摘要
设计了一种在超声波热量表中用的测量管道。由于超声波测量管体、传感器安装孔、传感器穿线管和安装座在焊接为一体时,难以保证各部件的相互尺寸、位置精度要求,所以设计提出将以上结构一次铸造成型,并在实现一体化的基础上加装双金属测温器。由于采用一次铸造成型,所以精度高,便于大批量生产;由于加了双金属片测温器,及由其控制伸缩改变热水流量的方形板,可自动调控室内温度,可广泛用于取暖管的控制。
Designed a calorimeter using the ultrasonic measurement of pipe.As the ultrasonic measuring tube,the sensor mounting hole,the sensor threading pipe and install the seat in welding as a whole,it is difficult to ensure the various components of each size,position accuracy requirements,so the design of the above structure,a cast molding,and the integration of the based on the device to install pairs of metal temperature.As a result of a cast molding,so high precision,easy to mass production;due to increase of the bimetal temperature measurement devices,and flexible to change the water flow under the control of a square plate,can automatically control the indoor temperature can be widely used for heating tube control.
