Description

Technical Field

[0001] This utility model relates to the field of round tube adapter technology, and in particular to a round tube adapter extension rod. Background Technology

[0002] With the continuous development of industrial technology, the performance and quality requirements for round tube adapter extension rods are becoming increasingly stringent. On the one hand, the adapter extension rods are required to have good connection strength and stability to ensure that they do not loosen or break during use. On the other hand, they are also required to have good corrosion resistance, wear resistance, and sealing performance to adapt to different working environments and media transportation requirements. At the same time, in order to improve installation efficiency and convenience, some new round tube adapter extension rods also adopt quick connection structures or adjustable designs, making the connection and extension of round tubes faster and more convenient.

[0003] Currently, the location of valves installed in pipeline systems is fixed during the civil engineering phase. Since valve actuators are directly connected to the valve drive shaft, their installation location is also fixed. If these locations have unfavorable operating conditions, such as high humidity, acid or alkali content, corrosive substances, or the actuator being directly immersed in the bottom liquid medium, there is a risk of actuator failure after a certain period of use. Furthermore, if there is a large amount of liquid medium at the actuator's installation height, it takes time to remove some of the liquid medium from the bottom before the actuator can be exposed, affecting the rapid response capability of the entire pipeline system and significantly reducing the ability to react in emergencies such as pipe bursts. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a circular tube adapter extension rod, which aims to improve the existing technology where, if there is a large amount of liquid medium at the height of the actuator installation, it takes a certain amount of time to first extract some of the liquid medium at the bottom when it is necessary to open and close the valve until the actuator is exposed above the liquid surface before operation can be carried out. This affects the rapid response capability of the entire pipeline device and greatly weakens the response capability in emergency situations such as pipeline bursts.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a circular tube adapter extension rod, comprising a stainless steel tube, a carbon steel tube fixedly connected to the outer wall of the stainless steel tube, a second flange fixedly connected to the bottom of the carbon steel tube, a third reinforcing rib fixedly connected to the top left side of the second flange, a fourth reinforcing rib fixedly connected to the top right side of the second flange, a third reinforcing rib fixedly connected to the top front side of the second flange, a fourth reinforcing rib fixedly connected to the top rear side of the second flange, a first flange fixedly connected to the top of the carbon steel tube, an input shaft rotatably connected to the inner side of the first flange, a first reinforcing rib fixedly connected to the bottom left side of the first flange, a second reinforcing rib fixedly connected to the bottom right side of the first flange, a first reinforcing rib fixedly connected to the bottom front side of the first flange, a second reinforcing rib fixedly connected to the bottom rear side of the first flange, and an output shaft sleeve rotatably connected to the inner bottom of the second flange.

[0006] As a further description of the above technical solution:

[0007] An O-ring is provided on the top of the flange.

[0008] As a further description of the above technical solution:

[0009] A thrust washer is provided at the top center of the flange.

[0010] As a further description of the above technical solution:

[0011] An O-ring is fixedly connected to the bottom end of the second flange.

[0012] As a further description of the above technical solution:

[0013] Limiting blocks are provided on both the left and right sides of the bottom of flange two.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the sleeve is placed horizontally on the ground, and then the output shaft sleeve side of the drive shaft slowly enters the sleeve in the horizontal direction until the shoulder of the input shaft is coplanar with the groove. Then, the thrust washer is connected to the flange one with bolts, and the limit block is locked on the output shaft sleeve with screws. Finally, O-ring one and O-ring two are placed into the corresponding sealing ring grooves. This realizes that the self-weight of the drive shaft is borne by the valve flange one through the outer sleeve, so that the structure is stable. At the same time, the flanges at both ends are equipped with a sealing structure to effectively prevent external liquid from entering the extension rod, avoiding internal corrosion and damage. In addition, the limit block is installed at the bottom to ensure that the drive shaft will not come out of the flange sleeve during transportation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figure 1 - Appendix Figure 3An embodiment of this utility model provides: a round tube adapter extension rod, including a stainless steel tube 7, a carbon steel tube 8 fixedly connected to the outer wall of the stainless steel tube 7, a flange 2 12 fixedly connected to the bottom of the carbon steel tube 8, a third reinforcing rib 17 fixedly connected to the top left side of the flange 2 12, a fourth reinforcing rib 18 fixedly connected to the top right side of the flange 2 12, a third reinforcing rib 9 fixedly connected to the top front side of the flange 2 12, a fourth reinforcing rib 10 fixedly connected to the top rear side of the flange 2 12, a flange 1 3 fixedly connected to the top of the carbon steel tube 8, an input shaft rod 1 rotatably connected to the inner side of the flange 1 3, a first reinforcing rib 15 fixedly connected to the bottom left side of the flange 1 3, a second reinforcing rib 16 fixedly connected to the bottom right side of the flange 1 3, a first reinforcing rib 5 fixedly connected to the bottom front side of the flange 1 3, a second reinforcing rib 6 fixedly connected to the bottom inner side of the flange 2 12, and an output shaft sleeve 11 rotatably connected to the inner bottom of the flange 2 12.

