Description
Technical field
Technical field of hydraulic oil cylinder is the utility model is related to, especially a kind of cement vertical mill oil cylinder encloses grooved seal with double O
Device.
Background technology
Cement industry Vertical Mill oil cylinder head cylinder bottom typically configuration one of static seal, due to Vertical Mill oil cylinder in use by
To greater impact, cause the pressure moment inside oil cylinder larger, easily cause oil leak, poor safety performance, while in cylinder head and cylinder
When body is installed, due to resistance, cause installation to waste time and energy, reduce operating efficiency.
Utility model content
The technical problems to be solved in the utility model is：Overcome deficiency in the prior art, there is provided a kind of install convenient, it is close
Envelope effect is good, and impact resistance, oil cylinder is not easy to cause oil leak because pressure is excessive, reduces the caused cement vertical mill oil cylinder couple O of resistance
Enclose grooved seal device.
Technical scheme is used by the utility model solves its technical problem：A kind of cement vertical mill oil cylinder encloses ditch with double O
Groove sealing device, there is cylinder body and cylinder head, described cylinder body includes path section and diameter is more than the big footpath section of path section diameter,
Big footpath Duan Chu is provided with cylinder head, and big footpath section is connected with path section by chamfering, the angle between chamfering and the inner surface of path section
For 155 °~165 °, preferably angle is 160 °, and chamfering is easy to the importing of sealing ring, without being cut to sealing ring, while
When being repaired to oil cylinder, directly the cylinder diameter of cylinder body is polished, without being repaired to cylinder head, improves operating efficiency, just
In maintenance, the junction of cylinder body and cylinder head is provided with first groove and second groove, and the first "O"-ring is provided with first groove,
Back-up ring and the second "O"-ring are installed in second groove.
Further, described cylinder head and cylinder body are fixed by screw.
The beneficial effects of the utility model are：The utility model install convenient, good sealing effect, impact resistance, oil cylinder are not easy
Cause oil leak because pressure is excessive, improve security performance, reduce the generation of resistance, easy for installation and maintenance, improve operating efficiency.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at the utility model A.
1. cylinder body in figure, 2. cylinder heads, 3. first grooves, 4. second grooves, 5. first "O"-rings, 6. back-up rings, 7. second
"O"-ring, 8. chamferings, 11. path sections, 12. big footpath sections.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of cement vertical mill oil cylinder as shown in Fig. 1~2 encloses grooved seal device with double O, has cylinder body 1 and cylinder head 2, cylinder
Body 1 includes path section 11 and diameter is more than the big footpath section 12 of the diameter of path section 11, and cylinder head 2, big footpath are provided with big footpath section 12
Section 12 is connected with path section 11 by chamfering 8, and the junction of cylinder body 1 and cylinder head 2 is provided with first groove 3 and second groove 4, and first
First "O"-ring 5 is installed in groove 3, the "O"-ring 7 of back-up ring 6 and second is installed in second groove 4.
Cylinder head 2 and cylinder body 1 are fixed by screw.
Angle between the inner surface of chamfering 8 and path section 11 is 160 °.
It is specifically independent in the hermetic unit of cylinder head 2 and cylinder body 1 increase first groove 3 and second groove 4, first groove 3
Being sealed using the first "O"-ring 5, second groove 4 is sealed using the "O"-ring 7 of back-up ring 6 and second, while is provided with chamfering, and first
The "O"-ring 7 of "O"-ring 5 and second need not be cut when installing, and when being repaired to oil cylinder, directly the cylinder diameter of cylinder body 1 is beaten
Mill, without being repaired to cylinder head 2, operating efficiency is improved, is easy to repair.
For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill
The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this
Enclose, all equivalent change or modifications made according to the utility model Spirit Essence, should all cover in protection model of the present utility model
In enclosing.
