您要查找的是不是：
- Pressure gauges shall generally be bourdon tube or bellows type. 现场压力表应通常是波登管或波纹管型。
- Only valves such as packless diaphragm or bellows type should be used. 只能使用无衬垫膈膜阀或波纹管阀。
- The digital voltmeter has to be powered with a power supply or batteries, while the magnetoelectric type meter only needs a battery in the ohms mode. 数字式伏特计必须供以能量或者以电池组为动力,而磁电式仪表仅仅在欧姆表里需要一节电池。
- The key factors affecting the stagnation point position of L-type pipeline section are the setting position of bellows type expansion joint and the bend angle degree. 影响水平转角管段驻点位置的主要因素为波纹管补偿器设置位置、弯头角度。
- Pilot operated valves shall be considered for back pressures greater than 40% of set pressure if more favourable de-rating factors result in a valve smaller than a bellows type. 如果更多有利的非测定因子导致阀门小于波纹管类型的，对于背压大于设定压力的40%25的，应考虑辅助操作阀。
- Shaft sealing adopts single (double) face, bellow type mechanical seal, it also can adopt soft packing, is can meet sealing demands of all kinds of conditions. 轴封采用单（双）端面、波纹管等形式的机械密封，也可采用软填料密封，能适应各种条件下的密封要求；
