CN2570581Y - Pressure-mounting type sealing disc - Google Patents

Abstract

The utility model discloses a pressure-mounting type sealing disk, which is mainly composed of disk bodies. The utility model is characterized in that each disk body is provided with a bearing groove. The utility model is reasonable in structure; in the connecting position of pipe fittings where a sealing effect is needed to be ensured, both ends of a sealing ring are respectively embedded into corresponding bearing grooves, the cross section of which is respectively trapezoidal, of the two disk bodies, pressure expansion generated by the notch end makes the sealing ring and the disk bodies attached closely, which effectively prevents the leakage on a seaming part, and the larger the pressure is, the better the leak-proof effect is.

Description

The press fixing type seal disc

Technical field:

The utility model relates to a kind of seal element, particularly relates in a kind of fluid delivery system, can prevent that piping element joint from the seal disc that leaks taking place.

Background technique:

At present, the Placement of generally using in fluid delivery system is screw thread, cutting ferrule, flange etc.And the leak-proof manner of joint mostly is and fills out pad sealing material or end face and compress sealing, and this kind mode not only material is wasteful, the installation requirement height, and implement loaded down with trivial detailsly relatively, under high temperature, high pressure and temperature variation state, the permanent stability of its sealing is low, need frequent Maintenance and Repair, very inconvenient.

Summary of the invention:

Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, at high temperature, the good press fixing type seal disc of high pressure lower seal performance.The technological scheme that its technical problem that solves the utility model adopts is, a kind of press fixing type seal disc mainly is made up of disk body, and its characteristics are: offer a cross section on the disk body and be trapezoidal holding groove.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, is skillfully constructed, guarantee the pipe fitting joint of sealing effect at needs, utilize the external force effect, the two ends of seal ring are embedded cross section corresponding on the amphidisc respectively be trapezoidal holding groove, the pressure that the notch end produces expands itself and disk body is fitted tightly, effectively prevent the leakage of seam crossing, and pressure is big more, and leak preventing effect is good more, the tool promotional value.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model sectional view;

Fig. 3 is the structural representation of the utility model when being connected with pipe fitting.

Embodiment:

Referring to Fig. 1, Fig. 2, a kind of press fixing type seal disc mainly is made up of disk body 10, offers a cross section on the disk body 10 and is trapezoidal holding groove 11.Referring to Fig. 3, anti-leak circle 20 embeds on the amphidisc 10 corresponding cross section respectively and is trapezoidal holding groove 11, and the pressure that the notch end produces expands itself and disk body 10 are fitted tightly, and effectively prevents the leakage of seam crossing, amphidisc 10 respectively with pipe fitting 30 solid weldings.

Claims (2)

1, a kind of press fixing type seal disc mainly is made up of disk body, it is characterized in that: offer a holding groove on the disk body.

2, by the described a kind of press fixing type seal disc of claim 1, it is characterized in that: the cross section of described holding groove is trapezoidal.
