Detailed Description
As shown in fig. 1 to 3, a hydraulic lubrication valve specifically disclosed in this embodiment includes a valve body 13, a valve rod 11 is disposed in the valve body 13, a second end cap 14 is disposed at one end of the valve body 13, the second end cap 14 is connected to the valve body 13 through a second screw 16, a valve core 10 is disposed inside the valve body 13, the valve core 10 is located above the valve rod 11, the valve core 10 is connected to the valve body 13 through a plug screw 7, the plug screw 7 is sleeved with a first spring 9, one end of the first spring 9 is fixedly connected to the valve core 10, the other end of the first spring 9 is fixedly connected to the plug screw 7, one end of the valve body 13 is disposed with a first end cap 3, the first end cap 3 is connected to the valve body 13 through a first screw 1, a pressure measuring joint 5 is fixedly connected to the valve body 13, an O-shaped ring 6 is disposed between the pressure measuring joint 5 and the valve body 13, a second spring 17 is disposed in the second end cap 14, and the second spring 17 is fixedly connected to the inside the valve body 13 and to an inner wall of the valve body 13 in unit. The valve core has the advantages of reasonable structural design, convenience in use, sensitive response and simple structure, and adopts a structure that one end of the valve core is provided with the small throttling hole, pressure oil is introduced to push the valve core to change the position, and the spring is reset. When the device is used, oil is fed through the oil inlet P, the working pressure is 0.45-0.5MPa, and the oil inlet P is communicated with the oil return port T1 and the oil return port T2; the working pressure of the overflow valve is 0.3-0.35MPa, when the pressure of the oil inlet P is increased to exceed 0.5MPa, the overflow valve starts to overflow, pressure oil is introduced in the using process to push the valve core 10 to change the position, and the valve core 10 can be pushed to reset under the action of the first spring 9.
Specifically, the washers 2 are disposed between the second screw 16 and the second end cap 14, and between the first screw 1 and the first end cap 3. When the device is used, the gasket 2 can be used to protect the surface of the second end cap 14 from scratching by the screw 16, dispersing the pressure of the screw 16 against the second end cap 14.
Specifically, a gasket 15 is disposed between the end cap 14 and the valve body 13. When this device is used, the gasket 15 can improve the sealing performance in the valve body 13, and the leakage of the hydraulic oil can be prevented.
Further, a combined gasket 8 is arranged between the plug screw 7 and the valve body 13.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but these descriptions should not be construed as limiting the scope of the present invention, and the technical contents not described in detail in the present invention are known in the art.
