Detailed Description
For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.
Example 1:
as shown in fig. 1, a two-way valve structure for a lubrication station includes a hollow valve body 2, one end of the valve body 2 is communicated with an outlet of a radiator, the other end is communicated with an oil tank, an axial groove 21 is formed in the valve body 2 near the radiator, a hollow valve core seat 5 is installed in the axial groove 21, a valve core 4 is installed at one end of the valve core seat 5 far away from the radiator, the valve core 4 can slide axially along the outer surface of the valve core seat 5, the outer diameter of the valve core 4 is smaller than the diameter of the axial groove 21 and larger than the inner diameter of the valve body 2, a hollow installation seat 1 is installed at one end of the valve body 2 near the radiator, and an elastic element in contact with the valve core.
Preferably, the elastic element is a spring 3.
The working principle is as follows: when the lubrication station stops working, the spring 3 is in a natural state and is in contact with the valve core 4, and the valve core 4 is not in contact with the end face of the axial groove 21. When the lubricating station runs, lubricating oil in the radiator can pass through the valve core seat 5 and give the valve core 4 a pressure far away from the direction of the radiator, the pressure can push the valve core 4 to slide towards the direction far away from the radiator until the end face of the valve core 4 is tightly abutted against the end face of the axial groove 21, at the moment, the valve core 4 blocks the interior of the valve body 2, and meanwhile, the spring 3 is compressed.
When the lubrication station stops operating, the pressure applied to the valve core 4 by the lubricating oil is reduced, the valve core 4 slides on the valve core seat 5 towards the direction of the radiator under the action of the elastic force of the spring 3 until the spring 3 recovers to the original position, at the moment, the valve core 4 is not contacted with the end face of the axial groove 21, and the valve core 4 does not seal the inside of the valve body 2, so the lubricating oil in the radiator can sequentially pass through the valve core seat 5, the gap between the valve core seat 5 and the valve core 4 and the gap between the valve core 4 and the axial groove 21 and finally flow into the oil tank through the valve core 4.
Through the technical scheme, when the lubricating station does not operate, the lubricating oil in the radiator can flow back to the oil tank, so that the inside of the radiator is in a cavity state as much as possible, and the condition that the radiator is burst and damaged due to expansion caused by heat and contraction caused by cold in a cold area is reduced, thereby reducing the maintenance time of the radiator and reducing the corresponding maintenance cost.
Example 2:
as shown in fig. 1 to 2, this embodiment gives a more specific form of the structure on the basis of the above-described embodiment. That is, the valve core seat 5 includes a valve cylinder 51 and a connecting seat 52 which are integrally formed with each other from left to right, the connecting seat 52 is installed in the axial groove 21, and the valve core 4 is provided on the valve cylinder 51 and can slide along the axial direction of the valve cylinder 51. When the lubrication station is normally operated, the valve element 4 moves in a direction away from the radiator along the outer surface of the valve cylinder 51 when receiving the pressure of the lubricating oil; when the lubrication station stops operating, the valve element 4 moves in a direction approaching the radiator along the outer surface of the valve cylinder 51 by the elastic force of the spring 3.
Preferably, the end face of the connecting seat 52 and the end face of the valve body 2 are located on the same vertical plane, and the end face of the mounting seat 1 and the other end face of the valve body 2 are located on the same vertical plane, so that the mounting seat 1 and the connecting seat 52 are both mounted in the valve body 2, and the structure is more attractive.
The rest is the same as example 1, and therefore, will not be described herein.
The embodiment of the present invention is the above. The specific parameters in the above embodiments and examples are only for the purpose of clearly showing the verification process of the present invention, and are not used to limit the protection scope of the present invention, which is still subject to the claims, and all the equivalent structural changes made by using the contents of the specification and drawings of the present invention should be included in the protection scope of the present invention.
