Abstract
The utility model relates to a bellows subassembly for the valve under the high temperature high pressure operating mode belongs to valve technical field. This bellows subassembly includes the corrugated metal pipe that the pipe wall comprises undulation wave crest and wave trough, the erection joint is connected to the one end of corrugated metal pipe, other end connection mounting flange, the one end of corrugated metal pipe extend between by crest and trough the internal diameter with the path straight tube section that the big footpath of erection joint end excircle matches, path straight tube section suit is in big footpath end is decided through withholding the hoop fastening for a short time, the other end of corrugated metal pipe by crest department extend the internal diameter with the pipeline section greatly straight that mounting flange's flange neck excircle matches, the pipeline section cover is in greatly straight the flange neck is decided through withholding the hoop fastening greatly. This for the valve corrugated metal pipe assembly not only satisfy operation requirements such as sealing performance is reliable, long -life, still satisfy harsh operating modes such as high temperature, high pressure.
Description
Technical field
This utility model relates to a kind of for valve bellows component under high temperature and high pressure condition, belongs to valve technology field.
Background technology
According to the applicant understood, the weak spot of valve-use metal bellows component is positioned at the junction of metal bellows and joint and flange, all adopts Type of Welding to be attached in the past, commissure stress, it is susceptible to tear, causes that corrugated metal pipe components lost efficacy, greatly reduce the service life of valve.Along with the progress of technology, valve is in applying working condition, design structure and has had higher requirement on service life so that valve-use metal bellows component not only to meet the instructions for uses such as sealing property reliable, long-life and be also satisfied the harsh operating mode such as high temperature, high pressure.
Utility model content
Technical problem to be solved in the utility model is, the shortcoming overcoming prior art, it is provided that a kind of for the Corrugated Tube of Valves assembly under high temperature and high pressure condition, have simple in construction, fatigue life length, the advantage such as high temperature resistant, high pressure resistant.
In order to solve above technical problem, this utility model provides a kind of High Temperature High Pressure attaching type valve-use metal bellows component.
The technical scheme that this utility model limits further is: include the metal bellows 1 that tube wall is made up of the Wave crest and wave trough that rises and falls；One end of metal bellows 1 connects erection joint 2, and the other end connects mounting flange 3；It is characterized in that: one end of metal bellows 1 is by extending the path straight length that the internal diameter bigger diameter end cylindrical with erection joint matches between crest and trough, path straight length is sleeved on bigger diameter end, is fixed by little ring 5 banding of withholding；The other end of metal bellows 1 is extended, by crest, the big footpath straight length that the neck flange cylindrical of internal diameter and mounting flange matches, and big footpath straight length is enclosed within neck flange, fixes by withholding greatly ring 4 banding.
Further, metal bellows 1 is multilamellar thin-walled body, fits tightly between layers, and ripple is " S " type.
Further, by boring section transition between bigger diameter end and the miner diameter end of erection joint, the termination of path straight length is welded in the bigger diameter end of erection joint by the sequential welding in smoothing junction with cone section.
The beneficial effects of the utility model are: this bellows component fatigue life requirements is high, if corrugated tube adopts Welding Structure and joint and Flange joint, then commissure stress, it is easy to occur weld seam to tear, thus affecting the fatigue life of assembly.And this metal bellows adopts and withholds ring and joint and Flange joint, stressed member is for withholding ring, and weld seam functions only as the effect of sealing and is not subject to the effect of power, and then force-bearing situation when improving component operation, the fatigue life of raising bellows component.

Detailed description of the invention
Embodiment 1
As it is shown in figure 1, this utility model is a kind of for valve bellows component under high temperature and high pressure condition, including the metal bellows 1 that tube wall is made up of the Wave crest and wave trough that rises and falls, one end of metal bellows 1 connects erection joint 2, and the other end connects mounting flange 3；One end of metal bellows 1 is by extending the path straight length that the internal diameter bigger diameter end cylindrical with erection joint matches between crest and trough, path straight length is sleeved on bigger diameter end, is fixed by little ring 5 banding of withholding, as shown in Figure 2；The other end of metal bellows 1 is extended, by crest, the big footpath straight length that the neck flange cylindrical of internal diameter and mounting flange matches, and big footpath straight length is enclosed within neck flange, fixes by withholding greatly ring 4 banding, as shown in Figure 3.By boring section transition between bigger diameter end and the miner diameter end of erection joint, the termination of path straight length is welded in the bigger diameter end of erection joint by the sequential welding in smoothing junction with cone section.This bellows component fatigue life requirements is high, if corrugated tube adopts Welding Structure and joint and Flange joint, then commissure stress, it is easy to occur weld seam to tear, thus affecting the fatigue life of assembly.And this utility model adopts and withholds ring and joint and Flange joint, so stressed member is for withholding ring, weld seam functions only as the effect of sealing and is not subject to the effect of power, and then force-bearing situation when improving component operation, the fatigue life of raising corrugated metal pipe components.
Metal bellows is multilamellar thin-walled body, fits tightly between layers, and owing to level is more, so wall thickness is thicker, and ripple is in " S " type, more can meet the harsh operating mode such as high temperature, high pressure.
This utility model is reasonable in design, is skillfully constructed, have simple in construction, fatigue life length, the advantage such as high temperature resistant, high pressure resistant, valve working can adapt to the harsh operating modes such as High Temperature High Pressure.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within the protection domain of this utility model requirement.
