Description
Technical field
The utility model belongs to space heating water system apparatus structure technical field.
Background technology
Existing space heating water system comprises solar water supply device, Teat pump boiler hot-water supply, and electric boiler or gas fired-boiler hot-water supply.Because relations such as the volume and weight of boiler and maintenance maintenance safety, operated by rotary motion are other or place in the basement of building at building.This set can't directly obtain hot water when the water intaking leading position is higher than the boiler position, the way that adopts at this situation has two kinds at present: a kind of is to adopt bearing type water tank, utilize cold water to press hot water, make the user can go out hot water once turning on the tap, this bearing type water tank cost height, potential safety hazard are big, and the building developer dares to adopt less; Second kind of way is to install the pressure that a cover constant pressure water supply equipment guarantees to have at any time in the pipeline setting additional with non-press-bearing water tank, make the user also can obtain hot water once turning on the tap, and constant pressure water supply equipment price is very high, and its cost is too high.
Summary of the invention
The purpose of this utility model provides a kind of constant pressure water supply equipment that can not adopt for the weak point that overcomes above-mentioned prior art existence just, cost is extremely low, and the user can go out the water supply installation of the alternative constant pressure water supply equipment of hot water once turning on the tap.
The purpose of this utility model is achieved by the following technical solution.A kind of water supply installation of alternative frequency-changing pressure stabilizing equipment relates to the water supply installation of the high-order water outlet of a kind of lower water box, and circulating line of being made up of boiler, cold water feed pipe, hot water feeding pipe and return pipe and the depotition cock that is arranged on the circulating line are formed,,
Hot water feeding pipe road between boiler and the depotition cock is provided with pipe pressurizing pump, magnetic valve, cold water pipe check-valves, hot-water line check-valves and cold water feed pipe, and its connected mode is, booster pump is connected on the hot water feeding pipe by the depotition cock end; The hot-water line check-valves leans on into boiler, and the cold water feed pipe is connected on the hot water feeding pipe between hot-water line check-valves and the pipe pressurizing pump, and cold water pipe check-valves, magnetic valve are connected the cold water feed pipe.
Depotition cock is provided with a magnetic valve and is provided with a controller with return pipe between the boiler and is connected with the pipe pressurizing pump with magnetic valve respectively.
Pipe pressurizing pump of the present utility model is the pipe pressurizing pump of band flow switch.
Because the pipe pressurizing pump that is arranged on the hot water feeding pipe has flow switch, after depotition cock is opened, the interior cold water of cold water pipe this moment begins to enter the hot water feeding pipe, the magnetic valve that connects is in normally open, the pipeline booster pump of flowing through, in case current process, the pipe pressurizing pump brings into operation, and extract cold water in the cold water pipe and the hot water in the boiler simultaneously, this moment, controller instructed the magnetic valve of cutting out on the cold water pipe to stop cold water at once, and under the operation of pipe pressurizing pump, will only extract the hot water in the boiler this moment, like this, the hot water in the boiler sends the depotition cock place by the hot water feeding pipe in streams to a place through the pipe pressurizing pump.
After the user closes depotition cock, the anhydrous stream process of pipe pressurizing pump, the requirement that flow switch is set according to controller is closed, and makes the pipe pressurizing pump out of service, and the cold water pipe of controller instruction simultaneously magnetic valve is opened, and whole water supply installation is returned to original state.
The magnetic valve that is arranged on the water return pipeline is just opened when being used for the whole water supply installation pipeline loop of circulation heating, and the magnetic valve on this moment cold water pipe cuts out simultaneously, and the user can open depotition cock at any time and obtain hot water in this state.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is the utility model apparatus structure connection diagram.
The specific embodiment
The utility model device adopts the non-press-bearing water tank 1 of taking pore or manhole out of, cold water feed pipe 2, hot water feeding pipe 3 and return pipe 11 are connected form one closed-loop path, water tank two ends, depotition cock is arranged on this loop, during installation, on one section hot water feeding pipe 3 between water tank 1 and the depotition cock, be separately installed with hot water feeding pipe's check-valves 7, cold water feed pipe 2 and pipeline press pump 4, install on the cold water feed pipe 2 and be connected with magnetic valve 5 and cold water pipe check-valves 6, and check-valves 6,7 are the control valve of control one-way flow, it in the pipe pressurizing pump 4 product of band flow switch, in fact before flow switch also can be arranged on pipe pressurizing pump 4 separately, principle is identical, and cold water feed pipe 2 is communicated with the running water pipe network.Between the return pipe between depotition cock 9 and the water tank 11, be provided with a magnetic valve 8 and be used to heat the whole circulation pipeline.In order to control magnetic valve 5,8 and the open and close of pipe pressurizing pump 4, be provided with a controller 10 and magnetic valve 5 specially, 8 and pipe pressurizing pump 4 connect respectively, the control procedure of controller is very simple, magnetic valve 5 is in normally open, magnetic valve 8 is in normally off, have only when the user opens depotition cock 9, controller 10 almost is being to cut out magnetic valve 5 under with the interior time difference in 1 second, and flowing cold water has made the flow switch in the pipe pressurizing pump 4 start the pipe pressurizing pump, and the hot water in the effect lower hot water tank 1 of pipe pressurizing pump is taken out continuously toward depotition cock 9.In case and the user has closed depotition cock 9, thereby flow switch has stopped the operation of pipe pressurizing pump 4 according to the designing requirement of controller 10, this moment magnetic valve 5 by controller opens, make the whole system device be returned to original original state.Magnetic valve 8 is only opened by controller 10 when pipeline loop is recycled heating, will close magnetic valve 5 simultaneously, and can at any time open depotition cock and obtain hot water as long as the user needs this moment.
