Abstract
The invention discloses a kind of reducing seal ring, comprise front seal ring and rear seal ring, it is characterized in that: the rear end of described front seal ring is fixedly connected with the front end of rear seal ring; Described front seal ring and rear seal ring are the seal ring that front end external diameter is less than rear end external diameter, and the inner side surface of front seal ring is provided with some breach, the outer side surface of rear seal ring are provided with some strip projections.Improve as one, described front seal ring and rear seal ring are all the seal rings be made up of Hardmetal materials, and the number of the breach of front seal ring is 1-10, and the number of the strip projection of rear seal ring is 2-16.Structure of the present invention is simple, and reasonable in design, good sealing effect, effectively prevent moisture and dust enters, and protects machine, also effectively prevent skidding simultaneously, improves working efficiency, ensure that the normal manufacturing efficiency of enterprise.
Description
Technical field
The invention belongs to seal ring field, specifically, relate to a kind of reducing seal ring.
Background technique
Due to technological requirement, generally at organic solvent, oil, water crystallization are strong, can adopt metallic packing ring in high viscosity liquid slurry.Traditional seal ring is all the alloy of irony or aluminium, but the fusing point of iron and aluminium is lower and metal activity is stronger, therefore, the seal ring that these two kinds of materials are produced is all shorter for working life, therefore easy machinery to be had an impact, affect normally carrying out of the production order, reduce the manufacturing efficiency of enterprise.In the place that some are special, need to use reducing seal ring, but existing reducing sealing ring tightness can be poor, and often there will be skidding when rotating, affect its using effect.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned defect, provides a kind of structure simple, reasonable in design and strengthen the reducing seal ring of sealing effect.
For solving the problem, the technical solution adopted in the present invention is:
A kind of reducing seal ring, comprises front seal ring and rear seal ring, it is characterized in that: the rear end of described front seal ring is fixedly connected with the front end of rear seal ring; Described front seal ring and rear seal ring are the seal ring that front end external diameter is less than rear end external diameter, and the inner side surface of front seal ring is provided with some breach, the outer side surface of rear seal ring are provided with some strip projections.
Improve as one, described front seal ring and rear seal ring are all the seal rings be made up of Hardmetal materials, and the number of the breach of front seal ring is 1-10, and the number of the strip projection of rear seal ring is 2-16.
Improve as one, the seal ring be made up of diamondite of described front seal ring, the number of the breach of front seal ring is 4-10.
Improve as one, the number of the breach of described front seal ring is 10.
Improve as one, the seal ring be made up of diamondite of described rear seal ring, the number of the strip projection of rear seal ring is 8-14.
Improve as one, the number of the strip projection of described rear seal ring is 12.
Improve as one, the width 3-7cm of described front seal ring, and the groove gradient outside front seal ring is 10 °.
Improve as one, the thickness 3-4cm of described rear seal ring, and the groove gradient outside rear seal ring is 20 °.
Owing to have employed technique scheme, compared with prior art, the present invention is that the rear end of front seal ring is fixedly connected with the front end of rear seal ring, and front seal ring and rear seal ring are all made up of tungsten carbide alloy material.Front seal ring and rear seal ring are the seal ring that front end external diameter is less than rear end external diameter, the inner side surface of front seal ring is provided with breach, the outer side surface of rear seal ring is provided with strip projection, breach is convenient to the sealing of seal ring, and strip projection can effectively prevent from skidding.Structure of the present invention is simple, and reasonable in design, good sealing effect, effectively prevent moisture and dust enters, and protects machine, also effectively prevent skidding simultaneously, improves working efficiency, ensure that the normal manufacturing efficiency of enterprise.
Below in conjunction with the drawings and specific embodiments, the invention will be further described simultaneously.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of an embodiment of the present invention;
Fig. 2 is the Facad structure schematic diagram of an embodiment of the present invention.
In figure: 1-strip projection; Seal ring after 2-; 3-breach; Seal ring before 4-.
Embodiment
Embodiment:
As shown in Figure 1 and Figure 2, a kind of reducing seal ring, comprises front seal ring 4 and rear seal ring 2, and the rear end of described front seal ring 4 is fixedly connected with the front end of rear seal ring 2.Ordinary circumstance be adopt be welding manner, can also adopt in addition integration design.In the present invention, described front seal ring 4 and rear seal ring 2 are the seal ring that front end external diameter is less than rear end external diameter, and the inner side surface of front seal ring 4 is provided with some breach 3, and the outer side surface of rear seal ring 2 is provided with some strip projections 1.
In the present embodiment, described front seal ring 4 and rear seal ring 2 are all the seal rings be made up of Hardmetal materials, and the number of the breach 3 of front seal ring 4 is 1-10, and the number of the strip projection 1 of rear seal ring 2 is 2-16.
Consider practical application, the seal ring be made up of diamondite of described front seal ring 4, the number of the breach 3 of front seal ring is 4-10.Wherein best mode of execution is the number of breach is 10.
Consider practical application, the seal ring be made up of diamondite of described rear seal ring, the number of the strip projection of rear seal ring is 8-14.Wherein best mode of execution is the number of strip projection is 12.
In addition, in the present embodiment, the width 3-7cm of described front seal ring, and the groove gradient outside front seal ring is 10 °.The thickness 3-4cm of described rear seal ring, and the groove gradient outside rear seal ring is 20 °.
The present invention is that the rear end of front seal ring is fixedly connected with the front end of rear seal ring, and front seal ring and rear seal ring are all made up of tungsten carbide alloy material.Front seal ring and rear seal ring are the seal ring that front end external diameter is less than rear end external diameter, the inner side surface of front seal ring is provided with breach, the outer side surface of rear seal ring is provided with strip projection, breach is convenient to the sealing of seal ring, and strip projection can effectively prevent from skidding.Structure of the present invention is simple, and reasonable in design, good sealing effect, effectively prevent moisture and dust enters, and protects machine, also effectively prevent skidding simultaneously, improves working efficiency, ensure that the normal manufacturing efficiency of enterprise.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural change made under enlightenment of the present invention, and every have identical or akin technological scheme with the present invention, all belongs to protection scope of the present invention.
