Ubuso bwo gufunga bwa valve bukunze kwangirika, kwangirika no kwangirika n'icyo gikoresho, bityo ni igice cyoroshye kwangirika kuri valve. Nk'imashini ikoresha umwuka n'imashini ikoresha amashanyarazi n'izindi mashini zikoresha amashanyarazi, bitewe no gufungura no gufunga kenshi kandi vuba, ubwiza bwazo n'ubuzima bwazo bigira ingaruka ku buryo butaziguye. Icy'ingenzi ku buso bwo gufunga valve ni uko mashini ishobora gufunga neza kandi yizewe mu gihe cy'akazi kagenwe. Kubwibyo, ibikoresho by'ubuso bigomba kugira ibi bikurikira:
(1) Imikorere myiza yo gufunga, ni ukuvuga ko ubuso bwo gufunga bugomba kuba bushobora gukumira amazi y'ubucukuzi;
(2) Ifite imbaraga runaka, ubuso bwo gufunga bugomba kuba bushobora kwihanganira igitutu cyihariye cy’igitutu gikozwe n’itandukaniro ry’igitutu giciriritse;
(3) Ubudahangarwa n'ingese, bitewe n'igihe kirekire cy'ubudahangarwa n'ubudahangarwa, ubuso bugomba kuba bufite ubudahangarwa bukomeye n'ubudahangarwa bujyanye n'ibisabwa mu gishushanyo;
(4) Ubushobozi bwo kwirinda gushwanyagurika, gufunga valve byose ni dynamic seal, kandi hari ukutumvikana hagati yo gufunga mu gihe cyo gufungura no gufunga;
(5) Ubudahangarwa bw'isuri, ubuso bufunga bugomba kuba bushobora kurwanya isuri y'ibinyabiziga byihuta cyane no gukubitana kw'uduce duto;
(6) Ubushyuhe buhamye neza, ubuso bwo gufunga bugomba kugira imbaraga zihagije no kudakoresha ogisijeni ku bushyuhe bwinshi, kandi bugomba kugira ubushobozi bwo kudakoresha ubukonje ku bushyuhe buke;
(7) Imikorere myiza yo gutunganya, byoroshye gukora no kubungabunga, valve ikoreshwa nk'igice cy'ingenzi muri rusange, kandi yizewe ko izagira agaciro gakomeye.
Imikoreshereze n'amahame yo guhitamo ibikoresho byo gufunga ubuso bw'amavali. Ibikoresho byo gufunga ubuso bigabanyijemo ibice bibiri: icyuma n'ibitari icyuma. Imikoreshereze ikoreshwa ku bikoresho bikunze gukoreshwa ni iyi ikurikira:
(1) Rubber. Muri rusange ikoreshwa mu gufunga amavali yo mu irembo afite umuvuduko muto, amavali yo mu gitereko, amavali y'ibinyugunyugu, amavali yo kugenzura n'andi mavali.
(2) Plasitike. Plasitike zikoreshwa mu gufunga ubuso ni nylon na PTFE, zifite imiterere yo kudakira neza ingese ndetse n'ubushobozi buke bwo gushwanyagurika.
(3) Babbitt. Izwi kandi nka alloy bearing, ifite ubushobozi bwo kurwanya ingese kandi ishobora kwinjira neza. Ikwiriye gufunga ubuso bwa valve ifunga ammonia ifite umuvuduko muto n'ubushyuhe bwa -70-150℃.
(4) Ifu y'umuringa. Ifite ubushobozi bwo kwangirika neza kandi irwanya ubushyuhe. Ikwiriye ifu y'umubumbe, ifu y'icyuma gikozwe mu cyuma ...
(5) Icyuma kidashonga cya Chrome-nickel. Gifite ubushobozi bwo kurwanya ingese, kurwanya isuri no kurwanya ubushyuhe. Kibereye ahantu nk'aside nitrike ishyushye.
(6) Icyuma kidashonga cya Chrome. Gifite ubushobozi bwo kurwanya ingese kandi gikoreshwa mu mavali afite umuvuduko mwinshi n'ubushyuhe butarenze 450 ℃ ku mavuta, umwuka w'amazi n'ibindi bikoresho.
(7) Icyuma gifite chromium nyinshi. Gifite ubushobozi bwo kurwanya ingese no gukomera mu kazi, kandi gikwiriye gukoreshwa mu mavuta ashyushye cyane, amavuta ashyushye cyane, umwuka n'ibindi bikoresho.
(8) Icyuma gikozwe muri nitride. Gifite ubushobozi bwo kurwanya ingese no gushwanyagurika, kandi gikunze gukoreshwa mu mavali y’irembo ry’imashini zikoresha ubushyuhe. Iki gikoresho gishobora kandi gutoranywa mu rwego rwo gukoresha amavali y’umupira afunze neza.
(9) Karubide. Ifite imiterere myiza nko kurwanya ingese, kurwanya isuri no kurwanya gushwanyagurika, kandi imara igihe kirekire. Ni ibikoresho byiza byo gufunga. Ama-electrode akoreshwa cyane yo gucukura tungsten drill alloy na drill base alloy surface, n'ibindi, ashobora gukora ubuso bufunga umuvuduko mwinshi cyane, bushyuha cyane, bukwiriye peteroli, peteroli, gaze, hydrogen n'ibindi.
(10) Aloyi yo gusudira ikoresheje spray. Hari aloyi zishingiye kuri cobalt, aloyi zishingiye kuri nikeli, n'aloyi zishingiye ku gasaya, zifite ubushobozi bwo kurwanya ingese no kwangirika neza.
Kugira ngo hamenyekane umutekano n'ubwizerwe bw'ikimenyetso cy'ingufu, ibikoresho byatoranijwe bigomba kugenwa hakurikijwe imiterere yihariye y'akazi. Niba icyuma gikoresha amashanyarazi menshi, mu guhitamo ibikoresho, kigomba kuba cyujuje imikorere ya amashanyarazi mbere na mbere, hanyuma kigakurikiza ibisabwa n'indi miterere; Ikimenyetso cy'ingufu y'irembo kigomba kwitondera imikorere myiza yo gushwanyaguza; Vali z'umutekano, vali zo kugosora na vali igenzura byoroshye kwangirika n'icyuma, kandi ibikoresho bifite ubwiza bwo kwangirika bigomba gutoranywa; Ku miterere y'impeta yo gufunga n'umubiri, ibikoresho bifite ubwiza bwinshi bigomba gufatwa nk'ubuso bwo gufunga; Vali rusange zifite ubushyuhe buke n'umuvuduko muto zigomba guhitamo rubber na plastike bifite imikorere myiza yo gufunga nk'ikimenyetso; Mu guhitamo ibikoresho byo gufunga, ni ngombwa kumenya ko ubwiza bw'ubuso bw'intebe ya vali bugomba kuba burebure kuruta ubw'ubuso bwo gufunga bwa disiki ya vali.
