Ona Mufananidzo Mukuru
Valve ndiyo imwe yemidziyo yakakosha mune fluid control system.Parizvino, mashandisirwo makuru evharuvhu anosanganisira peturu uye gasi, simba, makemikari engineering, mvura uye kurapa kwetsvina, kugadzira mapepa uye simbi.Pakati pazvo, mafuta & gasi, simba uye indasitiri yemakemikari ndiyo inonyanya kukosha mashandisirwo evharuvhu.Maererano nekufanotaura kubva kuMcIlvaine, mutarisiri wemusika, kudiwa kwevharuvhu yeindasitiri kuchasvika madhora mabhiriyoni zana. Kudiwa kwesimba munyika dzichiri kusimukira ndicho chinhu chikuru chekusimudzira musika wevharuvhu weindasitiri kusimudzira.Zvinofungidzirwa kuti kubva 2015 kusvika 2017, kukura kweiyo indasitiri yevharuvhu musika saizi icharamba ichisvika 7%, yakakwira zvakanyanya kupfuura mwero wekukura kweindasitiri yemaindasitiri evharuvhu.
Valve chinhu chekutonga cheiyo fluid transmission system, ine mabasa ekucheka-kubvisa, kugadzirisa, rwizi diversion, countercurrent kudzivirira, voltage kudzikamisa, shunt kana mafashama uye decompression.Vhuru yakarongedzerwa muindasitiri yekudzora vharafu uye vharuvhu yevagari.Industrial valve inoshandiswa kudzora kuyerera kwe media, kudzvanywa, tembiricha, chiteshi chemvura uye mamwe ma parameter ehunyanzvi.Zvichienderana nezviyero zvakasiyana, vharafu yeindasitiri inogona kuiswa mumhando dzakasiyana.Kune marudzi emitemo, vharafu inorongedzerwa kuita mutemo, kucheka, kudzora uye kucheka;maererano nemidziyo yevhavha, vharafu inoiswa musimbi, isiri-simbi uye simbi liner;zvichibva pakutyaira modhi, vharafu yeindasitiri inoiswa mumhando yemagetsi, pneumatic type, hydraulic type uye manual type;zvichienderana nekupisa, vharafu inoiswa mu ultralow tembiricha vharafu, yakaderera tembiricha vharafu, yakajairika tembiricha vharafu, yepakati tembiricha vharafu uye yakakwirira tembiricha vharafu uye vharafu inogona kuiswa muvacuum vharafu, yakaderera pressure vharafu, yepakati pressure vharafu, high pressure valve uye Ultra. high pressure valve.
Chinese valve indasitiri yakatanga kubva kuma1960.Gore ra1980 risati rasvika, China yaingokwanisa kugadzira zvikamu zvinopfuura mazana matanhatu uye mativi mazana maviri nemazana manomwe ezvigadzirwa zvevharuvhu, kushaya kugona kugadzira vharafu ine maparamita akakwira uye zvehunyanzvi zvemukati.Kuzadzisa kudiwa kwevhavha ine yakakwirira paramita uye yakakwirira tekinoroji yemukati inokonzerwa neindasitiri uye kurima muChina kuri kusimukira zvakanyanya, kubvira 1980's.China yakatanga kushandisa pfungwa ichibatanidza budiriro yakazvimiririra uye kusuma tekinoroji kugadzira matekinoroji evharuvhu.Mamwe mabhizinesi akakosha evharuvhu anosimudzira tsvakiridzo yetekinoroji nekusimudzira, achisimudza mafambiro epamusoro ekupinza tekinoroji tekinoroji.Parizvino, China yakatogadzira gedhi vharafu, globe vharafu, throttle vharafu, bhora vharafu, butterfly vharafu, diaphragm vhara, plug vharafu, cheki vharafu, kuchengetedza vharafu, kuderedza vharafu, drain vharafu uye mamwe vharafu, kusanganisira gumi nemaviri, anopfuura 3,000. mhando uye 40,000 zviyero.
Zvinoenderana neiyo statics yeValve World, kudiwa kwemusika wepasi rose kwevhavhavha yeindasitiri ine kuchera, chekufambisa uye petrifaction.Oiri & gasi ine chikamu chepamusoro, inosvika 37.40%.Kudiwa kwesimba nemakemikari engineering kunotevera, zvichiteerana accounting ye21.30% uye 11.50% yepasi rose maindasitiri evharuvhu kudiwa kwemusika.Kudiwa kwemusika mumatatu ekutanga ekushandisa maakaundi e70.20% yehuwandu hwemusika kudiwa.MuChina, mainjiniya emakemikari, simba nemafuta & gasi ndiwo zvakare musika mukuru wekutengesa wevhavha.Kudiwa kwevharuvhu zvichienderana ne25.70%, 20.10% uye 14.70% yezvese zvinodiwa.Nhamba yekuda inoverengera 60.50% yehuwandu hwevhavha inodiwa.
Panyaya yekuda kwemusika, kudiwa kwevharuvhu munzvimbo yekuchengetedza mvura uye hydropower, simba renyukireya uye indasitiri yemafuta gasi inochengetedza maitiro akasimba mune ramangwana.
Mukuchengetedza mvura uye simba remvura, zano rakapihwa neGeneral Office yeState Council rinoratidza kuti panosvika 2020, huwandu hwemagetsi emagetsi emvura anofanirwa kusvika pamamiriyoni mazana matatu nemakumi mashanu emakiromita.Kukura kwe hydropower kunokonzeresa kudiwa kukuru kwevharuvhu.Kugara kuri kukura kwekudyara pamagetsi emvura kunosimudzira budiriro muvharuvhu yeindasitiri.
