It reduces the frequency of replacement, effectively reduces maintenance costs and reduces the waste of speed control valves. It also greatly reduces the impact of thread damage on the sealing of the speed control valve during installation, significantly improving the performance of the actuator.

[0031] 3. In this solution, through the cooperation of the guide seat and the two guide slopes of each slope group, the plug connector can be inserted into the through hole at any angle and then rotated to fix the plug connector and the guide seat, without having to find the corresponding positions of the fixing hole of the guide seat and the fixing block during insertion, thus avoiding the time and tedious operation of repeated alignment, further improving the speed and convenience of connecting the plug connector and the mounting head, saving time, labor and efficiency.

[0032] 4. In this solution, when the plug connector is installed on the mounting head, the trigger component at this time will cause the annular airbag to expand and fill the annular sealing groove, thereby sealing the interface between the mounting head and the plug connector, which can effectively prevent the fluid from leaking from the interface between the mounting head and the plug connector, significantly improve the sealing effect of the mounting head and the plug connector, and thereby improve the performance of the valve body and subsequent use effect.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-12A speed regulating valve that is easy to disassemble and assemble is installed on an actuator 1, comprising: a mounting head 2, which is arranged on the actuator 1, and a through hole 3 is opened in the mounting head 2; a valve body 4, which is detachably connected to the mounting head 2, and a plug connector 5 adapted to the through hole 3 is arranged on the valve body 4; a fixing mechanism 6, which is arranged in the through hole 3 and is used to fix the plug connector 5 inserted into the through hole 3; a disassembling mechanism 7, which is arranged on the mounting head 2 and is used to release the fixing mechanism 6 from fixing the plug connector 5.

[0049] When in use, the mounting head 2 has been installed at the inlet and outlet of the actuator 1, and can be connected by thread or welding, etc., and the mounting head 2 does not need to be removed later unless necessary. When the valve body 4 is connected to the mounting head 2, the plug connector 5 of the valve body 4 is inserted into the through hole 3 of the mounting head 2. When the plug connector 5 is inserted to the limit position, the plug connector 5 can be fixed by the fixing mechanism 6, and the plug connector 5 can be fixed in the through hole 3, and the end of the plug connector 5 fits the inner wall of the through hole 3. At this time, the connection between the valve body 4 and the mounting head 2 is realized, that is, the installation of the valve body 4 on the actuator 1 is completed, avoiding the current method of installing the valve body 4 by thread, and there is no need to wrap the sealing tape and other operations, and the operation process is simple and convenient. After that, the valve body 4 is connected to the pipe, and the fluid can flow back and forth in the actuator 1 through the valve body 4, the plug connector 5 and the mounting head 2. When the valve body 4 needs to be disassembled later, the fixing mechanism 6 for the plug connector 5 can be released by operating the disassembly mechanism 7, and then the plug connector 5 can be removed from the through hole 3 of the mounting head 2, thus completing the separation of the valve body 4 and the mounting head 2. In summary, the installation and disassembly process of the valve body 4 can be conveniently and quickly completed by connecting and disconnecting the plug connector 5 and the mounting head 2. The disassembly and assembly are simple and easy to use, and operational errors are not likely to occur. Especially in occasions with complex pipelines and narrow spaces, the operation is simpler and faster, saving a lot of time and labor. The installation efficiency of the valve body 4, i.e., the speed regulating valve, is high, the time for equipment commissioning and maintenance is short, the cost is reduced, the use effect is good, and it can be promoted for use.

[0050] At the same time, it avoids the current method of repeatedly disassembling and assembling through threads and the situation that the threads are easily damaged and cannot be disassembled due to thread slippage. The service life is improved, which will reduce the frequency of replacement, effectively reduce maintenance costs, and reduce waste of speed control valves; it also greatly reduces the impact of thread damage on the sealing of the speed control valve during installation, so that the performance of the actuator 1 is significantly improved and the use effect is good.

When the plug connector 5 is inserted into the through hole 3, the guide seat 8 on the plug connector 5 is in a state of sliding fit with the inner wall of the through hole 3, thereby improving the stability of the plug connector 5 when moving; at the same time, when the plug connector 5 is rotated, the guide seat 8 will rotate along the inner wall of the through hole 3, improving its smoothness of rotation. When the plug connector 5 moves and rotates, it will drive the guide seat 8 and the fixing hole 9 to move and rotate, and when the fixing hole 9 is in the position of the fixing mechanism 6, the plug connector 5 will be fixed by the fixing mechanism 6.

