The model utility content
The purpose of this utility model is intended to solve at least one aspect of the above-mentioned problems in the prior art and defective.
One of the purpose of this utility model is to provide a kind of Sealing that improves sealability and product reliability.
Another purpose of the present utility model is to provide a kind of can be applicable to various pressure working conditions and Sealing easy to assembly.
An also purpose of the present utility model is to provide a kind of sealing configuration that comprises above-mentioned Sealing.
According to an aspect of the present utility model, it provides a kind of two-phase seal ring that is used for pressurized container, described seal ring comprises upper lip, lower lips and shoulder, described upper lip, lower lips and shoulder form similar C type profile, wherein said seal ring also comprises the metallic elastic circle, and described metallic elastic circle is arranged at the shoulder of described seal ring.
The utility model is a kind of special seal structure of utilizing new sealing principle to design.In technique scheme of the present utility model, it creates the seal ring that section is the C type with a kind of superelasticity flexible material such as rubber, be provided with a metallic elastic circle at the shoulder place of C type, superelasticity flexible material and metallic elastic circle integral die become the two-phase seal ring, and seal ring has two lips up and down.
Preferably, above-mentioned seal ring is made by one of following material: nitrile butadiene rubber, low temperature nitrile butadiene rubber, hydrorubber, fluorine rubber.
Preferably, described metallic elastic circle and the moulding of described seal ring integral die.
Preferably, described metallic elastic circle is made by stainless steel material.
Preferably, its firmness level of described seal ring is at 70-93 elastic range shore A scale.
Preferably, described upper lip is long and thin shape, and described lower lips is short and thick shape.
According on the other hand of the present utility model, it also provides a kind of sealing configuration of pressurized container, wherein said pressurized container comprises first portion and the second portion that adjoins each other, form seal clearance between described first, second part, described sealing configuration comprises the seal groove that is arranged on one of described first, second part, with aforesaid two-phase seal ring, described seal ring is installed in the described seal groove with filling and is formed at described seal clearance between described first, second part.
In a preferred embodiment, upper lip minister and approaching, its thickness is not less than 80% of seal clearance, and the angle of upper lip border line and last sealing surface is about 150 °; Lower lips is short and thick, and the angle of lower lips border line and lower sealing surface is about 110 °.
Preferably, described first portion is the blind lid of pressurized container, and described second portion is the cylindrical shell end or the flange of pressurized container.
Preferably, the cross section of described seal groove is square substantially.
Seal ring of the present utility model has good selfsealings performance, be applicable to vacuum, low pressure and high pressure, sealability raises with pressure medium and strengthens, because lip has elastic force, the back is installed under no pressure situation, rely on the reaction force of lip distortion to realize sealing, when pressure, under the pressure medium effect, make seal lip produce bigger sealing load to working surface, guarantee the reliable sealing under the pressure.In addition, owing to adopted the metallic elastic circle, it has bigger compensation ability, can overcome, installation not proper influence to sealability not enough because of the sealed groove machining accuracy; In addition, the sealing of the seal ring in the utility model can not be subjected to the aging of the wearing and tearing of working environment and seal ring and material and lose efficacy, and is suitable for rock gas, the various media of wet goods; At last, the assembling of the seal ring in the utility model is also reusable easily.
Description of drawings
From subsequently in conjunction with the accompanying drawings the description to embodiment, these of exemplary embodiment of the present utility model and/or other aspects and advantage will become apparent and be more readily understood, in the accompanying drawings:
Fig. 1 seal ring of the present utility model is assemblied in the schematic representation of pressurized container;
The structural representation of Fig. 2 seal ring of the present utility model.
Embodiment
Below by embodiment, and 1-2 in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.Following explanation to the utility model mode of execution is intended to general plotting of the present utility model is made an explanation with reference to accompanying drawing, and not should be understood to a kind of restriction of the present utility model.
As shown in Figure 1, it shows the two-phase seal ring 20 in the pressurized container of being applied to according to a kind of specific embodiment of the present utility model.Referring to Fig. 1, the pressurized container in the example comprises as the blind lid 1 of first portion with as the cylindrical shell end or the flange 3 of second portion.
Two-phase seal ring 20 interference fit are installed in the approximate square seal groove of the blind lid 1 of pressurized container, and the upper lip 24 of two-phase seal ring 20 is filled up in the cylindrical shell end or the seal clearance 22 between the flange 3 of blind lid 1 of pressurized container and pressurized container.
The back is installed not to be had under pressure or the vacuum condition, relies on the reaction force of upper lip 24 distortion to realize sealing; When pressure, under the pressure medium effect, make 24 pairs of working surfaces of upper lip of seal ring produce bigger sealing load, guarantee the reliable sealing under the pressure.Metallic elastic circle 21 has increased voltage endurance capability, even under the situation that wearing and tearing or dielectric corrosion are arranged, seal still reliable.Preferably, the upper lip thickness E is not less than 80% of seal clearance.
As shown in Figure 2, seal ring 20 comprises upper lip 24, lower lips 23 and shoulder 22, and the structure of upper lip 24, lower lips 23 and the similar C type of shoulder 22 formations, wherein at shoulder 22 places eyelet 21 is set.The material of seal ring can be used rubber, also can use other hyperelastic body.Eyelet is selected stainless steel material for use.
Although illustrated and described embodiments of the invention; yet those skilled in the art can understand; can make variation to described embodiment under the situation that does not break away from principle of the present invention and marrow, protection scope of the present invention is limited in claim and the equivalent thereof.
