Description
Technical field
The present invention relates to draining valve technical field, the flow adjusting structure of draining valve is referred in particular to.
Background technology
In the prior art, common draining valve includes valve body, is installed in valve body and realizes half row's draining and the full row of row's draining
Water assembly, the drain assembly include half row's button, arrange button, drive rod, half row's keg float, whole row float bucket, inner core tube and water shutoff entirely
Piece；Drive rod is pivoted in valve body, and drive rod one end is connected with inner core tube upper end, the drive rod other end and half row's button and
Full row press key connection, and the row's button of pressing half or full row's button drive drive rod linkage inner core tube difference stroke motion, under inner core tube
The water sealing slice that the discharge outlet of end installation and valve body coordinates；Half row's spacing preiection is formed in inner core tube and arranges spacing preiection entirely, it is right
Ying Di, accordingly, the row's support of setting half is interlocked with half row's keg float, half arranges the row's fulcrum of setting half on support, is interlocked with whole row float bucket
Full row's support is set, and complete arrange sets full row's fulcrum on support.
The row's button of pressing half, drives inner core tube to be lifted up by drive rod, and being resisted against half row to half row's spacing preiection floats
On half row's fulcrum that bucket interlocks, now inner core tube is limited, and water sealing slice is raised, and realizes bath.During bath, the water level in water tank
Decline, and valve body lower portion sets leaking hole, the water level in valve body declines therewith, at the water level decreasing in valve body to half row's keg float
When, half arranges keg float loss of buoyance and interlocks the deflection of half row's fulcrum under gravity, i.e., is opened outside half row's fulcrum, inner core tube lose to
Resetted by falling, water sealing slice is fallen after rise to discharge outlet, completes half row's bath.
The full row's button of pressing, drives inner core tube to be lifted up by drive rod, and it is floating to be resisted against full row to full row's spacing preiection
On full row's fulcrum of bucket, now inner core tube is limited, and water sealing slice is raised, and realizes bath.During bath, under the water level in water tank
Drop, and valve body lower portion sets leaking hole, the water level in valve body declines therewith, at the water level decreasing in valve body to whole row float bucket
When, whole row float bucket loss of buoyance and interlock full row's fulcrum deflection under gravity, i.e., opened entirely outside row's fulcrum, inner core tube lose to
Resetted by falling, water sealing slice is fallen after rise to discharge outlet, completes full row's bath.
However, the defects of draining valve, is：The displacement of the leaking hole of valve body is fixed, and can not adjust the leakage of the valve body
The displacement in water hole so that it is fixed that draining valve half, which arranges displacement and full row's displacement, and displacement is either excessive or very few,
Accurate draining can not be realized.
For the displacement of the leaking hole of regulation valve body, Authorization Notice No. is that the U of CN 205935105 disclose a kind of draining valve stream
Adjustment structure is measured, including draining valve body and adjustment sheet, draining valve body are provided with rhone, adjustment sheet is installed in rhone
And can be slided up and down along rhone, adjustment sheet is provided with the position point for being capable of elastic deformation, and one determines for adjusting this
It is capable of the slotting key of elastic deformation or non-elastically deformable in position position.Realize that displacement is adjusted by sliding up and down adjustment sheet, so
And have a disadvantage in that：
