簡(jiǎn)要描述:銷(xiāo)售日本SMC流量減壓閥,SMC減壓閥技術(shù) Precision pressure reducing valve, export pressure to not exceed 90% of the import pressure. is in the control of the gas control valve directly connected to a two thre
減壓閥的內(nèi)部受壓部分通常都是用膜片式結(jié)構(gòu),
2) Connect the piping to purge thoroughly.
3) The flow direction of the air is installed in the direction of the arrow and can not be installed.
4) the use of plastic materials, pressure relief valve, should avoid direct sunlight.
此時(shí),A口壓力為設(shè)定壓力。
當(dāng)A通口壓力上升,高于P1通口的壓力,
則F2>F1,調(diào)壓活塞上移,
上截止閥芯開(kāi)啟,A口與R口接通并排氣。當(dāng)
A口壓力下降F2=F1時(shí),又恢復(fù)原狀態(tài)。
大流量精密減壓閥有氣控型和手動(dòng)操作型以及外部導(dǎo)電磁型。
,其工作壽命比膜片式減壓閥長(zhǎng)。
故閥的開(kāi)口量小,輸出流量受限制。
VEX1系列減壓閥的受壓部分是用平衡座閥式閥芯,
可以得到很大的輸出流量和溢流流量,故稱(chēng)為大流量精密減壓閥。
The output pressure must not exceed the maximum value of the set pressure.
導(dǎo)壓力P1作用在調(diào)壓活塞上的力為F1,
A通口氣壓力經(jīng)反饋通道作用在調(diào)壓活塞下的力為F2.
當(dāng)F1=F2時(shí),一對(duì)截止閥芯處于封閉狀態(tài)。
因兩閥芯是對(duì)稱(chēng)結(jié)構(gòu),彈簧力使閥芯復(fù)位。
Port A and Port P are connected and supplied with gas. When the A port pressure rises to F2 = F1, it returns to its original state.
External pilot electromagnetic large flow precision pressure reducing valve
當(dāng)A通口壓力下降,高于P1通口的壓力,則F2