[0052] In this embodiment, preferably, please refer to Figure 6-7 9-11, the fixing mechanism 6 includes: an inner groove 61, which is provided on the inner wall of the through hole 3, and a fixing block 62 adapted to the fixing hole 9 is slidably provided on the inner wall of the inner groove 61, and one side of the fixing block 62 is an inclined surface; a first elastic member 63, one end of which is connected to the fixing block 62, and the other end is connected to the inner wall of the inner groove 61, and the first elastic member 63 in the present application adopts a spring or spring damper matching mode. When the plug connector 5 is inserted into the through hole 3, the guide seat 8 moves to the position of the fixing block 62 and squeezes the fixing block 62, so that the fixing block 62 moves into the inner groove 61 and compresses the first elastic member 63, and the plug connector 5 and the guide seat 8 continue to move, and after moving to the specified position, the fixing block 62 is located at the position of the fixing hole 9 at this time, and the fixing block 62 is no longer compressed at this time, and the rebound force of the first elastic member 63 drives the fixing block 62 to enter the fixing hole 9, at this time, the guide seat 8 is restricted and fixed, that is, the plug connector 5 and the valve body 4 are restricted and fixed, that is, the installation of the valve body 4 is completed. During subsequent disassembly, the fixing block 62 is moved toward the inner groove 61 through the disassembly mechanism 7. When the fixing block 62 is separated from the fixing hole 9, the guide seat 8 and the plug connector 5 can be removed from the through hole 3, and the valve body 4 can be easily disassembled.

[0053] In this embodiment, preferably, please refer to Figure 3 , Figure 6 and Figure 8-11The disassembly mechanism 7 includes: a ring plate 71, which is slidably mounted on the outer wall of the mounting head 2, and a traction rope 72 is connected to the ring plate 71; a through hole 73, which is opened on the outer wall of the mounting head 2 and communicates with the inner groove 61, and the other end of the traction rope 72 passes through the through hole 73 and is connected to the fixed block 62. When the valve body 4 needs to be removed from the mounting head 2, the ring plate 71 is pushed to slide along the outer wall of the mounting head 2, and the ring plate 71 will pull the traction rope 72, and the other end of the traction rope 72 will pull the fixed block 62 to move, and the fixed block 62 will move toward the inside of the inner groove 61, so that the fixed block 62 can be separated from the fixing hole 9 and release the restriction on the guide seat 8. When the ring plate 71 is released, the first elastic member 63 will drive the fixed block 62 to return to the initial state, and the fixed block 62 will also pull the traction rope 72 and the ring plate 71 back to the initial position.

[0054] A plurality of grips 20 are arranged on the ring plate 71, and anti-skid patterns are arranged on the grips 20. The ring plate 71 can be moved by holding and pushing the grips 20, which makes operation more convenient. The anti-skid patterns on the grips 20 can improve the anti-skid effect.

[0055] In this embodiment, preferably, please refer to Figure 6 , Figure 8 and Figure 10-11 The outer wall of the mounting head 2 is provided with a wheel frame 21, and a guide wheel 22 is rotatably provided on the wheel frame 21. When the ring plate 71 pulls the traction rope 72 to move or the fixed block 62 returns to pull the traction rope 72, the traction rope 72 will pass through the guide wheel 22, which can not only make the force of the traction rope 72 more concentrated, so that the fixed block 62 or the ring plate 71 moves more smoothly, but also can greatly reduce the friction of the traction rope 72, and at the same time can reduce its wear and tear, thereby increasing the service life of the traction rope 72.

[0056] In this embodiment, preferably, please refer to Figure 3 and Figure 6 The outer wall of the mounting head 2 is provided with a slide groove 10, in which a slider 11 is slidably arranged, and the outer end of the slider 11 is connected to the ring plate 71. When the ring plate 71 slides along the outer wall of the mounting head 2, the ring plate 71 drives the slider 11 to move along the slide groove 10, and the slider 11 can improve the smoothness and stability of the movement of the ring plate 71, and can also limit the ring plate 71.

