Description
Technical field
The utility model relates to Bellows Technology fields, more particularly to a kind of full-automatic sensing bellows.
Background technique
Ripple tube sensor, that is, bent beam structure sensor, using metal bellows welded seal form, inside is filled with lazy
Property gas.Ripple tube sensor medium wave line pipe has elasticity, and displacement is generated under pressure, axial force, cross force or Moment.
Load value needed for making metal bellows generate unit displacement becomes the rigidity of metal bellows, in bellows weighing sensor
In, in order to reduce, thing of weighing generates displacement to bellows, it is desirable that the rigidity of bellows is larger, and existing metal bellows
Rigidity itself is smaller, influences whether the range of bellows weighing sensor.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art provides a kind of full-automatic sensing
Bellows.
In order to solve the above technical problems, the technical solution of the utility model is as follows：
A kind of full-automatic sensing bellows, including tube body, tube body include bellows and helical spring, and the surface of bellows is equal
It is even to be provided with wave crest, spiral helicine trough is formed between two groups of adjacent wave crests, helical spring is coiled in trough and and trough
Move towards identical, bellows wave crest it is interior it is intracavitary be provided with elastic piece identical with waveform shape, elastic piece is fitted tightly over wave
The inner surface at peak.
Technical effect：Helical spring is coiled in trough by the utility model, not only can carry out axial position in bellows
Power is provided when shifting, improves the axial rigidity of bellows, and since helical spring itself has certain bending stiffness, it can
To improve the bending stiffness of bellows；In addition, can be propped up the tube wall of trough two sides when bellows carries out axial displacement
Support and buffering reduce the pressure that the tube body of the outer trough two sides of bellows is subject to, and reduce fatigue crack at the outer trough of bellows
It generates, to improve the service life of bellows.
Further, the straight line where elastic piece both ends is axial parallel with tube body, and elastic piece both ends are connected by spring.
A kind of preceding full-automatic sensing bellows, bellows includes metal-based layer, buffer layer and wearing layer, by ripple
Tube outer surface is followed successively by wearing layer, metal-based layer and buffer layer to bellows inside surface.
A kind of preceding full-automatic sensing bellows, metal-based layer are made of stainless steel, and buffer layer is made of HDPE, resistance to
Grind layer by ultrahigh molecular weight polyethylene at.
A kind of preceding full-automatic sensing bellows, wearing layer and buffer layer pass through hot melt and metal-based layer welding.
Soldering is coated on the contact surface of a kind of preceding full-automatic sensing bellows, helical spring and bellows trough
Agent, helical spring is by soldering integral solder in the outer surface of bellows.
The utility model has the beneficial effects that：
（1）The utility model intracavitary setting elastic piece in wave crest, is displaced, tube wall is squeezed by external force in bellows
When, elastic piece can be supported tube body, both play the role of reinforcing, effectively increase the rigidity of bellows, and can play
The buffer function of power greatly reduces external force to the active force of ripple tube wall, improves the anti-pressure ability of bellows, avoid wave
Fatigue crack is generated when line pipe is significantly displaced at wave crest；Elastic piece both ends are connected by spring, improve elastic piece deformation institute
The power needed, further improves the rigidity of bellows；
（2）In the utility model, bellows is made of metal-based layer, buffer layer and wearing layer, and bellows is being displaced
When, buffer layer can play buffer function to metal-based layer, extend the service life of metal-based layer；Wearing layer can be to ripple
Tube outer surface is protected, and avoids wearing ripple tube outer surface due to contacting with each other between ripple, can also be avoided
Ripple tube outer surface contacts with helical spring and generates abrasion, to extend the service life of bellows.
