Detailed Description

Example 1

As shown in fig. 1 to 4, the auxiliary measuring device for the sewage quantity of the flowmeter comprises a separation box 2, wherein an input end 27 and an output end 28 of the separation box 2 are respectively connected with a control valve 3; the control valve 3 is a pneumatic valve.

The upper end of the separation box 2 is connected with an exhaust valve 1;

a liquid level meter I21 is arranged on the inner side wall of the separation box 2 below the exhaust valve 1;

space I25 and space II 26 are respectively arranged on two sides of the interior of the separation box 2, and the space I25 is communicated with the space II 26;

the input end 27 and the output end 28 of the separation box 2 are respectively and correspondingly positioned below the space I25 and the space II 26;

a filter mechanism 5 is arranged in the upper space II 26 corresponding to the output end 28;

a liquid level meter II 22 is arranged on the inner side wall of the separation box 2 above the filtering mechanism 5.

The filter mechanism 5 comprises a plurality of layers of filter cotton 52 which are arranged, and a positioning plate 51 is arranged between the filter cotton 52;

the positioning plate 51 is mounted on the inner side wall of the separation tank 2 in the space ii 26.

The inside baffle 29 that upwards extends that is equipped with of separator box 2, baffle 29 top is less than the level gauge at least 100mm, if set up too little, when the water yield is big, causes the mistake easily to touch to influence the use.

The level gauge II 22 is at least 100mm higher than the filtering mechanism 5, avoiding the gas inside the separation tank 2 from contacting the filter cotton 52.

The detachable mounting plate 23 is arranged outside the separation box 2, the position of the mounting plate 23 corresponds to the position of the filter mechanism 5, and the mounting plate 23 is used for replacing the filter cotton 52.
