Example is used to illustrate 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 using differential water pressures controlling switch power on/off, including pedestal 1, it is arranged on pedestal 1
Water inlet pipe 2 in side wall and the outlet pipe 3 for being arranged on the top of pedestal 1, the water inlet pipe 2 are provided with valve 4, the pedestal 1
Inside be provided with the fixed seat 5 that connect with water inlet pipe 2, the inside of fixed seat 5 provided with the hydraulic pressure switch storehouse 6 connected with water inlet pipe 2,
Top end inside 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
It is fixed, the first pod apertures 9 and the second pod apertures 10 are respectively equipped with the left and right sides wall in hydraulic pressure switch storehouse 6, inside hydraulic pressure switch storehouse 6
Provided with the spring diaphragm 11 inserted by the bottom of fixed seat 5, the bottom of spring diaphragm 11 passes through the connecting valve support of seesaw push rod 12
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 the bottom of seesaw push rod 12
The on ＆ off switch 15 of contact.
The structure using differential water pressures controlling switch power on/off of the present invention, in the fixed seat 5 on the right side of the spring diaphragm 11
Portion is provided with boss 16 integrally formed with fixed seat 5.
The structure using differential water pressures controlling switch power on/off of the present invention, the spring diaphragm 11 is by hydraulic pressure switch storehouse 6
Inside is divided into left chamber body 17 and right chamber body 18, and left chamber body 17 and right chamber body 18 pass through the first pod apertures 9 and the second pod apertures respectively
10 with the connects with the internal cavities of pedestal 1.
The structure using differential water pressures controlling switch power on/off of the present invention, the inside of the spring diaphragm 11, which is inlaid with, plays
The door shape support member 19 of supporting role.
The structure using differential water pressures controlling switch power on/off of the present invention, the cross section of the seesaw push rod 12 is L-shaped knot
Structure, the top of seesaw push rod 12 pass through the inside that the spring diaphragm 11 is plugged on after switch bracket 13.
The structure using differential water pressures controlling switch power on/off of the present invention, the top end face of the switch bracket 13 be provided with
The fixing groove 20 that the bottom face of spring diaphragm 11 is engaged, the bottom face of spring diaphragm 11, which is fixed in fixing groove 20, realizes that sealing is made
With.
The structure using differential water pressures controlling switch power on/off of the present invention, the switch bracket 13 are fixed on by screw 21
On the bottom face of fixed seat 5.
When specifically used, Natural Water is entered the structure using differential water pressures controlling switch power on/off of the present invention by water inlet pipe
Enter into left chamber body, the water in left chamber body is entered in pedestal by the first pod apertures and pressure adjustable check valve, in pedestal
Water enters right chamber body by the second pod apertures, while the water in pedestal is discharged outside by outlet pipe.Due to the water in pedestal
Directly discharged through outlet pipe, therefore the hydraulic pressure in pedestal is extremely low, the hydraulic pressure in right chamber body is equal to the hydraulic pressure in pedestal.Work as water inlet
When pipe hydraulic pressure is more than 0.03MPa, due to the first pod apertures aperture very little, along with the choked flow of both pressure adjustable check valves is made
With so that hydraulic pressure is more than the hydraulic pressure in right chamber body in left chamber body, and caused pressure differential push the spring diaphragm and seesaw push rod are to the right
It is 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 energization work.When water inlet pipe hydraulic pressure is less than 0.03MPa, although hydraulic pressure is more than hydraulic pressure in right chamber body in left chamber body,
Caused pressure differential is insufficient to push the spring diaphragm own resilience and switched make 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 it is big to a certain extent when, adjustable one-way valve, which works, causes the hydraulic pressure of left chamber body to release
A part, it is excessive and produce fracture phenomena that protection spring diaphragm is unlikely to stress.
Operation force additionally by the first pod apertures pore size of regulation and pressure adjustable check valve is specific to set product
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
When freezing, connecing choked flow part, because left chamber body, right chamber body, pedestal are all intercommunications, the hydraulic pressure in pedestal does not produce because of outer draining
Low pressure is given birth to, now the hydraulic pressure in left chamber body and right chamber body is all equal.Left chamber body and right chamber body can not produce differential water pressures, now
Switch does not work.When the water in left chamber body and right chamber body is all frozen, spring diaphragm is also frozen in the lump, now
Power switching device no power works.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and modification can also be made, these improvement and modification
Also it should be regarded as protection scope of the present invention.
