[0001] The utility model relates to the technical field of balancing valves, in particular to a balancing valve with a protective structure. Background Art

[0002] A balancing valve is a valve with a special function. The valve itself has no special features, but its use and location are different. In some industries, due to the large pressure difference or flow difference between the media in various parts of the pipeline or container, in order to reduce or balance the difference, a valve is installed between the corresponding pipelines or containers to adjust the relative balance of pressure on both sides, or to achieve flow balance by diversion. This valve is called a balancing valve.

[0003] In the prior art, for example, Chinese patent publication number CN221504091U discloses a balancing valve with a protective structure, comprising a valve body and a valve stem. The valve body defines a valve cavity, the valve stem is connected to the valve body via a connecting flange, and extends through the valve body and is fixedly connected to a regulating valve core within the valve body. A rotary knob is provided at the top of the valve stem, and pipe connection flanges are provided on both sides of the valve body and communicate with the valve body. The pipe connection flanges are provided with a buffer mechanism, and a protective mechanism is movably provided on the valve body. This utility model belongs to the technical field of balancing valves, and specifically relates to a balancing valve with a protective structure.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that the valve stem of the traditional balancing valve is easily damaged or corroded during use and cannot be protected, resulting in damage to the valve stem, which requires manual replacement, which is very troublesome and reduces the protectiveness of the balancing valve. In addition, in places with large vibrations, the valve body cannot be shock-absorbing, which reduces the practicality of the balancing valve. Utility Model Content

At this time, the limit column limits the movement of the two protective covers to prevent the two protective covers from idling. By continuously turning the knob, the two protective covers gradually close to protect the valve stem. When it is needed, the staff reverses the knob to separate the two protective covers, and then uses the valve stem, thereby preventing the valve stem from mechanical damage or corrosion during use. It can protect it and avoid damage to the valve stem without frequent manual replacement. It is very simple and improves the protection of the balancing valve.

[0029] 2. In the utility model, when the valve body as a whole vibrates, the damper located below the two connecting pipes reduces the vibration of the structure or mechanical equipment caused by external forces or internal factors. This is very important for improving the working efficiency and extending the service life of the equipment. The two springs can absorb the impact force and convert it into elastic potential energy, reducing the impact of vibration and impact on the system. Previously, the vertical plate has been fixed to the wall, so that the valve body can be shock-absorbing in places with large vibrations, thereby improving the practicality of the balancing valve.

[0036] 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.

[0037] Example 1, please refer to Figures 1-4 The utility model provides a technical solution: a balancing valve with a protective structure, comprising a valve body 1; a flat plate 102, fixedly arranged on the outer surface of the valve body 1, and two square grooves 105 are provided at the top of the flat plate 102 near the edge; a bidirectional threaded screw rod 106, movably connected to the inner wall of one of the square grooves 105; a limiting column 107, fixedly connected to the inner wall of the other square groove 105; two protective covers 103, threadedly connected to the outer surface of the bidirectional threaded screw rod 106, and the two protective covers 10 3 is movably sleeved on the outer surface of the limit column 107; the knob 111 is movably connected to one side of the outer surface of the flat plate 102, and one side of the knob 111 is fixedly connected to one end of the bidirectional threaded screw 106. The outer surface of the valve body 1 is fixedly connected to a hollow column 108, and the inner part of the hollow column 108 is movably connected to a round shaft 109. The outer surface of the round shaft 109 is fixedly connected to the valve stem 104. Both ends of the valve body 1 are fixedly connected to the connecting pipe 101, and one side of the outer surface of the connecting pipe 101 is fixedly connected to the flange 110.

[0038] When the valve stem 104 is in operation, the staff can manually turn the knob 111 to separate the two protective covers 103, and then use the valve stem 104. This can prevent the valve stem 104 from being mechanically damaged or corroded during use, and can protect it from being damaged. There is no need for frequent manual replacement, which is very simple and improves the protection of the balancing valve.

[0039] Example 2, as Figures 1-4 As shown, the outer surfaces of the two connecting tubes 101 are fixedly connected to dampers 203, the outer surfaces of the two connecting tubes 101 are fixedly connected to springs 204, the bottom ends of the two dampers 203 are fixedly connected to horizontal plates 202, the tops of the two horizontal plates 202 are fixedly connected to the bottom ends of the two springs 204, one side of the outer surface of the horizontal plate 202 is fixedly connected to a vertical plate 2, and two threaded holes 201 are provided on one side of the outer surface of the vertical plate 2.

[0040] In this embodiment, when the valve body 1 vibrates as a whole, the damper 203 located below the two connecting pipes 101 reduces the vibration of the structure or mechanical equipment caused by external forces or internal factors, which is very important for improving the working efficiency and extending the service life of the equipment. The two springs 204 can absorb the impact force and convert it into elastic potential energy, reducing the impact of vibration and impact on the system. Previously, the vertical plate 2 has been fixed to the wall, so that the valve body can be shock-absorbing in places with large vibrations, thereby improving the practicality of the balancing valve.

[0041] Working principle: When in use, in order to protect the valve stem 104, the staff manually turns the knob 111. When the knob 111 is turned, the two-way threaded screw rod 106 is driven to rotate forward. As the two-way threaded screw rod 106 continues to rotate forward, the two protective covers 103 on the surface of the two-way threaded screw rod 106 begin to move toward the direction of the valve stem 104. At this time, the limit column 107 limits the movement of the two protective covers 103 to prevent the two protective covers 103 from idling. By continuously turning the knob 111, the two protective covers 103 are gradually closed to protect the valve stem 104. When it is needed, the staff reverses the knob 111 to separate the two protective covers 103, and then uses the valve stem 104 to open the valve stem 104. When in use, the valve stem 104 is prevented from mechanical damage or corrosion, and can be protected to avoid damage to the valve stem. There is no need for frequent manual replacement, which is very simple and improves the protection of the balancing valve. The damper 203 located under the two connecting pipes 101 reduces the vibration of the structure or mechanical equipment due to external forces or internal factors when the valve body 1 vibrates as a whole. This is very important for improving the working efficiency of the equipment and extending its service life. The two springs 204 can absorb the impact force and convert it into elastic potential energy, reducing the impact of vibration and impact on the system. The vertical plate 2 has been fixed to the wall before, so that the valve body can be shock-absorbing in places with large vibrations, thereby improving the practicality of the balancing valve.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
