Izinto eziluncedo zetywina elinzima lesakhiwo soxinzelelo lwebhola

Isivingco esinoxinano oluphezulu soxinzelelo lwebhola sineendawo ezimbini zokutywina. Okwangoku, izinto zokutywina zomhlaba zevalvu zebhola zisetyenziswa kakhulu kwiiplastiki ezahlukeneyo. Zineempawu ezifanelekileyo zokutywina kwaye zinokutywinwa ngokupheleleyo. Zikwasetyenziswa ngokubanzi kwiinkqubo zokucoca. Ukusebenza okulula, ukuvulwa ngokukhawuleza kunye nokuvalwa, kufuneka kuphela ukujikeleza iidigri ezingama-90 ukusuka kutshintsho olupheleleyo ukuya kutshintsho olupheleleyo, olulungele ukulawula umgama omde.

I-valve yesinyanzelo esine-high-pressure ye-valve kulula ukuyigcina, kwaye ubume bevalve yebhola bulula. Isangqa sokutywina sihamba ngokubanzi, kwaye kulula ngakumbi ukuhlahlula kunye nokutshintsha. Xa ivulwe ngokupheleleyo okanye ivalwe ngokupheleleyo, umphezulu wokutywinwa kwebhola kunye nesihlalo sevalve uhlukaniswe phakathi. Xa udlula ngokuphakathi, ayizukubangela ukubola komgangatho wokutywina wevalve. Ingasetyenziswa kwizicelo ezahlukeneyo, ukusukela kwincinci ukuya kwiimilimitha ezimbalwa ubukhulu, ukusuka kwindawo ephezulu ukuya koxinzelelo oluphezulu. Ivalve yebhola ingasetyenziswa kumajelo eendaba aneesuntswana ezixhonyiweyo ezimileyo kuba inezinto zokosula ngexesha lokuvula nokuvala. Iibhola zebhola ezinoxinzelelo oluphezulu zisetyenziswe ngokubanzi kwi-petroleum, imichiza, amandla ombane, isinyithi, ukwenza iphepha kunye namanye amashishini.

Iivalvu zebhola ezinoxinzelelo oluphezulu ziqulathe umzimba wevalve, ikhava yevalve, ibhola, isihlalo sevalve kunye nesiqu sevalve. Xa isetyenziswa, ibhola emazantsi evalve iqhutywa ukujikeleza ngokujikeleza isitshixo sevalve, ukuze umngxuma kwibhola uhambelane okanye udibanise indlela yokuhamba kwevalve, ukwenzela ukuqonda ukuvulwa okanye ukuvalwa ivelufa yebhola. Ngenxa yokuxubana phakathi kwebhola kunye nesitulo se-valve ngexesha lokujikeleza, ukunxiba okunzima kunokukhokelela ekuvuza, okunciphisa ukuthembeka kwevalve yebhola kunye nokunciphisa ubomi benkonzo yevalvu yebhola.

Nangona kungekho venali yebhola yokunxiba, ubume bayo bunzima ngakumbi, kwaye akukho lula kakhulu ukuyisebenzisa nokugcina. Ukuze soyise iziphene zetekhnoloji esele ikho, siphuhlise uhlobo olutsha lwevalve yoxinzelelo lwebhola ephezulu engatywinwanga kwindawo yokutywina. Imodeli yokusebenziseka ibonelela ngesitywina esiqinileyo sevali yebhola enesakhiwo esifanelekileyo, akukho kunxiba kwindawo yokutywina yevalve yebhola kunye nomphezulu wokutywinwa kwesihlalo sevalve, ubomi obude benkonzo, ukusetyenziswa okufanelekileyo kunye nokugcinwa, ukumelana nobushushu, ukuphakama uxinzelelo kunye nokutywina ukusebenza.

Umzimba we-hard-seal ye-valve yoxinzelelo lwebhola exhotyiswe ngebhola yomngxunya. Isiphelo esiphezulu sebhola siqhagamshelene nendlela yokuhambisa isiqu sevalve kunye nebhola. Isiphelo esisezantsi sebhola sixhotyiswe ngezikhonkwane zesikhokelo kunye neebhonethi zekhohlo nasekunene ezinamajelo okuhamba kufakelwe kumacala omabini omzimba wevalve. Izitulo zasekhohlo nezasekunene zifakelwe ngokulandelelanayo kumacala omabini esembozo sevelufa sasekhohlo nasekunene kunye nebhola yevali. Isiphelo sangaphandle sesihlalo sinikezelwe ngesihlalo sokuhlala, kwaye iringi yokutywina icwangcisiwe phakathi kwesihlalo kunye nesembozo sevalve. Izikhuselo zevalve zangasekhohlo nasekunene zibonelelwa ngemihlaba exhasayo enxibelelana nomphezulu webhola yevalve, ephawulwa ngemijelo yomoya kumphezulu webhola yevalufa kunye nokutywina imiphezulu kugqunywe ngaphezulu kumphezulu webhola yevali, kunye nemijelo yokujikeleza ehambelana nayo Ukutywina imiphezulu kugqityiwe kwincopho yokuphela yezihlalo ze-valve zasekhohlo nasekunene, ngokwahlukeneyo. .
