【技术实现步骤摘要】
本技术涉及流体压力控制阀,特别是一种集成式压力顺序阀,适合天然气气站自动顺序充气设备采用。
技术介绍
目前,在天然气充气站内部采用自动顺序充气设备来实现高、中、低压分级充气的,以避免在充气过程中因压力降低而难以保证充气压力。在现有技术中,自动顺序充气设备的顺序充气控制装置是由多个弹簧式机械顺序阀和单向阀组成,其高、中、低压管路的每组压力调节阀和单向阀是分离的,它们之间的组合又要通过三通接头、弯头、直通接头等过渡接头连接,其结构比较复杂、装配繁锁、容易产生泄漏,制造成本高,而且高、中、低压管路设置不能互换。此外,在充气设备的入口前任一设备出现危险要立即截断压缩气通路时,要分别去关多个球阀而延误时间。更为不足的是不能实现运程压力监控。
技术实现思路
为了克服已有自动顺序充气设备中顺序充气控制器存在的上述缺陷,本技术提供一种集成式压力顺序阀,它完全可以取代结构复杂的顺序充气控制装置,其结构简单、使用安全,而且能实现运程的压力监控。上述任务是以这样的方式实现的一种集成式压力顺序阀,其特征是由阀体、后压调节器、单向控制阀和进气接头组成,在阀体内沿纵向开有一条通气道,进气接头安 ...
