Description
Technical field
The utility model belongs to water heating pipe fittings technical field, relates to a kind of metal bellows.
Background technique
Along with the raising of people's living standard, air-conditioning has been dissolved in daily life more and more.The refrigeration of air-conditioning is the circulation by refrigerant, carries out that heat exchange realizes with space air.Air conditioner connecting pipe is used for connecting air-conditioning internal machine and outer machine, is unique passage that refrigerant circulates between interior machine and outer machine, so its significance is also just self-evident.
Air-conditioning is when work, and refrigerant flows in air conditioner connecting pipe, and air conditioner connecting pipe must keep good sealing, at the aspects such as stability of thermal conductivity, corrosion resistance, high temperature low temperature mechanical property, has corresponding requirement; Meanwhile, because air-conditioning is when mounted in order to adapt to the installation requirements in the room of various different structures, sometimes need air conditioner connecting pipe bending to arrange.
The air conditioner connecting pipe that tradition is used is that an inside and outside wall is smooth body, and such air conditioner connecting pipe resistance when curving installation is larger, and flat distortion easily occurs, making pipeline effectively be communicated with area reduces, very person also can cause Pipeline damage, occurs coolant leakage situation, affects refrigeration.Therefore, existing air conditioner connecting pipe extensively adopts bellows; For example, Chinese patent (application number 201220375164.9; Publication number CN202733233U) idle call corrugated stainless steel tubing is disclosed, comprise for connecting the stainless steel of air-conditioner host and air-conditioning outer machine and take over and be arranged on the STAINLESS STEEL NUTS that stainless steel is taken over two ends, described STAINLESS STEEL NUTS is arranged on stainless steel by snap ring block piece and takes on two ends, and described snap ring block piece is fixed on stainless steel and takes on two ends; This patent specification accompanying drawing partly discloses stainless steel in this bellows and has taken over the form that part employing is easy to bending simultaneously.In this bellows, snap ring block piece is for sealing and installation nut, yet before installing card ring blocking part, needing first its appropriateness to be broken the curved stainless steel that just can pack into takes over, increase production process, and bellows may need bending while installing an air-conditioner, in bending process, snap ring block piece was once broken curved part easy-rupturing and was caused the damage of snap ring block piece, thereby caused coolant leakage.
Therefore, someone has carried out again improving for such scheme, air-conditioning bellows after improvement has corrugated pipe segment and non-corrugated pipe segment, corrugated pipe segment and non-corrugated pipe segment are manufactured in first split, extrusion moulding one crest on end, non-corrugated pipe segment one end, nut be provided with gear along and with this gear edge coordinate with non-corrugated pipe segment crest against, the non-corrugated pipe segment the other end and corrugated pipe segment weld together.Although the bellows after improving does not need above-mentioned snap ring block piece, but easily there is following problem in such bellows in use: the sealing that is first solder joint place is difficult to be guaranteed, easily occur coolant leakage phenomenon, bellows fabricating cost is high simultaneously, has increased the burden of enterprise.And weld sealing is not fine, in use for some time, may there is the phenomenon of leaking in weld, so also can cause certain safety problem.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of engaging position stable, the metal bellows of good airproof performance.
The purpose of this utility model can realize by following technical proposal: a kind of metal bellows, comprise ripple supervisor and be arranged on the nut on ripple supervisor, on the outer wall of described ripple supervisor end, two ends, all there is the primary peak of ring-type and the secondary peak of the ring-type adjacent with primary peak, and along this ripple supervisor's axial direction, alternately there is continuously the trough of the ring-type bloating to this ripple supervisor's inner side and the crest of the ring-type that bloats to this ripple supervisor's outside between the secondary peak of end, two ends, it is characterized in that: on one end inwall of described nut near ripple supervisor, between primary peak and secondary peak, there is inside annular guide tip and nut and connect and fix by this guide tip and primary peak and secondary peak.
During making, ripple is responsible for to end, two ends secondary peak and the peak-to-peak crest of Second Wave and trough part first to complete, on ripple supervisor, pack nut into and suppress primary peak afterwards, owing to having inside annular guide tip on nut, so nut connects and fixes by this guide tip and primary peak and secondary peak.
In above-mentioned metal bellows, described crest is identical with secondary peak shape size.Be convenient to the integrated production of product.
In above-mentioned metal bellows, described primary peak is identical with secondary peak shape size.Be convenient to the integrated production of product.
In above-mentioned metal bellows, described ripple supervisor's end is provided with sealing surface and described sealing surface is provided with seal washer.To increase the sealing of product.
In above-mentioned metal bellows, described sealing surface is the end face of primary peak one end.
In above-mentioned metal bellows, described seal washer material is nitrile butadiene rubber or polytetrafluoroethylplastic plastic.
Compared with prior art, this metal bellows has the following advantages:
1, on the ripple of this bellows supervisor, there is primary peak and secondary peak has replaced traditional snap ring block piece, for with nut on guide tip connect and fix, the problem of avoiding prior art to adopt increase production process that snap ring block piece brings and snap ring block piece easy-rupturing to cause coolant leakage, has therefore simplified production process, has reduced production costs.
2, this bellows alternately forms crest and trough continuously at ripple supervisor's axial direction, thereby be easy to product bending, arranges, has improved the flexibility while using, the safety problem of also avoiding existing split type bellows to bring because of welding.
