Detailed Description
As shown in the figure, the utility model comprises a liquid injection valve sleeve 1, a one-way valve pad 2, a steel ball 3, a fixed screw sleeve 4, a one-way valve spring 6, a connecting screw 7, a cylindrical compression spring 8, a connecting nut 10 and a liquid injection port 11, wherein the liquid injection valve sleeve 1 is of a columnar hollow structure, the bottom of the liquid injection valve sleeve 1 is provided with the liquid injection port 11, the one-way valve pad 2 is arranged inside the liquid injection valve sleeve 1, the steel ball 3 is arranged above the one-way valve pad 2, the liquid injection port 11 is connected below the one-way valve pad 2 through the inner cavity of the liquid injection valve sleeve 1, the fixed screw sleeve 4 is arranged above the steel ball 3, the connecting screw 7 penetrates the liquid injection valve sleeve 1 to be connected to the fixed screw sleeve 4, the connecting screw 7 is internally provided with a cavity, the one-way valve spring 6 is arranged in the cavity, the one-way valve spring 6 penetrates the fixed screw sleeve 4 to be connected to the steel ball 3, the top of the connecting screw 7 is provided with the connecting nut 10, the cylindrical compression spring 8 is arranged outside the connecting screw 7, the cylindrical compression spring 8 is arranged between the liquid injection valve sleeve 1 and the connecting nut 10; a sealing ring 5 is arranged outside the liquid injection valve sleeve 1; and a sealing gasket 9 is arranged between the connecting nut 10 and the connecting screw rod 7.
(I) an assembly process
1. Cleaning all parts to be assembled;
2. a one-way valve pad 2 is arranged on the liquid injection valve sleeve 1, and then a steel ball 3 is arranged on the upper part of the one-way valve pad 2;
3. mounting a fixed threaded sleeve 4 on the upper part of the steel ball 3 with the parts mounted in the step 2, then mounting a one-way valve spring 6, and screwing a connecting screw rod 7;
4. further, a cylindrical compression spring 8 is mounted outside the connecting screw 7;
