Please refer to Figures 1 to 5. Figure 1 is a perspective view of a multi-wire
在圖1中,該多線彈簧閥體20包括一閥頭22及一多線彈簧10,其中該閥頭22係連接於該多線彈簧10;而該閥頭22包括複數個流通孔24用以使流體通過。In Figure 1, the multi-wire
在圖2及圖4中,該多線彈簧10包括一上環體11、一下環體15及複數個螺旋線圈。各該螺旋線圈具有二連接端,各該螺旋線圈的該二連接端中之一者係連接於該上環體11,而該二連接端中之另一者係連接於該下環體15。在本發明實施例中,該多線彈簧10係由含氟聚合物所構成,含氟聚合物例如可為聚四氟乙烯(PTFE),但不以此為限制。在本發明實施例中,該多線彈簧閥體20可係以一體成型的方式由含氟聚合物製成,含氟聚合物例如可為聚四氟乙烯(PTFE),但不以此為限制。In FIGS. 2 and 4, the
在圖3中,各該螺旋線圈具有複數個捲繞圈,且該螺旋線圈的該些捲繞圈與另一螺旋線圈的該些捲繞圈彼此交錯排列。在本發明實施例中,該些螺旋線圈包括一第一螺旋線圈12及一第二螺旋線圈14,該第一螺旋線圈12由連接於該上環體11的連接端往連接於該下環體15的另一連接端依序包括一第一捲繞圈12a及一第二捲繞圈12b。該第二螺旋線圈14由連接於該上環體11的連接端往連接於該下環體15的另一連接端依序包括一第三捲繞圈14a及一第四捲繞圈14b。其中,該第一捲繞圈12a、該第三捲繞圈14a、該第二捲繞圈12b及該第四捲繞圈14b由該上環體11往該下環體15依序排列。In FIG. 3, each of the spiral coils has a plurality of winding turns, and the winding turns of the spiral coil and the winding turns of another spiral coil are arranged alternately with each other. In the embodiment of the present invention, the helical coils include a first
如圖3所示,在該多線彈簧10未被壓縮前,各該捲繞圈的厚度為W1,而相鄰的該些捲繞圈之間的最短距離為W2,其中厚度W1係介於1.7~2.5 mm,而距離W2係介於2.5~3.5 mm。厚度W1與距離W2的比值(W1/W2)係介於0.5~1之間。藉此,該多線彈簧10可具有較佳的伸縮長度,以維持彈力需求又保有足夠的壓縮量,進而使包含該多線彈簧閥體20的逆止閥(圖未繪示)之閥開度及流量可維持最佳狀態。As shown in Fig. 3, before the
值得一提的是,如圖2及圖4所示,該多線彈簧10包括一上環體11、一下環體15及複數個螺旋線圈12、14。以該螺旋線圈12為例,該螺旋線圈12具有二連接端121、124分別連接於該上環體11及該下環體15。在本發明實施例中,該多線彈簧10的彈性係數(k)符合以下公式:
其中,d為各彈簧線徑;D為各彈簧直徑;Na為各彈簧的有效總圈數;G為各彈簧的材料係數。

舉例來說,若一單線彈簧的線徑(d)為2 mm、直徑(D)為20 mm、有效總圈數(Na)為6圈且材料係數(G)為5000,則該單線彈簧的彈力係數(k)依照公式可得出0.208。然而,若是依本發明實施例的多線彈簧10設計,該多線彈簧10中各螺旋線圈12、14的線徑(d)預設為2 mm、直徑(D)預設為20 mm、有效總圈數(Na)預設為3圈(二螺旋線圈12、14共為6圈)、且材料係數(G)為5000,則以各螺旋線圈12、14而言,各螺旋線圈12、14的彈力係數(k)為0.417;然若以多線彈簧10而言,多線彈簧10的彈力係數(k)為各螺旋線圈12、14的彈力係數(k)的總和,即多線彈簧10的彈力係數(k)約為0.834,為單一螺旋線圈12、14的2倍。因此,在同樣的壓縮高度下,雙線彈簧與單線彈簧的彈力係數(k)之間將相差3~4倍,且至少會有2倍以上的彈力係數(k)差異。除了上述彈力係數(k)的差異之外,本發明實施例所提供的多線彈簧10於上環體及下環體之間因連接有連接端彼此平衡的多個螺旋線圈,因此當多線彈簧10受控制伸縮時,相較於單線彈簧而言,本發明實施例所提供的多線彈簧10具有較佳的壓縮穩定性。For example, if the wire diameter (d) of a single-wire spring is 2 mm, the diameter (D) is 20 mm, the effective total number of turns (Na) is 6 and the material coefficient (G) is 5000, then the single-wire spring The coefficient of elasticity (k) can be obtained as 0.208 according to the formula.
