Embodiment Construction
[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0021] In the example, such as figure 1 , figure 2 , image 3 As shown, the butterfly valve hydraulic drive device includes a housing 1 and a top cover 2. An output shaft 3 connected to the butterfly valve is installed in the housing 1, and a shaft sleeve 4 is installed on the output shaft 3. On the shaft sleeve 4 A vane 5 is provided, and a cavity is provided in the housing 1, and the vane 5 divides the cavity into a first cavity 6 and a second cavity 7, and the top cover 2 is provided with a cavity communicating with the first cavity 6. The No. 1 oil inlet hole 8 and the No. 2 oil inlet hole 9 communicated with the No. 2 chamber 7, and the bottoms of the No. 1 chamber 6 and the No. 2 chamber 7 are provided with oil outlet holes 10 . By injecting hydraulic oil into the first cavity 6 or the second cavity 7, the hydraulic oil pushes the vane 5 to rotate s...

The invention provides a butterfly valve hydraulic driving device. The hydraulic driving device solves the problems that existing butterfly valve control equipment is complex in structure and larger in size. The hydraulic driving device is characterized by comprising a shell and a top cover, an output shaft connected with the butterfly valve is installed in the shell, a shaft sleeve is installed on the output shaft, a blade is arranged on the shaft sleeve, a cavity is formed in the shell, the blade divides the cavity into a first cavity and a second cavity, the top cover is provided with a first oil inlet hole communicated with the first cavity and a second oil inlet hole communicated with the second cavity, and oil outlet holes are formed at the bottom of the first cavity and the bottom of the second cavity. Hydraulic oil is introduced into the first cavity or the second cavity and pushes the blades to rotate so that the shaft sleeve can rotate, the shaft sleeve drives the output shaft to rotate so that a butterfly valve can be controlled to be opened or closed, the overall structure is simple, and meanwhile the size is small and torque is large.
Description
technical field [0001] The invention relates to the field of butterfly valve drive equipment, in particular to a butterfly valve hydraulic drive device. Background technique [0002] The existing butterfly valves are generally controlled directly by the power motor, and several gears with different diameters are set between the power motor and the rotary output shaft that controls the opening and closing of the butterfly valve, and the function of changing the speed and increasing the torsional force is completed through several gears. ; There are problems of complex structure and large volume through this control method. Contents of the invention [0003] In order to overcome the disadvantages of the background technology, the present invention provides a butterfly valve hydraulic drive device, which solves the problem of complicated structure and large volume of the current butterfly valve control equipment. [0004] The technical scheme that the present invention adopt...
