Abstract

The utility model relates to a flow distributor, in particular to a tap water flow distributor, the water inlet of which gradually becomes narrow. The distributor is a multi-way pipe structure which is provided with a water inlet pipe, a water adding pipe and a water outlet pipe, wherein, a taper pipe is arranged at the root part of the water inlet pipe and is connected with the water inlet pipe into a whole, so as to form a pipe-in-pipe structure, the water outlet of the water adding pipe faces the outer wall of the taper pipe, and a clearance is formed between the water outlet of the water adding pipe and the outer wall of the taper pipe; and a rectifying corner is arranged at the root part in the water outlet pipe. The flow distributor has simple structure, when the flow of the tap water pipe net is not enough, the water can be automatically added by the water pressure difference, thereby dispensing with external water adding devices such as a water adding pump, and saving the cost; when the flow of the tap water pipe net can ensure the system water consumption, the tap water flow distributor can automatically pump out a certain amount of water from the water tank, thereby achieving the automatic circulation function of the water tank, preventing the water from being polluted, and playing the good effect of environment protection.

Description

The tap water flow distribution device

Technical field

The utility model relates to a kind of flow distribution device, the tap water flow distribution device that particularly a kind of water intake narrows down gradually.

Background technique

When in the municipal water supply system during water shortage, need in water supply network, replenish certain water yield, could guarantee the hydraulic pressure in the water system like this.Present method for supplementing water is whether the hydraulic pressure of measuring in the water system earlier is lower than standard hydraulic pressure, if be lower than standard hydraulic pressure, then will water in the water supply tank be injected in the water system by water pump, this water supplementing method complicated operation, equipment needed thereby cost height, hydraulic pressure are regulated untimely, poor stability.In addition, when the flow of tap water pipe network can guarantee the system water amount, the water in the water tank will can not be used always, and overlong time will cause severe water pollution, influence living water.

The model utility content

Technical problem to be solved in the utility model provide a kind of simple in structure, with low cost, adopt open loop control mode to realize the tap water flow distribution device of automatic water supplement.

For solving the problems of the technologies described above, the utility model is realized as follows: tap water flow distribution device described in the utility model is a through-pipe structure more than, which is provided with intake pipe, water-adding pipe and outlet pipe; Root at intake pipe has a conical pipe and intake pipe to be connected as a single entity, and forms pipe in the pipe, and the water outlet place of water-adding pipe forms a slit over against the outer wall of conical pipe between the water outlet of water-adding pipe and the outer wall of conical pipe; It is stupefied that root in the outlet pipe is provided with rectification.

Described water-adding pipe can have many.

The outlet diameter of described conical pipe is determined as required.

The size in described awl slit is determined as required.

Good effect of the present utility model is: the utility model is simple in structure, when the underfed of tap water pipe network, can realize automatic water supplement by differential water pressures, has removed outside water replenishing devices such as small pump from, has saved cost; When the flow of tap water pipe network can guarantee the system water amount, the utility model also can be from the certain water yield of water tank Automatic Extraction, thereby reached the effect of water tank automatic cycle, prevented polluted water, had played the good result of environmental protection.

Embodiment

As shown in Figure 1, tap water flow distribution device described in the utility model is a through-pipe structure more than, which is provided with intake pipe 1, water-adding pipe 2 and outlet pipe 3; Root at intake pipe has a conical pipe 4 to be connected as a single entity with intake pipe 1, forms pipe in the pipe, and the water outlet place of water-adding pipe 2 forms a slit 6 over against the outer wall of conical pipe 4 between the outer wall of the water outlet of water-adding pipe 2 and conical pipe 4; Root in the outlet pipe 3 is provided with rectification stupefied 5.

Described water-adding pipe 2 can have many.

The outlet diameter of described conical pipe 4 is determined as required.

The size in described awl slit 6 is determined as required.

Working procedure of the present utility model is: tap water enters from 1 pipe of intaking, and the cross section of intake pipe 1 constantly reduces from outside to inside, makes under the situation of the same water yield and pressure, and is very fast in this water velocity of installing inner lowest calibre place; Because making, water outlet fast by water-adding pipe 2 water in the water tank being pumped out automatically of this place flows to outlet pipe 3 together with water inlet than small gap 6 places generation swabbing; The minimum sectional area of conical pipe 4 can be according to demand adjusted when producing, and slit 6 that should the place also is adjustable, and also having at later product can be according to the field condition Field adjustment, this minimum sectional area is big more, then water flow velocity is more little, thus just more little from the water tank suction water yield, on the contrary then big more; This slit 6, place is more little, and then the water yield from the water tank suction is more little under the situation of same water speed, otherwise then big more; Make this device play pumping action and must make the water speed at minimum sectional area place reach certain numerical value, this value is relevant with the size in this slit 6, place, and slit 6 is big more then to be required highly more to this value, and it is bigger to aspirate the water yield at this moment; Slit 6 is more little, and is then low more to the requirement of this value, and it is less that aspirate the water yield this moment.

Claims

1, a kind of tap water flow distribution device, it is characterized in that: it is a through-pipe structure more than, which is provided with intake pipe, water-adding pipe and outlet pipe; Root at intake pipe has a conical pipe and intake pipe to be connected as a single entity, and forms pipe in the pipe, and the water outlet place of water-adding pipe forms a slit over against the outer wall of conical pipe between the water outlet of water-adding pipe and the outer wall of conical pipe; It is stupefied that root in the outlet pipe is provided with rectification.

2, according to the described tap water flow distribution device of claim 1, it is characterized in that: described water-adding pipe can have many.
