(單作用,雙作用)進口氣動內(nèi)螺紋球閥由三片式球閥與氣動執(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，具有拆裝簡單維修方便等優(yōu)點(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
進口氣動內(nèi)螺紋球閥產(chǎn)品詳情 Product details
氣動內(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，可在遇到故障或沒有氣源時，自進口動歸位到開啟或關(guān)閉的狀態(tài)。氣動三片式球閥通過壓縮空氣為動力源，帶動閥芯做0-90度的來回轉(zhuǎn)動，即可實現(xiàn)對閥門的開關(guān)動作，在各個行業(yè)得到廣泛應(yīng)用，是常見的控制閥門 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
進口氣動內(nèi)螺紋球閥特點Characteristic進口氣動內(nèi)螺紋球閥3.jpg
1，采用三段式閥體，螺紋連接，結(jié)構(gòu)緊湊，重量輕，從高真空至高壓力都可應(yīng)用 Three section valve body, threaded connection, compact structure, light weight, applicable from high vacuum to high pressure
2，外形小巧，節(jié)約安裝空間，特別適用于機械體積小空間狹窄的工況當中 Compact shape, saving installation space, especially suitable for working conditions with small mechanical volume and narrow space
3，螺紋三片式氣動球閥密封可靠，使用壽命長，開關(guān)動作迅速，檢修起來方便，易拆裝 The threaded three piece pneumatic ball valve has reliable sealing, long service life, fast switching action, convenient maintenance and easy disassembly
