Abstract

The invention belongs to a sealing element of pipe installation equipment and particularly relates to a pipe clamp sealing ring comprising an annular body made of an elastic material, wherein the annular body is annular in a natural state; the annular body can be twisted to form a saddle shape after being extruded by a pipeline and a pipe clamp in a using state; and one end of the annular body is provided with an annular raised ridge and is matched with the outer annular surface of the pipeline. The sealing ring is provided with the raised ridge, and the raised ridge can deform after the sealing ring is extruded, so that a gap between the outer wall of the pipeline and the sealing ring is filled, all parts of a joint surface of the pipeline and the sealing ring are kept in reliable interference fit, and furthermore, the sealing reliability and durability are improved.

Description

A kind of pipe clamp sealing ring

Technical field

The invention belongs to the potted component of Pipe installing equipment, be 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 joins with main pipeline The pipe clamp closed, and the joint for connecting branch, pipe clamp sandwiches on main pipeline, for joint is fixed, The through hole offered on joint and main pipeline is the most right, by fittings arm, it becomes possible to make the medium in main pipeline In inflow arm.But pipe seal part structure of the prior art is single, during with tube fit, it is impossible to Carry out good sealing, thus be easily caused joint and produce leakage.

Summary of the invention

It is an object of the invention to provide a kind of sealing preferable pipe clamp sealing ring.

For achieving the above object, the invention provides techniques below scheme: a kind of pipe clamp sealing ring, including bullet The annular body that property material is made；Under naturalness, annular body is circular；In a state of use, ring Shape body can be twisted into saddle after being extruded by pipeline and pipe clamp；Wherein one end of described annular body sets Having ring-type convex ridge, this end is for coordinating with pipeline outside ring face.

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 used for and pipe clamp On the annular slot offered match.

The method have technical effect that: the present invention arranges convex ridge on sealing ring, after sealing ring is squeezed, 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 with close Each position of seal binding face all keeps reliable interference fit, improves the reliability and durability sealed.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in detail.

In describing the invention, it should be noted that term " interior ", " outward " etc. instruction orientation or position Relation of putting is for based on orientation shown in the drawings or position relationship, and i.e. the side with pipeline 40 laminating is inner side, with The opposing side of pipeline 40 is outside, is for only for ease of the description present invention and simplifying and describes rather than instruction Or the hint device of indication or element must have particular orientation structure and an operation, therefore it is not intended that to this The restriction of invention.

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 semicirculars Clip 20, described housing 10 is provided with through hole 15, is provided with sealing ring 13 inside described through hole 15, described Being provided with one section of short tube 11 for connecting branch outside through hole 15, described short tube 11 outer end is provided with for connecting The flange 12 of arm；The two ends of described housing 10 and clip 20 are connected by bolt 30, make housing 10 He A full circle passage is formed, for sandwiching at pipeline 40 between clip 20.The present invention uses many splits Half-shell 10 is fixed by formula clip 20, uses more flexible, can effectively reduce pipe joint simultaneously The internal stress that assembling process produces, makes pipe joint be completely embedded with pipeline, reduces the risk of seal failure, carries High 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 is extruded by pipeline 40 and pipe clamp housing 10 After can be twisted into saddle；Wherein one end of described annular body is provided with ring-type convex ridge 131, this end for Pipeline 40 outer ring surface coordinates.

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, This end is for 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 is provided with bolt mounting holes.

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

Described lug 14 and circumferential reinforcement 16 interlaced arrangement on housing 10 outer wall, adjacent two lugs 14 Between be provided with shaft orientation reinforcing rib 17, this shaft orientation reinforcing rib 17 is with the circumferential reinforcement 16 on housing 10 outer wall even It is integrated.Two groups of reinforcements intersect, it is possible to improve the intensity of housing 10 further.

As shown in Figure 4,5, inside and outside two straight flanges of described housing 10, it is provided with groove 19, described recessed Groove 19 and lug 14 interlaced arrangement.Owing to reinforcement infall structure comparison is intensive, wall thickness is relatively big, unfavorable In casting, and wall thickness after offering groove 19, can be reduced, 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 of told bolt 30 Head is made up of rectangle plush copper 32 and umbrella plush copper 33 two parts, described rectangle plush copper 32 and threaded rod 31 phase Even, umbrella plush copper 33 is positioned at rectangle plush copper 32 outer end；Described rectangle plush copper 32 and the rectangle on clip 20 Hole coordinates, and is used for preventing bolt 30 from circumferentially rotating；Described umbrella plush copper 33 coordinates with rectangular opening end face, uses In preventing bolt 30 axial float.

The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, Any amendment, equivalent and the improvement etc. made within all spirit in the invention and principle, all should Within being included in the protection domain of the invention.
