Chii chinonzi apressure regulating valve?
Padanho rekutanga, vharuvhu yekudzora dhizaini chigadziriso chakagadzirirwa kudzora kumusoro kana kudzika kudzvinyirira mukupindura shanduko muhurongwa. Shanduko idzi dzinogona kusanganisira kuchinjika mukuyerera, kudzvanywa, tembiricha kana zvimwe zvinhu zvinoitika panguva yekushanda kwehurongwa. Chinangwa chemutongi wekumanikidza ndechekuchengetedza inodiwa system pressure. Zvinonyanya kukosha, zvinodzvinyirira zvinosiyana zvakasiyana nemavharuvhu, ayo anodzora system kuyerera uye haagadzirise otomatiki. Dzvinyiriro inodzora mavharuvhu inodzora kudzvanywa, kwete kuyerera, uye inozvidzora.

Pressure regulator mhando
Kune marudzi maviri makuru emagetsi ekudzora mavharuvhu:kudzvinyirira kuderedza mavharuvhu uye kumashure kudzvinyirira mavharuvhu.

Dzvinyiriro yekudzikisa mavharuvhu inodzora kuyerera kuyerera kune iyo nzira kuburikidza nekuona kubuda kwekumanikidza uye kudzora kudzika kudzika kwayo.

Back pressure regulators inodzora kudzvanywa kubva pakuita nekuona inlet pressure uye kudzora kudzvanywa kubva kumusoro

Yako yakanakira pressure regulator kusarudzwa kunoenderana nezvaunoda maitiro. Semuenzaniso, kana iwe uchida kuderedza kudzvinyirira kubva kune-high-pressure sosi isati yasvika system media inosvika padanho guru, kumanikidza kudzikisa valve kunogona kuita basa. Kusiyana neizvi, chivharo chekumashure chinobatsira kudzora nekuchengetedza kukwira kwepamusoro nekuderedza kudzvinyirira kwakanyanya apo mamiriro ehurongwa anoita kuti kumanikidzwa kuve kwakakwirira kudarika zvinodiwa. Kana yakashandiswa munzvimbo yakakodzera, mhando yega yega inogona kukubatsira kuchengetedza inodiwa kudzvanywa mukati mese system yako.

Kushanda musimboti wepressure regulating valve
Mavharuvhu ekudzvanya ane zvinhu zvitatu zvakakosha zvinovabatsira kudzora kudzvanywa:

Kudzora zvinhu, kusanganisira chigaro chevharuvhu uye poppet. Chigaro chevharuvhu chinobatsira kudzora kudzvanywa uye chinodzivirira mvura kubva kune rumwe rutivi rweregulator kana yakavharwa. Ipo sisitimu iri kuyerera, poppet uye chigaro chevharuvhu zvinoshanda pamwechete kupedzisa kuvharwa kwechisimbiso.

Sensing element, kazhinji diaphragm kana piston. Iyo inonzwa chinhu chinoita kuti poppet isimuke kana kudonha muchigaro chevharuvhu kudzora inlet kana yekubuda pressure.

Loading Elements. Zvichienderana nekushandiswa, mutongi anogona kunge ari chitubu-akatakura regulator kana dome-yakatakura regulator. Chinhu chekurodha chine simba rekudzika rinodzika pamusoro pe diaphragm.

Zvinhu izvi zvinoshanda pamwechete kugadzira iyo inodiwa kudzora kudzvinyirira. Piston kana diaphragm inonzwa kukwira (inlet) kudzvanywa uye kudzika (kubuda) kudzvanywa. Chinhu chekunzwa chinozoyedza kuwana chiyero neseti simba kubva pane yekurodha, iyo inogadziriswa nemushandisi kuburikidza nemubato kana imwe nzira yekutenderera. Chinhu chekunzwa chinogonesa poppet kuvhura kana kuvhara kubva pachigaro chevharuvhu. Zvinhu izvi zvinoshanda pamwe chete kuchengetedza kuenzana uye kuwana kumanikidzwa kwakaiswa. Kana simba rimwechete richichinja, rimwe simba rinofanirawo kuchinja kuti ridzorere kuenzana.

Muvhavha inoderedza kudzvinyirira, masimba mana akasiyana anofanira kuenzana, sezvinoratidzwa mumufananidzo 1. Izvi zvinosanganisira simba rekutakura (F1), inlet spring force (F2), kubuda kwemhepo (F3) uye inlet pressure (F4). Iyo yakazara kurodha simba inofanirwa kuenzana nekubatanidzwa kwe inlet chitubu simba, yekubuda pressure, uye inlet pressure.