[0026] Specifically, a third reinforcing rib 17 is fixedly connected to the top left side of flange 2 12. The third reinforcing rib 17 has a regular shape and can effectively distribute the force from the left side. A fourth reinforcing rib 18 is also fixedly connected to it. The fourth reinforcing rib 18 and the third reinforcing rib 17 work together to enhance the load-bearing capacity of the right side of flange 2 12. A third reinforcing rib 9 is fixedly connected to the top front side, providing additional support for the front side of flange 2 12. A fourth reinforcing rib 10 is fixedly connected to the top rear side. The fourth reinforcing rib 10 works together with the front reinforcing ribs to ensure that flange 2 12 is strong in all directions. It can maintain stability, allowing the input shaft 1 to rotate flexibly within the flange 3, further enhancing the structural stability of the flange 3. A first reinforcing rib 15 is fixedly connected to the bottom left side, which can withstand the tensile and compressive forces from the left side. A second reinforcing rib 16 is fixedly connected to the bottom right side, which works in conjunction with the first reinforcing rib 15 to improve the strength of the right side of the flange 3. A reinforcing rib 5 is fixedly connected to the bottom front side, which provides a stable support for the front side of the flange 3, ensuring that the entire connection structure will not loosen due to vibration or external forces during operation.

[0027] Please see the appendix Figure 4 - Appendix Figure 6 An O-ring 14 is fixedly connected to the bottom of flange 2 12, a thrust washer 2 is provided in the middle of the top of flange 1 3, an O-ring 4 is provided at the top of flange 1 3, and limit blocks 13 are provided on the left and right sides of the bottom of flange 2 12.

[0028] Specifically, O-ring 14 has good elasticity and sealing properties, which can prevent medium leakage in flange 12 and ensure the sealing of the connection. The top of O-ring 14 is tightly fitted and fixedly connected to thrust gasket 2. Thrust gasket 2 has a smooth surface and moderate hardness, which plays a role in positioning and buffering. Flange 13, as another important connecting flange, has O-ring 14 carefully set on its top. The cooperation between O-ring 14 and flange 13 can play a sealing role when flange 13 is connected to other components. Limiting blocks 13 are symmetrically set on the left and right sides of the bottom of flange 12. The limiting blocks 13 have a regular shape and can play a role in positioning and limiting displacement.

[0029] Working principle: The input shaft 1, stainless steel pipe 7, and output shaft sleeve 11 are welded together to form a transmission shaft. At this point, flange 1 3, carbon steel pipe 8, flange 2 12, reinforcing rib 1 5, reinforcing rib 2 6, reinforcing rib 3 9, reinforcing rib 4 10, first reinforcing rib 15, second reinforcing rib 16, third reinforcing rib 17, and fourth reinforcing rib 18 are welded together to form a sleeve. During installation, the sleeve is placed horizontally on the ground. Then, the output shaft sleeve 11 is slowly inserted into the sleeve horizontally until the shoulder of the input shaft 1 is coplanar with the groove. The limiting block 13 is then screwed onto the output shaft sleeve 11, and the sleeve is erected to cooperate with the transmission shaft. The drive shaft can be supported on flange 3 by thrust washer 2, and then O-ring 4 and O-ring 2 14 can be placed into the corresponding sealing groove. This allows the weight of the drive shaft to be borne by valve flange 3 through the outer sleeve, thus stabilizing the structure. The thrust bearing can also reduce the friction generated during transmission. In addition, both upper and lower flanges 3 and flange 2 12 have sealing grooves, and the flanges at both ends have sealing structures to effectively prevent external liquids from entering the extension rod, avoiding internal corrosion and damage. At the same time, a limit block 13 is installed at the bottom to ensure that the drive shaft will not come out of the flange sleeve during transportation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
