Kif biex tikklassifika it-tipi ta ' pnewmatiċi solenoid valvi?

Fi il industrijali kontroll sistema , il solenojd valv jista ' jikkoopera ma differenti loops biex tikkontrolla il-fluss direzzjoni , fluss rata , veloċità u oħrajn parametri ta ' il- medju % 2c filwaqt li tiżgura l-eżattezza u flessibilità ta ' il- kontroll . Hemm ħafna tipi ta' solenoid valvi. differenti solenoid valvi play differenti rwoli f' pożizzjonijiet differenti ta ' il - kontroll sistema. Il most commonly użati huma unidirezzjonali valvi, safety valves, directional control valves, speed control valves, speed control valves and so on.

Pnewmatiku solenoid valvi huma ikklassifikati kif dirett pistun struttura, pass pass dirett pistun struttura u pilota pistun struttura.

Direct-acting solenoid valve: When electrified, the solenoid coil produces electromagnetic force, which lifts the closing part from the seat and opens the valve. When power is cut off, the electromagnetic force disappears and the spring presses the closing part on the sea of the valve. T, the valve is closed. It is characterized by normal operation under vacuum, negative pressure and zero pressure, but its diameter generally does not exceed 25 mm.

Distribwit dirett solenoid valve: Huwa a kombinazzjoni ta ' prinċipju dirett u pilota prinċipju. Meta hemm le pressjoni differenza bejn il - bokka u żbokk , il elettromanjetiċi forza direttament lifts il - pilota valv u il - main valve għeluq partijiet up in turn, u il valv jiftaħ. Meta il-bokka u il-ħruġ jilħaq il-bidu pressjoni differenza, il elettromanjetiku forza gwidi il ż-żgħar valv wara elettrifikazzjoni, il inqas kamra pressjoni ta' il main valve rises and the upper chamber pressure drops, so li the main valve is pushed ' il fuq by the pressure difference; after the power supply is cut off, the pilot valve uses spring force or medium pressure to push down the closing parts, so li il valv jagħlaq.

Pilota solenojd valve: When electrified, the electromagnetic force opens the pilot hole, the upper chamber pressure drops rapidly, forming a low-high pressure difference around the closing part, the fluid pressure pushes upward the closing part the closing part, and the valve opens. When the power is cut off, the spring force closes the guide hole, and the inlet pressure closes the combustion chamber quickly through the bypass hole. Baxx pressjoni differenza u għoli pressjoni differenza huma iffurmati madwar il valv . Fluwidu pressjoni timbotta ' l isfel il - shutoff valve u tagħlaq il- valv.

Il treġġigħ lura valve jinsab fi il - fuq ta ' il mekkaniku kontroll u industrijali valve. Kontrolli il- pożizzjoni ta' il- valv qalba permezz elettromanjetiċi kojl , gass sinjal u estern mekkaniku tagħbija forza , qatgħat off jew jgħaqqad l-arja sors għal bidla id-direzzjoni ta ' fluwidu fluss u kontroll id-direzzjoni ta' medju % 2c hekk biex tikseb il- ... meħtieġa kontroll.
