Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building water supply network technology, specifically, it relates to a water pressure balance regulating valve for building water supply networks. Background Technology
[0002] The water pressure balancing regulating valve for building water supply networks is a crucial hydraulic control device specifically designed to address the common hydraulic imbalance problem in building water supply systems, ensuring efficient, stable, and comfortable system operation.
[0003] In complex branching pipe networks (especially in high-rise buildings and large public buildings), the pressure head (available pressure) varies greatly between water points at different distances from pumps or tanks, and between water points on different floors. This can lead to excessive water pressure for users near the source or on lower floors (wasting water, generating noise, and damaging appliances). Balancing valves compensate for pressure losses in distant / high-resistance branches by increasing the resistance of near / low-resistance branches, thus ensuring that each branch reaches its design flow rate.
[0004] However, the water pressure in the near-end / low-resistance branch is relatively high, and most existing regulating devices rely on invisible countermeasures to offset the water pressure, but this damages the components inside the regulating device and affects the service life of the device.
[0005] In view of this, this utility model is proposed. Utility Model Content

The regulating component is used to regulate the water pressure of the near-end / low-resistance branch. The regulating component includes a valve body, an extension pipe, a fixed block, and a movable block. The valve body and the extension pipe are fixedly connected. The valve body and the extension pipe are respectively connected to the corresponding pipelines. The fixed block is fixedly connected to the extension pipe, and the movable block is elastically connected to the fixed block.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] Please see Figure 1-5 A water pressure balancing regulating valve for a building water supply network includes a regulating assembly for regulating the water pressure of a near-end / low-resistance branch. The regulating assembly includes a valve body 1, an extension pipe 2, a fixed block 3, and a movable block 31. The valve body 1 and the extension pipe 2 are fixedly connected and respectively connected to corresponding pipelines. The fixed block 3 is fixedly connected to the extension pipe 2, and the movable block 31 is elastically connected to the fixed block 3. The water flow is buffered by the obstruction of the movable block 31, thereby buffering the water pressure. Under the elastic setting of the movable block 31, damage to components under hard buffering is avoided.
[0028] The fixed block 3 has a through hole in the middle, and the movable block 31 is conical in shape. The movable block 31 is in close contact with the fixed block 3. Support rods 33 are arranged around the fixed block 3. Each support rod 33 is fixedly connected to the fixed block 3, and the movable block 31 is slidably connected to the corresponding support rod 33. Each support rod 33 is fitted with a spring 34. The end of each spring 34 is fixedly connected to the support rod 33, and the other end of each spring 34 is fixedly connected to the movable block 31. When the valve body on the valve body 1 is opened, the water flow from the bottom / low resistance branch pours out. The water flows continuously and is quickly discharged after the valve body is opened. The water flow applies pressure to the movable block 31, which is pushed by the water flow and compresses the spring 34. After the movable block 31 separates from the fixed block 3, the water flows through the drain port on the movable block 31. The water flow is discharged from the fixed block 31, which buffers the water pressure. As the water pressure continues to increase and the water flow pushes the movable block 31 to continuously separate from the fixed block 3, the water flow passes through the gap between the fixed block 3 and the movable block 31. The movable block 31 buffers the water flow, thus buffering the water pressure. The elastic setting of the movable block 31 avoids damage to the components under rigid buffering. When the water flow and water pressure in the pipe decrease, the force on the movable block 31 decreases. The spring 34 applies the force generated by the deformation to the movable block 31, and the movable block 31 is pushed towards the fixed block 3. As the movable block 31 and the fixed block 3 slowly approach each other, they close, thereby sealing the inner wall of the pipe, accumulating water flow, and increasing the internal water pressure.
[0029] The fixed block 3 is surrounded by pressure relief pipes 32, each of which is fixedly connected to the corresponding fixed block 3. Each pressure relief pipe 32 has an inlet 36 facing the port of the fixed block 3 and a pressure relief port 37 facing the side wall of the movable block 31. The movable block 31 is slidably connected to the corresponding pressure relief pipe 32, and the movable block 31 has a corresponding drain port 35. When the fixed block 3 and the movable block 31 are closed, a small branch of water flows through the inlet 36 of the pressure relief pipe 32 and is discharged through the pressure relief port 37. When the movable block 31 moves slowly, it blocks the pressure relief port 37 and the small branch of water flow. When the fixed block 3 and the movable block 31 are closed or slowly closed, the water flow forms a branch through the pressure relief pipe 32 and is slowly discharged with the help of the branch water flow, so as to realize the uninterrupted water supply and avoid the occurrence of insufficient water supply in the pipeline when the water pressure is insufficient.
[0030] It is worth noting that the slow discharge of water flow branches is premised on sufficient water supply in the pipe network. When the water supply in the pipe network is insufficient, the problem of insufficient water supply is not a design flaw of this optimization scheme, and will not be elaborated here.
[0031] Working principle: When the valve body on valve body 1 is opened, water flows out from the bottom / low resistance branch. The water flows continuously and is quickly discharged after the valve body is opened. The water pressure is applied to the movable block 31, which is pushed by the water flow and compresses the spring 34. After the movable block 31 separates from the fixed block 3, the water flows out through the drain port 35 on the movable block 31. The water pressure is buffered by the obstruction of the movable block 31. When the water pressure continues to increase and the water pushes the movable block 31, the water pressure is further reduced. The movable block 31 continues to separate from the fixed block 3 until they are completely separated. Water then flows through the gap between the fixed block 3 and the movable block 31. The movable block 31 acts as a buffer, thus reducing the water pressure. Furthermore, the elastic design of the movable block 31 prevents damage to components caused by rigid buffering. When the water flow and pressure in the pipe decrease, the force on the movable block 31 decreases, and the spring 34 applies the force generated by deformation to the movable block 31. The movable block 31 moves towards the fixed block 3, and as it slowly approaches the fixed block 3, the connection between the movable block 31 and the fixed block 3 closes, thus sealing the inner wall of the pipe, accumulating water flow, and increasing the internal water pressure. With the fixed block 31 and the movable block 31 closed, a small branch of water flows through the inlet 36 of the pressure relief pipe 32 and is discharged through the pressure relief port 37 on the pressure relief pipe 32. As the movable block 31 moves slowly, it blocks the pressure relief port 37, thus preventing the small... The water flow is blocked by a branch. When the fixed block 3 and the movable block 31 are closed or slowly closed, the water flow forms a branch through the pressure relief pipe 32 and is slowly discharged through the branch, so as to achieve uninterrupted water supply and avoid insufficient water supply in the pipeline when the water pressure is insufficient. The premise of the slow discharge of the water flow branch is that the water supply in the pipeline network is sufficient. When the water supply in the pipeline network is insufficient, the problem of insufficient water supply is not a design defect of this optimization scheme and will not be elaborated here.
