氣動對焊 承插焊球閥
簡要描述:RETZ進口氣動對焊,承插焊球閥由三片式球閥與氣動執(zhí)行器連接組成,采用三段式結構,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 The imported pneumatic butt welding and socket welding ball valves are composed of a three piece ball valve and a pneumatic actuator. The three section structure is adopted, which is composed of a left and right valve bodies and a middle valve body, which are connected by bolts into a whole. It has the advantages of simple disassembly, simple maintenance, etc.

進口氣動對焊,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位功能,可在遇到故障或沒有氣源時,自動歸位到開啟或關閉的狀態(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)對閥門的開關動作,在各個行業(yè)得到廣泛應用,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
