Description

Technical Field

[0001] This application relates to the field of mechanical valve assembly technology, and more particularly to manual / automatic pressure regulating valve assemblies. Background Technology

[0002] Pressure reducing valve assemblies are devices used in blast furnace gas pipeline systems to regulate the pressure of the medium in the pipeline. The pressure reducing valve assembly is connected to the gas pipeline via flanges, and by adjusting the opening of the valve assembly, the gas flow rate in the pipeline is adjusted, thereby regulating the pipeline pressure.

[0003] Existing pressure regulating valve assemblies consist of multiple butterfly valves. The butterfly valve's disc is driven by an electric or pneumatic device to rotate around the valve shaft, adjusting the disc's opening and thus regulating the amount of gas flowing through the pipeline, thereby adjusting the pipeline pressure. However, when the motor or cylinder of the electric or pneumatic device ages and fails due to prolonged use, the device will no longer apply force to the disc to maintain its opening within the pipeline. In this case, the gas in the pipeline will impact the disc, increasing its opening and causing the gas flow through the pipeline to become uncontrolled. Utility Model Content

[0022] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0023] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] refer to Figures 1 to 5 A preferred embodiment of the manual / automatic pressure regulating valve assembly according to this application will be described in detail below, wherein the manual / automatic pressure regulating valve assembly includes at least one pipe body 10, at least one manual on / off component 20 and at least one automatic on / off component 30.

[0026] Specifically, the tube 10 forms a medium channel 101 for the passage of a medium.

[0027] The manual on / off assembly 20 includes a manual valve body 21, a manual rotary valve stem 22, an operating element 23, and a manual butterfly plate 24. The manual valve body 21 is disposed within the pipe body 10. The manual rotary valve stem 22 passes through the manual valve body 21, and its extension direction extends along the diameter direction of the axial section of the pipe body 10, passing through the axis of the medium channel 101. The operating element 23 is disposed at one end of the manual rotary valve stem 22 to drive it to rotate. The manual butterfly plate 24 is disposed within the manual rotary valve stem 22 so as to be driven by the manual rotary valve stem 22 and rotate within the medium channel 101. The diameter direction of the manual butterfly plate 24 corresponds to the diameter direction of the axial section of the pipe body 10, so that when the manual butterfly plate 24 is rotated by the manual rotary valve stem 22, the on / off state of the medium channel 101 is adjusted by the manual butterfly plate 24, thereby controlling the flow rate of the medium within the medium channel 101.

[0028] The automatic on / off assembly 30 includes an automatic valve body 31, an automatic rotary valve stem 32, a drive member 33, and an automatic butterfly plate 34. The automatic valve body 31 is disposed within the pipe body 10. The automatic rotary valve stem 32 passes through the automatic valve body 31, and its extension direction extends along the diameter direction of the axial section of the pipe body 10, passing through the axis of the medium channel 101. The drive member 33 is disposed at one end of the automatic rotary valve stem 32 to drive it to rotate. The automatic butterfly plate 34 is connected to the automatic rotary valve stem 32 so that it can be driven by the automatic rotary valve stem 32 and rotate within the medium channel 101. The diameter direction of the automatic butterfly plate 34 corresponds to the diameter direction of the axial section of the pipe body 10, so that when the automatic butterfly plate 34 is driven to rotate by the automatic rotary valve stem 32, the on / off state of the medium channel 101 is adjusted by the automatic butterfly plate 34, thereby controlling the flow rate of the medium within the medium channel 101.

[0029] Preferably, the control element 23 is implemented as a handwheel.

[0030] Preferably, the drive element 33 is implemented in a manner including but not limited to electric motors and cylinders.

[0031] It should be noted that, in this embodiment, both the manual rotary valve stem 22 and the automatic rotary valve stem 32 are divided into two sections. The two opposing ends of the two manual rotary valve stem sections 22 pass through the manual valve body 21, while the two adjacent ends of the two manual rotary valve stem sections 22 are respectively disposed on the manual butterfly plate 24. Similarly, the two opposing ends of the two automatic rotary valve stem sections 32 pass through the automatic valve body 31, while the two adjacent ends of the two automatic rotary valve stem sections 32 are respectively disposed on the automatic butterfly plate 34.

[0032] As an example, when the surfaces of the manual butterfly plate 24 and the automatic butterfly plate 34 are both perpendicular to the axial direction of the pipe body 10, the medium will not be able to pass smoothly through the medium channel 101, and the manual / automatic integrated pressure regulating valve assembly is in a blocked state. Conversely, when the surfaces of the manual butterfly plate 24 and the automatic butterfly plate 34 are both parallel to the axial direction of the pipe body 10, the medium will be able to pass smoothly through the medium channel 101, and the manual / automatic integrated pressure regulating valve assembly is in a connected state.