Back pressure valves inoshanda nenzira yakafanana. Vanofanira kuenzanisa chitubu simba (F1), inlet pressure (F2) uye outlet pressure (F3) sezvinoratidzwa muMufananidzo 2. Pano, simba remvura rinofanira kuenzana nehuwandu hwekumanikidzika kwekupinza uye kubuda kwemhepo.

Kuita iyo Right Pressure Regulator Sarudzo
Kuisa yakaringana saizi pressure regulator ndiyo kiyi pakuchengetedza kudzvanywa kunodiwa. Saizi yakakodzera kazhinji inotsamira pachiyero chekuyerera muhurongwa - maregulator makuru anogona kubata kuyerera kwepamusoro apo achidzora kudzvanywa zvinobudirira, nepo kune yakaderera kuyerera kwemazinga, madiki ekudzora anoshanda zvakanyanya. Izvo zvakakoshawo kuyera saizi yezvigadziriso zvikamu. Semuenzaniso, zvingave zvakanyanya kushanda kushandisa diaphragm hombe kana piston kudzora kuderera kwekumanikidza maapplication. Zvese zvikamu zvinofanirwa kuve zvakakura zvakaringana zvichienderana nezvinodiwa zvesystem yako.

System pressure
Sezvo basa rekutanga remudhinda regidhi ndere kubata system kudzvanywa, zvakakosha kuti uve nechokwadi chekuti regulator yako yakakura kune iyo yakanyanya, hushoma, uye system inoshanda kumanikidza. Pressure regulator chigadzirwa maratidziro anowanzo simbisa iyo dhizaini yekudzora renji, iyo yakakosha pakusarudza yakakodzera kudzvanywa regulator.

Kupisa kwehurongwa
Maindasitiri maitiro anogona kuve nehupamhi hwetembiricha mazinga, uye iwe unofanirwa kuvimba kuti iyo inodzvinyirira regulator yaunosarudza inomira yakajairwa yekushanda mamiriro anotarisirwa. Zvinhu zvezvakatipoteredza ndezvimwe zvezvinhu zvinoda kutariswa, pamwe chete nezvinhu zvakadai sekushisa kwemvura uye Joule-Thomson effect, iyo inokonzera kutonhora nokukurumidza nekuda kwekudonha kwekumanikidzwa.

process senitivity
Process senitivity inobata basa rakakosha pakusarudza kusarudzwa kwemaitiro ekudzora mukumanikidza regulators. Sezvambotaurwa pamusoro apa, vatongi vazhinji ndevechitubu-vakaremerwa zvigadziriso kana dome-yakatakura regulators. Spring-loaded pressure regulator mavharuvhu anodzorwa nemushandisi nekutenderedza mubato wekunze unotenderera unodzora simba rechirimo pane chinhu chekunzwa. Kusiyana neizvi, dome-loaded regulators anoshandisa iyo fluid pressure mukati mesisitimu kuti ipe kudzvanywa kweseti kunobata pane inonzwa chinhu. Kunyangwe zvitubu-zvakaremerwa zvigadziriso zvakajairika uye vashandisi vanowanzo kujairana nazvo, dome-yakarodha regulator inogona kubatsira kuvandudza huchokwadi mumashandisirwo anoida uye inogona kubatsira mune otomatiki regulator application.

system media
Material kuenderana pakati pezvikamu zvese zvepressure regulator uye system media kwakakosha kune chikamu chehupenyu hurefu uye kudzivirira downtime. Kunyangwe zvimiro zverabha uye elastomer zvichipinda kumwe kushatiswa kwechisikigo, mamwe masisitimu midhiya inogona kukonzera kukurumidza kuderedzwa uye kutadza kwevhavhavhavha yekudzora nguva isati yakwana.

Mavharuvhu anodzora mavharuvhu anoita basa rakakosha mune akawanda maindasitiri emvura uye zviridzwa masisitimu, zvichibatsira kuchengetedza kana kudzora kunodiwa kudzvanywa uye kuyerera mukupindura shanduko yehurongwa. Kusarudza iyo chaiyo pressure regulator kwakakosha kuti system yako irambe yakachengeteka uye iite sezvaitarisirwa. Sarudzo isiriyo inogona kutungamira mukusashanda zvakanaka kwehurongwa, kusaita zvakanaka, kugadzirisa dambudziko, uye njodzi dzinogona kuitika.
