Reference will now be made in detail to the present embodiments of the present invention, preferred embodiments of which are illustrated in the accompanying drawings, wherein the drawings are provided for the purpose of visually supplementing the description in the specification and so forth, and which are not intended to limit the scope of the invention.

In the description of the present invention, if there are first and second described only for the purpose of distinguishing technical features, it is not understood that relative importance is indicated or implied or that the number of indicated technical features or the precedence of the indicated technical features is implicitly indicated or implied.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

Referring to fig. 1, an embodiment of the present invention provides a leakage prevention protector, including: first casing 100, first current surveying module 200, second current surveying module 300, increase a class subassembly 400 and control module 500, can realize the water route leak protection, guarantee people's normal water, avoid water waste. The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 2 and 3, the first housing 100 is provided with a main channel 110 in a penetrating manner along a length direction, the first valve body 120 is arranged in the main channel 110, the main channel 110 is divided by the first valve body 120 to form a water inlet end 111 and a water outlet end 112, the first through hole 130 is arranged on the first housing 100 of the water inlet end 111, the second through hole 140 is arranged on the first housing 100 of the water outlet end 112, the first through hole 130 is communicated with the main channel 110, the second through hole 140 is communicated with the main channel 110, the main channel 110 is provided with a first flow measuring module 200, and the first flow measuring module 200 can detect a flow within a predetermined range, so that a flow test can be performed when water is normally supplied into the main channel 110.

Referring to fig. 2 and 3, the first housing 100 is a valve body housing, the main passage 110 is a waterway passage, and the first valve body 120 is driven to be turned on or off by the pressure of the fluid. When water is normally supplied, the fluid pressure drives the first valve 120 to open, so that water flows from the water inlet end 111 to the water outlet end 112, and when water leaks, the fluid pressure cannot drive the first valve 120 to open, so that water cannot flow through the water inlet end 111 to the water outlet end 112. It is easily understood that the first valve body 120 may employ a check valve. The one-way valve is provided with a conducting end and a stopping end, and the one-way valve is in one-way conduction in the direction from the conducting end to the stopping end, namely, water flow only can enter the one-way valve from the conducting end and flow out from the stopping end of the one-way valve, but cannot enter the one-way valve from the stopping end, so that the one-way valve plays a role in one-way conduction.

The check valve is used for preventing the fluid from flowing reversely. In this embodiment, the fluid can flow from the water inlet end to the water outlet end to prevent backflow, and the main channel 110 is divided to form two regions, so that the water can be prevented from flowing into the water outlet end 112 when water leaks. Specifically, one side of the water inlet end 111 of the main channel 110 is a water inlet, and one end of the water outlet end 112 of the main channel 110 is a water outlet.

The check valve can adopt a spring type check valve, liquid jacks up a valve clack controlled by a spring by virtue of pressure, and after the pressure disappears, the valve clack is pressed down by the spring force to seal the liquid to flow backwards. The check valve can also be a swing check valve, liquid flows in the first shell 100, the rotating valve clack on one side is pushed open by pressure, after the pressure is lost, the valve clack returns by self weight, and the valve clack is closed by reverse liquid pressure.

When water leaks, the flow rate of the fluid is outside the predetermined range of the first flow measuring module, the first flow measuring module 200 cannot detect the flow rate specific parameter, and the water flow is blocked by the first valve body 120. Therefore, the present embodiment specifically designs the second flow measuring module 300 on one side of the first casing 100. The second flow measuring module 300 includes a second housing 310 and a flow measuring unit 320. A cavity is formed inside the second housing 310, an input port 330 is arranged at the bottom end of the cavity, the input port 330 is communicated with the first through hole 130, an output port 340 is arranged at the bottom end of the cavity, the output port 340 is communicated with the second through hole 140, and a flow measuring unit for detecting flow is arranged in the cavity.

Referring to fig. 1, specifically, a base is disposed on an outer side of the first casing 100, the base is provided with two through holes communicating with the first through hole 130 and the second through hole 140, the second casing 310 is provided with two insertion pipes, the two insertion pipes respectively form an input port 330 and an output port 340, the two insertion pipes are inserted into the first through hole 130 and the second through hole 140, and the second casing 310 and the first casing 100 can be fixed by fasteners such as screws or bolts, which facilitates the detachment and installation of the second flow measuring module 300. In the event of a water leak, the water flow cannot drive the first valve body 120 to open, thereby entering the chamber through the input port 330. Therefore, in order to measure the flow rate of the water, a flow increasing assembly 400 is provided in the input port 330 or the first through hole 130.

Referring to fig. 4 and 5, the flow increasing assembly 400 is used to increase the fluid speed, and when the water flow is small, the water flow increases the speed through the flow increasing assembly 400, so that the flow measuring unit 320 located in the cavity can measure the water flow parameter when water leaks, and the system can recognize the water leakage state.
