Each label is described as follows in figure:
1- valve body, 11- valve inlet, 12- valve export, 13- annular convex platform, 14- external screw thread, 2- spool, 3- permanent-magnetic clamp,
4- limited block, 5- adjusting gasket.
Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, a kind of permanent magnetism loaded type check-valves of the present invention, structure includes valve body 1, spool 2, permanent-magnetic clamp 3
And limited block 4.
1 right end of valve body is equipped with valve inlet 11, and the left end position opposite with valve inlet 11 is provided with valve export 12；
Coaxial annular convex platform 13, table in 13 left end of annular convex platform are provided in the inner cavity of connection valve inlet 11 and valve export 12
Face is taper type.
Above-mentioned spool 2 and permanent-magnetic clamp 3 are arranged in the inner cavity of valve body 1, and are located at left and right the two of annular convex platform 13
Side；Spool 2 is spherical shape, and radial dimension is adapted with the radial dimension of the 13 above-mentioned taper type of left end inner surface of annular convex platform, valve
Core 2 is permeability magnetic material, can select suitable valve body material according to calculation of magnetic force result；Permanent-magnetic clamp 3 is connect with valve body 1, column jacket
Face radial dimension is greater than the radial dimension of above-mentioned 13 inner surface of annular convex platform.The left side of spool 2 is arranged in above-mentioned limited block 4, with
Spool 2 matches, limit when opening for spool 2.
In the present embodiment, in order to adjust permanent-magnetic clamp 3 to the permanent magnetic attraction size of spool 2, and then control valve core 2 is initial
It opens pressure and opens retentivity, adjusting gasket 5 is preferably added between the annular convex platform 13 on valve body 1 and permanent-magnetic clamp 3.
In the present embodiment, the inner hole right end of annular convex platform 13 is counterbore shape on valve body 1, and adjusting gasket 5 and permanent-magnetic clamp 3 are embedded in counterbore
Big end in, in the present embodiment, valve body 1 be permeability magnetic material, between permanent-magnetic clamp 3 and valve body 1 by magnetic attraction connection；In addition to
