Abstract

The utility model relates to a circlip, in particular to a sectional circlip for assembling inserts of a butterfly valve, which is an arc-shaped body composed of straight line sectional bodies and curving portions between adjacent straight line sectional bodies, two end of the circlip are respectively provided with a snap hook, the circlip is used to fix a butterfly valve insert on the valve body, ring-shaped grooves are arranged at corresponding positions on the valve body and lateral sides of the inserts, circlips are disposed in the notches of the two grooves, and the width of each groove is smaller than the diameter of the circlips. The circlip can be widely applied to various butterfly valve finished products, and has the advantages of simple mounting and dismounting, good sealing property, nice shape and the like.

Description

The segmented jump ring

Technical field

The utility model relates to a kind of jump ring, especially is applied to the segmented jump ring of butterfly valve inserts assembling.

Background technique

Butterfly valve is one of valve general in industry and the civil engineering, owing to it starts convenient rapidly, the extensive concern that is subjected to simple in structure.Inserts is the parts that prevent the prooving of valve seat and corrosion in the butterfly valve, and traditional inserts assembling generally is that this juncture has following shortcoming with many bolt lockings:

1, operational sequence is many, and assembly cost is also higher;

2, because bolt connects, on inserts threaded line sealing surface, have a plurality of screw holes, the gap around the screw hole and cause the poor sealing performance of inserts, the screw hole of inserts sealing surface causes the profile of this structure not attractive in appearance equally simultaneously.

So, the present fixing inserts of this Placement of jump ring also of no use in the butterfly valve, common jump ring is a notched annular solid, during use, a groove is arranged on workpiece, groover rot diameter equals the internal diameter of jump ring, jump ring is put in the groove, is used for blocking workpiece on one side.So this creator proposes a kind of novel segmented jump ring.

Summary of the invention

At the deficiency of existing butterfly valve inserts mounting technology, the utility model provides a kind of rational in infrastructure, good seal performance, segmented jump ring easily has been installed.

The utility model is achieved through the following technical solutions:

The utility model is formed an arc body by the curved part between straight line segment body and the adjacent straight line segment body, and the jump ring two ends are respectively equipped with grab.

Described straight line segment body is four sections, and the angle that middle two straightway bodies form is 30～60 degree.

Described straight line segment body is a rounded face with the cross section of writing pars convoluta.

This jump ring is used for the butterfly valve inserts and is fixed in valve body, and corresponding position is respectively equipped with annular groove on valve body and the inserts side, and the notch place of above-mentioned two grooves is provided with jump ring, and the width of each groove is less than the diameter of jump ring.

Described jump ring partly is provided with in the groove of valve body, and another part snaps in the groove of inserts.

The utility model can be used on the butterfly valve valve finished product of various kinds widely, and the segmented jump ring is the circle shape, and two ends are with hook.The effect with hook of jump ring two ends can make the segmented jump ring snap in housing when assembling, prevents its rotation; Jump ring cathetus segment structure, the assembling back forms elastic force in the housing groove, prevent that inserts from dropping out.

The utlity model has following useful effect:

1, cost is lower, and mounting or dismounting are simple: traditional inserts assembling generally is with many bolts lockings, and this segmented jump ring has only just replaced many bolts with single line shape thing, and less during the rigger, and material has certain advantage with assembling on the time cost.

2, good seal performance: traditional inserts has a plurality of screw holes owing to be bolts assemblies on inserts threaded line sealing surface, sealability is more bad, and new segmented jump ring does not have the hole on inserts threaded line sealing surface, only in the side groove is arranged, and sealability is better

3, appearance looks elegant: owing to cancelled traditional Bolt Connection, on inserts threaded line sealing surface, do not have the hole, kept the conformity of threaded line sealing surface.

Wherein, 1, jump ring, 101, the straight line segment body, 102, curved part, 103, grab,

2, valve body, 201, valve body recess,

3, inserts, 301, the inserts groove

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: structure such as Fig. 1, Fig. 2, shown in Figure 3, the utility model is formed an arc body by the curved part 102 between straight line segment body 101 and the adjacent straight line segment body, and jump ring 1 two ends are respectively equipped with grab 103.Straight line segment body 101 is four sections, and the angle that middle two straightway bodies form is 30～60 degree.The cross section of straight line segment body 101 and curved part 102 is a rounded face.As shown in Figure 2, this jump ring 1 is used for butterfly valve inserts 3 and is fixed in valve body 2, corresponding position is respectively equipped with annular valve body groove 201 and inserts groove 301 on valve body 2 and inserts 3 sides, and the notch place of above-mentioned two grooves is provided with jump ring 1, and the width of each groove is less than the diameter of jump ring.Jump ring 1 part is provided with in the valve body recess 201, and another part snaps in the inserts groove 301.

The segmented jump ring that a kind of novel butterfly valve inserts assembles, this segmented jump ring has cost low, and sealability is better, and appearance looks elegant is installed and removed characteristics such as simple.Can be used in widely on the butterfly valve valve finished product of various kinds.The segmented jump ring is the circle shape, and two ends are with hook.

1, two ends effect with hook can make the segmented jump ring snap in housing when assembling, prevents its rotation.

2, straightway structure, the assembling back forms elastic force in the housing groove, prevent that inserts from dropping out.

The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.

Claims

1, segmented jump ring is characterized in that: form an arc body by the curved part between straight line segment body and the adjacent straight line segment body, the jump ring two ends are respectively equipped with grab.

2, segmented jump ring according to claim 1 is characterized in that: described straight line segment body is four sections, and the angle that middle two straightway bodies form is 30～60 degree.
