(單作用,雙作用)進(jìn)口氣動(dòng)內(nèi)螺紋球閥由三片式球閥與氣動(dòng)執(zhí)行器連接組成，采用三段式結(jié)構(gòu)，由左右兩片閥體與中間閥體組成，再用螺栓連接成一體，具有拆裝簡(jiǎn)單維修方便等優(yōu)點(diǎn)(Single acting, double acting) The imported pneumatic internal thread ball valve is composed of a three piece ball valve and a pneumatic actuator. It adopts a three-stage structure, consisting of left and right valve bodies and the middle valve body, which are connected by bolts into a whole. It has the advantages of simple disassembly and easy maintenance
進(jìn)口氣動(dòng)內(nèi)螺紋球閥產(chǎn)品詳情 Product details
氣動(dòng)內(nèi)螺紋球閥的作用形式分為雙作用和單作用，單作用形式具有彈簧復(fù)位功能，可在遇到故障或沒(méi)有氣源時(shí)，自進(jìn)口動(dòng)歸位到開(kāi)啟或關(guān)閉的狀態(tài)。氣動(dòng)三片式球閥通過(guò)壓縮空氣為動(dòng)力源，帶動(dòng)閥芯做0-90度的來(lái)回轉(zhuǎn)動(dòng)，即可實(shí)現(xiàn)對(duì)閥門(mén)的開(kāi)關(guān)動(dòng)作，在各個(gè)行業(yè)得到廣泛應(yīng)用，是常見(jiàn)的控制閥門(mén) RETZ The action forms of the imported pneumatic internal screw ball valve are divided into double action and single action. The single action form has the spring return function, which can automatically return to the open or closed state in case of failure or no air source. The pneumatic three piece ball valve uses compressed air as the power source to drive the valve core to rotate back and forth at 0-90 degrees, which can realize the opening and closing of the valve. It is widely used in various industries and is a common control valve
