Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The one-way valve of a kind of adjustable pressure as shown in Figure 1-Figure 3, comprises valve body 1, joint 2, spring 3, spool 4, regulating block 5 and gear 6, described valve body 1 is axially connected to form an axis hole 7 with joint 2, described spring 3, spool 4 and regulating block 5 are all plugged in axis hole 7, its medi-spring 3 is all socketed on spool 4 with regulating block 5, and the side that regulating block 3 is withstood in one end of spring 3 makes spool 4 move to joint 2, described valve body 1 includes a chamber 8 being communicated with axis hole 7, described gear 6 is arranged in chamber 8 also rotatable, the outer side surface of described regulating block 5 is provided with tooth bar 9, described gear 6 moves with tooth bar 9 clampings regulating and controlling piece 5, also include in valve body 1 outside the switch 10 that control gear 6 rotates.Can make regulating block 5 move axially by switch 10 driven gears 6 rotations, the length (being pressure) of control spring, thus further control the pressure of spool, without dismounting, operation is very easy, and speed is fast again.
Described gear all includes gear shaft 11 in both sides Shang Xia 6, and the gear shaft 11 of described upper and lower both sides is rotatably connected with the both sides up and down of chamber 8.One end of described gear shaft 11 is fixedly connected with switch 10 through valve body 1 is rear.
The two ends of described regulating block 5 are respectively arranged with groove 12, in described groove 12, are provided with seal ring 13, and described seal ring 13 is tightly connected with axis hole, in order to avoid water enters from regulating block 5 and axis hole.
Described seal ring 13 is rubber material.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
