Description

A combined mechanical seal and water seal floor drain

technical field

The invention relates to a floor drain, in particular to a floor drain combined with a mechanical seal and a water seal.

Background technique

As an important device to remove ground water, the floor drain plays an important role in building drainage. The floor drain should have two basic functions: one is smooth drainage, which can quickly remove the accumulated water on the ground; the other is good sealing, which can effectively prevent the odor in the sewer pipe from entering the room. The common problems of existing floor drains are mainly manifested in: ①The height of the water seal of the floor drain is not enough, most of them are only 10-30mm, and it is easy to dry up, causing the floor drain to lose its sealing effect, and the odor in the drainage pipe enters the room; ②The drainage capacity of the floor drain Weak, prone to poor drainage; ③The self-cleaning ability of the floor drain is poor, and it is easy to catch hair, deposit sludge, and form blockage; Positive and negative pressure destruction.

Contents of the invention

The object of the present invention is to provide a mechanical seal and water seal combination floor drain with simple structure, small water flow resistance, good sealing effect and not easy to block.

The combined mechanical seal and water seal floor drain of the present invention is mainly composed of a floor drain cover, a floor drain body, a float and a hose type magnetic seal valve. The floor drain cover is fixed on the floor drain main body through threaded connection, buckle connection or other connection methods, and the floor drain cover has a water inlet hole, and ground water enters the floor drain main body through the water inlet hole. There is a float in the main body of the floor drain, and the lower end of the float matches the water outlet of the main body of the floor drain, and the purpose of making the float close the water outlet of the main body of the floor drain can be achieved by using gravity or magnetic force; the gravity required for the float to close the water outlet of the main body of the floor drain is determined by the gravity of the float itself or The gravity generated by the counterweight provides the required magnetic force by a magnetic seal assembly installed at the lower end of the float and the water outlet, and the float and the main body of the floor drain can also be made of magnetic materials. The magnetic force between the magnetic seal assembly can act on several points around the water outlet, and can also act on the ring around the water outlet; the magnetic seal assembly is made of magnetic materials, including hard magnetic and soft magnetic, and the magnetic force can Produced by magnetic materials of various shapes. In order to increase the sealing effect, an elastic sealing ring can be installed at the lower end of the float or at the sealing place of the water outlet. When the magnetic material is rubber magnet, the elastic sealing ring can be omitted. The buoyancy generated by the float is compatible with gravity or magnetic force, taking into account the drainage performance and sealing performance of the floor drain; the guide or positioning device of the float can be installed on the floor drain cover or the main body of the floor drain to enhance the sealing effect of the floor drain; the top of the float can also be installed The deflector is used to prevent the large water flow discharged from the washing machine from directly impacting the float and affecting the drainage performance of the floor drain. A hose-type magnetic sealing valve is installed on the water outlet of the floor drain body, and the water outlet is sealed by magnetic force. The opening of the hose-type magnetic sealing valve depends on the gravity or impulse of water.

The beneficial effect of the invention is that the combined floor drain of the mechanical seal and the water seal can be opened and closed quickly, the resistance is small when the water flows through, it is not easy to be blocked, the sealing effect is good, the self-cleaning ability is strong, and the use and maintenance are convenient. Since the floor drain has upper and lower mechanical seals and a water seal on each of the mechanical seals, the positive and negative pressure in the sewer pipe will not affect the sealing performance of the floor drain, and the floor drain also has good anti-backflow performance.

Detailed ways

Referring to the accompanying drawings, the combined mechanical seal and water seal floor drain consists of a floor drain cover 1 , a floor drain body 2 , a float 3 , a magnetic seal assembly 4 , a magnetic seal assembly 5 and a hose type magnetic seal valve 6 . The floor drain cover 1 is installed on the floor drain main body 2 through threads, and water inlet holes are distributed on the floor drain cover 1 . The lower end of the float 3 matches the water outlet of the floor drain main body 2, and the float 3 can block the water outlet of the floor drain main body 2 when it sinks. The magnetic seal assembly 4 is fixed on the lower end of the float 3, the magnetic seal assembly 5 is fixed around the water outlet of the floor drain main body 2, and corresponds to the magnetic seal assembly 4, relying on the magnetic seal assembly 4 and the magnetic seal assembly 5 The magnetic force generated between them seals the water outlet of the floor drain main body 2; the magnetic seal assembly 4 is made of rubber magnet, which can strengthen the sealing effect; a hose type magnetic seal valve 6 is installed at the water outlet of the floor drain main body 2. The working process of the combined mechanical seal and water seal floor drain is as follows: the water flows into the floor drain main body 2 through the water inlet hole on the floor drain cover 1 and gathers around the float 3. When the buoyancy of the water gathered in the floor drain main body 2 is greater than that of the magnetic seal assembly When the sum of the magnetic force between 4 and the magnetic seal assembly 5 and the gravity of the float, the float 3 floats up instantly, and the water outlet of the floor drain main body 2 is opened, so that the water in the floor drain main body 2 quickly enters the hose type magnetic seal valve 6, and Open the hose type magnetic seal valve 6 and enter the sewer. Because the magnetic force received by the float 3 after floating up is very small, the water outlet of the floor drain main body 2 can be fully opened, and the water flow smoothly enters the hose type magnetic seal valve 6. Under the action of gravity and impulse of the water flow, the hose type magnetic seal valve 6 can also be opened smoothly, so that the solids contained in the water can all be discharged into the sewer. When the water flow becomes smaller, the water level in the main body of the floor drain 2 drops, and the float 3 also drops; when the float 3 falls within the range of the magnetic force, the float 3 instantly blocks the water outlet of the floor drain under the action of the magnetic force; if there is always When the small water flow enters the main body of the floor drain 2, the float 3 is intermittently opened; A certain amount of water will be stored and form a water seal. After no water enters in the hose type magnetic seal valve 6, the hose type magnetic seal valve 6 relies on magnetic force to seal the water outlet, and also has water storage in the hose type magnetic seal valve 6, and forms a water seal. If the floor drain enters without water for a long time, the water seal water in the floor drain main body 2 will evaporate to dryness. At this moment, the upper and lower mechanical seals and the water seal in the magnetic seal valve 6 still exist, and the floor drain is still in a completely sealed state.
