Momwe mungasankhire valavu yoyenera yotumizidwa kunja molondola

(Kufotokozera mwachidule)Mavavu otumizidwa kunja makamaka amatanthauza ma valve ochokera kumitundu yakunja, makamaka mitundu yaku Europe, America ndi Japan.

Mavavu otumizidwa kunja makamaka amatanthauza ma valve ochokera kumitundu yakunja, makamaka mitundu yaku Europe, America ndi Japan. Mitundu ya mavavu amtunduwu imaphatikizapo mavavu a mpira, ma valve otumizidwa kunja, ma valve oyendetsa kunja, mavavu agulugufe omwe amatumizidwa kunja, ma valve ochepetsera mphamvu, ma valve a solenoid, ndi zina zotero, ndipo Pali magawo ambiri monga mankhwala, kuthamanga, kutentha, zinthu , njira yolumikizira, njira yogwirira ntchito, etc. Ndikofunikira kusankha valve yoyenera malinga ndi zosowa zenizeni ndi makhalidwe a mankhwala.
1. Makhalidwe a valve yotumizidwa kunja amaphatikizapo makhalidwe ogwiritsira ntchito ndi mawonekedwe apangidwe

1. Gwiritsani ntchito mawonekedwe a ma valve omwe atumizidwa kunja

Makhalidwe ogwiritsira ntchito amatsimikizira ntchito yaikulu yogwiritsira ntchito komanso kukula kwa valve. Makhalidwe ogwiritsira ntchito valve ndi awa: gulu la valve (valavu yotsekedwa yozungulira, valve yoyendetsa, valve chitetezo, etc.); mtundu wazinthu (valavu yachipata, valavu yapadziko lonse lapansi, valavu yagulugufe, valavu ya mpira, etc.); valavu Zida za zigawo zikuluzikulu (vavu thupi, bonnet, tsinde valavu, valavu disc, kusindikiza pamwamba); valavu kufala mode, etc.

2. Makhalidwe apangidwe

Makhalidwe amapangidwe amatsimikizira zina mwamapangidwe a ma valve, kukonza, kukonza ndi njira zina. Makhalidwe apangidwe akuphatikizapo: kutalika kwapangidwe ndi kutalika kwa valavu, mawonekedwe ogwirizanitsa ndi payipi (kugwirizana kwa flange, kugwirizana kwa ulusi, kugwirizana kwachitsulo, kugwirizana kwa kunja kwa Threaded, kugwirizana kotsiriza, etc.); mawonekedwe a malo osindikizira (mphete ya inlay, mphete ya ulusi, pamwamba, kuwotcherera kutsitsi, thupi la valve); kapangidwe ka tsinde la valve (ndodo yozungulira, ndodo yonyamulira), etc.

Chachiwiri, masitepe kusankha valavu

Kufotokozera cholinga cha valavu mu zipangizo kapena chipangizo, ndi kudziwa mmene valavu ntchito: sing'anga yoyenera, kuthamanga ntchito, kutentha ntchito, etc.; mwachitsanzo, ngati mukufuna kusankha German LIT stop valve, onetsetsani kuti sing'anga ndi nthunzi, ndipo mfundo ntchito ndi 1.3Mpa, kutentha ntchito ndi 200 ℃.

Dziwani m'mimba mwake mwadzina ndi njira yolumikizira payipi yolumikizidwa ndi valavu: flange, ulusi, kuwotcherera, etc.; mwachitsanzo, sankhani valavu yolowera ndikutsimikizira kuti njira yolumikizira ndi flanged.

Dziwani njira yogwiritsira ntchito valavu: manual, magetsi, electromagnetic, pneumatic kapena hydraulic, electro-hydraulic linkage, etc.; mwachitsanzo, valavu yotseka -

Dziwani zinthu za chipolopolo chosankhidwa cha valve ndi ziwalo zamkati malinga ndi sing'anga, kuthamanga kwa ntchito ndi kutentha kwa payipi: chitsulo chosapanga dzimbiri, chitsulo cha carbon, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, asidi wosapanga dzimbiri - chitsulo chosagwira ntchito, chitsulo chosungunuka, chitsulo , ductile cast iron, copper Alloy, etc.; monga zitsulo zotayidwa zosankhidwa kuti valavu yapadziko lonse lapansi.

