Gedhi reGedhi reGedha dzinowanzo tarisa kune yakaomeswa gedhi mavharuvhu. Chinyorwa ichi chinoongorora zvakadzama musiyano uripo pakati peGedhi rakapfava-suwo remagedhi nemavanga akajairika. Kana iwe uchigutsikana nemhinduro, ndapota ipa vton a zvigunwe kumusoro.
Zvichitaurwa zvakangoitika, suwo rakapfava dzakasungwa zvisimbiso uye simbi, dzakadai saNylon \ tetrafluorooro mukandiru, uye suwo rakaisvonaka rakashongedzwa zvisimbiso pakati pesimbi nesimbi;
Soft-sealed gate valves and hard-sealed gate valves refer to the sealing materials of the valve seat. Zvisungo zvakaoma zvakanyatsogadzirwa neValve Zvigadzirwa zvekushandisa kuti uve nechokwadi chekufananidza neValve Core (bhora), kazhinji simbi yesimbi uye mhangura. Soft seals refer to the sealing materials embedded in the valve seat as non-metallic materials. Because soft seal materials have a certain elasticity, the processing accuracy requirements are relatively lower than hard seals. Isu tinoreva hunhu hweVTON kurondedzera musiyano pakati pegedhi rakapetwa rakapfava rakapfava mavharuvhu uye dzinotanga kuiswa suwo rakaomeswa.
Akapfava-akasungwa suwo mavharuvhuzvinowanzogadzirwa nerabha kana polytetrafluorolene. Gedhi rakaomeswa rakaomeswa rakagadzirwa nesimbi dzakadai sesimbi isina tsvina.
2. Chisimbiso chakapfava: Chisimbiso chigadzika chakagadzirwa nezvinhu zvesimbi kune rimwe divi uye elastic isiri-simbi zvinyorwa kune rumwe rutivi, runonzi "chisimbiso chakapfava". Rudzi urwu rwechisimbiso ine basa rakanaka rekuisa chisimbiso, asi harisi kuramba tembiricha yakanyanya, nyore kupfeka, uye ine midziyo yakaipa yemakaniki. For example: steel rubber; simbi tetrafluorohyle, etc. semuenzaniso, iyo inotumirwa kunze kweiyo selastic chigaro chisimbisoE yeVTON inowanzo shandiswa pakupisa isingasviki 100 ℃, uye inonyanya kushandiswa kune yemhepo tembiricha mvura.
3. Chisimbiso chakaoma: iyo seal chiefa yakagadzirwa nezvinhu zvesimbi kana zvimwe zvigadzirwa zvakaomarara pamativi ese, izvo zvinonzi "chisungo chakaoma". Rudzi urwu rwechisimbiso ine musimboti wemisimbiso wekuisa chisimbiso, asi zvinopesana nekudziya kwakanyanya, kupfeka uye zvine michina yakanaka michina. For example: steel steel; steel copper; steel graphite; Simbi Alloy Simbi; . For example, the imported stainless steel gate valve of VTON can be used for steam, gas, oil and water, etc.
2. Tekinoroji yekuvaka
Nzvimbo yemishinari yemishinari yemichina yakaoma, yakawanda yeiyo Ultra-yakaderera tembiricha uye kumanikidzwa kwakaderera, nekudzikisira kukuru uye kukanganisa kwakasimba kwesvikiro. Now the technology has improved, so that hard-sealed gate valves have been widely promoted.
Hukama hutsinye pakati pesimbi hunofanirwa kuitirwa. Muchokwadi, iyo yakaomesesa gedhi revali yakaenzana neiyo yakapfava-yakasungwa yakasungwa nekuti ichi chisimbiso pakati pesimbi. Muviri wemuvhari unodikanwa kuti uome, uye ndiro yevharo uye chigaro cheumbi chinofanira kunge chiri chichienderera mberi kuti chisimbiswe chisimbiso. Kutenderera kwekugadzira kwegedhi rakaomarara-suwo rakareba.
3. Shandisa mamiriro
Kuisa chisimbiso zvisimbiso zvinyoro zvinogona kuzadzisa Zero Leroge, nepo zvisimbiso zvakaoma zvinogona kuve zvakakwirira kana zvakaderera zvinoenderana nezvinodiwa;
Zvipenga zvinyoro zvinyoro zvinoda kupisa moto, uye kubhururuka kuchaitika pakupisa kukuru, nepo zvisimbiso zvakaoma hazvizoregi. Emergency vharira-kubva kuvharanda zvigaro zvisimbiso zvakaoma zvinogona kushandiswa pasi pekumanikidzwa kwepamusoro, nepo zvisimbiso zvakapfava hazvigone kushandiswa. At this time, VTON's hard-sealed gate valve is needed.
