反拱鳄齿形片是由单体膜片和鳄齿环构成的复合式片，单体膜片拱面受压，失稳翻转后沿鳄齿环切开，泄放压力，从而起到保护系统的作用。
  适用范围：适用于中、低压、有脉动压力的全真空、气态介质等工况。
  产品特点：
  1）大工作压力可达压力的90%，可适用于有脉动压力的工况，抗疲劳性能好；
  2）片后没有碎片，可与安全阀串联使用；
  3）受鳄齿环强度限制，压力不能太大。
  产品主要型式：
  1）反拱鳄齿形片YE；
  2）反拱鳄齿形焊接式片YEJ：是将片与夹持器焊接为一个整体，密封性好，压力不受裝夹因素的影响，使用方便。
  适用夹持器型号：YJE
The reverse tooth-ring bursting disc is a complex one consisting of mono-membrane and tooth-ring. It will be cut along with the tooth-ring when the mono-membrane is instable and overturned due to the pressure on the arch face so that the pressure can be released for system protection.
Scope of application: operating mode of vacuum and gas media with middle, low and fluctuating pressure.
Characteristics of the product:
  1) The maximum operating pressure can reach 90% of the bursting pressure, which is applicable in the existence of fluctuating pressure and has a good performance in fatigue resistance.
1) The safety valves can be connected in series due to no fragments after the explosion.
2) The bursting pressure is limited by the intensity of the tooth-ring.  
Major type:
1）Reverse tooth-ring bursting disc YE
2）Reverse tooth-ring welded bursting disc YEJ: the bursting disc and the holder is welded as a whole, which has a good sealing performance and is user-friendly because the bursting pressure is unaffected by clamping motions.
Applicable holder type:：YJE
