Description

Technical Field

[0001] This utility model relates to the field of energy supply technology, specifically to a self-adjustable energy distributor for pipeline networks. Background Technology

[0002] During the winter heating season in northern China, most cities use a heat metering system for heating. The municipal heating network is typically designed to use main pipelines to transport hot water to residential areas and then distribute it to each household.

[0003] Residents often adjust the inlet valves according to their needs, which can easily cause pressure fluctuations in the heating pipes within the community. These pressure fluctuations not only affect the heating flow to individual users, leading to unstable indoor temperatures, but also negatively impact the entire community's heating system. To ensure the stable operation of the heating system and prevent users' heating flow from being disturbed by pressure fluctuations, heating companies have to allocate a large amount of manpower to frequently manually adjust the opening of the inlet valves in residential communities. At the same time, traditional heating systems lack effective real-time monitoring and centralized management methods, making it difficult for heating companies to keep track of the pressure, temperature, and other operating parameters of each node in the pipeline network in real time, and to detect potential problems in a timely manner, such as local pipe blockages and uneven heat distribution. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a self-adjustable energy distributor for pipeline networks, which solves the problems of pipeline pressure fluctuations caused by residents adjusting their inlet valves during winter heating in northern regions, high costs of manual adjustment, and difficulties in management.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-adjustable energy distributor for pipeline networks, comprising: a housing, a pressure measuring device fixedly connected to the inner wall of the housing, the pressure measuring device utilizing elasticity for pressure release, an adjusting device fixedly connected to the inner wall of the housing, and a display fixedly connected to the outer wall of the housing. The pressure measuring device includes a first valve body, a sleeve fixedly connected to the input end of the first valve body, a valve core slidably connected to the inner wall of the sleeve, and the outer walls of the first valve body and the sleeve fixedly connected to the inner wall of the housing. This energy distributor, equipped with a pressure measuring device and an adjusting device, can achieve automatic adjustment of pipeline network flow.

[0008] Preferably, a compression spring is fixedly connected to the outer wall of the valve core via a limiting plate, a diaphragm is fixedly connected to the top of the valve core and the compression spring, and a valve cover is fixedly connected to the top of the diaphragm. The diaphragm in the pressure measuring device cooperates with the compression spring to accurately collect changes in pipeline pressure. When the pipeline pressure fluctuates, the pressure change causes the diaphragm to shift, which in turn moves the valve core and changes the pressure discharge state of the first valve body.

[0009] Preferably, the limiting plate at the bottom of the compression spring is fixedly connected to the inner wall of the valve cover, and the outer wall of the valve cover is fixedly connected to the inner wall of the housing. When residents arbitrarily adjust the inlet valve, causing fluctuations in the pipeline pressure, the pressure measuring device responds quickly and transmits the pressure change to the regulating device through the linkage of the valve core and the diaphragm.

[0010] Preferably, the regulating device includes a second valve body, with a valve stem rotatably connected to the inner wall of the second valve body. A regulating valve is fixedly connected to the bottom end of the valve stem. When the pipeline pressure fluctuates, the pressure change causes the diaphragm to shift, which in turn moves the valve core, changing the pressure discharge state of the first valve body. The regulating device operates according to the pressure signal transmitted by the pressure measuring device. The actuator drives the valve stem to rotate, thereby driving the regulating valve to adjust its opening and automatically regulating the pipeline flow.

[0011] Preferably, the input end of the second valve body is fixedly connected to the output end of the first valve body through a pipe, and the output end of the second valve body is fixedly connected to the inner wall of the housing through a pipe. The outer wall of the regulating valve is rotatably connected to the inner wall of the second valve body. The regulating device reacts quickly, adjusts the opening of the regulating valve, and accurately controls the fluid flow rate, effectively avoiding the impact of pressure fluctuations on the user's heating flow rate and ensuring the heating quality of residents.

[0012] Preferably, an actuator is rotatably connected to the top of the valve stem, and the outer wall of the actuator is fixedly connected to the top of the housing.

[0013] Beneficial effects

[0014] This invention provides a self-adjustable energy distributor for pipeline networks. It offers the following advantages:

[0015] This utility model, through the coordinated use of a pressure measuring device and a regulating device, utilizes a diaphragm and compression spring in the pressure measuring device to accurately collect changes in pipeline pressure. When the pipeline pressure fluctuates, the pressure change causes the diaphragm to shift, moving the valve core and altering the pressure discharge state of the first valve body. The regulating device operates based on the pressure signal transmitted by the pressure measuring device, with the actuator driving the valve stem to rotate, thereby adjusting the opening of the regulating valve and automatically regulating the pipeline flow. Compared to the traditional method of manually adjusting the opening of inlet valves in residential communities, this significantly reduces manual intervention and effectively lowers the labor costs for heating companies. The display on the surface of the unit not only visually shows the working status of the energy distributor but also has the function of collecting pressure and temperature signals.

[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] Example

[0023] Please see Figure 1-4 This utility model provides a technical solution: a self-adjustable energy distributor for pipeline networks, comprising:

[0024] The enclosure 1 has a pressure measuring device 2 fixedly connected to its inner wall. The pressure measuring device 2 uses elasticity to release pressure. The inner wall of the enclosure 1 has an adjustment device 3 fixedly connected to its inner wall. The outer wall of the enclosure 1 has a display fixedly connected to its outer wall. In use, the network tube is connected to the enclosure 1. The pressure measuring device 2 and the adjustment device 3 are adjusted according to the pressure of the network tube.

