Potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is：In order to overcome traditional automatic shutoff protection device water cut-off protection
Function is poor, and switching gas speed is slower, it is impossible to meets and uses, there is certain potential safety hazard, there is provided one kind is from dynamic circuit breaker
Water conservation device.
This utility model solves the technical scheme adopted by its technical problem：A kind of automatic shutoff protection device, including
Mounting seat, inlet pipeline, outlet pipeline, suppress bucket, two-way valve and the lever being rotatably installed in mounting seat, the water inlet pipe
The branch road formed between road and the outlet pipeline flows through the rodless cavity for suppressing bucket, it is described suppress bucket be fixedly mounted on it is described
In mounting seat, it is described suppress suppress plate, the outer wall for suppressing plate and the inwall for suppressing bucket
Support bar be installed with plate in laminating, described being suppressed, and the support bar is hinged with one end of the lever, the two-way valve peace
It is mounted in the mounting seat, the valve rod in the two-way valve is hinged with the other end of the lever.
In order to control the numerical range of hydraulic pressure, it is described suppress plate and suppress fixedly mount flexible unit between lid on bucket
Part.
When suppressing plate and continuing upward rising, the valve rod in two-way valve by lever pushing continue downwards, when valve rod it is pushed
During to lower dead center, suppress plate and throw away and continue upward rising, in order to protect two-way valve without damage, the two-way valve bottom and the peace
Fixedly mount between dress seat and have elastic component.
In order to simplify integral installation structure of the present utility model, the flexible member is spring.
In order to the rise and fall for ensureing lever two ends pin joint it is highly consistent, and suppress plate with two-way valve valve rod it is upper
What is risen and decline is highly consistent, and the middle position of the lever is rotated with the mounting seat and is connected.
The beneficial effects of the utility model are:Automatic shutoff protection device of the present utility model, using being rotatably installed in peace
Lever valve rod of the connect setting in the support bar and two-way valve suppressed in bucket respectively on dress seat, when suppressing the hydraulic pressure in bucket
During more than 0.15MPa, plate being suppressed along the inwall upward sliding for suppressing bucket, driving support bar to move up, support bar promotes thick stick
Bar is rotated, and one end that lever is connected with support bar rises, and the one end being connected with valve rod is declined, and promotes the valve rod of two-way valve downwards,
Two-way valve works, and the air inlet on two-way valve is communicated with gas outlet, realizes supply；When hydraulic pressure is less than 0.07MPa or closes water route
After ball valve, two-way valve homing, air inlet and gas outlet disconnect, and realize dying, so as to realize automatic shutoff defencive function, and
The speed of switching gas, the effect of water cut-off protection be preferable, it is to avoid potential safety hazard.
