Wopanga ndi kusankha mlangizi wa mavavu a mapaipi mu control fluid fluid
Ndife akatswiri opanga ma valve omwe ali ndi zaka zambiri zopanga komanso zotumiza kunja. Timadziwa bwino kapangidwe kake ndi mfundo za ma valve osiyanasiyana ndipo titha kukuthandizani kusankha mtundu woyenera kwambiri wa valavu molingana ndi media media komanso malo osiyanasiyana. Tikuthandizani kuti muwononge ndalama zocheperako mukamakwaniritsa zofunikira zogwiritsira ntchito ndikuwonetsetsa moyo wautumiki.
Zomwe zimagwira ntchito za valve
Mavavu athu chimagwiritsidwa ntchito mafuta, makampani mankhwala, gasi zachilengedwe, papermaking, zimbudzi mankhwala, mphamvu nyukiliya, etc. Cholinga pa zinthu zosiyanasiyana nkhanza ntchito, monga kutentha, kuthamanga, acidity wamphamvu, alkalinity wamphamvu, mikangano mkulu, etc. Ma valve athu ndi osinthika kwambiri. Ngati mukufuna kuwongolera kuthamanga, kuwongolera kutentha, kuwongolera pH, ndi zina zambiri zamapaipi, mainjiniya athu adzakupatsaninso upangiri waukadaulo ndikusankha.
Zithunzi za NSW
NSW imatsatira mosamalitsa dongosolo la ISO9001 lowongolera. Timayamba kuchokera kuzinthu zoyamba za thupi la valve, chivundikiro cha valve, ziwalo zamkati ndi zomangira, kenaka timakonza, kusonkhanitsa, kuyesa, kujambula, ndipo pamapeto pake phukusi ndi sitima. Timayesa mosamala valavu iliyonse kuti titsimikize kuti valve ya Zero yatuluka komanso yotetezeka kugwiritsa ntchito, yapamwamba, yapamwamba komanso moyo wautali.
Zogulitsa za valve zomwe zimagwiritsidwa ntchito kwambiri pamapaipi amakampani
Mavavu m'mapaipi a mafakitale ndi zida zamapaipi zomwe zimagwiritsidwa ntchito potsegula ndi kutseka mapaipi, kuwongolera koyenda, kusintha ndi kuwongolera magawo (kutentha, kuthamanga ndi kutuluka) kwa sing'anga yotumizidwa. Vavu ndi gawo lowongolera mumayendedwe amadzimadzi pamapaipi amakampani. Lili ndi ntchito zodula, kudula mwadzidzidzi, kutsekereza, kuwongolera, kupatutsa, kuletsa kuthamangitsidwa, kukhazikika kwamphamvu, kupatutsa kapena kusefukira kwamphamvu kwamphamvu ndi ntchito zina zowongolera madzimadzi. Angagwiritsidwe ntchito kulamulira otaya mitundu yosiyanasiyana ya madzimadzi monga mpweya, madzi, nthunzi, zosiyanasiyana zikuwononga TV, matope, mafuta, madzi zitsulo ndi wailesi radioactive.
Mitundu ya ma valve a mapaipi a mafakitale a NSW
Zomwe zimagwirira ntchito m'mapaipi a mafakitale ndizovuta, kotero NSW imapanga, imapanga, ndi kupanga mitundu yosiyanasiyana ya ma valve kuti agwiritsidwe ntchito mosiyanasiyana kuti akwaniritse ntchito ndi zofunikira zomwe ogwiritsa ntchito amafunikira panthawi yogwiritsira ntchito.
Emergency Shut Down Valve ndi valavu yopangidwa mwapadera, yomwe imagwiritsidwa ntchito makamaka mu mapaipi a gasi kapena amadzimadzi, omwe amatha kudula mwachangu madzi mu payipi mwadzidzidzi kuti atsimikizire chitetezo cha ogwira ntchito ndi zida. Vavu iyi nthawi zambiri imayikidwa pazida zamagetsi zamagetsi, zotengera matanki, akasinja osungira kapena mapaipi, ndipo imatha kutsekedwa mwachangu pamanja kapena pakachitika ngozi. Ntchito yayikulu ya Valve ya Emergency Shut-Down Valve ndikutseka kapena kutseguka mwachangu pakagwa ngozi kuti mupewe ngozi kapena kuchepetsa kuchuluka kwa ngozi.
Mavavu a Mpira
Pakatikati pa valve ndi mpira wozungulira wokhala ndi dzenje. Chovalacho chimasuntha tsinde la valavu kotero kuti kutsegula kwa mpira kutseguke bwino pamene ikuyang'ana pamphepete mwa payipi, ndipo imatsekedwa kwathunthu ikatembenuzidwira 90 °. Valve ya mpira imakhala ndi kusintha kwina ndipo imatha kutseka mwamphamvu.
Mavavu a Butterfly
Pakatikati pa valve ndi mbale yozungulira yozungulira yomwe imatha kuzungulira molunjika kumtunda wa payipi. Pamene ndege ya mbale ya valve ikugwirizana ndi olamulira a chitoliro, imatsegulidwa kwathunthu; pamene ndege ya gulugufe valavu mbale ndi perpendicular kwa olamulira chitoliro, izo kwathunthu chatsekedwa. Kutalika kwa valavu ya butterfly ndi yaying'ono ndipo kukana kwamadzi kumakhala kochepa.
