摘要：
A pressure regulating valve for a cupping negative pressure apparatus is provided with an upper pressure regulating valve screw cap and a lower pressure regulating valve body having a metal nut structure inside, and the metal nut structure is provided with a plurality of nut pressure relief holes. The pressure regulating valve screw cap can be tightened to block circulation of the nut pressure relief holes. A muffler cover assembly seat is disposed on an outermost side of a metal nut structure assembly seat for assembling a muffler cover, small holes for circulating air are disposed between the muffler cover and the metal nut structure assembly seat. The pressure regulating valve body has negative pressure communication holes for sucking and discharging air and the negative pressure communication holes are communicated or plugged by quick-plug screw caps. A filter cotton is disposed in the pressure regulating valve body.本創作用於拔罐負壓儀的調壓閥，調壓閥上半部為旋蓋，旋蓋內側金屬材質螺旋結構，調壓閥下半部為閥體，閥體周圍設有複數個圓圈柱體，閥體內部有一金屬螺母結構，螺母金屬結構上有數個小洞，用於調節力道流通空氣達到調整負壓力道的效果，使用者在使用時可將調壓閥旋蓋與閥體拴緊，止擋螺母金屬結構上小洞流通，讓閥體內部為氣密狀態負壓力道最大。當真空壓力過大，使用者可旋轉調壓旋蓋使閥體內側螺母結構小洞與外部流通，使外部空氣流通進閥體，降低真空壓力，而達到調節負壓力道的效果。閥體最外側設有一消音蓋組裝座，圍繞整個閥體內部結構，其消音蓋組合座可以消音蓋組合，使調壓閥與旋蓋之間流通空氣的小孔於消音蓋與消音蓋組合座之間的空間內，使小孔流通外部空氣時在一空間內緩衝降低氣音流通的音量，讓使用者能夠不受調壓閥洩壓噪音影響，專心使用拔罐負壓儀。
