Description

Technical Field

[0001] This utility model relates to the field of pipeline system technology, specifically to a low-flow-resistance energy-saving gate valve for pipeline systems. Background Technology

[0002] Pipeline systems are networks of pipes used to transport and distribute media (such as water and gas). They mainly consist of pipes, valves, and auxiliary facilities, and are divided into types such as water supply pipeline systems and pipeline monitoring systems.

[0003] Gate valves are used in pipeline systems to control the flow of media within the pipes. Most existing gate valves are screw-driven, controlling the gate to rise and fall within the valve body to open and close the valve and control the flow rate of media in the pipeline. However, as the media continuously flows through the gate valve, and given that the gate valve itself is mostly made of metal, especially during long-term water transportation, the anti-rust coating on the inner wall of the connecting pipes at both ends of the gate valve is easily eroded by the water, causing it to peel off and form rust. This rust occupies the space inside the pipes at both ends of the gate valve, thus obstructing the flow of water through the gate valve, reducing the water flow velocity, and affecting the water supply.

[0004] Therefore, a low-flow-resistance, energy-saving gate valve for pipeline systems is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a low-flow-resistance, energy-saving gate valve for pipeline systems, which can solve the problem of water flow obstruction due to corrosion on the inner walls at both ends of the gate valve.

[0007] The screw has an annular support seat at its lower part, which is located at the bottom of the valve body. The end of the support seat abuts against the port of the connecting pipe. An annular groove is formed on the inner wall of the support seat, and a slot is formed on the top of the support seat. The slot is connected to the annular groove. A gate is provided in the annular groove, and the top of the gate passes through the slot and is rotatably connected to the bottom of the screw.

[0008] Both ends of the support base are provided with rotating shafts. One end of the rotating shaft is rotatably mounted on the connecting base. The side of the connecting base is fixed to the inner wall of the support base through a connecting frame. The other end of the rotating shaft is provided with a number of spaced spiral blades. The spiral blades are inclined and the outer wall of the spiral blades is in clearance fit with the inner wall of the connecting tube. A connecting rod is installed on the inner side of the spiral blades and the connecting rod is fixed on the rotating shaft.

The two ends of the support base correspond to the relatively close ends of the first housing and the second housing, and the ends of the support base are respectively disposed inside the relatively close ends of the first housing and the second housing.

[0010] The valve body also includes a third housing with a bottom opening, which is placed on top of the first housing. The third housing is fixed to the first housing and the second housing by a flange, and the sleeve is located on top of the third housing and fixed by a bracket.

[0025] 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.

[0026] Example:

[0027] Please see Figure 1 - Figure 5This embodiment of a low-flow-resistance energy-saving gate valve for a pipeline system includes a valve body, which includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are open at their relatively close ends and at the top. The first housing 1 and the second housing 2 are connected by a flange to form a bottom valve body housing with an open top. The connection between the first housing 1 and the second housing 2 by the flange also facilitates the disassembly and assembly of the first housing 1 and the second housing 2.

[0028] The valve body also includes a third housing 3 with a bottom opening. The third housing 3 is placed on top of the first housing 1. The third housing 3 is fixed to the first housing 1 and the second housing 2 by a flange, forming the housing structure of the entire valve body.

[0029] Furthermore, such as Figure 3 As shown, a filling block 13 is provided inside the third housing 3. The filling block 13 is fixed to the inner wall of the third housing 3. The screw 9 is slidably inserted through the filling block 13 to seal the top port of the third housing 3, preventing dust and other debris from falling from the third housing 3 onto the support base 6 and affecting the rotation and other operations of the screw 9.

[0030] It should be noted that, in order to improve the sealing between the housings, sealing gaskets can be provided along the edges of the first housing 1, the second housing 2, and the third housing 3, so that the first housing 1, the second housing 2, and the third housing 3 can be installed and fixed to seal the connection.

[0031] like Figure 1 and Figure 2 As shown, both ends of the valve body (i.e., the ends of the first housing 1 and the second housing 2 that are relatively far apart) are connected to connecting pipes 4. A screw 9 is provided inside the top of the valve body (i.e., the third housing 3). A sleeve 10 is connected to the top of the screw 9 by a threaded nut. The sleeve 10 is fixed to the inside of the valve body (i.e., the third housing 3) by a bracket. When the screw 9 rotates, the screw 9 can be raised and lowered inside the valve body by the action of the nut inside the sleeve 10. In order to facilitate the rotation of the screw 9, a handle 11 is installed on the top of the screw 9.

