Abstract

The utility model relates to a blast-proof toxicity-proof floor drain used in the civil air defense, comprising a handle, an upper cover plate, a lower cover plate and a floor drain body. The upper cover plate is matched with the upper port of the floor drain body through a thread buckle, the lower cover plate is connected with a sealing pad to be closely matched with the outlet of the floor drain body, and the connecting part between the upper and the lower cover plates are in the concave and convex shape. The upper cover plate of the utility model can freely rotate, and the lower cover plate can only move vertically. The utility model has long service life and reliable sealing performance, can be completely used in the civil air defense in five grade or six grade, or be used in the civil air defense with a higher grade or in the underground space with higher decoration grade.

Description

Blast-proof toxicity-proof floor drain

The utility model relates to a kind of floor drain, especially the Blast-proof toxicity-proof floor drain of civil air defense constructions and installations aspect.

In the prior art, a kind of " double-layer seal anti-overflow valve " disclosed in CN2063543, its objective is and prevent the excessive of sewage, foul smell, its formation is to return water tumbler and sealed valve cap, also having an external diameter is pyramid type on top, is columniform influent hopper in the bottom, and fixedly ining succession one on the external diameter in the middle part of the cylindrical pipeline section of influent hopper has the Drinking cup lid that returns in water hole, return to be connected with on the Drinking cup lid and return water tumbler, the close valve pocket of annular is contained in the upper end of returning Drinking cup lid on the influent hopper; " a kind of floor drain that the anti-overflow ball valve is housed " disclosed in CN209387171, its objective is that smelly, the anti-foreign material that prevent to overflow enter in the pipe, its structure is the ground fistulae that has water sealed tank, its water sealed tank is stamped deodorant cover, the double-edged fine-toothed comb that leaks is equipped with at the top of water sealed tank, it is step to be arranged and in the inside pipe wall appropriate location the real thing that rises is arranged that ground gushes pipe, and the anti-overflow ball valve of being made up of valve seat and valve ball is housed on the step of pipe.By the above as seen, present floor drain is used for playing the purpose of deodorization, anti-overflow in the daily civil engineering more.Though speciality store is useful on the floor drain in the people's air defense, its upper and lower cover plate is a monolithic, sealing mat with cover plate rotate, yielding, influence sealing reliability and application life.

The purpose of this utility model is to overcome above-mentioned deficiency, and the life-span length of using in a kind of civil air defense constructions and installations, the floor drain of dependable performance are provided.

The utility model can be realized like this: Blast-proof toxicity-proof floor drain, comprise handle, upper cover plate, lower cover, leakage body, upper cover plate with leak body and cooperate for screw thread between suitable for reading, lower cover connects sealing mat can export driving fit with the leakage body, cooperate at the junction concave-convex surface between the upper and lower cover plate, and locate by screw.The utility model can be used on the civil air defense constructions and installations of horizontal line combination.Upper cover plate is free to rotate, and lower cover is connected with sealing mat, because upper cover plate is suitable for reading for screw thread cooperates with the leakage body, the rotation upper cover plate can make lower cover vertically move, and makes sealing mat and leaks body outlet driving fit, promptly can reach the purpose of close fit, sealing.

Convex place at described convex cover plate can have annular groove, screw is set inserts in this groove.Can connect upper and lower cover plate like this, when making the upper cover plate rotation, lower cover still only vertically moves and can not follow upper cover plate and rotate, make sealing mat to avoid wearing and tearing, protects the reliability that is just sealing.

Reinforce at described leakage body available stainless steel coil suitable for reading, can when improving bulk strength, increase attractive in appearance again.

Fig. 1 is the utility model structural representation

Further specify the utility model below in conjunction with accompanying drawing:

The A position is use location at ordinary times, ground leak opening;

The B position is the use location in wartime, prevents overflowing of shock wave and poison gas, is in closed condition;

Blast-proof toxicity-proof floor drain, comprise handle (1), upper cover plate (2), lower cover (3), leakage body (4), upper cover plate (2) and leak between the body (42) suitable for reading and cooperate for screw thread, lower cover (3) connects grease proofing acid-proof sealing mat (5) can export (41) driving fit with the leakage body, upper cover plate (2) and lower cover (3) junction concave-convex surface are connected, be that upper cover plate (2) is a concavity, lower cover (3) is a convex, or upper cover plate (2) is a convex, lower cover (3) is a concavity, is located by the fixing distance between cover plate up and down of screw (7).When need are closed floor drain, only need the handle (1) on the turn upper cover plate (2), lower cover this moment (3) is vertically motion only, makes sealing mat (5) tightly push down the purpose that Lou body outlet (41) reaches close fit, sealing.The convex place of the described convex cover plate in upper and lower cover plate junction can have annular groove (6), screw (7) is set inserts in the groove (6), in order to guarantee the relative position between the upper and lower cover plate, makes the rotation of upper cover plate more flexible, and lower cover moves more freely.

The utility model leaks body available stainless steel coil suitable for reading to be reinforced, and has improved impact resistance and application life, has increased attractive in appearance again.

The flat war of the utility model is dual-purpose, and conversion is convenient, locates the A position at ordinary times, locates the B position wartime.For the utility model of ∮ 80, static pressure test is 1.2MPa, is applicable to the anti-contaminated area and the clear area of 5 grades, 6 grades civil air defense constructions and installations fully, also can be used for more

The high level civil air defense constructions and installations or the higher underground space of decoration class.
