[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment discloses a high platform ball valve, referring to Figure 1 , including valve bodies 1 and 2. The valve body 1 is provided with a transmission shaft 6 connected to the valve core of the valve body 1. The transmission shaft 6 is a polygonal column and is driven to rotate by the actuator 2. A lifting platform 3 is installed above the valve body 1. The lifting platform 3 is provided with a longitudinally arranged positioning structure 4. The actuator 2 is installed on the lifting platform 3 through the positioning structure 4, and the transmission shaft 6 is passed through the output shaft of the actuator 2.

[0025] Reference Figure 1 , 2 The positioning structure 4 includes a positioning groove 41, a positioning column 42 and a positioning pin 43. The positioning groove 41 is longitudinally spaced and arranged on the side wall of the lifting platform 3 close to the actuator 2; the positioning column 42 extends laterally and is fixed to the side wall of the actuator 2, and the positioning column 42 is passed through the positioning groove 41; the positioning pin 43 is longitudinally passed through and slides on the lifting platform 3, and the positioning pin 43 can be passed through the positioning groove 41 and plugged into the positioning column 42.

[0026] Reference Figure 1 , 3 The actuator 2 is supported by a supporting structure 5. The supporting structure 5 includes a supporting sleeve 51, a lifting column 52 and a plug-in block 53. The lifting column 52 extends longitudinally and is connected to the lifting platform 3 at both ends. The lifting columns 52 are arranged at intervals on both sides of the actuator 2; the lifting sleeve is sleeved on the lifting column 52, the height of the supporting sleeve 51 corresponds to the longitudinal arrangement of the positioning grooves 41, and a height of the lifting sleeve is left between the lifting sleeve and the lifting platform 3, and both ends of the supporting sleeve 51 are chamfered; the plug-in blocks 53 are respectively fixed on both sides of the actuator 2, and the plug-in blocks 53 are provided with a slope extending up and down at one end close to the lifting platform 3. The slopes separate adjacent supporting sleeves 51 through the chamfer of the support sleeve, the height of the plug-in block 53 corresponds to the lifting sleeve setting, and the plug-in block 53 has a gap for longitudinally sleeved lifting columns 52.

[0027] Reference Figure 1 , 3A clamping structure 7 is provided at the top of the lifting column 52, and the clamping structure 7 includes a clamping thread 71 and a clamping bolt 72. The clamping thread 71 is opened at the top of the lifting column 52, and the top of the lifting column 52 is penetrated through the top of the lifting platform 3; the clamping bolt 72 is screwed into the clamping thread 71 and abuts against the side of the lifting platform 3 relative to the supporting sleeve 51; when the plug-in block 53 is worn or a gap is generated between the supporting sleeve 51 due to thermal expansion and contraction, the stability of the positioning column 42 is improved by adjusting the clamping bolt 72.

[0028] The working process of the present application is as follows: adjust the height of the actuator 2, align the oblique surface of the plug-in block 53 on the actuator 2 with the chamfers of the two corresponding support sleeves 51, connect the plug-in block 53 in series with the positioning column 42, pull the positioning pin 43 upward so that the positioning column 42 can be inserted into the positioning groove 41, and the positioning pin 43 falls and is inserted into the positioning column 42. At this time, the plug-in block 53 is positioned longitudinally by the support sleeve 51 and horizontally by the positioning groove 41 and the positioning pin 43, thereby completing the three-axis positioning; at this time, the transmission shaft 6 is inserted into the actuator 2 and plugged into the valve body 1, and the connection between the actuator 2 and the valve body 1 is completed.
