產(chǎn)品特點：

進口氣動三片式內(nèi)螺紋球閥及對焊連接球閥分為整體式(一片式)、兩段式及三段式。閥體鑄造，*工藝，結(jié)構(gòu)合理、造型美觀。閥座采用彈性密封結(jié)構(gòu)，密封可靠，啟閉輕松。 閥桿采用有倒密封的下裝式結(jié)構(gòu)，閥腔異常升壓時，閥桿不會被沖出。二片式、三片式球閥連接形式另有對焊承插焊，并均可帶支架平臺和鎖定裝置。可設(shè)置90°開關(guān)定位機構(gòu)，根據(jù)需要加鎖以防止誤操作，驅(qū)動方式:手動、電動、氣動。

Imported pneumatic three piece internal thread ball valve features:

Imported pneumatic three ball screw thread ball valve and welded connections into the integral (one piece), two segment and three segment. Body casting, advanced technology, reasonable structure, beautiful appearance. Seat with elastic sealing structure, reliable sealing, easy to open and close. The stem seal downloading inverted structure, abnormal pressure of the valve chamber, the stem will not be out. Two piece, three piece ball valve connection form another butt welding socket welding, and can support with a platform and locking device. The 90 degree switch positioning mechanism can be provided, and the lock can be prevented according to the need to prevent misoperation.

工作原理：

進口氣動三片式內(nèi)螺紋球閥當(dāng)氣動執(zhí)行器與電路和系統(tǒng)氣源接通后，空氣通過管道A或B管進入A缸（B缸）推動活塞向一端運動，從而帶動旋轉(zhuǎn)軸和球芯轉(zhuǎn)動90°。氣動執(zhí)行器頂部連動可視器，當(dāng)綠色標(biāo)志指向“開”字時標(biāo)志閥門開啟?；匦牌餍盘枱艟G燈亮?xí)r閥門處在開啟位置，而紅燈亮?xí)r閥門處在關(guān)閉位置。配定位器可調(diào)節(jié)閥門管道流量。

Imported pneumatic three piece internal thread ball valve working principle:

Imported pneumatic three ball valve when the pneumatic actuator is connected to the circuit and system of gas supply, air enters the cylinder through the A pipeline A or B tube (B cylinder) to push the piston to the end of movement, so as to drive the rotary shaft and the ball core rotates 90 degrees. Pneumatic actuator linkage device when the top visible, green signs pointing to the "open" word mark valve open. When the green light is on, the valve is in the open position and the valve is in the closed position when the red light is on. With positioner can adjust the valve pipe flow.
