Description
技术领域 technical field
本发明涉及一种安全阀的移位卡紧机构，尤其是一种用于安全阀离线校验时的卡紧机构。 The invention relates to a shift clamping mechanism of a safety valve, in particular to a clamping mechanism used for off-line calibration of a safety valve.
背景技术 Background technique
安全阀离线校验是指将安全阀从被保护设备上拆下、送校验站进行调校。安全阀离线校验时，开启压力调校和密封性能试验需要在安全阀校验台完成。目前，安全阀校验台的夹紧台均采用三爪夹紧机构，即：先将安全阀放置在配对的底部垫块上，底部垫块上有密封圈（平垫或O型密封圈），安全阀放置在有密封圈的底部垫块上后，再移动三个卡爪抱住安全阀。然后，夹紧台底部的气缸（或液压缸）活塞杆将底部垫块向上顶起。由于三个卡爪上有突出挂钩卡住安全阀底部的法兰（或底部垫块），从而使安全阀的进气法兰与底部垫块压紧，使检验介质进入安全阀内时能够做到致密不漏。 Safety valve off-line calibration refers to removing the safety valve from the protected equipment and sending it to the calibration station for adjustment. When the safety valve is calibrated offline, the opening pressure adjustment and sealing performance test need to be completed on the safety valve calibration bench. At present, the clamping platform of the safety valve calibration platform adopts a three-jaw clamping mechanism, that is, the safety valve is first placed on the matching bottom pad, and there is a sealing ring (flat pad or O-ring) on the bottom pad. , after the safety valve is placed on the bottom pad with a sealing ring, move the three claws to embrace the safety valve. Then, the cylinder (or hydraulic cylinder) piston rod at the bottom of the clamping table pushes up the bottom block. Because the protruding hooks on the three claws clamp the flange (or bottom pad) at the bottom of the safety valve, so that the inlet flange of the safety valve and the bottom pad are pressed tightly, so that the test medium can be tested when it enters the safety valve. To dense and leak-free.
但是，三爪夹紧机构存在很多弊端：首先，不仅要配置专用的卡爪、且需要加工制造专用的带倒T型凹槽的底板来固定三个卡爪并让三个卡爪能够移动；其次，每一种不同规格型号的安全阀均需要配备各自专用的底部垫块用来密封进气口；还有，安全阀需要人工（或铲车、吊车）搬到夹紧台上。上述弊端使得其工作效率低、人员劳动强度大，大口径安全阀校验时问题显得尤其突出。 However, there are many disadvantages in the three-jaw clamping mechanism: firstly, it is not only necessary to configure special claws, but also to process and manufacture special bottom plates with inverted T-shaped grooves to fix the three claws and allow the three claws to move; Secondly, each safety valve of different specifications and models needs to be equipped with its own special bottom pad to seal the air inlet; moreover, the safety valve needs to be manually (or forklift, crane) moved to the clamping table. The above-mentioned disadvantages make its work efficiency low, and the labor intensity of personnel is high. The problems in the calibration of large-diameter safety valves are particularly prominent.
