Description

Technical Field

[0001] This invention relates to the field of water distributor technology, and more specifically, to an H-type water distributor for heating and cooling. Background Technology

[0002] In heating and cooling systems, the core function of a water distributor is to evenly distribute incoming water to multiple branch pipes to meet the multi-zone temperature control needs of scenarios such as building heating, industrial heat exchange, or containerized energy stations. However, as the scale of the system expands (such as large commercial buildings and distributed energy networks), the number of branch pipes that the water distributor needs to connect to increases significantly.

[0003] When applied to building and boiler heating scenarios, i.e., heating for urban users, the traditional method often uses two independent tanks to store hot water and cold water separately to ensure that the hot water and cold water supply do not interfere with each other and avoid mixing of the two, which would make it difficult to control the temperature accurately. Therefore, most of them now use H-type water distributors; an H-type water distributor consists of one inlet pipe and multiple distribution pipes.

[0004] When using an H-type water distributor, because the inlet pipe connects to multiple pipes, the water itself has a certain inertia during the water delivery process. This can easily cause the water to enter the branch pipe in the same direction as the inlet pipe faster than the branch pipe in the opposite direction, resulting in inconsistent water flow rates in the bidirectional branch pipes. This situation makes it impossible to achieve uniform water distribution, which will seriously affect the uniformity and stability of heating or cooling. Therefore, we propose an H-type water distributor for heating and cooling. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an H-type water distributor for heating and cooling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an H-type water distributor for heating and cooling, comprising an inlet pipe, two symmetrical guide pipes connected to the outside of the inlet pipe, detection components connected to both ends of the two guide pipes, and a diversion pipe connected to one end of each detection component;

[0007] The detection assembly includes a control valve, a connecting pipe installed on one side of the control valve, and an installation pipe vertically installed at the bottom of the connecting pipe. A spring and a pressure sensor are installed inside the installation pipe. A rubber plug is installed at the top of the spring, and a pressure rod is installed at the bottom of the rubber plug.

[0008] Preferably, the outer wall of the rubber stopper is in contact with the inner wall of the mounting tube, and both the pressure sensor and the pressure rod are located inside the spring, with the pressure rod corresponding to the pressure sensor.

[0009] Preferably, a drain pipe is installed on one side of the installation pipe, a valve is provided at the bottom of the drain pipe, a connecting shaft is connected inside the connecting pipe, a water wheel is installed outside the connecting shaft, and a sealing ring is installed inside the connecting pipe and outside the connecting shaft.

[0010] Preferably, a gear is mounted on one end of the connecting shaft that extends through and to the outside of the connecting tube, and a mounting base is mounted on the outside of the connecting tube.

[0011] Preferably, a guide rod is installed inside the mounting base, and a spring is installed on one side of the mounting base outside the guide rod.

[0012] Preferably, a rack is externally connected to the guide rod, one end of the second spring is connected to the rack, the rack meshes with the teeth of the gear, and a counter is installed on the outer side of the mounting base.

[0013] Preferably, a pressure rod is installed on one side of the bottom of the rack, and a pressure sensor is installed on one side of the mounting base corresponding to the position of the pressure rod.

[0014] Preferably, a second ear plate is installed on one side of the connecting pipe, and a first ear plate is connected to both the control valve and the second ear plate. Two symmetrical mounting cylinders are installed inside the two first ear plates, and a connecting rod is connected inside the mounting cylinders.

[0015] Preferably, a handle and a bolt are installed at both ends of the connecting rod, with the handle located outside the mounting cylinder and the bolt located inside the mounting cylinder. Two symmetrical threaded grooves are opened on the outer side of both the control valve and the second ear plate, and the bolt is adapted to the threaded grooves.

[0016] The technical effects and advantages of this invention are as follows:

[0017] When in use, this invention uses the pressure sensors built into the four detection components to monitor the water flow status in real time. When the pressure sensors of all branches detect the pressure signal, the system synchronously opens the four control valves through the controller to ensure that water enters the branch pipes at the same time. This device forces water to enter all branch pipes at the same time, eliminates the flow deviation caused by inertia, and solves the problem of uneven heating and cooling.

[0018] In use, this invention utilizes a water turbine to drive a single-tooth gear to rotate. Each rotation of the gear triggers the rack once, which in turn generates a pulse signal by pressing the pressure sensor. A counter records the number of pulses per unit time, and the water flow velocity is calculated by combining the gear circumference, making it easier for staff to observe the water flow.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] As attached Figures 1-8 The H-type water distributor for heating and cooling shown includes an inlet pipe 1, and two symmetrical guide pipes 2 are connected to the outside of the inlet pipe 1. Both ends of the two guide pipes 2 are connected to detection components 3, and one end of each detection component 3 is connected to a diversion pipe 4.

[0030] The detection assembly 3 includes a control valve 31, a connecting pipe 32 installed on one side of the control valve 31, an installation pipe 34 vertically installed at the bottom of the connecting pipe 32, a spring 35 and a pressure sensor 36 installed inside the installation pipe 34, a rubber plug 37 installed at the top of the spring 35, a pressure rod 33 installed at the bottom of the rubber plug 37, the outer wall of the rubber plug 37 is in contact with the inner wall of the installation pipe 34, the pressure sensor 36 and the pressure rod 33 are both located inside the spring 35, and the pressure rod 33 corresponds to the pressure sensor 36, a drain pipe 38 installed on one side of the installation pipe 34, a valve 39 installed at the bottom of the drain pipe 38, a connecting shaft 310 connected inside the connecting pipe 32, a water wheel 311 installed outside the connecting shaft 310, and a sealing ring 312 installed inside the connecting pipe 32 and outside the connecting shaft 310.

