Technical Field

[0001] The utility model belongs to the technical field of throttle valve disassembly, and particularly relates to a device for disassembling the nozzle of a throttle valve. Background Art

[0002] Throttle valves are often provided in fluid transportation pipelines, which have the function of regulating fluid flow. As Figure 1 shown, the throttle valve 10 includes a valve body 101 and a valve cover 102 detachably connected to the valve body 101. Among them, the valve body 101 and the valve cover 102 jointly define a fluid movement channel 103. In this way, the fluid can move along the channel 103.

[0003] At the same time, the throttle valve 10 further includes an adjustment assembly 104 disposed in the channel 103, and the adjustment assembly 104 is used to adjust the flow rate of the fluid. The adjustment assembly 104 includes a valve seat 1041 and a nozzle 1042 connected together by threads, and a liquid flow hole 1043 communicating with the channel 103 is provided on the nozzle 1042. In this way, the fluid entering the valve body 101 can flow out along the channel 103 after the flow rate is adjusted through the liquid flow hole 1043. In addition, the flow rate of the fluid can be adjusted by replacing the nozzle 1042 with different specifications of the liquid flow hole 1043.

[0004] In the prior art, when replacing the nozzle 1042, it is necessary to separate the valve body 101 from the valve cover 102, extend a disassembly tool into the valve body 101 from the channel 103, and form a relative fixation with the nozzle 1042. At the same time, the staff twists the disassembly tool, so that the nozzle 1042 is disengaged from the valve seat 1041, and the nozzle 1042 is manually taken out of the valve body 101. When installing the nozzle 1042, the staff first places the nozzle 1042 on the valve seat, and then twists the nozzle again with the disassembly tool. Thus, the replacement of the nozzle 1042 is completed.

[0005] In this way, although the nozzle 1042 can be replaced, during the manual operation of the staff, it is easy to drop the nozzle 1042 into the channel 103 due to the negligence of the staff, resulting in the technical problem of blocking the channel 103. Summary of the Utility Model

The throttle valve includes a channel for fluid movement jointly defined by a valve body and a valve housing, and an adjustment assembly for adjusting the fluid flow rate is disposed in the channel.

[0007] Among them, the adjusting component includes a valve seat and a nozzle that are connected to each other by threads.

[0008] The device further includes a screwing mechanism that is configured to enter the valve body along the channel and connect to the nozzle.

[0009] In one embodiment, the screwing mechanism includes a fixing head that is sleeved on the nozzle and forms a relative fixation with the nozzle, and a connecting rod that is disposed on the fixing head and extends outward along the fixing head.

[0010] In one embodiment, a force-applying rod is disposed on the connecting rod for extending the lever arm for applying a force to the connecting rod.

[0011] In one embodiment, the fixing head is made of a magnetic material for adsorbing the nozzle on the screwing mechanism.

[0012] In one embodiment, the screwing mechanism further includes a pin disposed on the fixing head for connecting the fixing head and the connecting rod to each other.

[0013] In one embodiment, the nozzle includes a connecting portion that is threadedly connected to the valve seat and a screwing portion that extends outward along the connecting portion for connecting to the fixing head. A rib that extends radially outward for limiting the axial movement of the nozzle is disposed on the connecting portion. The device further includes a fixing sleeve sleeved on the connecting rod, and the fixing sleeve is configured to cooperate with the rib.

[0014] In one embodiment, the free end of the fixing sleeve is made of a magnetic material for adsorbing the rib on the fixing sleeve.

[0015] In one embodiment, a supporting portion is disposed in the fixing sleeve, and the supporting portion is configured to allow the connecting rod to pass through and support the connecting rod radially inward.

[0016] In one embodiment, a handle is further disposed on the fixing sleeve for providing a fulcrum for the applied force.

[0017] In one embodiment, the fixing sleeve is axially provided with a split structure and is configured to be connected to each other in a selectable manner.

[0018] Generally speaking, compared with the prior art by the above technical solution conceived by the present utility model, the following beneficial effects can be achieved:

[0019] In the present utility model, a screwing mechanism is provided and configured to be able to enter the valve body along the channel and be connected to the nozzle. In this setting, rotating the screwing mechanism can drive the nozzle to rotate together, so that the nozzle can be detached from the valve seat.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a device for disassembling the nozzle of a throttle valve according to the present utility model with reference to the drawings.

