Abstract

The utility model discloses a closed overflow device, which comprises an overflow pipe. One end of the overflow pipe is communicated with a water tank while the other end is communicated with a water drainage system, an overturning mechanism is arranged inside the overflow pipe, the overturning mechanism comprises a circular turning plate hinged on the inner wall of the overflow pipe, and a filter screen is arranged inside the lower end of the overflow pipe. The turning plate of the closed overflow device can seal the overflow pipe and can prevent foul gas, surrounding air and the like inside the water drainage system entering the water tank along the overflow pipe. When water in the water tank overflows, water flows converge on the turning plate inside the overflow pipe, after the converged overflow water accumulated to a certain height, the converged overflow water can resist gravity of a balance weight so as to lead the turning plate to overturn, and then the converged overflow water can flow to the water drainage system. In addition, the filter screw can prevent living beings climbing into the overflow pipe from the outside of the water drainage system to pollute the water tank.

Description

Airtight overflow mechanism

Technical field

The utility model is about a kind of overflow mechanism, more particularly, and about a kind of airtight overflow mechanism that is used for water tank.

Background technology

At present, the secondary water-supply of highrise building adopts as selecting frequency conversion water tank or box no negative pressure pattern for use at pump house (on the attic) water tank is installed, water works output come water to be introduced in the water tank with municipal administration, again according to user's user demand, water pump is after the water tank water intaking, and water flows into each water use sector.In order to guarantee overflowing of the too high back of water tank water level water, the top, side of water tank must be provided with opening, and the spill stream that opening can be used for feed tank goes out.

But opening part often is easy to generate various pollutions, is difficult to guarantee the sanitary condition of water tank, has brought potential safety hazard to the user.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of overflow water that can discharge in the water tank, and effectively prevents dirty gas and ambient air and the biological airtight overflow mechanism that enters water tank in the drainage system.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of airtight overflow mechanism, include bleed off pipe, one end of described bleed off pipe is connected with water tank, the other end is connected with drainage system, be provided with switching mechanism in the described bleed off pipe, described switching mechanism includes the circular turnover panel that is hinged on the bleed off pipe inwall, and the inside, lower end of described bleed off pipe is provided with filter screen.

Hinged two pin joints of the turnover panel of described switching mechanism and bleed off pipe inwall are with the circumference separated into two parts of turnover panel, and two-part circular arc ratio is 1: 2.

Described switching mechanism also includes the counterweight that is arranged on the turnover panel top, and described counterweight is positioned at the position, roundlet arc limit near turnover panel.

Described switching mechanism also includes and is arranged on the outer sealing ring of turnover panel circumference.

Described sealing ring is the non-constant section structure.

The cross section of the sealing ring of the position, roundlet arc limit of described turnover panel diminishes from top to bottom.

The cross section of the sealing ring of the position, orthodrome limit of described turnover panel becomes big from top to bottom.

Adopt the beneficial effect after the technique scheme to be: the turnover panel of airtight overflow mechanism of the present utility model can seal bleed off pipe, can prevent that the dirty gas etc. in the drainage system from entering water tank along bleed off pipe; When water tank overflows water, on the turnover panel of channelling of flow in bleed off pipe, converge overflow water and build up to some after, can overcome the gravity of counterweight, make the turnover panel upset, thereby make the overflow water that converges flow to drainage system; In addition, the filter screen of setting can prevent that biology from climbing into bleed off pipe and then water tank is produced pollution from drainage system.

Description of drawings

Fig. 2 is the connection diagram of the bleed off pipe and the switching mechanism of airtight overflow mechanism in the utility model;

Fig. 3 is the schematic side view of the switching mechanism of airtight overflow mechanism in the utility model.

Wherein, 1 bleed off pipe, 2 water tanks, 3 drainage systems, 4 turnover panels, 5 filter screens, 6 counterweights, 7 sealing rings.

The specific embodiment

Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.

As shown in Figure 1, airtight overflow mechanism of the present utility model, include bleed off pipe 1, one end of bleed off pipe 1 is connected with water tank 2, the other end is connected with drainage system 3, is provided with switching mechanism in the bleed off pipe 1, and described switching mechanism includes the circular turnover panel 4 that is hinged on bleed off pipe 1 inwall, the inside, lower end of bleed off pipe 1 is provided with filter screen 5, and the effect of filter screen 5 is to prevent that biology from climbing into bleed off pipe 1 and then may produce pollution to water tank 2 from drainage system 3.

As shown in Figure 2, hinged two pin joints of turnover panel 4 and bleed off pipe 1 inwall are with the circumference separated into two parts of turnover panel 4, and two-part circular arc ratio is 1: 2.

Described switching mechanism also includes the counterweight 6 that is arranged on turnover panel 4 tops, and counterweight 6 is positioned at the position, roundlet arc limit near turnover panel 4, as shown in Figure 2.

Described switching mechanism also includes and is arranged on the outer sealing ring 7 of turnover panel 4 circumference, sealing ring 7 can be the prismatic shapes structure, also can be non-constant section structure as shown in Figure 3, the cross section of sealing ring 7 that is positioned at the position, roundlet arc limit of turnover panel 4 diminishes from top to bottom, the cross section of sealing ring 7 that is positioned at the position, orthodrome limit of turnover panel 4 becomes greatly from top to bottom, helps the upset of turnover panel 4 more.

Airtight overflow mechanism of the present utility model in use, turnover panel 4 is bleed off pipe 1 sealing, can prevent that the dirty gas etc. in the drainage system 3 from entering water tank 2 along bleed off pipe 1.When water tank 2 overflows water, on the turnover panel 4 of channelling of flow in bleed off pipe 1, converge overflow water and build up to some after, can overcome the gravity of counterweight 6, make turnover panel 4 upsets, thereby make the overflow water that converges flow to drainage system 3.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
