Ball Valve vs. Gate Valve: Ndeipi Yakanakisa Yekushandisa Kwako?

Ona Mufananidzo Mukuru
Kune akawanda mavharuvhu eindasitiri anowanikwa pamusika.Mhando dzakasiyana dzemaindasitiri mavharuvhu anoshanda zvakasiyana.Vamwe vanoronga mafambiro ezvenhau asi vamwe vachitsaura midhiya.Vamwe vanodzora gwara rezvinobudisa nhau.Izvi zvinosiyanawo mumagadzirirwo uye hukuru.

Mavharuvhu maviri anonyanya kushandiswa mumaindasitiri ekushandisa mavharuvhu ebhora nemavharuvhu egedhi.Ose ari maviri anozivikanwa kupa akasimba ekuvharira-maitiro maitiro.Ichi chinyorwa chichafananidza mavharuvhu maviri muzvinhu zvakasiyana senge mashandisirwo ekushanda, magadzirirwo, madoko, uye zvinodaro.

Chii chinonzi Ball Valve?

Ivhavhavha yebhora chikamu chemhuri yekota-turn valve.Inongotora 90-degree kutendeuka kuti ivhure kana kuvhara.Dhizaini yevharuvhu yebhora ine bhora rakavharwa-kunze rinoita sedhisiki rinobvumira kuyerera kwenhau.Kunyanya kune asiri-slurry application, mavharuvhu ebhora akakodzerawo maapplication anoda kuvharika kwakasimba.

Iko kukurumidza kuvhura uye kuvhara kwebhora kunoita kuti ive yakakosha mune mamwe maapplication anoda media ega.Mavharuvhu ebhora anowanzoshandiswa mune yakaderera-kudzvanywa zvikumbiro.Muchidimbu, mavharuvhu ebhora akanakira kutonga uye manejimendi enhau nekudonha kushoma kwekumanikidza.

Chii chinonzi Gate Valve?

Kune rumwe rutivi, mavharuvhu emagedhi ndeemhuri yemutsara inofamba valve.Zvikasadaro inozivikanwa sevharuvhu yebanga kana slide vharafu, vharafu yegedhi ine flat kana wedge disc inoshanda segedhi.Iri gedhi kana disc inodzora kuyerera kwemvura mukati mevharuvhu.Ivhavhavha yegedhi inoshandiswa zvakanyanya kana mutsara wekuyerera kwe media ine kushomeka kuderera kunodiwa.

Ivharuvhu yevhavha ine throttling capacity.Inoitirwa zvakanyanya kuyerera kwezvinhu sekuyerera kwemutemo.Yakanyanya kukodzera kune yakakora kuyerera midhiya, iyo flat disc yemavharuvhu egedhi inoita kuti zvive nyore kucheka nemhando yakadaro ye media.

Ivhavhavha yegedhi zvakare chikamu chemhuri inotenderera sezvo vhiri kana actuator inoda kutenderedzwa kuti wedge kana disc izaruke.Nokuda kwechinzvimbo chayo chekuvhara, gedhi rinofamba richidzika uye pakati pezvigaro zviviri zviri pachikamu chepamusoro che disc pamwe nechepasi payo sezvakaratidzwa mumufananidzo uri pamusoro.

Gate Valve vs. Ball Valve: Working Mechanism

Bharavhavha Inoshanda Sei?

Mavharuvhu ebhora ane denderedzwa rinobvumira kufamba kwe media.Kana iwe ukatarisa pamuchinjikwa-chikamu chevhavha yebhora pazasi, kushanda kuri kuburikidza nekutenderera kweshaft kana tsinde nechikamu chechina chekutendeuka.Dzinde iri perpendicular kune chikamu chebhora chevharuvhu.

Fluid inotenderwa kupfuura kana dzinde riri pakona chaiyo maererano nedhisiki rebhora.The lateral kufamba kwevezvenhau kunoita basa rakakosha mukuvhara-kuvharwa kwemaitiro.Mavharuvhu ebhora anoshandisa kudzvinyirirwa kwemvura kuita pane vharafu kana chigaro kuti ipe chisimbiso chakasimba, zvichienderana nekugadziriswa kwevharuvhu.

Mavharuvhu ebhora anogona kuve akazara chiteshi kana kuderedzwa chiteshi.A full port ball valve zvinoreva kuti dhayamita rayo rakafanana nenyere.Izvi zvinobvumira kuderera kwekushanda torque uye kudonha kwekumanikidza.Nekudaro, kune zvakare yakaderedzwa chiteshi mhando apo saizi yevharuvhu iri saizi imwe idiki pane iyo yehukuru hwepombi.

Gedhi Vavhavha Inoshanda Sei?

Mavharuvhu egedhi anoshanda nekusimudza gedhi kana dhisiki kuti media ipfuure nepavharuvhu.Aya marudzi emavharuvhu anongobvumira unidirectional kuyerera nekuderera kushoma kuderera.Waiwanzoona mavharuvhu emagedhi ane mavhiri emaoko.Ruoko rworuoko rwakasungirirwa pakurongedza.

