Kutshanje, iworkshop yeJinbin igqibe ibhetshi yeeodolo zeevalvu zebhola ezidityanisiweyo ngokupheleleyo. Iivalve yebhola edityanisiweyo ngokupheleleyoyamkela ulwakhiwo oludityanisiweyo oludityanisiweyo. Umzimba wevalvu wenziwa ngokudibanisa iihemispheres ezimbini. Inxalenye yangaphakathi engundoqo yibhola enesetyhula ngomngxuma, edityaniswe ne-actuator yangaphandle ngesiqu sevalve. Xa isebenza, iibhola ivalve flangeIsiqu siqhutywa ukuba sijikeleze ngomqheba, kwibhokisi yegiya okanye isixhobo sombane/somoya.

Iingenelo zokusebenzisa ishishini levalvu yebhola edityanisiweyo ngokupheleleyo:

1. Isakhiwo esithembekileyo kunye nokusebenza okuqinileyo kokutywinwa

Inkqubo yokuwelda iyonke isusa imingcipheko yokuvuza yoqhagamshelo lweflange yemveli kwaye ilungele iimeko zokusebenza ezirhabaxa ezinjengoxinzelelo oluphezulu, olunokutsha kunye neziqhushumbisi (umzekelo, uxinzelelo lwemibhobho yerhasi yendalo inokufikelela ngaphezulu kwe-10MPa). Izinto zokutywina zinxiba-resistant kwaye zinobomi benkonzo obungaphezulu kweminyaka eyi-10, ukunciphisa ukuphindaphinda kokugcinwa.

2. Ukuchasana nokuhamba okuphantsi kunye nokuhamba okupheleleyo

I-spherical ngokusebenzisa umngxuma ihambelana nobubanzi obungaphakathi bombhobho, kwaye ukuchasana kokuhamba kwe-medium yi-1/10 kuphela yepayipi yobude obufanayo, ukunciphisa ukusetyenziswa kwamandla. Ilungele uthutho oluhamba kakhulu (umzekelo, ububanzi bombhobho wombhobho we-oyile ekrwada unokufikelela kwi-1200mm).

3. Inganyangeki kumhlwa kwaye ilungelelaniswe nemekobume erhabaxa

Umzimba wevalvu yebhola engenastainless uqatywe ngentsimbi engatyiwayo okanye ngentsimbi yekhabhoni yokunqanda ukubola (efana neresin epoxy), enokumelana nokukhukuliseka komhlaba kunye nokukhukuliseka kwamanzi olwandle, kwaye ilungele iimeko ezintsonkothileyo ezinje ngaphantsi komhlaba nangaphantsi kwamanzi.

4. Kulula ukusebenza kunye neendleko eziphantsi zokugcinwa

Ukujikeleza i-90 ° kunokugqiba ukuvula nokuvala. Idityaniswe nenkqubo yolawulo oluzenzekelayo, ulawulo olukude lunokufumaneka. Izakhiwo ezidibeneyo zinciphisa iindawo ezihambayo, zinezinga eliphantsi lokungaphumeleli, kwaye umjikelo wokulondoloza unokwandiswa ukuya kwiminyaka engaphezu kwemihlanu.

Iimeko ezithile zosetyenziso lwevalve yebhola edityaniswe ngokupheleleyo:

Inkqubo yemibhobho yomgama omde

Ukuhanjiswa kwerhasi yendalo – esetyenziswa kwimizila yegesi yendalo elunxwemeni (efana noMbhobho werhasi weWest-East) kunye nemibhobho yokuhambisa igesi ekwinqanawa, inokumelana noxinzelelo oluphezulu kwaye iqinisekise ukutywinwa kwexesha elide ukuthintela iingozi zokhuseleko ezibangelwa kukuvuza kwerhasi yendalo.

I-oyile ekrwada / ukuthuthwa kwe-oyile esulungekisiweyo - Ukulawula ukuhamba kwecala eliphakathi kwimibhobho yeoli enqumla umda, uyilo olugcweleyo lunciphisa ukugcinwa kwe-oyile kunye nokuhla koxinzelelo, kunye nokuphucula ukuhamba kakuhle.

2. Igesi yasezidolophini kunye nothungelwano lwemibhobho yokufudumeza

Iyangcwatywa kwaye ifakwe kumbhobho werhasi oyintloko edolophini ukujongana nokuhlaliswa komhlaba kunye nokutshintsha kwamaqondo obushushu kunye nokunciphisa umngcipheko wokuvuza. Lawula ukuhamba kwamanzi ashushu kwinkqubo yokufudumala ephakathi, kwaye umelane noxinzelelo oluphezulu (1.6MPa) kunye nobushushu obuphezulu (120 ℃).

3. Indawo yoshishino

Umzi-mveliso wemichiza: Ukuthutha izinto ezonakalisayo ezifana neeasidi ezomeleleyo kunye neealkali ezinamandla. Izinto zensimbi ezingenasici kunye nezakhiwo zokutywina ezinzima zetsimbi ziqinisekisa ukhuseleko (njenge-hydrochloric acid kunye nemibhobho ye-caustic soda).

I-Metallurgy kunye namandla: Inokuphelisa ngokukhawuleza ukuhamba kwerhasi kwimibhobho yegesi eqhumayo okanye ilawule isantya sokuhamba kwimibhobho yamanzi okupholisa yezityalo zamandla obushushu, iqhelana nobushushu obuphezulu (ngaphezulu kwe-300℃) kunye neendawo ezinothuli.

4. Ubunjineli baseLwandle kunye neeNqanawa

Isetyenziswa kwimibhobho ye-oyile yeqonga elingaphesheya nolwandle kunye neenkqubo zamafutha enqanawe, ezikwaziyo ukumelana nokudleka kwamanzi olwandle kwaye zikwazi ukumelana nokungcangcazela kweenqanawa, kwaye ithobelana nemigangatho yamazwe ngamazwe efana ne-API 6D.

Ivalve yebhola edityanisiweyo ngokupheleleyo i-Pn16, enokuthembeka kwayo okuphezulu, iindleko zokugcinwa okuphantsi kunye nokuguquguquka okubanzi kwiimeko zokusebenza, ibe yinto engundoqo yokulawula ukuhanjiswa kwamandla, iinkqubo zefektri kunye nokwakhiwa kweziseko zophuhliso, ngokukodwa ezingenakutshintshwa kwiinkqubo ezinkulu zemibhobho ezifuna umsebenzi ozinzileyo wexesha elide.
