進(jìn)口一片式內(nèi)螺紋球閥產(chǎn)品概述：
進(jìn)口一片式內(nèi)螺紋球閥是由雙（單）作用氣動活塞式執(zhí)行器和內(nèi)螺紋（對焊式）球閥組成。其閥體可分為整體式、二段式、三段式。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，閥桿不會被沖擊。氣動活塞式執(zhí)行器采用低摩擦材料做成軸承套，缸體內(nèi)外表面經(jīng)硬質(zhì)陽極氧化防腐處理，大大提高了氣缸的使用壽命。本產(chǎn)品使用性能穩(wěn)定，廣泛的用于石化、冶金、電力、輕工、醫(yī)藥等工業(yè)部門。
Import a piece of internal thread ball valve product overview:
Imported within a thread ball valve is composed of double (single) acting pneumatic piston actuator and internal thread (welded ball valve). The valve body can be divided into integral type, two section type, and the three section type. Seat with elastic sealing structure, reliable sealing, easy to open and close. The stem seal downloading inverted structure, abnormal pressure of the valve chamber, valve stem will not be hit. The pneumatic piston actuator is made of low friction material, and the inner and outer surfaces of the cylinder body are treated by hard anodic oxidation, which greatly improves the service life of the cylinder. This product is stable, widely used in petrochemical, metallurgy, electric power, light industry, medicine and other industrial sectors.
進(jìn)口一片式內(nèi)螺紋球閥工作原理：
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(jìn)入A缸（B缸）推動活塞向一端運(yùn)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氣動閥門處在開啟位置，而紅燈亮?xí)r氣動閥門處在關(guān)閉位置。定位器可調(diào)節(jié)閥門管道流量。
Import a piece of internal thread ball valve working principle:
When the pneumatic actuator is connected with 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 is rotated 90 degrees, pneumatic actuator linkage device when the top visible, green signs point the word mark to open the valve open. A reply signal lamp lights the pneumatic valve is in the open position, the valve is in the closed position and the red light of aerodynamics. Positioner can adjust the valve pipe flow.
