Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically to a gas water heater distributor with high-precision flow control. Background Technology

[0002] Gas proportional valves have on / off and pressure-stabilizing functions. By controlling different input currents to the proportional coil, the pressure flowing through the valve body changes, thus achieving proportional pressure regulation. Currently, the conventional method for supplying gas to gas water heaters involves using proportional valves and distributors for gas delivery control and distribution. However, this method cannot achieve multi-stage combustion, failing to adequately meet the water temperature requirements of gas water heater users. Furthermore, existing proportional valves and distributors are separate units, posing a risk of gas leakage at the connection points during installation. In addition, existing gas water heater distributors struggle to achieve precise multi-stage control of the gas entering the combustion chamber, easily leading to gas waste and poor combustion uniformity.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a gas transmission control device [CN202222698157.9], which includes a proportional valve, a segmented transmission module, and a distributor; the proportional valve is used to regulate and control the gas flow; the input end of the segmented transmission module is connected to the output end of the proportional valve for segmented transmission of the gas delivered by the proportional valve; the input end of the distributor is connected to the output end of the segmented transmission module, and the distributor is equipped with several nozzles.

[0004] The above solution has solved to some extent the problem that proportional valves and distributors in the prior art are prone to gas leakage and cannot meet the outlet water temperature requirements. However, the solution still has many shortcomings, such as: it is difficult to achieve multi-stage precise control of the gas entering the combustion chamber, which can easily lead to gas waste and poor combustion uniformity. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a large-capacity, high-efficiency gas water heater distributor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gas water heater distributor with high-precision flow control, including an inlet pipe, an inlet control main valve connected to the inlet pipe via a guide pipe, an inlet solenoid valve at one end of the inlet pipe connected to the guide pipe, a gas manifold structure connected to the upper end of the inlet control main valve, an inlet control mechanism at both ends of the gas manifold structure, and a distribution chamber assembly connected to the upper end of the gas manifold structure, wherein the inlet control mechanism controls the inlet volume of each gas distribution chamber of the distribution chamber assembly respectively.

[0007] In the aforementioned high-precision flow control gas water heater distributor, the intake solenoid valve, intake control mechanism, and intake control main valve are connected to the main control module via signal control lines and connected to the power supply module via power supply circuits. The main control module is connected to the main control operation platform, and the main control operation platform is connected to the mobile terminal via a wireless module.

[0008] In the aforementioned high-precision flow control gas water heater distributor, the gas manifold structure includes an access pipe whose inlet size is controlled by an inlet control valve. The access pipe is connected to a horizontally arranged gas manifold cavity, and both ends of the gas manifold cavity are closed.

[0009] In the aforementioned high-precision flow control gas water heater distributor, a return pipe is provided between the gas manifold and the inlet pipe, and a return gas inlet pipe is provided on one side of the gas inlet pipe. The return pipe is connected to the return gas inlet pipe through a return gas guide pipe to realize the return delivery of gas.

[0010] In the above-mentioned high-precision flow control gas water heater distributor, the distribution cavity assembly includes a gas distribution pipe, and a plurality of gas diversion chambers are arranged on the inner side of the gas distribution pipe, and adjacent gas diversion chambers are mutually isolated.

[0011] In the aforementioned high-precision flow control gas water heater distributor, a number of gas exhaust holes corresponding to the gas diversion chambers are provided on one side of the gas distribution pipe.

[0012] In the aforementioned high-precision flow control gas water heater distributor, a number of diversion air inlet chambers are provided on one side of the gas manifold, corresponding one-to-one with the gas diversion chambers. The diversion air inlet chambers and the gas diversion chambers are interconnected through a gas guide channel.

[0013] In the aforementioned high-precision flow control gas water heater distributor, the air intake control mechanism includes an air intake control solenoid valve disposed on the lower side of the gas manifold, the output end of which extends into the diversion air intake chamber and the end is sealed at one end of the gas guide channel.

[0014] In the aforementioned high-precision flow control gas water heater distributor, the output end of the gas inlet control solenoid valve has a telescopic plug, and the upper surface of the telescopic plug has a sealing groove into which one end of the gas guide channel can be inserted.

[0015] In the aforementioned high-precision flow control gas water heater distributor, a wiring circuit board is provided on the back of the gas distribution pipe, and fixed mounting plates are connected to both ends of the gas distribution pipe.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: Firstly, the intake solenoid valve and intake control master valve enable precise control of the incoming gas volume. Secondly, the telescopic plug design of the intake control solenoid valve allows for independent and precise adjustment of the intake volume in each gas distribution chamber, preventing excessive gas supply and reducing energy waste. Thirdly, the distribution chamber assembly employs several mutually isolated gas distribution chambers, each supplied with gas through an independent gas distribution chamber and guide channel. Combined with the precise control of the intake control mechanism, this ensures uniform gas distribution in each chamber. Finally, a return pipe and a return gas inlet pipe are installed between the gas manifold and the intake pipeline, allowing underutilized gas to return to the intake pipeline for recirculation, reducing gas loss during transmission and distribution and improving energy efficiency.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4As shown, a high-precision flow control gas water heater distributor includes an inlet pipe 1, which is connected to an inlet control main valve 12 via a gas guide pipe 11. An inlet solenoid valve 13 is installed at one end of the inlet pipe 1 connected to the gas guide pipe 11. A gas manifold structure 2 is connected to the upper end of the inlet control main valve 12. Inlet control mechanisms 3 are installed at both ends of the gas manifold structure 2, and a distribution chamber assembly 4 is connected to the upper end of the gas manifold structure 2. The inlet control mechanisms 3 respectively control the inlet volume of each gas distribution chamber 41 of the distribution chamber assembly 4.