[0031] The end of the pressure rod 33 contacts the pressure sensor 36 built into the spring 35, which is used to detect the water flow status in real time through pressure. When the pressure sensor 36 is squeezed, it means that the water flow in the pipeline has arrived, which facilitates the opening of multiple control valves 31. When multiple pressure sensors 36 detect pressure, multiple control valves 31 open simultaneously. Subsequently, valve 39 can be opened to drain the water in the installation pipe 34, which is convenient for continued detection. The sealing ring 312 increases the tightness between the connecting shaft 310 and the connecting pipe 32.

[0032] A gear 313 is installed at one end of the connecting shaft 310, extending through and to the outside of the connecting tube 32. A mounting base 314 is installed on the outside of the connecting tube 32. A guide rod 315 is installed inside the mounting base 314. A spring 316 is installed on one side of the inside of the mounting base 314 and outside the guide rod 315. A rack 317 is connected to the outside of the guide rod 315. One end of the spring 316 is connected to the rack 317. The rack 317 meshes with the teeth of the gear 313. A counter 327 is installed on one side of the outside of the mounting base 314. A pressure rod 318 is installed on one side of the bottom of the rack 317. A pressure sensor 319 is provided on one side of the inside of the mounting base 314 and at the position corresponding to the pressure rod 318.

[0033] When the water wheel 311 rotates, it drives the gear 313 to rotate through the connecting shaft 310. The gear 313 has only one tooth. The gear 313 can mesh with the rack 317 in one rotation cycle, so that the pressure rod 318 squeezes the pressure sensor 319. Then, the spring 316 resets the pressure rod 318 squeezes the pressure sensor 319 multiple times, and the counter 327 calculates the pressing value. At this time, the water flow speed in one of the pipes can be detected.

[0034] A second ear plate 321 is installed on one side of the connecting pipe 32. A first ear plate 320 is connected to one side of both the control valve 31 and the second ear plate 321. Two symmetrical mounting cylinders 322 are installed inside the two first ear plates 320. A connecting rod 323 is connected inside the mounting cylinder 322. A handle 324 and a bolt 325 are installed at both ends of the connecting rod 323. The handle 324 is located outside the mounting cylinder 322, and the bolt 325 is located inside the mounting cylinder 322. Two symmetrical threaded grooves 326 are opened on the outer side of both the control valve 31 and the second ear plate 321. The bolt 325 is adapted to the threaded groove 326.

[0035] Both ends of the control valve 31 are provided with lugs, and can be detached and connected to the guide pipe 2 and the diverter pipe 4 through the two lugs 320. Both lugs 320 are fixed by bolts 325 and threaded grooves 326. The bolts 325 can be located inside the mounting sleeve 322 to prevent the bolts 325 from being lost.

[0036] Working principle of this invention: When applied to building and boiler heating scenarios, i.e., for urban users' heating; water source flows from inlet pipe 1, and the water flow is split into four detection components 3 through symmetrical guide pipe 2. At this time, control valve 31 is in the closed state. When the water flow reaches the detection point installation pipe 34, the water flow applies pressure to rubber plug 37 and compresses spring 35, causing the end of pressure rod 33 to squeeze pressure sensor 36 built into spring 35, triggering a pressure signal. When all four pressure sensors 36 detect pressure, the system determines that all branch water flow has arrived, and opens the four control valves 31 synchronously through the controller to ensure that the diversion pipe 4 enters water at the same time, avoiding flow distribution deviation due to opening and closing time difference;

[0037] When the water flows normally, it impacts the water wheel 311 when passing through the connecting pipe 32, driving the connecting shaft 310 and gear 313 to rotate (gear 313 has only one tooth, triggering a detection once per revolution). When gear 313 rotates, it meshes with rack 317, pushing rack 317 along guide rod 315 to compress spring 316, causing pressure rod 318 to squeeze pressure sensor 319 to generate a pulse signal. When gear 313 does not mesh with rack 317, spring 316 resets, rack 317 returns to its original position, waiting for the next trigger. Counter 327 records the number of pulses per unit time and calculates the water flow velocity by combining it with the circumference of gear 313.

[0038] After the water supply is completed, open the valve 39 at the bottom of the drain pipe 38. The residual water in the installation pipe 34 is discharged under gravity. At this time, the rubber plug 37 is reset by the setting of spring 35, which facilitates the next test.

[0039] When it is necessary to disassemble the testing component 3, rotate the handle 324 to drive the connecting rod 323 to rotate, so that the bolt 325 is disengaged from the threaded groove 326; the bolt 325 is always located in the mounting sleeve 322 to avoid loss; through the bolt 325 connection structure between the ear plate 1 320 and the ear plate 2 321, any testing component 3 can be disassembled individually for maintenance or replacement.

[0040] Finally, the following points should be noted: First, in the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can refer to mechanical connection or electrical connection, or internal connection between two components, or direct connection.
