Abstract
The utility model discloses a novel spring energy storage seal ring. The novel spring energy storage seal ring comprises a metal spring and a seal shell. A clamping groove is formed in the end face of the seal shell. The metal spring is placed in the clamping groove and is tightly clamped with the clamping groove. The metal spring of the novel spring energy storage seal ring has good elasticity, and is long in service life and good in safety. The metal spring stresses pressure, and forms outward tension so as to enable sealing lips to be closely attached to the seal clamping groove. Due to the fact that the metal spring permanently provides elasticity for the sealing lips, abrasion of the seal shell and eccentricity of a matching part can be made up, and therefore seal in a range from vacuum to low pressure is formed. In addition, system pressure can assist the metal spring in energy storage, the larger the pressure is, the fuller the attachment between the sealing lips and the seal clamping groove is, and therefore high-pressure seal is formed.
Description
[technical field]
The utility model relates to a kind of seal ring, especially relates to a kind of spring energy-storing seal ring.
[background technique]
Present Compress Spring is all to be made after spirality system by fine wire, due to Compress Spring as repair colored use the manual tools such as scissors the using process Elastic can not (elasticity that produces of this spring be vertical-type in other words toward corresponding elasticity along with the folding of scissors two arms is produced, can not be along with the folding of scissors two arms free bend, and the spring that consists of after the coiling of this fine wire spirality, due to gapped between its adjacent wire, easy tong).Nowadays, be used in all kinds of oil sealings mechanically such as motor, a kind of O-ring seal that includes is wherein arranged, be designed with annular spring on seal ring, the banding spring is housed in annular spring.When this seal ring is used on motor, under the pressure-acting of engine start running, oil in its engine cavity can rise, bump against seal ring and be bonded on engine shaft, oil sometimes will ooze out from the seal ring finedraw, and when particularly pressure was large, oil can be easy to reveal, cause unnecessary waste, therefore be necessary to improve.
[model utility content]
The technical problem that the utility model solves is to provide a kind of spring energy-storing seal ring, and metal spring sticks into the interior spring energy-storage seal ring that forms of groove of capsul.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the spring energy-storing seal ring, comprise metal spring and capsul, and be shaped with draw-in groove on described capsul end face, described metal spring is placed in draw-in groove and tightens with draw-in groove.
Further, described metal spring is U-shaped metal spring or O type metal spring, all adopts stainless steel to make.
Further, described capsul adopts the PTFE material to make, and Applicable temperature scope-268 are ℃ to+427 ℃.
The utility model compared with prior art metal spring to have good elasticity and long service life and Security better, the metal spring pressurized, form outside tension force, impel sealing lip to be close to the sealing draw-in groove, because spring forever provides elastic force to sealing lip, can make up the bias of capsul wearing and tearing and mating parts, the sealing in forming thus from the vacuum to the low pressure range.System pressure is understood the assistant metal spring energy-storage in addition, and pressure is larger, and sealing lip is more abundant with the applying of sealing draw-in groove, forms thus high pressure sealing.

[embodiment]
Below in conjunction with accompanying drawing 1-5, embodiment of the present utility model is described.
The spring energy-storing seal ring comprises metal spring 1 and capsul 2, is shaped with draw-in groove 3 on described capsul 2 end faces, and described metal spring 1 is placed in draw-in groove 3 and with draw-in groove 3 and tightens.Wherein, described metal spring 1 is U-shaped metal spring 4 or O type metal spring 5, all adopts stainless steel to make.
As extremely shown in Figure 5 in Fig. 1, described metal spring 1, there is various ways available, satisfy the seal request of different motion form, the utility model provides a kind of U-shaped metal spring 4 and o type metal spring 5, and its material is stainless steel materials, technique: 1. bending and molding after punching press, its punching press is shaped as U-shaped, as shown in Figure 2; 2. carry out consisting of metal spring 1 after the spirality coiling, as shown in Figure 3; These two kinds its major functions of design are after utilizing the plate forming pressurized, form outside tension force, impel the sealing lip on metal spring 1 to be close to sealing draw-in groove 3, because spring forever provides elastic force to sealing lip, can make up the bias of capsul 2 wearing and tearing and mating parts, the sealing in forming thus from the vacuum to the low pressure range;
Described capsul 2, can by PTFE, Filled PTEF, PEEK fill PEEK, PVDF, PPS or other high performance polymeric material is machined makes, material determines that it is applicable to from-268 ℃ to+427 ℃ seal nearly all liquid, Chemicals and gas in temperature range.And can infinitely store, not have problem of aging.Its shape can according to Consumer's usage requirement, be carried out supporting design;
The utility model is comprised of polymeric material capsul 2 and corrosion resistant stainless steel metal spring 1.Metal spring 1 pressurized forms outside tension force, impels sealing lip to be close to sealing draw-in groove 3, because spring forever provides elastic force to sealing lip, can make up the bias of capsul wearing and tearing and mating parts, the sealing in forming thus from the vacuum to the low pressure range.System pressure is understood the assistant metal spring energy-storage in addition, and pressure is larger, and sealing lip is more abundant with the applying of sealing draw-in groove, forms thus high pressure sealing.
The above is only in order to convenient explanation the utility model, and in the spiritual category that does not break away from the utility model creation, that is familiar with that those skilled in the art of this technology does various simple in a disguised form still belongs to protection domain of the present utility model with modification.
