Description
1, technical field
The present invention relates to a kind of supply equipment, the non-negative pressure stabilized supply equipment of specifically a kind of direct-type that on pipe network, is connected in series.
2, background technology
Present supply equipment great majority are by the water pump pressurization of from pond, water tank, fetching water, and it takes up an area of big, and investment is high; But also can not utilize ductwork pressure; Have energy dissipation, severe water pollution also has part to adopt the direct-type non-negative pressure water-supply installation in addition; But the direct-type non-negative pressure water-supply installation of prior art is that current stabilization jar and regulating tank branch are arranged, and this all can not reach optimal effectiveness at aspects such as investment, occupation of land, installations.
3, summary of the invention
In view of the deficiency of above-mentioned prior art, the present invention provides a kind of little, reduced investment, energy saving in running and stable non-negative pressure stabilized supply equipment of direct-type of water supply of taking up an area of.
The technical solution adopted for the present invention to solve the technical problems is: the non-negative pressure stabilized supply equipment of direct-type is made up of non-negative pressure stabilized jar, negative pressure arrester, water pump and switch board, and non-negative pressure stabilized jar of inside is provided with interior end socket, and non-negative pressure stabilized jar is divided into plenum chamber and conditioning chamber two parts; Plenum chamber is connected with water inlet pipe, and on water inlet pipe, is provided with strainer and backflow preventer, and the negative pressure arrester is installed in plenum chamber top; Be provided with level sensor and draining valve in plenum chamber bottom, the plenum chamber water outlet is received water pump through pipeline, and walks around water pump and be provided with bypass pipe; Water (flow) direction is sequentially with flap valve and valve in the bypass pipe upper edge; And between flap valve and valve, adopt liaison tube to be connected to conditioning chamber, liaison tube is provided with draining valve, and conditioning chamber is connected by flange; In conditioning chamber, be provided with the rubber swelling air bag; Installing pressure meter in conditioning chamber top is provided with the pressure detecting table on outfall sewer, level sensor, water pump, pressure detecting table are wired to switch board respectively.
During operation; Current directly get into non-negative pressure stabilized jar plenum chamber by water inlet pipe behind strainer, backflow preventer, the air in the plenum chamber is discharged by the negative pressure arrester, and the negative pressure arrester cuts out behind the plenum chamber full water automatically; Water pump is the water intaking pressurization in the plenum chamber; When each supplies water with water spot, supply water to conditioning chamber by liaison tube, the rubber swelling air bag in the conditioning chamber compresses and the storage regulating pondage; When the inflow of water inlet pipe during less than the water yield of outfall sewer, the water level in the plenum chamber begins to descend, and the negative pressure arrester is opened and mended air, eliminating the pipe network negative pressure, and when the drawdown in the plenum chamber during to the lowest water level set, the water pump shutdown; Treat water level in the plenum chamber rise to setting open the pump water level time, water pump starts automatically, and returns to the normal water supply state.When water inlet pipe pressure can satisfy the constant pressure value requirement that the pressure detecting table is set, water pump is shut down, and with water spot supplied water by bypass pipe this moment to each.
The increasing of water pump operation platform number, subtract when causing discharge pressure fluctuation, changes in flow rate with handoff procedure, the rubber swelling air bag in the conditioning chamber is regulated flow and stable water supply pressure adaptively according to the situation of pressure oscillation, changes in flow rate.The rubber swelling air bag of conditioning chamber, was shut down by predefined programme-control water pump through detecting the operation condition of water pump low frequency at night during the low discharge water; The rubber swelling air bag is sent to each with the regulating pondage in the conditioning chamber and supplies water with water spot, and along with the minimizing of regulating pondage, the pressure of rubber swelling air bag reduces; Make the pressure of pressure detecting table be lower than setting open pump pressure the time; Water pump starts automatically, also moisturizing in conditioning chamber again, and is so multiple past, to realize the energy-saving effect of low discharge operation.
Conditioning chamber adopts the flange purpose of connecting, is the maintenance and the replacing of rubber swelling air bag for ease.
The invention has the beneficial effects as follows, directly be connected in series water supply with pipe network and do not produce negative pressure, can make full use of ductwork pressure and reach energy-saving effect, and take up an area of little, reduced investment, pressure of supply water is stablized; The conditioning chamber employing rubber swelling air bag of non-negative pressure stabilized jar of while makes gas, separated form water, and the gas of having avoided gas, water directly to contact consumes the problem of the tonifying Qi of becoming estranged, and the connection of conditioning chamber employing flange, and maintenance conveniently.