[0033] By adjusting the rotation angle of the manual butterfly plate 24 and the automatic butterfly plate 34 relative to the axial direction of the pipe body 10 within the medium channel 101, the purpose of controlling the medium flow rate within the medium channel 101 can be achieved through the manual butterfly plate 24 and the automatic butterfly plate 34.

[0034] It is worth mentioning that, since both the manual butterfly plate 24 and the automatic butterfly plate 34 are disposed within the medium channel 101 to regulate the medium flow rate within the medium channel 101, when the drive member 33 of the automatic on / off assembly 30 is damaged due to prolonged use, preventing the drive member 33 from driving the automatic butterfly plate 34 to maintain a predetermined rotation angle via the automatic rotary valve stem 32, the manual butterfly plate 24 can be used to control the manual rotary valve stem 22 to rotate the manual butterfly plate 24 to regulate the medium flow rate within the medium channel 101. This improves the fault tolerance of the manual / automatic integrated pressure regulating valve assembly during use and reduces the possibility of the medium flow rate within the medium channel 101 being unable to be regulated due to damage to the drive member 33.

[0035] Meanwhile, since both the manual butterfly plate 24 and the automatic butterfly plate 34 are located within the medium channel 101, the flow rate of the medium within the medium channel 101 is determined by the rotation angle of the manual butterfly plate 24 and the automatic butterfly plate 34 relative to the axial direction of the tube body 10 within the medium channel 101. Therefore, the flow rate of the medium within the medium channel 101 can be adjusted more precisely.

[0036] Preferably, when the planes on which the surfaces of the manual butterfly plate 24 and the automatic butterfly plate 34 lie are perpendicular to the axial direction of the pipe body 10, the manual butterfly plate 24 and the automatic butterfly plate 34 are respectively press-fitted with the inner walls of the manual valve body 21 and the automatic valve body 31 of the medium channel 101 to prevent the medium from passing over the manual butterfly plate 24 or the automatic butterfly plate 34.

[0037] In this embodiment, the manual butterfly plate 24 and the automatic butterfly plate 34 rotate in the same direction within the medium channel 101. Alternatively, the manual butterfly plate 24 and the automatic butterfly plate 34 rotate in opposite directions within the medium channel 101.

[0038] Preferably, the manual / automatic pressure regulating valve assembly further includes multiple connecting members 40. Some of the connecting members 40 pass through the manual rotary valve stem 22 and the manual butterfly plate 24, while other connecting members 40 pass through the automatic rotary valve stem 32 and the automatic butterfly plate 34, thereby connecting the manual rotary valve stem 22 to the manual butterfly plate 24 and the automatic rotary valve stem 32 to the automatic butterfly plate 34 via the multiple connecting members 40.

[0039] Preferably, the connector 40 is implemented to include a cylindrical pin.

[0040] Preferably, the manual / automatic pressure regulating valve assembly further includes two pairs of valve stem shafts 50. The two pairs of valve stem shafts 50 are respectively sleeved on the opposite ends of the manual rotary valve stem 22 and the opposite ends of the automatic rotary valve stem 32, so as to improve the smoothness of rotation of the manual rotary valve stem 22 and the automatic rotary valve stem 32 through the two pairs of valve stem shafts 50.

[0041] Preferably, the manual on / off assembly 20 further includes at least one first sealing member 25. The first sealing member 25 is disposed between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24, so as to improve the sealing between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24 when the manual-automatic pressure regulating valve assembly is in the blocked state, thereby preventing the medium from passing through the manual butterfly plate 24.

[0042] In this embodiment, the first sealing member 25 includes at least one first sealing ring 251 and at least one first pressure ring 252. The first sealing ring 251 is fixed to the inner wall of the manual valve body 21 of the medium channel 101 by the first pressure ring 252.

[0043] As an example, when the control member 23 controls the manual butterfly plate 24 to rotate within the medium channel 101 via the manual rotary valve stem 22, and the plane containing the surface of the manual butterfly plate 24 is perpendicular to the axial direction of the pipe body 10, the outer periphery of the manual butterfly plate 24 presses against the first sealing ring 251 to improve the sealing between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24, preventing the medium in the medium channel 101 from passing over the manual butterfly plate 24.

