out by the filter block oil outlet after oil filter is filtered; If main oil gallery comes the overpressure of oil, then the main oil gallery pressure-limit valve can be opened pressure release automatically; If pressure still can not drop to safety range, the machine oil bypass valve can be opened pressure release so, thereby protection oil filter and motor itself run well.This novel patent simplicity of design, filter efficiency increases greatly, and is also bigger to pressure, the temperature applicable surface of machine oil; Because this practical main oil gallery pressure-limit valve and by-pass valve device of containing; break down or accidental pressure when raising suddenly at motor; main oil gallery pressure-limit valve and bypass valve valve can in time be opened, and accident prevention is in possible trouble, thereby make the safety of oil filter and motor obtain reliable protection.
