Background

The pressure fluctuation in the pipe is caused by the drainage mechanism during drainage, the local vacuum is generated at the outlet of the trap, particularly, the negative pressure action is formed on the upper part of the vertical pipe for a short time when the flow of the drainage vertical pipe is large, so that the water seal is damaged, and the pressure requirement of the positive pressure cavity cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a malleation drainage mechanism, the trap who has solved the drain pipe produces the problem that the water seal leads to water drainage chamber pressure demand to guarantee in vacuum destruction water seal.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a malleation drainage mechanism, a serial communication port, it includes:

a conduit including an inlet and an outlet, at least one of said inlet and said outlet being lower than said inlet and outlet;

a feed portion in communication with the inlet;

a diffuser portion in communication with the outlet;

the feeding device comprises a feeding pipe, wherein one end of the feeding pipe is placed in the feeding portion, and a distance is set between the periphery of the feeding pipe and the feeding portion.

Further, the device also comprises a cylinder body, and the pipeline is arranged in the cylinder body.

Further, the bottom of barrel is provided with the bin outlet.

Further, the feeding portion is provided with a plurality of groups and communicated with the inlet.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

one position between the inlet and the outlet of the pipeline is lower than the inlet and the outlet, the pressure at the inlet and the outlet is balanced by utilizing the principle of the communicating vessel, and the water seal damage caused by vacuum is avoided.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the positive pressure drainage mechanism includes a pipe 1, a feed port 2, an expansion portion 3, a material pipe 4, a cylinder 5, a discharge port 6, an analysis meter 7, and a sample inlet 8.

Pipeline 1 is the U type and the position of import 11 is higher than the export, and feeding portion 2 is linked together with import 11, and feeding portion 2 is the diameter of column and diameter ratio pipeline 1 greatly, and import 11 can be provided with the multiunit, and feeding portion 2 can be provided with the multiunit simultaneously and import corresponding setting.

The expansion part 3 is connected with the outlet 12, and the diameter of the expansion part 3 is larger than that of the end of the outlet 12.

One end of the material pipe 4 is placed in the feeding part 2, the diameter of the feeding part 2 is larger than that of the material pipe 4, and a distance is set between the periphery of the material pipe 4 and the feeding part 2. The material pipe 4 is connected with an analysis meter 7 and is used for discharging a sample in the analysis meter 7. The sample inlet 8 is connected to the analysis instrument 7 for feeding the sample to the analysis instrument.

The pipe 1 is placed in the cylinder 5 to receive the sample discharged from the expansion portion 3, and then discharged from the discharge port 6 provided at the bottom of the cylinder 5.

The working principle of the positive pressure drainage mechanism is as follows:

1. fill with water in the dilatation portion 3 earlier, final liquid keeps balanced in U type intraductal both sides, and surplus liquid overflows to the barrel 5 in from dilatation portion 3, freely flows out through bin outlet 6.

2. When the pressure of the compressed air in the positive pressure cavity is increased, the water on the left side of the U-shaped pipe is reduced due to the increase of the air pressure, and redundant liquid overflows from the expansion part 3 to finally reach balance.

3. When the analyzer 7 starts to discharge water, the water level on the left side of the U-shaped pipe is increased, the pressure balance is broken, and the excess water flows out from the expansion part 3 to reach the balance again.

The function of the expansion part 3 is to replenish the water discharged by the wave motion in the U-shaped pipe.

The positive pressure drainer can be used as a safety measure for the discharge pressure of the explosion-proof positive pressure cavity, maintains the air pressure in the positive pressure cavity below 1000pa, and is used as a safety valve of the positive pressure cavity.