[0044] In another modified embodiment, the first sealing member 25 includes at least one first sealing ring 251 and at least one first pressure ring 252. The first sealing ring 251 is fixed to the outer periphery of the manual disc 24 by the first pressure ring 252.

[0045] As an example, when the control member 23 controls the manual butterfly plate 24 to rotate within the medium channel 101 via the manual rotary valve stem 22, and the plane containing the surface of the manual butterfly plate 24 is perpendicular to the axial direction of the pipe body 10, the inner wall of the manual valve body 21 of the medium channel 101 presses against the first sealing ring 251 to improve the sealing between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24, preventing the medium in the medium channel 101 from passing over the manual butterfly plate 24.

[0046] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the example is given by taking the first sealing member 25 as including at least one first sealing ring 251 and at least one first pressure ring member 252, wherein the first sealing ring 251 is fixed to the inner wall of the manual valve body 21 of the medium channel 101 by the first pressure ring member 252.

[0047] Specifically, in this embodiment, a number of screws are used to sequentially pass through the first pressure ring 252, the first sealing ring 251 and the manual valve body 21 to fix the first sealing ring 251 to the inner wall of the manual valve body 21 of the medium channel 101.

[0048] Preferably, the first pressure ring 252 is implemented to include a pressure block.

[0049] The first sealing ring 251 is made of rubber so that it can elastically deform when compressed to fill the gap between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24, thereby improving the sealing performance between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24.

[0050] Preferably, multiple first sealing rings 251 and multiple first pressure rings 252 are implemented, and the multiple first pressure rings 252 correspond to the multiple first sealing rings 251. Multiple first sealing rings 251 are arranged end-to-end on the inner wall of the manual valve body 21 of the medium channel 101, and each first sealing ring 251 is fixed to the inner wall of the manual valve body 21 of the medium channel 101 by a first pressure ring 252. This allows for maintenance by replacing worn parts of the first sealing rings 251 when they wear out due to prolonged use. Compared to replacing all of the first sealing rings 251 as a whole, this method reduces the cost of replacing the first sealing rings 251.

[0051] Preferably, the manual on / off assembly 20 further includes a locking member 26. The locking member 26 is disposed between the manual rotary valve stem 22 and the control member 23. The locking member 26 is used to prevent the manual disc 24 from shaking due to the medium flowing in the medium channel 101 when the manual disc 24 is rotated to a predetermined angle.

[0052] Preferably, the locking member 26 is implemented as a worm gear mechanism.

[0053] As an example, since the locking member 26 has a self-locking capability, when the control member 23 controls the manual butterfly plate 24 to rotate to a predetermined angle through the locking member 26 and the manual rotary valve stem 22, and the medium flowing in the medium channel 101 impacts the manual butterfly plate 24, the locking member 26 can lock the position of the manual butterfly plate 24 through the manual rotary valve stem 22 to prevent the manual butterfly plate 24 from shaking due to being driven by the medium flowing in the medium channel 101. There is no need to manually support the control member 23 to stabilize the position of the manual butterfly plate 24 after it has rotated to the predetermined position, thus making the operation more convenient.

[0054] Preferably, the manual on / off assembly 20 further includes a manual filler 27. The manual filler 27 is fitted onto the end of the manual rotary valve stem 22 near the control member 23. The manual filler 27 is located at the end of the valve stem shaft 50 away from the manual butterfly plate 24, and between the manual rotary valve stem 22 and the manual valve body 21. This prevents the medium in the medium channel 101 from flowing out through the gap between the valve stem shaft 50 and the manual valve body 21, and also prevents external dust from adhering to the valve stem shaft 50 and causing damage. Furthermore, the obstruction provided by the manual filler 27 prevents the valve stem shaft 50 from slipping off the surface of the manual rotary valve stem 22, ensuring the valve stem shaft 50 functions stably.

[0055] Preferably, the manual filler 27 is made of rubber.

[0056] Preferably, the manual on / off assembly 20 further includes a manual packing plate 28. The manual packing plate 28 is connected to the manual valve body 21, and the manual packing plate 28 presses against the manual packing material 27 to stably hold the manual packing material 27 in a predetermined position.

[0057] Preferably, the manual on / off assembly 20 further includes at least one manual anti-rotation element 29. The manual anti-rotation element 29 is disposed on the inner wall of the manual valve body 21 of the medium channel 101, and the manual anti-rotation element 29 is located at the end of the rotation path of the manual butterfly plate 24, so as to stop the rotation of the manual butterfly plate 24 by means of the manual anti-rotation element 29.

