Abstract
The utility model relates to a kind of spirality silica gel sealing ring, comprise spiral circle body, described spiral circle body spiralization 4 is enclosed, 2 road circular channels are provided with in described spiral circle body, be respectively first passage and second channel, described first passage and second channel form opening towards the outer perimeter section of spiral circle body; The utility model decreases due to the impact that a large amount of motion state produces between cylinder and piston, plays better effects to the sealing under motion state, can help effectively to cushion between parts simultaneously.
Description
Technical field
The utility model relates to a kind of spirality silica gel sealing ring, belongs to connected element technical field of sealing technology.
Background technique
Seal ring starts to appear in the middle of the 19th century, makes the seal element of steamer cylinder at that time with it.Seal ring is now contained in various machinery, in the temperature, pressure and different liquids and gases media of regulation, seals under static or motion state.
In present seal ring, based on other forms of seal rings such as U-shaped circle, O RunddichtringO, y-type seal ring, hole YX RunddichtringO, square RunddichtringOs, under being mostly used in static sealing state, such as O RunddichtringO is a kind of two-way function seal element, be subject to the initial compression ability of radial direction or axis during installation, thus determine its initial sealability.And in dynamic seal process, as in the sealing of cylinder, due to the to-and-fro motion of cylinder, at cylinder and piston place, seal ring can be in a kind of hard oppression state, thus impact to seal ring, affect the working life of seal ring.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, proposes a kind of spirality silica gel sealing ring, under dynamic action, possesses buffer capacity, and the impact that the motion that can reduce cylinder causes piston improves the working life of seal ring simultaneously.
Realize the technical measures of above-mentioned purpose:
A kind of spirality silica gel sealing ring, comprise spiral circle body, described spiral circle body spiralization 4 is enclosed, and is provided with 2 road circular channels in described spiral circle body, be respectively first passage and second channel, described first passage and second channel form opening towards the outer perimeter section of spiral circle body.
Further, in the side of described spiral circle body, arc groove is provided with.
Further, the pitch on described spiral circle body bottom turns body and bottom circle body between circle is less than the pitch between other circle bodies.
The beneficial effects of the utility model: the utility model decreases between cylinder and piston, due to the impact that a large amount of motion state produces, play better effects to the sealing under motion state, can help effectively to cushion between parts simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of model utility.
Fig. 2 is the sectional view of model utility.
Embodiment
Be described in detail below in conjunction with the preferred embodiment of accompanying drawing to model utility, to make the advantage of model utility and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining made to the protection domain of model utility.
A kind of spirality silica gel sealing ring, as depicted in figs. 1 and 2, comprise spiral circle body 1, described spiral circle body 1 spiralization 4 is enclosed, 2 road circular channels are provided with in described spiral circle body 1, be respectively first passage 2 and second channel 3, described first passage 2 and second channel 3 form opening towards the outer perimeter section of spiral circle body 1.
Wherein, in the side of described spiral circle body, be provided with arc groove 4, under seal ring is subject to motion state impact, owing to forming potential energy between circle body and circle body, effectively can prevent the direct shock between seal ring, now arc groove 4 is under the effect of impact force, and the projection of arc groove 4 both sides is by crushing failure at high speed, the second buffer area is formed with this, simultaneously play the initial potential energy of spiral circle body 1 effect of double-layer bumper, better resist dynamic impulsion adding.
As shown in Figure 2, the pitch bottom described spiral circle body 1 on circle body and bottom circle body between circle is less than the pitch between other circle bodies.
In first passage 2 and second channel 3, connecting line can be embedded, while guard wire body, and reasonable line arrangement carried out to line body, improve the fly line rate of equipment line body, simultaneously to needing the device connected up to provide good approach in installation process.
Above embodiment, just model utility more preferably one of embodiment, the usual change of those skilled in the art in the aspects of model utility and replacing all should be included in the protection domain of model utility.
Claims (3)
1. a spirality silica gel sealing ring, it is characterized in that: comprise spiral circle body, described spiral circle body spiralization 4 is enclosed, 2 road circular channels are provided with in described spiral circle body, be respectively first passage and second channel, described first passage and second channel form opening towards the outer perimeter section of spiral circle body.
2. a kind of spirality silica gel sealing ring as claimed in claim 1, is characterized in that: in the side of described spiral circle body, be provided with arc groove.
