進(jìn)口高壓球閥(德國(guó)OLES奧萊斯閥門(mén))
【進(jìn)口高壓球閥】詳細(xì)說(shuō)明:
不銹鋼高壓球閥的球體是固定的,受壓后不產(chǎn)生移動(dòng)。固定球球閥都帶有浮動(dòng)閥座,受介質(zhì)壓力后,閥座產(chǎn)生移動(dòng),使密封圈緊壓在球體上,以保證密封。通常在與球體的上、下軸上裝有軸承,操作扭距小,適用于高壓和大口徑的閥門(mén)。為了減少氣動(dòng)球閥的操作扭矩和增加密封的可靠程度,出現(xiàn)了油封球閥,既在密封面間壓注特制的潤(rùn)滑油,以形成一層油膜,即增強(qiáng)了密封性,又減少了操作扭矩,更適用高壓大口徑的球閥。閥桿防飛結(jié)構(gòu):閥桿為下裝式,防止受壓飛出,同時(shí)可在火災(zāi)后,與閥體形成金屬接觸,確保閥桿密封。 不銹鋼高壓球閥的材質(zhì)是雙相不銹鋼(Duplex Stainless Steel,簡(jiǎn)稱(chēng)DSS)是指在其固溶組織中鐵素體相與奧氏體相約各占50%,一般量少雙相鋼的含量也需要 達(dá)到30%。在含 C 較低的情況下,Cr 含量在18%~28%,Ni 含量在3%~10%。
The ball body of stainless steel high-pressure ball valve is fixed and does not move after being pressed. Fixed ball valves are equipped with floating seats. After medium pressure, the seats move, so that the sealing ring is pressed on the ball to ensure sealing. Usually, bearings are installed on the upper and lower axles of the sphere, and the operation torque is small. It is suitable for high pressure and large caliber valves. In order to reduce the operating torque of pneumatic ball valves and increase the reliability of enclosed seals, oil-sealed ball valves have emerged, which not only inject special lubricating oil between the sealing surfaces to form a layer of oil film, which enhances the sealing performance, but also reduces the operating torque, and is more suitable for high-pressure and large-caliber ball valves. Stem anti-flying structure: the stem is downloaded to prevent pressure from flying out. At the same time, it can form metal contact with the valve body after fire to ensure the stem seal. The material of stainless steel high pressure ball valve is Duplex Stainless Steel (DSS), which means that the ferrite phase and austenite phase account for 50% respectively in its solid solution structure, and the content of less duplex steel also needs to reach 30%. When the content of C is low, the content of Cr is 18%~28%, and the content of Ni is 3%~10%.
【進(jìn)口高壓球閥】特點(diǎn):
1、不銹鋼高壓球閥產(chǎn)品的設(shè)計(jì)。
3、所有閥門(mén)流體阻力小。
4、開(kāi)閥速度快吸旋900即可完成開(kāi)關(guān)。
5、閥座材料采用聚醚醚酮PEEK、摩擦系數(shù)小密封可靠啟閉輕松。
6、球體在閥座之間的運(yùn)動(dòng)帶有擦拭作用,故可適用帶懸浮顆粒的介質(zhì)。
7、閥桿帶有上密封,并采用倒裝式結(jié)構(gòu),可防止在介質(zhì)壓力作用下閥桿沖擊。
8、根據(jù)用戶需要可設(shè)有防靜電,耐火和防止誤操作的鎖定機(jī)構(gòu)。
根據(jù)開(kāi)閉力的需要可浮動(dòng)球或固定球,固定球球閥其閥座地浮動(dòng)的,依靠介質(zhì)壓力在閥座上產(chǎn)生的活塞效應(yīng)實(shí)現(xiàn)密封,減輕了開(kāi)閉力。 標(biāo)準(zhǔn)(防火、防靜電)
【進(jìn)口高壓球閥】特性:
1、提高前輩的閥座:聚多年球閥制造經(jīng)驗(yàn)而設(shè)計(jì)的閥座,確保閥門(mén)密封,磨擦系數(shù)低,操縱力矩小、多種閥座材料、適應(yīng)范圍廣。
2、開(kāi)關(guān)無(wú)誤的手柄:采用扁頭閥桿,與手柄的連接不會(huì)錯(cuò)位,從而保證手柄指示的開(kāi)關(guān)狀態(tài)與閥*辭。
3、鎖緊裝置:為防止閥門(mén)開(kāi)關(guān)誤操縱,在閥門(mén)全開(kāi)、全關(guān)位置有鎖定孔,確保閥門(mén)處于準(zhǔn)確的位置。
4、閥桿防飛結(jié)構(gòu):閥桿為下裝式,防止受壓飛出,同時(shí)可在火災(zāi)后,與閥體形成金屬接觸,確保閥桿密封。
