Pneumatic control globe valve inozivikanwawo sepneumatic cut-off valve, imhando yeactuator mune otomatiki system, inosanganisira akawanda-spring pneumatic film actuator kana inoyangarara piston actuator uye inogadzirisa vharafu, inogamuchira chiratidzo chekudzora chiridzwa, kudzora kucheka. , kubatanidza kana kuchinja kwemvura mupombi yekugadzira.Iine maitiro ekugadzirisa nyore, mhinduro inonzwisisika uye chiito chakavimbika.Inogona kushandiswa zvakanyanya mu petroleum, makemikari indasitiri, simbi uye mamwe maindasitiri ekugadzira zvikamu.Iyo mhepo sosi yepneumatic cut-off valve inoda yakasefa yakamanikidzwa mweya, uye yepakati inoyerera kuburikidza nemuviri wevharuvhu inofanira kunge isina tsvina uye zvimedu zvemvura uye gasi.
Iyo silinda yepneumatic globe valve ndeye stereotyped chigadzirwa, chinogona kukamurwa kuita chimwe chiito uye kaviri chiito zvinoenderana nemaitiro echiito.Iyo imwechete-inobata chigadzirwa ine reset cylinder spring, iyo ine otomatiki reset basa rekurasikirwa nemhepo, kureva, kana silinda piston (kana diaphragm) iri pasi pechiito chechirimo, silinda yekusundira tsvimbo inodzoserwa kumashure kune yekutanga. nzvimbo ye cylinder (nzvimbo yepakutanga yekurohwa).Iyo kaviri-inobata silinda haina kudzoka chitubu, uye kumberi uye kudzoka kwetsvimbo yekusundidzira kunofanirwa kuenderana nenzvimbo yekupinza uye yekubuda kweiyo cylinder mhepo sosi.Kana sosi yemhepo ichipinda mukamuri yepamusoro yepiston, tsvimbo yekusundidzira inofamba ichidzika pasi.Kana sosi yemhepo ichipinda nepaburi rezasi repiston, tsvimbo yekusundidzira inoenda kumusoro.Nekuda kwekuti hapana reset chitubu, iyo kaviri-inobata silinda ine yakawandisa kupfuura yakafanana-dhayamita single-acting silinda, asi haina otomatiki reset basa.Zviripachena, nzvimbo dzakasiyana dzekutora dzinoita kuti putter ifambe munzira dzakasiyana.Kana nzvimbo yekupinda mhepo iri mugomba rekumashure remudonzvo wekusundidzira, kupinza kwemhepo kunoita kuti mudonzvo ufambire mberi, nenzira iyi inonzi positive cylinder.Pane zvinopesana, kana nzvimbo yekupinda mhepo iri kudivi rimwe chete retsvimbo yekusundidzira, kupinza kwemhepo kunoita kuti tsvimbo yekudzosera kumashure, iyo inonzi reaction cylinder.Pneumatic globe valve nekuti iyo yakawanda inoda kurasikirwa nemhepo yekudzivirira basa, kazhinji shandisa imwechete inoita silinda.

1. chimiro chevharuvhu chemuviri chine chigaro chimwe chete, sleeve, chigaro cheviri (mbiri nhatu-nzira) mhando nhatu, mafomu ekusimbisa ane chisimbiso chekurongedza uye mabhero anosimbisa marudzi maviri, chigadzirwa chezita rekumanikidza giredhi PN10, 16, 40, 64 marudzi mana, nominal caliber range DN20 ~ 200mm.Inoshanda tembiricha yemvura kubva -60 kusvika 450 ℃.Iyo leakage level ikirasi IV kana Kirasi VI.Kuyerera hunhu kukurumidza kuvhura;
2. iyo yakawanda-spring actuator uye nzira yekugadzirisa yakabatana nemakoroni matatu, urefu hwose hunogona kuderedzwa neanenge 30%, uye uremu hunogona kuderedzwa ne30%;
3. muviri wevharuvhu wakagadzirwa maererano nemusimboti wemagetsi mechanics mune yakaderera kuyerera kwekudzivirira kuyerera chiteshi, yakayerwa kuyerera kwekofi yakawedzera ne30%;
4. chikamu chekuisa chisimbiso chezvikamu zvemukati zvevharuvhu zvine marudzi maviri echisimbiso chakasimba uye chakapfava, chisimbiso chakasimba chepamusoro pe cemented carbide, chisimbiso chakapfava chemhando yakapfava, kuita chisimbiso chakanaka kana chakavharwa;
5. kuenzana kwevhavha yemukati, kunatsiridza kubvumidzwa kunobvumirwa kusiyana kwevhavha yakachekwa;
6. Chisimbiso chine mabhero chinoumba chisimbiso chakazara pahunde yevharuvhu inofamba, ichivharira mukana wekudonha kwepakati;
7, piston actuator, simba guru rekushanda, kushandiswa kwemusiyano mukuru wekumanikidza.
Munguva yekuvhura nekuvhara nzira yesimbi yakaumbwa yeglobe valve, nekuti kukweshera pakati pe disc uye yekuvharisa pamusoro pemuviri wevharuvhu idiki pane iyo yevhavha yegedhi, haibatike.
Kuvhura kana kuvhara kwevhavha hunde ipfupi, uye ine yakavimbika kwazvo yekucheka-kubvisa basa, uye nekuti shanduko yevhavha chigaro chechiteshi inoenderana nekurohwa kwevhavha disc, yakakodzera kwazvo kugadzirisa. yehuwandu hwekuyerera.Naizvozvo, rudzi urwu rwevharuvhu rwakanyatsokodzera kucheka-kubvisa kana kudzora uye throttling.
Senyanzvi yePneumatic Actuator Kudzora Gedhi Valve uye mutengesi kunze, tinovimbisa kupa vatengi nemhando yepamusoro-soro mushure mekutengesa sevhisi, kusanganisira zvinotevera:
1.Kupa mazano ekushandiswa kwechigadzirwa uye mazano ekugadzirisa.
2.Nekukundikana kunokonzerwa nezvinetso zvehutano hwechigadzirwa, tinovimbisa kupa rubatsiro rwehutano uye kugadzirisa matambudziko mukati menguva pfupi.
3.Kunze kwekukuvara kunokonzerwa nekushandiswa kwakajairika, tinopa mahara kugadzirisa uye kutsiva masevhisi.
4.Tinovimbisa kupindura nokukurumidza kune zvinodiwa nevatengi panguva yewaranti yechigadzirwa.
5. Isu tinopa tsigiro yenguva refu yehunyanzvi, kubvunzana pamhepo uye masevhisi ekudzidzisa.Chinangwa chedu ndechekupa vatengi ruzivo rwakanyanya rwesevhisi uye kuita kuti ruzivo rwevatengi ruwedzere kunakidza uye nyore.
