Example 1

As shown in the figure, the utility model provides a one-way valve structure with a handle, which comprises a flange plate 1, wherein the flange plate 1 is used for connecting the one-way valve with an oil storage tank. First through holes 11 are uniformly distributed in the flange plate 1, and the first through holes 11 can provide positions for bolts, so that the bolts can fix the flange plate 1 on an oil storage tank. Four lifting lugs 12 are arranged on the flange plate 1, and the four lifting lugs 12 are symmetrically distributed and can be used for moving the flange plate 1.

The flange plate 1 is connected with an outer chuck 2, an inner thread is arranged on the outer chuck 2, a valve wall 3 is arranged on the inner side of the outer chuck 2, an outer thread is arranged on the valve wall 3, and the outer chuck can be matched with the valve wall 3 to be in threaded connection for fixing the valve wall 3.

A handle 4 is arranged above the valve wall 3, and the handle 4 is an expandable handle. One end of each of the two handles 4 is fixed at the top of the valve wall 3 through a connecting shaft, and the handles 4 can rotate around the connecting shaft, so that the handles 4 can be conveniently unfolded and contracted. The handle 4 is convenient to detach and install the valve wall 3 when being unfolded, and the check valve is convenient to clean. Not only can save space when contracting, can also seal the cavity, avoid the cavity direct to contact with the external world, thereby when using in open-air adverse circumstances, can prevent that the pollutant from getting into first cavity 51 and causing the pollution, reduce the wearing and tearing between spring case 6 and the cavity simultaneously, the life of extension check valve.

The valve wall 3 is internally provided with a cavity which provides space for the movement of the spring valve core 6 and the oil flow. The cavity includes first cavity 51, and first cavity 51 below is equipped with second cavity 52, and second cavity 52 below is equipped with third cavity 53, and third cavity 53 below is equipped with fourth cavity 54. The second cavity 52 has a larger diameter than the first cavity 51, the first cavity 51 has the same diameter as the third cavity 53, and the second cavity 52 has the same diameter as the fourth cavity 54.

A spring valve core 6 is arranged in the cavity, and the spring valve core 6 can control whether oil flows out of the one-way valve. The spring valve core 6 comprises a valve core top sleeve, a second through hole is arranged on the side wall of the valve core top sleeve, and oil can flow into a second cavity 52 of the one-way valve from the oil storage tank through the second through hole. The top of case top cover is equipped with the chamfer, closely laminates with the junction of first cavity 51 and second cavity 52, can prevent the fluid in the second cavity 52 from flowing out. The height of the valve core top sleeve is larger than that of the second cavity 52, the bottom of the valve core top sleeve is positioned in the third cavity 53, and the third cavity 53 plays a guiding role on the valve core top sleeve.

The valve core top sleeve is internally provided with a spring, the upper end of the spring is contacted with the upper end of the valve core top sleeve, and the lower end of the spring is connected with the valve core base. When the oil outlet rod pushes the valve core top sleeve, the valve core top sleeve downwards compresses the spring, the spring pushes the valve core base to downwards move, and oil in the second cavity 52 flows out of the one-way valve.

The spool base is attached to the fourth cavity 54, and the fourth cavity 54 provides guidance for the spool base. The valve core base is hollow, so that oil in the oil storage tank can flow to the valve core top sleeve from the inside of the valve core base, and then flows into the second cavity 52 from the second through hole on the side wall of the valve core top sleeve.

The working principle of the utility model is as follows: the spring valve core 6 is firstly placed in the cavity, and the valve wall 3 is screwed into the outer chuck 2 by the handle 4, so that the outer chuck 2 and the valve wall 3 are tightly connected through threads. Then the check valve is moved to the oil outlet of the oil storage tank by utilizing the lifting lugs 12 on the flange plate 1, bolts are placed into the first through holes 11 uniformly distributed on the flange plate 1, and the check valve is arranged at the oil outlet of the oil storage tank. Oil is filled into the oil storage tank, oil flows in from the inner part of the valve core base, flows into the second cavity 52 from the second through hole on the side wall of the valve core top sleeve through the spring, and the valve core top sleeve blocks the first cavity 51 to prevent the oil from leaking.

When oil is required to be discharged, the handle 4 is unfolded, the oil outlet rod is used for pushing the valve core top sleeve, and the valve core top sleeve slides along the third cavity 53, so that the oil in the second cavity 52 flows out of the one-way valve. When oil is not required to be discharged, the oil outlet rod is taken away, the spring valve core 6 returns to the original position under the action of oil pressure and a spring to block the first cavity 51, oil leakage is prevented, and unidirectional flow of oil is realized. And the unfolded handle 4 is retracted to the original position, so that external environmental pollutants are prevented from entering the polluted oil.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting it, and although the present utility model has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that: the technical scheme of the utility model can be modified or replaced by the same, and the modified technical scheme cannot deviate from the spirit and scope of the technical scheme of the utility model.