[0027] As Figure 1 shown, the throttle valve 10 includes a valve body 101 and a valve cover 102 detachably connected to the valve body 101. Among them, the valve body 101 and the valve cover 102 jointly define a channel 103 for fluid movement. In this way, the fluid can move along the channel 103.

[0028] Meanwhile, the throttle valve 10 further includes an adjusting component 104 disposed in the channel 103, and the adjusting component 104 is used to adjust the flow rate of the fluid. Moreover, an external thread (not shown in the figure) is provided along the adjusting component 104 on the adjusting component 104, and an internal thread (not shown in the figure) is provided along the channel in the channel 103, and the internal thread and the external thread are arranged to cooperate with each other. In this way, the adjusting component 104 can be detachably disposed in the channel 103.

[0029] In addition, the adjusting component 104 includes a valve seat 1041 connected to the channel 103, and a through hole (not shown in the figure) penetrating along the axis of the valve seat 1041 is formed on the valve seat 1041, and the through hole is used to communicate with the channel 103 to jointly form a path for the fluid to move.

[0030] Meanwhile, as Figure 2 shown, the adjusting component 104 further includes a nozzle 1042, and the nozzle 1042 includes a connecting portion 10421 and a screwing portion 10422 extending along the end face of the connecting portion 10421. Among them, the connecting portion 10421 is disposed in the through hole formed by the valve seat 1041 and is arranged to be in threaded cooperation with the valve seat 1041, and the screwing portion 10422 extends out along the valve seat 1041 for cooperating with a disassembly tool. It should be noted that a liquid flow hole 1043 penetrating along its axis for communicating with the channel 103 is provided on the nozzle 1042.

[0031] Preferably, as Figure 2 shown, a radially outwardly extending rib 1044 is further provided at the end of the external thread on the connecting portion 10421, and the rib 1044 is used to abut against the end face of the valve seat 1041 to prevent the nozzle 1042 from being screwed into the valve seat 1041 excessively, resulting in the separation of the nozzle 1042 from the valve seat 1041.

[0032] In this setting mode, the fluid can enter the valve body 101 along the channel 103 and be discharged after the flow rate is adjusted through the liquid flow hole 1043 in the valve body 101. Thus, the throttling work is completed.

[0033] However, when it is necessary to adjust the flow rate of the fluid, the valve body 101 and the valve cover 102 are separated from each other, and a disassembly tool for disassembling the nozzle 1042 is lowered along the channel 103, and the disassembly tool is made to cooperate with the screwing portion 10422 to disassemble the nozzle 1042, and a nozzle 1042 with a liquid flow hole 1043 of a different size is installed after disassembly, so as to adjust the radial distance of the path formed by the liquid flow hole 1043. Thus, the flow rate of the fluid is adjusted. It should be noted that these structures of the throttle valve 10 are well known to those skilled in the art.

[0034] Figure 3 Schematically shows the overall structure of the device 100 for disassembling the nozzle of the throttle valve according to the present utility model. In the embodiment as shown in Figure 3 In the embodiment shown, the device 100 for disassembling the nozzle of the throttle valve includes a screwing mechanism 1, and the screwing mechanism 1 is used to enter into the valve body 101 along the channel 103 and is connected to the screwing part 10422. In this setting, when a force is applied to the screwing mechanism 1, the screwing mechanism 1 can drive the screwing part 10422 to move, so as to disassemble the nozzle 1042.

[0035] In one embodiment, as shown in Figure 3 In the figure, the screwing mechanism 1 includes a fixed head 11, and the fixed head 11 is arranged to be sleeved on the screwing part 10422 and form a relatively fixed connection with the screwing part 10422. In this embodiment, the inner contour of the fixed head 11 and the screwing part 10422 are arranged as a polygon structure with complementary shapes. In this way, the fixed head 11 and the screwing part 10422 can be stably connected together.

[0036] At the same time, the screwing mechanism 1 further includes a connecting rod 12, and the connecting rod 12 is arranged on the fixed head 11 and extends outward. In this way, the axial length of the fixed head 11 can be extended, so that when in use, the connecting rod 12 can be located outside the channel 103. Thus, it is convenient to apply the force.

