Umgaqo wokusebenza kunye nemodi yokulawula i-valve ezenzekelayo

Ivalve ezenzekelayo luhlobo lwevalvu olunokuthi lulungelelanise ngokuzenzekelayo ukuhamba, uxinzelelo, ubushushu kunye nezinye iiparamitha ngokuhambelana notshintsho lweparameters yenkqubo, esetyenziswa kakhulu kwi-petroleum, ishishini lemichiza, isinyithi, ukwakhiwa kunye namanye amashishini. Eli phepha liza kuhlalutya umgaqo wokusebenza kunye nemodi yokulawula i-valve ezenzekelayo kwiinkalo ezimbini.

Okokuqala, umgaqo wokusebenza
Umgaqo wokusebenza wevalve ezenzekelayo ubukhulu becala kusetyenziswa inzwa yokubona utshintsho lweeparamitha zenkqubo, isiginali efunyenweyo idluliselwa kwi-actuator, i-actuator ilungisa ukuvulwa kwevalve ngokomqondiso, ukuze kufezekiswe uhlengahlengiso oluzenzekelayo lokuhamba. , uxinzelelo, ubushushu kunye nezinye iiparamitha.

I-Sensor ye-1: I-sensor sisixhobo esiguqula ubuninzi bomzimba obuhlukeneyo kwinkqubo (efana nobushushu, uxinzelelo, ukuhamba, njl.) kwiimpawu zombane. Izinzwa eziqhelekileyo zi-thermocouples, i-resistors ye-thermal, i-pressure sensors, i-flow sensors kunye nokunye.

2. I-Actuator: I-actuator sisixhobo esiguqula imiqondiso yombane ibe yintshukumo yomatshini kwaye isetyenziselwa ukulungisa ukuvuleka kwevalve. Ii-activators eziqhelekileyo zi-activators zombane, ii-pneumatic actuators, ii-hydraulic actuators njalo njalo.

3. I-valve: I-valve sisixhobo esilawula ukuhamba, uxinzelelo, ubushushu kunye nezinye iiparamitha ze-fluid medium. Iivalve eziqhelekileyo ziivalve zeglowubhu, iivalve ezilawulayo, iivalve zokhuseleko, iivalve zokunciphisa uxinzelelo njalo njalo.

2. Imo yokulawula
Iindlela zokulawula iivalvu ezizenzekelayo ikakhulu ngolu hlobo lulandelayo:
1. Ulawulo lokuvula: Ngokutshintsha ukuvulwa kwe-valve, lungisa ukuhamba, uxinzelelo, ubushushu kunye nezinye iiparitha ze-fluid medium. Iindlela zokulawula ukuvulwa eziqhelekileyo ziquka ulawulo lokuvula ngesandla, ulawulo lokuvula umbane, ulawulo lokuvula umoya kunye nokunye.

2. Ukulawulwa kwe-Bit: ukuvulwa kwe-valve kulawulwa kwindawo echanekileyo yokulawula ukuhamba, uxinzelelo, ubushushu kunye nezinye iiparitha ze-fluid medium. Iindlela zokulawula bit eqhelekileyo ziquka ulawulo bit manual, ulawulo bit yombane, ulawulo bit womoya njalo njalo.

3. Ukulawulwa kokulungelelaniswa: Ngokulungelelanisa ukuvulwa kwe-valve, ukuhamba, uxinzelelo, ubushushu kunye nezinye iiparitha ze-fluid medium zingalungiswa ngokuqhubekayo. Iindlela zolawulo eziqhelekileyo zibandakanya ulawulo lwe-proportional integral-differential (PID), ulawulo olungaqondakaliyo, ulawulo lwe-neural network njalo njalo.

4. Ulawulo olukrelekrele: Ngokusebenzisa itekhnoloji yobukrelekrele bokwenziwa, ukufikelela kulawulo olukrelekrele lweevalvu ezizenzekelayo. Iindlela eziqhelekileyo zokulawula iingqondo ziquka inkqubo yeengcali, i-algorithm yemfuza, inethiwekhi ye-neural eyenziweyo njalo njalo.

Ukushwankathela, umgaqo osebenzayo wevalve ezenzekelayo kukubona utshintsho kwiiparamitha zenkqubo ngokusebenzisa inzwa, ukuhambisa umqondiso ofunyenweyo kwi-actuator, kwaye i-actuator ilungisa ukuvulwa kwevalve ngokomqondiso, ukuze iqonde i-automatic. ukulungiswa kokuhamba, uxinzelelo, ubushushu kunye nezinye iiparamitha. Iindlela zokulawula iivalvu ezizenzekelayo zibandakanya ulawulo lokuvula, ulawulo lwe-bit, ulawulo lohlengahlengiso kunye nolawulo oluhlakaniphile, njl. Ezi ndlela zokulawula zinokuhlangabezana neemfuno zokulawula iivalve ezizenzekelayo phantsi kweemeko ezahlukeneyo zokusebenza.