[0032] like Figure 4 and Figure 5As shown, an annular support seat 6 is provided below the screw 9. The support seat 6 is located at the bottom of the valve body, with the ends of the support seat 6 corresponding to the relatively close ends of the first housing 1 and the second housing 2, respectively. The two ends of the support seat 6 are located in the relatively close ends of the first housing 1 and the second housing 2, respectively. The ends of the support seat 6 abut against the port of the connecting pipe 4. An annular groove 5 is provided on the inner wall of the support seat 6, and a slot 7 is provided on the top of the support seat 6. The slot 7 is connected to the annular groove 5. A gate plate 8 is provided in the annular groove 5. The top of the gate plate 8 passes through the slot 7 and is rotatably connected to the bottom of the screw 9. When the screw 9 rotates, it can drive the gate plate 8 to rise and fall in the annular groove 5, thereby controlling the opening and closing of the support seat 6, which serves as a water flow channel.

[0033] Furthermore, to ensure that the gate 8 can stably fall back into the slot 7 after detaching from it, such as... Figure 3 As shown, limit seats 12 are provided on both sides above the support base 6. The frontal projection of the limit seats 12 is located on both sides of the gate plate 8. The limit seats 12 are fitted with the side of the gate plate 8 with clearance. The limit seats 12 are fixed to the inner wall of the first housing 1 to limit the lifting and lowering movement of the gate plate 8 and ensure the stability of the gate plate 8.

[0034] It should be noted that sealing gaskets are installed on the inner wall of the annular groove 5 and the inner wall of the slot 7 to improve the airtightness of the gate 8 after it is placed in the annular groove 5, preventing water from flowing out from the gap between the gate 8 and the annular groove 5 or the gap between the gate 8 and the slot 7. In addition, an elastic rubber ring is provided on the end of the support 6 so that when the support 6 is placed in the first housing 1 and the second housing 2, the end of the support 6 can fully abut against the port of the connecting pipe 4 to ensure the airtightness between the support 6 and the connecting pipe 4, so that the water passing through the valve body can only flow through the support 6.

[0035] When water flows into connecting pipe 4, such as Figure 2 and Figure 4 As shown, both ends of the support base 6 are provided with rotating shafts 14. One end of the rotating shaft 14 is rotatably mounted on the connecting base 15. The side of the connecting base 15 is fixed to the inner wall of the support base 6 through the connecting frame 16. The other end of the rotating shaft 14 is provided with several spaced spiral blades 18. The spiral blades 18 are inclined and the outer wall of the spiral blades 18 is clearance-fitted with the inner wall of the connecting pipe 4. A connecting rod 19 is installed on the inner side of the spiral blades 18 and is fixed on the rotating shaft 14. When the rotating shaft 14 rotates, the spiral blades 18 will rotate along the inner wall of the connecting pipe 4, thereby scraping the material on the inner wall of the connecting pipe 4, reducing the scale and rust on the inner wall of the connecting pipe 4, thereby reducing the obstruction of water flow by scale and rust.

[0036] Specifically, when the gate 8 is raised to allow water to pass through the valve body, the water flow impacts the spiral blades 18. The spiral shape and inclined arrangement of the spiral blades 18 allow them to rotate along the inner wall of the connecting pipe 4. This not only isolates the water flow from the inner wall of the connecting pipe 4, reducing contact between the water and the inner wall, but also scrapes away scale and rust adhering to the inner wall of the connecting pipe 4. Furthermore, the rotation of the spiral blades 18 also acts in the reaction of the water flow, causing the water flow to also form a spiral flow tendency, thereby accelerating the flow of water within the valve body and allowing the water to flow more quickly.

[0037] Furthermore, a strip plate 20 is installed on the side of the connecting rod 19. The length direction of the strip plate 20 is set along the radial direction of the rotating shaft 14. As the spiral blade 18 rotates, the strip plate 20 will also rotate, thereby pushing the water flow and improving the progress of the water flow forming a spiral flow trend.

[0038] It should be noted that a connecting sleeve 17 is installed on the end of the rotating shaft 14 away from the connecting seat 15. The connecting sleeve 17 is detachably installed on the rotating shaft 14, and the connecting rod 19 is fixed on the outer wall of the connecting sleeve 17, so that the spiral blade 18 and the rotating shaft 14 can be detachably installed. Combined with the easy disassembly setting between the housings, it is convenient to inspect and replace components such as the spiral blade 18.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
