Globe mavharuvhudzave dziri tsigiro mukudzora mvura kwemakore 200 uye zvino dzave kuwanikwa kwese kwese. Nekudaro, mune mamwe maapplication, dhizaini yeglobe valve inogona kushandiswawo kubata kuvharika kwese kwemvura. Globe mavharuvhu anowanzo shandiswa kudzora kuyerera kwemvura. Globe vharafu pa/kudzima uye modulating kushandiswa kunogona kuonekwa kunze kwedzimba uye bhizinesi zvimiro, uko mavharuvhu anogara achiiswa.

Utsi nemvura zvaikosha kuChinjo yeIndasitiri, asi zvinhu izvi zvinogona kuva nengozi zvaifanira kudziviswa. Theglobe valvendiyo vharuvhu yekutanga inodiwa kupedza basa iri nemazvo. Dhizaini yevharuvhu yepasi rose yakabudirira uye yakafarirwa zvakanyanya zvekuti yakatungamira kune ruzhinji rwevagadziri echinyakare mavharuvhu (Crane, Powell, Lunkenheimer, Chapman, naJenkins) vagamuchire matende avo ekutanga.

Mavharuvhu egedhizvakagadzirirwa kushandiswa munzvimbo dzakavhurika zvizere kana dzakavharwa zvakazara, nepo mavharuvhu eglobe anogona kushandiswa sevhavhavhavha kana yekuzviparadzanisa asi akagadzirirwa kuvhurika zvishoma kudzora kuyerera kana uchironga. Kuchengetedza kunofanira kushandiswa mumagadzirirwo ekugadzirisa paunenge uchishandisa mavharuvhu ekuzviparadzanisa-anoshanda uye ari-kuvharika mavharuvhu, sezvo zvakaoma kuchengetedza chisimbiso chakasimba nekusundidzira kukuru pane disc. Simba remvura richabatsira kuwana chisimbiso chakanaka uye kuita kuti zvive nyore kuvhara kana mvura inoyerera kubva kumusoro kusvika pasi.

Globe mavharuvhu akanakira kudzora mavharuvhu mashandisirwo nekuda kwekuita kwayo kudzora, izvo zvinobvumira kurongeka kwakanyanya nemapositioners uye actuators akabatana neglobe valve bonnet uye dzinde. Ivo vanokunda muhuwandu hwemashandisi ekudzora mvura uye vanonzi mune izvi zvikumbiro se "Final Control Elements."

nzira yekuyerera isina kunanga

Iyo Globe inozivikanwawo sevharuvhu nekuda kwechimiro chayo chekare chakatenderera, icho chichiri kuvanza nzira yekuyerera isina kujairika uye yakavhiringika. Nematanho ayo ekumusoro neazasi akaiswa serrated, vharafu yeglobhu yakazaruka ichiri kuratidza kukweshera kwakakosha kana chipingamupinyi chekuyerera kwemvura mukupesana negedhi rakavhurika zvizere kana vharafu yebhora. Fluid friction inokonzerwa nekuyerera kwakarereka kunonotsa kupfuura nemuvharuvhu.

Iyo inoyerera coefficient, kana "Cv," yevharuvhu inoshandiswa kuverenga kuyerera kwayo. Mavharuvhu egedhi ane kushomeka kwekuyerera kwekuramba kana ari munzvimbo yakavhurika, saka Cv ichave yakasiyana zvakanyanya kune gedhi vharuvhu uye globe vharafu yehukuru hwakafanana.

