摘要： A pressure relief apparatus includes a valve having a body. A shaft is rotatably disposed in the body and has an exterior end extending through the body. A plug, which may contain an internal passageway, is mounted on the shaft and is disposed in the fluid flowpath. The body is engageable with the system to expose the plug to the pressurized fluid so that the pressurized fluid acts on the plug to exert a torque on the shaft which is offset from the center line of the plug. The apparatus further includes a linkage assembly configured to translate the torque exerted on the shaft into an output force. A release device, such as a buckling pin or a magnet, is connected to the linkage assembly and is configured to release the shaft when the output force exceeds a predetermined limit. Preferably, the linkage assembly is adjustable to vary the magnitude of the output force corresponding to a given torque. A low torque seal secured in place by a retaining ring is disposed in the body to prevent fluid from leaking through the body past the plug.

摘要翻译：压力释放装置包括具有主体的阀。轴可旋转地设置在主体中并且具有延伸穿过主体的外端。可以包含内部通道的塞子安装在轴上并且设置在流体流动路径中。主体可与系统接合以将插头暴露于加压流体，使得加压流体作用在插头上以在轴上施加扭矩，该扭矩偏离插头的中心线。该装置还包括连杆组件，其构造成将施加在轴上的扭矩转换成输出力。诸如屈曲销或磁体的释放装置连接到连杆组件，并且构造成当输出力超过预定极限时释放轴。优选地，连杆组件是可调节的，以改变对应于给定扭矩的输出力的大小。通过保持环固定在适当位置的低扭矩密封件设置在主体中，以防止流体通过本体从塞子泄漏。
