Abstract
The invention provides a constant-pressure water supply device and aims to overcome the defects that when instant large-flow water use occurs at a water use terminal in a system with long or thin pipelines, water pressure signals fed back to a controller is evidently delayed, pressure fluctuation is generated, frequent on and off of a water-supply water pump in a short time occurs and the problems cannot be solved by a capsule type air pressure tank of a conventional water supply system. According to the technical scheme, a cavity with pressure stabilizing and water storing functions is designed, the cavity is communicated with a water supply pipe network and the water use terminal through a water inlet and a water outlet respectively, a check valve is arranged between the water inlet and the water supply pipe network, and the water in the pressure-stabilizing cavity can keep constant pressure through a counterweight structure. When the instant water use occurs at the water use terminal, stable-pressure water supply can be achieved by the cavity while severe fluctuation of the pressure at the water inlet end can be avoided by the cavity, and the pressure fluctuation of the water supply pipe network is eliminated.
Description
Technical field
The present invention relates to one way of life water supply installation, particularly relate to a kind of device that can keep constant pressure water supply under instantaneous large discharge situation.
Background technology
Current secondary living water is generally constant pressure water supply, regulates water pump operation frequency to reach the function of constant water pressure by the intrasystem pressure change of testing pipes.But, in actual use, still there is no small defect in this type systematic, especially in the system that pipeline is longer or thinner, water pump carrys out stable water supply hydraulic pressure by opening or increasing frequency process, when occurring instantaneous large discharge water with water end, hydraulic signal feeds back to controller and there will be obvious time delay, when can produce instantaneous large discharge water, initial pressure is enough, but the phenomenon of insufficient pressure after the short time, this class negative feedback control pattern can because inevitable control hysteresis brings pressure oscillation problem in addition, especially when comparatively thin pipe end water, the direct-connected flushing valve in washroom as common commercial building, when it is used, switch frequent by the interior in short-term start and stop state producing the fluctuation of obvious ductwork pressure and water supply pump.In similar water system, part place is for solving this problem, most employing capsule-type air pressure tank regulates ductwork pressure, the pressure oscillation as far as possible avoiding instantaneous water to cause and the frequent start-stop of water pump, but by practical operation situation, effect is unsatisfactory, by the restriction of installation site, cannot take into account useful water spot, the regulating pondage of air pressure tank own is limited in addition, and practical adjustments effect is general.
Summary of the invention
The present invention is for solving the problems referred to above that at present conventional secondary domestic water supplying system produces when instantaneous water and the one water supply servicing unit designed, be installed on and use water end, realized the function of the pressure-stabilizing water supply when instantaneous water by the water yield of device itself and hydraulic pressure regulating power.Reduce the pressure oscillation that produces when instantaneous water use variation is larger of system thus, and the start and stop frequency of water pump under reducing this situation, carry out the application life of protection system, raising water pump and equipment.
The technical scheme that the present invention takes is: design the cavity that has voltage stabilizing water storage function, this cavity is connected respectively by water inlet, delivery port and waterline network and with water end, and between water inlet and waterline network, flap valve is set, gravity structure design simultaneously by appraising and deciding makes the water in voltage stabilizing cavity can maintain a constant pressure, this pressure can be regulated by counterweight, and the pressure that counterweight produces under normal circumstances should lower than normal water supply pressure.When there is instantaneous water with water end (W.E.), this cavity maintains water inlet end pressure and big ups and downs does not occur while realizing steady pressure water supply, thus realizes the object eliminating waterline network pressure oscillation.

Detailed description of the invention
Below the working condition of this device is described, in Fig. 1, during device work, the water of water supply network enters cavity (4) by water inlet (1), when the use water end (W.E.) of delivery port (8) UNICOM is without water, the pressure produced water by top board (6) because of balance weight body (7) is lower than pressure of supply water, now water level can rise, until top board reaches upper limit (5) place, when delivery port (8) UNICOM start to use water with water end (W.E.) time, cavity (4) interior water level can start to decline, but the pressure produced due to balance weight body (7) is a steady state value, so cavity (4) interior hydraulic pressure can maintain this pressure and continue to supply water to delivery port (8), until top board (6) drops to lower limit (3) place.The water retention capacity that this device provides thus makes full use of and pressure-stabilizing water supply.Because the effect top board (6) of intake pressure can rise to upper limit (5) place again after with water, make to be full of water in cavity (4) for subsequent use.With timer water inlet (1) place install flap valve (2) cavity (4) can be guaranteed even if retaining complete after front end water supply network lack of water cause pressure to reduce, this device can realize normal water supply equally.
Above-described embodiment, only for design of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement accordingly, can not limit protection scope of the present invention with this.All do according to principle of the present invention and Spirit Essence any amendment, equivalently to replace and improvement etc., within all should being encompassed in scope.
Claims (2)
1. a constant pressure water supply equipment, is made up of water inlet, flap valve, cavity, lower limit, upper limit, top board, balance weight body, delivery port, it is characterized in that, top board can upper limit in cavity and sliding between lower limit.
2. a kind of constant pressure water supply equipment according to claim 1, is characterized in that, balance weight body weight is adjustable and it is less than the operating pressure of water in waterline network to the pressure that water in cavity produces.
