Chii chinonzi Electric trunnion ball valve?
AnElectric trunnion ball valvezvinoreva kuti bhora rinomanikidzwa nemabhengi uye rinongobvumirwa kutenderera, ruzhinji rwe hydraulic load inotsigirwa neSystem constraints, zvichiita kuti kuderedzwa kwepasi uye kusina shaft kuneta.
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.
Zvakanakira zve trunnion bhora dhizaini ndiyo yakaderera yekushanda torque, kusununguka kwekushanda, kushomeka kwechigaro kupfeka (Stem / bhora kuparadzaniswa kunodzivirira kurodha kwepadivi uye kupfeka kwezvigaro zvepasi kunonatsiridza mashandiro uye hupenyu hwesevhisi), kuita chisimbiso chepamusoro pane zvese zvakakwirira uye zvakaderera (yakasiyana. Chitubu meshini uye kukwidza mutsara kudzvanywa kunoshandiswa sechisimbiso pakatarisana nebhora rakamira kune yakaderera kudzvanywa uye yakanyanya kudzvanywa maapplication).
Zvinhu zvikuru zveNORTECH Electric trunnion ball valve
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.
3.Emergency Seal Device
Mavharuvhu ebhora ane dhayamita kupfuura kana kuenzana ne6'(DN150) ese akagadzirwa aine sealant jekiseni mudziyo padzinde nechigaro.Kana rin'i yechigaro kana dzinde O ring yakuvadzwa nekuda kwetsaona, chisimbiso chinoenderana chinogona kubaiwa nejekiseni rejekiseni rekuvharisa kudzivirira kubvaruka kwepakati pamhete yechigaro uye dzinde.Kana zvichidikanwa, iyo yekubatsira yekuisa chisimbiso system inogona kushandiswa kugeza nekuzora chigaro kuti ichengetedze kuchena kwayo.
Sealant jekiseni mudziyo
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.
6.Reliable chigaro chisimbiso chimiro
Kuiswa chisimbiso kwechigaro kunoitwa kuburikidza nezvibatiso zviviri zvinoyangarara zvigaro, Zvinogona kuyangarara axially kuvhara mvura, kusanganisira kuvharika kwebhora uye kuiswa chisimbiso chemuviri. Iyo yakaderera kuisirwa chisimbiso chechigaro chevharuvhu inoonekwa nechirimo pre yakasimbiswa. rakagadzirwa nemazvo, rinoona kuvharika kwepamusoro nekudzvanywa kwepakati pachayo. Mhando mbiri dzinotevera dzekuvharisa bhora dzinogona kuitika.
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. .
8.Kuvhara kaviri (Piston mbiri)
Iyo trunnion pombi bhora vharafu inogona kugadzirwa nekaviri Chisimbiso chimiro pamberi uye mushure mebhora kune mamwe akakosha sevhisi mamiriro uye mushandisi zvinodiwa.Iine double piston effect.Mumamiriro ezvinhu akajairwa, vharuvhu inowanzotora chisimbiso chekutanga. Kana chigaro chekutanga chinotiisa chisimbiso chakanganiswa uye chichikonzera kudonha, chigaro chechipiri chinogona kuita basa rekuisa chisimbiso uye kuwedzera kuvimbika kwekusunga.chigaro chinotora chimiro chakabatanidzwa.Chisimbiso chekutanga isimbi kune chisimbiso chesimbi.Chisimbiso chechipiri chinonzi fluorine rubber O ring inokwanisa kuita kuti vharafu yebhora isvike pakuvharwa kwebubble level.Kana iyo yekudzvanyirira yakadzikira zvakanyanya, chigaro chekuisa chisimbiso chinodzvanya bhora kuburikidza nechirimo chiitiko kuti uone kuiswa chisimbiso chekutanga.Kana mutsauko wekumanikidzwa uchikwira, simba rekusimbisa rechigaro nemuviri rinowedzera zvinoenderana kuitira kuti usimbise zvakasimba chigaro nebhora uye kuve nechokwadi chekuisa chisimbiso chakanaka.
Chisimbiso chekutanga: Kumusoro.
Kana kudzvinyirirwa kunenge kwadzikira kana pasina kudzvanyirira kusiyanisa, chigaro chinoyangarara chinofamba axially pamwe nevharuvhu pasi pechitubu chiito uye pish chigaro chakananga kubhora kuti urambe wakasunga chisimbiso.Kana chigaro chevharuvhu chakwira kudarika simba rinoitwa panzvimbo A1, A2- A1=B1. Naizvozvo, simba riri muB1 rinosundira chigaro chakananga kuBhora uye kuona kuvharika kwakasimba kwechikamu chekumusoro.
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.
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
11.Blow-out Proof Stem
Dzinde rinotora maumbirwo euchapupu hwekuvhuvhuta. Dzinde rakagadzirwa rine chitsiko chetsoka kuzasi kwaro kuitira kuti kana paine chivharo chekumusoro kwekavha uye sikuruu, dzinde racho risapepererwe nepakati kunyange kana dzvinyiriro yakakwira mhango yevharuvhu.
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.
