Abstract
The invention discloses a non-negative pressure water supply facility. The non-negative pressure water supply facility comprises a water storage tank which is connected with a municipal water supply pipe network; a water inlet pressure sensor is arranged at a water outlet of the water storage tank; the water storage tank is connected with a booster pump unit in series; the booster pump unit is connected with a steady flow compensation tank in series; a water outlet pipe of the steady flow compensation tank is provided with a water outlet pressure sensor; and the steady flow compensation tank is connected with a water outlet pipe at the tail end of the pipe network. Compared with the prior art, the non-negative pressure water supply facility can solve the problems of great pressure variation and low capacity of adjusting water yield existing in the traditional pneumatic water supply facility.
Description
Technical field
The present invention relates to supply equipment, especially a kind of water supply network internal pressure that makes changes little supply equipment.
Background technology
After the pressurization of pressure pump group, the airtight auto-pneumatic cylinder of connecting is connected to the pipe network end and supplies water existing pneumatic installation water supply to terminal temperature difference through municipal network water supply reservoir or water tank, and auto-pneumatic cylinder is driven by stabilized pressure pump.Pneumatic installation water supply utilizes the compressed air in the airtight auto-pneumatic cylinder, and the water in the jar is delivered to the pipe network end, and its effect is equivalent to water tower or high level cistern, and can regulate and store certain water yield and keep required pressure, be to use the equipment that boosts comparatively widely.Because the pressure of supply water of pneumatic installation water supply is kept by the jar compressed air, so the setting height(from bottom) of tank body can be unrestricted, thereby should not be arranged on the place of water tower and high level cistern.The advantage of this equipment is a small investment, and construction speed is fast, removes easily, and it is flexible that the place is set, and maintenance management is easy, and water quality is not vulnerable to secondary pollution, has certain elimination water hammering.Its shortcoming is that the tank body moisture storage capacity is limited, and water yield regulating power is little, and operating cost is high; In addition, because auto-pneumatic cylinder is connected in the pipe network, the pressure in jar changes with the pipe network internal pressure and is positive change, and the compression wave of whole pipe network is not had any pressure stabilization function, is not suitable for the water supply of residential building.
Summary of the invention
Problem to be solved by this invention provides a kind of non-negative pressure water-supply installation, changes little with water yield regulating power greatly problem to solve existing pneumatic installation water supply pipe network internal pressure.
In order to address the above problem; Technical scheme of the present invention is: this non-negative pressure water-supply installation includes the water tank that connects municipal network water supply; The delivery port of said water tank is provided with the intake pressure sensor, and said water tank is in series with the pressure pump group, and said pressure pump group is in series with the current stabilization compensating tank; The outlet pipe of said current stabilization compensating tank is provided with the discharge pressure sensor, and said current stabilization compensating tank connects the terminal outlet pipe of pipe network.
In the technique scheme, more concrete scheme can be: said current stabilization compensating tank comprises the tank body that is connected with water inlet pipe and outlet pipe, is provided with air bag in the said tank body, and said air bag is connected with air inlet pipe, compressed air suits in the said air bag; Said air bag is provided with automatic air valve and gas pressure sensor.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
This non-negative pressure water-supply installation has utilized and can when ductwork pressure is excessive, also reduce ductwork pressure simultaneously to setting value by water storage; When ductwork pressure is too small,, the pipe network terminal temperature difference also increases the current stabilization compensating tank of ductwork pressure to setting value simultaneously for supplying water; Play the pressure that reduces in the pipe network and change, and the effect that increases the water yield regulating power of whole supply equipment; And air bag also has separation gas to contact with water, the effect of avoiding water quality to be polluted.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the front view of current stabilization compensating tank in the embodiment of the invention.
The specific embodiment
Implement the present invention is made further detailed description below in conjunction with accompanying drawing:
Non-negative pressure water-supply installation shown in Figure 1 includes the water tank 1 that connects municipal network water supply; The delivery port of this water tank 1 is provided with intake pressure sensor 2; Water tank 1 is in series with pressure pump group 3; Pressure pump group 3 is in series with current stabilization compensating tank 4, and the outlet pipe of current stabilization compensating tank 4 is provided with discharge pressure sensor 5, and current stabilization compensating tank 4 connects the terminal outlet pipe 6 of pipe network.Intake pressure sensor 2 is controlled by the electrical control cubicles 7 of control system with pressure pump group 3 and discharge pressure sensor 5.The water inlet of current stabilization compensating tank shown in Figure 2 and delivery port are arranged on the bottom of tank body 11, and the water inlet of tank body 11 is connected with water inlet pipe 12, and the delivery port of tank body 11 is connected with outlet pipe 13.Top in the tank body 11 is provided with air bag 14, compressed air suits in the air bag 14, and to strengthen the pressure regulatory function, air bag 14 is connected with air inlet pipe 15, and air inlet pipe 15 connects feeder; Air bag 14 also is connected with automatic air valve 16 and gas pressure sensor 17, and gas pressure sensor 17 is connected to air supply system.
The control system is earlier to Inlet and outlet water pressure preset setting values, and during use, the control system starts or stops pressure pump group 3 according to the pressure information of intake pressure sensor 2 feedbacks, supplies water to the terminal outlet pipe 6 of water supply network through current stabilization compensating tank 4; When the intake pressure in the pipe network was excessive, tap water flowed into current stabilization compensating tank 4, and the gases in the air bag 14 of current stabilization compensating tank 4 are discharged through automatic air valve 16, and current stabilization compensating tank 4 is in the retaining state, and the intake pressure in this moment pipe network reduces and near setting value; When the control system detects the pipe network internal pressure when too small; The control system starts air bag 14 air feed of feeder to current stabilization compensating tank 4, and the force value in the air bag 14 is discharged tap water during greater than the force value in the pipe network in current stabilization compensating tank 4; Supply water to the terminal outlet pipe 6 of pipe network; When the control system detects force value in the air bag 14 that gas pressure sensor 17 feeds back to and reaches setting value, stop air feed, the pressure in this moment pipe network increases near setting value.Like this, current stabilization compensating tank 4 water storages and reduce the pipe network internal pressure when pipe network internal pressure is excessive, current stabilization compensating tank 4 discharged water and increases the pipe network internal pressure when pipe network internal pressure was too small, and the pipe network internal pressure of this non-negative pressure water-supply installation changes and reduces, and water yield regulating power is stronger.
