Vharuvhu yeSimbi Yakapfava yeDuctile Vharuvhu yeSimbi Yakapfava yeDuctile Vharuvhu yeSimbi Yakapfava yeDuctile
Mavharuvhu egedhi reSoft Seal uye mavharuvhu egedhi reHardware anoshandiswa zvakanyanya kudzora nekudzivirira kuyerera kwemvura, ese ari maviri ane mashandiro akanaka ekuvharira, akasiyana-siyana ekushandisa, uye ndeimwe yezvigadzirwa zvinotengwa nevatengi vakawanda. Vamwe vanotanga kutenga vanogona kuda kuziva, zvakafanana nevharuvhu regedhi, musiyano uripo pakati pawo ndeupi?
Chisimbiso chakapfava chisimbiso pakati pesimbi neisiri simbi, nepo chisimbiso chakasimba chiri chisimbiso pakati pesimbi nesimbi. Vharuvhu yegedhi rechisimbiso chakapfava uye vharuvhu yegedhi rechisimbiso chakasimba zvinhu zvekusimbisa, chisimbiso chakasimba chinogadzirwa nemazvo nezvinhu zvechigaro kuti chive nechokwadi chekuti chinoenderana nespool (bhora), kazhinji simbi isina tsvina nemhangura. Chisimbiso chakapfava chakaiswa muvharuvhu. Chisimbiso chechigaro chevharuvhu chinhu chisiri simbi, nekuda kwekuti chinhu chekusimbisa chakapfava chine mwero wakati we elasticity, uye nekudaro zvinodiwa zvekugadzirisa zvakanyatsonaka zvakaderera pane zvichave chisimbiso chakasimba. Pasi apa tora kuti unzwisise musiyano uripo pakati pevharuvhu yegedhi rechisimbiso chakapfava nevharuvhu yegedhi rechisimbiso chakasimba.
Zvinhu zvekutanga zvekuvhara
1. Zvinhu zviviri zvekuvhara zvakasiyana. Vharuvhu yegedhi rekusimbisa rakapfava inowanzova rabha kana PTFE nezvimwe zvinhu. Vharuvhu yegedhi rekusimbisa rakaoma richishandisa simbi isina ngura nedzimwe simbi.
2. Chisimbiso chakapfava: kuvharira divi remativi maviri esimbi, rimwe divi rezvinhu zvisina simbi zvinopfava, zvinozivikanwa se "chisimbiso chakapfava". Kuvharira mavharuvhu egedhi akadaro, asi kwete tembiricha yakakwira, zviri nyore kupfeka, uye hunhu husina kunaka hwemakanika. Zvakadai sesimbi + rabha; simbi + PTFE nezvimwewo.
3. Chisimbiso chakasimba: chisimbiso chakasimba uye chisimbiso kumativi ese isimbi kana zvimwe zvinhu zvakasimba. Chisimbiso chevharuvhu chegedhi chakadaro hachina kunaka, asi chinodzivisa kupisa kwakanyanya, hachina kunaka, uye chine hunhu hwakanaka hwemakanika. Zvakadai sesimbi + simbi; simbi + mhangura; simbi + graphite; simbi + simbi ye alloy; (inogona zvakare kushandisa simbi yakakandwa, simbi ye alloy, alloy ye spray pendi, nezvimwewo).
Chechipiri, maitiro ekuvaka
Indasitiri yemakanika ine nzvimbo yakaoma yekushanda, yakawanda yacho ine tembiricha yakaderera uye kumanikidzwa kwakaderera, kuramba kushandiswa kwemidziyo yakawanda, uye ngura. Iye zvino, kufambira mberi kwetekinoroji kwakaita kuti mavharuvhu egedhi rezvisimbiso zvakaoma afadzirwe.
Kuti tifunge nezvehukama huripo pakati pekuoma kwesimbi, vharuvhu yegedhi rekusimbisa, uye kusimbaradzwa kwakapfava, muviri wevharuvhu unofanira kusimbiswa, uye plate yevharuvhu nechigaro chevharuvhu kuti zvirambe zvichikuya kuti zvisimbiswe. Kugadzirwa kwevharuvhu yegedhi rekusimbisa kwakareba.
Chechitatu, kushandiswa kwemamiriro ezvinhu
1, chisimbiso chakapfava chinogona kuita kuti pasave nekubuda kwemvura, chisimbiso chakaoma chinogona kugadziriswa zvichienderana nezvinodiwa nepamusoro nepasi;
2、Zvisimbiso zvakapfava zvinogona kudonhedza mvura kana tembiricha yakakwira, zvinofanirwa kutariswa kudzivirira moto, uye zvisimbiso zvakasimba hazvidonhedze mvura kana tembiricha yakakwira. Chisimbiso chakasimba chevharuvhu chinovhara nekukurumidza chinogona kushandiswa kana paine kumanikidzwa kwakanyanya, chisimbiso chakapfava hachigone kushandiswa.
3, kune mamwe ma media anoparadza, chisimbiso chakapfava hachigone kushandiswa, unogona kushandisa chisimbiso chakasimba;
4, kana tembiricha yakaderera zvakanyanya, zvinhu zvakapfava zvechisimbiso zvichabuda, chisimbiso chakasimba hachisi dambudziko rakadaro;
Chechina, kusarudzwa kwemidziyo kuri
Mazinga ese ari maviri ekuvhara anogona kusvika matanhatu, kazhinji zvichienderana nedanho rekushanda, tembiricha, uye kumanikidzwa kuti usarudze vharuvhu regedhi rakakodzera. Kune general media ine zvidimbu zvakasimba kana abrasive, kana kana tembiricha ikapfuura 200 degrees, zvakanaka kusarudza hard seal. Kana torque yevharuvhu yekudzima yakakura, unofanirwa kusarudza kushandisa hard seal gate valve.
Chishanu, musiyano muhupenyu hwebasa
Chakanakira chisimbiso chakapfava ndechekusunga zvakanaka, dambudziko nderekuti chiri nyore kukwegura, kusakara, hupenyu hupfupi. Hupenyu hwebasa rekusunga zvakasimba hwakareba, uye mashandiro ekusunga akaipa kupfuura kusunga zvinyoro, zviviri izvi zvinogona kubatsirana.
Zviri pamusoro apa musiyano uripo pakati pe soft seal gate valve ne hard seal gate valve kugovana ruzivo, ndinotarisira kuti ndikwanise kukubatsirai pabasa rekutenga.
