Technical field
The utility model relates to a kind of tap water pipe network water supply installation, particularly relates to a kind of water supply control apparatus of bringing in water pressure control that has.
Background technique
In the prior art, water supply in the city is divided into once supplies water and two difference of secondary water-supply water system independently, in traditional secondary water supply system, generally adopt and build the pond or water tank is set, directly absorbing water from pond or water tank by water pump is transported to the user, this kind way of supplying water, water inlet in the water tank is can be unrestricted, but when pond or water tank water intake, can the pressure of upper end pipe network be impacted, when serious, even also can have influence on user's normal water supply on every side.
In the prior art, second pressure water supply equipment---pipe network Pressure-superposed water supply equipment is compared with above-mentioned secondary water supply system, because it does not have secondary pollution, is approved by people gradually, is widely used gradually then; Pipe network Pressure-superposed water supply equipment on the market adopts pot type not have negative pressure or box no negative pressure supercharging equipment more, come the no negative pressure of water device can not adapt to the pressure transient change of bringing because of water intaking rapidly but lack reliable control municipal administration, can not effectively ensure and bring in water pressure.
The model utility content
In view of this, the utility model proposes a kind of water supply control apparatus of bringing in water pressure control that has, pass through the technical program, assurance can directly be connected with city planting ductwork, can take full advantage of the original pressure of city planting ductwork, and bring in water pressure on guaranteeing and be not less than setting value, user's pressure of supply water satisfies the mutatis mutandis requirement of city planting ductwork around safeguarding.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of water supply control apparatus of bringing in water pressure control that has, include control cabinet, pressure transmitter and pressure transducer, also include main valve, leading pipe, described main valve is by valve body, last flap, lower Disc, valve rod and valve pocket constitute, described valve body is provided with intake pipe and outlet pipe, the intersection of intake pipe and outlet pipe is provided with by mouth, the described flap of going up is arranged in the valve pocket, the upper end of valve rod is fixed on the flap, described lower Disc is fixed on the lower end of valve rod, lower Disc is pressed on mouth, described leading pipe is two, one end of two leading pipes is connected with valve pocket respectively, the other end of two leading pipes is separately positioned in the intake pipe and outlet pipe of valve body, and described pressure transducer is arranged in the intake pipe, is electrically connected mutually through pressure transmitter and control circuit in the control cabinet.
The valve body that is positioned at the valve pocket below is provided with seal ring, and described valve rod upper end is set with spring on the described valve rod in seal ring extend into valve pocket, and the lower end of described spring is pressed on down valve and debates, and the upper end of spring is pressed on the valve interior wall.
The leading pipe that at one end is arranged in the outlet pipe is provided with mortor operated valve, and described mortor operated valve is electrically connected mutually by lead and control circuit in the control cabinet.
The valve body that is positioned at above the valve pocket is provided with discharge opening, and discharge opening is provided with capping.
Beneficial effect after the employing technique scheme is: a kind of water supply control apparatus of bringing in water pressure control that has, can directly be connected with city planting ductwork, make the secondary pressurized equipment can take full advantage of the original pressure of city planting ductwork, reduce operating cost, and bring in water pressure on can realizing ensureing, have the mutatis mutandis requirement of comprehensively satisfying city planting ductwork, safeguard city planting ductwork safety and stable, on bring in water pressure safe guarantee arranged.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model working state structure schematic representation.
Among the figure, flap, 8 lower Discs, 9 valve rods, 10 valve pockets, 11 intake pipes, 12 outlet pipes on 1 control cabinet, 2 pressure transmitters, 3 pressure transducers, 4 main valves, 5 leading pipes, 6 valve bodies, 7,13 by mouth, 14 seal rings, 15 springs, 16 mortor operated valves, 17 discharge openings, 18 cappings.
Embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the water supply control apparatus that water pressure is controlled is brought in having that the utility model relates to, include control cabinet 1, pressure transmitter 2 and pressure transducer 3, also include main valve 4, leading pipe 5, described main valve 4 is by valve body 6, last flap 7, lower Disc 8, valve rod 9 and valve pocket 10 constitute, described valve body 6 is provided with intake pipe 11 and outlet pipe 12, the intersection of intake pipe 11 and outlet pipe 12 is provided with by mouth 13, the described flap 7 of going up is arranged in the valve pocket 10, the upper end of valve rod 9 is fixed on the flap 7, described lower Disc 8 is fixed on the lower end of valve rod 9, lower Disc 8 is pressed on mouth 13, described leading pipe 5 is two, one end of two leading pipes 5 is connected with valve pocket 10 respectively, the other end of two leading pipes 5 is separately positioned in the intake pipe 11 and outlet pipe 12 of valve body 6, and described pressure transducer 3 is arranged in the intake pipe 11, is electrically connected mutually through pressure transmitter 2 and control circuit in the control cabinet 1.
The valve body 6 that is positioned at valve pocket 10 belows is provided with seal ring 14, described valve rod 9 upper ends are in seal ring 14 extend into valve pocket 10, be set with spring 15 on the described valve rod 9, the lower end of described spring 15 is pressed on down valve and debates on 8, and the upper end of spring 15 is pressed on valve body 6 inwalls.
The leading pipes 5 that at one end are arranged in the outlet pipe 12 are provided with mortor operated valve 16, and described mortor operated valve 16 is electrically connected mutually by lead and control cabinet 1 interior control circuit.
The valve body 6 that is positioned at above the valve pocket 10 is provided with discharge opening 17, and discharge opening 17 is provided with capping 18.
The utility model is when work, when pressure transmitter 2 detects when bringing in water pressure near setting pressure, signal is passed to control circuit in the control cabinet 1, slowly close under the effect of mortor operated valve 16 control circuit in control cabinet 1, thereby reduce the cross-section area of leading pipe 5, reduce the water-outlet quantity of valve pocket 10 in the valve body 6, thereby cause valve pocket 10 internal pressures of valve body 6 to rise, and the down pressure of flap 7 is increased, connecting lower Disc 8 by valve rod 9 moves downwards, reduced the open degree of main valve 4, thereby reduced from the water withdrawal of upper end pipe network, to ensure the pressure of upper end pipe network; When pressure transmitter 2 detects when bringing in water pressure and being higher than setting pressure, signal is passed to control cabinet 1, control cabinet 1 control mortor operated valve 16 is slowly opened, increase the cross-section area of leading pipe 5, increase the water-outlet quantity of valve pocket 10 in the valve body 6, cause valve pocket 10 pressure of valve body 6 to descend, the down pressure that is applied to flap 7 reduces, connect upwards action of lower Disc 8 by valve rod 9, increased the open degree of valve, thereby increased from the municipal water withdrawal.
