Description

Box type double-layer water seal

Technical Field

The utility model relates to a sealed facility especially relates to a box double-deck water seal.

Background

Air conditioning unit can produce the comdenstion water on its surface cooler when work, and air conditioning unit new trend entry can have rain/snow water to get into in precipitation weather simultaneously, and the comdenstion water and rain/snow water collect the back through dedicated water-collecting tray, and the rethread drain pipe is arranged in the sewer. The amount of condensed water or rain/snow water which is poured into the fresh air inlet is not large, so that the water does not fill the whole drain pipe but flows along one side of the inner wall of the drain pipe during drainage.

In order to prevent the foul gas in the sewer from entering the room along the drain pipe, a trap needs to be arranged at the tail end of the drain pipe, and when water is drained, water accumulated in the trap can form a water seal to prevent the foul gas in the sewer from upwelling.

However, water in the trap of the drain pipe communicated with the indoor space is completely from condensed water, and if the water is not supplemented by the condensed water, a small amount of water accumulated in the trap is quickly dried, so that dirty air in the sewer is introduced into the indoor space. In actual use, the air conditioner in summer can blow off unpleasant odor for the first time after long-term non-operation, and the warm air blown by the air conditioner in winter always has unpleasant odor because of the dryness of the trap and not because of the dirt of the filter screen of the air conditioner (in fact, the air conditioner without the filter screen can also have the above two problems).

In addition, the terminal host computer of total air system central air conditioning leads to the air pressure difference of its front and back functional section because the influence of inside fan position, therefore the pressure that is located the drain pipe of different functional sections also is different, when carrying out the drainage, often receives a lot of drain pipes that the pressure is different behind respective trap and carries out the drainage. The two problems are caused, one is that after the pipeline with positive pressure and the pipeline with negative pressure are connected together, different functional sections are communicated, back mixing is formed to a certain extent, and the normal work of the air conditioner is influenced; the second is that after the pipeline with the positive pressure is received together with the pipeline of negative pressure, the trap both sides are positive pressure and negative pressure respectively, lead to the water in the trap to be discharged under the synergistic effect, and the water seal effect loses. In practical use, the air conditioner sometimes sends out bubbling sound from the condensate pipe in summer, namely, because of the bubbling sound.

In addition, in some areas, due to municipal administration problems, the situation that residents pour kitchen waste into the sewer occurs, organic matters in the sewer are fermented to generate a large amount of gas, the sewer has certain pressure, the trap is difficult to work normally, and more dirty gas in the sewer enters a room (namely 'reverse gas').

SUMMERY OF THE UTILITY MODEL

The utility model provides a box-type double-layer water seal.

The technical problem to be solved is that: the existing air conditioner drain pipe adopts a trap to seal water, water in the trap is easy to dry, and the trap can be damaged by pressure in a multi-connected central air conditioner to lose efficacy, and is easy to lose efficacy on a sewer with pressure.

In order to solve the technical problem, the utility model adopts the following technical scheme: a box-type double-layer water seal is used for draining water to a sewer with frequent reverse air; the device comprises a buffer container arranged at the lower end of a drain pipe, wherein a water seal overflow device for draining water is arranged in the buffer container;

the lower ends of the drain pipes are inserted under the liquid level of the buffer container together.

Further, water seal overflow arrangement includes the overflow pipe and the opening of intercommunication with the sewer and set up the water seal cover in buffer container downwards, the overflow pipe is vertical upwards to penetrate buffer container and insert the water seal cover, leaves the clearance that supplies water to flow out between water seal cover inner wall and the overflow pipe.

Further, a connecting rod for preventing the upper end of the overflow pipe from shaking is fixed in the water seal cover through an anchor, and the connecting rod is vertically inserted into the overflow pipe downwards and is fixedly connected with the overflow pipe.

Further, a grid plate is horizontally anchored at the overflow pipe opening, and the connecting rod penetrates through the grid plate downward and is locked by a bolt.

Further, the buffer container is a sealed container.

Furthermore, the buffer container is an iron bucket with a movable cover plate sealed at an opening, and the water sealing cover is anchored below the movable cover plate.

Furthermore, one end of the overflow pipe, which is positioned outside the buffer container, is inserted into a steel pipe with a flange plate at the lower end, the upper end of the steel pipe is in full-welding connection with the bottom of the iron bucket, and a gap between the overflow pipe and the steel pipe is sealed by a sealing ring.

The utility model relates to a box double-deck water seal compares with prior art, has following beneficial effect:

in the utility model, by arranging the buffer container with large capacity, water used for the water seal overflow device is not easy to dry, and the drain pipes with different pressures are not directly communicated, so that the formation of back mixing is avoided to influence the normal work of the air conditioner, and compared with a trap, the water in the buffer container can not influence the water seal effect even if flowing due to the pressure change of the drain pipes;

the utility model discloses in, be provided with the water seal cover on the overflow pipe, not only reduced the area of contact of the water in the dirty gas in the sewer and the buffer container, avoided the water in the buffer container smelly because of the dirty gas in the long-time contact sewer, moreover on the basis of inserting the drain pipe under the liquid level, additionally increased the one deck water seal, no matter like this in the sewer gas refluxes or the drain pipe pressure risees suddenly, all can have at least one deck water seal effective.
