Chidule
Valavu yowongolera ndi gawo lowongolera mu dongosolo lotumizira madzi, lomwe lili ndi ntchito zodula, kulamulira, kusinthasintha, kupewa kubwerera kwa madzi, kukhazikika kwa magetsi, kusinthasintha kapena kusefukira kwa madzi komanso kuchepetsa kuthamanga kwa madzi. Mavavu owongolera mafakitale amagwiritsidwa ntchito makamaka powongolera njira mu zida zamafakitale ndipo ndi a mafakitale a zida, zida ndi makina.
1. Valavu yowongolera ndi yofanana ndi mkono wa loboti pochita zinthu zodziyimira pawokha zamafakitale, ndipo ndiye chinthu chomaliza chowongolera kusintha magawo azinthu monga kuyenda kwapakati, kuthamanga, kutentha, ndi mulingo wamadzimadzi. Chifukwa imagwiritsidwa ntchito ngati chowongolera chakumapeto mu dongosolo lowongolera njira zodziyimira pawokha zamafakitale, valavu yowongolera, yomwe imadziwikanso kuti "chowongolera", ndi imodzi mwazipangizo zofunika kwambiri popanga zinthu mwanzeru.
2. Valavu yowongolera ndiye gawo lofunikira kwambiri pa automation yamafakitale. Mulingo wake wa chitukuko chaukadaulo umasonyeza mwachindunji mphamvu zoyambira zopangira zida mdziko muno komanso mulingo wamakono wamafakitale. Ndikofunikira kuti makampani oyambira ndi mafakitale ake ogwiritsira ntchito azitha kupeza nzeru, maukonde ndi ma automation. Mavavu owongolera nthawi zambiri amapangidwa ndi ma actuator ndi ma vavu, omwe amatha kugawidwa malinga ndi ntchito, mawonekedwe a sitiroko, mphamvu yomwe imagwiritsidwa ntchito ndi actuator yokhala ndi zida, kuchuluka kwa kuthamanga, ndi kutentha.
Unyolo wa mafakitale
Makampani opanga ma valve owongolera omwe ali pamwamba pake ndi chitsulo, zinthu zamagetsi, zinthu zosiyanasiyana zoyeretsera, zomangira, zomangira ndi zipangizo zina zopangira mafakitale. Pali makampani ambiri opanga ma valve owongolera, mpikisano wokwanira komanso kupezeka kokwanira, zomwe zimapangitsa kuti pakhale maziko abwino opangira ma valve owongolera; Mitundu yosiyanasiyana ya ntchito zoyambira, kuphatikizapo mafuta, petrochemical, mankhwala, mapepala, kuteteza chilengedwe, mphamvu, migodi, zitsulo, mankhwala ndi mafakitale ena.
Kuchokera pamalingaliro a kugawa ndalama zopangira:
Zipangizo zopangira monga chitsulo, zinthu zamagetsi ndi zinthu zopangira zinthu zotayidwa zimaposa 80%, ndipo ndalama zopangira zimakhala pafupifupi 5%.
Gawo lalikulu kwambiri logwiritsira ntchito ma valve owongolera ku China ndi makampani opanga mankhwala, omwe ali ndi zoposa 45%, kutsatiridwa ndi mafakitale amafuta ndi gasi ndi magetsi, omwe ali ndi zoposa 15%.
Ndi kukwezedwa kwa ukadaulo wowongolera mafakitale m'zaka zaposachedwa, kugwiritsa ntchito ma valve owongolera popanga mapepala, kuteteza chilengedwe, chakudya, mankhwala ndi madera ena kukukulanso mwachangu komanso mwachangu.
Kukula kwa makampani
Kukula kwa mafakitale ku China kukupitirirabe kukula, ndipo mulingo wa makina oyendetsera mafakitale ukupitirirabe kukula. Mu 2021, mtengo wowonjezera wa mafakitale ku China udzafika pa 37.26 trillion yuan, ndi kukula kwa 19.1%. Monga gawo lowongolera la makina oyendetsera mafakitale, kugwiritsa ntchito valavu yowongolera mafakitale mumakina owongolera mafakitale kumathandizira kukhazikika, kulondola komanso kudziyimira pawokha kwa makina owongolera. Malinga ndi deta ya Shanghai Instrument Industry Association: mu 2021, chiwerengero cha mabizinesi owongolera makina oyendetsera mafakitale ku China chidzawonjezeka kufika pa 1,868, ndi ndalama zokwana 368.54 biliyoni yuan, kuwonjezeka kwa chaka ndi chaka kwa 30.2%. M'zaka zaposachedwa, kutulutsa kwa mavalavu owongolera mafakitale ku China kwawonjezeka chaka ndi chaka, kuchokera pa ma seti 9.02 miliyoni mu 2015 kufika pa ma seti pafupifupi 17.5 miliyoni mu 2021, ndi kuchuluka kwa pachaka kwa 6.6%. China yakhala imodzi mwa opanga mavalavu owongolera mafakitale akuluakulu padziko lonse lapansi.
