Description

Technical Field

[0001] The present invention belongs to the technical field of valve control equipment for heating systems, and particularly relates to a multi-functional valve. Background Art

[0002] With the gradual improvement of the urban environment, residents have put forward higher requirements for the comfort of winter heating. In order to improve the thermal energy utilization efficiency and enhance the heating satisfaction of residents, a household heating system has been adopted in some current buildings. However, due to the differences in the locations and structures of residential buildings, the thermal energy required for different residential buildings to reach the standard indoor heating temperature is inconsistent. For example: corner households and middle households, sunny sides and shady sides, top floors and middle floors, brick-concrete structures and monolithic cast-in-place structures, with and without external wall insulation.

[0003] In actual life, in order to meet their own heating needs, user residents install a circulation pump in their own heating pipeline to accelerate the heat circulation in the pipeline, so as to improve the heating capacity. Privately installing a circulation pump not only affects the balance of the entire heating system, resulting in poor heating effects for other users, but also easily causes damage to heating facilities during the installation process, causing indoor or outdoor pipeline rupture, resulting in a large amount of water loss in the pipeline and wasting water resources. In the existing heating system, the water flow situation and pipeline damage situation in the pipeline cannot be monitored in real time, and it is impossible to prevent users from privately installing circulation equipment, thus affecting the stability of the overall heating system.

[0076] Central processing component, which is electrically and signal-connected to detection component 3, sensing component 5, and execution component respectively. By receiving the detection data of detection component 3 and the signals of sensing component 5, it performs analysis and processing and issues instructions to the execution component;

[0077] A signal transmitting component, which is electrically and signal - connected to the central processing component and wirelessly and signal - connected to an external terminal at the same time, and sends the status of the pipeline and the working status between other components analyzed and processed in the central processing component to the terminal.

[0078] A detection component 3, which is arranged inside the water inlet pipe of the heating system and is electrically and signal - connected to the control component 2;

[0079] The detection component 3 includes:

[0080] A flow rate detection component 301, which is arranged in the water inlet pipe and the return water pipe of the heating system and detects the water flow rate data in the water inlet pipe and the return water pipe;

[0082] The flow rate detection component 301 is a flow rate detection sensor;

[0083] An acoustic wave detection component 302, which is arranged in the water inlet pipe and the return water pipe of the heating system and detects the acoustic wave data in the water inlet pipe and the return water pipe;

[0084] The acoustic wave detection component 302 is electrically and signal - connected to the control component 2.

[0085] The acoustic wave detection component 302 is an acoustic wave detection sensor;

[0086] A check valve component 4, which is arranged at the return water pipe of the heating system and is electrically and signal - connected to the control component 2;

[0087] The check valve component 4 is a mechanical check valve device. A mechanical check valve device is installed on the return water pipe. When the return water pressure is lost, the control component 2 controls the check valve device to close automatically.

[0088] An induction component 5, which is arranged on the valve component 1 and is electrically and signal - connected to the control component 2;

[0089] The induction component 5 is an electromagnetic induction device;

[0090] Through the above - mentioned technical solution, the technical effects generated in the embodiments of the present application are:

[0091] The flow detection component 3 and the acoustic wave detection component 3 detect the water flow rate in the pipeline and the acoustic wave data in the water flow. When the water flow rate suddenly increases, the flow detection component 3 sends a signal to the control component 2, and the control component 2 controls the valve component 1 to close the water inlet pipe of the heating system. At the same time, the control component 2 controls the check valve component 4 to close synchronously. At this time, the control component 2 sends a status message to the terminal for the manager to verify the pipeline condition until the pipeline returns to normal. The manager restarts the valve component 1 and the check valve component 4 by attaching the management card to the induction component 5, enabling the valve component 1 and the check valve component 4 to open;

