Abstract
The utility model relates to an no-sucking-stroke (no-negative-pressure) water storage tank in water supply equipment, in particular to a box type sealed pressured water storage tank of big volume, which comprises a tank body and a vacuum compensator mounted on the top cap of the body. The tank body is provided with a water intake pipe and a water-out pipe. Between the water-out pipe and a water pump, a check valve is provided. A pressure-withstanding lacing wire and a pull pipe can be solid or hollow in the tank body in longitudinal and transversal direction. The tank body is sealed and can withstand pressure. The tank has a big water storage volume, long time in compensating water, no secondary pollution, is safe and reliable.
Description
Technical field
The utility model relates to a kind of box big capacity water storage device of pressure that is sealed with of inhaling journey (no negative pressure) supply equipment that is used for not having.
Background technology
Along with The development in society and economy, people are more and more higher for guaranteeing healthy requirement to the drinking water quality safety non-pollution.From the frequency-changing water supply device of pond water tank suction,, can't guarantee that water quality safety is pollution-free in the secondary pressure process owing to can not seal.My another patent " a kind of intelligent suction-stroke-free water supply facilities of direct serial connection tap water pipe network " (CN02214076.X) discloses a kind of nothing and has inhaled the journey supercharging equipment, thoroughly avoided taking place in the secondary water-supply phenomenon of secondary pollution, again municipal network water supply has not been had negative pressure and produce.But the water storage device of this equipment only under the municipal water supply normal condition, could satisfy user's water because the water amount is few, if city planting ductwork is cut off the water or underfed, the user is anhydrous immediately to be supplied.
Summary of the invention
The purpose of this utility model provides a kind ofly cuts off the water or during underfed, in 1-5 hour, box being sealed with of supplying water to the user pressed big capacity water storage device continuously when city planting ductwork, and being installed on does not have the journey (no negative pressure) of suction supply equipment water pump front end.
For achieving the above object, the utility model adopts following technical scheme:
Box being sealed with described in the utility model presses big capacity water storage device to comprise casing, be installed in the vacuum compensation device on the box top, have water inlet pipe and outlet pipe on the casing, be connected with the valve check device between outlet pipe and the water pump, box sealing, in length and breadth to pressure-bearing lacing wire and trombone slide are set, the two ends of pressure-bearing lacing wire are fixedly connected on the two side of casing correspondence in the casing.
Above-mentioned pressure-bearing lacing wire is square tube or pipe, can be hollow or real core.
Above-mentioned water inlet pipe is arranged on the end face of casing, also has the cleaning inlet of sealing on the end face of casing, and outlet pipe is arranged on the lower end sidewall of casing, and outlet pipe connects water pump by valve flap valve and feed pipe.
Described vacuum compensation device comprises the electromagnetic valve and the liquid level sensor that is installed in the casing that is installed on interior evacuated tube and the installation evacuated tube.
After adopting technique scheme, the utlity model has following advantage:
1, moisture storage capacity is big, the water yield make-up time is long.Cut off the water or in time of water shortage, the nothing of this device is installed inhales journey (no negative pressure) supply equipment at city planting ductwork, still can successively supply water to the user at 1-5 hour.
2, box sealing and energy pressure-bearing, municipal ductwork pressure fully obtains utilizing.Municipal ductwork pressure lowers pump variable frequency frequency in service, has reached the purpose of further economize on electricity joint money.
3, box sealing non-secondary pollution, water quality is fresh.Because the running of water pump, the water source source and course is to the client, and tap water time of staying in casing only be a several hrs, so does not have the retaining pollution problems, the energy-conservation again cleaning charge of water tank and water pool.
4, it is reliable to accept low water pressure safety.The city planting ductwork pressure of supply water is 1.0-3.5kg, and there is not the safety problem of leakage in " box be sealed with press big capacity water storage device " bearing capacity 14kg.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the structural representation of another embodiment of the present utility model.
The specific embodiment
As shown in drawings, described in the utility model box be sealed with press big capacity water storage device comprise sealing casing 1, be installed in the vacuum compensation device 2 on casing 1 end face, have water inlet pipe 3 and outlet pipe 4 on the casing 1, water inlet pipe 3 is arranged on the end face of casing 1, the cleaning inlet 6 that also has sealing on the end face of casing 1, outlet pipe 4 is arranged on the lower end sidewall of casing 1, and outlet pipe 4 connects water pump 8 by valve flap valve and feed pipe 5.In length and breadth to pressure-bearing lacing wire and trombone slide 7 are set, pressure-bearing lacing wire and trombone slide 7 can be that metal side tube also can be a pipe, can be that real core or hollow are fixedly welded on the two side of casing 1 correspondence in the casing 1.Electromagnetic valve and the liquid level sensor 9 that is installed in the casing 1 on evacuated tube 21 and the installation evacuated tube 21 are arranged in the vacuum compensation device 2.
During use, tap water enters casing 1 by water inlet pipe 3, and the electromagnetic valve in the vacuum compensation device 2 is opened, and the air in the casing is discharged from the rising of the water surface, and up to casing 1 is filled, vacuum compensation device 2 cuts out.Because casing 1 is a seal and pressure bearing, tap water pressure makes full use of, and is added by pump variable frequency and presses to user's water supply.At this moment, have the pressure of city planting ductwork in the casing 1, help to reduce the running frequency of pump, alleviate load.When water inlet pipe 3 pressure reduce; along with the water in the casing 1 reduces gradually, the pressure in the casing 1 reduces gradually, when being lower than the water level protection value of control device 10 settings; control device 10 electromagnetic valve of instruction are opened, and avoid producing vacuum at casing 1 city planting ductwork is produced negative pressure.
The effect that pressure-bearing lacing wire and trombone slide 7 are set in casing 1 in length and breadth is to avoid the pressure of the static pressure of water and pipe network to make the casing modification.
When water inlet pipe 3 pressure recover just often, casing 1 is full of water automatically, and vacuum compensation device 2 is opened automatically, discharges the air in the casing, and the electromagnetic valve in the vacuum compensation device cuts out automatically, and equipment drops into the normal water supply operation.
As shown in Figure 1 and Figure 2, casing 1 can be that tetragonal body also can be a cylinder.