Pulagi Valve
Mawonekedwe a pulagi ya valve akhoza kukhala cylindrical kapena conical. M'mapulagi a cylindrical valve, ngalandezo zimakhala zamakona anayi; m'mapulagi a valve opangidwa ndi tapered, njirazo ndi trapezoidal. Mwa zina, valavu ya pulagi ya DBB ndi chinthu chopikisana kwambiri ndi kampani yathu.
Chipata cha Chipata
Imagawidwa kukhala tsinde lotseguka ndi tsinde lobisika, chipata chimodzi ndi chipata chachiŵiri, chipata cha mphero ndi chipata chofanana, ndi zina zotero, komanso palinso valve yamtundu wa mpeni. Kukula kwa valavu ya pachipata ndi yaying'ono motsatira momwe madzi amayendera, kukana kwamadzi kumakhala kochepa, ndipo kutalika kwadzidzidzi kwa valve yachipata ndi yayikulu.
Globe Valve
Amagwiritsidwa ntchito poletsa kubwereranso kwa sing'anga, amagwiritsa ntchito mphamvu ya kinetic yamadzimadzi kuti adzitsegule okha, ndipo amangotseka pamene kutuluka kwapakati kumachitika. Nthawi zambiri imayikidwa potulutsira pampu yamadzi, potulutsira msampha wa nthunzi ndi malo ena komwe kusuntha kwamadzimadzi sikuloledwa. Ma valve owunika amagawidwa kukhala mtundu wa swing, mtundu wa pistoni, mtundu wokweza ndi mtundu wawafer.
Onani Vavu
Amagwiritsidwa ntchito poletsa kubwereranso kwa sing'anga, amagwiritsa ntchito mphamvu ya kinetic yamadzimadzi kuti adzitsegule okha, ndipo amangotseka pamene kutuluka kwapakati kumachitika.

Ma valve owunika amagawidwa kukhala mtundu wa swing, mtundu wa pistoni, mtundu wokweza ndi mtundu wawafer.
Sankhani mavavu a NSW
Pali mitundu yambiri ya ma valve a NSW, tingasankhire bwanji valve, Titha kusankha ma valve molingana ndi njira zosiyanasiyana, monga njira yogwiritsira ntchito, kuthamanga, kutentha, zinthu, ndi zina zotero. Njira yosankhidwa ndi iyi.
Sankhani ndi ma valve ntchito actuator
Ma valve a Pneumatic Actuator
Mavavu a pneumatic ndi ma valve omwe amagwiritsa ntchito mpweya woponderezedwa kukankhira magulu angapo a ma pistoni ophatikizana a pneumatic mu actuator. Pali mitundu iwiri ya makina oyendetsa pneumatic: rack ndi mtundu wa pinion ndi Scotch Yoke Pneumatic Actuator.
Mavavu amagetsi
Valavu yamagetsi imagwiritsa ntchito chowongolera chamagetsi kuti chiwongolere valavu. Mwa kulumikiza ku terminal ya PLC yakutali, valavu imatha kutsegulidwa ndikutsekedwa patali. Ikhoza kugawidwa m'magawo apamwamba ndi apansi, gawo lapamwamba ndi loyendetsa magetsi, ndipo gawo lapansi ndi valavu.
Ma valve pamanja
Pogwiritsa ntchito pamanja chogwirizira cha valve, gudumu lamanja, turbine, zida za bevel, ndi zina zambiri, magawo owongolera pamapaipi amadzimadzi amayendetsedwa.
Ma valve odzichitira okha
Valavu sichifuna mphamvu yakunja kuti iyendetse, koma imadalira mphamvu ya sing'anga yokha kuti igwiritse ntchito valve. Monga ma valve otetezera, ma valve ochepetsera kuthamanga, misampha ya nthunzi, ma valve oyendera, ma valve oyendetsa okha, ndi zina zotero.
Sankhani ndi mavavu ntchito
Valve yotsekedwa
Valavu yodulidwa imatchedwanso valve yotsekedwa. Ntchito yake ndi kulumikiza kapena kudula sing'anga mu payipi. Ma valve odulidwa amaphatikizapo ma valve a zipata, ma valve a globe, ma valve a pulagi, ma valve a mpira, ma valve a butterfly ndi diaphragms, ndi zina zotero.
Onani valavu
Vavu yowunika imatchedwanso valavu yanjira imodzi kapena valavu yoyendera. Ntchito yake ndikuletsa sing'anga mu payipi kuti isabwererenso. Valavu yapansi ya pampu yamadzi yotsekemera imakhalanso ya gulu la check valve.
Valve chitetezo
Ntchito ya valavu yotetezera ndikuletsa kuthamanga kwapakatikati mu payipi kapena chipangizo kuti zisapitirire mtengo wotchulidwa, potero kukwaniritsa cholinga cha chitetezo.
Ma valve owongolera: Mavavu owongolera amaphatikiza ma valve owongolera, ma throttle valves ndi ma valve ochepetsa kuthamanga. Ntchito yawo ndikuwongolera kuthamanga, kuyenda ndi magawo ena apakati.
Valve ya diverter
Ma valve diverter amaphatikizapo ma valve ogawa osiyanasiyana ndi misampha, ndi zina zotero. Ntchito yawo ndi kugawa, kulekanitsa kapena kusakaniza zofalitsa mu payipi.
