Mtundu wa ma valve opangira mankhwala ndi malo ogwiritsira ntchito (ndi mtundu wa mphamvu)

Mtundu wa ma valve opangira mankhwala ndi malo ogwiritsira ntchito (ndi mtundu wa mphamvu)

Pambuyo pa kupangidwa kwa injini za nthunzi, m'zaka makumi awiri kapena makumi atatu zapitazi, chifukwa cha kufunikira kwa mafuta osakanizika, mafakitale a mankhwala, magetsi, mafakitale azitsulo, zombo, magetsi a nyukiliya, ndege ndi madera ena, zinthu zabwino zakhala zikuchitika. kwa mavavu, ndi mavavu kupanga mafakitale nawonso zosiyanasiyana mitundu.Monga valvekuwonetsa malo ogwiritsira ntchito mtundu wa valve yamagetsi ndi mphamvu yake.

Mtundu wa valve ya chomera chamankhwala ndi ntchito

1. Gawani molingana ndi momwe mungagwiritsire ntchito bwino komanso ntchito

(1) valavu yolumikizira: valavu yodulira imadziwikanso kuti valavu ya digito ya TELEVISION, ndipo zotsatira zake ndikulowa kapena kutulutsa sing'anga mupaipi. Ma valve odulidwa amaphatikizapo ma valve a globe, ma valve a globe, ma valve, ma valve, ma valve, ma diaphragms.

(2) valavu cheke: valavu cheke amatchedwanso valavu throttle kapena valavu cheke, zotsatira zake ndi kupewa sing'anga mu payipi kumtunda. Pampu ya centrifugal ya hygroscopic yochokera pansi pa pampu imakhalanso m'gulu la valavu.

(3) valavu: ntchito ya gulu lachitetezo cha valve ndikupewa kukakamiza kwa sing'anga mu payipi kapena zida ndipamwamba kuposa mtengo womwe watchulidwa, kuti mukwaniritse cholinga chachitetezo.

(4) valavu yoyang'anira: valavu yoyang'anira valavu imaphatikizapo valavu yoyendetsa, njira imodzi yothamanga ndi valve yoyendetsa mphamvu, zotsatira zake ndikusintha kupanikizika kwapakati, kutuluka kwathunthu ndi zina zitatu.

(5) valavu yolekanitsa: gulu la valavu la shunt limaphatikizapo ma valve amitundu yambiri ndi misampha ya nthunzi, ndi zina zotero, zotsatira zake ndikutumiza, kulekanitsa kapena kusakaniza sing'anga mu payipi.

2. Gulu ndi kalasi ya mapaundi

(1) Vacuum valve: imatanthawuza valavu yomwe kuthamanga kwake kuli kochepa kuposa kupanikizika kwa mumlengalenga.

(2) Valavu yotsika: imatanthawuza gulu la mapaundi PN ¡Ü 1.6mpa valve.

(3) valavu yapakati: imatanthawuza kuthamanga kwadzina PN ndi 2.5, 4.0, 6.4Mpa valve.

(4) Valavu yothamanga kwambiri: imatanthawuza valavu yogwira ntchito PN ya 10 ~ 80Mpa.

(5) valve yothamanga kwambiri: imatanthawuza valavu ya PN¡Ý100Mpa.

3. Sankhani malinga ndi kutentha kwa ntchito

(1) low temperature valve: for medium operating temperature t (1) otsika kutentha valavu: kwa sing'anga kutentha ntchito t

(2) valavu yotsika kutentha: kutentha kwapakati -100¡æ¡Ü T ¡Ü-40¡æ valve.

(3) Valavu yotentha yotentha: kutentha kwapakati -40¡æ¡Ü T ¡Ü120¡æ valve.

(4) Vavu yapakati ya kutentha: kwa kutentha kwapakati kwa 120¡æ

(5) valavu yotentha kwambiri: kutentha kwapakati kwa ntchito T> 450¡æ valve.

4. Gawani molingana ndi fomu yotsatsira

(1) Valavu yokhayo si mphamvu yakunja yolimbikitsa, koma ndi mphamvu ya sing'anga yokha kuti ipange malo a valve. Monga valavu, valavu yowongolera kuthamanga, msampha wa nthunzi, valavu yoyendera, valavu yodzilamulira yokha ndi zina zotero.

(2) Valavu yoyendetsa mphamvu yoyendetsa galimoto: valve yoyendetsa mphamvu yoyendetsa galimoto imatha kugwiritsa ntchito zipangizo zosiyanasiyana zamagetsi kuti zilimbikitse.

Valavu yowongolera magetsi: kudalira uinjiniya wamagetsi kulimbikitsa valavu.

Vavu ya pneumatic: valavu yoyendetsedwa ndi kuponderezedwa kwa mpweya.

Vavu ya Hydraulic: Vavu yoyendetsedwa ndi kuthamanga kwamadzi monga mafuta.

Kuonjezera apo, palinso zigawo zamagulu omwe ali pamwambawa a njira zoyendetsera galimoto, monga ma valve oyendetsa gasi.