[0058] As an example, in this embodiment, when the manual butterfly plate 24 rotates within the medium channel 101 and the plane containing the surface of the manual butterfly plate 24 is perpendicular to the axial direction of the pipe body 10, the manual butterfly plate 24 will be stopped and unable to continue rotating, thereby improving the stability of the manual butterfly plate 24 in this position and reducing the possibility of the manual butterfly plate 24 being shaken by the impact of the medium in the medium channel 101, so as to prevent gaps from appearing between the inner wall of the manual valve body 21 of the medium channel 101 and the manual butterfly plate 24.

[0059] Preferably, the automatic on / off assembly 30 further includes at least one second sealing member 35. The second sealing member 35 is disposed between the inner wall of the automatic valve body 31 of the medium channel 101 and the automatic butterfly plate 34, so as to improve the sealing between the inner wall of the automatic valve body 31 of the medium channel 101 and the automatic butterfly plate 34 when the manual-automatic pressure regulating valve assembly is in the blocked state, thereby preventing the medium from passing through the automatic butterfly plate 34.

[0060] In this embodiment, the second sealing member 35 includes at least one second sealing ring 351 and at least one second pressure ring 352. The second sealing ring 351 is fixed to the inner wall of the automatic valve body 31 of the medium channel 101 by the second pressure ring 352.

[0061] As an example, when the drive member 33 controls the automatic butterfly plate 34 to rotate within the medium channel 101 via the automatic rotary valve stem 32, and the plane containing the surface of the automatic butterfly plate 34 is perpendicular to the axial direction of the pipe body 10, the outer periphery of the automatic butterfly plate 34 presses against the second sealing ring 351 to improve the sealing between the inner wall of the automatic valve body 31 of the medium channel 101 and the automatic butterfly plate 34, preventing the medium in the medium channel 101 from passing over the automatic butterfly plate 34.

[0062] In another modified embodiment, the second sealing member 35 includes at least one second sealing ring 351 and at least one second pressure ring 352. The second sealing ring 351 is fixed to the outer periphery of the automatic butterfly plate 34 by the second pressure ring 352.

[0063] As an example, when the drive member 33 controls the automatic butterfly plate 34 to rotate within the medium channel 101 via the automatic rotary valve stem 32, and the plane containing the surface of the automatic butterfly plate 34 is perpendicular to the axial direction of the pipe body 10, the inner wall of the automatic valve body 31 of the medium channel 101 presses against the second sealing ring 351 to improve the sealing between the inner wall of the automatic valve body 31 of the medium channel 101 and the automatic butterfly plate 34, preventing the medium in the medium channel 101 from passing over the automatic butterfly plate 34.

[0065] Specifically, in this embodiment, several screws are used to sequentially pass through the second pressure ring 352, the second sealing ring 351, and the automatic valve body 31 to fix the second sealing ring 351 to the inner wall of the automatic valve body 31 in the medium channel 101.

[0066] Preferably, the second pressure ring 352 is implemented to include a pressure block.

[0067] The second sealing ring 351 is made of rubber so that it can undergo elastic deformation when compressed to fill the gap between the inner wall of the automatic valve body 31 of the medium channel 101 and the automatic butterfly plate 34, thereby improving the sealing performance between the inner wall of the automatic valve body 31 of the medium channel 101 and the automatic butterfly plate 34.

[0068] Preferably, multiple second sealing rings 351 and multiple second pressure rings 352 are implemented, and the multiple second pressure rings 352 correspond to the multiple second sealing rings 351.

This allows for maintenance by replacing worn parts of the second sealing rings 351 when some wear occurs due to prolonged use. Compared to replacing multiple second sealing rings 351 as a whole, this method reduces the cost of replacing the second sealing rings 351.

[0069] Preferably, the automatic on / off assembly 30 further includes an automatic filler 36. The automatic filler 36 is fitted onto the end of the automatic rotary valve stem 32 near the drive member 33. The automatic filler 36 is located at the end of the valve stem shaft 50 away from the automatic butterfly plate 34, and between the automatic rotary valve stem 32 and the automatic valve body 31. This prevents the medium in the medium channel 101 from flowing out through the gap between the valve stem shaft 50 and the automatic valve body 31, and also prevents external dust from adhering to the valve stem shaft 50 and causing damage. Furthermore, the obstruction provided by the automatic filler 36 prevents the valve stem shaft 50 from slipping off the surface of the automatic rotary valve stem 32, ensuring the stable operation of the valve stem shaft 50.

[0070] Preferably, the automatic filler 36 is made of rubber.

[0071] Preferably, the automatic on / off assembly 30 further includes an automatic packing plate 37.
