Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline instruments, and particularly relates to a water supply pipeline pressure monitor. Background Technique

[0002] Water supply pipelines are the most basic configurations in urban construction and layout. After the pipeline installation is completed, in order to understand the current operating conditions of the pipeline and check the pipeline safety status, it is necessary to detect the pipeline water pressure. Usually, a water pressure detection device is used at the pipeline line detection point to detect the water flow pressure in the pipeline. Water pressure detection is used for the burst pressure determination and pressure resistance time determination of various types of pipe fittings. It is widely used in quality inspection units. Conducting water pressure detection on pipelines is an indispensable process in the pipeline manufacturing process.

[0003] The Chinese utility model patent with the publication number of CN217637773U discloses a hot water pipeline pressure monitoring device, which includes a mounting piece, a pipeline, and a pressure monitor. Connectors are arranged on both sides of the mounting piece. One side of the connector is connected to the pipeline. An airbag is arranged inside the mounting piece. A connecting rod is arranged at the top of the airbag. An adapter plate is arranged at the top of the connecting rod. A contact head is arranged at the top of the adapter plate. Return springs are arranged on both sides of the contact head. In the utility model, return springs are arranged on both sides of the contact head, and the top of the return spring is connected to the pressure monitor, which increases the stability of the monitoring. A blade is arranged inside the mounting piece, a rotating shaft is arranged inside the blade, and a flow monitor is arranged at the top of the rotating shaft, which can understand the water flow in real time and is convenient for monitoring the flow inside the pipeline.

[0004] However, there are still some deficiencies in the above-mentioned utility model:

[0005] During the use of the above-mentioned utility model, the airbag, the blade, and the monitoring thermometer are all installed inside the mounting piece. The mounting piece is connected to the pipeline through the connector. Hot water enters the mounting piece from the pipeline, and the hot water does not reach the standard of boiling water, which results in a large amount of water scale in the hot water. These water scales will adhere to the surfaces of the airbag, the blade, and the monitoring thermometer when passing through the mounting piece, and need to be cleaned regularly to avoid the water scale affecting the data monitoring. However, the airbag, the blade, and the monitoring thermometer are installed inside the mounting piece, and they are easily blocked by other components during cleaning, resulting in incomplete cleaning and reduced cleaning efficiency;

[0006] In addition, each time the installation part is cleaned, the installation part needs to be removed from the water pipe, which requires cutting off the hot water supply in the water pipe in advance. After the cleaning is completed, the installation part is reinstalled on the water pipe, which cannot ensure the continuous supply of hot water and brings inconvenience to users. In addition, when the water pressure in the installation part is too high, the airbag gives a signal to the pressure monitor to remind the staff to deal with it in time. If the staff does not deal with it in time, the pressure in the water pipe will continue to increase, and even the water pipe will burst. Summary of the Invention

[0007] The utility model provides a water supply pipeline pressure monitor, aiming to solve the problems mentioned in the above background technology.

[0008] The utility model is realized as follows: A water supply pipeline pressure monitor includes a water supply pipe. A branch pipe is arranged at the top of the side wall of the water supply pipe. A water valve is installed in the branch pipe, and the branch pipe is connected to a monitoring pipe through a flange. A sealing component is installed at the top end of the monitoring pipe. A fixed partition is fixedly connected to the inner wall of the monitoring pipe. An airbag is installed on the fixed partition. A control button is installed at the top inside the sealing component, and a signal lamp and a timer are respectively installed on the outer top of the sealing component. The control button is connected to the signal lamp and the timer through wires respectively. A pressure relief component is connected to the side wall of the monitoring pipe, and the pressure relief component is connected to the timer through a wire; in this solution, a water valve is arranged on the branch pipe. By controlling the water valve to close the channel between the branch pipe and the monitoring pipe, the monitoring pipe can be removed from the branch pipe, and the scale in the monitoring pipe can be cleaned without closing the water supply pipe channel.

[0009] Preferably, a through hole is opened at the central position of the fixed partition. The airbag is installed in the through hole, and a plug cover is arranged at the top of the airbag. The fixed partition equally divides the accommodation space inside the airbag.

