Description
Technical field
The utility model relates to FlexbleJoint technological systems, and in particular to a kind of FlexbleJoint leak-proof device, it is a kind of
Square type FlexbleJoint and a kind of straight barrel type FlexbleJoint.
Background technique
Heat supply pipeline thermal stretching phenomenon will occur with the raising of conveyed heat medium temperature, if this thermal stretching cannot
Access compensation, it will so that heat supply pipeline is born huge stress, or even make pipe deforming, rupture, in order to make pipeline will not be by
Stress caused by temperature change and destroyed, it is necessary to various compensators are set on pipeline, are stretched with compensating the heat of pipeline
Long and decrease eliminates the stress generated by thermal expansion.Therefore pipeline compensator keeps essential pipeline in heating system attached
Part plays an important role to the safe operation of pipe-line system.The compensation way of pipeline has natural compensation and compensator compensation, commonly uses
Compensator have shatter-proof compensator, FlexbleJoint and sleeve expansion joint etc., shatter-proof FlexbleJoint is one such.
The failure of shatter-proof FlexbleJoint has generation during pipeline pressure testing and operation.The failure occurred when pipeline pressure testing
There are mainly three types of types for form:
1. caused bracket destroys, bellows since piping temporary support is improper or the fixed bracket setting of piping is unreasonable
Excessive deformation and fail；
2. since bellows designs considered pressure or to be displaced safety affluence degree inadequate, bellows generation when pipeline pressure testing
Buckling deformation failure；
3. compensator problem of manufacturing qualities.
The failure of shatter-proof FlexbleJoint during operation is mainly shown as two kinds of forms of corrosion leakage and buckling deformation:
1. the dissection and analysis of corrosion failure bellows is found, the usual branch corrosion failure of corrosion failure and stress corrosion are opened
It splits；
2. bellows unstability has intensity unstability and structural instability two types, intensity unstability includes interior external pressure bellows plane
Unstability and external pressure bellows circumferential direction unstability；
The compensation rate of bellows depends on its fatigue life, and fatigue life is higher, and bellows unicast compensation rate is smaller, some
The fatigue life allowable of bellows is very low, will lead to that the bellows bending stress caused by being displaced is very big, and combined stress is very in this way
Height greatly reduces the stability of bellows.
Table 1 gives the relationship between unreinforced U-shaped bellows fatigue life allowable and combined stress and unicast compensation rate:
The relationship between fatigue life allowable and combined stress and unicast compensation rate of table 1
Wherein: combined stress is the comprehensive nominal stress of the bellows as caused by displacement and pressure, bellows average fatigue longevity
It orders N=10 [N], what unicast displacement provided is with the service life 1000 times reference values for object of reference allowable.
As it can be seen from table 1 the displacement of bellows unicast, but bellows simultaneously can be significantly increased by reducing fatigue life
Combined stress is also significantly increased, this will cause large effect to the strength and stability of bellows.
Shatter-proof FlexbleJoint is widely used, and is continually extended or is compressed since temperature change will cause wave, due to operating condition
Different compensator can be made to reach fatigue life allowable in a short time, cause wave cracked with physical phenomenons such as vibrations
It leaks out or gas leakage, especially shatter-proof 90 ° of corners of ripple is damaged weak spot, shatter-proof FlexbleJoint service life drops significantly
Low, summing up mainly has following characteristics and disadvantage:
1. shatter-proof FlexbleJoint manufacture is easy for installation, heat compensation amount is larger, can be used for various pressure and temperature conditions；
2. it does not need often to repair, but maintenance needs to change entire compensator, heavy workload is at high cost；
3. outer dimension is larger, occupied area is more, thus shatter-proof FlexbleJoint is limited in application by place；
4. it is compact-sized, once ripple cracking occur repairs difficulty.
Therefore, the cost of shatter-proof FlexbleJoint is repaired or replaced to shatter-proof FlexbleJoint significantly in case of leaking
Increase, while influencing the efficiency of heat supply pipeline conveying heating agent, more even because the influence of heat supply pipeline cisco unity malfunction is some heavy
Big project under construction is based on this, and the fatigue life of shatter-proof FlexbleJoint can directly or indirectly be increased while prevent by needing one kind
The device or FlexbleJoint of leakage.
