Uyintoni na umahluko phakathi kwendawo yehlabathi, nendawo yesango?

Ivalve ye-globe kwaye i-valve yesango ineempawu ezithile, kwaye zombini zinomsebenzi wokusika umbhobho, ke abantu bahlala bezibuza, Uyintoni umahluko phakathi kwendawo ye-gurober?

I-Globe, neSango leSango,Ibhotile yebhabhathane, Vala i-valve kunye nevalve yebhola yazo zonke izinto ezinokulawula izinto ezingenakuphikiswa kwiinkqubo ezahlukeneyo zemibhobho. Uhlobo ngalunye lwevalve lwahlukile ngenkangeleko, isakhiwo kunye nokusetyenziswa okusebenzayo. Kodwa ivalve ye-globe kwaye i-valve yesango ineempawu ezifanayo kubume, kwaye kwangaxeshanye inomsebenzi wokusika umbhobho, ke kuya kubakho abahlobo abaninzi abangaqhagamshelanga kwi-valve baya kudidanisa bobabini. Ngapha koko, ukuba ujonga ngononophelo, umahluko phakathi kwendawo ye-globe kwaye ivalve yesango inkulu. Eli nqaku liza kwazisa umahluko phakathi kwendawo yentlango kunye nendawo yesango.

1. Inkqubo eyahlukeneyo yokusebenza phakathi kwendawo ye-globe kunye ne-valve yesango
Xa ivalve ye-gurberve ivulwa kwaye ivaliwe, ijika ivili ngesandla, ivili ngesandla liya kujikeleza kwaye liphakamise ivili lesandla, kwaye isikhundla sevili ngesandla sihlala singaguquki.

IIrabha yerabha yeParubeInamazwe amabini kuphela: ukuvulwa ngokupheleleyo okanye ukuvalwa ngokupheleleyo ngokuvulwa okude kunye nexesha lokuvala; Ukubetha kwentshukumo ye-Globel incinci kakhulu, kwaye ipleyiti ye-valve ingapatshwa kwindawo ethile ngokuhamba kommiselo, ngelixa i-valve yesango inokunqunyulwa ngaphandle kweminye imisebenzi.

2. Umahluko wentsebenzo phakathi kwe-wilve ye-valve kunye ne-valve yesango
Ivalve ye-globe inokunqunyulwa kwaye isetyenziselwe ummiselo wokuhamba. The fluid resistance of the globe valve is relatively large, and it is difficult to open and close, but because the valve plate is short from the sealing surface, so the opening and closing stroke is short.

I-BS5163 I-Palve yesango inokuvulwa ngokupheleleyo kwaye ivaliwe. When it is fully opened, the flow resistance of the medium in the valve body channel is almost 0, so the opening and closing of the gate valve will be very easy, but the gate is far from the sealing surface, and the opening and closing time is long.

Ukuhamba kwexesha okungahambelaniyo kwe-vove ukuya kuzo zombini iindlela zinefuthe elifanayo, ukufakelwa akuzikho mfuneko yokungenisa elizweni kunye nokuthengisa ngaphandle, iphakathi inokuhamba kuzo zombini iindlela.

Ivalve ye-globe kufuneka ifakwe ngokungqongqo ngokungqinelana nendlela ye-valve yophawu lwe-valve. Kukho umdibaniso ocacileyo malunga ne-inlet kwaye uphume kwicala le-Globel Valve, kwaye ivala "ezintathu ukuba" zibambe ukuba i-valve yokuhamba yevalve isetyenziswa ukusuka phezulu.

4. Umahluko okwakhiweyo phakathi kwendawo ye-wilve kunye ne-valve yesango
Ubume be-valve yesango buya kuba nzima ngakumbi kune-valve yeglove. Ukusuka ekubonakaleni kwayo kufana nento ebonakalayo, ivuthuza lamasango, ngaphezu kwellove, kwaye ilokhwe yehlabathi mayibe lide kune-valve yesango. Ukongeza, i-valve yesango inayoInyuka isiqukwayeIsiqu sokunyuka, Ibhotile yeglove ayenzayo.
