Kutentha Kwachigawo Kutenthetsa Kwambiri Mpira Vavu

Kufotokozera Mwachidule:

Chigawo chotenthetsera chotenthetsera valavu chotenthetsera m'matauni chimakhala ndi mawonekedwe otsekedwa mwamphamvu, osataya kutayikira, kudalirika kwakukulu komanso moyo wautali wautumiki, womwe umagwiritsidwa ntchito kwambiri m'matauni omwe amakwiriridwa mwachindunji mapaipi amadzi otentha.Chifukwa valavu thupi zinthu zofanana ndi chitoliro zinthu, sipadzakhala kupsyinjika osagwirizana, ndipo palibe mapindikidwe chifukwa chivomezi ndi magalimoto kudutsa pansi, ndi payipi kugonjetsedwa ndi ukalamba.

Chigawo chotenthetsera chotenthetsera valavu chotenthetsera m'matauni chimakhala ndi mawonekedwe otsekedwa mwamphamvu, osataya kutayikira, kudalirika kwakukulu komanso moyo wautali wautumiki, womwe umagwiritsidwa ntchito kwambiri m'matauni omwe amakwiriridwa mwachindunji mapaipi amadzi otentha.Chifukwa valavu thupi zinthu zofanana ndi chitoliro zinthu, sipadzakhala kupsyinjika osagwirizana, ndipo palibe mapindikidwe chifukwa chivomezi ndi magalimoto kudutsa pansi, ndi payipi kugonjetsedwa ndi ukalamba.

Monga gawo lotseguka / lotsekeka, thupi limapangidwa ndi chitoliro chachitsulo kapena mbale.Ili ndi zoyandama zoyandama komanso zokhazikika, mawonekedwe ampando wa valve amakhala ndi pisitoni ndipo amavala zolipira.Chosindikiziracho chimapangidwa ngati chisindikizo chimodzi kapena chisindikizo chapawiri (mphete yofewa yokhala pansi ndi zitsulo zokhala pansi), masika adzaonetsetsa kuti mphete yosindikizira pa mpira, ndipo valavu ikhoza kukhalabe yopanda kutayikira mwamphamvu ndikuyendetsa ntchito yokhazikika kwa nthawi yayitali ngakhale kupanikizika sikukhazikika.Valve ya mpira imakhala ndi ubwino wa voliyumu yaying'ono, kulemera kwake, kusindikiza popanda kutaya, kusungirako kwaulere, moyo wautali wautumiki, ntchito yosavuta ndi zina zotero.

Makhalidwe Antchito

1.Full bore ndi Kuchepetsa kapangidwe ka bore;

2.Easy & mwamsanga kutsegula & kutseka
Mtundu uwu wa valavu ya mpira umangofunika kutembenuza mpirawo (chotsegula / chotseka) 90 °, chomwe chiri chosavuta komanso chofulumira kugwira ntchito.

3.Good chisindikizo ntchito
Mpando wa valavu yowotcherera bwino nthawi zambiri umapangidwa ndi zinthu zotanuka monga PTFE, ndi zina zotero, zosindikizidwa ndi zitsulo zachitsulo, zomwe zimatchedwa kuti zofewa zomwe zimatha kutsimikizira kuti chisindikizo chikugwira ntchito.

4.Thupi la valve limapangidwa ndi chitoliro chachitsulo chosasunthika kapena chopangidwa ndi mawonekedwe opangira kuwotcherera a mbale yopukutira;

5.Kuzungulira kwa moyo wautali
Chifukwa cha kudzipaka bwino kwa PTFE, kukangana ndi kuvala ndi mpira kumakhala kochepa, ndipo roughness imachepetsedwa ndi kusintha kwa kayendedwe ka valve ya mpira, kotero kuti moyo wautumiki wa valavu ya mpira ukuwonjezeka.

6.Kudalirika kwakukulu
Valavu yowotcherera bwino imakhala yodalirika kwambiri, makamaka chifukwa:
a) mpando wa valve wa zinthu za PTFE uli ndi kudzipaka bwino, kukangana kakang'ono ndi kuvala ndi mpira, kusakhala ndi abrasion ndi kuvala lakuthwa;
b) Tsinde limayikidwa mkati, motero limapewa ngozi yomwe imabwera chifukwa cha tsinde lophulitsidwa chifukwa chotheka kumasuka kwa chithokomiro chifukwa cha kuthamanga kwamadzi.

7.Anti-blowout Tsinde blowproof, angapo wosanjikiza kusindikiza tsinde;

8.Mpira uli ndi mitundu iwiri ya trunnion wokwera ndikuyandama;

9.Mpando wa valve kawiri, wosanjikiza umodzi kapena mphete yachiwiri yosindikizira yofewa ndi zitsulo zosindikizira zitsulo zimapanga zisindikizo zingapo zosanjikiza;

10.Cavity kudzithandiza pansi pa kupsyinjika;

11.Double block and bleed (DBB) kapangidwe (Ngati pakufunika);

12.Flexible lotseguka / kutseka, yosavuta kugwiritsa ntchito.

13.Kusamalira kwaulere
Valavu iyi ya mpira imakhala ndi mawonekedwe osakonza.
