Fyuluta yopanikizavalavu ya mpirandi gawo la mapaipi lomwe limaphatikiza ntchito zosefera ndi zowongolera kuyenda kwa madzi. Valavu iyi imayika chophimba chosefera munjira yoyendera ya valavu yachikhalidwe ya mpira. Pamene cholumikizira (madzi, mafuta kapena madzi ena) chikudutsa, choyamba chimaletsa dothi, dzimbiri ndi zinyalala kudzera mu chophimba chosefera. Kenako, pozungulira pakati pa mpira wa valavu ya mpira 90°, payipiyo imatha kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu. Chifukwa chake, pamene ikukwaniritsa zowongolera kuyenda kwa madzi, cholumikiziracho chimasefedwa ndikuyeretsedwa.

Njira yolumikizira "compression" imagwiritsa ntchito zida zapadera kuti zikanikizire bwino kulumikizana pakati pa chitoliro ndi valavu, ndikupanga chisindikizo chodalirika komanso cholumikizira chamakina, kuonetsetsa kuti kutseka kukugwira ntchito bwino komanso kukhazikika kwa kapangidwe ka mapaipi.

Ponena za ubwino wogwiritsa ntchito, valavu ya mpira wa fyuluta yokakamiza ili ndi zabwino zambiri: imagwiritsa ntchito kapangidwe kogwirizana, kuphatikiza ntchito zoyezera kusefa ndi kuyendetsa madzi kukhala chimodzi, kuchepetsa zolumikizira mapaipi, ndikusunga malo ndi ndalama zoyikira; Imatha kusefa bwino zinyalala, kuteteza mavavu, zida, zida zoyambira, ndi zina zotero kuti zisatsekeke ndi kuwonongeka, ndikuwonjezera nthawi yawo yogwirira ntchito. Vavu ya mpira ndi yosavuta kugwiritsa ntchito komanso yopulumutsa ndalama. Kulumikizana ndi kukhazikitsa kumafulumira, ndipo ntchito yokonza pambuyo pake monga kuyeretsa chophimba cha fyuluta nayonso ndi yosavuta kwambiri. Ili ndi magwiridwe antchito abwino kwambiri otsekera komanso okana kupanikizika nthawi imodzi, imatha kusunga kutayikira pansi pa kuthamanga kwambiri, ndipo ndi yoyenera kugwiritsa ntchito zinthu zosiyanasiyana zamadzimadzi.

Valavu ya mpira wa fyuluta yokakamiza, yokhala ndi ubwino wake wophatikizana wa "kusefa + kuwongolera", kugwiritsa ntchito bwino ndi kukonza, komanso magwiridwe antchito odalirika, yakhala gawo lofunikira lomwe ndi lothandiza komanso lotsika mtengo m'makina a mapaipi, ndipo lili ndi malo ofunikira m'magawo osiyanasiyana ogwiritsira ntchito anthu wamba komanso mafakitale.

Jinbin Valves yakhala ikupanga ma valve kwa zaka 20. Ndi luso laukadaulo komanso chitsimikizo cha khalidwe, timapanga ma valve apamwamba kwambiri monga ma valve a gulugufe a mafakitale, ma valve a zipata, valavu ya mpira wolumikizidwa, valavu ya blind plate, valavu ya penstock yokhazikika pakhoma, zipata za beam, ma valve a mpweya, ma valve a hollow Jet, ndi zina zotero. Ngati muli ndi zosowa zina zokhudzana ndi izi, chonde titumizireni uthenga pansipa ndipo mudzalandira yankho mkati mwa maola 24!
