application : instrument . Thermometer bellows coupling bellows fuel level gauge valve copper bellows no sealing high pressure bellows vacuum bellows sensor bellows vacuum switch
types of joints : 1, both ends are external joints WW type
2, both ends are internal joints NN type
3, one end is external joints , the other with bottom WDtype
4, both ends are side cut from the trough QdQd type
Bellows:
1) Balances and compensates to prevent displacement or vibrations in extreme temperatures, pressure, or thrust.
2) Used extensively in all facets of the high-tech steel industry as well as other industries.
3) Have good flexibility and handle extreme temperature and pressure well.
4) They can play an important role in hose reciprocating motion, thermal expansion absorption, vibration absorption and adjusting compound tube center.
Metal bellows is also usually used in vibration isolating and noise reducing besides being used as thermal displacement compensating device
the bellows is tight structure , low cost , corrosion resisting , great elasticity , low stiffness , allowing fatigue strength span up to 1000 times
