Description

Technical Field

[0001] This utility model relates to the field of HVAC pipe control valve technology, and in particular to an adjustment structure for HVAC valves. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a component of buildings, encompassing heating, ventilation, and air conditioning. It is also a profession that trains senior engineering and management personnel to work in the fields of building environmental control, building energy conservation, and intelligent building facilities. Graduates will possess the ability to design, construct, commission, and manage public facility systems such as air conditioning, heating, ventilation, building water supply and drainage, and gas supply, as well as building thermal energy supply systems and building energy conservation, and to develop building automation system solutions.

[0003] The existing HVAC pipe control valve is installed at the connection between two pipes. If the space reserved by the worker at the connection between the two pipes is not compatible with the length of the control valve, the control valve cannot be installed to connect the two pipes. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustment structure for HVAC valves. By rotating the sleeve, the connecting pipe can be rotated and moved within the valve port under the threaded engagement, thereby changing the length of the connecting pipe extending out of the valve port. This adapts to the gap left by the worker between the valve and the pipe, improving the installation efficiency and quality of the valve body.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustment structure for a heating, ventilation, and air conditioning (HVAC) valve includes a valve body with valve ports fixedly connected to its left and right ends. Each valve port has a sleeve threadedly connected to its outer wall, and each sleeve has a connecting pipe fixedly connected to its inner wall. Each connecting pipe has a flange fixedly connected to its outer end, and each flange has an adjustment component installed at its outer end.

[0007] Furthermore, the outer wall of the connecting pipe is tightly fitted to the inner wall of the valve port, so that liquid will not leak out when the connecting pipe slides inside the valve port.

[0008] Furthermore, the adjustment assembly includes flanges fixedly connected to the outer end of the flange, each flange having a first retaining ring on its inner wall at the outer end, each first retaining ring having multiple first threaded holes at its inner end, and each first retaining ring having a first connecting member fixedly connected to its outer wall.

[0009] Furthermore, the inner wall of the flange is threaded with multiple fixing bolts to cooperate with the first threaded hole to install the first connecting piece on the flange.

[0010] Furthermore, each of the first connectors has a second retaining ring on its outer end inner wall, and each of the second retaining rings has multiple second threaded holes on its inner end. Each of the second retaining rings has a second connector fixedly connected to its outer wall.

[0011] Furthermore, the inner wall of the first connector is threaded with multiple fixing bolts to cooperate with the second retaining ring to install the second connector onto the first connector.

[0012] Furthermore, the inner wall of the second connector is threaded with multiple fixing bolts for connecting to the pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by rotating the sleeve, the connecting pipe can be rotated and moved on the inner wall of the valve port under the threaded engagement, thereby changing the length of the connecting pipe extending into the valve port, adapting to the gap left by the worker between the valve and the pipeline, and improving the installation efficiency and quality of the valve body.

[0015] 2. In this utility model, depending on the pipe diameter, the first threaded hole can be inserted into the groove on the flange, and the first connecting piece can be fixed to the flange by the first threaded hole and the fixing bolt. Alternatively, the second retaining ring on the second connecting piece can be inserted into the groove on the first connecting piece and fixed by the fixing bolt, thus making it suitable for pipes of different diameters.

[0021] 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.

[0022] Reference Figure 1-3 An embodiment of this utility model is provided: an adjustment structure for a heating and ventilation valve, including a valve body 1, valve ports 7 are fixedly connected to the left and right ends of the valve body 1, sleeves 2 are threadedly connected to the outer walls of the valve ports 7, and connecting pipes 3 are fixedly connected to the inner walls of the sleeves 2. The outer walls of the connecting pipes 3 are tightly fitted to the inner walls of the valve ports 7, so that liquid will not leak out when the connecting pipes 3 slide inside the valve ports 7.

