Kodi ma check valves ndi magulu otani?

Monga chida chofunikira popewa kubweza kwapakati,fufuzani ma valveamagwiritsidwa ntchito kwambiri mumayendedwe a mapaipi. Malinga ndi mapangidwe osiyanasiyana ndi mfundo zogwirira ntchito, ma cheke ma valve amagawidwa m'magulu otsatirawa:

1. Swing valve chekeni valavu

Valavu yoyang'ana yozungulira imatsegula ndikutseka ndikuzungulira diski ya valve mozungulira axis yokhazikika. Pamene sing'anga ikuyenda patsogolo, valavu ya valve imakankhidwa motseguka; Pobwerera kumbuyo, valavu ya valve imatseka pansi pa kulemera kwake ndi mphamvu ya sing'angayo. Ubwino wake ndi kukana kwamadzi otsika, kutseguka kofulumira ndi kutseka, koyenera kwa mainchesi akulu, mawonekedwe otsika otsika monga ma pompu kapena mapaipi opingasa. Komabe, mphamvu ya nyundo yamadzi imatha kuchitika pakathamanga kwambiri, ndipo chipangizo cha buffer chimafunika.

2. Kwezani valavu yowunika

Disiki ya valve ya liftchekeni valavuimayenda motsatira mbali yoyima ya thupi la vavu. Pamene ikuyenda kutsogolo, kuthamanga kwapakati kumakankhira valavu ya valve; Pobwerera kumbuyo, chimbale cha valve chimagwera pansi pa mphamvu yokoka kapena mphamvu ya masika, kudula pakati. Valavu yamtunduwu imakhala ndi ntchito yabwino yosindikizira, koma kukana kuthamanga kwambiri, ndipo imagwiritsidwa ntchito kwambiri pamakina ang'onoang'ono, othamanga kwambiri, kapena oyika molunjika, monga machitidwe a nthunzi.

3. valavu ya gulugufe

Vavu yoyang'ana butterfly imaphatikiza mawonekedwe a ma valve ozungulira ndi agulugufe, okhala ndi chimbale chozungulira chomwe chimazungulira kuzungulira pakati. Ili ndi mawonekedwe ophatikizika komanso kulemera kopepuka, koyenera mapaipi akulu akulu ndi otsika, ndipo amagwiritsidwa ntchito kwambiri popereka madzi ndi uinjiniya wa ngalande. Koma kusindikizako kumakhala kochepa kwambiri ndipo kumafuna kukonza nthawi zonse.

4. valavu yoyang'ana diaphragm

Ma valve cheke a diaphragm amagwiritsa ntchito kusintha kwa zotanuka kwa ma diaphragms a rabara kuwongolera kutsegula ndi kutseka. Pamene sing'anga imayenda kutsogolo, diaphragm imatambasulidwa; Pobwerera m'mbuyo, diaphragm imabwereranso kuti itseke tchanelo. Valavu yamtundu uwu ilibe mikangano yamakina komanso moyo wautali wautumiki, koma kutentha kwake ndi kupanikizika kwake kumakhala kochepa, ndipo nthawi zambiri amagwiritsidwa ntchito poyeretsa ma TV kapena machitidwe otsika kwambiri.

5. Piston chekeni valavu

Vavu yoyang'ana pisitoni imatsegula ndikutseka kudzera mu mgwirizano wa pisitoni ndi masika. Kuthamanga kwapakati kumagonjetsa mphamvu ya masika kukankhira pisitoni kuti isunthe, ndipo kasupe amabwerera ndikutseka pamene akubwerera. Ili ndi ntchito yabwino yosindikiza ndipo ndiyoyenera kutentha kwambiri komanso malo othamanga kwambiri, monga mafakitale a petrochemical, koma mawonekedwe ake ndi ovuta komanso mtengo wake ndi wokwera.

Zochitika zogwiritsidwa ntchito zamitundu yosiyanasiyana yafufuzani ma valveziyenera kusankhidwa momveka bwino potengera mawonekedwe a sing'anga, kupanikizika, kuthamanga kwa magazi, komanso kuyika zinthu kuti zitsimikizire kuti dongosololi likuyenda bwino komanso moyenera.
