Description
Technical field
The utility model is a kind of stainless air conditioning bellows, belongs to Hardware fitting field.
Background technology
Bellows refers to the tubular elastomeric sensing element connected into foldable wrinkle piece along folding retractable direction.Bellows
Be widely used in instrument and meter, be mainly used for the measuring cell as pressure measuring instruments, convert pressure into displacement or
Power.Ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of pas to tens of MPas.Its openend is fixed, sealed end
In free state, and utilize helical spring or reed the increase elasticity of auxiliary.During work internally in the presence of pressure along pipe
Sub- elongated lengthwise, movable end is set to produce the displacement with pressure into certain relation.Movable end drives pointer directly to indicate
The size of pressure.Bellows usually combines with displacement transducer forms pressure sensor of the output for electricity, also uses sometimes
Make isolation element.Because the stretching, extension of bellows requires larger volume change, therefore its response speed is less than Bourdon tube.Ripple
Pipe is suitable to measurement low pressure.
Prior art discloses Application No.：A kind of CN201020696483.0 stainless air conditioning bellows, main bag
Include corrugated inner tube and be placed on the net of corrugated inner tube outer layer, and copper sheathing and nut located at corrugated inner tube both ends, the utility model
Corrugated inner tube is less than the length of nut from the crimp ring near termination to the length of corrugated inner tube termination, makes corrugated inner tube body
It is no longer exposed to be effectively protected outside, it will not be again squeezed in processing, transport, installation process and collide and deform damage
It is bad, and manufacturing procedure is simple, cost-effective, favorable sealing property.Prior art can not be provided simultaneously with the effect for connecting and protecting,
The longer time can not be used.
Utility model content
In view of the deficienciess of the prior art, the utility model purpose is to provide a kind of stainless air conditioning bellows, with solution
Certainly when in use, long can be corroded of usage time comes off prior art, causes leak.
To achieve these goals, the utility model is to realize by the following technical solutions：A kind of stainless air conditioning
Bellows, its structure include bellows piece, light bar segment, bellows piece enlarging, big nut, small nut, rubber blanket, rotation mouth, screw thread,
The light bar segment is inside bellows piece, and the bellows piece enlarging is located at bellows piece left and right sides, and the big nut is located at
On the right side of small nut, for the small nut on the right side of rotation mouth, the screw thread is provided with rubber blanket, institute located at rotation discharge surface, the rotation mouth
State rubber blanket and be located at thread surface, the rubber blanket is provided with rubber screw thread, pitch face, and the pitch face is on rubber screw thread
Face.
Further, the bellows piece wall thickness 0.25mm.
Further, the polished rod segment length is 150mm.
Further, the light bar segment is cylinder.
Further, the big nut is outer hexagon.
Further, the bellows piece is elastic construction.
Further, the light bar segment is alloy structure.
The beneficial effects of the utility model：Rubber screw thread is provided with by it, can first replace thread abrasion, extends ripple
The usage time of pipe, expense is saved, by that provided with pitch face, the screw thread mouth of air-conditioning can be caught on after rubber thread abrasion is complete, is made
It will not leak.
