Problems solved by technology

Traditional metal sealing rings are generally made of iron or aluminum alloys, but the melting points of iron and aluminum are relatively low, and the metals are relatively active and are easily corroded. Therefore, the service life of the sealing rings produced by these two materials is relatively short.
[0003] In addition, when the sealing ring is used on the shaft and needs to be replaced, if the shaft is too long or too thick, it will make the operation of the sealing ring troublesome when replacing it, thereby increasing the workload and reducing the production efficiency of the enterprise

Embodiment Construction

[0016] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to figure 1 and figure 2 , taking the O-shaped sealing ring as an example, the split-half sealing ring of the present invention is composed of two separate halves that are spliced ​​and inserted, that is, two semicircles are butted and then spliced ​​and combined to form a complete circle.

[0018] As a preferred solution, the above two separated halves are assembled into a complete sealing ring through the interfitting joint slot 1 and the limit rod 2 . The shape of spelling slot 1 and limit rod 2 is not limited to figure 1 and figure 2 As shown, it can also be trapezoidal, fan-shaped, etc., which will not be repeated here.

[0019] More preferably, the splicing slot 1 and the limit rod 2 are formed on the abutting surface of the sealing ring. Since the sealing ring needs to be coated with lubricating oil on both side...

Abstract

The invention discloses a split-type sealing ring. The sealing ring is characterized in that the sealing ring is formed by inserting combination of two separate halves, the two separate halves are assembled into the complete sealing ring through inserting grooves and limiting rods which are matched with inserting grooves, inserting grooves and limiting rods are formed on abut joint faces of the sealing ring, and the sealing ring is made of any combination of carbon tungsten alloys, silicon carbide and carbon graphite according to application requirements. The split-type sealing ring has the advantages that the structure is simple, the machining is simple, and the cost is low; the sealing ring is made of free combinations of carbon tungsten alloys, the silicon carbide and the carbon graphite according to application requirements and is high in corrosion resistance, capable of achieving different purposes, few in limitation, wide in application range and long in service life; and the split-type design is adopted, so that the sealing ring can be taken down from a long shaft or a thick shaft conveniently and quickly and is convenient to use, the workload is effectively reduced, and the production efficiency of an enterprise is improved.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a split alloy sealing ring, which belongs to the technical field of sealing. Background technique [0002] Sealing rings are used in general machines. There are many materials for sealing rings, and most of them are made of metal. Due to process requirements, metal sealing rings are generally used in organic solvents, oil / water crystallization, and high-viscosity liquid slurries. Traditional metal sealing rings are generally made of iron or aluminum alloys, but the melting points of iron and aluminum are relatively low, and the metals are relatively active and are easily corroded. Therefore, the service life of the sealing rings produced by these two materials is relatively short. . [0003] In addition, when the sealing ring is used on the shaft and needs to be replaced, if the shaft is too long or too thick, it will make the replacement of the sealing ring troublesome, thereby increasing the...
