Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of aero-engine lubrication transmission system, and relates to a fuel oil heat exchanger structure, in particular to a highly integrated fuel oil heat exchanger with a three-way valve and a fuel oil filter. BACKGROUND

[0002] The fuel oil heat exchanger is a key component of the aero-engine lubrication transmission system, and uses fuel oil as a cold source to cool high-temperature lubricating oil in the aero-engine lubrication transmission system, so as to control the temperature of the lubricating oil within a certain range. The heated fuel oil is then burned in the engine or returned to the fuel tank.

[0003] The applicant applied for a Chinese invention patent entitled "Fuel Oil Heat Exchanger with Double Valve Structure" (publication number CN111535927A, publication date August 14, 2020) in 2020. The patent discloses a design scheme with a double valve structure. However, the scheme has some problems in subsequent practice. For example, the position of the fuel oil heat exchanger is generally lower than that of the lubricating oil tank. At this time, due to the siphon effect, lubricating oil may leak out of the engine from the high-altitude valve in a static state. For the steel ball type anti-siphon valve structure, due to manufacturing problems, there may be a gap between the steel ball and the valve seat, and the fit is poor. Leakage may occur when the engine is stationary, causing the anti-siphon device to fail. For example, for an aero-engine, especially a military engine, it generally needs to be overhauled after 300-1000 hours of use. The maintenance time of the lubricating oil filter is even shorter, and it generally needs to be disassembled, cleaned, or even replaced every 50 hours. The traditional structure cannot achieve the separate disassembly and replacement of the lubricating oil filter, resulting in high cost. At the same time, the traditional single-layer structure of the lubricating oil filter has a small pollution capacity, and the maintenance period is short. In addition, when the lubricating oil filter is disassembled, the residual fluid in the system is also prone to leakage, which may contaminate other accessories of the engine, making the maintenance work more difficult. SUMMARY

[0004] To solve the above problems, the utility model aims to provide a fuel oil heat exchanger with a highly integrated lubricating oil filter and three-way valve. The anti-siphon valve has good stability, solves the leakage problem of the anti-siphon device, improves the replacement process of the lubricating oil filter, reduces maintenance costs, reduces the amount of lubricating oil leakage during replacement, increases the pollution capacity of the lubricating oil by more than ten times, prolongs the service life of the lubricating oil filter, and reduces the work intensity of maintenance personnel.

[0038] The lubricating oil filter assembly 1801 adopts a folded wave type filter screen structure, is composed of an end cover, an inner shell and a filter screen, the filter screen material adopts 316L0.05 / 0.036 material, and the inner shell is processed from 1Cr18Ni9Ti rod material.

[0045] As shown in Figure 1 , Figure 2 , Figure 3 When the fuel lubricating oil heat exchanger is blocked by foreign matters, lubricating oil enters the lubricating oil control assembly b from the lubricating oil inlet 11, opens the normally closed lubricating oil bypass valve assembly 12, and directly flows into the next component (the maintenance valve assembly 17).

[0046] The oil filter double valve assembly 18 is provided at the outlet end of the oil control assembly b, and the outer adjusting seat 1813 and the oil plug 1814 can adjust the elastic force of the anti-siphon valve spring 1809 to set the opening pressure of the anti-siphon valve 1807. When the oil pressure is below the set pressure, the anti-siphon valve 1807 is in a closed state. When the oil pressure reaches the set value, the anti-siphon valve 1807 is opened, and the oil flows normally.

When the oil filter (i.e., the filter element in the oil filter assembly 1801) is blocked, the pressure of the oil will be greater than the set working pressure of the oil filter safety valve 1805. At this time, the oil will open the oil filter safety valve 1805 and flow into the next component (the oil outlet 16).

[0049] As shown in Figure 4 The maintenance valve assembly 17 is integrated in the connection section between the oil control assembly b and the oil outlet end of the fuel-oil heat exchanger a. The maintenance valve 1702 is in contact with the end cover of the oil filter assembly 1801, and the elastic force of the maintenance valve spring 1701 is adjusted to open the oil outlet end of the fuel-oil heat exchanger a in a normal state. When the oil filter double valve assembly 18 is disassembled for maintenance, the maintenance valve 1702 is pushed to the oil outlet end of the fuel-oil heat exchanger a by the elastic force of the maintenance valve spring 1701 to seal and limit the flow of the outlet oil (blocked by the outer cylindrical surface of the maintenance valve 1702), and at the same time, it is limited by the oil filter elastic baffle 1802, thereby reducing the leakage during assembly and disassembly.