Sankhani mtundu wa valavu: valve yotsekedwa yotsekedwa, valve yoyendetsa, valve yotetezera, etc.;

Dziwani mtundu wa valavu: valavu yachipata, valavu yapadziko lonse, valavu ya mpira, valavu ya butterfly, valve throttle, valve chitetezo, valve kuchepetsa kuthamanga, msampha wa nthunzi, etc.;

Tsimikizirani magawo a valavu: Kwa ma valve odziyimira pawokha, choyamba dziwani kukana kovomerezeka, kutulutsa mphamvu, kuthamanga kwa msana, ndi zina zambiri malinga ndi zosowa zosiyanasiyana, ndiyeno dziwani kuchuluka kwa mapaipi ndi kukula kwa dzenje la mpando wa valve;

Dziwani magawo a geometric a valavu yosankhidwa: kutalika kwapangidwe, mawonekedwe a kugwirizana kwa flange ndi kukula kwake, kutalika kwa valve mutatha kutsegula ndi kutseka, kulumikiza kukula kwa dzenje ndi nambala, kukula kwa ndondomeko ya valve, ndi zina zotero;

Gwiritsani ntchito zidziwitso zomwe zilipo: zolemba zama valve, zitsanzo zama valve, ndi zina.

Chachitatu, maziko kusankha mavavu

Cholinga, mikhalidwe yogwirira ntchito, ndi njira zowongolera za valve yosankhidwa;

Chikhalidwe cha sing'anga ntchito: kuthamanga ntchito, kutentha ntchito, dzimbiri ntchito, kaya lili ndi particles olimba, kaya sing'anga ndi poizoni, kaya ndi choyaka kapena kuphulika sing'anga, mamasukidwe akayendedwe a sing'anga, etc.; mwachitsanzo, ngati mukufuna kusankha valavu ya solenoid yochokera kunja kuchokera ku LIT, sing'anga Kuwonjezera pa malo oyaka ndi kuphulika, kuphulika-umboni wa solenoid valve nthawi zambiri amasankhidwa; Chitsanzo china ndikusankha valavu ya mpira ya German Lit LIT. Sing'anga imakhala ndi tinthu tating'onoting'ono, ndipo valavu ya V-yowoneka bwino - yosindikizidwa imasankhidwa nthawi zambiri.

Zofunikira pamayendedwe amadzimadzi a valve: kukana kwamadzi, kutulutsa mphamvu, mawonekedwe otaya, mulingo wosindikiza, ndi zina zambiri;

Zofunikira pakuyika miyeso ndi miyeso yakunja: m'mimba mwake mwadzina, njira yolumikizira ndi miyeso yolumikizana ndi payipi, miyeso yakunja kapena zoletsa zolemetsa, etc.;

Zofunikira zowonjezera pa kudalirika kwa mankhwala a valve, moyo wautumiki, ndi kuphulika-umboni wa machitidwe a zipangizo zamagetsi (zindikirani posankha magawo: Ngati valavu iyenera kugwiritsidwa ntchito pofuna kulamulira, zotsatirazi ziyenera kutsimikiziridwa: njira yogwiritsira ntchito, kutuluka kwakukulu ndi kochepa. zofunikira , Kutsika kwapakati kwa kayendedwe kabwino, kutsika kwapakati pamene kutseka, kutsika kwakukulu ndi kutsika kochepa kwa valve).

Malinga ndi zomwe tazitchula pamwambapa-zimene tatchulazi ndi masitepe osankha ma valve, ndikofunikira kumvetsetsa bwino momwe mkati mwa mitundu yosiyanasiyana ya mavavu mukusankha ma valve moyenera komanso moyenera, kuti mupange chisankho choyenera pa valve yomwe mumakonda.

Ulamuliro waukulu wa payipi ndi valavu. Ma valve otsegula ndi kutseka amayang'anira kayendetsedwe ka kayendedwe ka sing'anga mu payipi. Maonekedwe a njira yoyendetsera valve imapangitsa kuti valavu ikhale ndi khalidwe linalake loyenda. Izi ziyenera kuganiziridwa posankha valavu yoyenera kwambiri pamapaipi.
Fotokozerani mwachidule ndi kufotokoza mwachidule zinthu zingapo zazikulu za chisankho: dziwani ntchito ya valve yosankha, kutsimikizira kutentha ndi kupanikizika kwapakati, kutsimikizira kuthamanga kwa valve ndi m'mimba mwake yofunikira, kutsimikizira zakuthupi za valve, ndi njira ya opaleshoni;
