Technical Field

[0001] The present application relates to the technical field of throttle valves, and in particular to a throttle valve that is easy to install. Background Art

[0002] With the continuous development of industrial technology, throttle valves, as an important fluid control component, are widely used in various industrial occasions. However, traditional throttle valves often have problems such as complex operation and low efficiency during installation and removal. In particular, the removal process usually requires professional tools and complicated steps, which not only increases maintenance costs, but also affects the overall operating efficiency of the equipment. Therefore, we propose a throttle valve that is easy to install to solve this problem.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] The present application provides a throttle valve that is easy to install and adopts the following technical solution:

[0006] A throttle valve that is easy to install includes a throttle valve body, a first connecting pipe is fixedly connected to the outer side of the throttle valve body, a second connecting pipe is installed on the outer side of the first connecting pipe, and a mounting mechanism is arranged on the second connecting pipe; the mounting mechanism includes a limit ring, the limit ring is installed on the outer side of the second connecting pipe, a first limit block is fixedly connected to the outer side of the limit ring, a second limit block is fixedly connected to the outer side of the limit ring, a limit assembly is arranged on the second limit block, and a bolt is installed on the first limit block.

[0007] Preferably, the limiting assembly comprises a turning handle, the turning handle is rotatably connected to the top of the second limiting block, and the bottom of the turning handle is fixedly connected to the first bevel gear.

[0008] Preferably, a second bevel gear is meshed on the outer side of the first bevel gear, the second bevel gear is rotatably connected to the inner side of the second limit block, and a threaded rod is fixedly connected to the side of the second bevel gear away from the first bevel gear, and the threaded rod passes through the first limit block and is threadedly connected to the inner side of the bolt.

When the first bevel gear rotates, the first bevel gear drives the second bevel gear at the bottom to rotate. When the second bevel gear rotates, the second bevel gear drives the threaded rod to rotate. Since the threaded rod passes through the first limit block and is threadedly connected with the bolt installed on the first limit block, the rotation of the turning handle can make the threaded rod and the bolt threadedly connected.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-4 This application is described in further detail.

[0019] The present application embodiment discloses a throttle valve that is easy to install. Figure 1-4 A throttle valve that is easy to install, comprising a throttle valve body 1, a first connecting pipe 2 is fixedly connected to the outer side of the throttle valve body 1, a second connecting pipe 3 is installed on the outer side of the first connecting pipe 2, and a mounting mechanism is provided on the second connecting pipe 3;

[0020] The mounting mechanism includes a limiting ring 4, which is mounted on the outside of the second connecting pipe 3, a first limiting block 5 is fixedly connected to the outside of the limiting ring 4, a second limiting block 6 is fixedly connected to the outside of the limiting ring 4, a limiting assembly is arranged on the second limiting block 6, and a bolt is installed on the first limiting block 5.

[0021] Reference Figure 1-4 The limiting assembly includes a turning handle 7, which is rotatably connected to the top of the second limiting block 6, and a first bevel gear 8 is fixedly connected to the bottom of the turning handle 7.

[0022] Reference Figure 1-4 , the outer side of the first bevel gear 8 is meshed with a second bevel gear 9, and the second bevel gear 9 is rotatably connected to the inner side of the second limit block 6. The side of the second bevel gear 9 away from the first bevel gear 8 is fixedly connected with a threaded rod 11, and the threaded rod 11 passes through the first limit block 5 and is threadedly connected to the inner side of the bolt; by sleeve-arranging the limit ring 4 on the outer side of the pipeline, the staff pushes the first limit block 5 and the second limit block 6 to clamp them toward the center. After the clamping work is completed, the staff holds the outer side of the first limit block 5 and the second limit block 6 with one hand, and rotates the turning handle 7 with the other hand. Since the turning handle 7 is rotatably connected to the inner side of the second limit block 6, the second limit block 6 is fixedly connected to the limiting ring 4, and the bottom of the turning handle 7 is fixedly connected with the first bevel gear Wheel 8, the outer side of the first bevel gear 8 is meshed with a second bevel gear 9, and the second bevel gear 9 is fixedly connected to the threaded rod 11, so the staff can drive the first bevel gear 8 at the bottom to rotate by turning the handle 7. When the first bevel gear 8 rotates, the first bevel gear 8 drives the second bevel gear 9 at the bottom to rotate. When the second bevel gear 9 rotates, the second bevel gear 9 drives the threaded rod 11 to rotate. Since the threaded rod 11 passes through the first limit block 5 and is threadedly connected with the bolt installed on the first limit block 5, the rotation of the handle 7 can make the threaded rod 11 threadedly connected with the bolt. When the rotation continues, the distance between the first limit block 5 and the second limit block 6 can be reduced, thereby locking the pipeline.

[0023] Reference Figure 1-4 A sealing ring 10 is installed on the inner side of the second connecting pipe 3. The sealing ring 10 is made of rubber. The rubber material is durable, which reduces the frequency of later replacement and reduces costs. It can also increase the sealing between the device and the pipeline to prevent leakage of gas or fluid. The first connecting pipe 2 and the second connecting pipe 3 are connected by mechanical sealing.

[0024] The implementation principle of a throttle valve that is easy to install in the embodiment of the present application is as follows: when the staff needs to install the device, first insert the limit ring 4 to set it on the outside of the pipe, and the staff pushes the first limit block 5 and the second limit block 6 to clamp them toward the center. After the clamping work is completed, the staff holds the outside of the first limit block 5 and the second limit block 6 with one hand, and turns the handle 7 with the other hand. Since the handle 7 is rotatably connected to the inside of the second limit block 6, the second limit block 6 is fixedly connected to the limit ring 4, and the bottom of the handle 7 is fixedly connected to the first bevel gear 8, the outside of the first bevel gear 8 is meshed with the second bevel gear 9, and the second bevel gear 9 is fixedly connected to the threaded rod 11, so the staff turns the handle 7 to drive the bottom The first bevel gear 8 at the top rotates, and when the first bevel gear 8 rotates, the first bevel gear 8 drives the second bevel gear 9 at the bottom to rotate, and when the second bevel gear 9 rotates, the second bevel gear 9 drives the threaded rod 11 to rotate. Since the threaded rod 11 passes through the first limit block 5 and is threadedly connected with the bolt installed on the first limit block 5, the rotation of the turning handle 7 can make the threaded rod 11 and the bolt be threadedly connected. When the rotation is continued, the distance between the first limit block 5 and the second limit block 6 can be reduced, thereby locking the pipeline. The staff can install and disassemble the throttle valve by manually rotating the turning handle 7, without the need to use professional tools and complicated steps, thereby reducing the operation difficulty and maintenance cost.
