Description

Float hydrolock floor drain

One, technical field

The utility model relates to a kind of novel float hydrolock floor drain.

Two, background technology

In the building in modern times, pipeline is an indispensable key factor for the mankind's life, feedwater, blowdown, series of activities such as ventilation make all has staggered pipeline in length and breadth to connect in each solitary building, but owing to pipeline often is placed among the reinforced concrete, so people have ignored the problem of pipe safety greatly.

2003, Amoy Garden, Hong Kong became the synonym of SARS, and in short several time-of-weeks, a building high-rise apartment building has 321 people's cross-infection SARS virus unexpectedly, had brought the huge injury that imprints on the bones and the memory for a lot of families! The World Health Organization and the expert of Department of Health of the Hong Kong Special Administrative Region spell out in survey report behind probe: the reason that the Amoy Garden epidemic situation spreads fast is exactly because the floor drain in room has been lost the function that intercepts from harmful germ in the blow-off line.

The drainage system in room is: though resident family of every family is independently on building structure, from drainage pipe-septic tank-floor drain drainage system, then be interconnected between each resident family.By " floor drain " this " reversible safe door " huge numbers of families' obstruct is come, floor drain is as the important channel that is connecting ground, room and sewer pipe, bearing the important task of the daily life sewage of draining the daily use generation of resident on the one hand, then need on the other hand to finish and stop that various hazardous substancess pass to indoor requirement by floor drain, in case " safety door " goes wrong, the room will directly be communicated with drainage system, exist huge hidden danger! Be interconnected between the drainage pipe-septic tank of resident family of every family, but the hydrolock floor drain is easy to cause room and drainage system directly to be communicated with because of the fluctuation of water evaporates or pipeline internal gas pressure causes water seal destroyed, exists huge hidden danger! Does why traditional floor drain have no idea to finish the important function of " safety door "? the floor drain that uses in the family is generally the hydrolock floor drain of hopper structure in the market.Although the hydrolock floor drain is rational in infrastructure, use simple.But because this kind floor drain is to rely on water to realize sealing, there is fatal drawback, the one, because the defective of floor drain design itself, only can deposit very a spot of water in the seal groove, these limited water electrodes are volatile, in case dry, the floor drain sealing was lost efficacy immediately, thereby forfeiture intercepts the function from the pernicious gas in the blow-off line.Analyze the process of the SARS virus propagation of Amoy Garden: disease patient's excreta enters in the septic tank by pipeline, decomposing the germ that comes out spreads in sewer pipe wantonly, because the kitchen of many resident families, washroom floor drain aqua storage tank is dry, causes its " water-stop " to lose efficacy, like this, germ is by losing the floor drain of obstructing capacity, enter inside, room easily, infect apace and give the people, thereby caused serious consequence.Therefore, is the improvement of floor drain imperative with innovation?

Three, utility model content

At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just is to provide a kind of novel float hydrolock floor drain, can effectively solve existing floor drain causes water seal destroyed because of water evaporates or the fluctuation of pipeline internal gas pressure, forfeiture intercepts the function from the pernicious gas in the blow-off line, the problem that has potential safety hazard, the technical scheme of its solution is, the utility model comprises drain cover, floor drain body and sewer pipe, drain cover is arranged at floor drain body top, and the sewer pipe that communicates with drainage pipe is arranged at the floor drain body bottom, is equipped with float on the delivery port of tank in the bottom of floor drain body, balance handle is equipped with in the float bottom, balance handle stretches in the sewer pipe, and the utility model floor drain simplicity of design is drawn materials conveniently, overcome " fatal " shortcoming of traditional floor drain anhydrous then " gas leakage ", economic and social benefit is remarkable.

Four, description of drawings

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is a sectional drawing of the present utility model.

Fig. 3 is Floater Structure figure of the present utility model (amplification).

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done detailed explanation.

As Fig. 1-shown in Figure 2, the utility model comprises drain cover, floor drain body and sewer pipe, drain cover 1 is arranged at floor drain body 2 tops, the sewer pipe 3 that communicates with drainage pipe is arranged at the floor drain body bottom, be equipped with float 4 in the bottom of floor drain body on the delivery port of tank 6, balance handle 5 is equipped with in the float bottom, and balance handle stretches in the sewer pipe.

In order to guarantee result of use, delivery port (suitable for reading) diameter on said sewer pipe top is identical with the diameter of float, float place sewer pipe suitable for reading in, said float is the ball sealer (weight that is float less than buoyancy of water, water can float ball float) of density less than water.

If the diameter at sewer pipe place suitable for reading is slightly littler than the diameter of ball sealer (float), float can not float, because float one leaves water pipe slightly, flowing liquid pressure reduces, and float has been pressed again and gone back, and so repeatedly, water velocity is very slow.When the diameter of water pipe is about three of float diameter/for the moment, under the effect of solid stream of water, the phenomenon----that " dancing " appearred in float is significantly sunk and is floated, and presents a kind of dynamic equilibrium.Continue to reduce flowing water mouth diameter (replacing water pipe with sheet metal and nut in the experiment), can see that float is floating at the water surface, water flows away from water pipe.

Working condition of the present utility model is, 1, when water level in the tank is higher than the sewer pipe mouth, and ball sealer (float) come-up, water is drained from sewer pipe;

2, when water level in the tank is lower than the sewer pipe mouth, ball sealer (float) falls, and the sewer pipe mouth is sealed.Water in the tank also plays sealing function simultaneously.Realize float envelope and water seal dual fail-safe.

If 3 because evaporation makes the water in the tank withered phenomenon occur, then ball sealer (float) will play sealing function separately.Overcome the anhydrous then drawback of gas leakage of daily life floor drain.

4, be in all the time above the mouth of pipe because of the balance handle on the ball can guarantee ball, make ball not break away from the mouth of pipe, so further guaranteed the reliability of sealing.

5, such design can also reduce the degree of depth of floor drain, reduces maximum moisture storage capacity, avoids the long-time existence of water in the floor drain to grow germ.

The utility model floor drain simplicity of design is drawn materials conveniently, attention to hygiene, and prevent disease all can play " safety door " effect having under water and the anhydrous situation, overcome " fatal " shortcoming of traditional floor drain anhydrous then " gas leakage ", and economic and social benefit is remarkable.
