Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, embodiments of the present invention are described in detail below, and the embodiments of the present invention are described in detail below clearly and completely.
The terminology used herein is for the purpose of describing embodiments and is not intended to be limiting and/or restricting the invention.
For example, expressions such as "in a certain direction", "along a certain direction", "axial direction", "orthogonal", "axial line", "relative", "front-back-left-right" and the like indicate relative or absolute arrangements, and indicate not only such arrangements in a strict sense but also a state of being relatively displaced with a tolerance or an angle or a distance to the extent that the same function can be obtained.
As shown in fig. 1 to fig. 3, the novel sealing structure in this embodiment is suitable for the field of valves, and is used as a sealing element in a valve, and is mainly formed by combining a first sealing body 10 and a second sealing body 20, where the first sealing body 10 is made of a polytetrafluoroethylene material, and has high chemical stability and chemical inertness, and has a small friction force, and the second sealing body 20 is made of rubber, so as to provide a good sealing effect.
Specifically, the sealing body one 10 is formed by integrally molding the sealing portion 100 and the supporting portion 200, and both the sealing portion 100 and the supporting portion 200 are annular structures.
For easy understanding, an outer side surface 110 and an inner side surface 120 are set on the sealing portion 100, the supporting portion 200 is uniformly arranged around the outer side surface 110 of the sealing portion 100, one end surface of the supporting portion 200 is flush with an adjacent end surface of the sealing portion 100, and the other end surface of the supporting portion 200 in the opposite direction is spaced from the other end surface of the sealing portion 100 in the opposite direction, that is, the width of the supporting portion 200 is smaller than that of the sealing portion 100, and the sealing body one 10 is in a substantially L-shaped structure in cross section.
Here, the support portion 200 is understood to be vertical for stable support, and the sealing portion 100 is correspondingly horizontal for sealing.
And the outer side surface 110 of the sealing part 100 is in a horizontal or concave arc surface-shaped structure, specifically, a part of the outer side surface 110 which is not connected with the supporting part 200 is used for being sleeved in the sealing body two 20 for close connection, namely, the distance between the other end surface of the supporting part 200 and the other end surface of the sealing part 100 is larger than or equal to the wall thickness of the sealing body two 20, generally equal to that, namely, the width of the part which is not connected with the supporting part 200 is consistent with the wall thickness of the sealing body two 20, and after the sealing body two 20 is configured, the arc top of one side is attached to the end surface of the supporting part 200.
Accordingly, the outer diameter of the support portion 200 is preferably equal to or slightly smaller than the outer diameter of the sealing body 20.
The inner side surface 120 is composed of three sections of a first medium section 121, a second sealing section 122 and a third connecting section 123 which are sequentially arranged, the second sealing section 122 is horizontally arranged and is parallel to the axis of the sealing part 100, the first medium section 121 and the third connecting section 123 are both obliquely arranged towards the direction of the outer side surface 110, namely the second sealing section 122 is positioned at the center of the inner side surface 120, the first medium section 121 and the third connecting section 123 are correspondingly and symmetrically positioned at two side positions of the inner side surface 120 and correspondingly extend to two opening positions of the sealing part 100, and a horn-shaped structure which is generally in a horn shape and gradually reduces from outside to inside is formed.
Here, the first medium segment 121 is directed toward the low pressure side of the medium, the third connecting segment 123 is directed toward the high pressure side of the medium, and the second sealing segment 122 is used to hold a part to be sealed, i.e., a sealed object, to perform a sealing function.
The structure of the L-shaped sealing body I10 enables the friction resistance between the whole body in motion and the sealed piece to be smaller than that of the traditional combined sealing, and meanwhile, the sealing effect is ensured, and the L-shaped sealing body I can be widely applied to the field of valves.
The present invention describes preferred embodiments, including the best mode of carrying out the present invention as known to those skilled in the art. Of course, variations of these preferred embodiments will be apparent to those skilled in the art. The present invention contemplates that skilled artisans can employ such variations as appropriate, and the present invention teaches that the invention can be practiced otherwise than as specifically described herein. Accordingly, this invention includes all modifications encompassed within the spirit and scope of the invention as defined by the claims. Moreover, unless stated otherwise or clearly contradicted by context, the present disclosure includes any such elements and all possible variations thereof.
