Chii chinonzi Trunnion ball valves?
Atrunnion bhora vharafuzvinoreva kuti bhora rinomanikidzwa nemabhengi uye rinongobvumirwa kutenderera, ruzhinji rwe hydraulic load inotsigirwa neSystem constraints, zvichiita kuti kuderedzwa kwepasi uye kusina shaft kuneta.
Thebhora vharafuimhando yequarter-turn valve inoshandisa mhango, perforated uye yakagadzika/inotsigirwa bhora kudzora kuyerera naro.
Mutsindo wepombi unotyaira chigaro chepamusoro pabhora rakamira zvekuti mutsetse unomanikidza chigaro chekumusoro pabhora zvichiita kuti iname.Iyo mechanic anchoring yebhora inotora kusundidzirwa kubva pakumanikidzwa kwemutsara, kudzivirira kukweshera kwakanyanya pakati pebhora nezvigaro, saka kunyangwe pakuzara kwakazara kushanda kumanikidza kushanda torque kunoramba kwakaderera.Izvi zvinonyanya kubatsira kana bhora revhavha richiitwa nekuti rinoderedza saizi yeactuator uye nekudaro mutengo wakazara wevhavha actuation package.Iyo trunnion inowanikwa kune ese saizi uye kune ese makirasi ekumanikidza asi iwo anonyanya hukuru hukuru uye yakanyanya kudzvanywa mamiriro.
Mamiriro makuru eNORTECH Trunnion bhora mavharuvhu
1.Double Block uye Bleed(DBB)
Kana vharuvhu yakavharwa uye mhango yepakati ichidururwa nevharuvhu yekuburitsa, zvigaro zvekumusoro nekudzika zvichavharika zvakazvimirira.Rimwe basa remudziyo wekuburitsa nderekuti chigaro chevharuvhu chinogona kutariswa kana paine kuvuza panguva yekuyedzwa.Mukuwedzera, madhipoziti mukati memuviri anogona kushambidzwa kuburikidza nemudziyo wekuburitsa.chigadzirwa chekuburitsa chakagadzirirwa kuderedza kukuvadzwa kwechigaro nekusachena mukati.
2.Low Operating Torque
Iyo trunnion pombi bhora vharafu inotora trunnion bhora chimiro uye chigaro chevharuvhu inoyangarara, kuitira kuti iwane yakaderera torque pasi pesimba rekushanda.Inoshandisa self-lubricating PTFE uye simbi inotsvedza kutakura kuderedza friction coefficient kusvika kune yakaderera pamwe chete nehupamhi hwepamusoro uye hunyoro hwepamusoro.
4.Fireproof Structure Design
Kana pakaitika moto panguva yekushandiswa kwevharuvhu, chigaro chechigaro, dzinde O mhete uye yepakati flange O rin'i yakagadzirwa nePTFE,rabha yezvimwe zvinhu zvisiri zvesimbi ichaparara kana kukuvadzwa pasi pekupisa kwakanyanya.Pasi pekumanikidzwa kwepakati, bhora. vharafu inosunda chibatiso chechigaro nekukurumidza chakananga kubhora kuita kuti mhete yesimbi ibatane nebhora uye igadzire simbi yekubatsira kuenda kusimbi yekuisa chisimbiso chimiro, chinogona kunyatso kudzora kuvuuka kwevharuvhu. Iyo isingapindi moto dhizaini yetrunnion pombi bhora vharafu inoenderana nezvinodiwa muAPI. 607, API 6FA, BS 6755 uye mamwe maitiro.
5.Anti-static Structure
Ivhavhavha yebhora yakagadzirwa neanti-static chimiro uye inotora static magetsi ekuburitsa mudziyo kuti igadzire yakananga chiteshi pakati pebhora nemuviri kuburikidza nedzinde, kuitira kuti ibudise iyo static magetsi inogadzirwa nekuda kwekukweshana panguva yekuvhurwa nekuvhara. bhora uye chigaro kuburikidza nepombi, kudzivirira moto wekuputika unogona kukonzerwa ne static spark uye nekuona kuchengetedza system.
7.Single Kuisa Chisimbiso
(Automatic Pressure Relief in Middle Cavity of Valve) Kazhinji, chisimbiso chimwe chete chinoshandiswa.Kureva kuti, pane chisimbiso chekumusoro chete.Sezvo chitubu chakazvimiririra chakaremerwa zvigaro zvekuvharisa kumusoro uye kuzasi kwerukova kuchishandiswa, kudzvanya kuri mukati mevhavhavhavha kunogona kukurira pre-kusimbisa mhedzisiro yechitubu, kuitira kuti chigaro chiburitswe kubva mubhora uye kuona otomatiki kudzoreredzwa kwakananga kune yakadzika chikamu. .Rutivi rwekumusoro kwerwizi: Kana chigaro chichifamba axially pamwe nevharuvhu, kudzvanywa "P" kunoitwa pachikamu chekumusoro (inopinza) inogadzira reverse simba paA1, Sezvo A2 yakakwirira kupfuura A1, A2-A1 = B1, simba riri pa B1 inosundira chigaro kubhora uye kuona kuvharika kwakasimba kwechikamu chekumusoro
Rutivi rwekudzika: Kana kudzvanywa "Pb" mukati mevharuvhu Cavity kunowedzera, simba rinoitwa paA3 rakakwirira kupfuura iro riri paA4.Sezvo A3-A4 = B2, kudzvanyirirwa kwakasiyana paB2 kuchakunda simba remuchirimo kuita kuti chigaro chiburitswe kubva mubhora uye kuona kudzoreredzwa kwevhavhavhavha kusvika kune yakadzika chikamu mushure, chigaro nebhora zvichanamwa zvakare pasi pechiitiko chechirimo. .
