2.兩閥座密封三通球閥具有結(jié)構(gòu)緊湊、外形美觀、密封性能好,它能實(shí)現(xiàn)對(duì)管道中介質(zhì)流向的切換。也能使相互垂直的兩個(gè)通道連通或關(guān)閉(如流向圖A)
3.四閥座密封三通球閥具有造型美觀、結(jié)構(gòu)緊湊合理,它不僅可實(shí)現(xiàn)介質(zhì)流向的切換,也可使三個(gè)通道相互連通,同時(shí)可關(guān)閉任意一個(gè)通道,使另外兩個(gè)通道連通,靈活控制管路是介質(zhì)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(zhì)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.
