Description
Technical field
This utility model relates to pump non-negative pressure frequency-changing water supply device in a kind of semi-submersible type tank, belongs to automatic water supply device field.
Background technology
Existing most non-negative pressure frequency-changing water supply device all uses traditional vertical pump, vertical steady-flow tank, vertical vacuum tank, base, pipe valve etc. to be combined into complete set equipment.Ye You minority producer uses submersible pump to be placed in tank or in pipe.The outer distribution pump structure of tradition is complicated, and floor space is many, and noise vibration is big, but submersible pump mode there is also the shortcomings such as quality guarantee period is short, the life-span is short, dismounting is inconvenient.
Utility model content
The technical problems to be solved in the utility model is: providing a kind of rational in infrastructure, floor space is few, convenient installation, maintenance, and pump non-negative pressure frequency-changing water supply device in the semi-submersible type tank that can increase the service life.
Pump non-negative pressure frequency-changing water supply device in semi-submersible type tank described in the utility model, including steady-flow tank and outfall sewer, steady-flow tank tank body side arranges water inlet, installing semi-submersible type pump in steady-flow tank, semi-submersible type pump water inlet mouth is placed in steady-flow tank, and outlet passes sequentially through out Water Check Valve, outlet valve and ball valve and is connected with outfall sewer, in steady-flow tank, vacuum tank is installed in middle and lower part, connecting outfall sewer by water pipe bottom vacuum tank, anti-negative pressure valve one end is arranged on steady-flow tank top, and the other end connects outfall sewer.
When municipal tap water enters in tank through steady-flow tank water inlet, the original air in tank constantly raises with water level and forces anti-negative pressure valve discharge；When water level is increased to design the upper limit, in tank, air is arranged light, and anti-negative pressure valve is automatically switched off；Now the pressure in steady-flow tank is equal with the pressure of municipal tap water；Now turn on pump, semi-submersible type pumping takes the water in steady-flow tank, in outfall sewer enters system and user.When system pressure value is increased to vacuum tank the blowing pressure value, in the water not only entrance system got out, also into warehousing pressure water in vacuum tank.When in system, pressure is higher than setup pressure value, equipment quits work, if there being a small amount of water in system, equipment is not opened；Carried out the pressure loss of a small amount of water in replenishment system by the press water of vacuum tank stock, play energy-conservation effect；When system and user use water in a large number, and when system pressure drops to set low pressure limit, equipment automatically turns on, and recovers normal water supply state.When user is at water use peak, when municipal tap water pressure flow can not meet user's maximum water consumption, steady-flow tank pressure declines, and water level decreasing, anti-negative pressure valve automatically opens up, it is therefore prevented that the generation of negative pressure.If municipal tap water pressure flow continues to decline, equipment quits work.After municipal tap water pressure flow recovers, equipment can automatically turn on, and recovers normal water supply state.
Described semi-submersible type pump is set to two, and is symmetricly set on the both sides of anti-negative pressure valve.
The beneficial effects of the utility model are:
Compact conformation is scientific and reasonable, and floor space is few compared with traditional structure, and noise is low；This structure is compared with submersible pump, it is simple to installs, dismantle, overhaul, extends service life；One tank is multiplex, and constant current constant voltage saves inlet pipeline, without base, saves material, reduces production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In figure: 1, anti-negative pressure valve 2, semi-submersible type pump 3, outfall sewer 4, steady-flow tank 5, vacuum tank 6, water pipe 7, water inlet 8, ball valve 9, outlet valve 10, go out Water Check Valve.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As shown in Fig. 1～Fig. 2, pump non-negative pressure frequency-changing water supply device in semi-submersible type tank described in the utility model, including steady-flow tank 4 and outfall sewer 3, steady-flow tank 4 tank body side arranges water inlet 7, semi-submersible type pump 2 is installed in steady-flow tank 4, semi-submersible type pump 2 water inlet is placed in steady-flow tank 4, outlet passes sequentially through out Water Check Valve 10, outlet valve 9 and ball valve 8 and is connected with outfall sewer 3, in steady-flow tank 4, vacuum tank 5 is installed in middle and lower part, outfall sewer 3 is connected by water pipe 6 bottom vacuum tank 5, anti-negative pressure valve 1 one end is arranged on steady-flow tank 4 top, and the other end connects outfall sewer 3.Semi-submersible type pump 2 is set to two, and is symmetricly set on the both sides of anti-negative pressure valve 1.
During use, when municipal tap water enters in tank through the water inlet 7 of steady-flow tank 4, the original air in tank constantly raises with water level and forces anti-negative pressure valve 1 discharge；When water level is increased to design the upper limit, in tank, air is arranged light, and anti-negative pressure valve 1 is automatically switched off；Now the pressure in steady-flow tank 4 is equal with the pressure of municipal tap water；Now turn on pump, semi-submersible type pump 2 extracts the water in steady-flow tank 4, in outfall sewer 3 enters system and user.When system pressure value is increased to vacuum tank 5 the blowing pressure value, in the water not only entrance system got out, also into warehousing pressure water in vacuum tank 5.When in system, pressure is higher than vacuum tank 5 setup pressure value, equipment quits work, if there being a small amount of water in system, equipment is not opened；Carried out the pressure loss of a small amount of water in replenishment system by the press water of vacuum tank 5 stock, play energy-conservation effect；When system and user are in a large number with water, system pressure drops to vacuum tank 5 when setting low pressure limit, and equipment automatically turns on, and recovers normal water supply state.When user is at water use peak, when municipal tap water pressure flow can not meet user's maximum water consumption, steady-flow tank 4 pressure declines, and water level decreasing, anti-negative pressure valve 1 automatically opens up, it is therefore prevented that the generation of negative pressure.If municipal tap water pressure flow continues to decline, equipment quits work.After municipal tap water pressure flow recovers, equipment can automatically turn on, and recovers normal water supply state.
