10、又由于所述第(di)一連接頭或第(di)二連接頭上設置有與所述施(shi)力(li)(li)部(bu)配(pei)合的法(fa)(fa)蘭(lan)部(bu),所述施(shi)力(li)(li)部(bu)和(he)法(fa)(fa)蘭(lan)部(bu)之(zhi)間擠(ji)(ji)壓有提供彈(dan)性(xing)力(li)(li)的彈(dan)性(xing)件。利用彈(dan)性(xing)件可以給迫使給法(fa)(fa)蘭(lan)部(bu)提供彈(dan)性(xing)力(li)(li),這樣可以避免(mian)第(di)一防旋配(pei)合面(mian)和(he)第(di)二防旋配(pei)合面(mian)之(zhi)間的擠(ji)(ji)壓力(li)(li)過大而導(dao)致后續擰松困(kun)難。
11、又(you)由(you)于所述(shu)第(di)(di)一(yi)(yi)防(fang)(fang)旋(xuan)(xuan)(xuan)配(pei)(pei)(pei)合面(mian)(mian)(mian)為(wei)設置于所述(shu)第(di)(di)一(yi)(yi)連接(jie)頭(tou)端部的(de)端面(mian)(mian)(mian),所述(shu)第(di)(di)二防(fang)(fang)旋(xuan)(xuan)(xuan)配(pei)(pei)(pei)合面(mian)(mian)(mian)和安裝(zhuang)(zhuang)軸(zhou)段之(zhi)間(jian)的(de)銜接(jie)處設置有密(mi)封(feng)(feng)圈(quan)安裝(zhuang)(zhuang)槽,所述(shu)密(mi)封(feng)(feng)件為(wei)密(mi)封(feng)(feng)圈(quan),所述(shu)第(di)(di)一(yi)(yi)防(fang)(fang)旋(xuan)(xuan)(xuan)配(pei)(pei)(pei)合面(mian)(mian)(mian)與所述(shu)密(mi)封(feng)(feng)圈(quan)接(jie)觸的(de)區域設置成光滑(hua)平面(mian)(mian)(mian),這(zhe)樣(yang)當旋(xuan)(xuan)(xuan)緊套旋(xuan)(xuan)(xuan)轉時第(di)(di)一(yi)(yi)防(fang)(fang)旋(xuan)(xuan)(xuan)配(pei)(pei)(pei)合面(mian)(mian)(mian)和第(di)(di)二防(fang)(fang)旋(xuan)(xuan)(xuan)配(pei)(pei)(pei)合面(mian)(mian)(mian)相(xiang)互擠(ji)(ji)壓時也會(hui)擠(ji)(ji)壓所述(shu)密(mi)封(feng)(feng)圈(quan),從(cong)而實現(xian)安裝(zhuang)(zhuang)軸(zhou)段和安裝(zhuang)(zhuang)套孔之(zhi)間(jian)的(de)相(xiang)互密(mi)封(feng)(feng),保證氣密(mi)性。
12、又由于當所(suo)(suo)述(shu)彈(dan)性件為彈(dan)性密封環(huan)時,所(suo)(suo)述(shu)施力部上設置有(you)擠(ji)(ji)壓(ya)(ya)所(suo)(suo)述(shu)彈(dan)性密封環(huan)的傾(qing)斜面,所(suo)(suo)述(shu)傾(qing)斜面擠(ji)(ji)壓(ya)(ya)所(suo)(suo)述(shu)彈(dan)性密封環(huan)產(chan)生一個指向(xiang)軸(zhou)(zhou)心(xin)線(xian)的分力,這樣(yang)利用該(gai)施力部上的傾(qing)斜面可以擠(ji)(ji)壓(ya)(ya)所(suo)(suo)述(shu)彈(dan)性密封環(huan),這樣(yang)不但(dan)提供(gong)了軸(zhou)(zhou)向(xiang)的彈(dan)性力而且還能進行(xing)二次密封,進一步提高氣(qi)密性。
