Uyini umehluko phakathi kwe- 4 2 kanye nama-valves 5 2

umgomo wokuhlukanisa phakathi4/2 no-5/2 ama-pneumatic valvesAmanga ngaphakathi kwamachweba ahlukahlukene kanye nezindlela abasebenzisa ngazo ukuqhuma komoya kugajethi ye-pneumatic. Nakhu ukwephulwa komehluko:

1. Ubungako bamachweba:

4/2 Valve:

Inamachweba amane nezikhundla ezi-2.

Amachweba ngokuvamile ahlukaniswe njenge:

P (ingcindezi): Ixhunywe ekunikezelweni komoya okucindezelwe.

A no-B: Sebenzisa amachweba, ahlobene nabasebenzayo (isib. Ama-Cylinders).

Ukuphelelwa amandla: I-Vent Port yomoya onzima.

I-WAFT iqondiswe futhi ivela ku-actuator (noma ithuluzi elawulwa), futhi i-valve ilawula indlela ye-airflow ku-actuator.

5/2 Valve:

Inamachweba ama-5 nezikhundla ezi-2.

Amachweba ajwayele ukuhlukaniswa njengoba:

P (ukucindezela): Kuxhunyaniswe ekunikezelweni komoya okucindezelwe.

A no-B: Sebenzisa amachweba, axhunyaniswe nabasebenzayo (isib. Ama-Cylinders).

Amachweba Oqeda Amachweba: Imvamisa amachweba angu-2 aqedeka (evame ukuhlukaniswa njenge-EA ne-EB) ukukhipha umoya wokuqeda ngenkathi i-valve ihamba.

2. Ukusebenza:

4/2 Valve:

Ngokuyisisekelo esetshenziselwa izinhlelo ezilula lapho kulawulwa khona umshuwalense owodwa (njenge-cylinder) ezinkomba (ukukhulisa / ukubuyisa).

Lezi zikhundla zombili zizokwenza konke:

Xhuma imbobo ye-P ethekwini (umoya ungene ku-actuator).

Xhuma imbobo ye-P echwebeni (umoya ungene ohlangothini oluphambene lwe-actuator).

Ukuphelelwa yisikhathi: Kunamanje embonini eyodwa yokuphelelwa amandla ekhipha umoya endaweni ezungezile ngenkathi umoya uguqulwe ngaphakathi noma uphume ku-actuator.

5/2 Valve:

Okuningi okuguquguqukayo ukwedlula i-valve engu-4/2, njengoba kusetshenziswa kakhulu emaphaketheni adinga amachweba amabili awohloka (okwengeziwe okuvame ukusetshenziswa nge-Double - enza ama-cylinder).

I-valve engu-5/2 iqondisa ukuhamba ngendiza kunoma iyiphi imbobo noma i-port b ngenkathi futhi idlulisela amachweba ahlukile wokuqeda amandla kuyo yonke indlela.

Amachweba Oqeda Amachweba: Amachweba ahlukile awohloka (e-EA evamile ne-EB) asetshenziswa, avumela ukuqeda umoya olawulwayo kusuka ezingxenyeni ngasinye ze-actuator.

3. Sebenzisa izimo:

4/2 Valve:

Imvamisa esetshenziselwa imisebenzi elula lapho asikho isidingo samachweba ahlukile awodwa.

Kumnandi ukulawula i- - nge-cylinder noma izimo lapho kudingeka khona umzila owodwa wokuqeda amandla.

5/2 Valve:

Imvamisa esetshenziselwa ukukhohlisa kabili - yenza amasilinda amasilinda, lapho amachweba afisela khona yonke indlela yokunyakaza (eyodwa ohlangothini ngalunye lwe-piston).

Kusetshenziswe ezinhlelweni eziyinkimbinkimbi ezengeziwe lapho kubalulekile ukulawula uhlangothi lokuphetha khona ngokulawula ukuqondiswa komoya nosizi.

ezine. Ukulawula Ukuphekela:

I-4/2 VALVE: ngokuvamile inechweba eli-1 lokuqeda.

I-5/2 Valve: Inamachweba angu-2 aqedela, okunikeza ukulawula okwengeziwe ngaphezulu kwe-glide eqeda amandla futhi kuwusizo kumaphakeji adinga ukulawulwa okuphezulu kokuntanta noma kabili - avela amasilinda.

I-5. I-PRICE YOKUZIPHATHA:

Ngakho-ke,5/2 valvengokuvamile kuthuthuke kakhulu, kunikeza ukuphathwa okuhlukile kokuphekela phansi kanye nokuguquguquka okungeziwe kokulawula kabili - amasilinda asebenzayo, ngenkathi4/2 valveIlula futhi ilungele izinhlelo zokusebenza eziyinkimbinkimbi.
