Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Example 1:
as shown in fig. 1, 2, and 3, in this embodiment, the novel check valve includes a valve seat 3, a guide pipe 9 disposed on the valve seat 3, and a valve core 6 slidably connected to the guide pipe 9, a plurality of valve seat overflowing holes 10 are disposed on the valve seat 3, a conical surface with a small end facing outward is disposed at a free end of the valve core 6, and an elastic support structure is disposed between the valve core 6 and the valve seat 3.
The valve seat 3 is arranged on the installation seat 2, and the valve core 6 is arranged in a matching way with the installation seat overflowing hole 13 in the installation seat 2. Inside fluid got into mount pad 2 from mount pad oil inlet 11, crossed discharge orifice 13 department at the mount pad and exert pressure to case 6, under the pressure effect, case 6 compression spring made the mount pad cross discharge orifice 13 and opened, fluid passed the mount pad and crossed discharge orifice 13, can cross discharge orifice 10 two directions outflow from the mount pad oil-out 12 and the disk seat of check valve side, realized the function of following the check valve side and producing oil, can increase the application scope of check valve. The mounting seat oil outlet 12 or the valve seat overflowing hole 10 can be closed as required to realize the function of one-way oil outlet.
The scheme saves the shell structure of the check valve, can make the check valve structure simpler, is convenient to process and manufacture, reduces the production cost, can also reduce the whole weight of the check valve, and is favorable for reducing the weight of the whole check valve after installation.
The free end of the valve core 6 is designed into a conical surface with the small end facing outwards, so that the sealing strength of the valve core 6 and the overflowing hole 13 of the mounting seat can be improved.
Example 2:
