It is interior, there is gap 7, the water outlet 8 of the water inlet pipe 5 is towards tank between the outer wall of the water inlet pipe 5 and the inner wall of outlet pipe 6
1 top of body, the water inlet 9 of the water inlet pipe 5 and the outlet 21 of outlet pipe 6 are horizontal direction disengaging.
The water outlet 8 of the water inlet pipe 5 is vertically upward and towards the top of tank body 1.
The vacuum suppresser 4 includes outer outlet body 10 and interior cover 11, and the interior cover 11 is in outer outlet body 10, inner cover
Body 11 includes shell 12, upper cover body 13 and lower cover 14, and the upper cover body 13 is set to the upper end of shell 12 and upper cover body 13 passes through
Bolt is fixed on the flange 15 of shell 12, and sealing ring 16 and air-filtering membrane 17 are accompanied between upper cover body 13 and flange 15,
Sealing ring 16 is in the upper layer of air-filtering membrane 17, and the center of the upper cover body 13 is equipped with through-hole 18, the centre bore of sealing ring 16
19 Corresponding matching through-holes 18；The lower cover 14 is fixedly mounted on the lower end of shell 12, and lower cover 14 is equipped with several stomatas
20, and pilot hole 22 is equipped at the center of lower cover 14；First chamber 23 is formd in the interior cover 11, at a floating ball 24
In in first chamber 23, and guide rod 25 is equipped on floating ball 24, the guide rod 25 passes through pilot hole 22；The outer outlet body 10
It is fixedly mounted on tank body 1, and forms second chamber 26 between interior cover 11, the second chamber 26 is connected with exhaust pipe
27。
It makes an explanation below to the working principle of the non-negative pressure stabilized compensating tank of the internal-circulation type of the utility model:
The non-negative pressure stabilized compensating tank of the internal-circulation type of the utility model is connected to pipe network tune flow control device and pressurization pump group
Between, or be connected directly between municipal network water supply and pressurization pump group, specific effect is to stablize municipal tap water water flow, when interior
When circulating non-negative pressure stabilized compensating tank carries out intelligent compensation, the fortune that air-water mixture influence water pump assembly is generated in tank is avoided
Row is stablized, and the generation of negative pressure is avoided, and prevents from generating remaining water reduction secondary pollution in tank.
Municipal water flows into the water inlet pipe 5 of the non-negative pressure stabilized compensating tank of internal-circulation type, the municipal water with certain pressure from into
The water outlet 8 of water pipe 5 sprays vertically upward, and rushes at the upper wall of tank body 1, and in the process, the impulse force of water is by the weight of its own
Power offsets a part, so that the hydraulic pressure for rushing at 1 upper wall of tank body is suitable, it may be assumed that the water for rushing at 1 upper wall of tank body will not be back towards
It is impacted to 1 lower wall of tank body, the suitable hydraulic pressure for reaching 1 upper wall of tank body is had enough kinetic energy by the blocking of 1 upper wall of tank body again
Dispersion flows to four walls of tank body 1 around, so that 1 bottom of arrival tank body of the four walls smoothness along tank body 1, enables water level
Slowly go up, the bottom of tank body 1 has outlet pipe 6, and water is smoothly flowed out from the outlet of outlet pipe 6 27, this water inlet, the side being discharged
Formula is milder, prevents the generation of the excessive air-water mixture caused by excessive into water impulse force.Water inlet pipe 5 and outlet pipe 6 are each provided at tank
The bottom of body 1, convenient for the installation of pipeline, but also being not likely to produce stagnant water remaining water in tank body 1.
The non-negative pressure stabilized compensating tank of internal-circulation type further includes having vacuum suppresser 4, specific to act on are as follows: to pass through mechanical structure
It realizes and is automatically closed or opens to what gas in tank body 1 circulated.Water level in the non-negative pressure stabilized compensating tank of internal-circulation type is lower
When, floating ball 24 is in the bottom of interior cover 11 by gravity, floating ball 24 far from the sealing ring 16 in interior 11 top of cover, this
When, air and outside air in tank body 1 penetrate through.When tank body 1 starts to intake, water level is gradually increasing, and water level is not to floating ball
When 24 generation buoyancy, the air in tank body 1 enters first chamber 23 by the stomata 20 of lower cover 14, and by upper cover body 13
Through-hole 18 reaches the second chamber 26 of vacuum suppresser 4, is finally discharged from exhaust pipe 27.When water level rises until holding up floating ball 24
And when floating ball 24 being made to reach 16 position of sealing ring of upper cover body 13, if hydraulic pressure is greater than 0.02MPa in tank body 1, sealing ring can be made
16 centre bore 19 forms reliable sealing；When the inflow of tank body 1 is less than water yield, water level decreasing, then floating ball 24 falls, outside
Boundary's air enters in tank body 1 through exhaust pipe 27, second chamber 26, through-hole 18, air-filtering membrane 17, first chamber 23, stomata 20,
Into tank body 1, make-up gas avoids the occurrence of vacuum.
Air-filtering membrane 17 is filtered purification to the air for entering tank body 1, guarantees water quality not by secondary pollution.
