進(jìn)口電動(dòng)內(nèi)螺紋三通球閥 絲口電動(dòng)三通球閥

品牌:retz瑞茨/我們一直致力于流體控制和測(cè)控領(lǐng)域的持續(xù)創(chuàng)新,始于2005……
進(jìn)口電動(dòng)內(nèi)螺紋三通球閥有兩座和四座密封結(jié)構(gòu),閥芯孔道有l(wèi)型和t型兩種結(jié)構(gòu)形式,采用控制閥芯旋轉(zhuǎn)角度,改變閥芯孔道與管道口的連接狀態(tài),可實(shí)現(xiàn)對(duì)三條支管不同的組合控制
retz the imported electric internal thread three-way ball valve has two and four sealing structures, and the valve core port has two types of structure: l-shaped and t-shaped. by controlling the rotation angle of the valve core and changing the connection state between the valve core port and the pipeline port, different combinations of three branch pipes can be controlled
功能介紹 function introduction
進(jìn)口電動(dòng)內(nèi)螺紋三通球閥配置角行程電動(dòng)執(zhí)行機(jī)構(gòu),以ac220v、ac380v或dc24v電源電壓作動(dòng)力,接受工業(yè)自動(dòng)化儀表控制系統(tǒng)輸入的(4-20ma、或1-5vdc)電流信號(hào)或電壓信號(hào),即可控制運(yùn)轉(zhuǎn)retz the imported electric internal thread three-way ball valve is equipped with an angular stroke electric actuator, which is powered by ac220v, ac380v or dc24v power supply voltage and receives (4-20ma, or 1-5vdc) current signal or voltage signal input from the industrial automation instrument control system to control the operation
l型流道的三通4面閥座球閥,采用2面閥座,受力平衡,保證閉止通道的可靠密封。主要用于流路的換向 three-way four-side valve seat ball valve with l-shaped flow passage adopts two-side valve seat, with balanced stress, to ensure reliable sealing of the closing channel. mainly used for commutation of flow path
t型流道的三通4面閥座,由于采用4面閥座,亞力平衡,保證閉止通道的可靠密封。主要用于分流、混 流、換向以及三通道的完全開放 the three-way four-face valve seat of the t-shaped flow passage is balanced by yali due to the four-face valve seat, which ensures the reliable sealing of the closing channel. it is mainly used for shunt, mixed flow, commutation and full opening of three channels
