CN2714645Y - Storage water free ball float type air-barrier draining valve - Google Patents

Abstract

The utility model discloses a storage water free ball float type air-barrier drain valve. A free ball float type air-barrier drain valve is composed of an infundibular drain valve body and an air floating ball, the upper part of the drain valve body is a conic water through bucket, the lower part is a water discharging opening and a water outlet pipe. The inner part of the drain valve is a float type air-barrier ball which can be floated by water and can freely rise and fall, and the float type air-barrier ball is floating covered on a drain opening. When the sewerage entering into the drain valve body, the float type air-barrier ball can be floated by packing water with the action of water buoyancy, so the sewerage can be exhausted through the water outlet pipe via the drain opening. After the complete exhausting of the sewerage, the float type air-barrier ball can naturally fall on the drain opening and seal the drain opening. No matter the drain valve is provided with packing water or not, the utility model has the functions of effective draining and air separating.

Description

No water ball float gas-insulation drain valve

Technical field the utility model relates to a kind of no water ball float trapping dewatering installation, especially outstanding not water and ball float trapping function.

Background technology is present, it all is to adopt the draining trapping facility that has trap trapping structure that known washroom makes the dewatering installation of 1 usefulness, as: the draining trapping system of floor drain, wash basin, bathtub and lavatory pan has trap and outfall in the bottom of main body.Need in use often to keep having in the trap a certain amount of water to exist,, reach draining and the purpose of trapping in order to form water seal.But after the water amount in the trap reduced to a certain degree, the trapping function of this drainage system just disappeared.And, very easily shelter evil people and countenance evil practices in the trap.

The deficiency that summary of the invention makes the trapping defunctionalization of air isolation bowl in order to overcome the water amount of existing floor drain in trap and to reduce, the utility model provides a kind of no water ball float gas-insulation drain valve, this no water ball float gas-insulation drain valve is effluent sewerage successfully, and can still keep the trapping function under the state of no water.The technical scheme that its technical problem that solves the utility model adopts is: in the trapping ball float draining valve of being made up of infundibulate draining valve main body and trapping ball float, draining valve main body top is that cone shape is crossed bucket, and the bottom is outfall and gutter.The inside of draining valve is one only to be floated and the trapping ball float of free lifting by water, and trapping ball float floating ground covers on outfall.

The beneficial effects of the utility model are: no matter have or not water in this draining valve, all possess effective draining and trapping function.

Description of drawings further specifies the utility model below in conjunction with drawings and Examples.

Fig. 1 is just (thoroughly) view that the utility model is embodied as no water ball float trapping floor drain;

Fig. 2 is top (thoroughly) view of Fig. 1;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is A '-A ' sectional view that the utility model is embodied as the ball float gas-insulation drain valve of wash basin, bathtub;

Among the figure: 1. the floor drain lid of combing, 2. draining valve main body, 3. gutter, 4. trapping ball float, 5. outfall is 6. combed and is covered scupper, 7. the lower body part interface of wash basin, bathtub or lavatory pan.

The specific embodiment is embodied as among the embodiment of no water ball float trapping floor drain at the utility model shown in Figure 1, floor drain comb lid (1) covers on infundibulate draining valve main body (2), inside in draining valve main body (2), trapping ball float (4) floating ground covers on outfall (5).Enter in the draining valve main body (2) as sewage, trapping ball float (4) is floated by water under the buoyancy of water effect, sewage is discharged through gutter (3) by outfall (5), after sewage is all discharged, trapping ball float (4) drops on outfall (5) naturally and goes up (as Fig. 3), and outfall (5) is sealed.

Be embodied as in the A '-A ' sectional view of the ball float gas-insulation drain valve of wash basin, bathtub or lavatory pan bottom at the utility model shown in Figure 4, the lower body part interface (7) of wash basin, bathtub or lavatory pan closely is connected on the draining valve main body (2), inside in the draining valve main body, trapping ball float (4) floating ground covers on outfall (5), promptly constitutes complete no water ball float trapping drainage system.

Claims (1)

1. A kind of no water ball float gas-insulation drain valve, in the ball float gas-insulation drain valve of forming by infundibulate draining valve main body and trapping ball float, draining valve main body top is that cone shape is crossed bucket, the bottom is outfall and gutter, it is characterized in that: the inside of draining valve is one only to be floated and the trapping ball float of free lifting by water, and trapping ball float floating ground covers on outfall.
