Description

Building dual system water supply automatic transfer equipment

The utility model belongs to a kind of building dual system water supply automatic transfer equipment.

The method of supplying water that building is commonly used is divided into two kinds at present: a kind of is that municipal water supply system (being called for short big system) supplies water directly for the building user; Another kind is that big system supplies with surface water supply station (or roof accumulator) with water, comes water to store, pressurize the back to building user water supply big system by surface water supply station (or roof accumulator) again, can claim the mini system method.Distinguish astatically and higher building adopts the mini system method to supply water mostly for big system hydraulic pressure.But there are the following problems to adopt this method to supply water, under the situation of mini system operate as normal, big system can not be directly to being lower than the floor water supply of its of water level the same period, wasted this part pressure of big system, no matter the building high level still is the water of low layer, all need with water be forced into top more than, so not only increased energy consumption, and strengthen mini system load and capacity, and prolonged the running time of mini system, shortened its application life.

It is a kind of under the situation of mini system work that the purpose of this utility model is to provide, and utilizes big system water to compress into row control, automatically the conversion building dual system water supply automatic transfer equipment of supplying water directly for the floor that is lower than its of water level by big system the same period.

For achieving the above object, solution of the present utility model is that the secondary valve formula of the type block valve that surges is installed between floor intake pipe and the mini system water inlet pipe, the pressurization conduit that is arranged on the mini system water inlet pipe links to each other with the main valve working chamber of this valve, be contained in that bypass pipe and big system water inlet pipe links to each other on the floor intake pipe, be equipped with in the bypass pipe with the user side to the flap valve that is opening direction, the control conduit that is contained on the big system water inlet pipe is connected with the secondary valve working chamber of this valve, set reduced pressure conduit is connected on the control conduit on the main valve working chamber, and the secondary valve that surges is contained on pressurization conduit and the reduced pressure conduit.Utilization enters the hydraulic pressure that big system in the secondary valve working chamber comes water through the control conduit, controls the keying of this valve main valve, when main valve is closed, has blocked the mini system water channel, and big system water presses off flap valve, supplies water to the user through bypass pipe.When main valve was opened, mini system supplied water to the user, and closed the flap valve in the bypass pipe, thereby had blocked the water supply of big system.

Because of the utility model secondary valve formula of type block valve that will surge is installed on each floor intake pipe of mini system water supply building, connect big system by being connected the bypass pipe that has flap valve on each floor intake pipe.So under the situation of mini system work, can effectively utilize the hydraulic pressure of big system, automatically conversion supplies water directly for each floor that is lower than its of water level by big system the same period, thereby cuts down the consumption of energy, and reduces the capacity and the load of mini system, prolongs mini system application life.

Reach embodiment in conjunction with the accompanying drawings concrete structure of the present utility model is described.

Fig. 1-be substitutional connection schematic diagram of the present utility model.

Fig. 2-be the structure sectional view of the utility model embodiment.

As shown in the figure, the existing secondary valve formula of the type block valve that surges that the utility model adopts is mainly by the main valve 2 that surges (comprising elements such as hydraulic actuator, valve body, valve gap, valve seat, valve are distinguished, valve rod), main valve return mechanism 3, main valve working chamber 4, the secondary valve 5 that surges (its element that comprises is identical with the element of the main valve 2 that surges), compositions such as secondary valve return mechanism 6, secondary valve working chamber 7, the hydraulic actuator of the main valve 2 and the secondary valve 5 that surges of surging in the present embodiment all adopts diaphragm type, also can adopt plunger piston type, piston-type, float-plane version etc.The main valve 2 that will surge is installed between each floor intake pipe 18 and mini system water inlet pipe 12 that big system hydraulic pressure can supply, the pressurization conduit 10 that is connected on the mini system water inlet pipe 12 is connected with main valve working chamber 4, the bypass pipe 17 that is installed in the floor water intaking 18 is connected with system's water inlet pipe 15 greatly, be equipped with the user side to the flap valve 16 that is opening direction junction at bypass pipe 17 and big system water inlet pipe 15, the control conduit 9 that is contained on the big system water inlet pipe 15 is connected with secondary valve working chamber 7, be arranged on the main valve working chamber 4 reduced pressure conduit 8 be connected in secondary valve working chamber on control conduit 9 link to each other, be contained in adding of the secondary 5 pairs of main valve working chambers 4 of valve that surge on reduced pressure conduit 8 and the pressurization conduit 10, decompression is controlled, and at pressurization conduit 10 and the intake of controlling conduit 9 filter screen 11 is housed all.Mini system water inlet pipe 12 and big system water inlet pipe 15 are connected on mini system feed pipe 13 and the big system water supply pipe 14, and floor intake pipe 18 is linked to each other with user's intake pipe 19.Under the situation of mini system work, when big system comes water when control conduit 9 enters in the secondary valve working chamber 7 and reaches the pressure (being preferably in 0.01-0.04MPa) of setting, the secondary valve 5 that surges is subjected to hydraulic action to cut out reduced pressure conduit 8, open pressurization conduit 10 simultaneously, mini system comes water to inject main valve working chamber 4 through pressurization conduit 10, and the main valve 2 that surges is closed by hydraulic action, has blocked the mini system water channel, big system water presses off flap valve 16, and 17 couples of users supply water through bypass pipe; Big system water in entering secondary valve working chamber 7 is forced down when setting value, under the return effect of secondary valve return mechanism 6, the secondary valve 5 that surges cuts out pressurization conduit 10, open reduced pressure conduit 8, make 4 decompressions of main valve working chamber, open main valve 2 under the 3 return effects of main valve return mechanism, mini system supplies water to the user, and pressing off flap valve 16, big system stops to supply water.
