Beschreibung
Zusammenfassung:	The invention provides a straight stroke composite block valve which comprises a valve body, a liquid inlet is formed in the bottom of the valve body, a valve rod is arranged in the valve body, a driving device is arranged at one end of the valve rod and used for driving the valve rod to move in a reciprocating mode so as to open or close the liquid inlet, a liquid outlet is formed in one side of the valve body, a ball is arranged in the valve body, and a liquid outlet is formed in the other side of the valve body. The valve rod is sleeved with the ball body, and an assembling structure is arranged between the ball body and the valve rod and used for driving the ball body to synchronously rotate along with movement of the valve rod so as to open or close the liquid outlet. According to the straight-stroke composite block valve, the linkage of the valve rod and the ball body is adopted to achieve the composite motion of two types of valves, only one driving device is needed in the whole process to meet the fun