[0024] Gas enters the system through the intake pipe 1, and after passing through the intake solenoid valve 13 at the connection end of the intake pipe 1 and the guide pipe 11, it is delivered to the intake control valve 12 by the guide pipe 11. The intake control valve 12 achieves preliminary control of the total amount of gas entering the gas manifold structure 2 by adjusting the size of the intake port of the access pipe 21. The gas after being adjusted by the intake control valve 12 enters the horizontally arranged gas manifold 22 through the access pipe 21. At the same time, the remaining gas in the gas manifold 22 that is not immediately distributed is delivered to the return gas access pipe 24 on the side of the intake pipe 1 through the return pipe 23 and the return guide pipe, realizing the return circulation of unused gas and reducing losses.

[0025] Among them, the intake solenoid valve 13, the intake control mechanism 3, and the intake control master valve 12 are connected to the master control module 5 through the signal control line and connected to the power supply module 51 through the power supply circuit. The master control module 5 is connected to the master control operation platform 52, and the master control operation platform 52 is connected to the mobile terminal 53 through the wireless module.

[0026] The central control module 5 receives instructions from the central control operation platform 52 or remote instructions from the mobile terminal 53 via a wireless module, coordinating the actions of various components in real time to achieve dynamic and precise control of the total gas volume and the air intake of each branch chamber, adapting to different combustion requirements.

[0027] As can be seen, the gas manifold structure 2 includes an access pipe 21 whose size of the air inlet is controlled by the main air inlet control valve 12. The access pipe 21 is connected to a gas manifold 22 arranged horizontally, and both ends of the gas manifold 22 are closed.

[0028] Obviously, a return pipe 23 is provided between the gas manifold 22 and the inlet pipe 21, and a return gas inlet pipe 24 is provided on one side of the gas inlet pipe 1. The return pipe 23 is connected to the return gas inlet pipe 24 through the return gas guide pipe to realize the return delivery of gas.

[0029] Furthermore, the distribution cavity assembly 4 includes a gas distribution pipe 42, and a plurality of the aforementioned gas diversion chambers 41 are arranged circumferentially inside the gas distribution pipe 42, with adjacent gas diversion chambers 41 being mutually isolated.

[0030] Furthermore, one side of the gas distribution pipe 42 is provided with several gas exhaust holes 43 that correspond to the gas diversion chamber 41.

[0031] Specifically, a number of gas diversion chambers 25 are provided on one side of the gas manifold duct 22, which correspond one-to-one with the gas diversion chambers 41. The gas diversion chambers 25 and the gas diversion chambers 41 are interconnected through the gas guide channel 44.

[0032] Each gas distribution chamber 41 has a corresponding gas exhaust port 43 on one side. After the gas is precisely regulated, it enters the gas distribution chamber 41 and is evenly discharged into the combustion chamber through the gas exhaust port 43 to ensure uniform combustion.

[0033] More specifically, the intake control mechanism 3 includes an intake control solenoid valve 31 disposed on the lower side of the gas manifold duct 22. The output end of the intake control solenoid valve 31 extends into the split intake chamber 25 and the end is sealed at one end of the guide passage 44.

[0034] In detail, the output end of the intake control solenoid valve 31 has a telescopic plug 32, and the upper surface of the telescopic plug 32 has a sealing groove 33 into which one end of the air guide channel 44 can be inserted.

[0035] The output end of the intake control solenoid valve 31 extends into the split intake chamber 25. Its telescopic plug 32 can be adjusted up and down after being energized. Together with the sealing groove 33 on the upper end face, it can precisely control the opening and closing degree of the gas guide channel 44, thereby independently adjusting the amount of gas entering each split intake chamber 25 into the corresponding gas split chamber 41.

[0036] Preferably, a wiring circuit board 34 is provided on the back of the gas distribution pipe 42, and a fixed mounting plate 45 is connected to both ends of the gas distribution pipe 42.

[0037] In summary, the principle of this embodiment is as follows: after the gas enters through the intake pipe 1, the total intake volume is first regulated by the intake solenoid valve 13 and the intake control master valve 12, and then collected through the gas manifold 22; unused gas is recycled through the return pipe 23 to reduce losses. The collected gas is transported through the diversion intake chamber 25 and the guide channel 44, which correspond one-to-one with each independent gas diversion chamber 41. The opening and closing degree is precisely controlled by the telescopic plug 32 of the intake control mechanism 3 to achieve independent and precise control of the intake volume of each gas diversion chamber 41.
