Description

Technical Field

[0001] This utility model relates to the field of pipeline valve assembly technology, and more specifically to an integrated low water resistance pipeline valve assembly system for equipment outlet. Background Technology

[0002] The energy consumption of heating, ventilation, and air conditioning systems in buildings accounts for approximately 40%-60% of the total building energy consumption, and improving their energy efficiency has become a key breakthrough for building energy conservation.

[0003] In existing equipment (such as refrigeration units and water pumps) outlet pipe systems, pipes are directly connected perpendicularly to horizontal pipes at 90° right angles, with tees used for flow connections and Y-type filters. The high local resistance coefficients of these pipe fittings and filters increase system energy consumption. The installation of valve assemblies in the equipment outlet pipes involves pipe fabrication (beveling, pipe welding, flange welding, pipe joint fabrication), support installation, pipe installation, and valve and instrument installation, requiring a step-by-step construction process and resulting in a long overall construction period. Low-resistance valves and filters are widely used in HVAC and other fields. However, they are not integrated into the equipment outlet pipe valve assemblies; many levels use only one type of low-resistance component, leading to insignificant reductions in fluid resistance and energy consumption.

[0004] Therefore, how to provide a pipe valve assembly system that can reduce water resistance and thus reduce the energy consumption of HVAC systems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an integrated low water resistance pipeline valve group system for equipment outlet, which reduces water flow resistance, optimizes fluid dynamics performance, and reduces energy consumption by setting an included angle between the main connecting pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated low-water-resistance pipeline valve assembly system for equipment outlets includes:

[0008] support frame

[0009] The main body is fixed to the support frame;

[0010] A connecting pipe, the first end of which is connected to the inner cavity of the main pipe; the angle between the axis of the connecting pipe and the axis of the main pipe is 40 to 60°.

[0011] An outlet pipe, the first end of which is fixed to the second end of the connecting pipe; the second end of the outlet pipe is connected to a device;

[0012] A valve assembly comprising a plurality of low-flow-resistance valves and fixed to the connecting pipe;

[0013] An instrument assembly, which is fixed to the connecting pipe or the outlet pipe.

[0014] The beneficial effects of this utility model are that the main pipe, connecting pipe, and outlet pipe are assembled with the support frame using a prefabrication method. On the construction site, installation can be achieved simply by connecting the outlet pipe to the equipment and then hoisting the support frame to the embedded plate on the building's roof. This avoids the cumbersome on-site pipe connection and makes construction efficient and quick. The outlet pipe of the connecting equipment and the main pipe used for fluid transportation are connected by an inclined connecting pipe. By replacing the traditional right-angle elbow with the connecting pipe, water flow resistance can be reduced, fluid dynamics performance can be optimized, and kinetic energy loss during fluid turning can be reduced, thereby reducing water resistance and lowering the energy consumption of the equipment.

[0015] Preferably, the number of main pipes is at least two, which are a water supply pipe and a water return pipe respectively; the number of connecting pipes is at least two, which are respectively connected to the water supply pipe and the water return pipe one-to-one; the valve assembly includes a butterfly valve, and the butterfly valve is fixed on the pipe of the connecting pipe near the main pipe. The butterfly valve controls the opening and closing of the connection between the connecting pipe and the water supply pipe, and between the connecting pipe and the water return pipe.

[0016] Preferably, the instrument assembly includes a temperature gauge and a pressure gauge, and at least one temperature gauge and one pressure gauge are fixed to the connecting pipe or the outlet pipe. The temperature and pressure of the fluid in the connecting pipe or the outlet pipe are monitored by the temperature gauge and the pressure gauge.

[0017] Preferably, the system further includes a filter, which is fixed to the connecting pipe connected to the water supply pipe; pressure gauges are provided at both ends of the filter, with one pressure gauge fixed to the connecting pipe corresponding to the filter and the other pressure gauge fixed to the outlet pipe corresponding to the filter. The filter can filter impurities in the water supply pipe, and the pressure changes of the fluid at both ends of the filter are monitored by the two pressure gauges to determine whether the filter is clogged due to impurity accumulation.

[0018] Preferably, the valve assembly further includes an electrically adjustable valve; the electrically adjustable valve is fixed to the connecting pipe between the filter and the butterfly valve. The electrically adjustable valve is capable of regulating the flow rate of fluid entering the water supply pipe.

