Abstract

The utility model discloses an activating, circulating, and constant pressure water supplying device for water tanks of a high buildings, which is composed of an electric in-line pump, a check valve, a safety valve, a pressure gauge, a one-way regulating valve, a nozzle with micropores connected with da circulating pipe, a flow return pipe, and an emergency check valve. Via increasing water pressure to a user's pipe network, when the water pressure exceed a set value, the safety valve is pushed aside, the over-pressure water quantity flows back into a water outlet pipe of a water basin; when the water pressure is insufficient, the safety valve can go back to the originally set position, and water pressure of the water supply network can be kept constant. The pressurized circulating water can be jetted from a pipe with micropores, and the whole water basin can be in a good circulating state; the water quality of the secondary supplied water can be improved.

Description

Pond of high building activation cycle constant pressure water-supply device

The utility model relates to storage cistern secondary water-supply device.

Known storage cistern all adopts the atmosphere self-pressing type to supply water, the defective of this method maximum is to be in not enough state when the hydraulic pressure of the peak water phase pipe network especially hydraulic pressure of attic, to can not show a candle to direct-furnish water quality good for the water quality of storage cistern in addition, be commonly called as stagnant water, directly influence the healthy of user's normal water and user.

The purpose of this utility model provides a kind of normal hydraulic pressure of user that can guarantee and can obtain the storage cistern secondary water-supply device of drink water again.

The technical solution of the utility model is as follows: a kind of pond of high building activation cycle constant pressure water-supply device, and by tubing pump (1), flap valve (2), spring loaded safety valve (3), circulation pipe (4), pressure meter (5), unidirectional control valve (6), return duct (7), emergent flap valve (8) and micro porous spray tube (11), form.The water inlet of tubing pump (1) is connected with the outlet pipe (9) of storage cistern, the delivery port of tubing pump (1) is connected with flap valve (2), other end string dress safety valve (3) back of flap valve (2) connects with feed pipe 10 nets, unidirectional circulation control valve (8) one end strings dress pressure meters (5) back is connected with water supply network 10, the other end is communicated with circulation pipe (4) and storage cistern (12), micro porous spray tube (11) is connected circulation pipe (4) and is placed in the interior water of storage cistern (12), emergent flap valve (8) one ends are connected the other end with the outlet pipe (9) of storage cistern and are connected with water supply network (10), return duct (7) two ends are connected with storage cistern outlet pipe (9) with safety valve (3) respectively, setting and the installation and known being as good as of ventilative bleed off pipe (14) of the Chi Gai (13) of storage cistern (12) and filling pipe (15).

Operating principle of the present utility model is as follows: the electronic tubing pump pressurization back, water footpath of storage cistern (12) directly enters water supply network (10) by flap valve (2) through safety valve (3), when the hydraulic pressure of pipe network (10) surpasses setting value, safety valve (3) will be backed down, the water yield of superpressure is in return duct (7) is back to pond outlet pipe (9), when water phase hydraulic pressure in peak is not enough, the effect that the spring of safety valve (3) is reduced pressure and return back to desired location gradually, thereby guaranteed the constant pressure water supply of pipe network (10).If when meeting power failure or device fails, the emergent flap valve (8) that connects storage cistern outlet pipe (9) and water supply network (10) will be opened automatically, make the user continue to obtain water.Unidirectional control valve (6) is transferred to suitable open degree, the water of pipe network (10) is after pressurization, spray through the jet pipe that circulation pipe (4) connects in placing storage cistern by unidirectional control valve (6), make whole Chi Shui form the countless bubble globules, water is become dynamically by static state, and the moisture subchain can't condense and enlarge.

The utility model has the advantages that: under the situation of normal power supply, the user can obtain constant pressure water supply can obtain the active drinking water of high-quality fresh again.

Below in conjunction with the description of the drawings and embodiment, the utility model will be further described.

Fig. 1 is a structural representation of the present utility model.

Embodiment:

The permanent happy waterworks of a kind of pond of high building activation cycle are made up of electronic tubing pump 1. flap valve 2. spring loaded safety valves, 3. circulation pipe 4. pressure meters, 5. unidirectional control valve 6. return ducts, 7. micro porous spray tubes 11. and emergent flap valve 8.The water inlet of electronic tubing pump 1 is connected with the outlet pipe of storage cistern 9, the delivery port of electronic tubing pump 1 is connected with flap valve 2, the other end of flap valve 2 is loaded onto single spring safety valve 3 backs by the pipeline string and is connected with water supply network 10, the two ends of emergent flap valve 8 are connected with water supply network 10 with storage cistern outlet pipe 9 respectively, one end of unidirectional control valve 6 is loaded onto pressure meter 5 backs with the pipeline string and is connected with water supply network 10, in addition-hold to be connected with micro porous spray tube 11 with circulation pipe 4.The pond lid 13 of storage cistern 12, the setting of overflow permeability cell 14 and filling pipe 15 and installation and known being as good as.