[0092] When the pipeline bursts, the water flow velocity in the pipeline increases, and the water flow contains intense acoustic waves generated by the pipeline burst. When the acoustic wave detection component 302 detects abnormal acoustic waves, it sends an acoustic wave signal to the control component 2. At the same time, the flow detection component 301 sends a signal to the control component 2. After receiving the signals detected by the acoustic wave detection component 302 and the flow detection component 301, the control component 2 determines that the pipeline has burst, controls the valve component 1 and the check valve component 4 to close, and sends a status message to the terminal for the manager to verify the pipeline condition and perform repairs until the pipeline returns to normal. The manager restarts the valve component 1 and the check valve component 4 by attaching the management card to the induction component 5, enabling the valve component 1 and the check valve component 4 to open;

[0093] By detecting the water flow rate and the water flow acoustic wave data in the pipeline, it is possible to determine whether there is a situation of damaging the heating system pipeline, and the detection is more real-time and accurate; by using the valve component 1 and the check valve component 4 to cut off the water inlet pipe and the water return pipe of the heating system in a timely manner, water resource waste is avoided, and at the same time, it is convenient for the manager to perform repairs and inspections; it provides a basis for avoiding water resource waste and real-time monitoring of the heating system.

[0098] The liquid inlet component 1012 is specifically a connector and is connected to the water inlet pipe of the heating system;

[0099] Liquid outlet component 1013, which is arranged on one side of the main body component 101, is arranged opposite to the liquid inlet component 1012, and its liquid outlet pipe penetrates through the main body component 101 to the installation cavity 1011;

[0100] The liquid outlet component 1013 is specifically a connector structure, which is connected to the water inlet pipe of the heating system;

[0101] Overflow component 1014, which is arranged on one side of the liquid outlet component 1013 of the main body component 101, is located above the liquid outlet component 1013, and its overflow pipe penetrates through the main body component 101 to the installation cavity 1011;

[0102] The overflow component 1014 is specifically a connector structure, which is connected to the water inlet pipe of the heating system;

[0103] Control channel 1015, which is arranged inside the main body component 101, its liquid inlet end is connected to the liquid inlet pipe, and its liquid outlet end is connected to the bottom of the installation cavity 1011;

[0104] A displacement component 10151 is arranged at the liquid outlet end of the control channel 1015;

[0105] Control component 2, which is arranged inside the main body component 101 and is connected to the sensing component 5;

[0106] Interruption component 6, which is arranged on the control channel 1015 and is connected to the control component 2;

[0107] The interruption component 6 is a valve structure, which controls the on-off of the water flow in the control channel 1015;

[0108] The first groove 1016 is arranged on the installation cavity 1011 and corresponds to the liquid outlet end of the liquid inlet component 1012 in position;

[0109] The second groove 1017 is arranged on the installation cavity 1011 and corresponds to the liquid inlet end of the liquid outlet component 1013 in position;

[0110] The third groove 1018 is arranged at the top of the installation cavity 1011, and a fixing component 10181 is arranged inside it;

[0111] Piston assembly 1020, which is arranged inside the installation cavity 1011 and has a drain channel 10202 inside it;

[0112] The fourth groove 10201 is arranged around the piston assembly 1020;

[0113] The limiting component 1021 is disposed within the installation cavity 1011, and is located between the overflow channel and the liquid outlet channel;

[0114] The limiting component 1021 is used to limit the rising height of the piston component 1020;

[0115] The elastic component 1019 is disposed between the piston component 1020 and the fixing component 10181, and its two ends are respectively connected to the piston component 1020 and the fixing component 10181.

[0116] Through the above technical solutions, the technical effects generated in the embodiments of the present application are as follows:

[0117] In the initial state (the valve component 1 is in the closed state), the interruption component 6 is in the closed state, the displacement component 10151 is located in the control channel 1015, and the top of the displacement component 10151 is flush with the bottom of the installation cavity 1011; the piston component 1020 is located at the bottom of the installation cavity 1011, and the fourth groove 10201 corresponds to the position of the first groove 1016. At this time, the piston component 1020 blocks the liquid outlet channel; the liquid in the heating system flows into the installation cavity 1011 through the liquid inlet component 1012, fills the space between the fourth groove 10201 and the first groove 1016 of the piston component 1020, and fills the space between the interruption component 6 in the control channel 1015 and the liquid inlet channel, and cannot reach the liquid outlet channel;

