Description

Overflow valve for isolating air

Technical Field

The invention relates to the field of bathrooms, in particular to an overflow valve for isolating air.

Background

In the prior art, an overflow pipe on the side edge of a drainage valve of a closestool is communicated with a drainage outlet at the bottom of the drainage valve. Under the normal stagnant water state, the outside air passes through overflow pipe and drain valve base outlet intercommunication. When the overflow phenomenon occurs, water flows from the overflow pipe to the water discharge valve base water discharge port and enters the toilet bowl pipeline. When the drain valve is opened, water flows out through the drain outlet of the drain valve base, and when the drain valve is normally used, the drain outlet of the drain valve base is communicated with outside air through the overflow pipe channel, negative pressure can be generated in the drain channel during draining, and air can be mixed into the drain outlet of the drain valve base together under the action of outside atmospheric pressure, so that the drain channel is not in a pipe full water state, and the drainage speed is reduced.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide an air-isolating relief valve, which can isolate a drain outlet of a drain valve from outside air to increase a drain speed of the drain valve.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

an air isolation overflow valve includes an overflow body, a float, and a seal. The overflow device is characterized in that a cavity is formed in the overflow body, and a water inlet pipe and a water outlet pipe which are communicated with the cavity are fixedly arranged at the top and the bottom of the overflow body respectively. The floating barrel is arranged above the overflow body, a guide column is fixedly arranged at the bottom of the floating barrel, a guide sleeve used for radially limiting the guide column is fixedly arranged in the overflow body, and one end of the guide column penetrates through the guide sleeve and extends into the cavity. The sealing element is fixed at the bottom of the guide post, and the bottom of the sealing element is in sealing fit with the top of the drain pipe.

The sealing joint comprises a bottom plate, a connecting part fixedly arranged at the top of the bottom plate and used for being connected with the guide column, and a mounting part fixedly arranged at the bottom of the bottom plate and used for fixedly mounting the sealing element.

Preferably, the sealing element is a sealing rubber gasket.

Preferably, in order to achieve a better sealing effect, the top of the drain pipe extends upwards to form a ring of annular protrusion, and the bottom of the sealing rubber gasket is in sealing fit with the annular protrusion.

Furthermore, in order to realize the water supplementing function, a flow guide pipe used for communicating the water supplementing pipe with the interior of the water drainage pipe is fixedly arranged on the side wall of the water drainage pipe.

The drainage pipe is arranged in the water storage pipe, the drainage pipe is bent upwards to form a water storage branch pipe, a water replenishing elbow joint is detachably mounted at the top of the water storage branch pipe, and a water outlet of the water replenishing elbow joint is arranged in a downward inclined mode. When the overflow valve is used for replenishing water, a water storage bay is formed among the water replenishing elbow joint, the water storage branch pipe, the flow guide pipe and the water replenishing pipe, and external air can be isolated from water stored in the water storage bay and enters the overflow port. Meanwhile, the water replenishing elbow joint can have different inner diameter specifications, different water replenishing rates can be realized, and the water replenishing elbow joint with the proper inner diameter can be selected and matched according to the water replenishing quantity of the toilet. The delivery port downward sloping setting of moisturizing elbow joint can avoid the moisturizing rivers to break away the flotation pontoon when too big to cause sealed inefficacy, simultaneously, the existence of moisturizing elbow joint can let the water effect of depositing of trapped water bay better.

Furthermore, the top opening of flotation pontoon, bottom downwardly extending form the round and are used for the cover to establish the cyclic annular division board in the inlet tube top outside. The arrangement of the annular isolation plate can increase the buoyancy of the buoy, accelerate the floating speed of the buoy and facilitate the improvement of the overflow capacity.

Furthermore, the uide bushing fix inside the overflow body through a plurality of spinal branch vaulting poles, the one end of bracing piece with the outer wall rigid coupling of uide bushing, the other end is fixed on the inner wall of inlet tube.

Furthermore, in order to further strengthen the strength of the guide pillar and improve the guiding effect, a plurality of guiding ribs are arranged on the outer wall surface of the guide pillar along the length direction.

Further, in order to realize better dismouting, make the production technology of each subassembly simpler simultaneously, the overflow body include overflow base and lock and be in overflow upper cover on the overflow base, the drain pipe with the overflow base is the integrated into one piece structure, the inlet tube with the overflow upper cover is the integrated into one piece structure.

The invention has the following beneficial effects:

1. under the normal condition, the sealing member has kept apart the drain valve outlet and has communicated with each other with the outside air because of the gravity action and the sealed cooperation in drain pipe top of flotation pontoon, and the outside air can't enter into the drain port from the inlet tube, and the outlet is in full pipe water state almost, makes drainage speed improve by a wide margin through the siphon effect. When the water level overflows the floating cylinder by a certain height, the floating cylinder floats upwards, and the sealing element is separated from the sealing surface of the drain pipe to realize overflow.

2. Through setting up honeycomb duct, water storage branch pipe and detachable moisturizing elbow joint in drain pipe department, during the overflow valve moisturizing, constitute a trap between moisturizing elbow joint, water storage branch pipe, honeycomb duct and the moisturizing pipe, in the external air entering overflow mouth can be kept apart to retaining in the trap to avoid in running into the drain valve drain because of the air, cause the drainage speed to reduce. Meanwhile, the water replenishing elbow joint can have different inner diameter specifications, different water replenishing rates can be realized, and the water replenishing elbow joint with the proper inner diameter can be selected and matched according to the water replenishing quantity of the toilet. The delivery port downward sloping setting of moisturizing elbow joint can avoid moisturizing rivers to break away the sealing member when too big to cause sealed inefficacy, simultaneously, the existence of moisturizing elbow joint can let the water effect of depositing of trapped water bay better.

3. Set up a plurality of direction ribs on the guide pillar outer wall face, can reduce the area of contact between guide pillar outer wall face and the guide bush inner wall face, also can prevent when having reduced frictional force that the dead risk of card appears in the guide pillar for the upper and lower activity of guide pillar is more smooth and easy.

4. The overflow valve of the invention can be arranged in the overflow pipe of the drain valve to realize the functions of isolating air and overflowing, and can also be independently arranged at the bottom of the water tank to realize the functions of overflowing and water replenishing.
