DETAILED DESCRIPTION
[0023] The utility model is further illustrated below in connection with the drawings and specific embodiments.
[0024] As Figure 1 , 2, 3, 4, 5, 6, this embodiment focuses on the integrated multi-channel oil supply valve in the actual operation of the double tank oil supply system, according to the state shown in different figures, the working process of the oil supply valve is described in detail.
[0025] An integrated multi-channel oil supply valve is constituted as follows:
[0026] Main body 1: made of brass material, with good corrosion resistance. The main body is provided with an open cavity 11 inside, and a group of oil supply ports 12 and a group of oil return ports 13 are arranged on the outer wall in the circumferential direction. Among them, the first oil supply port 121 and the second oil supply port 122 are coaxially arranged, and the third oil supply port 123 is perpendicular to the axis of the former two. Correspondingly, the first oil return port 131, the second oil return port 132 and the third oil return port 133 are arranged corresponding to the oil supply ports.
[0027] Valve core assembly 2: contains core 21, six hole diameter adapted through hole 22, O ring 23, spring 24, shaft 25, plug 26 and other components. The core is embedded in the cavity, and the through hole position on it corresponds to the oil supply port and the oil return port. The shaft is fixed in the annular boss 211 on the upper end of the core by the plug, and is equipped with O ring and spring to ensure smooth rotation and sealing performance.
[0028] Oil cover 3: installed on the upper end of the valve core assembly, used for sealing the cavity, and an annular gasket 31 is arranged between the main body and the valve core assembly to enhance the sealing effect.
[0029] Handle 4: connected with the shaft through screws, which is convenient for operators to rotate the core to adjust the through or closed state between the oil supply port and the oil return port.
[0030] In this embodiment, the interface connection relationship is: the first oil supply port 121 is connected with tank A (not shown in the figure), the second oil supply port 122 is connected with tank B (not shown in the figure), the first oil return port 131 is connected with tank A, the second oil return port 132 is connected with tank B, and the third oil supply port 123 and the third oil return port 133 are connected with the engine (not shown in the figure).
[0031] Full open state (Figure 3):
[0032] When the oil supply valve is in the full open state, rotating the handle 4 drives the core body 21 of the valve core assembly 2 to rotate to a specific position, so that the six through holes 22 on the core body 21 are respectively in precise communication with the first oil supply port 121, the second oil supply port 122, the third oil supply port 123, the first oil return port 131, the second oil return port 132 and the third oil return port 133. At this time, the oil in the oil tank A flows from the first oil supply port 121 into the open cavity 11 of the main body 1 under its own pressure or the action of the oil pump, and then smoothly flows to the third oil supply port 123 through the corresponding through hole 22 on the core body 21, thereby providing fuel for the engine; At the same time, the oil in the oil tank B also flows from the second oil supply port 122 into the cavity 11, and also flows to the third oil supply port 123 through the corresponding through hole 22 on the core body 21, realizing that the first oil supply port 121 and the second oil supply port 122 supply oil to the engine at the same time, meeting the large demand of the engine for fuel under high load operation and the like. When the engine works, the oil return flows from the third oil return port 133 into the cavity 11, and then flows to the first oil return port 131 and the second oil return port 132 through the corresponding through hole 22 on the core body 21, respectively, and finally returns to the corresponding oil tank A and oil tank B, completing the oil return process.
[0033] The third oil supply port 123 and the third oil return port 133 are closed, and the engine is turned off (Fig. 4):
[0034] Continue to rotate the handle 4 to drive the core body 21 to rotate to a specific angle, so that the through holes 22 on the core body 21 are completely disconnected from the third oil supply port 123 and the third oil return port 133. Since the third oil supply port 123 is the oil inlet channel of the engine, and the third oil return port 133 is the oil return channel of the engine, their closure causes the engine to be unable to obtain fuel supply, and at the same time, the oil return cannot be normally discharged, and the engine stops working. In this state, it is often used to prevent fuel leakage when the engine is stopped, or to isolate the engine from the oil tank during system maintenance.
[0035] The first oil supply port 121 and the first oil return port 131 are closed, the oil tank B is single-supplied, and the engine is single-oiled to the oil tank B (Fig. 5):
[0036] Again, operate the handle 4, drive the core 21 to rotate, let the part through hole 22 on the core 21 keep in communication with the second oil supply port 122, the third oil supply port 123, the second oil return port 132, the third oil return port 133, and be disconnected with the first oil supply port 121, the first oil return port 131. At this time, the oil tank B becomes the only oil supply source, and the oil in the oil tank B flows into the cavity 11 from the second oil supply port 122, flows to the third oil supply port 123 through the corresponding through hole 22 on the core 21, and provides fuel for the engine. The oil return generated by the engine flows into the cavity 11 from the third oil return port 133, flows to the second oil return port 132 through the corresponding through hole 22 on the core 21, and finally returns to the oil tank B, realizing single oil supply of the oil tank B and single oil return of the engine to the oil tank B. This state is suitable for the case that the oil tank A fails or only the oil tank B needs to be used for oil supply according to the actual work arrangement.
[0037] The first oil supply port 121, the third oil supply port 123, the first oil return port 131, and the third oil return port 133 are opened, and the second oil supply port and the second oil return port are closed (Fig. 6):
[0038] By operating the handle 4, drive the core 21 to rotate, let the part through hole 22 on the core 21 keep in communication with the first oil supply port 121, the third oil supply port 123, the first oil return port 131, the third oil return port 133, and be disconnected with the second oil supply port 122, the second oil return port 132. At this time, only the oil tank A participates in oil supply, and the oil in the oil tank A flows into the cavity 11 from the first oil supply port 121, and then flows to the third oil supply port 123 through the corresponding through hole 22 on the core 21, to supply fuel for the engine. The oil return generated by the engine working flows into the cavity 11 from the third oil return port 133, flows to the first oil return port 131 through the corresponding through hole 22 on the core 21, and finally returns to the oil tank A, realizing single oil return of the engine to the oil tank A. This state is suitable for the case that the oil in the oil tank B is insufficient, or only the oil tank A needs to be used for oil supply to meet the engine working demand under the current working condition.
[0039] The above embodiment shows in detail the different working states and switching processes of the integrated multi-way oil supply valve in the double-oil-tank oil supply system, fully embodies the advantage that the oil supply valve can realize flexible control of the oil way through simple operation, and can effectively meet the use demand of the double-oil-tank oil supply system under various complex working conditions
[0040] The above embodiment is exemplary, and the purpose is to illustrate the technical concept and characteristics of the utility model, so that the personnel familiar with this field can understand the content of the utility model and implement it accordingly, and the protection scope of the utility model cannot be limited thereby. Any equivalent change or modification according to the spirit and essence of the utility model should be covered within the protection scope of the utility model.
