Yintoni isakhiwo sevali yebhola?

Ivalve yebholaluhlobo lwevalve enendawo yokuvula kunye nokuvala. Inesakhiwo secaces kunye nemisebenzi eyahlukeneyo. Isakhiwo se-valve yebhola sihlalutywa kwimiba emithathu: izinto eziphambili, imigaqo-siseko yokusebenza, kunye nokuhlelwa kwesakhiwo

icandelo eliphambili

Ivalve yebhola iqulunqwe ikakhulu yibhulukhwe yevalve, umzimba webhola, isitulo sevali, isiqu se-valve, kunye nesixhobo esisebenzayo. I-veli ibhulukhwe yomzimba ophambili yoqhagamshelo lwepayipi, uninzi lwenziwe ngentsimbi okanye ngentsimbi engenasibala, libonelela ngenkxaso yesakhiwo; Inqanaba yibhola yensimbi kunye nomngxunya, olawula ukuhamba kwephakathi ngokujikeleza i-90 ° Ukujikeleza kwe-90 °; Isihlalo se-valve samkele itywina elithambileyo (njengokuhamba kwe-ptfe) okanye itywina elinzima (elensi lentsimbi), elinamathele kumphezulu wendawo yokutywina; I-valve stem iqhagamshelwe kwisixhobo esisebenzayo kunye nenqanaba lokudlulisela amandla ojikelezo; Isixhobo esisebenzayo siquka isibambo, igiya ye-sotm, umbane okanye i-pneumatic activator, eqhuba ibhola ijikeleze.

UMGAQO-NKQUBO OMPILO

I-valves yebholaUkufezekisa unxibelelwano oluphakathi kunye nokuqhawulwa ngokujikeleza ibhola. Kwimeko evulekileyo ngokupheleleyo, umngxunya ojikelezayo uhambelana ne-pipeliel Axis, kwaye i-Medium ihamba engacacanga; Kwimeko evaliweyo ngokupheleleyo, indawo ejikeleze i-90 ° kunye nomngxunya ojikelezayo kwi-Pipeliel Axis, ivimba ukuhamba kwephakathi. Ezinye iivali zebhola (ezinjengeValves ezivaliweyo) zifezekisa umsebenzi wokuhambahamba ngokwenza i-notch ebiweyo kwi-v-vered kumphezulu we-valve.

Ukwahlulakhiwo kwesakhiwo

Ngokwendlela yenkxaso yebhola, i-valves yebhola yahlulwe yangamahlunza edadayo kwaye ilungisiweI-valves yebhola. Ibhola yevali yebhola edadayo ayinayo ishafti eqingqiweyo kwaye ixhomekeke kuxinzelelo lwe-Wiind ukucofa isihlalo seVootlet ukuze sifezekise ukutywina. Isakhiwo silula kodwa silungele imeko ephakathi neliphantsi; Ibhola ye-valve yebhola eqingqiweyo ihleli kwinkcitho nge-veli engaphezulu nezantsi kwe-valve, kwaye uxinzelelo oluphakathi luthwale. Isihlalo sesihlalo se-valve sincinci, itywina lizinzile, kwaye lilungele uxinzelelo oluphezulu kunye nemeko enkulu yedayamere. Ukongeza, ngokwendlela yokutywina, inokwahlulwa ibe ziivalves zebhola ezitywiniweyo (ze-zero ukuvuza, zilungele imithombo yeendaba ezinobunzima) kunye neevali ezinzima zebhola (amaqondo obunzima obuphakathi kunye nokunganyakelwa koxinzelelo oluphezulu); Ngokutsho kohlobo lwesitishi sokuhamba, linokwahlulwa kwiivalves zebhola ezigcweleyo (kunye ne-adreture yokuhamba-hamba ngokuhambelana nombhobho wepayipi) kwaye incitshisiwe ivali yebhola ekhatywayo; Ngokwesikhundla sejelo, inokohlulwahlulwahlulwahlulwahlulwa ibe ngqo, indlela ezintathu (i-T-Drix ye-T-Dedrion kunye nokudityaniswa, ukusasazwa kwe-L-Frinta), kunye neeHallers zeAngle elungileyo.
