Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~2, a kind of one-way valve of water jet loom, including valve body 1, inner cylinder 4, spool 5, seat board 6 and bullet
Spring 7；1 upper and lower ends of valve body are respectively equipped with water inlet 2 and water outlet 9, and 5 upper end of spool is equipped with taper, and spool 5 is equipped with cavity, interior
Cylinder 4 is equipped with spring 7 and 4 lower section of inner cylinder there are 1/3-1/4 spring body, and inner cylinder 4 is placed in the cavity of spool 5, and spring 7 is set
In on seat board 6, spool 5 pushes inner cylinder 4 under effect of water pressure, and inner cylinder 4 is under the elastic force effect of spring 7 in cavity
It slides up and down, to realize the on-off of water flow, is equipped in the lower section of water inlet 2 and flows the first cavity 3, the chamber of spool 5 for liquid
Body and inner cylinder 4 constitute the second cavity 11 flowed for liquid, and the first cavity 3 of connection and the second cavity 11 are equipped on spool 5
