Description
Technical field
The utility model relates to a kind of Sealing, and more particularly, it relates to a kind of seal ring of sealing cover.
Background technique
Optical cable is a kind of communication line realizing optical signal transmission, and therefore its stability requirement is higher, and processing technology also has certain requirement, also must ensure certain mass for its production process of the special PBT of optical cable.In the production process of PBT, need to carry out modification by reactor to raw material, can application reference number be 201120334311.3 utility model patent, reactor comprises support and revolving reaction tank, the two end supports of revolving reaction tank is on support, the sidewall of revolving reaction tank is provided with discharge port and material feeding mouth, before starting the reaction, need first to vacuumize in revolving reaction tank, material feeding mouth etc. is needed to be lived by seal cap sealing, sealing cover place is in order to ensure that sealing effect can use seal ring usually, seal ring is arranged in the seal groove of sealing cover, material in revolving reaction tank makes exigent degree of vacuum when reacting, in order to sufficient sealing effect, common seal ring can give prominence to seal groove slightly, seal ring has certain elasticity, make sealing more abundant by extruding force.But in seal groove, do not have enough spaces to receive after such seal ring is squeezed; seal ring self is not also for the space that projection seal ring is stepped down; after sealing, seal ring has part can be positioned at outside seal groove; such seal ring easily damages; simultaneously; reactor uses existing this kind of seal ring; feed particulate material in revolving reaction tank is motion; particle can collide with the seal ring outside seal groove; the powder of the seal ring under collision is brought in raw material and goes, can quality of product be had influence on.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of good sealing effect and the seal ring being not easy the sealing cover of contaminated feedstock.
For achieving the above object, the utility model provides following technological scheme: a kind of seal ring of sealing cover, comprise seal ring body, described seal ring body is ring, the cross section of seal ring body is convex shape and both sides form shoulder, a described seal ring body part protrudes seal groove, and described shoulder is positioned at seal groove, and volume vacant between described shoulder and groove side wall equals the volume that seal ring body protrudes seal groove part.
Preferably, the part that seal ring body protrudes seal groove is abutting part, and described abutting part forms arc surface away from the surface of seal groove side.
Preferably, abutting part slowly broadens from arc surface to shoulder.
Preferably, be provided with in abutting part and allow bit space.
Preferably, the cross section semicircular in shape of bit space is allowed.
Preferably, the side of abutting part and shoulder place are provided with fillet structure.
By adopting technique scheme, the cross section of seal ring body is convex shape and both sides form shoulder, a seal ring body part protrudes seal groove, shoulder is positioned at seal groove, volume vacant between shoulder and groove side wall equals the volume that seal ring body protrudes seal groove part, when part oppressed after seal ring body pressurized can be moved to shoulder place, the oppressed part of seal ring body can fill the vacant place of full shoulder and seal groove, seal ring body does not have unnecessary part and is positioned at outside seal groove, guarantee can not pollute raw material, thus ensure the quality of product, rely on the owned certain elasticity of seal ring simultaneously, seal ring is made to have sufficient abutting power, ensure that good sealing.
Accompanying drawing explanation

Fig. 2 is sealing cover and sealed ring exploding schematic diagram;
Fig. 3 is sealing cover and seal ring sectional view.
Reference character: 1, seal ring body; 11, abutting part; 12, shoulder; 13, buffer space; 14, fillet structure; 15, arc surface; 2, sealing cover; 21, seal groove.
Embodiment
Be described further with reference to the seal ring embodiment of accompanying drawing to the utility model sealing cover.
A kind of seal ring of sealing cover, comprise seal ring body 1, seal ring body 1 is ring, the cross section of seal ring body 1 is convex shape and both sides form shoulder 12, seal ring body 1 part protrudes the end that seal groove 21(seal groove 21 is arranged at sealing cover 2), shoulder 12 is positioned at seal groove 21, volume vacant between shoulder 12 and seal groove 21 sidewall equals the volume that seal ring body 1 protrudes seal groove 21 part, when part oppressed after seal ring body 1 pressurized can be moved to shoulder 12 place, the oppressed part of seal ring body 1 can fill the vacant place of full shoulder 12 and seal groove 21, seal ring body 1 does not have unnecessary part and is positioned at outside seal groove 21, guarantee can not pollute raw material, thus ensure the quality of product, rely on the owned certain elasticity of seal ring simultaneously, seal ring is made to have sufficient abutting power, ensure that good sealing.
The part that seal ring body 1 protrudes seal groove 21 is abutting part 11, abutting part 11 forms arc surface 15 away from the surface of seal groove 21 side, the effect of power can be subject to when abutting part 11 will be pressed down, first be that arc surface 15 is stressed, the stress be subject to can be disperseed fully when it is stressed, be not easy when ensureing abutting part 11 pressurized to damage, ensure the working life of seal ring body 1, also ensure that sealing effect simultaneously.
Abutting part 11 slowly broadens from arc surface 15 to shoulder 12, when abutting part 11 is pressed to the filling of vacant place, abutting part 11 plays certain guiding function from arc surface 15 to shoulder 12 the formed inclined-plane that slowly broadens to part in compression, vacant place can be distributed to rapidly and uniformly, ensure that seal ring body 1 can not be positioned at outside seal groove 21 after sealing completes, ensure that raw material can not be contaminated, thus ensure quality of product; Make seal ring body 1 comparatively even at vacant punishment cloth simultaneously, be not easy to there is the situation that local is too much and stress is excessive, ensure that seal ring body 1 is not easy to damage.
Be provided with in abutting part 11 and allow bit space 13, by allowing the setting of bit space 13, can be used for unnecessary seal ring body 1 to place, preventing seal ring body 1 to be positioned at outside seal groove 21, further ensure quality of product.As preferably, allow the cross section semicircular in shape of bit space 13, have fine dispersion stress, further guarantee seal ring body 1 is not easy to damage, and meanwhile, be adds somewhat to the elasticity of abutting part 11 by such setting, thus improve the abutting power of abutting part 11, make its sealing effect better.
Side and shoulder 12 place of abutting part 11 are provided with fillet structure 14, by above setting, energy gentle movement when ensureing that abutting part 11 pressurized moves to a certain extent, there will not be the situation of turnover suddenly to occur, ensure that seal ring is not easy impaired, thus ensure the working life of seal ring.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
