Intshayelelo yemowudi yoqhagamshelo eqhelekileyo ye-valve kunye nombhobho

Ingaba unxibelelwano phakathi kweivalvekwaye iumbhobhoOkanye izixhobo zichanekile kwaye kufanelekile ukuba ichaphazele ngokuthe ngqo amathuba evali ye-pipelil valve, ukuthobeka, kuncipha kunye nokuvuza.

1. Unxibelelwano lweflethi

Unxibelelwano-1

Unxibelelwano olubiweyo ngumzimba wevali-valve ngeflethi kwiziphelo zombini, ezihambelana neflethi kumbhobho, ngokuthoba iflethi efakwe kumbhobho. Unxibelelwano olubiweyo ngolona hlobo lusetyenziswayo lonxibelelwano oluqhelekileyo lwe-valve. Iiflethi zine-quisx (i-RF), inqwelomoya (FF), i-Convex kunye neConcave (MF) kunye namanye amanqaku. Ngokwembonakalo yomphezulu odibeneyo, onokwahlulwahlulwahlulwahlulwahlulwa kwezi ntlobo zilandelayo:

(1) Uhlobo olugudileyo: kwivali enoxinzelelo olusezantsi. Ukulungiswa kufanelekile;

(2) I-Concave kunye nohlobo lwe-cowx

.

.

(5) Uhlobo lwelensi: i-gasket ikwimo yelensi, eyenziwe ngentsimbi. Isetyenziselwe i-valves ephezulu yoxinzelelo olunoxinzelelo lokusebenza

2.Amalungu eWeldling

Unxibelelwano-2

3.Unxibelelwano olukhwesiweyo

Unxibelelwano-3

Unxibelelwano oluqhutywa yindlela equkayo yonxibelelwano kwaye ihlala isetyenziselwa i-valve ezincinci. Ibhunga le-valve liqwalaselwe ngokwentambo esemgangathweni, kwaye zimbini iintlobo zentambo yangaphakathi kunye nentambo yangaphandle. Ihambelana nentambo kumbhobho. Unxibelelwano olusenziwa luhlu lwahlulwe lwaziimeko ezimbini:

(1) Ukutywinwa ngokuthe ngqo: Imisonto yangaphakathi nengaphandle idlala ngqo indima yokutywina. Ukuze uqiniseke ukuba i-joent ayivuleki, ihlala i-oyile ekhokelayo, i-hemp kunye ne-ptfere grew yokugcwalisa ibhanti yokugcwalisa ibhanti. Phakathi kwazo, iBhowd Right Greyitha isetyenziswe ngokubanzi. Esi sixhobo sinokungaxhathisi kakuhle, ukusebenza kakuhle, kulula ukuyisebenzisa kwaye kugcinwe, xa kushenxiswa ifilimu engakhange ichaphazele i-oyile, i-hemp.

.

Zintlanu iindidi zemisonto esetyenziswayo:

(1) intambo eqhelekileyo ye-metric.

(2) i-intshi eqhelekileyo;

(3) intambo intambo yokutywina;

.

(5) Imithombo yomgangatho oqhelekileyo waseMelika.

Intshayelelo jikelele yile ilandelayo:

① I-ISO YEMIQATHANGO YOKUGQIBELA I-ISO228 / 1, din 259, intambo yangaphakathi nangaphandle, ikhowudi g okanye i-PF.

② Umgangatho weSoJa7 / 1, Din 3999, I-Din21, i-BSE TOTE YOBUGCISA, I-BORE YENDALO EQHELEKILEYO, IKHODI BSP.P / I-RP / PS;

③ I-Bhritine i-Iso7 / 1, BS21, i-Bipper yangaphakathi nengaphandle, ikhowudi ye-Pt okanye i-BSP.tr okanye i-RC;

Umgangatho waseMelika I-ANI B21, i-Toper yangaphakathi nengaphandle, ikhowudi ye-GP Tr ngokudibeneyo ekubhekiselwe kuyo njengee-bps amazinyo.

Kukho iintlobo ezintlanu zemitya esemgangathweni ye-United States kwi-United States: I-NPT yokusetyenziswa ngokubanzi, i-NPSC ye-ricings eqondile, i-NPRR yokukhokela unxibelelwano lwe-rod, i-NPRM ye-Poipe uqhagamshelo lwe-radical (kunye ne-NPSL yoomatshini), kunye ne-NPSL yoomatshini Ukuqhutywa konxibelelwano olufanelekileyo lwezinto ezivaliweyo. Yeyona ntambo ye-pubile engafunekiyo (N: Umgangatho weSizwe waseMelika;

4. Uqhagamshelo

Unxibelelwano-4

Unxibelelwano kunye nokutywina komkhono kukuba xa i-nati iqine, umkhono uphantsi koxinzelelo, ukuze i-bile incinci kudonga lombhobho, kwaye i-cone engaphandle ye-Sleeve ivaliwe ngokuqinileyo ngekhodi ye Umzimba odibeneyo uphantsi koxinzelelo, ukuze kungathintela ngokuphumelela ukuvuza. NjengeI-valves yesixhobo.Izibonelelo zolu hlobo lonxibelelwano zezi:

(1) Umthamo omncinci, ubunzima bokukhanya, ubume obulula, ngokudibeneyo kunye nendibano;

.

(3) unokukhetha iintlobo ezahlukeneyo zezixhobo, kufanelekile ukuthintelwa;

(4) Ukuchaneka koMatshini akuphezulunga;

(5) Kulula ukufaka kwindawo ephezulu.

I-5. Qhagamshela

Unxibelelwano-5

Yindlela yoqhakamshelwano ekhawulezayo efuna ii-bolts ezimbini kuphela kwaye ilungele i-valves ephantsi yoxinzelelo ezihlala zisuswa.