[0010] Preferably, the fixed partition divides the internal space of the monitoring pipe into a monitoring space and a water injection space from top to bottom. The molecular mass of the gas injected into the airbag is greater than that of air, and the volume of the gas injected into the airbag is 1 / 2 - 2 / 3 of the total volume of the airbag; in this solution, the gas injected into the airbag can flow in the monitoring space and the water injection space, and the control button is triggered by controlling the flow of the gas to remind the staff to deal with the water pressure of the water supply pipe in time.

[0011] Preferably, the sealing component includes a sealing cover. The bottom of the sealing cover is fixedly connected with a threaded pipe. A thread adapted to the threaded pipe is arranged on the inner wall of the monitoring space and on the monitoring pipe. The threaded pipe is screwed into the monitoring pipe.

[0012] Preferably, the control button is installed at the central position of the inner bottom of the sealing cover, and the signal lamp and the timer are both installed at the outer bottom of the sealing cover.

[0013] Preferably, the pressure relief component includes an electric control valve, the electric control valve is connected to the timer through a circuit, the side wall of the monitoring pipe is connected to the inlet end of the electric control valve through a pressure relief pipe, and the outlet end of the electric control valve is externally connected to a water storage tank through a connecting pipe; in this solution, the timer can trigger the electric control valve to open and close the passage of the pressure relief pipe to achieve the pressure relief operation.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. The monitoring pipe is connected to the branch pipe through a flange. When it is necessary to clean the scale of the parts in the monitoring pipe, the water valve can be closed and the passage of the branch pipe can be closed, and then the monitoring pipe can be detached from the branch pipe for cleaning. While facilitating the cleaning of the internal parts of the monitoring pipe, it is not necessary to close the water supply in the water supply pipe, which is convenient for users to use water;

[0016] 2. A pressure relief component is arranged on the side wall of the monitoring pipe. When the control button is triggered, the timer is simultaneously triggered. When the water pressure in the water supply pipe has not been processed and the timer reaches the set value, the timer triggers the electric control valve to open the passage of the pressure relief pipe to drain the water in the monitoring pipe, so as to relieve the water pressure in the water supply pipe and avoid the water supply pipe from bursting due to excessive water pressure for a long time.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] Please refer to Figures 1-3 , the present utility model provides a technical solution: a water supply pipeline pressure monitor, including a water supply pipe 1, a branch pipe 2 arranged at the top of the side wall of the water supply pipe 1, a water valve 3 installed in the branch pipe 2, and the branch pipe 2 is connected to a monitoring pipe 5 through a flange 4. The top end of the monitoring pipe 5 is installed with a sealing component 6. A fixed partition 7 is fixedly connected to the inner wall of the monitoring pipe 5, an air bag 8 is installed on the fixed partition 7, a control button 14 is installed at the inner top of the sealing component 6, and a signal lamp 15 and a timer 16 are respectively installed on the outer top of the sealing component 6. The control button 14 is connected to the signal lamp 15 and the timer 16 respectively through a circuit. A pressure relief component 17 is connected to the side wall of the monitoring pipe 5, and the pressure relief component 17 is connected to the timer 16 through a circuit.

[0028] Specifically, the setting of the water valve 3 can control the on-off of the water flow in the branch pipe 2, so as to facilitate the disassembly of the monitoring pipe 5 from the branch pipe 2 and facilitate the cleaning of the scale attached to the components in the monitoring pipe 5.

[0029] The branch pipe 2 is vertically upwardly provided on the side wall of the water supply pipe 1. When the water pressure in the water supply pipe 1 increases, the water in the water supply pipe 1 enters the branch pipe 2 and the monitoring pipe 5 under the action of pressure. When the water flow accumulates to a certain volume, it will squeeze the airbag 8 and cause the airbag 8 to touch the control button 14, triggering the signal lamp 15 to remind the staff to deal with it in time and at the same time the timer 16 starts timing. When the staff fails to deal with it in time and the time reaches the set value, the pressure relief component 17 is triggered to discharge the water in the monitoring pipe 5 to reduce the water pressure in the water supply pipe 1.