[0118] When the valve component 1 is opened, the interruption component 6 is opened, the liquid in the water inlet pipe of the heating system enters the control channel 1015, and pushes up the displacement component 10151 in the control channel 1015. The displacement component 10151 moves upward, causing the piston component 1020 to move upward. The piston component 1020 contacts the limiting component 1021. At this time, the positions of the first groove 1016 and the fourth groove 10201 shift, and the fourth groove 10201 coincides with the positions of the first groove 1016 and the second groove 1017 at the same time. The elastic component 1019 is retracted, and the liquid overflowing from the control channel 1015 enters the installation cavity 1011 above the piston component 1020 through the liquid discharge channel 10202 of the piston component 1020, flows out from the overflow channel, and the liquid entering from the liquid inlet component 1012 sequentially passes through the first groove 1016, the fourth groove 10201 and the second groove 1017 and flows out from the liquid outlet component;

[0119] When the valve component 1 is closed, the interruption component 6 is closed, the liquid in the control channel 1015 cannot continue to be transmitted to the installation cavity 1011, the liquid below the piston component 1020 flows out from the overflow channel through the liquid discharge channel 10202, and the piston component 1020 falls under the action of its own gravity and the elastic force of the elastic component 1019, causing the displacement component 10151 to fall and return to the initial state.

[0120] The control component 2 is adopted to control the opening and closing states of the interruption component 6, and further control the opening and closing of the valve component 1, which makes the operation more convenient and the operation more stable, and can control the water flow state of the water inlet pipe faster, providing a basis for avoiding waste of water resources.

[0121] Refer to the attached Figures 3 - 5 As shown, in a certain embodiment of the present application, the interruption component 6 is of a combined structure, including:

[0127] A first thread assembly 6021 and a second thread assembly 6022 are arranged on the rotating component 602;

[0128] The thread directions of the first thread assembly 6021 and the second thread assembly 6022 are opposite;

[0129] The rotating component 602 is of a lead screw structure, and threads in opposite directions are arranged thereon;

[0130] A supporting component 607, which is symmetrically arranged in the control channel 1015, is located on both sides of the rotating component 602, and a chute is arranged thereon;

They are connected to the chutes of the support member 607 through the protrusion blocks, enabling the first sliding member 603 and the second sliding member 604 to slide along the axial direction of the support member 607. The first sliding member 603 and the second sliding member 604 are respectively in threaded engagement with the rotating member 602. By rotating the rotating member 602, the first sliding member 603 and the second sliding member 604 move in opposite directions.

[0141] A limit groove assembly 10154 is provided in the control channel and corresponds to the first closing member 605 and the second closing member 606 in position.

[0142] The first closing member 605 and the second closing member 606 are specifically plate-like structures, which are used to close the control channel 1015. Through the relative movement of the first slider member 603 and the second sliding member, the first closing member 605 and the second closing member 606 make relative movements to simulate the opening and closing actions of a valve. The sealing performance is improved by providing the sealing assemblies.

[0143] Through the above technical solutions, the technical effects generated in the embodiments of the present application are as follows:

[0144] The driving component 601 performs forward and reverse rotation operations by receiving the instruction signal sent by the control component 2. When the interruption component 6 needs to be in the on state, the driving component 601 starts to rotate forward, driving the rotating component 602 to rotate, causing the first slider component 603 and the second slider component 604 to move upward and downward respectively, and then driving the first closing component 605 and the second closing component 606 to move towards the limit groove assembly 10154 above and below the control channel respectively, thereby completing the opening of the interruption component 6; when the interruption component 6 needs to be in the off state, the control component 2 controls the driving component 601 to reverse, causing the first slider component 603 and the second slider component 604 to move downward and upward respectively, and then causing the first closing component 605 and the second closing component 606 to contact, completing the closing action;

[0145] The first closing component 605 and the second closing component 606 are controlled to perform opening and closing actions by means of threaded connection, with higher stability during the movement process. Controlled by the control component 2, the operation is more convenient, and the control channel 1015 of the interruption component 6 can be quickly closed, and the water inlet pipe of the heating system can be timely closed, effectively avoiding the waste of water resources.
