Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and in particular relates to a gate valve that is easy to install. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate. The direction of the gate's movement is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. Gate valves have advantages such as low flow resistance and reduced likelihood of water hammer.

[0003] Traditional gate valve installation relies on manual support for alignment, requiring repeated adjustments to the relative positions of the gate valve and pipeline flanges, which is time-consuming and labor-intensive. This is especially true in confined spaces or high-altitude work environments, where manual alignment is even more difficult, significantly increasing installation time.

[0004] To address the aforementioned problems, this utility model document proposes a gate valve that is easy to install. Utility Model Content

[0005] The purpose of this invention is to provide a gate valve that is easy to install. By driving the positioning part to move through the extrusion assembly, the gate valve can be quickly aligned with the pipeline, reducing manual labor and eliminating the need for long-term valve support, thus effectively improving work efficiency and solving existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] An easy-to-install gate valve, used for auxiliary positioning of the gate valve during installation, includes:

[0008] The gate valve body has valve flanges fixed at both ends.

[0009] Two pipes are located at both ends of the gate valve body. Both pipes have flanges fixed to their surfaces, and the two pipe flanges are used in conjunction with the two valve flanges.

[0010] Two sets of positioning parts are located on the surfaces of two valve flanges respectively. Each set of positioning parts includes at least four compression limiting rods. A accommodating gap is formed between the four compression limiting rods for limiting and locking the pipe flange. A set of compression components is provided on the surfaces of the two valve flanges. The two sets of compression components are used to push the two sets of positioning parts to move to the surfaces of the two pipe flanges respectively.

[0011] Furthermore, in order to ensure the stability of the two sets of extrusion components, each set of extrusion components also includes a limiting component, which is used to limit the movement range of the extrusion components.

[0012] Optionally, each of the extrusion assemblies includes a fixing nut welded to the surface of the valve flange, a threaded cylinder threaded to the surface of the fixing nut, a connecting ring fixed to the side end of the threaded cylinder, and four extrusion limiting rods evenly fixed to the side end of the connecting ring, with the connecting ring slidably sleeved on the surface of the valve flange.

[0013] When the threaded cylinder rotates and moves axially on the surface of the fixed nut, it drives the connecting ring to slide on the surface of the valve flange. The connecting ring pushes the squeeze limit rod outward to the surface of the pipe flange. When the two pipe flanges are respectively located in the two sets of accommodating gaps, the gate valve body is stably positioned between the two pipes.

[0014] Optionally, each of the limiting components includes a limiting ring fixed to the side end of the threaded cylinder, a limiting gap is formed between the limiting ring and the connecting ring, and the fixing nut is located within the limiting gap;

[0015] In this process, the connecting ring or the limiting ring will eventually come into contact with the fixing nut as it moves along with the threaded cylinder. The fixing nut can prevent the threaded cylinder from detaching from the surface of the fixing nut through the connecting ring and the limiting ring.

[0016] Optionally, at least two levers are fixed to the surfaces of both threaded cylinders;

[0017] The protrusion on the lever allows for more effective rotation of the threaded cylinder, making the rotation process more convenient.

[0018] Optionally, the surfaces of all four levers are fixed with rubber sleeves.

[0019] Optionally, a semi-circular extrusion head is fixed to each of the eight extrusion limiting rods at their far ends;

[0020] Among them, the semi-circular extrusion head first makes extrusion contact with the surface of the pipe flange when the extrusion limit rod moves to the surface of the pipe flange. The surface of the semi-circular extrusion head is smooth and has a buffering effect, which can better drive the extrusion limit rod to be sleeved on the surface of the pipe flange.

[0021] Optionally, all eight of the compression limit rods are made of stainless steel.

[0022] In this application, when the threaded cylinder rotates on the surface of the fixed nut and moves axially, it drives the connecting ring to slide on the surface of the valve flange. The connecting ring pushes the squeeze limit rod outward to the surface of the pipe flange. When the two pipe flanges are respectively located in the two sets of accommodating gaps, the gate valve body is stably positioned between the two pipes.

[0023] In this utility model, the gate valve that is easy to install moves the positioning part by the extrusion assembly, so as to realize the rapid alignment of the gate valve with the pipeline, reduce the manual burden, eliminate the need to support the valve for a long time, and effectively improve work efficiency.

[0024] In this utility model, the gate valve that is easy to install has a uniformly distributed compression limit rod to form a multi-point limiting snap-fit, which ensures that the gate valve and the pipeline flange are subjected to uniform force and reduces the risk of leakage.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] Please see Figures 1-3 As shown, this embodiment provides a gate valve, including a gate valve body 1, two pipes, and two sets of positioning parts. Valve flanges 3 are fixed to both ends of the gate valve body 1, and two pipes are located at both ends of the gate valve body 1, with pipe flanges 2 fixed to their surfaces. The two sets of positioning parts are respectively disposed on the surfaces of the two valve flanges 3, used to limit and engage the pipe flanges 2.

[0036] Each positioning part includes at least four compression limiting rods 5, with a receiving gap formed between the four compression limiting rods 5 for clamping the pipe flange 2. The valve flange 3 surface is provided with a compression assembly that pushes the positioning part to the surface of the pipe flange 2. The compression assembly includes a fixing nut 9 welded to the surface of the valve flange 3, a threaded sleeve 7 threadedly connected to the surface of the fixing nut 9, a connecting ring 4 fixed to the side end of the threaded sleeve 7, and compression limiting rods 5 evenly fixed to the side end of the connecting ring 4, with the connecting ring 4 slidably sleeved on the surface of the valve flange 3.

[0037] Each set of extrusion components also includes a limiting component, which includes a limiting ring 8 fixed to the side end of the threaded cylinder 7. A limiting gap is formed between the limiting ring 8 and the connecting ring 4, and the fixing nut 9 is located within the limiting gap. When the threaded cylinder 7 rotates and moves axially, the connecting ring 4 slides on the surface of the valve flange 3, and the extrusion limiting rod 5 moves outward to the surface of the pipe flange 2. When the two pipe flanges 2 are respectively located within the two sets of accommodating gaps, the gate valve body 1 is stably positioned between the two pipes.

[0038] A semi-circular extrusion head 10 is fixed at the far end of the extrusion limiting rod 5. When the extrusion limiting rod 5 moves to the surface of the pipe flange 2, the semi-circular extrusion head 10 first makes extrusion contact with the surface of the pipe flange 2. The surface of the semi-circular extrusion head 10 is smooth and has a cushioning effect, which can better drive the extrusion limiting rod 5 to be sleeved on the surface of the pipe flange 2;

[0039] The compression limit rod 5 is made of stainless steel to ensure its durability and corrosion resistance during long-term use.
