The mixed liquid access pipe 11 is plugged with a mixed plug 2 at the position of the orifice.

As shown in fig. 2 and 3, the mixing plug 2 includes a casing 21 having a frustum shape as a whole and a flange 25 provided at a large end of the casing 21. The frustum-shaped housing 21 allows the mixing plug 2 to be smoothly inserted into the nozzle of the mixed liquid inlet pipe 11. The outer diameter of the large end of the mixing plug 2 is 0.8mm larger than the inner diameter of the orifice of the mixing liquid inlet tube 11 to prevent the large end of the housing 21 from completely entering the orifice of the mixing liquid inlet tube 11. When the housing 21 is inserted into the nozzle of the mixing fluid inlet tube 11, there is a gap between the flange 25 and the nozzle, and during the disassembly process, the operator can apply a force on the flange 25 near the sidewall of the nozzle to facilitate the removal of the mixing plug 2.

The spiral flow deflector 32 increases the moving distance of gas and water vapor, and because water vapor and gas move upwards under the natural state, the flow deflector 32 shields the original path of the masonry and the water vapor, the water vapor can only move along the flow deflector 32 in the gas, and the lower surface of the flow deflector 32 is in contact with the gas and the water vapor. The steam is cooled and condensed into water drops after contacting with the flow deflector 32, the water drops with smaller volume move along the lower surface of the flow deflector 32, and after a plurality of water drops are gathered to form larger water drops, the water drops on the upper surface of the flow deflector 32 under the action of gravity and flows along the upper surface of the flow deflector 32, and finally the water drops return to the body 1. Compared with the prior art, the setting of water conservancy diversion stopper 3 has reduced the steam content that gas was taken away from body 1, reduces the content of the vapor that gets into check out test set promptly, will help reducing fluorescence quenching effect to reduce the loss of measurement signal, with this improvement experimental accuracy.

In this embodiment, the mixing plug 2 and the flow guiding plug 3 are made of silicon rubber, and are made of the same material as the hose for conveying liquid, so that the influence of the material of the mixing plug 2 and the flow guiding plug 3 on the experimental result is reduced.

Example 2:

the present embodiment is different from embodiment 1 in that, as shown in fig. 4, the mixing plug 2 includes a housing 21 having a frustum shape as a whole, and a plurality of grid pieces 24 are disposed on an inner wall of the housing 21, and each of the plurality of grid pieces 24 is disposed perpendicular to an axis of the housing 21. In the present exemplary embodiment, two grating segments 24 are provided.

The liquid that gets into behind the mixed stopper 2 is shunted by grid piece 24, and the meeting mixes once more after leaving grid piece 24, makes liquid meet and shunt many times because of setting up of a plurality of grid pieces 24 for liquid mixes comparatively fully, improves the effect of experiment. And the mixing plug 2 is simple in structure and easy to manufacture.

Example 3:

the difference between this embodiment and other embodiments is that, as shown in fig. 7 and 8, the flow guide plug 3 includes a tubular pipe body 31, the pipe body 31 is plugged at the pipe orifice of the gas discharge pipe 13, the inner wall of the pipe body 31 is provided with a plurality of flow guide plates 33, in this embodiment, the flow guide plates 33 are arranged in a semicircular plate shape, and the number of flow guide plates 33 is four.
