Abstract

The utility model relates to a set of water supply facilities which is provided with a fault feedback device for the internal drainage of a check valve. The facilities comprise a water supply network, a water pump, the check valve, an air pressure tank and a pool, and are characterized in that a flow switch is mounted on a connecting pipe which is horizontally arranged between the water pump and the check valve, and is correspondingly connected with a sound and light signal. The facilities have the following advantages: fault can be fed back to a control center at the first time, and can be found in time, so that the troubleshooting time is saved; the problem that the facilities need to be started frequently, or even cannot be stopped caused by the internal drainage of the check valve is solved in time, so that not only the service life of the water pump is prolonged, but the operating cost is saved; and the condition that the pool (or a water tank) is overflowed due to long time backflow of water can be effectively prevented, and valuable water resource is saved.

Description

Add the unitized water supply equipment of letting out the fault feedback device in the loaded check valve
Technical field
The utility model relates to a kind of unitized water supply equipment, particularly a kind of unitized water supply equipment of letting out the fault feedback device in the loaded check valve that adds.
Background technology
Present unitized water supply equipment (see figure 1) is the start and stop that come control of pump 12 according to the feedback of pressure-detecting device 11; when water supply network pressure is reduced to the apparatus settings starting pressure because of normal leakage or artificial water; water pump 12 starts (two water pump 12 alternate runs; standby each other); water supply network 13 is delivered in the pressurization of water in pond (or water tank); unnecessary water enters air pressure tank 14; when water supply network pressure reaches apparatus settings shutdown pressure; water pump 12 is shut down; flap valve 15 stops water to reflux; air pressure tank 14 is kept water supply network pressure; when pipe network 13 pressure are reduced to the apparatus settings starting pressure; water pump 12 starts ...; so go round and begin again; when letting out (sealing surface has reasons such as rubbish or sealing surface damage to cause the flap valve can not non-return) in the flap valve 15; fault can not in time not found and solve to the water pump frequent starting that can cause even can not shut down before the maintenance personal does not find and checks, thereby cause the interruption of water supply.
Summary of the invention
The purpose of this utility model is to have reasons such as rubbish or sealing surface damage to cause flap valve can not non-return to cause water supply network water reflux water pump frequent starting that causes even the problem that can not shut down because of the sealing surface of letting out in the flap valve in order in time to find and solve present water supply facilities; strengthen the remote detection of control centre simultaneously, improved the up-to-dateness of pump house equipment fault.A kind of unitized water supply equipment of letting out the fault feedback device in the loaded check valve that adds is provided.The utility model design adds the unitized water supply equipment of letting out the fault feedback device in the loaded check valve, comprise water supply network, water pump, flap valve, air pressure tank, pond, it is characterized in that: on the tube connector that is horizontal positioned between water pump and the flap valve, flow switch is installed, sound and light signal of the corresponding connection of flow switch.The utility model has the advantages that the very first time feeds back to control centre with fault, in time find fault, reduced the malfunction elimination time; In time solved the problem of equipment, both prolonged water pump application life, saved running cost again because of letting out frequent starting in the flap valve even can not shutting down; The long-time situation that causes pond (or water tank) overflow that refluxes of effectively anti-sealing takes place, and has saved precious water resource.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic diagram,
Accompanying drawing 2 is a structural representation of the present utility model,
Accompanying drawing 3 is the A portion enlarged diagram of Fig. 2 of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
Comprise water supply network 1, water pump 2, flap valve 3, air pressure tank 4, pond 5 among the figure, it is characterized in that: on the tube connector that is horizontal positioned 6 between water pump 2 and the flap valve 3, flow switch 7 is installed, sound and light signal of flow switch 7 corresponding connections.
Install a small-sized flow switch 7 additional in the tube connector 6 of the horizontal positioned between 2 outlets of every water pump and outlet non-return valve 3, every flow switch sound and light signals of 7 corresponding control centres (or other failure alarm signal), cause water to reflux to pond 5 (or water tank) in case let out in the flap valve 3 by water supply network 1, flow switch 7 actions this moment, (this process is to confirm the continuation of backflow through a time-delay, in case the flow switch snap action causes false alarm, delay time can be according to the actual conditions Field adjustment) confirm after, send corresponding sound and light signal (or other signal alarm signal) to control centre, the staff can adjust the equipment operation condition and directly go field maintenance to fix a breakdown according to signal feedback, in the unitized water supply equipment pipeline, add and let out the fault feedback device in the loaded check valve, strengthened the remote detection of control centre, made the investigation of equipment fault is moved towards initiatively by passive equipment fault.