Chisimbiso chechipiri: Kudzika.
Kana kudzvinyirirwa kunenge kwadzikira kana pasina kudzvanyirira kusiyanisa, chigaro chinoyangarara chinofamba axially padivi pevharuvhu pasi pechitubu chiito uye kusundira chigaro chakananga kubhora kuti urambe wakasunga chisimbiso.Kana mavharuvhu anomanikidza P akawedzera, simba rinoitwa panzvimbo A4 yechigaro chevharuvhu kumusoro kupfuura simba rinoitwa panzvimbo A3, A4- A3 = B1. kuvhara kwakasimba kwechikamu chekumusoro.
9.Safety Relief Device
Sezvo vharuvhu yebhora yakagadzirwa neyekutanga chisimbiso chepuraimari uye chechipiri chisimbiso chine mbiri piston effect, uye mhango yepakati haigone kuona otomatiki kudzvinyirira, vharafu yekudzivirira inofanirwa kuiswa pamuviri kuitira kudzivirira njodzi yekunyanya-kudzvanywa kukuvara. mukati mevhavha yevhavha iyo inogona kuitika nekuda kwekuwedzera kwekushisa kwepakati.Kubatanidzwa kwevhavha yekudzivirira kwekuchengetedza kunowanzova NPT 1/2.Imwe pfungwa inofanirwa kucherechedzwa ndeyekuti yepakati yevhavha yekuyamura yekudzivirira inoburitswa zvakananga mumhepo.Kana kuyerera kwakananga mumhepo kusingabvumirwe, isu tinokurudzira kuti vharafu yebhora ine chimiro chakakosha cheotomatiki yekuyambutsa yakananga kurwizi rwepamusoro inofanira kushandiswa. Tarisa kune zvinotevera kuti uwane mamwe mashoko.Ndokumbira uzviratidze muhurongwa kana iwe usingade vharafu yekuyamura kana iwe uchida kushandisa vharafu yebhora ine chimiro chakasarudzika cheotomatiki kudzvinyirira kusimuka kuenda kumusoro kwerukova.
10.Special Structure yeAutomatic Pressure Relief Towards Upper Stream
Sezvo vharuvhu yebhora yakagadzirwa neyakavharidzirwa yepuraimari neyechipiri yekuisa chisimbiso ine mbiri piston athari, uye iyo yepakati mhango haigone kuona otomatiki kudzvinyirira, iye bhora vharafu iyo yakakosha dhizaini inokurudzirwa kuzadzisa zvinodiwa otomatiki kudzvinyirira uye kuona kuti hapana kusvibiswa. Muchimiro, rukova rwepamusoro runotora chisimbiso chekutanga uye rukova rwezasi runotora chisimbiso chekutanga uye chechipiri Kana vharafu yebhora yakavharwa, kudzvanywa kuri muvhavhavhavha kunogona kuona otomatiki kudzvinyirira kune kurukova rwekumusoro, kuti udzivise. Kana chigaro chepuraimari chakuvadzwa uye chadonha, chigaro chechipiri chinogonawo kuita chisimbiso. Asi kutarisisa kunofanirwa kubhadharwa kune kuyerera kwevhavhavha yebhora. kuzasi kwerukova nzira.Tarira kumifananidzo inotevera yekuvharisa musimboti wevharuvhu nechimiro chakakosha
Nheyo yekudhirowa kwevharuvhu yebhora kumusoro nekudzika kuvharika
Nheyo yekudhirowa kwebhora vharafu mhango yekuyaruka kune yekumusoro rukova uye pasi perukova chisimbiso
12.Corrosion Resistance uye Sulfide Stress Resistance
Imwe corrosion allowance yasarira kukora kwemadziro emuviri.
Iyo kabhoni simbi hunde, yakagadziriswa shaft, bhora, chigaro uye chigaro mhete zvinoiswa kune kemikari nickel plating zvinoenderana neASTM B733 uye B656. Pamusoro pezvo, zvinhu zvakasiyana-siyana zvinodzivirira corrosion zviripo kuti vashandisi vasarudze. Zvinoenderana nezvinodiwa nemutengi, mavharuvhu anogona kusarudzwa zvinoenderana neNACE MR 0175 / ISO 15156 kana NACE MR 0103, uye kwakasimba kudzora kwemhando uye kuongororwa kwemhando kunofanirwa kuitwa panguva yekugadzira kuitira kuzadzisa zvizere zvinodiwa mumazinga uye kusangana nemamiriro ebasa munzvimbo yesarufa.
Blow-out Proof Stem
13.Extension Stem
Kana iri vharuvhu yakanyudzwa, hunde yekuwedzera inogona kupihwa kana kushanda kwepasi kuchidikanwa.Dzinde rekuwedzera rinoumbwa nedzinde, jekiseni rejekiseni rinovhara, uye vharafu yemvura inogona kutambanudzwa kusvika kumusoro kuitira kuti basa rive nyore.Vashandisi vanofanirwa kuratidza izvo zvekuwedzera stem zvinodiwa uye kureba kana vachiisa maodha.Kune vharafu yebhora inofambiswa nemagetsi, pneumatic uye pneumatic - hydraulic actuators, kureba kwedzinde kunofanirwa kubva pakati pepombi kuenda kumusoro flange.
