Abstract
The utility model discloses a straight water-supply device which has no negative pressure and can convert frequency and increase pressure automatically. The utility model consists of a water inlet valve 1, an enclosed water tank 2, a control box 4, a pressurizing water pump group 6-13, a check valve 14, and a valve 15. A pair of hole combination-type exhaust valves 3 are arranged on the top of the enclosed water tank 2 which is provided with a water-level switch 18 inside. The enclosed water tank is connected with a water inlet pipe in tangent way. A pressure sensor 16 is arranged between a water outlet 19 and the control box 4. A pressure switch 5 is arranged between the water inlet and the control box 4. The technical proposal of the utility model has the advantages that the utility model can supplement the pressure by successfully using the water pressure of the city pipeline network; and the water supply can be regulated in electrodeless way. With stable water pressure, the utility model has no problem that the forced dipping of the negative pressure affects the water supply of the city pipeline network. And the utility model solves the problems of the following-back of water and the secondary pollution; moreover, the utility model is water-saving, electricity-saving, safe and reliable.
Description
Technical field
The utility model relates to a kind of supply equipment.
Background technology
Because the tap water pressure that uses is on the low side at present, particularly summer and water use peak phase every day floor slightly height hydraulic pressure just to occur low even the phenomenon of cutting off the water supply occurs, for solving not foot phenomenon of hydraulic pressure, the common practice is at the top layer of building water tank to be installed, feed tank supplies water when the water ebb, water tank supplies water for the resident family of high floor by water pipe again, though this method solves the problem of pressure of supply water deficiency, exists comparatively serious hygienic quality problem.
Summary of the invention
The purpose of this utility model is at the pressure of supply water deficiency that exists in the prior art, the antihygienic defective of water quality and a kind of supply equipment is provided.
For solving the technical problem of above-mentioned existence, the utility model adopts following technical proposals: be provided with water level switch 18 in the sealed water storing tank 2 of this equipment, diplopore mouth combination exhaust valve 3 is equipped with at sealed water storing tank top, water inlet pipe 19 is connected with tangential way with sealed water storing tank 2 surfaces, be provided with pressure sensor 16 between equipment delivery port and the control cabinet 4, the inlet end that is connected with city planting ductwork is provided with a pressure switch 5.
The utility model compared with prior art, its beneficial effect is:
1. the start emptying is simple, and time saving and energy saving being convenient to operated.Because diplopore mouth combination exhaust valve has been installed at the top of sealed water storing tank, a large amount of gases when sealed water storing tank water-filling in the sealed water storing tank are discharged by diplopore mouth combination exhaust valve, making start prepare to oversimplify.
2. there is not the negative pressure influence that absorbs water by force.When city planting ductwork water supply wretched insufficiency, because the effect of diplopore mouth combination exhaust valve, no negative pressure of vacuum in the pipe can not drawn the water in the city planting ductwork by force.
3. employing variable frequency control, can be automatically according to the rotating speed of the size adjustment pressure pump group of water supply volume, can just automatically switch according to city planting ductwork hydraulic pressure and supply water or supply water by this equipment pressurization by city planting ductwork.Using electricity wisely so greatly, reduction expense.
4. solve the backflow and the secondary pollution problem of water, owing to adopted diplopore mouth combination exhaust valve, the air in its automatic device for transferring has solved the air bag that forms in the water and has hindered current, prevents water hammer, makes water supply more stable.In addition, owing to air is arranged in the water, pipeline and equipment inner surface alternately contact water and air and have quickened corrosiveness to interior surface thereof, adopt diplopore mouth combination exhaust valve, greatly weaken the corrosion phenomenon of pipeline and equipment inner surface, avoided the influence to water quality such as metallic residue.
5. owing to be provided with electromagnetic valve in the communicating pipe of municipal net and user network, user's pipe network water refluxes and pollution city planting ductwork water quality when avoiding negative pressure occurring with city planting ductwork.
