Abstract

A tap water storage and supply device, which is composed of a piston-type water injection and discharge switch, a connecting pipe and a one-way check valve at the bottom of a high-level water tank. The switch flows into the water tank, and due to the effect of the buoy, the piston and the water flow, when the water in the water tank reaches a certain height, the water injection port is automatically closed. When the supply of tap water stops, the piston slides downward under the action of gravity and magnetic force, and opens the water injection port in the opposite direction, so that the water in the water tank flows out in the reverse direction through the original path, and the one-way check valve prevents backflow, so as to achieve the same effect when the water plant stops water. Can maintain the purpose of people's daily water use. It is suitable for self-prepared water source storage and supply device for people's daily life, residential buildings, office buildings and small enterprises.

Description

tap water storage

The utility model relates to a daily tap water storage and supply appliance.

At present, urban residents generally use tap water, but whenever the water plant is powered off or overhauled, the tap water supply will be interrupted for a certain period of time, and when some residential areas have pipeline failures that need to be repaired, some residents will also have no tap water supply. In order to overcome the situation of these water cuts, generally the water company notifies the water customer in advance to utilize the water container to store water to meet emergency needs. Although these measures have been adopted, there will be omissions, which will bring great inconvenience to people's lives, such as cooking without water, burning without water, bathing without water, etc. Therefore, many residents now use to build water storage tanks indoors for emergency use. These water storage tanks are all open. Pick. This shows that this water storage tank can not make the resident also can use clean and sanitary running water in time and conveniently when water is cut off.

The purpose of the utility model is to provide a tap water storage and supply device that can automatically provide clean water for a certain period of time for residents when the water is cut off, so as to facilitate people's daily life.

The technical scheme of the utility model is realized by arranging a piston-type water injection and discharging switch at the bottom of a high-level water tank and a one-way check valve at the water inlet pipe.

Compared with the prior art, the utility model has the following characteristics:

1. It can realize automatic water storage, and the water pressure of tap water will not affect the water storage, and there will be a certain amount of water storage under any circumstances.

2. Automatic water supply, when the tap water supply is interrupted, it will automatically supply water to the indoor pipeline, without having to activate the switch separately, it can maintain the indoor water appliances to work for a period of time.

3. Since the water tank is closed, the spare water is clean and hygienic.

4. In the case of tap water supply, the water pressure in the indoor pipeline remains unchanged. In the case of water cutoff, the indoor pipeline can also maintain a certain pressure of tap water supply.

5. Compact structure, basically no maintenance.

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

As shown in the figure, the utility model includes a high-level water tank 2, a one-way check valve 11, and a connecting pipe 17. A piston-type water injection and discharge switch is installed at the bottom of the water tank. The piston-type water injection and discharge switch includes an upper end cover 4, a casing 7, lower end cover 10, T-shaped sleeve 14 is also housed in sleeve pipe 7, the bottom edge of T-shaped sleeve 14 is pressed on the lower end of sleeve pipe 7 by lower end cover 10, the straight pipe of T-shaped sleeve 14 and There is a water passing ring between the casing pipes 7, two water passing annular grooves 9 are arranged on the bottom edge of the T-shaped casing pipe 14, and two water passing straight grooves 6 are also arranged on the straight pipe wall of the T-shaped casing pipe 14. A magnet block 8 is bonded to the bottom of the straight pipe of the T-shaped sleeve 14, and a piston 5 is also arranged in the T-shaped sleeve 14. The middle part of the piston 5 is made of light foam material, the bottom is an iron plate 15, and the upper part is Rubber gasket 16, the weight of the whole piston 5 and the connecting rod 13 connected with it is slightly larger than the floating of water to it, the piston connecting rod 13 is connected with the buoy 1 in the water tank by a soft rope, and the whole piston 5 can be placed in a T-shaped sleeve. Do reciprocating motion in the straight pipe of pipe 14. The bottom of the inner cavity of the upper end cover 4 has a raised water injection port 12, and the top end of the upper end cover 4 is provided with four small water injection holes 3 evenly distributed.

The working principle is as follows: when the high-level water tank 2 is dry, the piston 5 is attracted by the magnet 8, the water flows in through the one-way check valve 11, and enters the piston-type water injection and discharge switch through the connecting pipe 17, and the water flows through the ring groove 9 and the straight groove 6. The water injection port 12 and the small water injection hole 3 enter the water tank 2. When the water is filled to a certain height, due to the buoyancy of the buoy 1 and the jacking effect of the water injected into the small hole 3, it will pass through the soft rope and the connecting rod. 13. Pull the piston 5 away from the magnet block 8. Due to the thrust of the water flow, the piston 5 will be quickly pushed to the water injection port 12, and the rubber gasket 16 on the piston 5 will be pressed tightly against the edge of the raised water injection port 12. Thereby play the effect of sealing water tank, and now the soft rope in the water tank 2 is in slack state. When the tap water supply is interrupted, the one-way check valve 11 works so that the water cannot flow backwards. At this time, the pressure of the water flow pressing the bottom of the piston 5 disappears. Under the potential energy of the water in the high water tank 2 and the gravity of the piston 5 and the connecting rod 13, Simultaneously because the soft rope in the water tank 2 is in a slack state, the piston 5 will slide downward, and the water in the high-level water tank 2 will flow through the water injection hole 3, the water injection port 12, the straight groove 6, the ring groove 9, and the connecting pipe 17. Indoor water pipes flow out. Thereby play the effect that also can maintain people's daily water demand when water is cut off.

The piston type water injection and discharge switch can also be used as a water injection switch in a flush toilet in a bathroom.