[0057] In this embodiment, preferably, please refer to Figure 4-7 and Figure 9-11A hidden groove 12 is provided inside the plug connector 5, and the guide seat 8 is slidably connected to the inner wall of the hidden groove 12. A second elastic member 13 is provided between the inner end of the guide seat 8 and the bottom wall of the hidden groove 12. In the present application, the second elastic member 13 is a spring or a combination of a spring and a damper; a plurality of slope groups are provided on the inner wall of the through hole 3, each slope group includes two symmetrical guide slopes 14, and the sides of the two guide slopes 14 facing away from each other are arc surfaces, and a limited sliding area 15 is formed between the two guide slopes 14, and the fixed block 62 is located in the limited sliding area 15.

[0058] When the plug connector 5 is inserted into the through hole 3, when the fixed hole 9 of the guide seat 8 and the fixed block 62 are in a staggered position, the plug connector 5 and the guide seat 8 can be rotated at this time. After the guide seat 8 passes the guide slope 14 position of the through hole 3, the guide seat 8 will be compressed, and the guide seat 8 will move toward the hidden groove 12 and compress the second elastic member 13. After the guide seat 8 passes the guide slope 14, it will be located between the two guide slopes 14 of each slope group, that is, the guide seat 8 is located in the limited sliding area 15 at this time. Then continue to move the plug connector 5, and the guide seat 8 will also move along the limited sliding area 15 at this time. The guide seat 8 squeezes the fixed block 62 to enter the inner groove 61. After moving to the specified position, the fixed block 62 will enter the fixed hole 9 to limit and fix the guide seat 8. At the same time, the plug connector 5 and the guide seat 8 can be moved to the extreme position of the through hole 3 and then rotated. After the guide seat 8 enters the limited sliding area 15, the fixed block 62 will also enter the fixed hole 9. Thus, through the cooperation of the guide seat 8 and the two guide slopes 14 of each slope group, the plug connector 5 can be inserted into the through hole 3 at an arbitrary angle and then rotated to achieve the fixation of the plug connector 5 and the guide seat 8, without having to find the corresponding positions of the fixing hole 9 of the guide seat 8 and the fixing block 62 during insertion, thus avoiding the time and tedious operation of repeated alignment, further improving the speed and convenience of connecting the plug connector 5 and the mounting head 2, saving time and labor, high efficiency and strong practicality.

[0059] In this embodiment, preferably, please refer to Figure 4-7 , Figure 9-10 and Fig.12 The end of the plug connector 5 is provided with an air cavity 16, an annular air bag 17 is provided at the opening of the air cavity 16, an annular sealing groove 18 matching the annular air bag 17 is provided on the inner side wall of the through hole 3, and a trigger component 19 is provided at the end of the plug connector 5. When the plug connector 5 is inserted into the designated position in the through hole 3, that is, when the plug connector 5 is installed on the mounting head 2, the trigger component 19 will be triggered to expand the annular air bag 17, and the position of the annular air bag 17 corresponds to the position of the annular sealing groove 18 in the through hole 3. After the annular air bag 17 expands, it will enter and fill the annular sealing groove 18, so that the interface position of the mounting head 2 and the plug connector 5 can be sealed by the annular air bag 17, which can effectively prevent the fluid from leaking from the interface of the mounting head 2 and the plug connector 5, significantly improve the sealing effect of the mounting head 2 and the plug connector 5, and thus improve the performance of the valve body 4 and the subsequent use effect.

[0060] In this embodiment, preferably, please refer to Figure 4-5 , Fig.10 and Fig.12 The trigger component 19 includes: a linkage chamber 191, which is opened in the plug connector 5 and communicates with the air chamber 16.

The third elastic member 193 in the present application adopts a spring or a combination of a spring and a damper. When the plug connector 5 is inserted into the specified position in the through hole 3, the trigger rod 194 will be squeezed by the inner wall of the installation head 2, and the trigger rod 194 will move toward the linkage chamber 191. The trigger rod 194 will drive the piston plate 192 to move and squeeze the third elastic member 193. The piston plate 192 squeezes the space in the linkage chamber 191, so that the gas in the linkage chamber 191 enters the air chamber 16, and the gas in the air chamber 16 enters the annular airbag 17 to expand it. When the plug connector 5 is removed, the trigger rod 194 is no longer squeezed, and the rebound force of the third elastic member 193 drives the piston plate 192 and the trigger rod 194 to move to the initial state, and the annular airbag 17 also shrinks back to the initial state.
