產(chǎn)品簡介

三通球閥是綜合技術而開發(fā)的新型三通切換型調節(jié)閥。標準球芯有L型三通雙口孔種,改變球芯與管道的相對角度,可以對三支管道流體實現(xiàn)不同的組合控制;T型孔道可起配比作用,適用于液休、氣體、蒸汽等介質的配比調節(jié)與控制。

詳細介紹

氣動三通球閥由GT型、DA型、AW型氣動活塞式雙作用或單作用(彈簧復位式)執(zhí)行機構組成,有比例調節(jié)型(采用電-氣閥門定位器,以電信號和壓縮空氣為動力,接受控制系統(tǒng)輸入的0-10mA DC或4-20mA DC電流信號,改變球芯的旋轉角度,可實現(xiàn)比例調節(jié)動作)。二位切換型(采用電磁換向閥、閥位回訊器,以AC220V或DC24V電源電壓和壓縮空氣作動力,實現(xiàn)對流體介質的快速切換控制)

Pneumatic ball valve by the GT model, DA type, AW pneumatic piston double acting or single acting (spring return) actuator composed of a proportional control type (use of electricity - gas valve positioner to electrical signals and compression air-powered, the control system receiving input 0-10mA DC or 4-20mA DC current signal, change the angle of rotation of the ball core can achieve proportional control action). Two switch-type (electromagnetic valve, valve back to the hearing to AC220V or DC24V power supply voltage and compressed air, the fluid medium to achieve fast switching control)

1.三通球閥有兩座和四座密封結構,閥芯孔道有L型和T型兩種結構形式,采用控制閥芯旋轉角度,改變閥芯孔道與管道口的連接狀態(tài),可實現(xiàn)對三條支管不同的組合控制。三通球閥流通能力大,可控制氣體、液體、蒸汽,更適用于控制高粘度,纖維顆粒狀的流體。也適用于密封要求較嚴格的場合。
2.兩閥座密封三通球閥具有結構緊湊、外形美觀、密封性能好,它能實現(xiàn)對管道中介質流向的切換。也能使相互垂直的兩個通道連通或關閉(如流向圖A)
3.四閥座密封三通球閥具有造型美觀、結構緊湊合理,它不僅可實現(xiàn)介質流向的切換,也可使三個通道相互連通,同時可關閉任意一個通道,使另外兩個通道連通,靈活控制管路是介質的合流或分流(如流向圖B)。
4.T型閥芯孔道可使三條正交的管道互相連通或切換,起分流或合流作用;L型孔道連接相互正交的兩管道。使另一條孔道切斷,起改變介質流向作用。
5.三通球閥的主要產(chǎn)品系列:如流向圖所示選擇工況;A圖L型、B圖T型(1-4)

1. There are two and four-way ball valve sealing structure, L-valve and T channels are two kinds of structure, the use of control spool rotation, change the channel and pipe spool port connection status, can achieve three different branch combination control. Ball valve flow capacity, can control the gas, liquid, vapor, but also for control of high viscosity, fiber granular fluid. Sealing requirements are more stringent for the occasion.
2. Two way ball valve seat sealing with compact structure, beautiful appearance, good sealing performance, it can achieve in the medium of the pipeline flow switch. Perpendicular to each other can also connect two channels on or off (such as the flow chart A)
3. Four-way ball valve with a valve seat sealing beautiful shape, compact structure, which not only enables media flow switch also allows three channels interconnected, and can close any channel, connected to the other two channels, flexible control pipeline is the media mixing or diverting service (such as the flow of Figure B).
4. T-valve allows three orthogonal channel pipes or switch connected to each other, from the confluence of diversion or the role; L-type channels to connect the two orthogonal channels. Another channel to cut off media flow from changes in the role.
5. Tee Ball's main product lines: the flow chart as shown in choice condition; A map L-type, B T-diagram (1-4)