[0019] Preferably, the system also includes a drain pipe, one end of which is fixed to an outlet pipe connected to the water supply pipe; the drain pipe is equipped with a switch valve. The drain pipe can relieve pressure and discharge waste from inside the boiler.

[0020] Preferably, a rubber flexible joint and a reducing straight pipe are fixed to the second end of the outlet pipe in sequence, and the reducing straight pipe is connected to the equipment outlet.

[0021] Preferably, the support frame includes a frame and a support column; the main pipe is snapped onto the frame; one end of the support column is vertically fixed to the top surface of the frame, and the other end can be fixed to the building's roof slab. Fixing the main pipe to the building's top using the support column allows for more efficient use of space and a more compact pipe layout.

[0022] Preferably, the device further includes a pipe support, which comprises a support plate and a U-shaped clip. The support plate is fixed to the top surface of the frame, and its upper side surface has a groove for accommodating the main pipe. The U-shaped clip is fastened to the support plate by a pin to confine the main pipe within the groove. The support plate and U-shaped clip secure the main pipe to the frame, ensuring the proper installation of the main pipe.

[0023] Preferably, the connecting pipe and the outlet pipe are connected by a connector pipe at a 90-120° angle.

[0024] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an integrated low water resistance pipeline valve group system for equipment outlet. The equipment outlet pipe and the main pipe are connected by a 40-60° connecting pipe, which reduces the kinetic energy loss when the fluid turns, thereby reducing water resistance and reducing equipment energy consumption.

Detailed Implementation

[0031] 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.

[0032] Participate in the attached Figures 1 to 4 An integrated low-water-resistance pipeline valve assembly system for equipment outlet according to an embodiment of the present invention includes a support frame 1, a main pipe 2, a connecting pipe 3, an outlet pipe 4, a valve assembly 5, and an instrument assembly 6; the support frame 1 is fixed to the building roof; the main pipe 2 is fixed on the support frame 1, and... Figure 2 As shown, the main pipe 2 is a horizontal pipe, serving as the main pipeline for fluid transport; the first end of the connecting pipe 3 connects to the inner cavity of the main pipe 2; the angle between the axis of the connecting pipe 3 and the axis of the main pipe 2 is 40-60°, and the connecting pipe 3 is an inclined pipe, with its inclination angle preferably 45°; by replacing the right-angle bend in the traditional pipeline layout with an inclined connecting pipe, turbulence and pressure loss can be reduced, and the kinetic energy loss during fluid turning can be reduced, with measured water resistance reduced by 30%-50%; the first end of the outlet pipe 4 is fixed to the second end of the connecting pipe 3; the outlet pipe... The second end of 4 is connected to the equipment; the outlet pipe 4 is also arranged horizontally, and the first end of the outlet pipe 4 is welded and fixed to the second end of the connecting pipe 3 by a joint pipe with an angle of 90-120° and an inner diameter of 1.5 times that of the inner diameter of the connecting pipe 3; the valve assembly 5 includes multiple low flow resistance valves and is fixed on the connecting pipe 3; the low flow resistance valve cap is preferably a full-bore valve to ensure that the inner diameter of the flow channel is consistent with the pipe, avoid the narrowing effect, and reduce the local resistance coefficient of the pipe; the instrument assembly 6 is fixed on the connecting pipe 3 or the outlet pipe 4 to monitor the temperature, pressure and other indicators of the fluid in the pipe.

[0033] To further optimize the above technical solution, the number of main pipes 2 is at least two, which are water supply pipes and return pipes respectively; the number of connecting pipes 3 is at least two, which are respectively connected to the water supply pipes and return pipes one by one; the valve assembly 5 includes a butterfly valve 51, and the butterfly valve 51 is fixed on the pipe of the connecting pipe 3 near the end of the main pipe 2.

[0034] like Figure 1As shown, this embodiment has four main pipes arranged side by side, namely a cooling water inlet pipe, a cooling water return pipe, a chilled water inlet pipe, and a chilled water return pipe; the equipment includes a condenser and an evaporator, and the equipment corresponds to four outlet pipes. The inlet and outlet of the condenser are respectively connected to the cooling water return pipe and the cooling water supply pipe, and the inlet and outlet of the evaporator are respectively connected to the chilled water return pipe and the chilled water supply pipe; each connecting pipe has at least one butterfly valve.

