Description
Technical field
The utility model relates to a kind of seal ring, specifically a kind of hydraulic giant valve rod double-layer seal rings.
Background technique
Hydraulic giant is a kind of equipment ejected by water, and can improve the flow velocity of water, hydraulic giant has many types, common are fire-fighting lance, medical high pressure water gun, engineering high pressure water gun and toy water gun.Hydraulic giant valve rod is very important parts in hydraulic giant, directly has influence on the quality of hydraulic giant.Hydraulic giant valve rod is mostly metal material, adopts seal ring to seal in hydraulic giant valve rod, prevents from leaking.The seal ring adopting rigid plastics material in present hydraulic giant valve rod, sealing effect is bad, and has larger gap between valve rod, can cause leaking, cause water resource waste more.This designs the good seal ring of a kind of sealing effect to improve this situation with regard to needing.
Model utility content
The purpose of this utility model is to provide a kind of hydraulic giant valve rod double-layer seal rings, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of hydraulic giant valve rod double-layer seal rings, comprise valve rod upper cover stabilized seal circle and valve rod lower cover stabilized seal circle, the inside, side that described valve rod upper cover stabilized seal circle and valve rod lower cover stabilized seal circle contact with each other all offers groove, described groove complements each other to form cavity, and seal ring is positioned at described cavity; Described valve rod lower cover stabilized seal circle side is provided with two-stage boss, and the side that seal ring contacts with valve rod lower cover stabilized seal circle offers the groove matched with described boss; Valve rod upper cover stabilized seal circle, seal ring and valve rod lower cover stabilized seal circle neutral position all offer through hole.
As further program of the utility model: described upper shell and lower shell body are duroplasts material, seal ring is flexible glue material.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, and production technology is simple, cheap; Upper casing and lower casing adopt duroplasts material, have good wear resistance and corrosion resistance, sturdy and durable; Seal ring adopts flexible glue to make, and has good sealing effect, by upper casing, lower casing and seal ring with the use of, thoroughly stop the situation of leaking and occur, saving water resource.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 8, a kind of hydraulic giant valve rod double-layer seal rings, comprise valve rod upper cover stabilized seal circle 3 and valve rod lower cover stabilized seal circle 1, the inside, side that described valve rod upper cover stabilized seal circle 3 and valve rod lower cover stabilized seal circle 1 contact with each other all offers groove, described groove complements each other to form cavity, and seal ring 2 is positioned at described cavity; Place seal ring 2 between valve rod upper cover stabilized seal circle 3 and valve rod lower cover stabilized seal circle 1, play the effect of secondary seal.Described valve rod lower cover stabilized seal circle 1 side is provided with two-stage boss, and the side that seal ring 2 contacts with valve rod lower cover stabilized seal circle 1 offers the groove matched with described boss; Seal ring 2 and close contact between valve rod upper cover stabilized seal circle 3 and valve rod lower cover stabilized seal circle 1, have splendid sealing effect.Valve rod upper cover stabilized seal circle 3, seal ring 2 and valve rod lower cover stabilized seal circle 1 neutral position all offer through hole, and valve rod upper cover stabilized seal circle 3, seal ring 2 and valve rod lower cover stabilized seal circle 1 fit tightly, and can not leak, saving water resource.
Further, upper shell 1 described in the utility model and lower shell body 3 are duroplasts material, and seal ring 2 is flexible glue material.There is good sealability, can not leak, and upper shell 1 and lower shell body 3 have good wear resistance and corrosion resistance, sturdy and durable.
Working principle of the present utility model is:
In use, seal ring 2 is placed in the groove of valve rod upper cover stabilized seal circle 3, then valve rod lower cover stabilized seal circle 1 and valve rod upper cover stabilized seal circle 3 is buckled together, composition double-layer seal rings, then be placed in hydraulic giant by seal ring, hydraulic giant valve rod is through the through hole in the middle of seal ring.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
