二、固(gu)定式(shi)球(qiu)(qiu)閥(fa)(fa)結構特點固(gu)定式(shi)球(qiu)(qiu)閥(fa)(fa)同樣(yang)(yang)有進出口兩個閥(fa)(fa)座密(mi)封(feng)圈(quan)。中間的(de)球(qiu)(qiu)芯通過上閥(fa)(fa)桿(gan)和(he)下閥(fa)(fa)桿(gan)，與閥(fa)(fa)體固(gu)定在一起(qi)。只能通過閥(fa)(fa)桿(gan)的(de)轉動(dong)，帶動(dong)球(qiu)(qiu)芯的(de)開關動(dong)作(zuo)。其無(wu)法像浮動(dong)球(qiu)(qiu)閥(fa)(fa)那樣(yang)(yang)，向出口方向移動(dong)，因為上下閥(fa)(fa)桿(gan)限(xian)制了(le)球(qiu)(qiu)芯的(de)移動(dong)。所以稱為固(gu)定式(shi)球(qiu)(qiu)閥(fa)(fa)。

進出口的閥座(zuo)通過(guo)彈(dan)簧(huang)預緊力給了(le)(le)球(qiu)芯與閥座(zuo)間的初始密(mi)封壓力。介質的壓力推動(dong)(dong)閥座(zuo)密(mi)封圈壓緊球(qiu)芯。增加了(le)(le)閥座(zuo)的密(mi)封性能(neng)。當閥座(zuo)密(mi)封磨損時，閥座(zuo)在彈(dan)簧(huang)的作用下，自(zi)動(dong)(dong)補(bu)償(chang)磨損部分，依然保(bao)持(chi)良(liang)好(hao)的密(mi)封性。

由于閥(fa)(fa)座截面是一個(ge)圓環。介質壓(ya)(ya)力(li)作用面積要小(xiao)于球芯截面積，所以閥(fa)(fa)座受到(dao)壓(ya)(ya)力(li)要比(bi)浮動球閥(fa)(fa)小(xiao)。即(ji)減小(xiao)了(le)球閥(fa)(fa)的(de)(de)(de)閥(fa)(fa)桿扭矩。所以在高壓(ya)(ya)大口(kou)徑球閥(fa)(fa)中，都采用固定(ding)式球閥(fa)(fa)。廣東(dong)高壓(ya)(ya)球閥(fa)(fa)定(ding)制浙江萬聯閥(fa)(fa)業(ye)生產的(de)(de)(de)美標不銹鋼(gang)法蘭球閥(fa)(fa),用于管道(dao)泵的(de)(de)(de)組件(jian),是制造泵業(ye)公(gong)司的(de)(de)(de)好伙伴.

偏(pian)心(xin)(xin)半球閥(fa)(fa)重(zhong)點在(zai)(zai)于偏(pian)心(xin)(xin)。即閥(fa)(fa)軸和半球體的(de)(de)中心(xin)(xin)線(xian)有(you)一個(ge)尺寸(cun)偏(pian)量。這(zhe)個(ge)偏(pian)心(xin)(xin)使(shi)球芯(xin)與(yu)閥(fa)(fa)座(zuo)之(zhi)間(jian)的(de)(de)接觸存在(zai)(zai)很短，只在(zai)(zai)關閉和打開閥(fa)(fa)門的(de)(de)瞬間(jian)存在(zai)(zai)接觸。減(jian)少了閥(fa)(fa)芯(xin)與(yu)閥(fa)(fa)座(zuo)的(de)(de)磨(mo)損(sun)。延長了閥(fa)(fa)門使(shi)用壽命.

V型(xing)(xing)球閥(fa)的閥(fa)芯也是采用(yong)半(ban)球結構，重點在于(yu)閥(fa)芯上(shang)開有V型(xing)(xing)口，通(tong)過(guo)V型(xing)(xing)口可以(yi)(yi)控(kong)制更小的流量，同時(shi)其流通(tong)能力比一般調(diao)(diao)節閥(fa)要大。所以(yi)(yi)其可調(diao)(diao)比遠遠超過(guo)普通(tong)調(diao)(diao)節閥(fa)。但是V型(xing)(xing)球閥(fa)球芯密封面(mian)與閥(fa)座始終(zhong)處于(yu)密切接觸(chu)狀態。閥(fa)軸與半(ban)球體中心線處于(yu)流道中心線，沒有偏心結構。
