It is to be noted that the drawings are in a very simplified form and are all used in a non-precise ratio for the purpose of facilitating and distinctly aiding in the description of the embodiments of the invention.
As shown in fig. 1, the butterfly valve device of the present invention comprises a butterfly valve and a manual-hydraulic butterfly valve switch, wherein the manual-hydraulic butterfly valve switch is used for changing the opening and closing state of the butterfly valve.
As shown in fig. 1, in the present embodiment, the butterfly valve device includes a valve main body 8, a valve main shaft 7, and a butterfly plate 10 connected to the valve main shaft 7, wherein the butterfly plate 10 is a closing member of a butterfly valve, and is a disk-shaped structure in the present embodiment, and the butterfly valve is closed by rotating the butterfly plate 90 °. The valve main shaft 7 penetrates through the valve main body 8 and can rotate around the axis of the valve main shaft, and the valve main shaft 7 drives the butterfly plate 10 to rotate when rotating so as to change the opening and closing state of the butterfly valve. The manual hydraulic butterfly valve switch is connected with the valve spindle 7 and drives the valve spindle 7 to rotate, and then the opening and closing state of the butterfly valve is changed.
Optionally, the valve spindle 7 is connected to the butterfly plate 10 by a mechanical fastening device. In this embodiment, the mechanical fastening device is a taper pin 9, as shown in fig. 1, the valve spindle 7 and the butterfly plate 10 are connected by 3 taper pins 9 so as to be relatively fixed, and when the valve spindle 7 rotates, the butterfly plate 10 rotates together with the valve spindle. It should be understood that the connection between the valve spindle 7 and the butterfly plate 10 is not limited to the above, and in other embodiments, the connection may be other types of connection, which is not limited by the present invention.
As shown in fig. 1, a schematic diagram of a manual and hydraulic butterfly valve switch with a worm gear and a worm according to the present invention is shown, the manual and hydraulic butterfly valve switch includes a transmission main shaft 2 and a hydraulic actuator 1, the transmission main shaft 2 is connected to a valve main shaft 7 of a butterfly valve, an output end of the hydraulic actuator 1 is connected to the transmission main shaft 2 (the hydraulic actuator 1 is often connected to the transmission main shaft 2 through a rack and pinion), and the butterfly valve switch can achieve control of a butterfly valve switch state in a hydraulic drive mode. Under the hydraulic drive mode, the hydraulic actuator 1 drives the transmission main shaft 2 to rotate in a clockwise or anticlockwise rotation mode under the hydraulic action, and then drives the valve main shaft 7 of the butterfly valve to rotate so as to change the switching state of the butterfly valve, and control of the fluid flowing state in the pipeline is realized.
In practical applications, although hydraulic technology is more mature and the failure of the hydraulic device is rare, in some working environments, the hydraulic actuator 1 still inevitably has a failure condition. Consequently, for avoiding whole butterfly valve device's inefficacy, the manual butterfly valve switch that surges of this application still contains worm gear clutch 4, hand wheel 5 and conversion equipment 3. The switching device 3 is used for switching between a hydraulic driving mode and a manual driving mode of the butterfly valve switch. Under the hydraulic drive mode, the output end of the worm gear clutch 4 and the transmission main shaft 2 are in a separation state, and the hydraulic execution mechanism 1 is used for controlling the opening and closing state of the butterfly valve. In the manual driving mode, the output end of the worm gear clutch 4 is connected with the transmission main shaft 2, and the hand wheel 5 is connected with the worm gear clutch 4. The worm gear and worm clutch 4 transmits the kinetic energy of the rotation of the hand wheel 5 to the transmission main shaft 2 to enable the transmission main shaft 2 to rotate, and then the valve main shaft 7 of the butterfly valve is driven to rotate to change the opening and closing state of the butterfly valve, so that the control of the flowing state of fluid in the pipeline is realized. In this embodiment, the manual drive mode that worm gear clutch 4 and hand wheel 5 etc. of manual butterfly valve switch that surges realized can be used in emergency when the hydraulic drive mode became invalid, has increased manual drive promptly on the driven basis that surges, has further ensured the normal operating of butterfly valve.
