Abstract

本发明旨在把每个阻汽排水阀的工作情况判别结果和蒸汽泄漏检测量送到计算机中，以及自动累计和分析检测结果并预报修理或更换的时间。

Description

本发明涉及判别阻汽排水阀工作情况的阻汽排水阀工作判别装置，即阻汽排水阀是否泄漏蒸汽，或者测定蒸汽的泄漏量。
阻汽排水阀被安装在蒸汽管道或者使用蒸汽的装置上，只准自动放出收集到的水而不放出蒸汽。由于燃料价格上升，需要越来越严格的监视蒸汽的泄漏。***漏蒸汽现在已成为选用阻汽排水阀的前提。蒸汽管道，在安装好以后，被严格地检查，泄漏蒸汽的阻汽排水阀必须修理或更换。
现在已开发并实际使用了多种形式的阻汽排水阀的泄漏检测器。
例如，在阻汽排水阀出口端的管道上设置检查窗，以观察其中的流体状态，并且用于温度计和振动计以测定阻汽排水阀的表面温度以及流体的流动声音。
上述不论哪种情况，只可以做到对阻汽排水阀的泄漏状态的定性观察，并不能做到对泄漏的定量测量。所以，判别泄漏的程度还须根据人的感觉。
因此，本申请人发明了简单的阻汽排水阀泄漏检测器。
检测器中的一种是日本专利申请号61-57499提出的。该发明根据以蒸汽压力作为参数的振动和蒸汽泄漏相互间的关系来确定蒸汽泄漏量。蒸汽泄漏通过一个内部装有振动传感器和温度传感器的检测器预先被测出并存贮。这个检测器装在阻汽排水阀外壳的外表面上。
日本专利申请号61-56521提出的另一个装置，设置在蒸汽供给端和阻汽排水阀之间，并且由通过喷嘴的蒸汽量和其初级端的水平面间的关系来决定蒸汽泄漏量。
上述装置能判别每个阻汽排水阀的工作情况并测出蒸汽泄漏量，但工作判别和泄漏量的测定结果的一系列准备工作，泄漏的累计以及以钱数或者***率表示的泄漏的累加总计和分析，都需要麻烦的人工操作。此外，修理或更换漏汽的阻汽排水阀要在检测后才能进行，因此不能使阻汽排水阀得到预先确定的维护。
因此，本发明的技术上目标是可以自动累计并分析检测数据并能预测修理和更换周期。
本发明揭示的解决上述问题的技术手段是能判别每个阻汽排水阀的工作情况并且通过蒸汽泄漏检测器检测和存贮蒸汽泄漏量，上述存贮的数据被送判主计算机中，该机记录并显示每个阻汽排水阀的工作判别结果和泄漏量，累计并分析所有阻汽排水阀总的泄漏量和以钱数及***率表示的泄漏，以及每个阻汽排水阀随时间变化的情况。
下面将讨论上述技术装置的功能。
每个阻汽排水阀的工作判别和蒸汽泄漏量的测定由蒸汽泄漏检测器完成。工作情况的判别和泄漏量的测量结果一旦被存贮到蒸汽泄漏检测器的存贮部分，并在检查所有阻汽排水阀后，存贮的数据被送到主计算机中。
主计算机记录并显示每个阻汽排水阀的工作情况判别结果和泄漏量，所有阻汽排水阀的必需总泄漏量的累计和分析及以钱数和***率表示的泄漏，以及每个阻汽排水阀随时间变化的泄漏量。
因此，打印，总计和检查结果的分析能自动正确地完成，阻汽排水阀的维护控制能容易地进行，同样，由于随时间变化的泄漏量被记录和显示，通过根据泄漏量预先确定修理或更换时间，可自动了解修理或更换时间。
通过条形码阅读机将贴于每个阻汽排水阀上表示阻汽排水阀号码及型号的条形码读入计算机以节省把数据输入到计算机中的人工劳动。
本发明有下列独特效果。
由于主计算机自动记录，累计和打印检测结果，可省去人工劳动，节省工作时间并且使工作标准化。
此外，由于阻汽排水阀随时间变化的蒸汽泄漏被记录和显示，可及早发现不正常的部件并修理或更换，以降低产品耗费，并节省能源。
图1是本发明的阻汽排水阀工作判别装置构造的说明框图；
下面参见图1讨论上述技术装置的一个实施例。
本发明的阻汽排水阀的工作判别装置包括蒸汽泄漏检测器1，计算显示装置2和主计算机3。
阻汽排水阀的工作检测部分10位于检测器1的一端，而条形码阅读机位于另一端。
条形码阅读机读出阻汽排水阀的号码及型号并把它们输入到计算显示装置2里的微机6中，由工作检测部分10接收的信号通过电缆12传送到计算显示装置，由放大器4放大，经模/数转换器5转换成数字，接着馈入微机6。
微机6计算是否出现泄漏以及泄漏量。在显示部分7上显示，同时，在存贮部分8中存贮反映每个阻汽排水阀的号码和型号、工作情况以及泄漏量的数据。在对所有阻汽排水阀检查以后，存贮在存贮部分8中的测量数据从数据传输器部分9通过电缆13送到主计算机3。
主计算机3记录并显示每个阻汽排水阀的工作情况以及泄漏量的判别结果，累计并分析所有阻汽排水阀的总泄漏量和以钱数和***率表示的泄漏，以及每个阻汽排水阀随时间的变化。
尽管参照附图，通过举例对本发明进行了详细描述，但是应当指出，对于本领域技术人员来说明显存在多种变化和修改。所以，除非这些变化和修改是超出本发明的权利要求范围的，否则，它们将被认为是包含于其中的。
