Pneumatic vacuum ball valve is a product specially designed and carefully manufactured on the basis of introducing advanced international technology. With electric valve positioner, the operation can be controlled by inputting 4-20 mADC signal and 0.5-0.7 Mpa gas source to realize the adjustment of pressure, flow rate, temperature, liquid level and other parameters. It is driven by compressed air, and the valve stem drives the spool to rotate 90 degrees in the valve body, so it can realize the action of full opening and full closing. The product can be divided into metal seal and soft seal according to its sealing performance. Series vacuum (pressure) ball valves are suitable for connecting or cutting off the medium flow in the vacuum system. The valve is a through ball valve, which is sealed by spherical surface, so it can be used not only in vacuum, but also in low pressure, and can be installed at any position. Pneumatic vacuum ball valves change the direction of the air passage through the solenoid directional valve, and control the actuating cylinder to drive the ball valve, so as to connect or cut off the medium flow in the vacuum (pressure) system road. The suitable working medium is acid and alkaline gas or liquid, which is used in vacuum, dairy products, wine industry, bioengineering, food, pharmaceutical, beverage, cosmetics and chemical industry. Feedback signal device and electric valve positioner are optional.
【進(jìn)口氣動(dòng)真空球閥】工作原理與結(jié)構(gòu)：
氣動(dòng)真空球閥由氣動(dòng)活塞式執(zhí)行機(jī)構(gòu)與O型球閥組合構(gòu)成。氣動(dòng)執(zhí)行機(jī)構(gòu)相同規(guī)格有雙作用式、單作用式(彈簧復(fù)位)；標(biāo)準(zhǔn)旋轉(zhuǎn)軸角度可調(diào)節(jié)-5～+50范圍；所有滑動(dòng)部件采用塑料軸承襯套、導(dǎo)向，保持小摩擦力，并有效地抵抗磨損；外殼表面陽(yáng)極化電鍍，防腐蝕保護(hù)；旋轉(zhuǎn)軸鍍硬質(zhì)鎳磷合金；螺絲、 螺母為不銹鋼；單作用式彈簧預(yù)裝在彈簧座內(nèi)，很容易裝配或增補(bǔ)彈簧數(shù)量；連接、安裝接口標(biāo)準(zhǔn)化模塊設(shè)計(jì)，方便配裝球閥、信號(hào)盒及控制附件；可選擇旋轉(zhuǎn)方向順時(shí)針旋轉(zhuǎn)或逆時(shí)針旋轉(zhuǎn)；兩端調(diào)節(jié)螺絲可調(diào)節(jié)小于標(biāo)定角度調(diào)整。特殊的腐蝕環(huán)境可采用不銹鋼外殼。浮動(dòng)球閥采用特殊設(shè)計(jì)的雙斜面彈性密封圈，有效的降低了球體與密封圈之間的摩擦力，減少了操作力矩。當(dāng)介質(zhì)壓力較小時(shí)，密封圈與球體接角面積較小，故有較大的密封比壓，確?？煽棵芊?。當(dāng)介質(zhì)力較大時(shí)，密封圈與球體面積也相應(yīng)增大。故密封圈能承受較大的介質(zhì)推力而不會(huì)損壞，確?？煽棵芊?。當(dāng)介質(zhì)的沖刷力較大時(shí)，特別設(shè)計(jì)的閥座防沖刷結(jié)構(gòu)能有效的防止介質(zhì)的沖刷，確保密封圈的使用壽命。對(duì)于低壓，超低壓或真空工況用球閥，因介質(zhì)本身的壓力不能確保閥座可靠密封，而預(yù)緊力*使用后又會(huì)衰減，特別設(shè)計(jì)的彈簧加載密封結(jié)構(gòu)，能確保閥門(mén)*可靠使用。
