Abstract
The utility model relates to a pot-within-pump non-negative-pressure water supply apparatus, comprising an urban water intake pipe, a non-negative-pressure stable current regulator, a negative canceller, an electric contact pressure meter, an electromagnetic valve, a remote pressure meter, a pressure regulation pot and a control cabinet; wherein, the urban water intake pipe is connected with the non-negative-pressure stable current regulator through a water intake valve and connected with a by-pass pipe via a valve. The upper part of the non-negative-pressure stable current regulator is provided with an end cover. A diving pump is arranged in the non-negative-pressure stable current regulator through a fixing supporting frame and a hole board; the outlet of the diving pump is connected with a connection pipe through a check valve and a butterfly valve; and the other end of the connection pipe is connected with the by-pass pipe. The control cabinet is fixed on the lateral surface of the non-negative-pressure stable current regulator. Besides the advantages of the general non-negative-pressure water supply apparatus, the pot-within-pump non-pressure water supply apparatus in the utility model has the advantages of small area occupying, convenient maintenance and non-noise.
Description
Technical field
The utility model relates to a kind of fire water supply equipment, especially a kind of directly pump no-negative-pressure water supply equipment from the jar of city planting ductwork water intaking.
Background technology
At present, in utilizing the secondary booster water supply facilities of city planting ductwork overbottom pressure, all adopt non-negative pressure stabilized adjuster to cooperate the form of booster water pump or band water tank, booster water pump is arranged at outside current stabilization adjuster and the water tank, this water supply facilities noise is big, and maintenance and maintenance are inconvenient, and the occupation of land space is also big.
Summary of the invention
The purpose of this utility model just provide a kind of simple in structure, floor space is little, easy to maintenance, noiseless jar in the pump no-negative-pressure water supply equipment.
Pump no-negative-pressure water supply equipment in of the present utility model jar, comprise municipal water inlet pipe, non-negative pressure stabilized adjuster, the negative pressure arrester, electro connecting pressure gauge, electromagnetic valve, flap valve, the dish valve, the teletransmission pressure meter, vacuum tank, switch board, the municipal administration water inlet pipe inserts in the non-negative pressure stabilized adjuster through water intaking valve, the municipal administration water inlet pipe also links to each other with bypass pipe by valve, non-negative pressure stabilized adjuster top is provided with end cap, the negative pressure arrester, electro connecting pressure gauge and electromagnetic valve are installed on the end cap, submersible pump is installed in the non-negative pressure stabilized adjuster by fixed support and orifice plate, the diving delivery side of pump is through flap valve, the dish valve links to each other with tube connector, the other end of tube connector inserts bypass pipe, and switch board is fixed on the non-negative pressure stabilized adjuster side.
Pump no-negative-pressure water supply equipment in of the present utility model jar, it is a kind of remodeling no-negative-pressure water supply equipment that is directly installed on the water supply pipe, the municipal tap water enters municipal water inlet pipe, when the city planting ductwork water pressure energy satisfies user's water supply requirement, water directly supplies water to the user through valve, bypass pipe, promptly directly supplies water by the equipment bypass; When city planting ductwork water supply can not be satisfied the requirement of user's water, the water of city planting ductwork enters non-negative pressure stabilized adjuster, the negative pressure arrester is regulated non-negative pressure stabilized adjuster internal and external pressure balance, allow water be full of non-negative pressure stabilized adjuster so that normal the conveying, in the pipe network water supply quantity not sufficient, when municipal administration water inlet in-pipe flow sky or non-negative pressure stabilized adjuster internal gas pressure are lower than atmospheric pressure, drawdown in the non-negative pressure stabilized adjuster, negative pressure arrester and electromagnetic valve are devoted oneself to work, make and keep atmospheric pressure in the non-negative pressure stabilized adjuster, be unlikely to city planting ductwork is produced negative pressure, water supply volume increase as the user, when the hydraulic pressure that the teletransmission pressure meter measures city planting ductwork is lower than the required water supply pressure of user, automatically start submersible pump, regulate the hydraulic pressure in the pipe network, be increased to the required pressure of supply water of user up to ductwork pressure, guarantee that pipe network is in stable constant pressure water supply state always.Maintenance and when safeguarding, at first close the adjuster water intaking valve, open the water in the draining valve drain tank, at this moment, the original press water that has certain head more than needed of city planting ductwork can continue to supply water to the low layer user by the equipment bypass, open non-negative pressure stabilized adjuster top end cover, take submersible pump water outlet adpting flange apart and can take out the steel submersible pump and carry out repair and maintenance work.
Pump no-negative-pressure water supply equipment in of the present utility model jar, except that advantage with common no-negative-pressure water supply equipment, the following advantage of tool also:
1, booster pump adopts all steel submersible pump and is installed in the non-negative pressure stabilized adjuster, realizes integral structure, adopts the overflow-type water cooling, the subwoofer operation;
2, non-negative pressure stabilized adjuster adopts detachable structure, good seal and field-strip easy maintenance.
