Abstract

The utility model discloses a take four eyed blind flange of pull ring, by slice lid (1), pull ring (2), bolt punchhole (4) and flange stopple portion (5) component, slice lid (1) is square, hexagon or circular, pull ring (2) are the ring, vertical fixation in the geometric centre of slice lid (1) surface, flange stopple portion (5) is well empty cylindrical shape, vertical fixation in the geometric centre of slice lid (1) internal surface, bolt punchhole (4) have a plurality ofly, vertical fixation in the internal surface of slice lid (1) to distribute around flange stopple portion (5) uniformly symmetrically. The utility model discloses a four eyed blind flange had both had the bolt punchhole, had flange stopple portion again, compact structure, was difficult for dropping, to effectual, the convenient to use of protection in bolt hole and flange hole.

Description

Four eyed blind flange with draw ring

Technical field

This utility model relates to a kind of four eyed blind flange with draw ring, belongs to flange hole accessory technical field。

Background technology

Flange is generally used for the connection between various pipe fitting, it is a kind of important connector, in storage or handling process, flange hole and be very easily stained with dust and mud in bolt hole, or some little sandstones are easily accessible in flange hole and bolt hole and cause blocking, subsequent construction is caused great inconvenience。Prior art typically uses band eye blind flange or interior plunger type flange plug; although solving flange hole blockage problem; but band eye blind flange and flange hole or bolt hole are in conjunction with defective tightness; transportation is easily subject to vibrations and drops; although interior plunger type flange plug is not easy to drop; but the bolt hole protected effect that flange hole is peripheral is bad, and there is the defect filling in and extracting effort, cause use inconvenience。

Summary of the invention

The purpose of this utility model is to provide a kind of four eyed blind flange with draw ring, easily drops with eye blind flange and interior plunger type flange plug protected effect is poor, not easily fill in and the defect extracted to overcome in prior art。

For achieving the above object, the technical scheme that this utility model is taked is as follows:

Four eyed blind flange with draw ring, it is made up of lamellar lid 1, draw ring 2, bolt eyelet 4 and flange hole piston part 5, described lamellar lid 1 is square, hexagon or circle, described draw ring 2 is annulus, it is perpendicularly fixed at the geometric center of lamellar lid 1 outer surface, described flange hole piston part 5 is hollow cylindrical, it is perpendicularly fixed at the geometric center of lamellar lid 1 inner surface, described bolt eyelet 4 has multiple, be perpendicularly fixed at the inner surface of lamellar lid 1, and symmetrically, be evenly distributed in flange hole piston part 5 around。

Preferably, the edge of described lamellar lid 1 forms the sealing ring 3 bent to its inner surface。

Preferably, the outer wall of described flange hole piston part 5 also has at least one anti-skidding tough 6。

Preferably, described lamellar lid 1, draw ring 2, bolt eyelet 4 and flange hole piston part 5 are one-body molded by LDPE material。

This utility model has the advantages that

(1) four eyed blind flange of the present utility model had both had bolt eyelet; there is again flange hole piston part; compact conformation, the advantage combining aperture-type blind flange and interior plunger type flange plug, overcome aperture-type blind flange and easily drop and interior plunger type flange plug protected effect is poor, not easily fill in and the defect extracted。

(2) cover edge of four eyed blind flange of the present utility model forms reclinate sealing ring, improves waterproof sealing effect, and need not use other sealing ring。

(3) four eyed blind flange of the present utility model is obtained by LDPE material is one-body molded, environmental and durable, cost is low。

Fig. 2: the four eyed blind flange with draw ring of the present utility model structural representation under another visual angle。

Detailed description of the invention:

Below in conjunction with the drawings and specific embodiments, this utility model is described further。

As illustrated in fig. 1 and 2, four eyed blind flange with draw ring of the present utility model, by lamellar lid 1, draw ring 2, bolt eyelet 4 and flange hole piston part 5 are constituted, described lamellar lid 1 is square, hexagon or circle, described draw ring 2 is annulus, it is perpendicularly fixed at the geometric center of lamellar lid 1 outer surface, described flange hole piston part 5 is hollow cylindrical, it is perpendicularly fixed at the geometric center of lamellar lid 1 inner surface, described bolt eyelet 4 has multiple, it is perpendicularly fixed at the inner surface of lamellar lid 1, and symmetrically, it is evenly distributed in flange hole piston part 5 around, the edge of described lamellar lid 1 forms the sealing ring 3 bent to its inner surface, the outer wall of described flange hole piston part 5 also has at least one anti-skidding tough 6, described lamellar lid 1, draw ring 2, bolt eyelet 4 and flange hole piston part 5 are one-body molded by LDPE material。

Below only this utility model and embodiment thereof are described; this description is not restricted; shown in accompanying drawing is also one of embodiment of the present utility model; actual structure is not limited thereto; if those skilled in the art are enlightened by it; when creating objective without departing from this utility model, design the structure similar to this technical scheme and embodiment thereof without creationary, all should work as and belong to protection domain of the present utility model。