[0037] In one embodiment, the screwing mechanism 1 further includes a force-applying rod 13, and the force-applying rod 13 is used to provide a fulcrum for applying the force. In this embodiment, the force-applying rod 13 is arranged at the free end of the connecting rod 12 and is perpendicular to the connecting rod 12. In this way, when it is necessary to apply a force to the connecting rod 12, the force can be transmitted from the force-applying rod 13 to the connecting rod 12 by rotating the force-applying rod 13.

[0038] Thus, the lever arm of the force can be extended, so that the connecting rod 12 can be rotated in a labor-saving manner. Preferably, the handles 23 are arranged in two corresponding ways, so as to further facilitate the application of the force. And in this way, the radial length of the device 100 can also be increased, so as to prevent the device 100 from falling into the channel 103 and causing blockage to the channel 103.

[0039] In this setting, when it is necessary to disassemble the nozzle 1042, the valve body 101 and the valve cover 102 are separated from each other, and the screwing mechanism 1 is made to enter into the valve body 101 along the channel 103. At the same time, the fixed head 11 is sleeved on the screwing part 10422, and the fixed head 11 and the screwing part 10422 are relatively fixed.

[0040] Then, an acting force is applied to the force-applying rod 13. During this process, the acting force will be transmitted along the force-applying rod 13 to the connecting rod 12, and drive the fixed head 11 to rotate. At this time, the fixed head 11 will drive the screwing part 10422 to rotate synchronously until the nozzle 1042 is disengaged from the valve seat 1041. Thus, the nozzle 1042 is disassembled.

[0041] However, when the nozzle 1042 needs to be installed, the nozzle 1042 is placed into the fixed head 11, and then the screwing mechanism 1 with the nozzle 1042 is inserted into the valve body 101 along the channel 103, and the nozzle 1042 is positioned on the valve seat 1041. Meanwhile, the force-applying rod 13 is screwed in the direction opposite to the above-mentioned direction, thereby completing the installation of the nozzle 1042.

[0042] According to a preferred embodiment of the present invention, the fixed head 11 is made of a magnetic material. In this way, the fixed head 11 can generate an adsorbing acting force on the nozzle 1042. In this setting, after the nozzle 1042 is screwed out of the valve seat 1041 by the screwing mechanism 1, an axially outward acting force can be applied to the screwing mechanism 1, so that the nozzle 1042 can be stably transported from the valve body 101 to the outside world, avoiding the nozzle 1042 falling off the fixed head 11 during the outward movement and blocking the channel 103. It should be noted that in the prior art, the nozzle 1042 is usually made of a metal material.

[0043] According to a preferred embodiment of the present invention, the screwing mechanism 1 further includes a pin 14 arranged on the fixed head 11, and the pin 14 is used to connect the fixed head 11 and the connecting rod 12 in a relatively fixed manner. In this way, when the pin 14 is removed, the fixed head 11 and the connecting rod 12 can be separated from each other. Thus, the corresponding fixed head 11 can be replaced according to the different specifications of the screwing part 10422, thereby increasing the applicability of the screwing mechanism 1.

[0044] In one embodiment, the device 100 further includes a fixing mechanism 2 sleeved on the connecting rod 12. In this embodiment, the fixing mechanism 2 includes a fixing sleeve 21, the fixing sleeve 21 is arranged in a hollow cylindrical shape, and the inner contour of the free end of the fixing sleeve 21 is configured to cooperate with the rib 1044 on the nozzle 1042.

[0045] In this setting, during use, the fixed head 11 and the connecting rod 12 are inserted into the fixing sleeve 21. Meanwhile, the fixed head 11 is sleeved on the screwing part 10422, and the fixed head 11 and the screwing part 10422 are relatively fixed.

[0046] In addition, an acting force is applied to the force-applying rod 13, and the acting force will be transmitted along the force-applying rod 13 to the connecting rod 12, driving the fixed head 11 to rotate, thereby driving the nozzle 1042 to rotate until the nozzle 1042 is disengaged from the valve seat 1041.

[0047] Then, the fixing sleeve 21 is sleeved on the rib 1044, and relative fixation is formed between the fixing sleeve 21 and the rib 1044. Finally, an axially outward acting force is applied to both the fixing sleeve 21 and the force-applying rod 13, so that the nozzle 1042 moves from inside the valve body 101 to the outside. In this way, the fixing sleeve 21 can apply an acting force to the nozzle 1042, further preventing the nozzle 1042 from falling off the fixed head 11 and blocking the channel 103.