[0030] Further, a through hole 10 is provided at the central position of the fixed partition 7. The airbag 8 is installed in the through hole 10, and a plug cover 9 is provided at the top of the airbag 8. The fixed partition 7 equally divides the accommodation space in the airbag 8.

[0031] Further, the fixed partition 7 divides the internal space of the monitoring pipe 5 from top to bottom into a monitoring space 13 and a water injection space 12. The molecular mass of the gas injected into the airbag 8 is greater than that of air, and the volume of the gas injected into the airbag 8 is 1 / 2 - 2 / 3 of the total volume of the airbag 8.

[0032] Specifically, a sealing ring 11 is installed at the bottom of the fixed partition 7 and in the water injection space 12 and on the peripheral side of the airbag 8; the accommodation space of the airbag 8 in the monitoring space 13 is the same as the accommodation space of the airbag 8 in the water injection space 12; in the initial state, the gas in the airbag 8 is stored in the water injection space 12. When the water flow in the monitoring pipe 5 is too much, it will squeeze the gas stored in the water injection space 12 in the airbag 8 into the monitoring space 13 until it touches the control button 14 and triggers the signal lamp 15 to remind the staff that the water pressure in the water supply pipe 1 reaches the critical value.

[0033] Further, the sealing component 6 includes a sealing cover 61. A threaded pipe 62 is fixedly connected to the bottom of the sealing cover 61. A thread adapted to the threaded pipe 62 is provided on the inner wall of the monitoring pipe 5 in the monitoring space 13, and the threaded pipe 62 is screwed into the monitoring pipe 5.

[0034] Specifically, the sealing cover 61 is installed on the monitoring pipe 5 through the threaded pipe 62, which is convenient for injecting or supplementing gas into the airbag 8.

[0035] Further, the control button 14 is installed at the central position of the inner bottom of the sealing cover 61, and the signal lamp 15 and the timer 16 are both installed at the outer bottom of the sealing cover 61.

[0036] Specifically, the signal lamp 15 is set so that when the water pressure in the water supply pipe 1 reaches the critical value, it can remind the staff to process the water pressure in time; the timer 16 is set so that when the staff cannot process the water pressure in time and reaches a certain time, it can trigger the pressure relief component 17 to discharge the water flow in the monitoring pipe 5 to achieve preliminary pressure relief.

[0037] Furthermore, the pressure relief component 17 includes an electric control valve 171. The electric control valve 171 is connected to the timer 16 through a circuit. The side wall of the monitoring pipe 5 is connected to the inlet end of the electric control valve 171 through a pressure relief pipe 172, and the outlet end of the electric control valve 171 is externally connected to a water storage tank through a connecting pipe 173.

[0038] Specifically, the pressure relief pipe 172 is communicated with the water injection space 12; when the pressure relief component 17 is triggered, the electric control valve 171 works to connect the pressure relief pipe 172 and the pressure relief pipe 172, and discharge the water in the water injection space 12 into the water storage tank to relieve the water pressure in the water supply pipe 1.

[0039] The working principle and usage process of the present utility model: After the present utility model is installed, when the water pressure in the water supply pipe 1 increases, the water in the water supply pipe 1 will move upward under the action of pressure into the branch pipe 2 and the monitoring pipe 5. When the water flow accumulates to a certain volume, it will pressurize the airbag 8, and gradually squeeze the gas in the airbag 8 from the water injection space 12 into the monitoring space 13. The airbag 8 in the monitoring space 13 will then squeeze the control button 14;

[0040] When the control button 14 is triggered, the signal lamp 15 works to remind the staff to process the water pressure in the water supply pipe 1 in time. At the same time, the timer 16 starts timing. When the time reaches the set value and the water pressure in the water supply pipe 1 has not been relieved, the timer 16 will trigger the electric control valve 171. The electric control valve 171 opens the channel of the pressure relief pipe 172, so that the water in the water injection space 12 is discharged into the water storage tank through the pressure relief pipe 172 and the connecting pipe 173 to reduce the water pressure in the water supply pipe 1 and avoid the water supply pipe 1 from bursting due to excessive water pressure for a long time.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
