Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a valve body capable of weakening water hammer effect. Background Art

[0002] The definition of valve body is a device used to control the direction, pressure and flow of fluid in a fluid system. Valve is a device that allows the medium in pipes and equipment to flow or stop and control its flow.

[0003] The valve body can stop the flow of liquid in the pipeline. When the liquid stops flowing, the water hammer effect will occur. Water hammer is also called water shock. During the water transportation process, the flow rate changes suddenly due to the sudden closure of the valve and other reasons, and the pressure fluctuates greatly. Because the inner wall of the water pipe is smooth, the water flows freely. When the open valve is suddenly closed, the water flow will have a large impact force on the valve and the pipe wall, mainly the valve. This impact force can easily cause the valve to leak, and in severe cases, it may even cause damage to the valve or the pipe wall. Based on this, a valve body that can weaken the water hammer effect is studied. Utility Model Content

[0030] Embodiment 1

[0031] like Figure 1-3 As shown, this embodiment provides a valve body capable of weakening the water hammer effect, which comprises:

[0032] A pipe body 1, with connecting flanges 3 fixedly connected on both sides of the pipe body 1;

[0033] The valve plate 4 is rotatably located in the pipe body 1 for blocking the pipe body 1. In the present embodiment, the valve plate 4 is a circular plate-shaped structure, a half of which is provided with a plurality of groups of reduction holes 8, and a control handle 9 for controlling the rotation of the valve plate 4 is provided on the outer wall of the tank body;

[0034] It also includes a sealing plate 7 for sealing the reduction hole 8. The sealing plate 7 is rotatably arranged on the side of the water-facing surface of the valve plate 4 along the center line of the valve plate 4. A rotating rod 6 for controlling the rotation of the sealing plate 7 is arranged on the outer wall of the pipe body 1.

[0035] In some embodiments, the control handle 9 and the rotating rod 6 can be integrated or independent, and it can achieve the purpose of controlling the rotation of the valve plate 4 and the rotating rod 6 on the outer wall of the tube body 1 .

[0036] In actual use, the control handle 9 is screwed in advance to close the valve plate 4. After the valve plate 4 rotates, it closes the inside of the pipe body 1 to a certain extent, and part of the water continues to flow through the reduction hole 8. Under the action of the reduction hole 8, the water flow continues to flow, which weakens the water hammer effect caused by part of the water when the valve plate 4 is closed, and avoids the valve plate 4 from being damaged by the water hammer effect; then the rotating rod 6 is rotated, and the rotating rod 6 drives the sealing plate 7 to rotate and fit on the valve plate 4 to block the reduction hole 8. Under the action of water pressure, the sealing plate 7 is pushed tightly against the valve plate 4, thereby achieving the overall closure of the pipeline. Through the cooperation between the valve plate 4 and the sealing plate 7, most of the water hammer effect is eliminated through the reduction hole 8 in the process of closing the valve plate 4 first. When the sealing plate 7 closes the reduction hole 8, the impact force brought by the remaining small amount of water will not impact the sealing plate 7 too heavily, avoiding the sealing plate 7 from being damaged by impact.

[0037] In some embodiments, a hollow rotating shaft 5 is commonly connected between the valve plate 4 and the rotating handle, and the above-mentioned rotating rod 6 is rotatably arranged inside the hollow rotating shaft 5. A rotating notch 51 is opened on the hollow rotating shaft 5 located inside the tube body 1, and the rotating notch 51 is specifically opened at the center position inside the tube body 1. The rotating rod 6 is connected to the sealing plate 7 through the rotating notch 51 to drive the sealing plate 7 to rotate.

[0038] In some embodiments, the sealing plate 7 is a fan-shaped structure, which further facilitates the rotation of the sealing plate 7 in the tube body 1, and the fan-shaped structure can further fit the valve plate 4 to block the reduction hole 8, avoiding leakage of the reduction hole 8 after blocking.

[0039] In some embodiments, a sealing strip 10 is connected to one side or both sides of the sealing plate 7, and the sealing strip 10 can further prevent water from entering between the valve plate 4 and the sealing plate 7 and then leaking out from the reduction hole 8; at the same time, the sealing strip 10 can also play a buffering and anti-wear role to a certain extent, avoiding direct collision between the sealing plate 7 and the valve plate 4, causing damage or deformation thereof.

[0040] In some embodiments, a detection mechanism 2 is also provided on the pipe body 1 for measuring the water flow rate, water quality and water pressure. The detection mechanism 2 can be an independent water pressure tester, a water flow sensor and a water quality detector, or a device integrating the three. The detection mechanism 2 measures the condition of the water in the water pipe and displays it on a display screen, so that the staff can quickly know the current condition of the water in the pipe body 1.

[0041] Embodiment 2

[0042] like Figure 4-5 As shown, this embodiment provides a valve body that can weaken the water hammer effect, and other structures are the same as those of the first embodiment. The only difference is that in this embodiment, the rotating rod 6 is designed as a hidden type to maintain a certain aesthetics.

[0043] Its specific structure is that the rotating rod 6 includes a bottom rod 61 and a top rod 62. The bottom rod 61 is provided with a guide groove 63. The bottom outer wall of the top rod 62 is connected with a protrusion 64. The protrusion 64 is slidably arranged along the guide groove 63. When the protrusion 64 is located at the bottom of the guide groove 63, the top surface of the top rod 62 and the top surface of the hollow rotating shaft 5 are in the same plane.

[0044] refer to Figure 5 In some embodiments, the guide groove 63 is a circular groove, and rectangular grooves connected to the circular groove are arranged on both sides of the circular groove, and the protrusion 64 is slidably arranged in the rectangular groove; when in use, the top rod 62 is lifted and then rotated. Under the action of the protrusion 64, the top rod 62 drives the bottom rod 61 to rotate, thereby realizing the closing of the sealing plate 7.

[0045] Furthermore, in order to prevent the top rod 62 from being lifted up too much, a limit cover 65 is provided on the top of the bottom rod 61, and a limit plate 66 is connected to the bottom of the bottom rod 61. When the top rod 62 is lifted up, the top rod 62 cannot be lifted up any further until the limit plate 66 fits against the limit cover 65.

[0046] Furthermore, a groove 52 is provided on the hollow shaft 5, and a handle 67 is fixedly connected to the top of the top rod 62, and the handle 67 can be placed in the groove 52; at the same time, both sides of the groove 52 also have arc grooves for facilitating the lifting of the handle 67.

[0047] During actual use, the valve plate 4 is first closed by rotating the control handle 9, and then the top rod 62 is lifted from the groove 52. After lifting, the top rod 62 is screwed, and the top cover drives the bottom rod 61 to rotate, and the bottom rod 61 thereby drives the sealing plate 7 connected thereto to rotate to achieve the closure of the reduction hole 8.

[0048] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
