Abstract

The invention relates to a tap water pressure-bearing tank. The tap water pressure-bearing tank comprises a tank body, a water outlet is formed at the bottom of the tank body, and a water inlet is formed at the top of the tank body. An automatic switch valve is arranged at the top of the tank body, the automatic switch valve comprises a valve body, the interior of the valve body is of a hollow structure, a upper opening and a lower opening are formed in the valve body, a floater is arranged in the valve body, the upper opening of the valve body is in a circular shape, and the lower opening of the valve body is in a polygon shape; the floater is in a sphere shape, the diameter of the floater is larger than the diameter of the upper opening, and the inner wall of the top of the valve body is in an outer arc shape. When the tank body is filled with water, the floater floats upward under the buoyancy of the water, the upper opening is plugged by the floater, and discharge pressure is the intake pressure of the water; when the water supply is cut off, a water level declines, the floater falls, an air inlet where the air can get into the tank body is formed by the upper opening and the lower opening, ordinary pressure is formed, and the water supply mode of the water in the tank is in an atmospheric pressure water supply mode. The tap water pressure-bearing tank comprises only one tank body, and is simple in structure, the pressure-bearing water supply can be achieved when the water supply is normal, and the atmospheric pressure water supply can be also achieved when the water supply is cut off.

Description

Tap water pressure-bearing water pot

[ technical field]

The present invention relates to daily living article field, particularly relate to a kind of tap water pressure-bearing water pot.

[ background technology]

Existing water pot is divided into pressure-bearing type water pot and gerotor type water pot, the gravity of what the discharge pressure of gerotor type water pot leaned on is water, and pressure is less; The discharge pressure of pressure-bearing type water pot and tap water intake pressure are suitable, and pressure is comparatively large, but can not use when water inlet is cut off the water, and as also there being water can with just increasing water tank or inner bag when will cut off the water, so just become two water pots, complex structure, cost be high.

[ summary of the invention]

The object of the present invention is to provide a kind of structure simple, can supply water and the tap water pressure-bearing water pot of retaining, be intended to solve the problem that normal water supply hydraulic pressure is little, do not have water for subsequent use, many bladder structures complexity when cutting off the water.

The present invention is achieved in that a kind of tap water pressure-bearing water pot, comprise water pot, delivery port is had bottom described water pot, top has water inlet, described water pot top is provided with automatic open and close valve, described automatic open and close valve comprises valve body, described valve inner is hollow structure, described valve body has upper shed and under shed, and there is a float inside, and described valve body upper shed is circular, under shed is polygon, described float is spherical, and float diameter is greater than upper shed diameter, and the inwall of described body top is outer arcuate.

Further technical scheme of the present invention is: described water pot top is also provided with relief valve.

The invention has the beneficial effects as follows: owing to adopting technique scheme, water filling in water pot, when water is full, float is subject to buoyancy of water floating, and upper shed is blocked by float, and discharge pressure is tap water intake pressure; When cutting off the water, during water level decreasing, float drops, upper shed and under shed form the air inlet port to water pot air inlet, form normal pressure, and the water in water tank is that gerotor type supplies water; Only comprise a water pot, structure is simple, can complete pressure-bearing type and supply water during normal water supply, also can supply water by gerotor type when cutting off the water.

[ detailed description of the invention]

Below in conjunction with the drawings and specific embodiments, the present invention is described further.

As shown in Figure 1, a kind of tap water pressure-bearing water pot, comprises water pot 1, and have delivery port 3 bottom described water pot 1, top has water inlet 2, and described water pot 1 top is provided with automatic open and close valve 4.

As shown in Figure 2, Figure 3 and Figure 4, described automatic open and close valve 4 comprises valve body 41, described valve body 41 inside is hollow structure, described valve body 41 has upper shed 42 and under shed 43, and there is a float 44 inside, and described valve body 41 upper shed 42 is circular, under shed 43 is polygon, described float 44 is spherical, and float 44 diameter is greater than upper shed 42 diameter, and the inwall at described valve body 41 top is outer arcuate.

The inwall at valve body 41 top is outer arcuate, is convenient to automatically to navigate to upper shed 42 place when float 44 floats; Because float 44 diameter is greater than upper shed 42 diameter, and be circle, therefore float 44 is blocked suitable for reading by water floatage energy; Because under shed 43 is polygon, therefore float 44 with bottom water level decreasing to valve body 41 time, float 44 and under shed 43 can not block completely, avoid the formation of negative pressure in water pot 1, affect water pot 1 and supply water.

In water pot 1 during water filling, upper shed 42 uses as exhaust opening, and under shed 43 uses as exhaust opening or filling pipe end; When water is full, float 44 is subject to buoyancy of water floating, and upper shed 42 is blocked by float 44, and discharge pressure is tap water intake pressure; When cutting off the water, during water level decreasing, float 44 falls, and upper shed 42 uses as air inlet port, and under shed 43 uses as air inlet port or the lower mouth of a river, and form normal pressure, now water pot 1 provides gerotor type to supply water; Only comprise a water pot 1, structure is simple, can complete pressure-bearing type and supply water during normal water supply, also can supply water by gerotor type when cutting off the water.

Described water pot 1 top is also provided with relief valve 5.When water pot 1 receives effects such as expanding with heat and contract with cold, when internal pressure is excessive, energy releasing pressure automatically, shields.

As described in figures 1 and 5, tap water pressure-bearing water pot of the present invention both can have been made vertical, also can make horizontal.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
