Description

Technical Field

[0001] The utility model relates to the technical field of pipeline valves, in particular to a novel pipeline valve. Background Art

[0002] In fluid piping systems, valves are control elements. Their main functions are to isolate equipment and piping systems, regulate flow, prevent backflow, and regulate and discharge pressure. They can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

[0003] The connection between existing pipeline valves and pipelines is mostly through flange connection. When installing some larger pipeline valves, one person is required to support the pipeline valve to align the flange on the pipeline valve with the flange on the pipeline, and then another person is required to install the bolts. In this process, the flanges are easily difficult to align due to unbalanced strength of the supporting personnel, which is time-consuming and labor-intensive, and the overall installation efficiency is low. Based on this, a new pipeline valve is provided. Utility Model Content

[0031] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 5 In an embodiment of the present utility model, a novel pipeline valve includes a pipeline valve 1 consisting of a valve body 101 and a connecting flange 102. The connecting flanges 102 are symmetrically fixed to both ends of the valve body 101. A pre-connection component 2 is provided on the outer side of the connecting flange 102 near the top. The pre-connection component 2 is used to achieve pre-connection between the connecting flange 102 and the pipeline flange.

[0033] The pre-connection component 2 includes a pre-hook 201 and a rotating roller 202;

[0034] The pre-hook 201 is symmetrically fixed to both sides of the outer wall of the connecting flange 102 and close to the top of the connecting flange 102 with the vertical center line of the valve body 101 as the center. The rotating roller 202 is rotatably connected to the inner side of the pre-hook 201. The connecting flange 102 is hung on the outer side of the top of the pipeline flange through the pre-hook 201 and the rotating roller 202, so as to achieve pre-connection between the connecting flange 102 and the pipeline flange. The rotating roller 202 is used to reduce rotational resistance when the valve body 101 is adjusted.

[0035] The bottom of the valve body 101 is fixedly connected to a rectangular base 103. A limit assembly 3 is provided on the outer side of the bottom of the valve body 101 and the inner side of the rectangular base 103. The limit assembly 3 is used to achieve a limit connection between the connecting flange 102 and the pipeline flange.

[0036] The limiting component 3 includes a clamping unit and a linkage unit;

[0037] The clamping unit is used to clamp and limit the bottom of the connecting flange 102 and the bottom of the pipeline flange;

[0038] The linkage unit is used to realize the synchronous expansion or contraction operation of the two sets of clamping units;

[0039] The clamping unit includes a T-shaped rack 301, a limiting slide 302, a transmission gear 303, an L-shaped clamping plate 304, a connecting rod 305, and an arc-shaped fixing plate 306;

[0040] The T-shaped rack 301 is fixed to the outer bottom of the valve body 101 and one end close to the connecting flange 102. The connecting rod 305 is fixed to one end of the arc-shaped fixing plate 306. The limiting slide 302 is fixed to one end of the connecting rod 305. The connecting rod 305 and the limiting slide 302 are grouped in pairs. A group of limiting slides 302 is slidably connected to the outer side of the T-shaped rack 301. The transmission gear 303 is rotatably connected to the middle of a group of limiting slides 302 and meshes with the T-shaped rack 301.

[0041] The L-shaped clamping plate 304 is fixed to the outer end of the transmission gear 303. When the limiting slide 302 approaches the connecting flange 102 along the track of the T-shaped rack 301, the transmission gear 303 is limited by the T-shaped rack 301 and rotates, so as to realize the flipping of the L-shaped clamping plate 304 and clamp the bottom of the pipeline flange, and cooperate with the hooking of the pre-connection component 2 and the top of the pipeline flange to realize the limited connection between the connecting flange 102 and the pipeline flange;

[0042] The linkage unit includes a linkage rack 307, a gear roller 308, a screw 309, and a knob 310;

[0043] Two linkage racks 307 are provided. The two linkage racks 307 are respectively fixed to one end of the two arc-shaped fixing plates 306 in the two clamping units. The ends of the two linkage racks 307 away from the arc-shaped fixing plates 306 extend into the interior of the rectangular base 103, and the two linkage racks 307 are symmetrically distributed along the vertical direction.

[0044] The screw 309 is fixed to one end of the gear roller 308. The gear roller 308 is threadedly connected to the inner side of the rectangular base 103 through the screw 309. The gear roller 308 is located between the two linked racks 307 and meshes with the two linked racks 307.

