Description

Technical Field

[0001] This invention belongs to the field of quick-replacement blade valves, and specifically relates to a quick-replacement blade valve and its replacement method. Background Technology

[0002] With the development of modern technology and industry, the number of pipeline systems using valves is gradually increasing, as are pipeline systems with high-density viscous media, such as automotive paint spraying pipelines. The requirements of pipeline systems and the emergence of new processes have opened up application areas for quickly replaceable vane valves. Due to the increase in pipeline systems using viscous media such as paint, the improved mechanical operation capabilities within pipelines, and the rapid increase in the amount of viscous media on the inner walls of pipelines, conventional rotary valves are no longer sufficient to achieve normal operation, leading to the demand for quickly replaceable vane valves.

[0003] In industries, particularly those involving pipelines carrying high-density viscous media such as automotive painting, the treatment and reuse of organic waste gas is becoming increasingly widespread and important. These systems often contain high concentrations of viscous media that adhere to the surfaces of pipes and ventilation devices. Within a short period, this viscous media can accumulate on ventilation devices (valves), causing them to malfunction. Therefore, these high-concentration viscous media systems require a type of damper with rapidly replaceable blades that can maintain normal ventilation conditions and operate reliably over the long term.

[0004] The valves in this ventilation system are easily and quickly covered by viscous media, and the layer will become thicker and thicker, eventually leading to the following problems: (1) the valves cannot be opened or closed normally; (2) the blades are deformed; (3) the valve shaft is twisted and deformed; (4) the actuator is damaged. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a quick-replacement vane valve and its replacement method. The quick-replacement vane valve provided by this invention has a long service life, the vanes and valve shaft are not easily deformed, the actuator operates normally for a long time, and the vanes can be quickly replaced. These vanes are easy to disassemble and clean, and can be reused continuously.

[0006] The above-mentioned objective of this invention is achieved through the following technical solution:

[0007] The bladed damper can be quickly replaced, including: valve body (including flange), bushing, rotating mechanism, and blade assembly mechanism. The blade assembly mechanism includes: blades, blade connecting shafts, blade handles, and a locking mechanism. The locking mechanism includes: a locking shaft, a rotating handle, and a wing bolt. The blade connecting shaft and the blades are fixed together by bolts. The rotating handle is mounted on the locking shaft, allowing the locking shaft and the blade connecting shaft to rotate flexibly. The rotating mechanism includes: a rotating arm, a connecting rod, and a rotating shaft. The rotating arm is connected to the rotating shaft and fixed to the connecting rod. The actuator is mounted on the rotating shaft and is assembled and fixed to one of the rotating shafts. When the actuator operates, it drives the other rotating shafts to rotate through this shaft and the connecting rod. The other end of the rotating shaft protrudes in a straight line and is inserted into the locking mechanism during assembly. The locking mechanism is rotated to a fixed angle by rotating the handle, and then the locking mechanism and the rotating mechanism are fixed together by the wing bolt, thus completely fixing the blades and the rotating shafts. The blade assembly mechanism and the rotating mechanism become one unit, and the blades can then move through the actuator and the rotating mechanism. Similarly, by loosening the wing bolt and rotating the locking shaft in the opposite direction by the same angle, the blades can be directly disassembled.

[0008] The blades are made of stainless steel plates, with blade handles attached to them;

[0009] The rotating handle rotates the locking shaft to a fixed angle of 85-95°.

[0010] The bushing is used between the valve body and the shaft, and has the functions of protecting the shaft from wear and fixing the relative position of the shaft;

[0011] The bushing is made of seamless steel pipe, ensuring flexible shaft rotation and good shaft positioning; the blade connecting shaft, locking shaft, and rotating shaft are all machined from round steel.

[0012] The connecting rod is a structure composed of a straight-line and an L-shaped double connecting rod pin connection, and is installed on the valve;

[0013] The rotating handle is mounted on the locking shaft and can be connected by welding; the height of the rotating handle is 20mm or more.

[0014] The rotating arm in the rotating mechanism is connected to the rotating shaft, and the connection method can be welding; the rotating arm and the connecting rod can be fixed with a pin.

[0015] The blade is connected to the blade handle, and the connection method can be welding.

[0016] The specific steps of the quick-replacement blade damper replacement method provided by this invention are as follows:

[0017] The blades are fixed to the blade connecting shaft with bolts, and the blade connecting shaft and the rotating shaft are connected by a plug-in method. A rotating handle is located on the locking shaft for easy control of its rotation. The blades have a 20-26mm folded edge perpendicular to the side of the locking shaft. When disassembling, installing, and fixing the locking mechanism, the rotating handle rests against the edge of this folded edge, thus accurately controlling the rotation angle of the handle. This allows for quick alignment of the rotating and locking mechanisms during blade disassembly and installation, facilitating rapid blade removal and installation. Rotating the locking shaft until its opening is parallel to the opening of the blade connecting shaft, and tightening the wing bolts, allows for quick installation or removal of the blades, at which point the blades can be cleaned or replaced. Next, rotating the locking shaft until its opening is perpendicular to the opening of the blade connecting shaft, and tightening the wing bolts, fixes the valve blade assembly to the rotating mechanism, allowing the valve to operate normally. The opening is located on the rotating shaft.

