Malingana ndi zochitika zosiyanasiyana zogwiritsira ntchito ndi zosowa, zisindikizo za valve pampu zimatha kugawidwa m'mitundu yambiri, makamaka kuphatikizapo: chisindikizo cha makina, chisindikizo chonyamula, chisindikizo cha gasi ndi chisindikizo chamadzimadzi.Mtundu uliwonse wa chisindikizo uli ndi mawonekedwe ake apadera komanso mawonekedwe ake ogwiritsira ntchito.
1, chisindikizo chamakina: chisindikizo cha makina ndi chosindikizira chodziwika bwino cha pampu, chimakhala cholondola kwambiri, champhamvu kwambiri, kukana kuvala kwambiri ndi zabwino zina, zoyenera kusinthasintha kothamanga komanso nthawi yosindikiza.Chisindikizo chomakina chimatengera mawonekedwe a ma ring friction pair, ndipo nkhope zomalizira za mphete zosunthika komanso zokhazikika zimakhala zolumikizana ndipo zimakhala ndi mikangano yotsetsereka, yomwe imatha kutulutsa zero.Zisindikizo zamakina zimakhala ndi moyo wautali wautumiki komanso ndalama zochepa zosamalira.
2, kunyamula chisindikizo: chisindikizo chonyamulira ndi chosindikizira chosavuta chapampu, chili ndi ubwino wamapangidwe osavuta, kukonza kosavuta, koyenera kupanikizika ndi mlengalenga kapena nthawi yotsika yosindikiza.Chisindikizo chonyamuliracho chimapangidwa ndi zinthu zofewa zonyamula katundu, monga asbestos fiber, graphite, ndi zina zotero, zomwe zimapanikizidwa ndikumangirizidwa mwamphamvu ku mbali zamkati za mpope kapena valve kuti zitheke kusindikiza.Mtengo wa kulongedza chisindikizo ndi wotsika mtengo, ndipo ndi woyenera pazochitika zina zosafunika kwenikweni.
3, chisindikizo chamadzimadzi cha gasi: chisindikizo chamadzimadzi cha gasi ndi chosindikizira chapadera chapampu, chimatha kuletsa kutayikira kwa gasi kapena media zamadzimadzi.Chisindikizo chamadzimadzi chimatenga mapangidwe apadera, omwe amatha kusunga mphamvu ya gasi kapena sing'anga yamadzimadzi mkati mwamtundu wina, kuti akwaniritse kusindikiza.Gas seal liquid seal ndiyoyenera kugwiritsa ntchito zochitika zina zapadera monga zoyaka ndi kuphulika, zoopsa komanso zoopsa.
