Description

Tap water supplementary pressure water supply steady flow tank

technical field

The utility model relates to the field of tap water supply equipment, in particular to a tap water supplementary pressure water supply steady flow tank which can replace a water storage tank in building water supply equipment.

Background technique

Building (especially high-rise building) water supply all is at present by pouring tap water into the open, pressureless reservoir, then water pump pumps to the roof, and then flows into the method water supply of building indoor tap water pipe network. The disadvantages are: 1. It is unhygienic, and the open reservoir is easy to breed bacteria and red worms, and it will fall into dust; 2. The reservoir is open and pressureless, so the pressure of tap water is wasted, and it is necessary to use a pump to pump water up , wasting electricity and increasing water costs.

Contents of the invention

The task of this utility model is to overcome the defects in the above-mentioned prior art, and to design a steady flow tank for a new type of tap water supplementary pressure water supply device that can use the pressure of the tap water pipe network to realize sanitation, energy saving, and low-cost water supply

The technical scheme of the utility model is:

A steady flow tank for tap water supplementary pressure supply, characterized in that the steady flow tank contains a liquid-tight tank body, the tank body is provided with tap water inlet, outlet, liquid level sensor and electric remote pressure gauge, on the top of the tank body There is also a vacuum exhaust/intake port, and a valve cover is arranged on the vacuum exhaust/intake port.

The tap water inlet and the electric remote pressure gauge are arranged at the top of the tank body, and the outlet is arranged at the bottom of the tank body.

Utilizing the tap water supplementary pressure water supply steady flow tank of the utility model, combined with devices such as water pumps and air pressure tanks, a novel tap water supplementary pressure water supply device that can make full use of tap water pressure to realize energy saving, sealing, and pollution-free supplementary pressure water supply can be formed.

Below in conjunction with accompanying drawing and embodiment the utility model and its usage are described in detail.

Detailed ways

A horizontal (can also be vertical) tap water supplementary pressure water supply steady flow tank, as shown in Fig. Port 14, liquid level sensor 4 and electric remote pressure gauge 5 are also provided with a vacuum exhaust/air inlet 6 on the top of the tank body 1, and a valve cover 7 is arranged on the vacuum exhaust/air inlet 6. The tap water inlet 2 and the electric remote transmission pressure gauge 5 are arranged at the top of the tank body 1, and the outlet 3 is arranged at the bottom of the tank body 1.

Shown in Fig. 2 is that the utility model is concretely applied in tap water supplementary pressure water supply equipment, wherein contains a tap water supplementary pressure supply water steady flow tank 1 ' shown in Fig. 1. The outlet 3 is connected to the inlets of two or three parallel water pumps 9 connected with check valves 10, the outlets of the water pumps 9 are connected to the upper water pipe network 12, and a bypass check valve is provided between the outlet 3 and the upper water pipe network 12 13; An air pressure tank 11 is provided between the outlet of the water pump 9 and the water supply pipe network 12; the liquid level sensor 4, the electric remote pressure gauge 5, and the water pump 9 are connected to the signal detection controller 8. The signal detection controller 8 is provided with an AC frequency conversion speed regulator capable of controlling the water pump 9 .

The working principle is: the water of the tap water pipe network first enters the utility model tap water supplementary pressure water supply steady flow tank 1 ', the air in the tank body 1 pushes open the valve cover 7, and is discharged from the vacuum exhaust/air inlet 6. After the water was full, the valve cover 7 was automatically closed. When the pressure of the tap water pipe network can meet the water requirements, the system will directly supply water to the water pipe network through the bypass check valve 13; The frequency conversion controller of the controller 8, the water pump runs, and automatically adjusts the speed and constant pressure water supply according to the water consumption. If the running water pump reaches the power frequency speed, the other water pump is automatically put into frequency conversion operation. When the water pump supplies water, if the water volume of the tap water pipe network is greater than the flow rate of the water pump, the system maintains normal water supply; when the water volume of the tap water pipe network is less than the flow rate of the water pump during the peak water consumption, the water in the steady flow tank can still supply water normally as a supplementary water source. At this time, The air enters the steady flow tank through the valve cover 7, and the liquid level in the tank continuously drops to the set water level. The liquid level detector feeds back the signal to the frequency conversion controller, and the water pump stops automatically to protect the water pump unit. When water is supplied at night with a small flow rate and the pressure of the tap water pipe network cannot meet the requirements, the air pressure tank can store and release energy, avoiding frequent start-up of the water pump.