[0035] Considering factors such as building interior space, insulation, maintenance, and operation, BIM technology is used for comprehensive and detailed layout design. Modular designs are flexibly adjusted based on equipment outlet locations and the overall building layout to ensure efficient space utilization and rational pipe routing. Support frames, main pipes, connecting pipes, and valve assemblies are all prefabricated and assembled in the factory according to the design. On-site adjustments are only required to the support frame position, and the outlet pipe is connected to the equipment via flanges after alignment. This reduces on-site welding and cutting work, simplifying the construction process and improving installation efficiency. Compared to traditional on-site pipe installation methods, this integrated assembly method only requires connecting the equipment outlet and fixing the support frame, increasing construction efficiency by 50% while reducing high-altitude work procedures, making construction safer and more efficient. After prefabrication and assembly in an integrated manner, on-site installation only requires connecting to the equipment and welding or bolting the support frame to the embedded parts in the building's roof slab.

[0036] To further optimize the above technical solution, the instrument assembly 6 includes a temperature gauge 61 and a pressure gauge 62; at least one temperature gauge 61 and one pressure gauge 62 are fixed on the connecting pipe 3 or the outlet pipe 4.

[0038] To further optimize the above technical solution, a filter 7 is also included. The filter 7 is fixed on the connecting pipe 3 connected to the water supply pipe. Pressure gauges 62 are provided at both ends of the filter 7, and one pressure gauge 62 is fixed on the connecting pipe 3 corresponding to the filter 7, and the other pressure gauge 62 is fixed on the outlet pipe 4 corresponding to the filter 7.

[0039] To further optimize the above technical solution, valve assembly 5 also includes an electric regulating valve 52; the electric regulating valve 52 is fixed on the connecting pipe 3 between filter 7 and butterfly valve 51.

[0040] Electric regulating valves are also full-bore low-resistance valves, which can ensure that the inner diameter of the pipe is synchronized with the inner diameter of the flow channel, reduce the local resistance coefficient of the pipe, and thus reduce the energy consumption of the equipment.

[0041] In this embodiment, a filter is installed on the connecting pipe connected to the water supply pipe, while no filter is installed on the connecting pipe connected to the return water pipe. The connecting pipe with the filter is equipped with two pressure gauges and one temperature gauge. The two pressure gauges are located at both ends of the filter and on the connecting pipe and the outlet pipe, respectively. The connecting pipe without the filter is equipped with one pressure gauge and one temperature gauge. This compact layout makes reasonable use of space.

[0042] In other specific embodiments, the first end of the connecting pipe is fixedly connected to the side wall of the main pipe by welding. The second end of the outlet pipe 4 is sequentially fixed with a rubber expansion joint 41 and a reducing straight pipe 42. The reducing straight pipe 42 is connected to the equipment outlet via a flange. A sealing test is required at the connection flange between the outlet pipe 4 and the equipment outlet to prevent leakage. After the reducing straight pipe is connected to the equipment outlet, the first end of the outlet pipe 4 is welded to the second end of the connecting pipe 3. In this embodiment, the pipes are welded together, allowing for factory prefabrication and on-site installation. This integrated approach improves the installation efficiency of the piping system.

[0043] To further optimize the above technical solution, a drain pipe 8 is also included, one end of which is fixed to the outlet pipe 4 connected to the water supply pipe; a switch valve is provided on the drain pipe 8.

[0044] In other specific embodiments, the support frame 1 adopts a steel bracket, including a frame 11 and a support column 12; the main pipe 2 is snapped onto the frame 11; one end of the support column 12 is vertically fixed to the top surface of the frame 11, and the other end can be fixed to the roof slab of the building. A steel plate is welded to the end of the support column 12 away from the frame 11, and the steel plate is welded or bolted to the embedded plate on the roof slab of the building.

[0045] To further optimize the above technical solution and ensure the installation effect of the main pipe, a pipe support 13 is also included. The pipe support 13 includes a support plate 131 and a U-shaped clip 132. The support plate 131 is fixed to the top surface of the frame 11, and a placement groove for accommodating the main pipe 2 is opened on the upper side of its plate surface. The U-shaped clip 132 is fastened to the support plate 131 by a pin to restrict the main pipe 2 in the placement groove.

[0046] In other embodiments, the height of the support frame and the tilt angle of the connecting pipe can be customized according to the interior space of the building to adapt to different equipment outlet layouts.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments.
