Abstract
The invention discloses a kind of anti-corrosion type cylinder seal, including O-ring circle body, O-ring circle body thickness gradually successively decreases laterally from center, is also combined closely provided with sealing on the outside of O-ring, the sealing section is Y types, and O-ring circle body and sealing are wrapped with fluorine plastic corrosion-proof layer.The present invention is simple in construction, and O-ring circle body and Y types sealing coordinate close, good seal performance and anti-corrosion type is good, service life is long.
Description
Technical field
The present invention relates to a kind of anti-corrosion type cylinder seal.
Background technology
Sealing ring, is the immanent accessory that vital effect is played in modern industry.In hydraulic jack neck
In domain, the operating pressure of maintenance system is even more served, it is ensured that the effect of the normal work of oil cylinder.The sealing of common sealing ring
Property and corrosion resistance exist shortcoming.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of sealing and anti-corrosive properties for the deficiency for overcoming in the prior art
Can good, the anti-corrosion type cylinder seal of service life length.
The technical solution adopted for the present invention to solve the technical problems is：A kind of anti-corrosion type cylinder seal, including O-ring
Circle body, O-ring circle body thickness gradually successively decreases laterally from center, is also combined closely provided with sealing on the outside of O-ring, the sealing
Portion section is Y types, and O-ring circle body and sealing are wrapped with fluorine plastic corrosion-proof layer.
Further, in order to preferably improve sealing effectiveness, 0 type circle circle body is structure as a whole with sealing.
The beneficial effects of the invention are as follows：The anti-corrosion type cylinder seal that the present invention is provided, simple in construction, O-ring circle body and Y
Type sealing coordinates close, good seal performance and anti-corrosion type is good, service life is long.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the cross-sectional view of the present invention.
The fluorine plastic corrosion-proof of 2. sealing of 1.O types circle circle body 3. layer in figure
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of anti-corrosion type cylinder seal as shown in Figure 1, including O-ring circle body 1, the thickness of O-ring circle body 1 from center
Gradually successively decrease laterally, the outside of O-ring circle body 1 is also combined closely provided with sealing 2, and the section of sealing 2 is Y types.O-ring
Circle body 1 and sealing 2 are wrapped with fluorine plastic corrosion-proof layer 3.
Further, in order to preferably improve sealing effectiveness, O-ring circle body 1 is structure as a whole with sealing 2.O-ring circle
Body 1 and sealing 2 can be made of materials such as fourth Qing rubber, fluorubber as needed.Fluorine plastic corrosion-proof layer then serves good
Isolation antiseptic effect, extend the service life of sealing ring.
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
Personage can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to this hair
The equivalent change or modification that bright Spirit Essence is made, should all cover within the scope of the present invention.
