Embodiment
With reference to Fig. 1, the utility model one-way valve embodiment is described further.
A kind of one-way valve, comprise valve pocket 7, valve seat 1, spool 5 and spring loaded 8, described spring loaded 8 is between spool 5 and valve pocket 7, described spool 5 comprises the sealed department 3 and the valve seat positioning part 2 that are wholely set successively, described valve seat positioning part 2 is sheathed in valve seat 1 and described sealed department 3 forms and is tightly connected with valve seat 1, described valve seat positioning part 2 comprises several location pieces 22, described location piece 22 around even circumferential setting and described location piece 22 all with the inconsistent formation resistance surface of valve seat 1 inwall, described resistance surface is all circular-arc setting and described circular-arc suitable with valve seat 1 inwall circular arc.
By adopting technique scheme, the part amendment that spool 5 and valve seat 1 are coordinated is several location pieces 22, location piece 22 is around even circumferential setting, between two adjacent location pieces 22, there is certain gap, ensureing under the prerequisite of the relation that closely cooperates between spool 5 and valve seat 1 inwall, reduce the area of contact between spool 5 and valve seat 1, reduce granular substance and be stuck in the possibility between spool 5 and valve seat 1, spool 5 and the stuck possibility of valve seat 1 have been reduced, this one-way valve can be worked under the environment of more coarse hydraulic oil, practicability and adaptability are improved.