[0048] According to a preferred embodiment of the present invention, the free end of the fixing sleeve 21 is made of a magnetic material. In this way, the fixing sleeve 21 can generate an adsorbing acting force on the nozzle 1042, further fixing the nozzle 1042 and the fixing sleeve 21 relative to each other and strengthening the connection between the fixing sleeve 21 and the nozzle 1042.

[0049] In one embodiment, the fixing mechanism 2 further includes a supporting portion 22 disposed inside the fixing sleeve 21, and the supporting portion 22 is disposed along the inner wall of the fixing sleeve 21. At the same time, a threaded hole (not shown in the figure) that penetrates axially is provided on the supporting portion 22, and the threaded hole is for the connecting rod 12 to pass through and form a threaded fit with the connecting rod 12.

[0050] Specifically, an external thread (not shown in the figure) that mates with the threaded hole is provided on the connecting rod 12 along the connecting rod 12. In this way, the supporting portion 22 can support the connecting rod 12 radially inward, preventing the connecting rod 12 from deforming during the force application process.

[0051] According to a preferred embodiment of the present invention, the fixing mechanism 2 further includes a handle 23 disposed on the fixing sleeve 21, and the handle 23 is used to provide a fulcrum for the acting force. Thus, when the fixing sleeve 21 and the nozzle 1042 are fixed relative to each other, an acting force can be applied to the handle 23, and the acting force is transmitted to the nozzle 1042 along the connecting sleeve 21. In this way, it is convenient to move the nozzle 1042 from the valve body 101 to the outside.

[0052] In the present utility model, the handles 23 are provided in two corresponding ways and are respectively perpendicular to the axis of the fixed sleeve 21. In this way, it is further convenient to apply the acting force, and the radial length of the device 100 can also be increased, thereby preventing the device 100 from falling into the channel 103 and causing blockage to the channel 103.

[0053] According to a preferred embodiment of the present utility model, the fixed sleeve 21 is provided as a split structure in the axial direction and is configured to be selectively connected into one body in a threaded connection manner. In this way, according to the different specifications of the ribs 1044 on the nozzle 1042, the corresponding connection sleeve 21 can be selected, so that the connection sleeve 21 can be connected to the nozzle 1042 in a relatively fixed manner. Thus, the applicability of the device 100 can be improved.

[0054] The operation of the device 100 for disassembling the nozzle of the throttle valve according to the present utility model is as follows.

[0055] First, select the corresponding fixed head 11 and connection sleeve 21 according to the specification of the nozzle 1042, so that the device 100 can be connected to the nozzle 1042 in a relatively fixed manner.

[0056] Secondly, separate the valve body 101 from the valve cover 102, and insert the device 100 into the valve body 101 along the channel 103. At the same time, sleeved the fixed head 11 on the screwing part 10422, so as to form a fixed connection between the device 100 and the nozzle 1042.

[0057] Thirdly, apply an acting force to the force-applying rod 13, and the acting force will be transmitted along the force-applying rod 13 to the connecting rod 12 and drive the fixed head 11 to rotate. At this time, the fixed head 11 will drive the screwing part 10422 to rotate synchronously until the nozzle 1042 is separated from the valve seat 1041.

[0058] Then, sleeved the connection sleeve 21 on the rib 1044 and make the connection sleeve 21 relatively fixed to the nozzle 1042. At the same time, apply an acting force to the handle 23, and at this time the acting force will be transmitted along the connection sleeve 21 to the nozzle 1042. In this way, the nozzle 1042 can be moved out of the valve body 101. Thus, the disassembly work of the nozzle 1042 is completed. And, by forming a relative fixation between the fixed head 11 and the connection sleeve 21 and the nozzle 1042 together, it can prevent the nozzle 1042 from falling off during the outward movement and causing blockage to the channel 103.

[0059] However, when the nozzle 1042 needs to be installed, the nozzle 1042 is first placed into the fixed head 11, and then the device 100 with the nozzle 1042 is inserted into the valve body 101 along the channel 103, and the nozzle 1042 is positioned on the valve seat 1041. At the same time, the force application rod 13 is screwed in the direction opposite to the above direction, thereby completing the installation of the nozzle 1042.

[0060] It can be understood that the present utility model is described by way of some embodiments. Those skilled in the art will appreciate that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
