弹簧式安全阀按结构形式来分,要分为垂锤式、杠杆式、弹簧式和先导式(脉冲式);按阀体构造来分,可分为封闭式和不封闭式两种。封闭式安全阀即排除的介质不外泄,全部沿着出口排泄到指定地点,一般用在有毒和腐蚀性介质中。对于空气和蒸汽用安全阀,多采用不封闭式安全阀。对于安全阀产品的选用,应按实际密封压力来确定。对于弹簧式安全阀,在一种公称压力(PN)范围内,具有几种工作压力级的弹簧.订货时除注明安全阀型号、名称、介质和温度外,尚应注明阀体密封压力,否则按最大密封压力供货。
珠海弹簧式安全阀,天正弹簧式安全阀适用于工作温度≤350℃的蒸汽、空气等介质的设备和管路上。A44Y弹簧全启式安全阀适用于工作温度≤300℃的空气、石油等介质的设备或管路上,作为超压保护装置。连接法兰标准PN<6.4MPa按JB/T-94系例1。PN≥6.4MPa按JB/T-94系列2标准。

根据对弹簧式安全阀开启动作特性的分析,可以得出:在外加力FW的作用下,一个安全阀从关闭到开启,再由开启到关闭的全过程中,外附加力FW的变化规律,当附加力从零逐步增加,与内压力PL×S之和正好为弹簧预紧力时,阀门微启,增大了介质作用面积S,使得用来克服弹簧预紧力的内压作用力急剧增大,其结果在瞬间减小了外附加力。从而出现第一个特征峰A。当外附加力逐渐减小而达到关闭点时,由于介质作用面积忽然减小,为保持力的平衡关系,此时,外附加力会出现瞬间回升现象,即第二个特征峰点B。上述两个特征峰点A和B是在线条件下检测安全阀开启压力、回座压力的技术依据。 |
