CN201575139U - Novel sealing ring - Google Patents

Abstract

The utility model relates to a novel sealing ring, which has a D-shaped cross section. The sealing ring is simple in structure and reasonable in design, and the contact mode of the sealing ring and a to-be-sealed object is changed into a surface contact mode, thereby contained liquid can not easily overflow by permeating through the sealing ring when the to-be-sealed object is under the working condition of frequent movement or large-amplitude oscillation.

Description

The novel seal circle

Technical field

The utility model relates to a kind of seal ring, is specifically related to a kind of D shape seal ring.。

Background technique

At present, widely used seal ring be that sectional shape is the seal ring of O shape, its sectional shape is an O shape.Seal ring and the sealed object way of contact contacts for point, thus be in motion frequently or during the big operating conditions of shock range when sealed object, the liquid of adorning overflow through seal ring easily.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and makes seal ring become the novel seal circle that face contacts with the sealed object way of contact.

In order to achieve the above object, the technical solution adopted in the utility model is: the cross section of seal ring be shaped as D shape.

The utility model has the advantages that:

The utility model is simple in structure, reasonable in design, and makes seal ring become face with the sealed object way of contact to contact, so when sealed object was in the operating conditions that motion is frequent or shock range is big, the liquid of adorning also was not easy to overflow through seal ring.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is a sectional view of the present utility model;

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the cross section 2 of the utility model seal ring 1 is shaped as D shape.

The described D shape of the utility model model utility seal ring, its sectional shape is a D shape.Has better sealability than O-ring seals under the working environment that this D shape seal ring is frequent in motion and shock range is big.

Claims (1)

1. a novel seal circle comprises seal ring (1), it is characterized in that: the cross section (2) of seal ring (1) be shaped as D shape.
