Thevalavuakuyenera kuwonetsetsa kuti zosowa zamapaipi a valve zikuyenda bwino komanso modalirika ngati gawo lofunikira la dongosolo.Choncho, mapangidwe a valve ayenera kukwaniritsa zofunikira zonse za valavu pogwiritsira ntchito, kupanga, kukhazikitsa, ndi kukonza komanso kupanikizika, kutentha, zowonongeka, zamadzimadzi zomwe zimagwiritsidwa ntchito, ndi ntchito, kupanga, ndi kukonza.

Za avalavukamangidwe kachitidwe koyenera, kayenera kufotokoza zambiri zaukadaulo zomwe zapatsidwa, kapena "kuyika kwapangidwe".

Basic Information kutivalavu"Design input" iyenera kukhala:

ntchito kapena mtundu wa valve

kutsika kwa kupanikizika kwa ntchito

tsamba lapakati

Maonekedwe a thupi ndi mankhwala a sing'anga (corrosivity, flammability, toxicity, state of matter, etc.)

Zabwino mwadzina

Kukula kwa kamangidwe

Fomu yolumikizana ndi payipi

Momwe valavu imagwirira ntchito (pamanja, zida, nyongolotsi, magetsi, pneumatic, hydraulic, etc.)

Tsatanetsatane wotsatirawu ndi ukadaulo wazidziwitso ziyenera kumvetsetsedwa musanayambe kupanga ma valve ndi zojambula zomanga:

Kuthamanga kwa ma valve ndi coefficient of fluid resistance

mlingo ndi nthawi ya kutsegula ndi kutseka kwa valve

katundu wa mphamvu yoyendetsa (AC kapena DC, voliyumu, kuthamanga kwa mpweya, etc.)

Malo ogwirira ntchito ndi kukonza ma valve (monga ngati saphulika kapena kumadera otentha, ndi zina zotero)

Malire a Kunja Kwakunja

Kulemera Kwambiri

zofunikira za chivomerezi

Pulogalamu Yopanga Ma Valve

Kukonzekera kwa mapangidwe ndi chitukuko

siteji ya chitukuko cha mapangidwe

Zochita zowunikiridwa, kutsimikizira, ndi kutsimikizira zogwirizana ndi gawo lililonse la mapangidwe ndi chitukuko

Ulamuliro ndi Udindo pa Kupanga ndi Kupititsa patsogolo

chothandizira pakupanga ndi chitukuko

Zofunikira pakugwira ntchito ndi magwiridwe antchito

Malamulo ndi zofunikira zamalamulo kuti zigwiritsidwe ntchito

Zomwe zimachokera ku mapangidwe akale, ogwirizana

Zinthu zowonjezera pakupanga mapangidwe

Zopangidwa ndi mapangidwe ndi chitukuko

kukwaniritsa zofunikira pakupanga ndi chitukuko

Perekani zidziwitso zofunikira pakugula, kupanga, ndi kupereka chithandizo.

Tchulani kapena tchulani zofunika kuvomereza malonda.

imatchula zinthu zomwe zimafunikira kuti zigwiritsidwe ntchito moyenera komanso moyenera.
