It is engaged on 6 bottom end face of flap embedded with sealing ring 11,11 bottom surface of sealing ring with segmentation block 3.
The operation principle of this ball-cock assembly is as follows：
1：The built-in ball-cock assembly of service position is mounted in pipe end, when pipe-line system starts normal water supply, floating ball
In free state, block valve 4 is to open.Fluid stream in pipeline to built-in ball-cock assembly, by from fluid pressed by flap 6
Power is caused to move upwardly, and until fully open position, at this moment a part of fluid flows directly into valve from valve inlet by road in valve body 1
Door exports to pond, and another part fluid flows to flap 6 by valve body 1, valve deck 2 is flowed by 6 through-hole of flap, using valve deck
Hole on 2 flows through block valve 4 into pond, and pipe-line system supplies water to pond.In the process, when fluid passes through 1 inner cavity of main valve body
For full-bore, without the guiding trestle in traditional ball-cock assembly, area of passage is increased in this way, improves discharge coefficient, is reduced
Head loss.Meanwhile fluid flows to block valve 4 by 6 through-hole of flap from valve body 1 and exports, and forms an inner passage, thus
The outer configuration bypass line in traditional ball-cock assembly is avoided, prevented outer tube leakage and is collided in transportational process middle external tube
And it generates damaged.
2：State of cutting off the water supply pipeline is continuing into pond water supply process, and pond liquid level constantly rises, when rising to certain height
When spending (this can highly be set), floating ball 5 is lifted by water, and floating ball 5, which lifts, pushes block valve 4 to close, and flows into valve valve at this time
The fluid of 6 upper end of valve can not be discharged from block valve 4, since the area of 6 upper end of flap is more than the area of 6 lower end of flap, on flap 6
The pressure at end starts to build up, and when the pressure of 6 upper end of flap is more than 6 time end pressures of flap, Fluid pressure promotion flap 6 is to moving down
It is dynamic, it is bonded, is formed until closing completely until with 1 sealing position of valve body, pipe-line system stops supplying water to pond at this time.This process
Middle cylinder sleeve 8 also has valve deck 2 to form piston cylinder operator with flap 6, and flap 6 transmits Fluid pressure, relative to ball-cock assembly diaphragm type knot
Structure, this piston cylinder operator, parts are few, can not only save cost, and without diaphragm, and diaphragm is that rubber is rapid wear
Part, it is easy to aging, it needs to replace often.
3：Open stage when pond water constantly export persistently reduce when, pond position decline, floating ball 5 due to dead weight, fall down,
Block valve 4 is pushed to open in this way, flap 6 squeezes out the water of 6 upper end of flap from block valve 4, by the thrust of fluid on flap 6
The pressure at end reduces, and when being less than the pressure of 6 lower end of flap, flap 6 moves up, until main valve standard-sized sheet, pipeline system at this time
System supplies water by main valve to pond.Flap 6 is fitted closely with cylinder sleeve 8 during this, is moved back and forth freely, is not needed to valve rod to lead
To saving valve rod and guiding trestle in this way, reduce the manufacture cost of valve.
