【產品用途】
三通球閥有T型和L型。T型能使三條正交的管道相互聯通和切斷第三條通道，起分流、合流作用。L型只能連接相互正交的兩條管道，不能同時保持第三條管道的相互連通，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
【產品特點】
1、三通球閥在結構上采用一體化結構，4面閥座的密封型式，法蘭聯接少，可靠性高，設計實現了輕量化
2、三通球芯分T型和L型，使用壽命長，流通能力大，阻力小
3、球閥按作用式分單作用和雙作用兩種型式，單作用式的特點是一旦動力源發生故障時，球閥將處于控制系統要求的狀態
【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
