The device can be directly connected on a tap water net to conduct with pressurizing water supply, which can not make the water pressure in the tap water net form negative pressure to affect the water pressure of other users, and can not cause water secondary pollution.
Description
Technical field
The utility model relates to a kind of full-automatic non-negative pressure supply equipment.
Background technology
The pressure of present tap water pipe network, because of the hydraulic pressure deficiency, can not satisfy the requirement of all high rise building water supplies, for satisfying the highrise building problem of water consumption, usually adopt the method for secondary pressurization, concrete measure is: establish high level cistern at roof, build reservoir and directly connect high-pressure pump at the tap water pipe network.And the user establishes high level cistern at roof, builds supporting facility such as reservoir, and investment is big, and floor space is big, and water is easily contaminated, rotten, problems such as also easily metalling run out, seep water, leak causes the waste of water resource; At the online high-pressure pump that directly connects of running water pipe, easily make the hydraulic pressure in the tap water pipe network form negative pressure, influence other users' hydraulic pressure, do not meet the requirement of national relevant law, rules yet.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of full-automatic non-negative pressure supply equipment that running water pipe carries out pressurizing feedwater on the net that is directly connected to.
For solving the problems of the technologies described above, the utility model comprises the flow regulator that is serially connected on the water supply pipe, between flow regulator and user pipe, be parallel with water pump assembly pipeline and bypass line by water supply line, be serially connected with flap valve and gate valve on the pipeline at water pump assembly and bypass pipe place, water pump assembly is connected with switch board through signal control line, its design feature is to be provided with the teletransmission pressure sensor on user pipe, pressure sensor is installed on flow regulator, negative pressure cancellation element and liquid level detector, pressure sensor, liquid level detector and teletransmission pressure sensor are connected with switch board through signal control line, on the water pump assembly pipeline shock-absorbing connection are installed.
As to improvement of the present utility model, described water pump assembly pipeline is the parallel two-tube road.
As to further improvement of the utility model, gate valve and backflow preventer are installed on the water supply pipe of flow regulator front end.
After adopting said structure, it is online that this equipment can be directly connected to running water pipe, infrastructure such as water tank, pond have been replaced by flow regulator, small investment, compact conformation, reduced floor space, and can not cause water pollution, avoided causing water resource waste because of metalling run out, seep water, leak etc.; And pressure sensor, negative pressure cancellation element and the liquid level detector that is connected with the switch board signal is installed on flow regulator, avoid the hydraulic pressure in the tap water pipe network is formed negative pressure, influence other users' hydraulic pressure, bypass pipe is set, can when equipment has a power failure, supplies water to the user by the former pressure in the tap water pipe network.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
With reference to accompanying drawing, this full-automatic non-negative pressure supply equipment, comprise the flow regulator 6 that is serially connected on the water supply pipe, this flow regulator 6 can be a stainless steel tank body, and gate valve 2 and backflow preventer 3 are installed on the water supply pipe 1 of flow regulator 6 front ends.Between flow regulator 6 and user pipe 20, be parallel with water pump assembly pipeline 12 and bypass line 9 by water supply line 8; water pump assembly pipeline 12 is the parallel two-tube road; when breaking down shutdown for one group, then start another group and work on, or two groups of water pump alternations.Be serially connected with flap valve 16 and gate valve 10 on the pipeline at water pump assembly 13 and bypass pipe place; it is the aqueous reflux that prevents in the user pipe of water pump shutdown back that flap valve is set; gate valve is set is convenient to equipment and pipeline maintenance; bypass pipe 8 is set, can when equipment has a power failure, supplies water to the user by the former pressure in the tap water pipe network.Water pump assembly is connected with switch board 21 through signal control line, on user pipe 20, be provided with teletransmission pressure sensor 17, pressure sensor 5, negative pressure cancellation element 4 and liquid level detector 7 are installed on flow regulator 6, negative pressure cancellation element 4 is a mechanical type, adopt ball float 14 to realize its switch, liquid level detector 7 adopts liquid level float ball chuck 18 and liquid level ball float 15 formula frame for movements.Pressure sensor 5, liquid level detector 7 and teletransmission pressure sensor 17 are connected with switch board 21 through signal control line, when the liquid level detector sensed water level is in the lower position, then water pump assembly quits work, the negative pressure cancellation element is the supplemental insurance device of liquid level detector, when water in the flow regulator is full, vacuum breaker is closed, and in the flow regulator during drawdown, therefore vacuum breaker is opened, and the flow regulator inner chamber communicates with ambient atmosphere, when in the flow regulator such as grade when anhydrous, even two groups of pump workings, the just gas of being taken out is avoided the hydraulic pressure in the tap water pipe network is formed negative pressure, influences other users' hydraulic pressure.On water pump assembly pipeline 12, the two ends of water pump assembly 13 are equipped with shock-absorbing connection 11, to reduce pipeline vibration.
