Abstract
The utility model discloses the bellows pipe that a kind of vacuum corrugated pipe includes stainless steel, the two ends of bellows pipe are equipped with straight flange, and each straight flange is connected with an end pipe；One of end pipe is first flange, and the edge of first flange offers U-shaped mounting hole, and another end pipe is with female nut or second flange.A straight flange because of bellows pipe is connected with the first flange with U-shaped mounting hole, makes it easy for installation when using, adjustable.The flexibility of vacuum corrugated pipe of the present utility model is high simultaneously, and stroke is big, and service life is high.
Description
Technical field
The utility model is related to Bellows Technology field, more particularly to a kind of vacuum corrugated pipe.
Background technology
Metal bellows as sensing element, damper element, non-concentric axial direction actuated element, compensating element, potted component,
Valve element and pipeline connecting parts, are widely used in automatically controlling and measuring instrumentss, vacuum technique, mechanical industry, power industry,
The field such as communications and transportation and atomic energy industry.
The content of the invention
For above-mentioned deficiency, problem to be solved in the utility model is：A kind of vacuum corrugated pipe is provided, the bellows makes
With easy for installation, and flexibility is good, stroke is big, and service life is high, can keep high vacuum.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of vacuum corrugated pipe includes the bellows pipe of stainless steel, and the two ends of the bellows pipe are equipped with directly
Side, each described straight flange is connected with an end pipe；One of them described end pipe is first flange, the edge of the first flange
U-shaped mounting hole is offered, another described end pipe is with female nut or second flange.
Preferred embodiment is that the second flange is provided with bolt hole.
Preferred embodiment is that the U-shaped mounting hole in the first flange is uniformly distributed setting.
After adopting the above technical scheme, the beneficial effects of the utility model are：Due to vacuum corrugated pipe of the present utility model
Bellows pipe including stainless steel, the two ends of bellows pipe are equipped with straight flange, and each straight flange is connected with an end pipe；
One of end pipe is first flange, and the edge of first flange offers U-shaped mounting hole, and another end pipe is with internal thread
Nut or second flange.A straight flange because of bellows pipe is connected with the first flange with U-shaped mounting hole, uses it
When it is easy for installation, it is adjustable.The flexibility of vacuum corrugated pipe of the present utility model is high simultaneously, and stroke is big, and service life is high.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model vacuum corrugated pipe；
Fig. 2 is the structural representation of embodiment；
In figure：1-bellows pipe, 10-straight flange, 2-first flange, 20-U-shaped mounting hole, 3-second flange,
30-bolt hole, 4-nut.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of vacuum corrugated pipe includes the bellows pipe 1 of stainless steel, bellows pipe 1
Two ends be equipped with straight flange 10, each straight flange 10 is connected with an end pipe；One of end pipe is first flange 2, first flange 2
Edge offer U-shaped mounting hole 20, the U-shaped mounting hole 20 in the first flange 2 of the present embodiment is uniformly distributed setting；It is another
Individual end pipe is with female nut 4 or second flange 3.
Another end pipe that this implementation comes selects second flange 3, the second flange 3 to be provided with bolt hole 30, bolt hole 30
It is uniformly distributed.
Because bellows pipe 1 two ends straight flange 10 respectively with first flange 2, the second flange 3 of nut 4 or second connects,
Especially first flange 2 is provided with U-shaped mounting hole, makes it very convenient when installing.The better softness of bellows, stretches simultaneously
Amount is big, and service life is high.
The above preferred embodiment of the present utility model, is not used to limit the utility model, all in this practicality
Any modification for being made within new spirit and principle, etc. the improvement of same vacuum corrugated pipe structure etc., should be included in
Within protection domain of the present utility model.
