Ndi mavavu ati omwe angagwiritsidwe ntchito poyang'anira mtundu wa gasi wanzeru ma meter owongolera magetsi

valavu Control, valavu mpira, valavu butterfly, valavu pachipata angagwiritsidwe ntchito kulamulira valavu mpweya, ndi mmene kulamulira mpweya, zotsatirazi ndi mndandanda waung'ono wa chidziwitso mwatsatanetsatane, kuphatikizapo makhalidwe structural ndi mfundo ntchito za ulamuliro mpweya valavu. .
Woyang'anira
Vavu yowongolera imagwiritsidwa ntchito kwambiri m'mafakitale a chinthu chowongolera. Valve yowongolera imapangidwa ndi chiwalo chachikulu ndi valavu. Malinga ndi ziwalo zosiyanasiyana zoyang'anira, zitha kugawidwa kukhala valavu yowongolera pneumatic, valavu yowongolera magetsi komanso valavu yodzilamulira yokha. Kuwongolera valavu povomereza makina opangira mafakitale 4-20MA chizindikiro chowongolera kuti akwaniritse kuwongolera ndi kuwongolera mpweya.
Valve ya mpira
Vavu ya mpira ndi imodzi mwa ma valve omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi, komanso m'zaka khumi zapitazi kukula kwachangu kwa valve. Amagwiritsidwa ntchito kwambiri podula, kuwongolera ndi kugawa m'mapaipi. Ndi valavu multifunctional ntchito kwambiri kulamulira gasi. Valve ya mpira imangofunika spool kuti izungulire 90¡ã kuti amalize kutsegulira ndi kutseka ndikudula mwachangu gawo la sing'anga.
Valve ya butterfly
Valavu ya butterfly ndi yotsika mtengo, kapangidwe kosavuta ka valve, kotero valavu yagulugufe ndi yoyenera kwambiri pamlingo waukulu. Vavu ya butterfly imadziwika ndi mphamvu yothamanga kwambiri komanso kukana kwamadzimadzi pang'ono. Malingana ngati mbale ya butterfly ifika ku 90¡ã, ikhoza kutsegulidwa ndi kutsekedwa kamodzi, kuti mukwaniritse kusintha kwapaipi ndi kudula ndi kuwongolera gasi.
Ma valve a zipata
Vavu yachipata imakhala ndi thupi la valve, mpando, tsinde, chipata, chivundikiro cha valve, mphete yosindikiza ndi zina. Ubwino wa valavu yachipata ndi mawonekedwe ophatikizika, kukana kwamadzi pang'ono, moyo wautali wautumiki, kudzera mu mbale ya valve mmwamba ndi pansi kuyenda kuti mukwaniritse kutsegula kwa valve ndi kuwongolera mpweya, pamene valavu yachipata yatsekedwa, kusindikiza pamwamba kumadalira kuthamanga kwapakati. malo osindikizira a mbale ya pachipata kumbali ina ya mpando wa valve kuti atsimikizire kusindikiza pamwamba pa malo osindikizira.
Meta yamadzi yanzeru ndi mtundu watsopano wa mita yamadzi yomwe imagwiritsa ntchito ukadaulo wamakono wa microelectronics, ukadaulo wamakono wozindikira komanso ukadaulo wanzeru wamakhadi a IC kuyeza kugwiritsa ntchito madzi ndikusamutsa deta yogwiritsira ntchito madzi ndikukhazikitsa zochitika. Pakali pano, mitundu ikuluikulu ya mavavu am'madzi am'madzi am'madzi apakompyuta ndi valavu ya mpira, valavu ya ceramic ndi valavu ya diaphragm.
Meta yamadzi yanzeru ndi mtundu watsopano wa mita yamadzi yomwe imagwiritsa ntchito ukadaulo wamakono wamagetsi ang'onoang'ono, ukadaulo wamakono wozindikira komanso ukadaulo wanzeru wamakhadi a IC kuyeza kugwiritsa ntchito madzi ndikusamutsa deta yogwiritsira ntchito madzi ndikukhazikitsa zochitika. Pakali pano, mitundu ikuluikulu ya mavavu am'madzi am'madzi am'madzi apakompyuta ndi valavu ya mpira, valavu ya ceramic ndi valavu ya diaphragm.
Mtundu wa valavu yowongolera magetsi ya mita yanzeru yamadzi
(1) valavu ya mpira
Vavu ya mpira chifukwa cha zofunikira za torque yoyendetsa, chifukwa cha kukula kapena kuvala kogwiritsidwa ntchito, ndikosavuta kutayikira, kulephera kusinthana ndi zovuta zina, mita yamadzi yanzeru yapakhomo yogwiritsa ntchito mavavu otere kwambiri, pogwiritsa ntchito zovuta zambiri.
(2) valavu ya ceramic
Valve ya ceramic imakhala ndi moyo wautali wautumiki, kudalirika kwakukulu kosinthira, kutsika pang'ono, ndipo sikophweka kugwiritsa ntchito. Chifukwa ndi mankhwala a patent, opanga mita yamadzi anzeru am'nyumba amagwiritsa ntchito valavuyi ndi ochepa komanso apakati.
(3) valavu ya diaphragm
Ma valve a diaphragm sagwiritsidwa ntchito kawirikawiri ndi opanga chifukwa cha mtengo wawo wokwera. Valve yanzeru yamadzi yamadzi ndiyonso index yofunikira kwambiri yogwiritsidwa ntchito.
Chifukwa cha khalidwe la madzi a makina a chitoliro, kuwonongeka kwa valavu ya mita ya madzi ndizovuta kwambiri, zomwe zimakhudza mwachindunji metering ya mita ya madzi. Kusankhidwa kwa valavu yoyendetsera magetsi kuyenera kukhala ndi moyo wautali, kudalirika kwakukulu kwa kusintha, kutayika kochepa, ndipo sikophweka kukulitsa ntchito. Pakadali pano, valavu ya ceramic ndiyofunikira kwambiri.
