Abstract
The utility model provides a water supply device without a bottom valve, which is used for sending water in a water source to the user. The utility model is provided with a water supplementing pipe and a water delivery pipe (2). The lower ends of the water supplementing pipe and the water delivery pipe (2) are positioned in the water source, and the upper parts are arranged in a negative pressure water tank (7) of which the bottom part is connected with a water drain pipe (4) and a water pump (10) on which a water delivery pipe (9) is connected. The water supply device does not use a bottom valve any more, and therefore, the trouble brought by replacing and maintaining the bottom valve is avoided. The utility model can realize automatic water supplement, but does not need the manual work to supplement the water to the water tank or fill the pump.
Description
The utility model provides a kind of water supply installation.
On existing water supply installation, bottom valve must be used in the water sucking mouth of water pump.When bottom valve leaks seriously, downtime, water system can enter air when long slightly, start preceding necessary pump priming once more.And when bottom valve is stuck, be difficult to water is filled by system too soon owing to leaking.Because bottom valve is positioned at the bottom in water source such as pond, therefore, changes and safeguard that bottom valve bothers very much.
The purpose of this utility model provides a kind of without bottom valve water supply installation, to improve the convenience of its use.
The utility model is to realize like this, a kind of without bottom valve water supply installation, the filling pipe that it has the lower end to be positioned at the water source is connected on the top of negative pressure water tank through self priming pump, the top that the lower end is positioned at the water inlet pipe at water source is installed in the negative pressure water tank, its delivery port is positioned at the negative pressure water tank upper, the outlet pipe that is connected on the negative pressure water tank bottom links to each other with water pump, is connected to flow pipe on the water pump.
Adopt the water supply installation of said structure,, therefore avoided bottom valve to damage the influence that water system is caused, eliminated and changed and safeguard the trouble that bottom valve brings owing to no longer adopt bottom valve.Because the position of each water pipe relation can realize automatic water supplement on the existence of negative pressure water tank and the negative pressure water tank, needn't often lean on artificial be water tank moisturizing or pump priming.
Below in conjunction with description of drawings structure of the present utility model.
Accompanying drawing is the schematic diagram of the utility model structure.
As shown in drawings, a kind of without bottom valve water supply installation at the utility model, the filling pipe (3) that it has the lower end to be positioned at the water source is connected on the top of negative pressure water tank (7) through self priming pump (1), the top that the lower end is positioned at the water inlet pipe (2) at water source is installed in the negative pressure water tank, its delivery port is positioned at the negative pressure water tank upper, the outlet pipe (4) that is connected on the negative pressure water tank bottom links to each other with water pump (10), is connected to flow pipe (9) on the water pump.
Before the use, with self priming pump the negative pressure water tank is filled water earlier.When water pump when water tank absorbs water, form negative pressure in the water tank, so the water in water source such as the pond is pressed in the negative pressure water tank by atmospheric pressure by water inlet pipe.Because outlet pipe is connected negative pressure water tank bottom, little air is on top in the case, and air can not enter the pump housing, also just can not influence the work of water pump (being generally common centrifugal water pump).When shutting down, because the water inlet pipe delivery port of water tank is than higher, the water in the negative pressure water tank can not flow back in the water source.Water in the case adds under the effect of gravity in the water pump automatically, can start shooting at any time and send water, and water is delivered to the user through flow pipe.
If certain user's water tap is lower than the horizontal level of negative pressure water tank in water system, under situation about growing downtime, the water in the negative pressure water tank may be blotted under the siphonage effect, causes to start shooting next time.For avoiding the generation of this problem, can in the negative pressure water tank, settle liquid-level switch (5), (6), and liquid-level switch is linked to each other with the water pump control cabinet.In a single day water level in the run duration negative pressure water tank is lower than lower limit, i.e. the position at liquid-level switch (5) place, and switch board stops water pump operation immediately, open self priming pump moisturizing in the case, when water level reaches the upper limit, promptly during the position at liquid-level switch (6) place, just close self priming pump, open water pump and do.
The negative pressure water tank upper can also have automatic blow off valve valve air relief (8), when self priming pump during moisturizing, can be emitted air in case automatically.
