Abstract
The utility model discloses a Z-shaped sealing part which comprises a main body (1). An annular axial first groove (2) is positioned at one end of the main body (1), and an annular axial second groove (3) is arranged at the other end of the main body (1). The Z-shaped sealing part is good in sealing effect.
Description
Technical field
The utility model relates to a kind of Z-type Sealing.
Background technique
Sealing is to prevent fluid or material or the part of solid particle from leaking and prevent the component of the intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane.Y-shaped ring relies on its lip limit of opening to be affixed on the sealing pair coupled face.During without interior pressure, only the distortion because of procheilon produces very little contact.In the situation of sealing, and on the every bit that sealing medium contact the normal pressure that equates with pressure medium is arranged all, so lip circle bottom will be subject to axial compression, lip is subject to axial compression, contacts to broaden while contact stress increase with sealing surface.When interior pressure raise again, the distribution form of contact and size further changed, and lip cooperates tightr with sealing surface, so good airproof performance.But in special occasion, when namely two ends all needed good sealing effect, the sealing effect of Sealing was relatively relatively poor like this.
The model utility content
The technical problems to be solved in the utility model is that a kind of Z-type Sealing of good sealing effect is provided.
The technical solution of the utility model is, a kind of Z-type Sealing with following structure is provided, and comprises body, and an end of described body is provided with ring shaped axial the first groove, and the other end of described body is provided with ring shaped axial the second groove.
The one-sided cross section of described the first groove and the second groove is V-shaped, and central angle is 30～50 degree.
The central angle of described the first groove and the second groove is 40 degree.
The extended distance of described the first groove is half of end face distance of body.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the other end of described body is provided with ring shaped axial the second groove, Sealing in original end Y type sealing simultaneously like this, also establish the sealing of Y type at the other end, the similar a kind of Z-type of its cross section makes the two ends of Sealing that good sealing effect all be arranged.
Description of drawings
Accompanying drawing is the structural representation of a kind of Z-type Sealing of the present utility model.
As shown in the figure: 1, body, the 2, first groove, the 3, second groove.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, a kind of Z-type Sealing of the present utility model comprises body 1, and an end of described body 1 is provided with ring shaped axial the first groove 2, and the other end of described body 1 is provided with ring shaped axial the second groove 3.
The one-sided cross section of described the first groove 2 and the second groove 3 is V-shaped, and central angle is 30～50 degree.
The central angle of described the first groove 2 and the second groove 3 is 40 degree.
The extended distance of described the first groove 2 is half of end face distance of body 1.