Kufunika kwa ma valve owongolera mafakitale m'mafakitale otsatira monga mankhwala, mafuta ndi gasi kukupitirirabe kukula, makamaka kuphatikiza mbali zinayi: mapulojekiti atsopano ogulira ndalama, kusintha kwaukadaulo kwa mapulojekiti omwe alipo, kusintha zida zosinthira, ndi ntchito zowunikira ndi kukonza. M'zaka zaposachedwa, dzikolo lasintha kapangidwe ka mafakitale ndikusintha chuma. Kukula kwa njira komanso kulimbikitsa mwamphamvu njira zosungira mphamvu ndi kuchepetsa utsi kwakhala ndi zotsatira zodziwikiratu pakukweza ndalama za polojekitiyi komanso zosowa zaukadaulo zamafakitale otsatira. Kuphatikiza apo, kusintha kwabwinobwino ndikusintha zida ndi ntchito zowunikira ndi kukonza kwabweretsanso kufunikira kokhazikika kwa chitukuko cha makampani. Mu 2021, kukula kwa msika wa ma valve owongolera mafakitale ku China kudzakhala pafupifupi 39.26 biliyoni yuan, kuwonjezeka kwa chaka ndi chaka kwa oposa 18%. Makampaniwa ali ndi phindu lalikulu komanso phindu lalikulu.
Kapangidwe ka bizinesi
Mpikisano wa msika wa ma valve olamulira mafakitale mdziko langa ukhoza kugawidwa m'magawo atatu,
Mu msika wotsika mtengo, makampani akunyumba akwanitsa kukwaniritsa zosowa za msika mokwanira, mpikisano ndi waukulu, ndipo kufanana kwake n'koopsa;
Mu msika wapakati, mabizinesi am'nyumba omwe ali ndi luso lapamwamba kwambiri akuimiridwa ndiTianjin Tanggu Madzi-chisindikizo VavuCo., Ltdkutenga gawo la msika;
Mu msika wapamwamba: kuchuluka kwa malonda a m'dziko muno kuli kochepa, komwe kwenikweni kumakhala makampani akunja oyamba komanso makampani aukadaulo.
Pakadali pano, opanga ma valve onse olamulira m'nyumba apeza satifiketi ya ISO9001 quality system ndi laisensi yopangira zida zapadera (pressure pipeline) TSG, ndipo opanga ena adutsa satifiketi ya API ndi CE, ndipo amatha kutsatira miyezo ya ANSI, API, BS, JIS ndi miyezo ina. Kupanga ndi kupanga zinthu.
Malo akuluakulu amsika wa ma valve owongolera dziko langa akoka mitundu yambiri yakunja kuti ilowe mumsika wamkati. Chifukwa cha mphamvu zachuma, ndalama zambiri zaukadaulo komanso luso lochuluka, mitundu yakunja ili pamalo otsogola pamsika wa ma valve owongolera, makamaka msika wapamwamba wa ma valve owongolera.
Pakadali pano, pali opanga mavavu owongolera m'nyumba ambiri, omwe nthawi zambiri amakhala ochepa komanso ochepa m'mafakitale, ndipo pali kusiyana kwakukulu pakati pa opikisana nawo akunja. Ndi kupita patsogolo kwa ukadaulo wa mavavu owongolera m'nyumba, chizolowezi cholowetsa zinthu zapamwamba kuchokera kunja sichingasinthe.
Dchitukuko chamakono
Vavu yowongolera mafakitale m'dziko langa ili ndi njira zitatu zotsatirazi:
1. Kudalirika kwa zinthu ndi kulondola kwa kusintha kudzawonjezeka
2. Kuchuluka kwa zinthu zomwe zimapezeka m'malo osiyanasiyana kudzawonjezeka, ndipo kusintha zinthu kuchokera kunja kudzawonjezeka, ndipo kuchuluka kwa zinthu zomwe zimagulitsidwa m'mafakitale kudzawonjezeka.
3. Ukadaulo wa mafakitale nthawi zambiri umakhala wofanana, wopangidwa modular, wanzeru, wogwirizana komanso wolumikizidwa ndi maukonde