Zvisimbiso zvinyoro hazvifanirwe kushandiswa pane zvimwe zvinokanganisa media, uye zvisimbiso zvakaoma zvinogona kushandiswa;
4. Kushanda mamiriro
Zvisimbiso zvakaoma zvinogona kuve zvakakwirira kana zvakaderera zvinoenderana nezvinodiwa; soft seals must be fireproof, and soft seals can achieve high individual seals. Because at ultra-low temperatures, soft seals will leak, while hard seals do not have this problem; hard seals can generally withstand very high pressures, while soft seals cannot. For example, the imported forged steel gate valves of VTON use hard seals, and the pressure can reach 32Mpa or 2500LB; soft seals cannot be used in some places due to the flow of the medium, such as some corrosive media); finally, hard seal valves are generally more expensive than soft seals. Kana zviri zvekuvakwa, musiyano uripo pakati pezviviri hazvisi zvikuru, musiyano mukuru chigaro cheValve, chisimbiso chakapfava hachina-simbi, uye chisimbiso chakaoma chesimbi
Gedhi Valvesinonyanya kuve yakavakirwa pachiitiko chepakati, tembiricha uye kumanikidzwa. Generally, if the medium contains solid particles or has wear or the temperature is higher than 200 degrees, it is best to use hard seals. Semuenzaniso, yakakwira-tembiricha yakakwira kazhinji inotenderera 180-350】, saka nzvimbo yakaoma yeSuodhi yeGedhi yeGedhi inofanira kusarudzwa.
Gedhi Valvesare much more expensive than imported soft-sealed gate valves; for example, VTON's DN100 imported cast steel gate valve is 40% more expensive than DN100 imported cast steel soft-sealed gate valve; Kana ese ari maviri akaomarara-akasungwa masuwo egedhi uye akapfava masuwo ekucherechedzwa pasi pemamiriro ekushanda, paunenge uchifunga nezvemutengo, edza kusarudza Gate yakapfava-isina kuchena.
7. Kusiyanisa muhupenyu hwebasa
Chisimbiso chakapfava chinoreva kuti rumwe rutivi rwevaridzi chiisana chakagadzirwa nezvinhu zvine kuderera kwakaderera. Kazhinji, kazhinji chigaro chechigaro chakapfava chakagadzirwa neisiri-simbi zvigadzirwa zvine mamwe simba, kuomesa uye kupisa kupisa. It has good sealing performance and can achieve zero leakage, but its life and adaptability to temperature are relatively poor. Zvishandiso zvakaoma zvakagadzirwa nesimbi uye zvine hutano husina kurongeka, kunyangwe vamwe vagadziri vanoti ivo vanogona kuzadzisa zero lage.
Kubodzwa kwezvisikwa zvakapfava kwakanaka kuisimbisa kuita, uye kusagadzikana kuri nyore kuchembera, kupfeka uye kubvarura, uye hupenyu hupfupi hwebasa. Zvisimbiso zvakaoma zvine hupenyu hwakareba hwebasa, asi kuita kwavo kwemusimbiso kwakanyatsoenzaniswa kwakaenzaniswa nezvisimbiso zvakapfava. Aya marudzi maviri ezvisimbiso anogona kuwirirana. Panyaya yekuisa chisimbiso, zvisimbiso zvakapfava zviri nani zvikuru, asi zvino chisimbiso chezvisikwa zvakaoma zvinogona zvakare kusangana nezvinodiwa zvinowirirana.
Zvisikwa zvinyoro-nyoro hazvigone kuzadzisa maitiro ezvekushandisa kune zvimwe zvinhu zvinokosheswa, asi zvisimbiso zvakaoma zvinogona kugadzirisa dambudziko iri!
These two types of seals can complement each other. Panyaya yekuisa chisimbiso, zvisimbiso zvinyoro zviri nani zviri nani, asi zvino chisimbiso chezvisikwa zvakaoma zvinogona zvakare kusangana nezvinodiwa zvinowirirana!
Zvisimbiso zvakaoma zvine hupenyu hwakareba hwebasa, asi chisimbiso chine zvakaipa kupfuura zvisimbiso zvakapfava.
