Mavavu a zipata wamba nthawi zambiri amatanthawuza ma valve otsekedwa mwamphamvu. Nkhaniyi ikufotokoza mwatsatanetsatane kusiyana pakati pa ma valve otsekedwa otsekedwa ndi ma valve wamba. Ngati mwakhutitsidwa ndi yankho, chonde perekani VTON chala chachikulu.
Mwachidule, ma valve otsekemera otsekemera otsekemera ndi zisindikizo pakati pa zitsulo ndi zopanda zitsulo, monga nylon \ tetrafluoroethylene, ndi ma valve otsekedwa mwamphamvu ndi zisindikizo pakati pa zitsulo ndi zitsulo;
Ma valve a zipata zofewa zofewa ndi ma valve otsekedwa mwamphamvu amatanthawuza zipangizo zosindikizira za mpando wa valve. Zisindikizo zolimba zimamangidwa ndendende ndi zida zapampando wa ma valve kuti zitsimikizire kulondola kofananira ndi pachimake cha valve (mpira), nthawi zambiri chitsulo chosapanga dzimbiri ndi mkuwa. Zisindikizo zofewa zimatanthawuza zida zosindikizira zomwe zili pampando wa valve ngati zida zopanda zitsulo. Chifukwa zida zosindikizira zofewa zimakhala ndi mphamvu zina, zofunikira pakuwongolera ndizocheperako kuposa zisindikizo zolimba. Timatchula za makhalidwe a VTON kufotokoza kusiyana pakati pa ma valve a zipata zofewa zofewa kunja ndi ma valve otsekedwa mwamphamvu.
1. Zida zosindikizira
1. Zida zosindikizira ziwirizi ndizosiyana.Ma valve otsekedwa ndi zipata zofewaNthawi zambiri amapangidwa ndi mphira kapena polytetrafluoroethylene. Ma valve otsekedwa mwamphamvu amapangidwa ndi zitsulo monga zitsulo zosapanga dzimbiri.
2. Chisindikizo chofewa: Chosindikiziracho chimapangidwa ndi zitsulo mbali imodzi ndi zotanuka zopanda zitsulo mbali inayo, zomwe zimatchedwa "soft seal". Chisindikizo chamtunduwu chimakhala ndi ntchito yabwino yosindikiza, koma sichilimbana ndi kutentha kwakukulu, zosavuta kuvala, komanso zimakhala ndi makina osowa. Mwachitsanzo: mphira wachitsulo; zitsulo tetrafluoroethylene, etc. Mwachitsanzo, kunja zotanuka mpando chisindikizochipata cha valvee wa VTON nthawi zambiri amagwiritsidwa ntchito pa kutentha kosakwana 100 ℃, ndipo amagwiritsidwa ntchito kwambiri kutentha madzi.
3. Chisindikizo cholimba: Chosindikiziracho chimapangidwa ndi zitsulo kapena zinthu zina zolimba kumbali zonse ziwiri, zomwe zimatchedwa "chisindikizo cholimba". Chisindikizo chamtunduwu chimakhala ndi kusasindikiza bwino, koma chimalimbana ndi kutentha kwambiri, kuvala komanso kukhala ndi makina abwino. Mwachitsanzo: zitsulo zachitsulo; chitsulo mkuwa; graphite yachitsulo; chitsulo aloyi chitsulo; (Chitsulo apa chingakhalenso chitsulo choponyedwa, chitsulo chosungunula, chitsulo cha alloy chikhozanso kukhala pamwamba, aloyi wopopera). Mwachitsanzo, valavu yachitsulo chosapanga dzimbiri ya VTON ingagwiritsidwe ntchito ngati nthunzi, gasi, mafuta ndi madzi, ndi zina zotero.
2. Ukadaulo wa zomangamanga
Chilengedwe cha ntchito yamakina ndizovuta, zambiri zomwe zimakhala zotsika kwambiri komanso zotsika kwambiri, zokhala ndi kukana kwakukulu komanso kuwononga kwakukulu kwapakati. Tsopano luso lamakono lakhala likuyenda bwino, kotero kuti ma valve a zipata otsekedwa mwamphamvu alimbikitsidwa kwambiri.
Ubale wa kuuma pakati pa zitsulo uyenera kuganiziridwa. Ndipotu, valve yotsekedwa mwamphamvu ndi yofanana ndi yotsekedwa yofewa chifukwa ndi chisindikizo pakati pa zitsulo. Thupi la valve liyenera kuumitsidwa, ndipo mbale ya valve ndi mpando wa valve ziyenera kukhala pansi mosalekeza kuti zisindikize. Njira yopangira ma valve otsekedwa mwamphamvu ndi yayitali.
3. Ntchito zikhalidwe
Kusindikiza zotsatira Zisindikizo zofewa zimatha kutulutsa ziro, pomwe zisindikizo zolimba zimatha kukhala zapamwamba kapena zotsika malinga ndi zofunikira;
Zisindikizo zofewa zimayenera kukhala zosawotcha, ndipo kutayikira kumachitika pakatentha kwambiri, pomwe zolimba sizingadutse. Zisindikizo zolimba za valve zotsekedwa mwadzidzidzi zingagwiritsidwe ntchito pansi pa kupanikizika kwakukulu, pamene zisindikizo zofewa sizingagwiritsidwe ntchito. Panthawiyi, valve ya VTON yotsekedwa mwamphamvu ndiyofunika.
