特别是在一些北方地区，比如我国的东北或西伯利亚，冬天往往零下30-40度，夏天温度往往能升到30度以上，如果以额定压力和体积消耗量来计算天然气的消耗量，与实际用气量的差别是很大的。
现有的天然气表通常包括壳体(1)，所述壳体(1)内设置有计量机芯(2)，所述计量机芯(2)又设置有薄膜驱动机构(21)、叶轮(22)、传动机构(23)。所述壳体(1)的外壁设置有透明的计量视窗(3)；所述计量视窗(3)内设置有齿轮调速机构(4)，机械式计数器。
现有技术的缺陷是：由于燃气公司计算家用天然气价格是以体积用量进行计算的，受温度因素影响较大，造成居民的体积用气量与实际用气量存在较大的差异，使天然气的用气量计费不够精准。
发明内容
有鉴于现有技术的至少一个缺陷，本发明的目的是提供一种温度自适应天 然气检测装置及其控制方法，能够根据天然气的实际供气温度调整计量数据，使天然气表的检测数据更加准确。
为了达到上述目的，本发明采用如下技术方案：一种温度自适应天然气检测装置，包括壳体(1)，所述壳体(1)内设置有计量机芯(2)，所述壳体(1)的外壁设置有透明的计量视窗(3)；所述计量视窗(3)内设置有齿轮调速机构(4)，齿轮调速机构(4)的输入轴连接计量机芯(2)，其特征在于，还包括温度调整计量装置(5)，所述温度调整计量装置(5)包括计算显示装置(51)，旋转编码器(52)以及第一温度传感器(53)，所述齿轮调速机构(4)的输出轴连接所述旋转编码器(52)，旋转编码器(52)用于测量齿轮调速机构(4)输出轴的转动圈数发送给微处理器(511)，微处理器(511)将其转换成天然气的体积用量V 1，第一温度传感器(53)设置于壳体(1)上用于检测壳体(1)内的天然气实际温度T 1，所述计算显示装置(51)包括微处理器(511)和数码显示器(512)；旋转编码器(52)和第一温度传感器(53)连接微处理器(511)，微处理器(511)获取体积用量V 1和天然气实际温度T 1，将其换算成标准天然气温度T 0的体积用量V 2，微处理器(511)计算总体积消耗量并通过数码显示器(512)显示总体积消耗量。
该总体积消耗量等于原有的天然气体积消耗量加上体积用量V 2，同时微处理器(511)存储该总体积消耗量，便于下一次累计计算天然气的总体积消耗量。
上述结构设置的效果为：旋转编码器(52)将转动圈数发送给微处理器(511)，微处理器(511)内预存有齿轮调速机构(4)的输出轴转动一圈所通过的天然气体积量，乘以齿轮调速机构(4)的输出轴的转动圈数即得体积用量V 1；微处理器(511)通过旋转编码器(52)连接齿轮调速机构(4)获取天然气的体积 用量V 1，通过第一温度传感器(53)获取天然气实际温度T 1，比如-30度，然后换算成标准天然气温度T 0，比如20度的体积用量V 2，通过数码显示器(512)显示总体积消耗量。这样，天然气表能够根据天然气的实际温度调整计量数据，使天然气表的检测数据更加准确。

微处理器给电磁铁(1216)施加正反向电压拉拢和推开衔铁(1215)，控制阀芯(1212)动作。
通过上述的结构设置，通过微处理器(511)控制电磁铁(1216)通断电，即可通过阀芯(1212)控制电磁阀(121)的通断气，不需要在壳体(1)的表面开孔。
