Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but embodiments of the present invention are not limited thereto.
As shown in fig. 1, a worm wheel opposite clamping type silencing butterfly valve is commonly used for controlling the flow of a medium in a pipe body on the pipe body. The butterfly valve comprises a valve body 1, a valve plate 2, a sealing ring 3, a valve rod 4, a driving structure 7 and a worm and gear structure 6, wherein a flow passage which is convenient for fluid to pass through is formed on the valve body, the flow passage is cylindrical, the valve plate 2 is positioned in the flow passage, and the sealing ring 3 is arranged between the valve body 1 and the valve plate 2 in order to ensure the tightness of the valve body when the fluid is not conveyed. The outside of valve body 1 wears to be equipped with valve rod 4, and the one end and the valve plate 2 fixed connection of valve rod 4, the other end of valve rod 4 are equipped with worm gear structure 6, and drive structure 7 and worm gear structure 6 drive connection.
When the driving structure 7 works, the worm and gear structure 6 plays a role in transmission, the valve rod 4 is driven to rotate, and the valve rod 4 drives the valve plate 2 to rotate relative to the sealing ring 3. When the side wall of the valve plate 2 is completely attached to the sealing ring 3, the valve plate 2 is in a closed state, and medium cannot circulate. When the valve plate 2 rotates 45 degrees relative to the sealing ring 3, the valve plate 2 is not attached to the sealing ring 3, the valve plate 2 is in a semi-open state, medium flows in the pipe body, and the flow is small. When the valve plate 2 rotates 90 degrees relative to the sealing ring 3, the valve plate 2 still does not fit with the sealing ring 3, and at the moment, the valve plate 2 is in a fully opened state, and the flow of the medium in the pipe body is maximum.
In the prior art, most butterfly valves can adopt a hand wheel as a power device for driving a worm gear and a worm to rotate, the larger the angle or the number of turns of the hand wheel is, the larger the angle of rotation of the valve plate 2 relative to the sealing ring 3 is, namely, the flow opening of a pipe body is gradually increased, and as the hand wheel is rotated to be manually operated, a worker cannot see the movement condition of the valve plate 2 in the valve body 1, and the valve plate 2 cannot be accurately controlled to realize the three states when the hand wheel is controlled to rotate. Therefore, in the present embodiment, the driving structure 7 includes the servo motor 71 and the rotary encoder 72, the rotary encoder 72 is coaxially disposed on the output shaft of the servo motor 71, and the rotary encoder 72 may be a photoelectric rotary encoder 72. By setting the servo motor 71, a worker can preset parameters such as the rotating speed, the rotating time, the rotating number of turns and the like of the motor to accurately control the motion mode of the output shaft of the servo motor 71.
If the servo motor 71 is set as a conventional unidirectional rotating motor, according to the three states of the valve plate 2, the servo motor 71 corresponds to two movement modes, and the valve plate 2 is in a closed state initially, at this time, the servo motor 71 does not need to move. When the servo motor 71 adopts the first movement mode, the valve plate 2 rotates by 45 degrees, and the valve plate 2 moves from the closed state to the half-open state or from the half-open state to the full-open state. When the servo motor 71 adopts the second movement mode, the valve plate 2 rotates by 90 °, and the valve plate 2 moves from the closed state to the fully opened state or from the fully opened state to the closed state. If the servomotor 71 is a forward and reverse rotation motor, the valve plate 2 is initially in a closed state according to the three states of the valve plate 2, and at this time, the servomotor 71 does not need to move. When the servo motor 71 adopts the first movement mode, the valve plate 2 rotates forward by 45 degrees, and the valve plate 2 moves from the closed state to the half-open state or from the half-open state to the full-open state. When the servo motor 71 adopts the second movement mode, the valve plate 2 rotates forward by 90 degrees, the valve plate 2 moves from the closed state to the fully opened state, and when the servo motor 71 adopts the third movement mode, the valve plate 2 rotates reversely by 90 degrees, and moves from the fully opened state to the closed state.
By providing the rotary encoder 72, according to photoelectric conversion, mechanical quantities such as angular displacement, angular velocity, direction and the like of the output shaft of the servo motor 71 can be converted into corresponding electric pulses, and output as digital quantities, positive and negative can be used for reflecting the forward and reverse directions of the servo motor 71, for example, when the servo motor 71 is a conventional unidirectional rotary motor, the larger the rotation angle of the servo motor 71 is, the larger the digital quantity of the electric pulses is, and whether the rotation angle of the servo motor 71 is the same at each operation can be distinguished from the difference between the two adjacent digital quantities. Thus, each digital quantity represents the movement mode of the servo motor 71 each time, and the digital quantity is different, and the movement mode is different, and the state of the valve plate 2 is different. The rotary encoder 72 is electrically connected to the peripheral background terminal so as to facilitate the display of digital quantities on the background terminal, which, after being summarized, may form a corresponding graphic or chart.
For some pipes, the operating condition of the valve plate 2 is different when the media to be transported are different, or the operating condition of the valve plate 2 is different when the media to be transported are the same but the flow rates required for the different operating times are different. Therefore, a worker can intuitively see the working state of the valve plate 2 from the graph, monitor the working of the pipe body and judge whether the medium flow of the pipe body is abnormal.
The butterfly valve further comprises a controller, the servo motor 71 is connected with the output of the controller, different buttons can be formed on the controller corresponding to the movement mode of the servo motor 71, the buttons are connected with the input of the controller, and when a worker remotely presses the buttons, the working state of the valve plate 2 can be easily and accurately controlled.
Because the valve plate 2 is shielded by the valve body 1 after the butterfly valve is arranged on the pipe body, when the servo motor 71 moves to drive the valve plate 2 to change the working state, the working state is invisible, and a worker cannot determine whether the valve plate 2 is in the correct working state. Therefore, the butterfly valve further comprises an angle checking structure, the angle checking structure is arranged between the valve plate 2 and the sealing ring 3, the angle checking structure comprises a closed state checking component 8, a half-open state checking component 9 and a full-open state checking component 10, and the closed state checking component 8, the half-open state checking component 9 and the full-open state checking component 10 are all electrically connected with the controller.

When the valve plate 2 is in a closed state, the valve plate 2 and the sealing ring 3 are coaxially arranged, and at the moment, the side wall of the valve plate 2 can be fully contacted with the inner wall of the sealing ring 3. In order to check whether the valve plate 2 is coaxially arranged with the sealing ring 3, the pressure sensors 81 are provided with an upper pressure limit value and a lower pressure limit value, the difference between the upper pressure limit value and the lower pressure limit value is set by a worker according to practical situations, the set difference is taken as a negligible interval, and when the pressure value of each pressure sensor 81 is within the range of the upper pressure limit value and the lower pressure limit value, the valve plate 2 can be fully contacted with the inner wall of the sealing ring 3 to be in a closed state. The pressure sensor 81 is connected with the controller input, converts the electrical signal into an electrical signal for the operator to check, and if the valve plate 2 is inclined relative to the inner wall of the sealing ring 3, the maximum difference between the pressure sensors 81 will exceed the set difference, so that the operator needs to reset the working parameters of the servo motor 71.
