Iwo Makuru Mabasa & Sarudzo Nheyo dzeMavharuvhu

Mavharuvhu chinhu chakakosha cheindasitiri pombi masisitimu uye anoita basa rakakosha mukuita kwekugadzira.

Ⅰ. Basa guru revhavha

1.1 Kuchinja uye kucheka midhiya:vharafu yegedhi, butterfly valve, bhora revhavha rinogona kusarudzwa;

1.2 Dzivirira kuyerera kwepakati:cheki vharafuinogona kusarudzwa;

1.3 Gadzirisa kudzvinyirira uye kuyerera kwepakati yepakati: sarudzo yekuvhara-vhavhavhavha uye yekudzora valve;

1.4 Kupatsanura, kusanganisa kana kugovera midhiya: plug valve,vharafu yegedhi, vharafu yekudzora inogona kusarudzwa;

1.5 Dzivirira kudzvinyirira kwepakati kubva pakudarika kukosha kwakatarwa kuti uve nechokwadi chekushanda kwakachengeteka kwepombi kana midziyo: valve yekuchengetedza inogona kusarudzwa.

Kusarudzwa kwevhavha kunonyanya kubva pakuona kwekushanda kusina matambudziko uye hupfumi.

Ⅱ. Basa revhavha

Pane akati wandei akakosha zvinhu zvinosanganisirwa, uye heino rondedzero yakadzama pamusoro pazvo:

2.1 Mamiriro emvura inotakura

Fluid Type: Kunyangwe iyo fluid iri mvura, gasi, kana mhute inokanganisa zvakananga sarudzo yevharuvhu. Semuenzaniso, zvinwiwa zvingada kuvhara-vharavhavha, nepo magasi angave akakodzera mavharuvhu ebhora. Corrosiveness: Mvura inoparadza inoda zvinhu zvisingadziviriri zvakadai sesimbi isina tsvina kana ma alloys chaiwo. Viscosity: Mvura yakakwira-viscosity inogona kuda madhayamita akakura kana mavharuvhu akagadzirwa kuti aderedze kuvhara. Particle zvirimo: Fluids ine zvimedu zvakasimba zvinogona kuda kusakara-yekupfeka kana mavharuvhu akagadzirwa, akadai sepinch mavharuvhu.

2.2 Basa revhavha

Switch control: Pazviitiko zvinongodiwa chete basa rekuchinja, mavharuvhu ebhora kanagedhi mavharuvhuisarudzo dzakajairika.

Flow Regulation: Kana kudzora kuyerera chaiko kuchidikanwa, mavharuvhu eglobhu kana mavharuvhu ekudzora akanyanya kukodzera.

Backflow Prevention:Tarisa mavharuvhuanoshandiswa kudzivirira kubuda kwemvura.

Shunt kana Kubatanidza: Ivhavha yenzira nhatu kana nzira dzakawanda inoshandiswa kutsausa kana kubatanidza.

2.3 Saizi yevharuvhu

Kukura kwepombi: Saizi yevharuvhu inofanirwa kuenderana nehukuru hwepombi kuti ive nechokwadi chekufamba kwemvura. Kuyerera kunodiwa: Saizi yevhavha inoda kusangana nehurongwa hwekuyerera zvinodiwa, uye yakakura kana diki zvakanyanya ichakanganisa kushanda kwayo. Kuisa Nzvimbo: Kuisa nzvimbo zvipingamupinyi zvinogona kukanganisa saizi yevharuvhu kusarudzwa.

2.4 Kuramba kurasikirwa kwevhavha

Kudonhedza kudonhedza: Ivhavha inofanirwa kuderedza kudonhedzwa kwekumanikidza kuti isakanganisa kushanda kwehurongwa.

Kuyerera dhizaini dhizaini: Mavharuvhu akazara, akadai seakazara bhora mavharuvhu, kuderedza kurasikirwa kwekudhonza.

Rudzi rwevharuvhu: Mamwe mavharuvhu, senge butterfly mavharuvhu, ane kushomeka kushoma kana akavhurwa, achiita kuti ave akakodzera kuderera kwekudonha nguva.

2.5 Kupisa kwekushanda uye kushanda nesimba kwevhavha

Tembiricha renji: Zvishandiso zvevharuvhu zvinoda kuchinjika kune tembiricha yemvura, uye zvinhu zvinodzivirira tembiricha zvinoda kusarudzwa munzvimbo dzakakwirira kana dzakaderera tembiricha.

Chiyero chekumanikidza: Ivhavha inofanirwa kukwanisa kumira zvakanyanya kushanda kwemaitiro, uye iyo yepamusoro-yepamusoro-soro system inofanira kusarudza valve ine high pressure level.

Yakasanganiswa kukanganisa kwetembiricha uye kumanikidza: Tembiricha yepamusoro uye yakanyanya kudzvanywa nharaunda inoda kutariswa kwakanyanya kwesimba rezvinhu uye yekuisa chisimbiso.

2.6 Zvinhu zvevhavha

Corrosion resistance: Sarudza zvinhu zvakakodzera zvichibva pakuora kwemvura, sesimbi isina tsvina, Hastelloy, nezvimwe.

Mechanical simba: Iyo valve zvinhu inoda kuve neyakakwana simba remagetsi kuti rimire kushanda nesimba.

Tembiricha inochinjika: Izvo zvinhu zvinoda kuchinjika kune tembiricha yekushanda, iyo yakanyanya tembiricha nharaunda inoda zvinhu zvinodzivirira kupisa, uye yakadzika-tembiricha nharaunda inoda kutonhora-inodzivirira zvinhu.

Economy: Pachimiro chekusangana nekuita zvinodiwa, sarudza zvinhu zvine hupfumi huri nani.
