Description

A kind of pipe clamp sealing ring

Technical field

This utility model belongs to the potted component of Pipe installing equipment, is specifically related to a kind of pipe clamp sealing ring.

Background technology

Saddle-shaped pipe joint is mainly used in external arm on official road, and this pipe joint generally comprises the pipe coordinated with main pipeline Folder, and the joint for connecting branch, pipe clamp sandwiches on main pipeline, for being fixed by joint, joint and main pipeline leaves If through hole the most right, by fittings arm, it becomes possible to make medium in main pipeline flow in arm.But it is of the prior art Pipe seal part structure is single, during with tube fit, it is impossible to carries out good sealing, thus is easily caused joint generation and lets out Dew.

Utility model content

The purpose of this utility model is to provide a kind of sealing preferable pipe clamp sealing ring.

For achieving the above object, this utility model provides techniques below scheme: a kind of pipe clamp sealing ring, including elastic material The annular body that material is made；Under naturalness, annular body is circular；In a state of use, annular body by pipeline and Saddle can be twisted into after pipe clamp extruding；Wherein one end of described annular body is provided with ring-type convex ridge, and this end is used for and pipeline Outer ring surface coordinates.

Described ring-type convex ridge is provided with at least two circles, and each loop convex ridge is arranged concentrically.

The cross sectional shape of described ring-type convex ridge is triangle, and the tip of triangle is upward.

Described ring-type convex ridge is provided with 4 circles altogether.

The edge of one end opposing with ring-type convex ridge in described annular body is provided with chamfering, and this end is for offering on pipe clamp Annular slot match.

Of the present utility model having the technical effect that this utility model arranges convex ridge on sealing ring, sealing ring is squeezed After, convex ridge can be taken advantage of a situation deformation, thus is filled with the gap between pipeline outer wall and sealing ring, makes pipeline fit with sealing ring Each position in face all keeps reliable interference fit, improves the reliability and durability sealed.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in detail.

In description of the present utility model, it should be noted that the orientation of the instruction such as term " interior ", " outward " or position relationship For based on orientation shown in the drawings or position relationship, i.e. the side with pipeline 40 laminating is inner side, the side opposing with pipeline 40 For outside, it is for only for ease of and describes this utility model and simplify description rather than instruction or the device of hint indication or element Must have particular orientation structure and operation, therefore it is not intended that to restriction of the present utility model.

The structure of sealing ring 13 is further described by the specifically used environment below in conjunction with sealing ring 13:

As shown in Figure 1, 2, a kind of pipe clamp, including a semi-tubular housing 10 and at least two Semicircular clips 20, Described housing 10 is provided with through hole 15, is provided with sealing ring 13 inside described through hole 15, be provided with outside described through hole 15 one section for The short tube 11 of connecting branch, described short tube 11 outer end is provided with the flange 12 for connecting branch；Described housing 10 and clip 20 Two ends are connected by bolt 30, make to be formed between housing 10 and clip 20 a full circle passage, for sandwiching at pipeline 40.This Utility model uses many split type clips 20 to fix half-shell 10, uses more flexible, can effectively drop simultaneously The internal stress that low pipe joint assembling process produces, makes pipe joint be completely embedded with pipeline, reduces the risk of seal failure, improve Pipe joint durability under complex working condition.

As shown in Figure 7,8, sealing ring 13 includes the annular body that elastomeric material is made；Under naturalness, annular body is Circular；In a state of use, annular body can be twisted into saddle after being extruded by pipeline 40 and pipe clamp housing 10；Described Wherein one end of annular body is provided with ring-type convex ridge 131, and this end is for coordinating with pipeline 40 outer ring surface.

Preferably, described ring-type convex ridge 131 is provided with at least two circles, and each loop convex ridge 131 is arranged concentrically.

Preferably, the cross sectional shape of described ring-type convex ridge 131 is triangle, and the tip of triangle is upward.

Preferably, described ring-type convex ridge 131 is provided with 4 circles altogether.

Preferably, the edge of one end opposing with ring-type convex ridge 131 in described annular body is provided with chamfering 132, and this end is used In matching with the annular slot 18 offered on pipe clamp.

As shown in figures 2-6, on two straight flanges of described the housing 10 and two ends of clip 20 are provided with lug 14, described lug 14 are provided with bolt mounting holes.

As shown in Fig. 3,4,6, two arc-shaped sides of the two ends of described housing 10 outer wall and middle part and clip 20 are provided with Circumference reinforcement 16, the circumferential reinforcement 16 in the middle part of housing 10 outer wall extends to the root of described short tube 11.Circumference reinforcement 16 The intensity of housing 10 can be effectively improved.

Described lug 14 and circumferential reinforcement 16 interlaced arrangement on housing 10 outer wall, be provided with axle between adjacent two lugs 14 To reinforcement 17, this shaft orientation reinforcing rib 17 is connected as a single entity with the circumferential reinforcement 16 on housing 10 outer wall.Two groups of reinforcements are mutual Intersect, it is possible to improve the intensity of housing 10 further.

As shown in Figure 4,5, groove 19, described groove 19 and lug it are provided with inside and outside two straight flanges of described housing 10 14 interlaced arrangement.Owing to reinforcement infall structure comparison is intensive, wall thickness is relatively big, is unfavorable for casting, and offers groove 19 After can reduce wall thickness, it is to avoid casting flaw occurs.

As it is shown in figure 9, the bolt mounting holes on described clip 20 is rectangular opening, the bolt head of told bolt 30 is convex by rectangle 32 and umbrella plush copper 33 two parts composition, described rectangle plush copper 32 is connected with threaded rod 31, and it is convex that umbrella plush copper 33 is positioned at rectangle 32 outer ends；Described rectangle plush copper 32 coordinates with the rectangular opening on clip 20, is used for preventing bolt 30 from circumferentially rotating；Described umbrella Plush copper 33 coordinates with rectangular opening end face, is used for preventing bolt 30 axial float.

The foregoing is only the preferred embodiment that this utility model is created, not in order to limit this utility model wound Make, any amendment, equivalent and the improvement etc. made within all spirit in this utility model creation and principle, all should comprise Within the protection domain that this utility model is created.