[0023] Specifically, by rotating the sleeve 2, the connecting pipe 3 can be rotated and moved within the valve port 7 under the threaded engagement, thereby changing the length of the connecting pipe 3 extending out of the valve port 7. This adapts to the gap left by the worker between the valve and the pipeline, improving the installation efficiency and quality of the valve body 1. Since the error of the gap left between the two pipelines is normally not too large, only a few rotations of the sleeve 2 are needed to adjust the length of the connecting pipe 3 extending out of the valve port 7, allowing the connecting pipe 3 to connect with the free ends of the two pipelines. Therefore, during adjustment, there is still a large amount of thread engagement between the sleeve 2 and the valve port 7, preventing the connecting pipe 3 from shaking inside the valve port 7 due to insufficient thread engagement, which would affect the sealing performance of the valve body.

[0024] Each connecting pipe 3 is fixedly connected to a flange 4 at its outer end. Each flange 4 is provided with an adjusting assembly at its outer end. The adjusting assembly includes a flange 4 fixedly connected to the outer end of the flange 4. Each flange 4 has a first retaining ring 8 on its inner wall at its outer end. Each first retaining ring 8 has multiple first threaded holes 9 at its inner end. Each first retaining ring 8 has a first connecting piece 5 fixedly connected to its outer wall. Each flange 4 has multiple fixing bolts threadedly connected to its inner wall to cooperate with the first threaded holes 9 to install the first connecting piece 5 on the flange 4. Each first connecting piece 5 has a second retaining ring 10 on its inner wall at its outer end. Each second retaining ring 10 has multiple second threaded holes 11 at its inner end. Each second retaining ring 10 has a second connecting piece 6 fixedly connected to its outer wall. Each first connecting piece 5 has multiple fixing bolts threadedly connected to its inner wall to cooperate with the second retaining ring 10 to install the second connecting piece 6 on the first connecting piece 5. Each second connecting piece 6 has multiple fixing bolts threadedly connected to its inner wall for connection with the pipe.

[0025] Specifically, the first retaining ring 8 on the first connector 5 can be inserted into the groove on the flange 4 and fixed with fixing bolts. This allows connection to pipes with larger diameters using the remaining holes on the first connector 5. Similarly, the second retaining ring 10 on the second connector 6 can be inserted into the groove on the first connector 5. The second connector 6 can then be installed on the first connector 5 using the holes on the first connector 5 and the second threaded hole 11 on the second retaining ring 10, along with fixing bolts. The remaining holes on the second connector 6 can then be used to connect to pipes with larger diameters, thus accommodating pipes of different diameters. When the first connector 5 is installed on the flange 4 and the second connector 6 is installed on the first connector 5, the first threaded hole 9 on the first connector 5 will mate with the groove at the outward end of the flange 4, and the second retaining ring 10 on the second connector 6 will mate with the groove at the outward end of the first connector 5. This ensures that the holes used for installation are aligned and that the grooves are completely sealed, guaranteeing the sealing between the connectors.

[0026] Working principle: First, according to the pipe diameter, insert the first threaded hole 9 into the groove on the flange 4, and fix the first connecting piece 5 to the flange 4 through the first threaded hole 9 and the fixing bolt. Alternatively, insert the second retaining ring 10 on the second connecting piece 6 into the groove on the first connecting piece 5, and fix it with the fixing bolt to connect pipes with larger diameters. Then, place the valve body 1 into the gap reserved between the two pipes. If the overall length of the valve is greater than the gap, rotate one side of the sleeve 2 to drive the connecting pipe 3 to retract into the valve port 7. Then connect and fix the pipe on that side to the valve first, and then according to... The distance between the connecting pipe 3 on the other side and the other pipe is determined by rotating the sleeve 2 on the other side to extend the connecting pipe 3 and connect it to the free end of the other pipe for installation and fixation. If the length is less than the gap, the sleeve 2 on one side can be rotated in the opposite direction to extend the connecting pipe 3 to the outside of the valve port 7 and connect it to the pipe for installation. Then, the sleeve 2 on the other side can be rotated to extend the connecting pipe 3 to the outside of the valve port 7 and connect it to the other pipe for installation. This facilitates the installation of the valve body 1 and eliminates the need to disassemble and reinstall the pipe if the gap between the two pipes is not met, thus improving the overall installation efficiency of the valve.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
