Yog hais tias qhov kev txwv hloov ntawm cov zis ncej yog tsis tsim nyog (qhov txwv hloov ua ntxov dhau), nws yuav cuam tshuam rau kev kho mob stroke. Yog li ntawd, ua ntej qhov tso zis ncej yog hloov kho, txhawm rau tiv thaiv qhov kev txwv hloov ntawm kev ua haujlwm ntxov dhau, kho cov ntsia hlau ntawm qhov txwv cam yuav tsum tau xoob kom ncua qhov kev txiav txim ntawm qhov txwv hloov.
Thaum qhov xwm txheej hloov mus rau "lub xeev ua haujlwm zoo", (uas yog, raws li lub tswv yim teeb liab txo qis, cov zis ncej txav mus rau sab saud), lub teeb liab tawm tswv yim maj mam txo. Thaum lub teeb liab tawm tswv yim nyob rau hauv thaj tsam ntawm 3.7mA ~ 3.95mA, kho thiab zawm lub cam sab nraud kom ua rau qhov kev txwv kev hloov pauv thiab cov zis ncej nres txav mus. Thaum qhov xwm txheej hloov mus rau qhov "rov qab ua haujlwm xeev", (uas yog, raws li lub tswv yim teeb liab nce, cov zis ncej txav mus rau sab saud), lub teeb liab input maj mam nce. Thaum lub teeb liab tawm tswv yim yog nyob rau hauv thaj tsam ntawm 20.2mA ~ 20.5mA, kho thiab nruj rau sab nraud txwv cam kom ua rau qhov kev txwv hloov ua thiab cov zis tso zis nres txav mus.

Feem ntau siv cov khoom siv hauv lub valve yog SUS304, SUS316, SUS316L, SUS410, SUS420, thiab lwm yam, thiab ua tiav raws li cov dej sib txawv. Txhawm rau tswj cov kua dej cavitation, cov kua dej uas muaj cov khoom muaj zog, thiab cov xwm txheej kub thiab kub siab, lawv yuav tsum tau ua kom tawv. kev kho mob kom ntev lub neej kev pab cuam ntawm lub valve.
Kev kho cua sov
a.304/316 khoom kho mob
Cov khoom siv no yog austenitic stainless hlau thiab feem ntau yog siv rau hauv kev ua haujlwm uas qhov nruab nrab yog corrosive lossis nyob rau hauv qhov kub thiab txias. Thaum qhov nruab nrab yog corrosive heev, kev kho yuav tsum tau nqa tawm. Lub hom phiaj ntawm kev kho tshuaj yog los txhim kho cov hardness thiab corrosion kuj ntawm cov khoom. Qhov kub thiab txias -196 ~ 530 degree
b.410/420 quenching thiab tempering kho (quenching + tempering) Cov khoom ntawm no series yog martensitic stainless hlau, uas yog ib qho zoo heev cavitation-resistant khoom. Nws yuav tsum tau quenched thiab tempered thaum siv nyob rau hauv high-temperature thiab high-pressure sib txawv. Lub hom phiaj ntawm quenching thiab tempering kev kho mob yog los txhim kho cov hardness ntawm cov khoom thiab ua kom nws lub neej kev pab nyob rau hauv hnyav ua hauj lwm tej yam kev mob. Qhov kub thiab txias -45 ~ 425 degree
c.17-4PH nag lossis daus hardening kev kho mob sib txawv thiab ntau npaum li cas ntawm ntxiv dag zog rau cov tshuaj muaj pes tsawg leeg ntawm stainless hlau, thiab ntau hom thiab ntau npaum ntawm carbides, nitrides, carbides thiab intermetallic compounds yog precipitated los ntawm cov nag lossis daus hardening txheej txheem, uas tsis tsuas yog txhim kho lub zog ntawm cov hlau tab sis tswj kom muaj zog txaus. Ib hom high-strength stainless hlau, hu ua nag lossis daus hardening. Qhov kub thiab txias -45 ~ 425 degree
Kev kho deg hardening
Kev kho cua sov saum npoo yog muab faib ua ob pawg: nto quenching thiab deg tshuaj kho cua sov. a. Nplaim cua sov nto quenching, tiv tauj hluav taws xob cua sov nto quenching, induction cua sov nto quenching, thiab lwm yam b.