In the present exemplary embodiment, the switching device 3 is a bypass valve, which is connected to the hydraulic actuator 1. When it is desired to switch from the hydraulic drive mode to the manual drive mode, the bypass valve is opened and brought into communication with the hydraulic actuator 1, the hydraulic actuator 1 and the bypass valve forming a fluid passage/circuit in which the fluid medium in the hydraulic actuator 1 circulates. When the bypass valve is closed and the hydraulic drive mode is switched, the fluid medium in the hydraulic actuator 1 is not circulated through the bypass valve, but rather is circulated through a different circuit, so that the hydraulic pressure of the hydraulic actuator 1 acts on the drive spindle 2. When the mode is converted into a manual driving mode, the bypass valve is opened, the worm gear clutch 4 is meshed with the top of the transmission main shaft 2, the hand wheel 5 is rotated to apply driving force to the hand wheel 5, the worm gear clutch 4 in contact with the hand wheel 5 transmits the rotational kinetic energy of the hand wheel 5 to the transmission main shaft 2 through the gear rack to rotate, the valve main shaft 7 of the butterfly valve is driven to rotate around the axis of the valve main shaft 7, and the state of the butterfly valve is changed by means of the butterfly plate 10.
Further, the worm gear clutch 4 and the hand wheel 5 are connected through a gear (both are always in a connected state), so that the worm gear clutch 4 can transmit kinetic energy.
Optionally, the rotation angle range of the transmission main shaft 2 is 0 to 90 degrees, the rotation angle range of the valve main shaft 7 connected with the transmission main shaft 2 is 0 to 90 degrees, and the rotation angle range of the butterfly plate 10 rotating along with the valve main shaft 7 is 0 to 90 degrees, so that the on-off control (when the rotation angle is 0 degree and 90 degrees) of the fluid in the pipeline and the control of the flow rate/flow rate of the fluid are realized by the butterfly valve.
As shown in fig. 1, in this embodiment, the hand wheel 5 is arranged horizontally, and both the hand wheel 5 and the worm gear clutch 4 are arranged above the hydraulic actuator 1 and the transmission main shaft 2, so as to apply a driving force to the hand wheel 5, and at the same time, the device drives the stressed transmission main shaft 2 closer to the butterfly valve, so that the transmission efficiency is higher. Of course, the arrangement positions of the hand wheel 5 and the worm gear clutch 4 are not limited to the above-mentioned scheme, and in other embodiments, the hand wheel and the worm gear clutch may also be arranged at other positions, and may be arranged according to actual requirements, which is not limited in this respect. Further, the arrangement direction of the hand wheel 5 is not limited, for example, for a valve with a lower installation position, the operation space for manually operating the valve can be improved by changing the placement direction of the hand wheel 5, so as to better apply acting force to the hand wheel 5. For example, as shown in fig. 2 and 3, in another embodiment, the handwheel 5 of the manual/hydraulic butterfly valve switch is arranged longitudinally, and the rotation direction is different from that of the present application, and in this embodiment, the arrangement of other components can be similar or identical to that of the present embodiment.
Based on the same invention concept, the invention also provides an operation method of the manual and hydraulic butterfly valve switch with the upper worm gear, which comprises the following steps: s1, a drive conversion device 3 is used for converting a hydraulic drive mode into a manual drive mode and connecting the output end of a worm gear clutch 4 with a transmission main shaft 2; s2, the hand wheel 5 is driven to rotate, and the worm gear clutch 4 transmits kinetic energy of the rotation of the hand wheel 5 to the transmission main shaft 2 so as to drive the valve main shaft 7 to rotate. It can be understood that, in practical application, the switching mode state of the butterfly valve is not limited to one, and needs to be switched according to practical application conditions, therefore, the present invention also provides an operation method of the aforementioned manual-hydraulic butterfly valve switch with the worm gear and the worm, the method comprising: t1, a drive conversion device 3 is used for converting a manual drive mode into a hydraulic drive mode and separating the output end of a worm gear clutch 4 from a transmission main shaft 2, namely, the worm gear clutch 4 is in the hydraulic drive mode; and T2, the hydraulic actuating mechanism 1 drives the transmission main shaft 2 to rotate so as to drive the valve main shaft 7 to rotate. In practical application, different switch driving modes can be adopted according to practical application requirements, and the invention is not limited to this. Further, the switching device 3 is a bypass valve. In step S1, the drive conversion device 3 opens the bypass valve, and simultaneously engages the worm gear clutch 4 with the top of the transmission spindle 2 to transmit kinetic energy. In step T1, the drive switching device 3 disengages the worm gear clutch 4 from the drive spindle 2 in order to close the bypass valve.
