Abstract

Buckle positioning ball valve handle, the connecting plate type is extended respectively to symmetry both sides in upper portion outside cast main part (2) board ear (1), simultaneously, it has on -edge groove (3) to open in cast main part (2) side, installs buckle (6) in these on -edge groove (3), in cast main part (2) inside coaxial fixed core pipe (7), cast main part (2) and core pipe (7) are sealed in the upper end and are open at the lower extreme, in this open port, core pipe (7) mouthful follow and cast main part (2) inner wall between be fixed with outstanding fender key (8). Setting and the buckle on hand, can be convenient play is fixed a position and the safety protection effect, prevents effectively that the case from rotating by oneself, simultaneously, prevents also that the valve body from being operated at will, the novel structure uniqueness, succinct easy the installation, the maintenance is portably.

Description

Snaps into position ball valve handle

Technical field

This utility model is related to the structure improved technology of ball-cock device, especially snaps into position ball valve handle.

Background technology

Ball valve is in standard GB/T21465-2008《Valve term》Defined in be：Spheroid opening and closing element is driven by valve rod, and around The valve that ball valve axis rotates.Regulation for fluid and control, wherein seal its V-type core of V-type ball valve and heap firmly Between the metal seat valve of weldering hard alloy, there is very strong shearing force, be particularly well-suited to Jie of fibre-bearing, small solid material etc. Matter.And multi-pass ball valve not only can flexibly control the switching at the interflow, shunting and flow direction of medium on pipeline, also can close simultaneously Arbitrary passage and make two other passage be connected.Ball valve typically should be horizontally mounted in the duct.Ball valve divides according to type of drive For：Pneumatic ball valve, electrical ball valve and manual ball valve.

Existing ball valve product is it sometimes appear that valve element loosens, or the other reasonses such as fluid pressure difference, leads to voluntarily rotate even Close or open the phenomenon sending out door, there is not yet the appropriate technical solution solving this problem is open.

Utility model content

The purpose of this utility model is to provide snaps into position ball valve handle, realizes convenient positioning.

The purpose of this utility model will be realized by following technical measures：In the outer symmetrical both sides in top of cannula-type body respectively Extend the plate ear connecting template, meanwhile, have edge-on groove in cannula-type body side, this edge-on groove is installed buckle；In cast Body interior coaxially fixes core pipe, and cannula-type body and core pipe open in upper end closed and in lower end, in this open port, core pipe It is fixed with prominent block key between opening's edge and cannula-type body inwall.

Especially, it is fixed with the top muscle parallel with plate ear outside cannula-type body blind end.

Especially, it is fixed with enhancing nail outside cannula-type body blind end, this enhancing nail is connected with cannula-type body positioned at plate ear Position.

Especially, cannula-type body opening is higher than core pipe opening along end face along end face.

Especially, buckle is elongated, and buckle both sides and medial surface have the strip bulge rib coordinating with edge-on groove inwall, Buckle lateral surface has protruding block.

Advantage of the present utility model and effect：Buckle in setting and handle, can easily play positioning and safety Protective effect, effectively prevents valve element from voluntarily rotating, and meanwhile, is also prevented from valve body and is arbitrarily operated, and structure novel and unique is succinctly easily pacified Dress, easy maintenance.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

Embodiment 1：As shown in accompanying drawing 1,2,3, each extend over the plate connecting template in the symmetrical both sides in the outer top of cannula-type body 2 Ear 1, meanwhile, has edge-on groove 3 in cannula-type body 2 side, installs buckle 6 in this edge-on groove 3；Internal same in cannula-type body 2 Axle fixes core pipe 7, and cannula-type body 2 and core pipe 7 open in upper end closed and in lower end, in this open port, core pipe 7 opening's edge with It is fixed with prominent block key 8 between cannula-type body 2 inwall.

In aforementioned, it is fixed with the top muscle 4 parallel with plate ear 1 outside cannula-type body 2 blind end.

In aforementioned, it is fixed with enhancing nail 5 outside cannula-type body 2 blind end, this enhancing nail 5 is located at plate ear 1 and cannula-type body 2 Connecting portion.

In aforementioned, cannula-type body 2 opening is higher than core pipe 7 opening along end face along end face.

In aforementioned, as shown in accompanying drawing 4,5, buckle 6 is elongated, and buckle 6 both sides and medial surface have and edge-on groove 3 inwall The strip bulge rib of cooperation, buckle 6 lateral surface has protruding block, increases frictional force when these protruding blocks are beneficial to stir.

In this utility model embodiment, handle overall length 147.8mm, always high 51.31mm, cannula-type body 2 external diameter 47.6mm, Strengthen 5.4mm after nail 5, two strengthen outside nail 5 along spacing 56mm.
