I-ESDV-Emergency Valve Yokuvala

ipharamitha yokusebenza

Ivalvu yokusika yomoya isebenzisa isakhiwo sokuvala esithambile, esakhelwe ukuvala okusebenzayo nokugcina, nge-torque encane yokusebenza, isilinganiso sokucindezela kokuvala esimaphakathi, ukuvala okuthembekile, isenzo esibucayi, ukulawulwa okulula kwe-hydraulic ukuze kufezwe ukulawula okuzenzakalelayo, kanye nokuphila isikhathi eside kwenkonzo. Amavalvu ebhola okusika omoya asetshenziswa kabanzi ezimbonini ezifana ne-petroleum, amakhemikhali, i-metallurgy, ukwenza amaphepha, imithi, i-electroplating, njll.

Amapharamitha okusebenza kwe-valve yokuvala umoya:

1. Ingcindezi yokusebenza: 1.6Mpa kuya ku-42.0Mpa;

2. Izinga lokushisa lokusebenza: -196+650 ℃;

3. Izindlela zokushayela: ngesandla, igiya lezikelemu, umoya, kagesi;

4. Izindlela zokuxhuma: intambo yangaphakathi, intambo yangaphandle, i-flange, ukushisela, ukushisela izinqe, ukushisela amasokhethi, umkhono, i-clamp;

5. Izindinganiso zokukhiqiza: I-JB 、 HG 、 i-American standard API ANSI ， i-British Standard BS, i-Japanese JIS JPI, njll.;

6. Izinto zomzimba we-valve: ithusi, insimbi ephonswe, insimbi ephonswe, insimbi yekhabhoni i-WCB、WC6、WC9、20#、25#、 Insimbi eyakhiwe i-A105、F11、F22、 Insimbi engagqwali, 304, 304L, 316, 316L, insimbi ye-chromium molybdenum, insimbi ephansi lokushisa, insimbi ye-titanium alloy, njll.

I-valve yokusika i-pneumatic isebenzisa uhlobo lwefoloko, uhlobo lwe-rack yegiya, uhlobo lwe-piston, kanye nama-actuator omoya omoya ohlobo lwe-diaphragm, ane-double acting kanye ne-single acting (ukubuya kwentwasahlobo).

1. I-piston ephindwe kabili yohlobo lwegiya, ene-torque enkulu yokukhipha kanye nevolumu encane;

2. Isilinda senziwe ngezinto ze-aluminium, ezilula futhi ezibukeka kahle;

3. Izindlela zokusebenza ngesandla zingafakwa phezulu nangaphansi;

4. Ukuxhumeka kwe-rack kanye ne-pinion kungalungisa i-engeli yokuvula kanye nesilinganiso sokugeleza okulinganiselwe;

5. Isibonakaliso sempendulo yesignali ebukhoma ongayikhetha kanye nezesekeli ezahlukahlukene zama-actuator ukuze kufezwe ukusebenza okuzenzakalelayo;

6 Uxhumano olujwayelekile lwe-IS05211 lunikeza lula ukufakwa nokufakwa komkhiqizo;

7. Izikulufo ezilungisekayo kuzo zombili izinhlangothi zivumela imikhiqizo ejwayelekile ukuthi ibe nobubanzi obulungisekayo obungu-± 4 ° phakathi kuka-0 ° no-90 °. Qinisekisa ukunemba kokuvumelanisa nevalvu.
