*牌：RETZ瑞茨/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)口氣動(dòng)對(duì)焊，承插焊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，具有拆裝簡單維修方便等優(yōu)點(diǎn)retz Pneumatic butt welding and socket welding ball valve is composed of a three piece ball valve and a pneumatic actuator, which adopts a three-stage structure. It is composed of left and right valve bodies and middle valve bodies, which are connected together by bolts. It has the advantages of simple disassembly and easy maintenance
進(jìn)口氣動(dòng)焊接球閥產(chǎn)品詳情 Product details
氣動(dòng)對(duì)焊，承插焊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(shí)，自動(dòng)進(jìn)口進(jìn)口氣動(dòng)焊接球閥2.jpg歸位到開啟或關(guān)閉的狀態(tài)。氣動(dòng)三片式球閥通過壓縮空氣為動(dòng)力源，帶動(dòng)閥芯做0-90度的來回轉(zhuǎn)動(dòng)，即可實(shí)現(xiàn)對(duì)閥門的開關(guān)動(dòng)作，在各個(gè)行業(yè)得到廣泛應(yīng)用，是常見的控制閥門 RETZ The functions of imported pneumatic butt welding and socket welding ball valves are divided into double acting and single acting. The single acting form has the function of spring return, 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
特點(diǎn)Characteristic
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(jī)械體積小空間狹窄的工況當(dāng)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(dòng)球閥密封可靠，使用壽命長，開關(guān)動(dòng)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
