Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Hereinafter implement
Example is used for illustrating the present invention, but is not limited to the scope of the present invention.
As shown in figures 1 to 6, a kind of structure utilizing differential water pressures to control switch on and off electricity, including pedestal 1, it is arranged on pedestal 1
Water inlet pipe 2 on sidewall and be arranged on the outlet pipe 3 at pedestal 1 top, described water inlet pipe 2 is provided with valve 4, described pedestal 1
Inside be provided with the fixing seat 5 connected with water inlet pipe 2, the inside of fixing seat 5 is provided with the hydraulic pressure switch storehouse 6 connected with water inlet pipe 2,
Top end within hydraulic pressure switch storehouse 6 is provided with pressure adjustable check valve 7, and the top of pressure adjustable check valve 7 is solid by plug 8
Fixed, the left and right sides wall in hydraulic pressure switch storehouse 6 is respectively equipped with the first pod apertures 9 and the second pod apertures 10, hydraulic pressure switch storehouse 6 is internal
Being provided with by the spring diaphragm 11 inserted bottom fixing seat 5, seesaw push rod 12 connecting valve support is passed through in the bottom of spring diaphragm 11
13, the inside of switch bracket 13 is fixed with power switching device 14, and the top of power switching device 14 is provided with and seesaw push rod 12 bottom
The on & off switch 15 of contact.
The differential water pressures that utilizes of the present invention controls the structure of switch on and off electricity, in the fixing seat 5 on the right side of described spring diaphragm 11
Portion is provided with and fixes the integrated boss of seat 5 16.
The differential water pressures that utilizes of the present invention controls the structure of switch on and off electricity, and described spring diaphragm 11 is by hydraulic pressure switch storehouse 6
Inside is divided into left cavity 17 and right cavity 18, and left cavity 17 and right cavity 18 are respectively by the first pod apertures 9 and the second pod apertures
10 connect with the internal cavities of pedestal 1.
The differential water pressures that utilizes of the present invention controls the structure of switch on and off electricity, and the inside of described spring diaphragm 11 is inlaid with plays
The door shape support member 19 of supporting role.
The differential water pressures that utilizes of the present invention controls the structure of switch on and off electricity, and the cross section of described seesaw push rod 12 is L-shaped knot
Structure, the top of seesaw push rod 12 is plugged on the inside of described spring diaphragm 11 after passing switch bracket 13.
The present invention utilize differential water pressures control switch on and off electricity structure, the top end face of described switch bracket 13 be provided with
The fixing groove 20 that spring diaphragm 11 bottom face matches, the bottom face of spring diaphragm 11 realizes sealing in being fixed on fixing groove 20 to be made
With.
The differential water pressures that utilizes of the present invention controls the structure of switch on and off electricity, and described switch bracket 13 is fixed on by screw 21
On the bottom face of fixing seat 5.
The present invention utilizes the structure of differential water pressures control switch on and off electricity when specifically used, and Natural Water is entered by water inlet pipe
Entering in left cavity, the water in left cavity enters in pedestal, in pedestal by the first pod apertures and pressure adjustable check valve
Water enters into right cavity by the second pod apertures, and the water in pedestal is discharged outside by outlet pipe simultaneously.Due to the water in pedestal
Directly discharging through outlet pipe, therefore the hydraulic pressure in pedestal is extremely low, the hydraulic pressure in right cavity is equal to the hydraulic pressure in pedestal.Work as water inlet
When pipe hydraulic pressure is more than 0.03MPa, owing to the first pod apertures aperture is the least, the choked flow adding both pressure adjustable check valves is made
With so that in left cavity, hydraulic pressure promotes spring diaphragm and seesaw push rod to the right more than the hydraulic pressure in right cavity, the pressure differential of generation
Mobile.Power is conducted on & off switch by lever principle by seesaw push rod again, the bottom pressure switches key of seesaw push rod, power supply
Derailing switch energising work.When water inlet pipe hydraulic pressure is less than 0.03MPa, although hydraulic pressure is more than hydraulic pressure in right cavity in left cavity, but
The pressure differential produced is insufficient to promote spring diaphragm own resilience and switch making a concerted effort to the feedback force of seesaw push rod.Power supply is opened
Close the work of device no power.When water inlet pressure big the most to a certain extent time, adjustable one-way valve work makes the hydraulic pressure of left cavity release
A part, it is excessive and produce fracture phenomena that protection spring diaphragm is unlikely to stress.
Concrete to set product additionally by the action force regulating the first pod apertures pore size and pressure adjustable check valve
Startup pressure.Therefore the startup pressure of adjustable product so that low hydraulic pressure area could be used that.When outlet pipe is blocked, ice
Freeze, when connecing choked flow part, owing to left cavity, right cavity, pedestal are all intercommunications, the hydraulic pressure in pedestal produces because of outer draining
Raw low pressure, the hydraulic pressure in the most left cavity and right cavity is all equal.Left cavity and right cavity can not produce differential water pressures, now
Switch does not works.When the water in left cavity and right cavity is all frozen, spring diaphragm is frozen the most in the lump, now
Power switching device no power works.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and modification, these improve and modification
Also should be regarded as protection scope of the present invention.
