Ku...wafer valve yo kambela tipuleti timbirhinakambe i muxaka wa check valve leyingana rotary actuation, kambe i double disc naswona yi pfala ehansi ka action ya spring. Disiki yi susumetiwa yi pfuleka hi mati yale hansi kuya e henhla, valve yina xivumbeko xo olova, clamp yi vekiwa exikarhi ka ti flanges timbirhi, naswona vukulu lebyintsongo na ntiko wo vevuka swile hansi.
Ku...wafer valve yo kambela tipuleti timbirhiyi na ti disc timbirhi ta xivumbeko xa D leti nga na spring leti vekiweke eka ribbed shaft ku tsemakanya bore ya valve. Xivumbeko lexi xi pfuxeta mpfhuka lowu ntsindza wa nkoka-misava wa disiki wu fambaka ha wona. Ku akiwa loku kutlhela kuhunguta ntiko wa disc hi 50% loko ku pimanyisiwa na single-disc swing-on check valve ya sayizi leyi fanaka. Hikwalaho ka ndzhwalo wa spring, valve yi angula hiku hatlisa swinene eka backflow.
Ku akiwa ka wafer dual plate check valve ya double-lobe yo vevuka swi endla leswaku ku pfariwa ka switulu na ku tirha swi tirha kahle.
Xiendlo xa ximun’wana xa voko ro leha xa phaphatani leri nga ni swiphemu swimbirhivalve yo kambelaswi pfumelela disiki ku pfuleka no pfala handle ko rhurhumela xitulu, naswona xihlovo xi tirha hi ku tiyimela ku pfala disiki (DN150 na le henhla).
Sleeve yo seketela leyi hingeke ya phaphatani leri nga ni swiphepherhele swimbirhivalve yo kambelaswihunguta friction naswona swihunguta hammer ya mati loko yi herisiwa hiku tirhisa disc leyi hambaneke (bore leyikulu).
Loko swi pimanisiwa ni leswi tolovelekekeswing check valves,wafer valve yo kambela tipuleti timbirhihi ntolovelo ku aka ku tiyile, ku vevuka, kutsongo, ku tirha kahle naswona a ku durhi ngopfu. Valve leyi yi fikelela standard ya API 594, eka ti diameters totala, vukulu bya face-to-face bya valve leyi i ntsena 1/4 wa valve ya ntolovelo, naswona ntiko i 15%~20% wa valve ya ntolovelo, hikokwalaho yitlhela yi chipa kutlula swing check valve. Switlhela swi olova ku veka exikarhi ka ti gaskets leti tolovelekeke na ti pipe flanges. Hikuva ya olova ku yi khoma naswona yi lava ntsena sete yin’we ya ti flange connection bolts, yitlhela yi hlayisa swiphemu hi nkarhi wa ku vekiwa, leswi hlayisaka mali yo veka xikan’we naku hlayisa siku na siku.
Valve yo kambela maphaphatani ya double-flap yitlhela yiva na swihlawulekisi swo hlawuleka swo aka leswi endlaka leswaku valve leyi yiva valve yo kambela ya matirhelo yale henhla leyinga khumbekiki. Swihlawulekisi leswi swikatsa ku pfuleka lokunga basangiki, ku akiwa ka spring loku tiyimeleke eka ti bore valve totala, na tisisiteme ta nseketelo wa disc leti tiyimeleke. Swin’wana swa swilo leswi a swi kumeki eka ti- check valve. Valve ya wafer dual plate check yinga tlhela yi endliwa hi ti lugs, ti double flanges xikan’we na miri lowu andlariweke.
Xo sungula, endlelo ro pfula ni ro pfala
Ku akiwa ka ti disk timbirhi ku na ti disc timbirhi leti nga na spring-loaded (semi-discs) leti hayekiweke eka pini leyi nga na hinged leyi yimisiweke exikarhi. Loko mati ma sungula ku khuluka, disiki yi pfuleka hi matimba lama humelelaka (F) lama tirhaka exikarhi ka ndhawu leyi pfalaka. Matimba ya nseketelo wa xihlovo ya counteractive (FS) ya tirhisiwa eka ndzhawu yale handle ka xikarhi ka xikandza xa disc, leswi endlaka leswaku rimitsu ra disc ri pfuleka rosungula. Leswi swi papalata ku hlangana eka ndzhawu yo pfalela loku humelelaka loko disc yi pfuriwa eka ti valve ta khale leti tolovelekeke, leswi herisaka ku onhaka na ku handzuka eka swiphemu.
Loko mpimo wa ku khuluka wu hunguta rivilo, torsion spring yi endla hi yoxe, leswi endlaka leswaku disc yi pfala naswona yi tshinela ekusuhi ni xitulu xa miri, leswi hungutaka mpfhuka wo famba ni nkarhi wo pfala. Loko mati lawa ya khuluka ya tlhelela endzhaku, disc hakatsongo-tsongo yi tshinela ekusuhi ni xitulu xa miri, naswona nhlamulo ya matimba ya valve yi hatlisisiwa swinene, leswi hungutaka vuyelo bya hammer ya mati ni ku fikelela matirhelo lama nga riki na ku khumbeka.
Loko ku pfala, xiendlo xa spring force action point xi endla leswaku le henhla ka disc ku pfala ku sungula, leswi sivela ku luma na ku hlangana eka rimitsu ra disc, leswaku valve yi kota ku hlayisa vutshembeki bya seal kuringana nkarhi woleha.
2. Xivumbeko xa ximun’wana lexi tiyimeleke
Ku akiwa ka spring (DN150 kuya e henhla) swipfumelela ku tirhisiwa ka torque leyikulu eka disc yin’wana na yin’wana naswona disc yi pfala hiku tiyimela loko ku khuluka ka ti indasitiri ku cinca. Swikambelo swikombe leswaku mbuyelo lowu wu endle leswaku kuva na ku tlakuka ka 25% eka vutomi bya valve xikan’we naku hunguteka ka 50% eka hammer ya mati.
Xiphemu xin’wana na xin’wana xa double disc xina swihlovo swa xona leswi nyikaka matimba yo pfala yo tiyimela naswona swi endliwa eka angular offset leyintsongo swinene ya 140° (fig. 3) ematshan’wini ya 350° ya spring leyi tolovelekeke leyingana ti brackets timbirhi.
3. Xivumbeko xa ku yimisiwa ka disiki lexi tiyimeleke
Xivumbeko xa hinge lexi tiyimeleke xi hunguta friction hi 66%, leswi antswisaka swinene ku cinca ka valve. Sleeve ya nseketelo yi nghenisiwa kusuka eka hinge yale handle leswaku hinge yale henhla yita seketeriwa hiku tiyimela hi sleeve yale hansi hinkarhi wa ntirho wa valve. Leswi swi pfumelela ti disc leti hatimbirhi ku angula hi ku hatlisa no pfala hi nkarhi wun’we, ku fikelela matirhelo ya kahle swinene ya dynamic.
Xa vumune, ndlela yo hlanganisa na phayiphi
Tivalvu to kambela tipuleti timbirhi ta wafernaswona tiphayiphi tinga hlanganisiwa hi ti clamps, ti lugs, ti flanges, na ti clamps.
