复合式减压阀制造技术

一种复合式减压阀，该减压阀主要是于阀本体内以一球阀开关组、一阀门控制组及一减压缓冲组等组件所构成，且于阀本体的外侧分别设置有第一压力表及第二压力表，其特征在于， 阀本体，以铸铜模制成一内部回绕具有一次侧阀道及二次侧阀道的管体，于二次侧阀道旁端的选定处则区隔设有一控压室，令控压室设有一导孔通往二次侧阀道，且控压室的侧壁开设有一通孔； 球阀开关组，借助一球阀受把手的拨转，而供减压阀作为选定控制一次侧入水流的流向控制装置； 阀门控制组，组设于一次侧阀道内控制通过阀门的水流量大小，其阀座前端的塞片以一塞片压杆予以固定； 减压缓冲组，将其减压膜片封盖组设于控压室的一侧，令减压膜片的顶杆自通孔而导伸至控压室外，并弹性顶抵于阀门控制组的塞片压杆； 利用上述构件组成，可令二次侧阀道的瞬变水压通过导孔通往控压室，并直接受减压膜片予以反应吸收，使阀门控制组的阀座带动塞片于顶杆受减压膜片连动退缩时，得以适当的匀速改变阀门的大小，从而令一次侧阀道与二次侧阀道内的水压迅速地获得平衡调节，使二次侧于瞬变水压时不会有水锤噪音的产生。（*该技术在2012年保护过期，可自由使用*）

Composite pressure reducing valve

A composite type valve, the valve is mainly composed of the valve body with a valve in the switch group, a control group and a decompression valve buffer group and other components, and on the outside of the valve body are respectively provided with a first pressure gauge and two gauge, which is characterized in that the valve body, to cast copper mold into a pipe body of internal winding has a primary side valve and two side valve, selected in two along the side of the valve end segment is provided with a pressure control chamber, the pressure control chamber is provided with a guide hole to the two side of the valve, and the control pressure chamber is arranged on the side wall a through hole; the valve switch group, with the help of a ball valve by rotating handle, and a control valve as the selected side into the water flow control device; the valve control group, set up a side valve in the control of water flow through the size of the valve, plug the front end of the seat to A plug rod to be fixed; decompression buffer group, the control group is arranged on the side of the diaphragm vacuum sealing pressure chamber, the vacuum diaphragm rod through hole and extends to the outside pressure control, and elastic butted with the plug valve control group pressure bar; composed by the members, can make two times the side valve transient pressure through the guide hole to the pressure control chamber, and directly affected by the reaction to the diaphragm vacuum absorption, valve control group drives the plug piece on the ejector seat by vacuum diaphragm linking back when properly uniform change valve size, so that one side of the valve and the two valve side in the water quickly to get the balance regulation, two side does not produce water hammer noise in transient pressure.

【技术实现步骤摘要】

本技术涉及一种复合式减压阀，尤指一种于二次侧产生瞬变水压时，将水波脉冲予以缓冲吸收，同时亦可匀速调整阀门的开启程度，令二次侧可获一稳定水压的复合式减压阀的结构设计。而现今年使用的减压阀组，是以个别的球阀、减压阀及数个闸阀彼此间以管路采用串接或并联的方式所组成，其不仅有施工组装缓慢、体积占用空间庞大、造价昂贵等缺陷，又因其各个部件的品质良莠不齐，于维修上甚为麻烦。于是，乃有如台湾申请案号第87207744号的“减压阀组改良”新型专利设计，将上述的缺陷予以改良。但是，该案的改良设计并不尽完善，因其于减压阀内的减压膜片与阀门塞片之间，借助一导杆予以连结作动，故当二次侧有水压脉冲瞬间震动时，该减压膜片即会同步连动阀门塞片，将阀门的信道予以强制瞬间急开或急关，如此，水压脉冲无法有效地减缓消除而产生水锤效应，使管路配件及压力表的寿命大受影响。本技术的次要目的，在于提供一种复合式减压阀的结构设计，主要是于阀本体内以一球阀开关组、一阀门控制组及一减压缓冲组等组件所构成，令球阀开关组及阀门控制组均结设于阀本体一次侧的阀道内，而减压缓冲组则结设封盖于阀本体二次侧阀道内的一控压室旁侧，且令减压缓冲组本文档来自技高网...
