Problems solved by technology

[0005] In view of the above analysis, the present invention aims to provide a fault alarm check drainage system and a check drainage method to solve the problem that the existing gravity drainage system is used in basement drainage, which cannot prevent backfilling and the check valve is easily stuck by impurities. The system cannot be reset in time, and false alarms are reported, which leads to the failure of the system

Embodiment 1

[0070] A specific embodiment of the present invention discloses a drainage check system, such as Figure 24 to Figure 28 As shown, including check valve 101, check valve outer tube 5 and outer tube cover 6; wherein, check valve 101 is located in check valve outer tube 5, check valve outer tube 5 is divided into upstream cavity and For the downstream cavity, the check valve 101 can be opened under the impact of upstream water flow or controlled by external force, so that the upstream cavity can communicate with the downstream cavity, and the check valve 101 can be closed under the control of its own gravity or external force, so that the upstream cavity can communicate with the downstream cavity. The downstream cavity is sealed and separated; the outer tube cover 6 is detachably arranged on the outer tube 5 of the check valve, and the outer tube cover 6 is opened for maintenance or replacement of the check valve 101 .

[0071] In this example, if Figure 1 to Figure 3 As shown...

Embodiment 2

[0109] Considering that only one check valve 101 is installed in the drainage check system, once the check valve 101 fails, if the rear end of the check valve 101 is blocked by foreign matter, the drainage check system cannot work normally, and it is difficult to maintain when the drainage volume is large. The working stability of the drainage check system is poor.

[0110] Based on the above problems, another specific embodiment of the present invention discloses a double check drainage system on the basis of the common drainage check system in Embodiment 1, such as Figure 29 As shown, including the check valve outer tube 5 and the outer tube cover 6, at least two check valves 101 of embodiment 1 are arranged in the check valve outer tube 5, and the check valve 101 can be controlled by the impact of upstream water flow or external force. Open, and the check valve 101 can be closed under the control of its own gravity or external force. Among them, the check valve 101 is a pur...

Embodiment 3

[0121] Due to the relatively single function of the existing drainage check valve products, it only plays the role of preventing backflow in the pipeline, and does not have the ability to discharge backwater downstream. Another specific embodiment of the present invention discloses a downstream pipeline backwater alarm non-return drainage system, such as Figure 30 to Figure 31 As shown, the system includes the check valve 101 of Embodiment 1, the outer tube 5 of the check valve and the outer tube cover 6 , and the check valve 101 is a purely mechanical check valve or an electric check valve. Among them, the pure mechanical check valve relies on the impact of drainage and the gravity of the check valve to open and close; the electric check valve relies on the control motor to open and close.

[0122] In this embodiment, the check valve outer pipe 5 is used to install components such as the check valve 101 , the submersible sewage pump 9 , and the sensor (liquid level gauge). ...

Abstract

The invention relates to a fault alarm check drainage system and a check drainage method, belonging to the technical field of building water supply and drainage, and solves the problem that the existing gravity drainage system is applied to basement drainage and cannot prevent backflow. The fault alarm check drainage system includes a check valve, an outer pipe of the check valve, a fault monitor, a monitoring component and a control system; the monitoring component is used to monitor the water level state in the outer pipe of the check valve; the control system includes a controller and an alarm device; The controller is connected with the monitoring component and the fault monitor, the controller is used to receive the water level signal monitored by the monitoring component and the information on whether the check valve is faulty detected by the fault monitor, and can judge whether the check valve is faulty, according to the Whether the check valve is faulty or not, the check valve and the alarm device will be sent an action command. The invention can be applied to the drainage of basements, solves the problem of failure of the drainage system caused by false alarm of the check valve due to malfunction, and improves the reliability of the drainage system.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage, in particular to a fault alarm non-return drainage system and a non-return drainage method. Background technique [0002] According to the "Building Water Supply and Drainage Design Standard" GB50015-2019, when the indoor ground of a building is lower than the outdoor ground, a sewage sump, sewage pump or finished sewage lifting device should be installed. [0003] For the drainage system with sewage sump and sewage pump, the sump should have a certain volume to meet the water output of the drainage pump for at least 5 minutes. It should also meet the installation and inspection requirements for water pump settings, water level controllers, and grilles. Set the flushing pipe at the bottom and configure the super-warning water level alarm device. From the above design requirements, it can be known that the use of sump and sewage pump as basement drainage will inevitably...
