Ulwazi oluyisisekelo lwevalvu nokuhlukaniswa (a)i-valve imininingwane! Nakhu konke ongakwazi ngama-Angle valves
I-Valve inguwoyela, i-Ding yamakhemikhali, isiteshi samandla, ipayipi elide lokutholwa, ukwenziwa kwamaphepha, imboni yenuzi, zonke izinhlobo zobunjiniyela be-cryogenic, i-aerospace kanye nowoyela wasolwandle kanye nezinye izingxenye zokulawula ukugeleza kohlelo lwezokuthutha, ngokuphambukisa, ukunqanyulwa, ukulawulwa, i-throttling, ivimbele imisebenzi ephikisanayo, ephambukisayo noma yokugeleza kwengcindezi. Amavaluvu okulawula uketshezi ahluka ngokwehlukahlukana nangokucaciswa kwawo kusukela kumadivayisi alula wokunqamula ukuya ezinhlelweni zokulawula ezizenzakalelayo eziyinkimbinkimbi kakhulu. I-valve incike endleleni yokucwilisa noma emhlophe enyakazayo ukuze yenze izingxenye zayo zokuvula nokuvala ukuze ziphakamise, zishelele, zijikeleze noma zinyakaze, ukuze kushintshwe usayizi wendawo yokugeleza kwayo, ukuze kuzuzwe umsebenzi wokulawula.
I-Valve inguwoyela, i-Ding yamakhemikhali:, isiteshi samandla, ipayipi elide lokutholwa, iphepha, imboni yenuzi, zonke izinhlobo zobunjiniyela be-cryogenic, i-aerospace kanye nowoyela wasolwandle kanye nezinye izingxenye zokulawula ukugeleza kohlelo lwezokuthutha, ngokuphambukisa, ukunqanyulwa, ukulawulwa, ukugoqa. , vimbela imisebenzi ephikisanayo, ye-shard noma yokusiza ingcindezi yokugeleza.
Amavaluvu okulawula uketshezi ahluka ngokwehlukahlukana nangokucaciswa kwawo kusukela kumadivayisi alula wokunqamula ukuya ezinhlelweni zokulawula ezizenzakalelayo eziyinkimbinkimbi kakhulu. Usayizi ojwayelekile wamavalvu usukela kumavalvu ensimbi amancane kakhulu kuye kumavalvu wepayipi wezimboni anosayizi abangafika ku-10 m futhi anesisindo samathani angamashumi. Amavavu angasetshenziswa ukulawula umoya, amanzi, isitimu, zonke izinhlobo zodaka lwemidiya yamakhemikhali egqwalayo, uwoyela, insimbi ewuketshezi noketshezi olukhipha imisebe nezinye izinhlobo zokugeleza koketshezi. Ukucindezela kokusebenza kwe-valve kungaba kusuka ku-1.3× 10-3MPa kuya ku-1000MPa. Ukushisa okusebenzayo kusuka -269 ℃ kuya ku-1430 ℃ izinga lokushisa eliphezulu. Ukulawula i-valve kungathatha izindlela ezihlukahlukene zokudlulisa, ezifana ne-manual, ugesi, i-pneumatic, i-hydraulic, i-electric noma i-electric hydraulic linkage kanye ne-electromagnetic drive; Kungase futhi kube ngaphansi kwesenzo sengcindezi, izinga lokushisa noma ezinye izinhlobo zokuzwa umnsalo, ngokuya ngezidingo ezinqunywe kusengaphambili zesenzo, noma vele uvule noma uvale. I-valve incike endleleni yokucwilisa noma emhlophe enyakazayo ukuze yenze izingxenye zayo zokuvula nokuvala ukuze ziphakamise, zishelele, zijikeleze noma zinyakaze, ukuze kushintshwe usayizi wendawo yokugeleza kwayo, ukuze kuzuzwe umsebenzi wokulawula.
1. Ukuhlukaniswa kwama-valve Izinhlobonhlobo ze-Valve, ngokuthuthuka okuqhubekayo kwazo zonke izinhlobo zamasethi aphelele wokugeleza kwenqubo yemishini nokusebenza, izinhlobo zama-valve zisakhula, futhi kunezindlela ezihlukahlukene zokuhlukanisa.
1, ngokusho kwe-othomathikhi kanye nezigaba zokushayela

Imininingwane yevalvu! Nakhu konke ongakwazi ngama-Angle valves
Uma i-Angle valve ivuza, futhi kutholakala ukuthi umongo we-Angle valve uphukile, ingashintsha kuphela i-Angle valve. Uma kutholakala ukuthi indawo yokuvuza ye-engeli ye-valve iku-interface, vele ubophe kabusha ibhande lempahla eluhlaza bese uliqinisa. Empilweni yangempela, i-valve engunxantathu ku-heater yamanzi yaqhuma ngokushesha nje lapho indlu entsha yabanikazi abathile isiqediwe, okwabangela ukuba amapayipi avuze futhi akhukhule phansi, ikhabethe le-TV, ikhabethe lezingubo, njll. Lokhu kwenzeka, ngokuvamile ngenxa yokuthi izinga i-Angle valve ayibangelwa. Ngakho-ke, ohlelweni lokuhlobisa ikhaya, kufanele sinake ekukhethweni kwekhwalithi enhle ye-Angle valve ungabi ne-penny ehlakaniphile futhi iwubuwula.
