[0021] Step 3: When the collecting device is far away, pull the fixed plate, and the bellows will be extended and lengthened, so that the filter cylinder at one end of the drainage hose can be placed in the collecting device. After use, push the bellows into the storage box, and at the same time, the plug post at one end of the fixed plate enters the groove at one end of the storage box. The storage box stores the contracted bellows. The length of the drainage hose can be adjusted by setting an extension component to avoid the filter cylinder being unable to be placed in the collecting device to collect water when the collecting device is far away. When the plug post enters the groove, the magnetic block 1 at one end of the plug post can be adsorbed with the magnetic block 2 in the groove to achieve the effect of adsorbing and fixing the fixed plate. At the same time, an arc-shaped edge is set at one end of the storage box, and a rubber pad is set on the arc-shaped edge to avoid wear of the side of the inner end of the storage box on the bellows.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention installs the arc plate to the lower end of the tee pipe through the mounting plate and the mounting bolts by setting a support assembly. When the device is in use, the suction cup at the lower end of the support column adsorbs the table surface, thereby achieving the effect of supporting and fixing the device. By setting the support assembly, the device can be supported and fixed when it is used, avoiding the device being placed randomly, which may cause the first control valve and the pressure gauge to be easily damaged by collision.

[0024] 2. The present invention sets a connecting component. When the filter screen cylinder is installed, the pull plate is pulled to drive the slide rod and the limit plate to slide in the fixed cylinder, and the spring is compressed. Then the filter screen cylinder is placed on the lower end of the connecting cover, and the plug plates on both sides of the upper end of the filter screen cylinder are inserted into the slots at the lower end of the connecting cover. The pull plate is released, and the spring is extended to push one end of the slide rod into the clamping hole of the plug plate, thereby achieving the effect of limiting and fixing the plug plate and the filter screen cylinder. The connection component is set to facilitate the quick disassembly, assembly and fixation of the filter screen cylinder.

[0025] 3. The present invention provides an extension component. When the collecting device is far away, the fixing plate is pulled, and the bellows is extended and lengthened, so that the filter screen cylinder at one end of the drainage hose can be placed in the collecting device. After use, the bellows is pushed into the storage box. At the same time, the plug post at one end of the fixing plate enters the groove at one end of the storage box. The storage box stores the contracted bellows. The extension component can be used to adjust the length of the drainage hose to avoid the filter screen cylinder being unable to be placed in the collecting device to collect water when the collecting device is far away.

At this time, the pressure gauge 10 can detect the water pressure during flow. At the same time, the flow meter 9 can detect the flow rate of water. After the detection, the filter screen cylinder 4 can be removed to observe whether there are impurities inside, so as to determine whether the water transported by the pipeline has impurities.

[0058] Working principle and use process of the present invention: When the pressure flow detection device of the household tap water network is used, the device is installed at a suitable position, and the water inlet hose 13 is connected to the pipeline detection point through the threaded connecting pipe 14. When it is necessary to detect the static water pressure, the first control valve 8 is closed and the second control valve 12 is opened. At this time, water is transported to the pressure measuring tube 11 through the water inlet hose 13, the three-way pipe 1 and the second control valve 12. The pressure gauge 10 on the pressure measuring tube 11 detects the static water pressure. When it is necessary to detect the flowing water pressure, the first control valve 8 and the second control valve 12 are fully opened, and water flows through the water inlet hose 13, the three-way pipe 1, the flow meter 9, the first control valve 8 and the drainage hose 6. The water flows through the drain hose 6 to the collection device. At this time, the pressure gauge 10 can detect the water pressure during the flow. At the same time, the flow meter 9 can detect the flow of water. After the detection, the filter screen cylinder 4 can be removed to observe whether there are impurities inside, so as to judge whether the water transported by the pipeline has impurities.
