Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this water leakage detection mechanism includes the shell 1, big that two sides are respectively provided with water inlet 11 and water outlet 12
Flow detector 2, small flow detector 3, check valve 4 and the opening and closing valve 9 being connected at water outlet 12.
Wherein, the top of shell 1 has recessed and cylindrical installation cavity 1 and installation cavity 2 14, installation cavity one
13 and installation cavity 2 14 be set side by side and separated between the two by lattice 15.The bottom of installation cavity 1 and shell 1
Water inlet 11 be connected and check valve 4 is fixed in installation cavity 1, the bottom of installation cavity 2 14 and the water outlet 12 of shell 1
It is connected and big flow detector 2 is fixed in installation cavity 2 14, lattice 15 offers at top can be connected to installation cavity
1 and installation cavity 2 14 cross the mouth of a river 16.The opening difference at 2 14 top of one 13 top open part of installation cavity and installation cavity is close
Envelope is connected with closeouts 1 and closeouts 26, and the bottom of shell 1 offers micro- leakage channel 17, and small flow detector 3 is set to
At micro- leakage channel 17.In the present embodiment, common flowmeter or Hall sensor and impeller can be used in big flow detector 2
Combination；Existing common check valve 4 or check-valves can be used in check valve 4；It opens and closes valve 9 and uses ball valve or solenoid valve；Envelope
Blocking piece 1 and closeouts 26 are threadedly coupled with shell 1.
Specifically, micro- leakage channel 17 includes opening up the straight hole and position that direction opens up along water inlet 11 and water outlet 12
In the recessed cylindrical test chamber 18 in 1 bottom of shell, test chamber 18 is located at the middle part of straight hole and small flow detector 3 is set to
At test chamber 18, the opening of test chamber 18 is sealedly connected with capping 7.In the present embodiment, small flow detector 3 includes setting
In impeller, the magnet that is connected on impeller and the Hall sensor being set to outside test chamber 18 in test chamber 18.
The water inlet end in micro- leakage channel 17, i.e., be connected with cylindrical fender 8, the fender 8 at the water inlet end of straight hole
Towards water inlet 11, the erosion control that water inlet 11 is connected with micro- leakage channel 17 can be led to by offering in fender 8 for the end of one end
Road 81, and the inlet in erosion control channel 81 is located at the side of fender 8.
The mountable total water outlet in pipeline of this water leakage detection mechanism, detects pipe leakage in the case where user's unused water
Situation, if pipeline occurs biggish damaged and water is caused largely to leak out, the two sides of check valve 4 will appear biggish hydraulic pressure
Difference, check valve 4 are opened, and water flow passes through installation cavity 1 from water inlet 11, crosses the mouth of a river 16, installation cavity 2 14 and the stream of water outlet 12
Out, simultaneously, water flow can also flow into micro- leakage channel 17 from the erosion control channel 81 in fender 8, and flow from water outlet 12
