Abstract
The utility model provides a negative-pressure-free water supply device with overpressure protection belonging to the two times pressure water supply device field. The device comprises a stable flow compensator, a vacuum suppressor, a pump, a control cabinet, a pressure control meter and an overpressure protection device. The stable flow compensator inlet pipe is directly connected with outdoor city pipe net. Said pressure control meter and overpressure protection device are arranged on the pump outlet mother pipe. The overpressure protection device can be a pressure control device or a pressure relief device. When a pressure relief valve is arranged, an automatic control valve needs to be arranged before the valve. The utility model has the advantages of safe and reliable water supplying when system overpressure water supply is present, energy saving, cost saving, water saving and environmentally friendly. The negative-pressure-free water supply device with overpressure protection is mainly used for second pressure water supply when outdoor city pipe net has high pressure or system water supply height is rather huge.
Description
1, technical field
The utility model relates to a kind of secondary pressurizing feedwater equipment, specifically a kind of no-negative-pressure water supply equipment of installing overpressure protection.
2, background technology
No-negative-pressure water supply equipment adopts the pressure controller table of water exit end to come the operation of control of pump, water pump adopts frequency converter to realize automatic speed regulation control, when the frequency converter of no-negative-pressure water supply equipment control usefulness or pressure controller table break down or damage, water pump will constant-speed operation, water pump adopts centrifugal water pump again, and when water supply volume hour, pump head is too high, may cause the damage of pipeline, watering equipment and annex thereof, with entail dangers to people's property and personal safety; No-negative-pressure water supply equipment directly is connected in series with outdoor city planting ductwork again, and outdoor pipe network water pressure fluctuation also will cause the superpressure situation of equipment outlet.
3, utility model content
The purpose of the present utility model provides the no-negative-pressure water supply equipment that a kind of water supply security is installed overpressure protection reliably.
The technical scheme that its technical problem that solves the utility model adopts is: the no-negative-pressure water supply equipment of installing overpressure protection; be by steady flow compensator; vacuum suppresser; water pump; switch board; the pressure controller table; compositions such as overpressure protection apparatus; the steady flow compensator water inlet pipe directly is connected in series with outdoor city planting ductwork; be equiped with pressure controller table and overpressure protection apparatus on the water pump water outlet house steward; current are after water inlet pipe enters steady flow compensator; add by water pump and to press to watering equipment or utensil and supply water; when frequency converter in the switch board or pressure controller table break down or damage; water pump will transfer constant-speed operation to; if the water supply volume of system is less or not during water; the lift of water pump constant-speed operation raises; when the pressure of outfall sewer surpasses the maximum pressure of default; the overpressure protection apparatus action; water pump state out of service; system pressure descends; avoided pipeline; watering equipment and annex thereof damage or explosion because of pressure-bearing is too high; water pump resumes operation automatically after system overpressure is eliminated; so both guaranteed water supply security, and can guarantee again can recover normal operation after superpressure is eliminated.Overpressure protection apparatus can be pressure controller or relief valve device, when the installing relief valve autocontrol valve should be set before valve.
4, description of drawings
Among the figure, 1, steady flow compensator, 2, vacuum suppresser, 3, water pump, 4, switch board, 5, the pressure controller table, 6, overpressure protection apparatus, 7, water inlet pipe, 8, outfall sewer, 9, watering equipment or utensil.
5, the specific embodiment
Explain below doing with regard to the no-negative-pressure water supply equipment of 1 pair of installing overpressure protection of the present utility model of accompanying drawing below.
As shown in Figure 1; the no-negative-pressure water supply equipment of installing overpressure protection of the present utility model; be by steady flow compensator (1); vacuum suppresser (2); water pump (3); switch board (4); pressure controller table (5); overpressure protection apparatus; (6) composition such as; steady flow compensator (1) water inlet pipe (7) directly is connected in series with outdoor city planting ductwork; be equiped with pressure controller table (5) and overpressure protection apparatus (6) on water pump (3) outfall sewer (8); current are after water inlet pipe (7) enters steady flow compensator (1); add by water pump (3) and to press to watering equipment or utensil (9) and supply water; when frequency converter in the switch board (4) or pressure controller table (5) break down or damage; water pump (3) will transfer constant-speed operation to; if the water supply volume of system is less or not during water; the lift of water pump (3) constant-speed operation raises; when the pressure of outfall sewer (8) surpasses the maximum pressure of default; overpressure protection apparatus (6) action; water pump (3) state out of service; system pressure descends; avoided pipeline; watering equipment or utensil (9) and annex thereof damage or explosion because of pressure-bearing is too high, and water pump (3) resumes operation automatically after system overpressure is eliminated.Overpressure protection apparatus (6) can be pressure controller or relief valve device, when the installing relief valve autocontrol valve should be set before valve.
The utility model is owing to install overpressure protection apparatus on the no-negative-pressure water supply equipment outfall sewer; can play the safeguard protection effect to the superpressure operation of equipment; so the no-negative-pressure water supply equipment of installing overpressure protection of the present utility model has system overpressure safe and reliable when supplying water, can bring into play the advantage functions such as energy-conservation, joint money, water saving, hygienic environment-protecting of no-negative-pressure water supply equipment again.
Claims (2)
1, the no-negative-pressure water supply equipment of installing overpressure protection; form by steady flow compensator, vacuum suppresser, water pump, switch board, pressure controller table, overpressure protection apparatus etc.; it is characterized in that: the steady flow compensator water inlet pipe directly is connected in series with outdoor city planting ductwork, is equiped with pressure controller table and overpressure protection apparatus on the water pump water outlet house steward.
2, the no-negative-pressure water supply equipment of installing overpressure protection according to claim 1 is characterized in that: overpressure protection apparatus can be pressure controller or relief valve device, when the installing relief valve autocontrol valve should be set before valve.