Iyo disc kana plug, iyo inoshanda sevhavhavhavha yevhavha yekuvhara nzira, inogona kugadzirwa mune akasiyana maumbirwo. Chiyero chekuyerera kuburikidza nevharuvhu chinogona kushanduka zvakanyanya zvichienderana nenhamba yehunde yemaspins kana vharuvhu yakavhurika nekushandura chimiro che disc. Iyo yakajairika kana "yechinyakare" curved disc dhizaini inoshandiswa muhuwandu hwemaapplication nekuti inokodzera zvirinani pane mamwe magadzirirwo kune chaiyo kufamba (kutenderera) kwevharuvhu stem. Madhisiki eV-port akakodzera hukuru hwese mavharuvhu epasi uye akagadzirirwa kudzora kuyerera kwakanaka muzvikamu zvakasiyana zvekuvhura. Mhedziso yekuyerera kwemutemo ndicho chinangwa chemhando dzetsono, zvisinei ivo vanowanzopihwa mumadhayamita madiki. Yekupinza yakapfava, inosimba inogona kuiswa mudhisiki kana chigaro kana kudzima kuzere kuchidikanwa.

Globe valve trim

Iyo chaiyo chikamu-ku-chikamu chekuvhara muvhavhavha yepasi inopiwa ne spool. Chigaro, dhisiki, dzinde, chigaro chekumashure, uye dzimwe nguva Hardware inonamira hunde kune disc inoumba chidimbu chevharuvhu. Chero kushanda zvakanaka kwevharuvhu uye hupenyu hunoenderana nedhizaini yekugadzira uye sarudzo yezvinhu, asi mavharuvhu eglobhu ari panjodzi zvakanyanya nekuda kwekukwesha kwemvura uye nzira dzakaoma dzekuyerera. Velocity yavo uye mhirizhonga inosimuka sezvo chigaro nedhisiki zvichiswedera kune imwe. Pamusana pekuora kwemvura uye kuwedzera kwekukurumidza, zvinokwanisika kukuvadza chivharo chevhavha, iyo ichawedzera zvakanyanya kubuda kwevhavha kana yakavharwa. Tambo ishoko remhosho rinopota richionekwa sediki diki pachigaro kana disc. Izvo zvakatanga senzira diki yekuvuza inogona kukura uye kushanduka kuita inodonha yakakosha kana ikasagadziriswa nenguva.

Iyo plug yevharuvhu pamavharuvhu madiki ebhuronzi anowanzo gadzirwa nezvinhu zvakafanana nemuviri, kana dzimwe nguva arobust-senge alloy. Iyo yakajairika spool zvinhu zvecast iron globe mavharuvhu ibhuronzi. IBBM, kana kuti "Iron Body, Bronze Mounting," ndiro zita reiyi iron trim. Kune zvakawanda zvakasiyana-siyana zvekucheka zviwanikwa zviripo zvemavharuvhu esimbi, asi kazhinji imwe kana akawanda ekucheka zvinhu anogadzirwa ne400 akatevedzana martensitic simbi isina tsvina. Pamusoro pezvo, zvinhu zvakaoma senge stellite, mazana matatu akateedzana masimbi asina tsvina, uye copper-nickel alloys seMonel anoshandiswa.

Kune matatu akakosha modes eglobe mavharuvhu. Chimiro che "T", chine stem perpendicular kuyerera kwepombi, ndiyo inonyanya kufanana.

Kufanana ne-T-valve, valve yekona inotenderera kuyerera mukati mevhavha 90 madhigirii, ichiita sesese mudziyo wekudzora kuyerera uye 90 degree pombi gokora. Pamafuta uye gasi "miti yeKisimusi," angle yeglobe mavharuvhu ndiyo mhando yekupedzisira yekubuda inodzora vharafu iyo ichiri kushandiswa kazhinji pamusoro pemaboilers.

Iyo "Y" dhizaini, inova yechitatu dhizaini, inoitirwa kuomesa dhizaini yekubatidza / kudzima maapplication uku ichideredza kuyerera kunoitika mumuviri wevharuvhu. Iyo bhoneti, dzinde, uye dhisiki yerudzi urwu rwevharuvhu inotenderedzwa pakona ye30-45 madhigirii kuita kuti nzira yekuyerera inyatsotwasuka uye kuderedza kukwesha kwemvura. Nekuda kwekudzikira kwekukweshana, vharuvhu haine mukana wekuchengetedza kukuvara kwekukura uye pombi system yekuyerera kwese inovandudzwa.
