Abstract
The invention discloses an oblique inner screw-thread sealing ring. The oblique inner screw-thread sealing ring is characterized by comprising an upper sealing ring and a lower sealing ring, wherein the outer diameter of the upper sealing ring is smaller than the outer diameter of the lower sealing ring; an oblique sealing ring is connected between the upper sealing ring and the lower sealing ring; a gradient of the oblique sealing ring is 10-40 degrees; and the upper sealing ring is provided with a screw thread. As an improvement, the upper sealing ring and the lower sealing ring are made of carbon tungsten alloy; and the outer diameter of the upper sealing ring is 1-5 cm shorter than the outer diameter of the lower sealing ring. The inner side surface of the lower sealing ring is provided with a screw thread. The oblique inner screw-thread sealing ring has a simple structure, rational design and good sealing effects, and protects machines against moisture and dust efficiently; and meanwhile, the oblique inner screw-thread sealing ring also reduces maintaining and repairing difficulties, and increases work efficiency.
Description
Technical field
The invention belongs to the seal ring field, specifically, relate to a kind of inclined internal thread seal ring.
Background technique
All need to use the inclined seal ring in general machine, the material of inclined seal ring has a lot, wherein follows the in the majority of metal material with rubber.Because technological requirement, generally at organic solvent, oil, water crystallization are strong, can adopt metallic packing ring in the high viscosity liquid slurry.Traditional inclined seal ring all is the alloy of irony or aluminium, but the fusing point of iron and aluminium is lower and the metal activity is more intense, and therefore, the seal ring that these two kinds of materials are produced is all shorter working life.When carrying out sealing operation, the place of contact can produce friction in the middle of the seal ring, because the restriction of tratitional technology, its seal ring that processes can not well dispel the heat, and the metal strength of iron and aluminum alloy all can not satisfy the requirement of prior art with thermal diffusivity, therefore easily machinery is exerted an influence, influence normally carrying out of the production order, reduce the manufacturing efficiency of enterprise.
Simultaneously, existing inclined ring structure complexity, liner is easy to come off, and causes sealing effect poor, and liner has also increased mounting hardness, the difficulty that has increased maintenance and overhauled.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defective, a kind of simple in structure, reasonable in design, good sealing effect is provided and reduces maintenance and the inclined internal thread seal ring of maintenance difficulty.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of inclined internal thread seal ring is characterized in that: comprise seal ring and lower seal, the external diameter of last seal ring is less than the external diameter of lower seal; Described going up between seal ring and the lower seal is connected with the inclined seal ring, and the gradient of inclined seal ring is 10-40 °; The described seal ring of going up is provided with screw thread.
As a kind of improvement, described upward seal ring and lower seal are the seal rings of being made by diamondite, and go up the external diameter of seal ring than the external diameter weak point 1-5cm of lower seal.
As a kind of improvement, the inner side surface of described lower seal is provided with screw thread.
As a kind of improvement, described inclined seal ring is the inclined seal ring of being made by aluminum alloy material, and its gradient is 20-40 °.
As a kind of improvement, the gradient of described inclined seal ring is 35 °.
As a kind of improvement, described inclined seal ring is the inclined seal ring of being made by diamondite, and its gradient is 20-30 °.
As a kind of improvement, the gradient of described inclined seal ring is 25 °.
As a kind of improvement, the described distance that goes up between seal ring and the lower seal is 3-7cm.
As a kind of improvement, the described distance that goes up between seal ring and the lower seal is 4 or 5cm.
Since adopted technique scheme, compared with prior art, seal ring and the lower seal of going up of the present invention, the external diameter of last seal ring is less than the external diameter of lower seal; Described going up between seal ring and the lower seal is connected with the inclined seal ring, and the gradient of inclined seal ring is 10-40 °; Described going up on seal ring or the lower seal inner side surface arranges screw thread.Such design, simple in structure, reasonable in design, good sealing effect has prevented that effectively moisture and dust from entering, and has protected machine, also reduces maintenance and maintenance difficulty simultaneously, has improved working efficiency.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the cross section structure schematic representation of an embodiment of the present invention.
Among the figure: the last seal ring of 1-; 2-inclined seal ring; The 3-lower seal.
Embodiment
Embodiment:
As shown in Figure 1, a kind of inclined internal thread seal ring comprises seal ring 1 and lower seal 3, and the external diameter of last seal ring 1 is less than the external diameter of lower seal 3, be connected with inclined seal ring 2 between last seal ring 1 and the lower seal 3, the gradient of inclined seal ring is 10-40 °; The described seal ring of going up is provided with screw thread.
In the present embodiment, described upward seal ring 1 and lower seal 3 are seal rings of being made by diamondite, and go up the external diameter of seal ring 1 than the external diameter weak point 1-5cm of lower seal 3.The inner side surface of described lower seal 3 is provided with screw thread.
In addition, according to actual conditions, inclined seal ring 2 is inclined seal rings of being made by aluminum alloy material, and its gradient is 20-40 °.It is 35 ° and a kind of selection of the best is the gradient of inclined seal ring.
In the present embodiment, also have another situation, described exactly inclined seal ring is the inclined seal ring of being made by diamondite, and its gradient is 20-30 °.It is 25 ° and a kind of selection of the best is the gradient of inclined seal ring
In the present embodiment, the described distance that goes up between seal ring and the lower seal is 3-7cm.Best selection is that to go up distance between seal ring and the lower seal be 4 or 5cm.
Seal ring and the lower seal of going up of the present invention, the external diameter of last seal ring is less than the external diameter of lower seal; Described going up between seal ring and the lower seal is connected with the inclined seal ring, and the gradient of inclined seal ring is 10-40 °; Described going up on seal ring or the lower seal inner side surface arranges screw thread.Such design, simple in structure, reasonable in design, good sealing effect has prevented that effectively moisture and dust from entering, and has protected machine, also reduces maintenance and maintenance difficulty simultaneously, has improved working efficiency.