Kune marudzi maviri egedhi valve stem madhizaini.Kana iri vhiri remaoko richitenderera, tsinde inokwira kune imwe nzvimbo yekunze uye, panguva imwechete, inosimudza gedhi.Imwe mhando yevhavha yegedhi ivharuvhu yegedhi isingasimuke.Izvi zvinoratidzwa nedzinde rakarukwa mukati meweji, nokudaro richiisa pachena kune vezvenhau.

Kana gedhi revhavha richivhurwa, nzira inova yakakura.Iyo nzira yekuyerera haina mutsara mupfungwa yekuti midhiya inogona kutora chisipo sekuonekwa mumufananidzo uri pazasi.Kana vheji yegedhi ichishandiswa se throttle, inenge iine kusaenzana kwekuyerera.Izvi zvichaita kuti vibration.Kudengenyeka kwakadaro kunogona kukonzera kukanganisa kudhisiki.

Valve Flow Direction

Mavharuvhu ebhora nemavharuvhu egedhi, negungano, ari maviri-directional.Izvi zvinoreva kuti mavharuvhu ebhora ane simba rekuvharisa midhiya kubva kumagumo ekumusoro uye kumucheto kwakadzika.Tarisa mufananidzo uri pasi apa.

Valve Seal Capacity

Kune mavharuvhu ebhora, zvisimbiso zvinogona kugadzirirwa dhizaini yebhora inoyangarara uye inogona kuyangarara kune trunnion-yakaiswa bhora vharafu.Sezvo mavharuvhu ebhora achiwanzo shandiswa mune yakaderera-kudzvanywa zvikumbiro, tichifunga nezve hunhu hwekushanda kwayo, zvisimbiso zvekutanga zvinowanzogadzirwa nePTFE uye zvimwe zvine chekuita nazvo.

Nepo kukurumidza kuvhara nekuvhurwa kwevhavha yebhora kunogona kubatsira, izvi zvinogona kukonzera mamwe matambudziko.Mavharuvhu ebhora anowanzoita sando yemvura kana kukurumidza kusimuka kwekumanikidza pakuvhara kwevhavha.Ichi chirwere chinokuvadza zvigaro zvevhavha yebhora.

Uyezve, nyundo yemvura inogona kuwedzera kumanikidzwa mukati mevhavha yebhora.Mukushandiswa uko mamiriro akadai anogona kuitika, kureva zvinhu zvinopisa, pane chisimbiso chechigaro chekukurumidzira, chinowanzoitwa nesimbi.Ichi ndicho chipingamupinyi chechipiri mumamiriro ezvinhu apo elastomeric chisimbiso chinokuvadzwa mumasevhisi ekumanikidza.Kuti udzikise kumanikidzwa, mavharuvhu ebhora anogona kuve nepressure vent yakaiswa.

Mavharuvhu egedhi anoderedza kudonhedza kwepressure kana akazarurwa zvakazara.Izvi zviri kuburikidza nekushandisa yakazara bore port dhizaini.Izvi zvinoreva kuti saizi yevhavha yakaenzana nehukuru hwepombi.Imhaka yeuhu hunhu hwemavharuvhu emagedhi anovapa mukana pane mavharuvhu ebhora.Kunyura kwemvura hakuitike mumavhavha emagedhi.

Iyo yakaderera yevhavha yegedhi ndeye, yakakwira-kudzvanywa kusiyanisa kunowanzoitika mukuvhara.Iko kupokana kunogona kukonzera chigaro uye dhisiki kupfeka.

Valve Dhizaini uye Kuvaka Kusiyana

Musiyano mukuru pakati pemavharuvhu ebhora uye mavharuvhu egedhi chimiro chavo kunyangwe iwo anoshanda zvakafanana.

Kune mavharuvhu ebhora, kufamba kwe media kune kusununguka-kuyerera.Kunze kweizvi, dhizaini yevhavha yebhora inobvumira kuti igare kwenguva yakareba kunyangwe mushure mekushandisa zvakanyanya.Chokwadika, munhu anofanirawo kufunga nezverudzi rwezvinhu zviri kushandiswa kuchigadzira.

Nepo mavharuvhu ebhora asingape kutonga kwakanaka, kugona kwavo kuvharika ndeimwe yeakanakisa kune yakaderera-kudzvanywa maapplication.Mavharuvhu ebhora anovimbika mune izvi.Kurasikirwa kwepasi-kudzvinyirira ndeimwe yehutano hwemavharuvhu ebhora.Nekudaro, nekuda kwekota-kutendeuka kugona kwemavharuvhu ebhora, zvinotora nzvimbo yakawanda.

Ivhavha yegedhi, kune rumwe rutivi, inoshandisa handwheel kuvhura kana kuvhara disc.Muviri wevharuvhu zvakare wakanyanya kutetepa, nekudaro, chete nzvimbo yakamanikana inodiwa.Mukupesana nebhora mavharuvhu, gedhi mavharuvhu, kupa yakawedzera kunatswa kudzora sezvo ane throttling mano.Inogona kunge isina kukurumidza kuvharwa uye pakugona, asi inogona kudzora kwete chete midhiya inoyerera asiwo kumanikidza kwayo.