[0025] The pressure measuring device 2 includes a first valve body 20, with a sleeve 21 fixedly connected to the input end of the first valve body 20. A valve core 22 is slidably connected to the inner wall of the sleeve 21. The outer walls of the first valve body 20 and the sleeve 21 are fixedly connected to the inner wall of the housing 1. First, the sleeve 21 at the input end of the first valve body 20 in the pressure measuring device 2 is connected to the pipeline network. When the pipeline network pressure changes, the pressure acts on the diaphragm 24 connected to the valve core 22. Since the top of the diaphragm 24 is fixedly connected to the valve cover 25, and the valve cover 25 is fixed to the housing 1, the diaphragm 24 is displaced under the pressure.

[0026] A compression spring 23 is fixedly connected to the outer wall of the valve core 22 via a limiting plate. A diaphragm 24 is fixedly connected to the top of the valve core 22 and the compression spring 23. A valve cover 25 is fixedly connected to the top of the diaphragm 24. The limiting plate at the bottom of the compression spring 23 is fixedly connected to the inner wall of the valve cover 25. The outer wall of the valve cover 25 is fixedly connected to the inner wall of the housing 1. At the same time, the compression spring 23 connected to the outer wall of the valve core 22 via the limiting plate undergoes elastic deformation when the diaphragm 24 is displaced. The diaphragm 24 and the compression spring 23 cooperate with each other to convert the change in pipeline pressure into the movement of the valve core 22, thereby changing the pressure discharge state of the first valve body 20. This process accurately collects the pipeline pressure change signal, providing a basis for subsequent adjustment.

[0027] The regulating device 3 includes a second valve body 30, a valve stem 31 rotatably connected to the inner wall of the second valve body 30, a regulating valve 32 fixedly connected to the bottom end of the valve stem 31, an input end of the second valve body 30 fixedly connected to the output end of the first valve body 20 via a pipe, an output end of the second valve body 30 fixedly connected to the inner wall of the housing 1 via a pipe, and an outer wall of the regulating valve 32 rotatably connected to the inner wall of the second valve body 30. The regulating device 3 regulates the flow rate according to the pressure signal transmitted by the pressure measuring device 2. The output end of the first valve body 20 is connected to the input end of the second valve body 30 via a pipe. When the pressure measuring device 2 detects a pressure change and transmits a signal, the actuator 33 is activated. The actuator 33 is rotatably connected to the top end of the valve stem 31. After activation, it drives the valve stem 31 to rotate, and the regulating valve 32 fixed at the bottom end of the valve stem 31 rotates accordingly, changing the opening degree of the regulating valve 32 within the second valve body 30.

[0028] An actuator 33 is rotatably connected to the top of the valve stem 31. The outer wall of the actuator 33 is fixedly connected to the top of the housing 1. When the pipeline pressure rises, the pressure measuring device 2 causes the valve core 22 to move, and the signal is transmitted to the regulating device 3. The actuator 33 drives the valve stem 31 to reduce the opening of the regulating valve 32, thereby reducing the flow rate of the pipeline fluid. Conversely, when the pipeline pressure decreases, the opening of the regulating valve 32 increases, thereby increasing the flow rate. In this way, the pipeline flow rate is automatically adjusted according to the pressure change.

[0029] When in use, connect the official website to the housing 1, and adjust the pressure measuring device 2 and the regulating device 3 according to the pressure of the network pipe;

[0030] First, the sleeve 21 at the input end of the first valve body 20 in the pressure measuring device 2 is connected to the pipeline network. When the pipeline network pressure changes, the pressure acts on the diaphragm 24 connected to the valve core 22. Since the top of the diaphragm 24 is fixedly connected to the valve cover 25, and the valve cover 25 is fixed to the housing 1, the diaphragm 24 is displaced under the pressure.

[0031] Meanwhile, the compression spring 23 connected to the outer wall of the valve core 22 via the limiting plate undergoes elastic deformation when the diaphragm 24 is displaced. The diaphragm 24 and the compression spring 23 cooperate to convert the change in pipeline pressure into the movement of the valve core 22, thereby changing the pressure discharge state of the first valve body 20. This process accurately collects the pipeline pressure change signal, providing a basis for subsequent adjustment.

[0032] The regulating device 3 regulates the flow rate based on the pressure signal transmitted by the pressure measuring device 2. The output end of the first valve body 20 is connected to the input end of the second valve body 30 through a pipeline. When the pressure measuring device 2 detects a pressure change and transmits a signal, the actuator 33 is activated. The actuator 33 is rotatably connected to the top of the valve stem 31. After activation, it drives the valve stem 31 to rotate, and the regulating valve 32 fixed at the bottom of the valve stem 31 rotates accordingly, changing the opening degree of the regulating valve 32 in the second valve body 30.

[0033] When the pipeline pressure increases, the pressure measuring device 2 causes the valve core 22 to move, and the signal is transmitted to the regulating device 3. The actuator 33 drives the valve stem 31 to reduce the opening of the regulating valve 32, thereby reducing the flow rate of the pipeline fluid. Conversely, when the pipeline pressure decreases, the regulating valve 32 opens more, thereby increasing the flow rate. In this way, the pipeline flow rate is automatically adjusted according to the pressure change.

[0034] During equipment operation, the display collects signals such as pressure and temperature inside the energy distributor in real time. These signals not only visually show the equipment's working status for easy viewing by on-site staff, but also upload them to the host computer via data transmission lines. After receiving the data, the host computer allows heating company staff to centrally monitor and manage the entire pipeline network.
