Background technique

Ball valve was come out the 1950's, along with the develop rapidly of science and technology, and the updating of production technology and product structure, in the 40 short years, having developed rapidly becomes a kind of main valve class.In the west flourishing country of industry, the use of ball valve is constantly risen year by year, in China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.

Ball valve is simple in structure, good seal performance not only, and less, lightweight in certain inside nominal diameter scope inner volume, material consumption is few, installation dimension is little, and driving moment is little, and is easy and simple to handle, easily realize fast opening and closing, is in recent ten years one of valve kind with fastest developing speed.

China Patent No. CN201589001U discloses the utility model patent that name is called glass steel ball valve handle, its method that adopts is to be provided with and a pair of projection of working and coordinating at handle body one end, described ball valve handle not only structure is ugly, carry inconvenience, and ball valve handle making material property is not strong, easily causes ball valve handle broken; China Patent No. CN202082421U discloses the utility model patent that name is called a kind of plastic double-loose-joint ball valve, the material that described ball valve and handle thereof adopt is composite polyethylene material, improved although its described ball valve handle is made material property, it is complex-shaped, and is not portable.

The model utility content

For the prior art problem, the utility model provides a kind of telescopic ball valve handle, comprise handle, handle bar and handle tail, described handle and described handle bar weld together, described handle bar bottom is provided with the first lock and pays structure, described handle tail top is provided with the first convex body, the bottom is welded with the ball valve snap close, can link together by described the first lock pair structure and described the first convex body between described handle bar and handle tail, also can select to be added with extension pipe between described handle bar and handle tail, wherein, described extension pipe top is provided with the second convex body, and the bottom is provided with the second lock and pays a structure.

Wherein, described extension pipe quantity is more than or equal to 0.

Wherein, pay docking of structure and convex body in order to realize above-mentioned lock, described the first convex body and the second convex body intermediate structure are spring structure, realize that by spring structure the first lock adhering arrangement, the second lock pay a structure and pay with the lock of the first convex body, the second convex body and separate.

Wherein, because handle after repeatedly using easily is out of shape, so the utility model is designed to hollow tube with described handle, be installed with auxiliary tube in the middle of described hollow tube, described auxiliary tube material is steel pipe, and described auxiliary tube length is preferentially selected 60cm.

According to field experience repeatedly, select 1 meter described handle tail of steel pipe manufacturing and described extension pipe.

During less than 1m, directly select described handle bar directly to be connected with the handle tail when the ball valve degree of depth, namely described handle bar bottom the first lock is paid structure and described handle tail top the first convex body lock pair.

When the ball valve degree of depth at 1m between 2m the time, select to be added with 1 extension pipe between described handle bar and handle tail, be that described handle bar bottom the first lock is paid structure and described extension pipe top the second convex body lock is paid, structure paid by described extension pipe bottom the second lock and described handle tail top the first convex body lock is paid.

When the ball valve degree of depth at 2m between 3m the time, select to be added with 2 extension pipes between described handle bar and handle tail, be that described handle bar bottom the first lock is paid structure and described extension pipe top the second convex body lock is paid, structure paid by described extension pipe bottom second lock and described extension pipe top the second convex body lock is paid, and structure paid by described extension pipe bottom the second lock and described handle tail top the first convex body lock is paid.

The rest may be inferred.

Compared with prior art, the utility model utilizes spring, improve ball valve handle by the mode that increases extension pipe, not only handsome in appearance generous, be easy to carry about with one, simultaneously can select different technological schemes according to the degree of depth of ball valve, solve ball valve and excessively deeply be difficult to the technical barrier opened because of the degree of depth, further by increase the working life of ball valve handle with steel pipe.