[0018] The advantages of this invention compared to the prior art are:

[0019] This invention provides a quick-replacement vane valve with good structural rigidity, convenient disassembly and installation, and long service life. It is beneficial for pipeline systems with high viscous media density and can be widely used in systems with high viscous media concentration in industries such as automotive, chemical, energy, food, and catering. It can be connected to a valve and used with a pneumatic or electric actuator.

[0020] The rotation mechanism and locking mechanism are set accurately and precisely. The locking mechanism can be adjusted to quickly disassemble and install the blade. After the blade is installed, the locking mechanism rotates and locks, and the valve can operate normally. The blade is appropriately bent and protrudes at the locking mechanism to control the position of the locking handle on the locking mechanism when the blade is disassembled and tightened. This accurately controls the positional coordination between the rotation mechanism and the locking mechanism when the valve blade is disassembled and installed, which is more conducive to the quick disassembly and installation of the valve blade.

[0021] A handle is installed on the valve blade to facilitate manual operation for blade removal and installation. Attached Figure Description

[0030] Example 1

[0031] A type of quick-change blade valve, such as Figure 1 As shown, the device includes a valve body 1, a bushing, a rotating mechanism, and a blade assembly mechanism. The blade assembly mechanism includes: blades 2, a blade handle 3, a blade connecting shaft 4, and a locking mechanism. The locking mechanism includes: a locking shaft 5, a rotating handle 9, and a wing bolt 6. The blade connecting shaft 4 is fixed to the blades 2 by the wing bolt 6. The rotating handle 9 is mounted on the locking shaft 5, allowing flexible rotation between the locking shaft 5 and the blade connecting shaft 4. The rotating mechanism includes: a rotating arm 12, a connecting rod, and a rotating shaft 8. The rotating arm 12 is connected to the rotating shaft 8 and fixed to the connecting rod. An actuator 13 is mounted on... On the rotating shaft 8, one end extends out and is assembled with the actuator 13. The actuator 13 drives all the rotating shafts 8 to rotate via a connecting rod. The other end of the rotating shaft 8 protrudes in a straight line and is inserted into the locking mechanism during assembly. By rotating the handle 9, the locking shaft 5 is rotated 90°, and then the locking mechanism and the rotating mechanism are fixed by the wing bolt 6, thus completely fixing the blade 2 to the rotating shaft 8. The blade assembly mechanism and the rotating mechanism become one unit, and the blade 2 can then perform the action process through the actuator 13 and the rotating mechanism. Similarly, by loosening the wing bolt 6 and rotating the locking shaft 5 in the opposite direction by the same angle, the blade 2 can be directly disassembled. The rotating mechanism and the locking mechanism of the valve are located at opposite ends of the valve.

[0032] Example 2

[0033] A quick-change vane valve includes a valve body 1, a vane 2, a vane handle 3, a vane connecting shaft 4, a locking shaft 5, a wing bolt 6, a bearing 7, a rotating shaft 8, a rotating handle 9, an L-shaped connecting rod 10, a straight connecting rod 11, a rotating arm 12, an actuator 13, and an opening 14; the quick-change method is as follows:

[0034] The blade handle 3 is welded to the blade 2. The blade 2 is fixed to the blade connecting shaft 4 with bolts. The blade connecting shaft 4 and the rotating shaft are connected by a plug-in method. The rotating handle 9 is welded to the locking shaft 5 to facilitate the control of the rotation of the locking shaft 5. The blade 2 has a 20mm folded edge vertically on the side of the locking shaft 5. When disassembling, installing, and fixing the locking mechanism, the rotating handle rests on one side of the folded edge, thereby accurately controlling the rotation angle of the rotating handle 9. This allows for quick alignment of the structural position between the rotating mechanism and the locking mechanism at the plug-in position, facilitating the quick disassembly and installation of the blade 2. Specifically: Rotate the locking shaft 5 until the opening 14 is parallel to the opening 14 of the blade connecting shaft 4. After tightening the wing bolt 6, the blade 2 can be quickly installed or removed. At this time, the blade 2 can be cleaned and replaced. See Figure 3 , Figure 4 Next, rotate the locking shaft 5 until the opening 14 is perpendicular to the direction of the opening 14 of the blade connecting shaft 4. After tightening the butterfly bolt 6, the valve blade assembly mechanism and the rotating mechanism can be fixed. At this time, the valve can work normally. See Figure 5 , Figure 6 .
