Description

The energy storage type floor drain

Technical field

The utility model relates to a kind of mechanical dewatering installation, and this device can be discharged in the sewer ponding on ground, and can prevent that the foul smell that gathers in the sewer from overflowing.This device generally is used for the draining of building, is commonly called as floor drain.

Background technology

Floor drain is the building dewatering installation that generally uses, and generally is installed on the flooring in the building and the outfall place on ground, and excess surface water enters drainage pipe by floor drain, and floor drain mainly plays draining and prevents that the foul smell that gathers in the drainage pipe from overflowing.For the foul smell that prevents to gather in the drainage pipe overflows, present known floor drain mainly contains two kinds of seal form:

The one, the water seal form.Typical water seal form floor drain is made up of ring-like water storage flume and back-off bowl seal lid, and excess surface water enters sewer by the gap of annular water tank and seal cover, utilizes water residual in the water storage flume to realize sealing, prevents that the foul smell in the sewer from overflowing.This form structure is simple, but main problem, the one, impeded drainage; The 2nd, residual water does not have a sealing function once dried, and foul smell up turns over easily; The 3rd, can not prevent that smelly water from pouring in down a chimney; The 4th, can not prevent that toy from climbing into.

The 2nd, the forced action type sealing.Typical forced action type sealing device employing elastic body is formed a draining valve that opens and closes automatically with valve body and obstruction, elastic body and obstruction interlock.When not having flowing water, utilize the effect of elastic force, make to stop up closely to contact the realization sealing with valve body drainage channel port; When flowing water, the action of gravity of the water that is flowed in the valve body is offset elastic force and is made obstruction open the realization draining in obstruction.This form usually because the performance of elastic body is inconsistent, stop up the deviation of shift position or the influence of streamflow regime, causes the opening instability, causes poor sealing and impeded drainage.

Summary of the invention

The purpose of this utility model provides a kind of forced action type seal floor drain that adopts the accumulation chamber structure, has solved the opening problem of unstable, has realized the unobstructed and good sealing of draining, and can prevent that backing up of sewage and toy from climbing into.

The technical scheme that the utility model adopted is in the known forced action type seal floor drain structure of being made up of elastic body, valve body and plug members that opens and closes automatically, to increase the accumulation chamber that a bottom has discharge orifice.Fig. 1 is a structural representation of the present utility model, comprises upper cap nut (1), spring (2), deflector (3), valve body (4), accumulation chamber (5), axle (6), stops up (7) and following nut (8).Spring (2) is inserted in axle (6) top, places between upper cap nut (1) and the deflector (3), and upper cap nut (1), spring (2), deflector (3) are formed elastic body with axle (6) upper end.Following nut (8) will stop up the lower end that (7) are fixed in axle (6), stop up (7), following nut (8) and axle (6) lower end and form plug members.The flexible of elastic body medi-spring (2) is transferred to axle (6) top by upper cap nut (1), and the middle part drive plug members by axle (6) moves up and down again.The link gear of elastic body and plug members is formed at elastic body, plug members and axle (6) middle part, has born the function of drive disk assembly at this mechanism's axis (6) middle part.Accumulation chamber (5) places on the shaft shoulder of axle (6), and accumulation chamber (5) can drive obstruction (7) and move when moving down.Accumulation chamber (5) bottom has discharge orifice.The size of discharge orifice, the discharge in the time of should making displacement by discharge orifice much smaller than the normal draining of floor drain; The position of discharge orifice to be being positioned at accumulation chamber bottom for well, so that floor drain is when stopping draining, sludgd deposition is avoided in the accumulation chamber emptying of can trying one's best, thereby and reduce the sealing load of accumulation chamber weight increase floor drain, but its position is insensitive to the influence of this floor drain function.When explaining this structure, regard axle (6) combination of top, middle part, three parts in bottom as, its middle and upper part is the ingredient of elastic body, and the bottom is the ingredient of plug members, and the middle part is a drive disk assembly.In the practical application, other rigid structures can be developed in axle (6) middle part, for example with accumulation chamber itself as drive disk assembly, the realization transmission agency.

Operating principle of the present utility model is as follows: the core texture of known forced action type seal floor drain mainly is made up of elastic body, plug members and valve body, and elastic body and plug members are formed link gear by rigid element.The utility model has added the accumulation chamber that the bottom has discharge orifice in the link gear that elastic body and plug members are formed, link with elastic body and plug members when accumulation chamber moves down.The design of this floor drain makes floor drain not have current fashionable, floor drain is in closed condition, elastic body has an initial compression displacement, this displacement makes elastic body produce expansion force, because elastic body is by drive disk assembly and plug members interlock, so this expansion force makes obstruction and valve body lower end contact surface produce sealing load.During the floor drain draining, accumulation chamber finally is full of water, and its suffered gravity is compressed elastic body, and plug members moves down.Because the gravity of filling the accumulation chamber of water is constant, so the distance of elastic body compression is constant, and the downward displacement of plug members also is constant, and floor drain is stable to be opened thereby make.When water stops to flow into floor drain, the water in the final accumulation chamber is by the discharge orifice emptying, and under the effect of elastic force, plug members moves up and recovers to close until floor drain.

Concrete course of action is as follows: during the floor drain draining, flowing water enters accumulation chamber (5) through the water conservancy diversion of deflector (3), the water yield that enters accumulation chamber (5) is much larger than the water yield that flows out by accumulation chamber bottom discharge orifice, the moisture storage capacity of accumulation chamber (5) progressively rises, the action of gravity of accumulation chamber (5) is in axle (6), the upper cap nut (1) that is fixed in axle (6) top is exerted pressure to spring (2), spring (2) progressively compresses along with the water level in the accumulation chamber (5) rises, stopping up (7) moves down with axle (6), leave valve body (4) bottom, valve opening.When current continue to flow into floor drain, final accumulation chamber (5) will be filled water, and make spring (2) be subjected to a constant compressive force, produce constant compression displacement, floor drain is in stable opening, current flow into accumulation chamber (5) by deflector (3), and overflow from accumulation chamber (5), discharge by valve body (4) bottom.Under the dewatering installation opening, if water stops to flow into, the moisture storage capacity in the accumulation chamber (5) will gradually reduce owing to the discharge orifice earial drainage, and spring (2) stops up (7) and moves up the valve final plant closure with axle (6) because suffered pressure reduces and progressively elongation.Floor drain relies on the tension force of spring (2) to produce sealing load the most at last, makes obstruction (7) compress valve body (4) bottom end seal face and realizes sealing.

When this locality is omitted water in printing, compare with the hydrolock floor drain, water is straight-through discharges, and discharge pressure is big; When closing,, the better seal effect is arranged, can effectively prevent to gather in the sewer the overflowing of foul smell, backing up of sewage and toy and climb into because spring has applied pressure to the contact surface that stops up with the valve body bottom.The opening force of this device valve is constant, makes valve can be in stable opening.
