YQYG-224型減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)器是由黃銅(tong)制成。兩級(ji)減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)系(xi)‘的(de)構造基本相似，均由活(huo)門頂桿、調(diao)壓(ya)(ya)(ya)(ya)彈(dan)簧、彈(dan)性薄膜(mo)裝置、減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)門等零(ling)部件組(zu)成。*級(ji)減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)系(xi)統主要用于將 高壓(ya)(ya)(ya)(ya)氣(qi)體自動降(jiang)為(wei)高壓(ya)(ya)(ya)(ya)氣(qi)體，降(jiang)至壓(ya)(ya)(ya)(ya)力為(wei)實(shi)際使(shi)用壓(ya)(ya)(ya)(ya)力，然后送入(ru)第二(er)級(ji)減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)系(xi)統。在(zai)二(er)級(ji)減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)系(xi)統，當旋擰調(diao)壓(ya)(ya)(ya)(ya)螺釘時，通過(guo)調(diao)壓(ya)(ya)(ya)(ya)彈(dan)簧、彈(dan)性薄膜(mo)裝及活(huo)門頂桿， 使(shi)減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)活(huo)門作不同(tong)程(cheng)度(du)的(de)開啟和關閉(bi)，以(yi)用來調(diao)節(jie)*減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)系(xi)統送入(ru)的(de)氧(yang)氣(qi)的(de)減(jian)(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)程(cheng)度(du)或停止供(gong)氣(qi)。
