三通球阀 THREE BALL VALVE
【产品用途】
三通球阀有T型和L型。T型能使三条正交的管道相互联通和切断第三条通道，起分流、合流作用。L型只能连接相互正交的两条管道，不能同时保持第三条管道的相互连通，只起分配作用
【Usage】
Ball valve with T-and L-type. T-make three interconnected orthogonal channels and cut off the third channel, divert traffic, merge function. L-only connection between the two orthogonal channels can not simultaneously maintain a third pipe connected with each other, only as a distribution function
【产品特点】
1、三通球阀在结构上采用一体化结构，4面阀座的密封型式，法兰联接少，可靠性高，设计实现了轻量化
2、三通球芯分T型和L型，使用寿命长，流通能力大，阻力小
3、球阀按作用式分单作用和双作用两种型式，单作用式的特点是一旦动力源发生故障时，球阀将处于控制系统要求的状态
【Features】
1, ball valve structure used in the integrated structure, 4-valve seat sealing surface type, small flange connection, high reliability, design and implement lightweight
2, three T-ball core points and L-type, long life, flow capacity, small resistance
3, ball by acting the role of sub-single-and dual role of two types, single-action features, once sources of power failure, a ball will be in control of the state of the system requirements
