Cov yam ntxwv ntawm cov dej ntws ntawm lub valve thiab kev faib tawm ntawm cov yam ntxwv ntawm cov dej ntws ntawm lub valve, qhov sib txawv ntawm qhov siab thiab qhov qhib ntawm lub valve ntawm ob qho kawg yog qhov ruaj khov, qhov nruab nrab ntws los ntawm lub valve thiab nws qhov qhib yog qhov sib raug zoo ntawm cov yam ntxwv ntawm cov dej ntws ntawm lub valve yog ib qho tseem ceeb ntawm cov cim qhia thiab cov kev cai hauv cov txheej txheem thov valve kom ua qhov kev xaiv raug muaj qhov tseem ceeb heev.

Tus yam ntxwv ntawm cov dej ntws ntawm lub valve tuaj yeem txhais tau tias yog: qhov ntws sib piv ntawm cov khoom tswj hwm los ntawm lub valve, thiab kev sib raug zoo ntawm qhov qhib sib piv (kev hloov chaw sib piv) ntawm lub valve thiab lub valve hu ua tus yam ntxwv ntws ntawm lub valve tswj hwm. Feem ntau hais lus, nws muab faib ua plaub hom: kab ncaj, feem pua ​​sib npaug (logarithm), parabola thiab qhib sai! Cov lus piav qhia tshwj xeeb thiab qhov zoo yog raws li nram no:

Ua ntej, tus cwj pwm linear yog hais txog kev sib raug zoo ntawm tus nqi ntws ntawm lub valve thiab qhov qhib sib raug zoo, uas yog, qhov tsis tu ncua ntawm kev hloov pauv ntawm kev ntws los ntawm kev hloov pauv ntawm qhov qhib chav. Kev mus ncig ntawm cov yam ntxwv linear yog nyob rau hauv kev sib raug zoo ntawm txoj kab ncaj nraim nrog tus nqi ntws sib raug zoo. Kev hloov pauv ntawm tus nqi ntws los ntawm kev hloov pauv ntawm chav stroke yog tas li. Thaum tus nqi ntws loj, tus nqi sib raug zoo ntawm tus nqi ntws hloov me me, thiab tus nqi ntws me me, tus nqi sib raug zoo ntawm tus nqi ntws hloov ntau heev.

Qhov thib ob, qhov sib npaug ntawm feem pua ​​(logarithm) txhais tau hais tias qhov kev hloov pauv ntawm cov dej ntws los ntawm kev hloov pauv ntawm qhov qhib ntawm chav tsev yog sib npaug rau qhov nrawm ntawm qhov taw tes, uas yog, qhov coefficient ntawm lub valve tswj kev hloov pauv, thiab nws nce nrog qhov nce ntawm qhov nrawm. Qhov sib piv ntawm stroke thiab qhov nrawm ntawm cov yam ntxwv sib npaug ntawm feem pua ​​tsis nyob hauv kev sib raug zoo, thiab qhov kev hloov pauv ntawm cov dej ntws los ntawm kev hloov pauv ntawm chav tsev ntawm txhua qhov taw tes ntawm qhov stroke yog sib npaug rau qhov nrawm ntawm qhov no, thiab feem pua ​​ntawm kev hloov pauv ntawm cov dej ntws yog sib npaug. Yog li ntawd, nws qhov zoo yog tias qhov nrawm me me, qhov hloov pauv ntawm cov dej ntws yog me me, thiab thaum qhov nrawm loj, qhov nrawm hloov pauv ntau heev, uas yog, nws muaj qhov tseeb kho tib yam hauv qhov qhib sib txawv.

Qhov thib peb, tus yam ntxwv parabolic yog hais txog qhov kev hloov pauv ntawm cov dej ntws los ntawm kev hloov pauv ntawm qhov qhib ntawm lub unit hauv qhov sib piv ncaj qha rau cov hauv paus plaub fab ntawm tus nqi ntws sib piv ntawm qhov no. Tus nqi ntws sib txawv raws li ob sab ntawm lub stroke, nrog rau cov yam ntxwv nruab nrab ntawm cov yam ntxwv linear thiab sib npaug zos.

Plaub, qhov qhib ceev ceev yog hais txog qhov ntws loj dua thaum qhov qhib me me, nrog rau qhov nce ntawm qhov qhib, qhov nrawm ntws tuaj yeem ncav cuag qhov siab tshaj plaws, thiab tom qab ntawd nce qhov qhib, qhov hloov pauv ntws me me heev, yog li nws hu ua qhov qhib ceev ceev.

Cov yam ntxwv ntawm kev ntws ntawm cov diaphragm li qub yog ze rau cov yam ntxwv qhib sai, cov yam ntxwv ntawm kev ntws ntawm cov npauj npaim li qub yog ze rau qhov sib npaug ntawm feem pua, cov yam ntxwv ntawm kev ntws ntawm cov qhov rooj li qub yog cov yam ntxwv linear, cov yam ntxwv ntawm kev ntws ntawm cov pob li qub yog cov kab ncaj nraim hauv qhov qhib thiab kaw nruab nrab, thiab cov yam ntxwv ntawm feem pua ​​sib npaug hauv qhov qhib nruab nrab.

Feem ntau, cov pob li qub thiabnpauj npaim li qubFeem ntau tsis siv rau kev kho kom haum, yog tias siv rau kev kho kom haum, tab sis kuj yog qhov qhib me me ua lub luag haujlwm hauv kev tswj hwm, feem ntau tuaj yeem raug cais ua hom qhib sai, thiab qhov tseeb yog kev tswj hwm ntawm feem ntau ntawm lub ntiaj teb valve yooj yim, lub taub hau valve ua tiav rau hauv xws li parabolic cone, spherical, thiab lwm yam, yuav siv cov yam ntxwv sib txawv, feem ntau siv ua kev kho kom haum, feem ntau yog feem pua ​​ntawm cov yam ntxwv siv ntau dua.