[0045] The knob 310 is fixed to the other end of the gear roller 308. The gear roller 308 is rotated by the knob 310 to push the two linked racks 307 to move closer or farther away synchronously, thereby providing operating power for the two sets of clamping units.

[0046] Through slots 105 for the linkage rack 307 to pass through are formed at both ends of the outer wall of the rectangular base 103 , and threaded holes 104 for the screw rod 309 to be threadedly connected are formed on the side wall of the rectangular base 103 .

[0047] In this embodiment, when the pipeline valve 1 is connected to the pipeline, the operating steps are as follows:

[0048] The pipe valve 1 is transferred as a whole to the middle of the two pipe sections. At this time, the pipe valve 1 is placed from top to bottom, and the connecting flanges 102 at both ends are tangent to the two pipe flange end faces on the two pipe sections respectively. As the connecting flange 102 moves downward, the pre-hook 201 is finally hooked on the outside of the pipe flange, and its rotating roller 202 fits with the outer surface of the pipe flange. At this time, the pre-connection of the connecting flange 102 and the pipe flange is achieved. This structure allows the installer to no longer need to lift the pipe valve 1, so that the installer can free one hand to operate the limit assembly (it should be noted that the initial state of the limit slide 302 is away from the connecting flange 102. At this time, the L-shaped clamping plate 304 is away from the connecting flange 102 and the vertical part of the L-shaped clamping plate 304 is facing downward, that is, at this time the L-shaped clamping plate 304 will not affect the docking between the connecting flange 102 and the pipe flange);

[0049] After completing the pre-connection between the connecting flange 102 and the pipe flange, the installer can hold the pipe valve 1 with one hand and turn the knob 310 with the other hand. The knob 310 drives the gear roller 308 and the screw 309 to rotate. The gear roller 308 and the screw 309 move along the track of the threaded hole 310. At the same time, the gear roller 308 pushes the two linkage racks 307 away from each other (it should be noted that the linkage rack 307 and the gear roller 308 have a certain width, that is, the gear roller 308 can maintain a stable meshing state with the linkage rack 307 during the movement), and the linkage rack 307 pushes the arc to be fixed. The plate 306, the connecting rod 305, the limiting slider 302, the transmission gear 303, and the L-shaped clamping plate 304 move closer to the connecting flange 102. During this process, the transmission gear 303 is limited by the T-shaped rack 301 and rotates. The L-shaped clamping plate 304 rotates synchronously with the transmission gear 303. Finally, the L-shaped clamping plate 304 is flipped and clamped on the outer side of the bottom of the pipe flange. In this way, the connection between the pre-hanging structure 201 and the top of the pipe flange can realize the mutual limitation of the connecting flange 102 and the pipe flange. This structure can prevent the connection flange 102 from slipping off the pipe flange.

[0050] After that, the pipeline valve 1 can be rotated and adjusted to achieve alignment between the connecting flange 102 and the mounting hole of the pipeline flange. At the same time, the direction of the rotating rod of the pipeline valve 1 can be adjusted so that the rotating rod can be rotated more conveniently to open and close the pipeline valve 1 during later operations. During the rotation of the pipeline valve 1, the rotating roller 202 can reduce the rotation resistance during the rotation process.

[0051] By combining the above parts, the pipeline valve 1 can be installed by a single person, which not only saves manpower but also makes the overall installation more convenient and efficient.

[0052] Please refer to Figures 1 to 5, a single clamping unit is provided with two T-shaped racks 301 and two sets of limit slides 302 and a connecting rod 305, and the two T-shaped racks 301 are symmetrically distributed with the vertical center line of the valve body 101 as the center;

[0053] The positions of the pre-hooking hook 201 and the T-shaped rack 301 are staggered with the positions of the mounting holes on the connecting flange 102 .

[0054] In this embodiment: through this structure, two pre-hooks 201 and two L-shaped frame plates 304 can be correspondingly provided on a single connecting flange 102, thereby achieving full-range wrapping of the pipeline flange, thereby ensuring the stable installation of the pipeline valve 1 and facilitating the subsequent rotation and adjustment operation of the pipeline valve 1.

[0055] Please refer to Figures 1 to 4 The bottom horizontal height of the rectangular base 103 matches the bottom horizontal height of the connecting flange 102 , and the bottom horizontal height of the knob 310 is higher than the bottom horizontal height of the rectangular base 103 .

[0056] In this embodiment, the rectangular base 103 allows the pipeline valve 1 to be stably placed on the ground, thereby facilitating daily storage and placement.

[0057] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
