Turning plate type floor drain

Abstract

The invention provides a flap plate-type floor drain and belongs to the technical field of building. The floor drain solves the problems that the prior flap plate-type floor drain is easy to remain strain on the sealing surface to cause untight sealing. The flap plate-type floor drain comprises a cylindrical main body; an upper port of the main body is provided with a panel; a lower port is hinged with a sealing plate which can form sealing with the lower port under the gravity function; the outer side of the main body is provided with a shell; the inside of the lower port of the main body isof a conic shape, namely conic surface 1; and the outer edge of the sealing plate is of a conic shape which is matched with the conical surface 1, namely conical surface 2. The inner edge of the lower port is sealed and is of a conic shape and can prevent the strain from remaining on the sealing surface. The flap plate-type floor drain has the advantages of high sealing performance and free cleaning.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to sanitary equipment, in particular to a flap type floor drain. Background technique [0002] The floor drain is installed at the port of the indoor and outdoor drainage pipes to prevent pests, odors, etc. from overflowing from the drainage pipes, so as to avoid affecting the ambient air quality and environmental sanitation. [0003] At present, there are many kinds of known floor drains with different structures, but there are more or less problems. For example: 1. Float-type water-sealed floor drain: A plastic ball is used to seal the drain, but the sealing effect is not satisfactory. The water evaporation causes the float to fail to float, and the seal fails. It needs to be cleaned after a long time. 2. Springboard floor drain: The structure is not reasonable, and the seal of the springboard material used is not tight, and the effect is not ideal. Some with water seals are e...

AI Technical Summary

Problems solved by technology

For example: 1. Floating ball water-sealed floor drain: A plastic ball is used to seal the drain, but the sealing effect is not ideal. The water evaporation causes the floating ball to fail to float, and the seal fails. It needs to be cleaned after a long time.

2. Springboard floor drain: The structure is not reasonable, and the seal of the springboard material used is not tight, and the effect is not ideal. Some with water seals are easy to make hair entangle the springboard, causing seal failure, and the sealing effect cannot be achieved.

3. Eccentric block type floor drain: the seal is not tight, the pin is very easy to damage, it is easy to cause failure, and the service life is not long

4. Magnet floor drain: use two magnets to attract each other to seal. The magnetic force of the magnet in the sewage is not as stable as that in the air, and the surface water quality is very bad. For reasons such as brushing the ground, the sewage will contain some iron impurities that will be absorbed. On the magnet, the gradual accumulation will cause the gasket to be unable to close. In addition, due to the effect of the earth's large magnetic field, the magnetic force will gradually decay, and it will lose its performance after a long time.

5. Piston-type floor drain: use two sets of times to drive the piston to play the role of upper and lower sealing, but the actual sealing performance is not good, and the structure is too complicated, requiring frequent cleaning and maintenance

6. Spring-type floor drain: it is sealed with a spring stretching gasket. Since the spring is made of boron iron, it is easy to rust. After a long time, the elasticity gradually loses until it breaks and fails, and the service life is short

The sealing surface of this structure is on the bottom surface of the bottom hole of the valve body, parallel to the sealing surface of the floor drain cover, it is difficult to be washed, and when a small amount of sewage enters the floor drain, the stains are easy to stick to the sealing surface, over time Over time, when the stains accumulate to a certain amount, the seal will not be tight if it is not cleaned in time
