Valavu Yowonjezera ya DBB Seal Dual Seal

Thupi la valavu la Twin Seal DBB Plug Valve Orbit Dual Expanding General Valve limaphatikizapo thupi la valavu, pulagi ya valavu, diski ya valavu (yomwe imayikidwa mu mphete yayikulu yotsekera), chivundikiro chakumapeto, chassis, kulongedza ndi zinthu zina zazikulu. Pakati pa valavu ndi diski ndiye pakati pa gawo la thupi la valavu. Pulagi ya valavu imakhazikika m'thupi la valavu ndi ma trunnion apamwamba ndi otsika, kutsegula kwa njira yoyendera kuli pakati, ndipo mbali ziwirizo ndi malo ooneka ngati wedge. Mphero ya nkhope ya wedge ili ndi njanji zowongolera za dovetail zomwe zimalumikizidwa ku ma diski awiri mbali zonse ziwiri. Disiki ndiye chinthu chachikulu chotsekera ndipo ili ndi pamwamba pa cylindrical. Kulondola kwa chisindikizo cholimba cha Class B kumatha kuchitika. Pansi pa cylindrical imaphwanyidwa ndi bwalo la groove, ndipo mphete yayikulu yotsekera imayikidwa kosatha ndi rabara ya fluorine kapena nitrile, ndi zina zotero pomanga ndi vulcanization, zomwe zimagwira ntchito yotseka yolimba ndi kutseka yofewa pamene valavu yatsekedwa.
Vavu ya DBB Plug (yomwe ndi valavu ya block ndi bleed plug) imatchedwanso GENERAL VALVE, Twin Seal plug valavu. Izi zimawonongeka nthawi zonse pogwiritsa ntchito mipando iwiri yokhazikika pa pulagi yopapatiza yokhala ndi michira ya dovetail, yomwe imabwerera m'mbuyo kuchokera pamwamba pa mipando isanayambe kuzungulira. Izi zimapangitsa kuti chisindikizo chawiri chikhale cholimba ngati thovu popanda kusweka kwa chisindikizo.
Chida chowongolera mpweya chimakhala ndi zizindikiro, gudumu lamanja, ma spindle bushings, ma ball pini, ma brackets ndi zinthu zina, zomwe zimakhazikika pa chivundikiro chakumapeto ndipo zimalumikizidwa ndi ndodo ya spool pogwiritsa ntchito ma connection pini. Gawo la chida chowongolera mpweya ndiye choyambitsa ntchito. Tsekani valavu kuchokera pamalo otseguka, tembenuzani gudumu lamanja mozungulira wotchi, valavu imazungulira 90° choyamba, ndikuyendetsa valavu kuti izungulire kupita kumalo oyendera madzi a valavu. Kenako valavu imatsika pansi molunjika, ikuyendetsa valavu kuti ikule mozungulira ndikuyandikira khoma lamkati la valavu mpaka chisindikizo chofewa chitakanikizidwa mu groove, kotero kuti pamwamba pa valavu disc ikhudze khoma lamkati la valavu.
Tsegulani valavu kuchokera pamalo otsekedwa, tembenuzani gudumu lamanja mozungulira wotchi, valavu yapakati imayenda molunjika mmwamba, kenako imazungulira 90° mutafika pamalo enaake, kotero kuti valavuyo ili mu mkhalidwe woyendetsa.