Zisindikizo zofewa siziyenera kugwiritsidwa ntchito pazinthu zina zowononga, ndipo zisindikizo zolimba zingagwiritsidwe ntchito;
4. Mikhalidwe yogwirira ntchito
Zisindikizo zolimba zimatha kukhala zapamwamba kapena zotsika malinga ndi zofunikira; zisindikizo zofewa ziyenera kukhala zosawotcha, ndipo zosindikizira zofewa zimatha kukwaniritsa zisindikizo zapamwamba. Chifukwa pa kutentha kwambiri, zisindikizo zofewa zimatuluka, pamene zisindikizo zolimba sizikhala ndi vutoli; Zisindikizo zolimba zimatha kupirira kupsinjika kwakukulu, pomwe zosindikizira zofewa sizingathe. Mwachitsanzo, mavavu akunja opangidwa ndi chitsulo cha VTON amagwiritsa ntchito zisindikizo zolimba, ndipo kuthamanga kumatha kufika 32Mpa kapena 2500LB; zisindikizo zofewa sizingagwiritsidwe ntchito m'malo ena chifukwa cha kuyenda kwa sing'anga, monga zofalitsa zina zowonongeka); potsiriza, mavavu osindikizira olimba nthawi zambiri amakhala okwera mtengo kuposa zisindikizo zofewa. Ponena za zomangamanga, kusiyana pakati pa ziwirizi sikuli kwakukulu, kusiyana kwakukulu ndi mpando wa valve, chisindikizo chofewa sizitsulo, ndipo chisindikizo cholimba ndi chitsulo.
V. Kusankha zida
Kusankhidwa kwa chisindikizo chofewa ndi cholimbama valve pachipatamakamaka zochokera ndondomeko sing'anga, kutentha ndi kuthamanga. Nthawi zambiri, ngati sing'angayo ili ndi tinthu tating'onoting'ono kapena tavala kapena kutentha kumapitilira madigiri 200, ndi bwino kugwiritsa ntchito zisindikizo zolimba. Mwachitsanzo, nthunzi yotentha kwambiri nthawi zambiri imakhala mozungulira 180-350 ℃, kotero valavu yosindikizira yolimba iyenera kusankhidwa.
6. Kusiyana kwa mtengo ndi mtengo
Kwa caliber yomweyo, kukakamizidwa ndi zinthu, zotumizidwa kunja zosindikizidwa mwamphamvuma valve pachipatandi okwera mtengo kwambiri kuposa mavavu otsekedwa otsekedwa otsekedwa kunja; mwachitsanzo, VTON's DN100 yotulutsidwa kunja kwa valavu yachitsulo yachitsulo ndi 40% yokwera mtengo kuposa DN100 yotulutsidwa kunja kwazitsulo zofewa zosindikizidwa; ngati ma valve onse otsekedwa mwamphamvu ndi ma valve a zipata zofewa angagwiritsidwe ntchito pansi pazigawo zogwirira ntchito, poganizira za mtengo wake, yesetsani kusankha ma valve otsekedwa otsekedwa kunja.
7. Kusiyana kwa moyo wautumiki
Chisindikizo chofewa chimatanthawuza kuti mbali imodzi ya zisindikizozo ndi yopangidwa ndi zinthu zomwe zimakhala zolimba kwambiri. Nthawi zambiri, mpando wosindikizira wofewa umapangidwa ndi zinthu zopanda zitsulo zomwe zimakhala ndi mphamvu, kuuma komanso kutentha. Ili ndi ntchito yabwino yosindikiza ndipo imatha kutulutsa ziro, koma moyo wake komanso kusinthasintha kwake ndi kutentha ndizosauka. Zisindikizo zolimba zimapangidwa ndi chitsulo ndipo sizimasindikiza bwino, ngakhale opanga ena amati atha kutulutsa zero.
Ubwino wa zisindikizo zofewa ndikuchita bwino kusindikiza, ndipo choyipa chake ndi kukalamba kosavuta, kuvala ndi kung'ambika, komanso moyo waufupi wautumiki. Zisindikizo zolimba zimakhala ndi moyo wautali wautumiki, koma ntchito yawo yosindikiza imakhala yochepa poyerekeza ndi zisindikizo zofewa. Mitundu iwiriyi ya zidindo imatha kuthandizirana. Ponena za kusindikiza, zisindikizo zofewa zimakhala zabwinoko, koma tsopano kusindikizidwa kwa zisindikizo zolimba kungathenso kukwaniritsa zofunikira.
Zisindikizo zofewa sizingakwaniritse zofunikira zazinthu zina zowononga, koma zisindikizo zolimba zimatha kuthetsa vutoli!
Mitundu iwiriyi ya zisindikizo imatha kuthandizirana. Pankhani yosindikiza, zisindikizo zofewa zimakhala zabwinoko, koma tsopano kusindikizidwa kwa zisindikizo zolimba kungathenso kukwaniritsa zofunikira zomwezo!
Ubwino wa zisindikizo zofewa ndikuchita bwino kusindikiza, ndipo choyipa chake ndi kukalamba kosavuta, kuvala ndi kung'ambika, komanso moyo waufupi wautumiki.
Zisindikizo zolimba zimakhala ndi moyo wautali wautumiki, koma kusindikiza kumakhala koipitsitsa kuposa zisindikizo zofewa.
