Valve opening indicating device for spray valve of pressure stabilizer

A valve opening indicating device of a pressure stabilizer spraying valve comprises a valve element, a valve rod, a locking nut and an opening indicating arrow. The valve element is connected with the valve rod, the two locking nuts are fixedly connected to the valve rod, and the opening indicating arrow is locked and fixed through the locking nuts. The design defect that an existing valve does not have visual opening indication is overcome, a judgment basis is provided for judging whether the spraying water flow changes or not due to valve opening changes, the design is simple and reliable, and the structure and the function of the valve are not affected at all. 一种稳压器喷淋阀的阀门开度指示装置，包括阀芯，阀杆，锁紧螺母和开度指示箭头；阀芯和阀杆连接，两个锁紧螺母固定连接在阀杆上，开度指示箭头通过锁紧螺母锁紧固定。本发明弥补了目前该阀门无直观的开度指示的设计缺陷，对于是否因阀门开度变化而导致喷淋水流量变化提供了判定依据，设计简易可靠，对阀门本身的结构、功能无任何影响。