(3) Valavu yamanja: valavu yamanja imadalira spindle, rocker, rod bar, sprocket unyolo, ndi anthu kuti aziwongolera kaimidwe ka valve. Pamene valavu yotsegula ndi kutseka torque ili yaikulu, gudumu kapena nyongolotsi yochepetsera mphutsi ikhoza kukhazikitsidwa pakati pa spindle ndi mpando. Ngati ndi kotheka, ma cardan ophatikizana ndi ma shaft ozungulira angagwiritsidwenso ntchito pochita ntchito yayitali.

5, malinga ndi gulu laling'ono la mainchesi

(1) Vavu yaing'ono yaing'ono: valavu ya DN¡Ü40mm.

(2) Vavu yapakati m'mimba mwake: valavu ya DN ya 50 ~ 300mm.

(3) Vavu yayikulu m'mimba mwake: valavu ya DN ya 350 ~ 1200mm.

(4) Vavu yokulirapo: valavu yokhala ndi m'mimba mwake mwadzina DN¡Ý1400mm.

6. Gawani molingana ndi mtundu wa dongosolo

(1) mawonekedwe a valve: mbali zotsegulira ndi zotsekera (pistoni valve) zimayendetsedwa ndi mpando pamphepete mwa valavu yachipata chapamwamba kuti asinthe kayendetsedwe ka thupi;

(2) mawonekedwe a valavu ya pulagi: magawo otsegulira ndi otseka (valavu yapadziko lonse lapansi) amakankhidwa ndi mpando wa valavu motsatizana ndi kupindika kwa valavu yapakhomo kuti asinthe kayendedwe ka thupi;

(3) pulagi valavu: kutsegula ndi kutseka mbali (cone pulagi kapena mpira) mwamphamvu kuzungulira olamulira ake kasinthasintha;

(4) valavu yozungulira: mbali zotsegula ndi zotsekera (valavu ya pistoni) mwamphamvu kuzungulira tsinde kunja kwa kasinthasintha wa mpando;

(5) mzere wa agulugufe: mbali zotsegulira ndi zotsekera (disk) zimazungulira mwamphamvu kuzungulira tsinde lokhazikika mu valve yothamanga kwambiri;

(6) Mzere wa mpope wozungulira mbale: mbali zotsegula ndi zotsekera zikuyenda molunjika ku njira yachitetezo cha bisector.

7. Gawani molingana ndi njira yolumikizira

(1) Valavu yolumikizira: gulu la valve lili ndi ulusi kapena ulusi wa chitoliro, wolumikizidwa ndi chitoliro.

(2) Vavu yolumikizira yolumikizira: thupi la vavu lili ndi mbale ya flange, yolumikizidwa ndi mapaipi.

(3) magetsi kuwotcherera valavu kugwirizana: valavu thupi muli magetsi kuwotcherera msoko, ndi kuwotcherera chitoliro kugwirizana.

(4) Valavu yolumikizira: valavu imakhala ndi cholumikizira ndipo imalumikizidwa ndi chitoliro.

(5) Valavu yolumikizira yolumikizana ndi manja: ndi kusankha kwa chitoliro cholumikizira chamtundu wa manja.

(6) Valavu yolumikizira: njira yolumikizira yomwe valavu ndi mapaipi mbali zonse amamangiriridwa pamodzi nthawi yomweyo ndi bawuti yapansi.

8, malinga ndi valavu thupi zakuthupi

(1) Vavu yachitsulo: thupi la valve ndi ziwalo zina zimapangidwa ndi zitsulo. Monga valavu yachitsulo ya nkhumba, valavu yachitsulo ya carbon, valavu yachitsulo, valavu yamkuwa, valavu ya aluminiyamu, valavu ya aluminiyamu, valavu ya titaniyamu, valavu ya Monel alloy, etc.

(2) valavu yopanda zitsulo: thupi la valve ndi ziwalo zina zimapangidwa ndi zinthu zopanda zitsulo. Monga valavu pulasitiki, valavu ceramic, valavu alimbane, valavu FRP anticorrosive, etc.

(3) zitsulo zachitsulo valavu thupi akalowa valavu: valavu thupi mawonekedwe kapangidwe zinthu zitsulo, kapangidwe mkati kumene kukhudzana ndi sing'anga makamaka pamwamba akalowa, monga distribuerar mafuta, valavu pulasitiki, valavu ceramic, etc..

Awiri, mankhwala chomera valavu lapamwamba

Tsegulani ndi kutseka mtundu: kulumikiza kapena kulankhula fluidity madzi mu ac chitoliro;

Kusintha mtundu: sinthani kuchuluka kwa kuthamanga ndi kuthamanga kwachubu;

Mtundu wa valavu ya Throttle: pangani madziwo molingana ndi valavu mutayambitsa kupanikizika kwakukulu kwa gasi;

Mitundu ina: a. kutsegula ndi kutseka kwathunthu basi B. kusunga mphamvu zina zogwirira ntchito C. chitoliro chotsekereza ngalande.
