Fig. 2 is the sectional view of the vacuum suppresser of the supply equipment that has a prepressing type vacuum suppresser of the present utility model.
[specific embodiment]
See also Figure 1 and Figure 2, the utility model is a kind of supply equipment that has the prepressing type vacuum suppresser, it comprises prepressing type vacuum suppresser 1, intake pressure sensor 2, water inlet pipe 3, compensating tank 4, electric control box 5, discharge pressure sensor 6, low discharge pressurize pipe 7 and water pump assembly 8.Wherein, described intake pressure sensor 2 is mounted on the compensating tank 4, is used to detect the hydraulic pressure in the compensating tank 4.Described water pump assembly 8 has an export pipeline 81 and an entrance pipe 82; Described low discharge pressurize pipe 7 is connected with the export pipeline 81 of water pump assembly 8, and this low discharge pressurize pipe 7 is connected with compensating tank 4.Water inlet is mended in the compensating tank 4 when hydraulic pressure is high in the water inlet pipe 3, the water storage in the compensating tank 4 is replenished in the entrance pipe 82 of water pump assembly 8 during the low or zero-pressure of hydraulic pressure in water inlet pipe 3.Described vacuum suppresser 1, intake pressure sensor 2, discharge pressure sensor 2 and water pump assembly 8 electrically connect with electric control box 5, and this electric control box 5 can be controlled the work of vacuum suppresser 1, intake pressure sensor 2, discharge pressure sensor 2 and water pump assembly 8.
The maximum improvement of the supply equipment part that has the prepressing type vacuum suppresser of the present utility model is: be provided with the vacuum suppresser 1 that is filled with Compressed Gas in advance in the top of described compensating tank 4.This vacuum suppresser 1 comprises an atmospheric pressure cavity 11 and is installed on upper cover 12 on the atmospheric pressure cavity, forms first host cavity 13 between described atmospheric pressure cavity 11 and the upper cover 12, forms second host cavities 14 in the described atmospheric pressure cavity 11.This first host cavity 13 is equipped with valve 110, pressure meter 111 and pressure detector 112 for there not being the chamber of pressure in it.This second host cavity 14 is for there being the pressure chamber, and a kind of nontoxic, Compressed Gas of being difficult for molten water of preliminary filling further is provided with the wireway 141 that is connected with compensating tank 4 and the gas control valve 142 of control wireway 141 switches in it.Described atmospheric pressure cavity 11 lower ends are provided with one described vacuum suppresser 1 are mounted to flange end cap 15 on the compensating tank 4, further are provided for increasing the radial direction seal ring 16 and the end face seal pad 17 of second host cavity, 14 sealings between flange end cap 15 and atmospheric pressure cavity 11.Flange end cap 15 and atmospheric pressure cavity 11 are by fastening sealing of bolt (not label), and flange end cap 15 goes back and compensating tank 4 welds together.
The operating principle of the supply equipment that has a prepressing type vacuum suppresser of the present utility model is as follows: when producing vacuum in the compensating tank 4, be connected with compensating tank 4 by gas control valve 142 and wireway 141, and the Compressed Gas nontoxic, that be difficult for molten water in second host cavity 14 are mended the body of going into to calm the anger by wireway 10, to realize the current stabilization compensation.Have the body of calming the anger to get back in second host cavity 14 of atmospheric pressure cavity 11 when compensating tank 4 internal pressures raise, make in the compensating tank 4 and hold full water, in order to next water use peak, at this moment gas control valve 142 cuts out automatically, and water can not enter in second host cavity 14 of atmospheric pressure cavity 5.Because wireway 10 stretches in the compensating tank 4, compensating tank 4 upper entrance places leave the gas of small amount of compression, the water that can guarantee compensating tank 4 does not blow back in the vacuum suppresser 1, because compensating tank 4 is communicated with therefore all right pressure-stabilizing water supply with user's pipe network by low discharge pressurize pipe 7.
