性能描述SMC直動式3通氣控閥/集裝用

特點作用:

氣(qi)(qi)動控制閥(fa)(fa)是指在氣(qi)(qi)動系(xi)統中控制氣(qi)(qi)流(liu)的(de)壓力、流(liu)量(liang)和流(liu)動方向(xiang)，并保證氣(qi)(qi)動執(zhi)行元(yuan)(yuan)件或(huo)機構正常(chang)工作的(de)各類氣(qi)(qi)動元(yuan)(yuan)件。控制和調節壓縮(suo)空氣(qi)(qi)壓力的(de)元(yuan)(yuan)件稱(cheng)為(wei)壓力控制閥(fa)(fa)。控制和調節壓縮(suo)空氣(qi)(qi)流(liu)量(liang)的(de)元(yuan)(yuan)件稱(cheng)為(wei)流(liu)量(liang)控制閥(fa)(fa)。改變和控制氣(qi)(qi)流(liu)流(liu)動方向(xiang)的(de)元(yuan)(yuan)件稱(cheng)為(wei)方向(xiang)控制閥(fa)(fa)。

還有能(neng)(neng)實現一定邏輯(ji)(ji)功(gong)能(neng)(neng)的邏輯(ji)(ji)元(yuan)(yuan)件(jian)，包括(kuo)元(yuan)(yuan)件(jian)內部(bu)無可動部(bu)件(jian)的射流元(yuan)(yuan)件(jian)和(he)有可動部(bu)件(jian)的氣(qi)動邏輯(ji)(ji)元(yuan)(yuan)件(jian)。在(zai)結構原理上(shang)，邏輯(ji)(ji)元(yuan)(yuan)件(jian)基本上(shang)和(he)方向控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)相同，僅僅是體積(ji)和(he)通徑較小，一般用來實現信(xin)號的邏輯(ji)(ji)運算(suan)功(gong)能(neng)(neng)。隨(sui)著(zhu)氣(qi)動元(yuan)(yuan)件(jian)的小型化(hua)以(yi)(yi)及PLC控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)在(zai)氣(qi)動系(xi)統(tong)中(zhong)的大量應(ying)(ying)用，氣(qi)動邏輯(ji)(ji)元(yuan)(yuan)件(jian)的應(ying)(ying)用范圍正在(zai)逐漸減小。從控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)方式來分，氣(qi)動控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)可分為(wei)斷續(xu)(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)連(lian)續(xu)(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)兩類(lei)。在(zai)斷續(xu)(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)中(zhong)，通常要用壓力控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)、流量控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)和(he)方向控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)來實現程(cheng)序動作;連(lian)續(xu)(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)中(zhong)，除(chu)了要用壓力、流量控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)外(wai)，還要采用伺服、比例控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)等，以(yi)(yi)便對系(xi)統(tong)進行連(lian)續(xu)(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。

氣(qi)控閥的(de)混(hun)合出(chu)水(shui)(shui)口(kou)處，裝有一個(ge)熱(re)敏元件(jian)，利用感溫(wen)(wen)(wen)(wen)(wen)原件(jian)的(de)特(te)性推動閥體內閥芯移動，封(feng)堵或者(zhe)開啟(qi)冷(leng)、熱(re)水(shui)(shui)的(de)進水(shui)(shui)口(kou)。在封(feng)堵冷(leng)水(shui)(shui)的(de)同(tong)時開啟(qi)熱(re)水(shui)(shui)，當溫(wen)(wen)(wen)(wen)(wen)度(du)(du)調(diao)節旋鈕設(she)定(ding)某一溫(wen)(wen)(wen)(wen)(wen)度(du)(du)后，不論冷(leng)、熱(re)水(shui)(shui)進水(shui)(shui)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)、壓力(li)如(ru)何變化(hua)，進入出(chu)水(shui)(shui)口(kou)的(de)冷(leng)、熱(re)水(shui)(shui)比例也隨之變化(hua)，從而使(shi)出(chu)水(shui)(shui)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)始終保持恒(heng)定(ding)，調(diao)溫(wen)(wen)(wen)(wen)(wen)旋鈕可在產品規定(ding)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)范圍內任意設(she)定(ding)，恒(heng)溫(wen)(wen)(wen)(wen)(wen)混(hun)水(shui)(shui)閥將自動維(wei)持出(chu)水(shui)(shui)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)。
