Abstract
The utility model relates to a normally closed water level floating ball valve, comprising a valve body, a valve core and a floating ball. The valve body is provided with a water inlet and a water outlet. The valve core is T shaped, and the water stop face of the valve core in the valve body faces downwards. The normally closed water level floating ball valve is not easy to leak water even if the hydraulic pressure is too high. The normally closed water level floating ball valve is used in the high level cisterns such as a water tank, a water tower, a pond, etc.
Description
One, affiliated technical field
The utility model relates to a kind of valve, refers in particular to a kind of Water level ball float that is used in high water level resevoir such as water tank, water tower, pond etc.
Two, background technique
At present, the Water level ball float that is used in high water level resevoir such as water tank, water tower, the pond is open in usual, and valve body is made by copper, stainless steel, plastic or other material.High water level resevoir such as water tank, water tower, pond etc., be mainly the not high place of insufficient water sources or hydraulic pressure and be provided with, when hydraulic pressure is not enough, generally use the water pump pressurized water supply, when hydraulic pressure is enough in the regular hour, close automatically after water inlet is full of the high water level resevoir automatically.The working principle of Water level ball float open in usual is as follows: when water level reached designated water level, ball float rose and to make spool block water intake to carry out sealing; When water level one decline, ball float decline drives spool and leaves the sealing face, and water intake intakes to come out from water outlet at once.They have following defective: if hydraulic pressure is too high or sealing face processing is inaccurate, spool just is difficult to block water intake, causes into that water too much overflows the high water level resevoir, not only wastes precious water resource and electric energy, and has influenced the working life of water pump.Chinese patent once disclosed a kind of " Water level ball float " (ZL98221286.0, open day 1999.10.20), it includes valve body, valve gap, spool, valve rod, ball float, being characterized as valve gap is fastened on the valve body, spool is arranged in body cavity and is connected in the valve rod lower end, with the valve rod interlock, valve rod passes the valve gap center and links to each other with ball float, and the outlet outer end that valve rod passes valve gap is provided with the sheath of being with spring.It belongs to Water level ball float open in usual.
Three, model utility content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of Normally closed type Water level ball float is provided, too high its also antileaking of hydraulic pressure.
For achieving the above object, the solution that the utility model is taked is: a kind of Normally closed type Water level ball float, include valve body, spool, ball float, and valve body has water intake and water outlet, and spool is the T font, and the sealing of spool faces down in valve body.
Its working principle is as follows: when water level reached the high water level of setting, ball float rose to horizontal position, and spool falls naturally, and its falling speed is faster under the effect of hydraulic pressure, and its sealing face is blocked water outlet and carried out sealing, although how high hydraulic pressure is, can not leak; When drawdown during to the low water level set, the gravity of ball float makes spool upwards, its sealing face leaves water outlet, the water of coming in from water intake comes out from water outlet, water enters in the high water level resevoir, and water level rises until making ball float rise to certain position to the high water level of setting, and spool falls naturally, its falling speed is faster under the effect of hydraulic pressure, and its sealing face is blocked water outlet again and carried out sealing.During not to the low water level set, spool is often blocked water outlet and is carried out sealing, therefore is referred to as the Normally closed type Water level ball float at water level.At water level one during to the low water level set, water inlet at once is up to high water level, disposable finishing, and water quality is fresh.
Four, description of drawings
Fig. 1 is the structural representation of present embodiment.
Among the figure: 1, valve body, 2, spool, 3, water intake, 4, water outlet, 5, the sealing face, 6, connecting rod, 7, main ball float, 8, secondary ball float, 9, the length-adjustable line, 10, piston.
Five, embodiment
Referring to Fig. 1, a kind of Normally closed type Water level ball float includes valve body 1, spool 2, ball float, and valve body 1 has water intake 3 and water outlet 4, and spool 2 is the T font, and the sealing face 5 of spool 2 down in valve body 1.
Referring to Fig. 1, described ball float is made of main ball float 7 and secondary ball float 8, and main ball float 7 is connected by length-adjustable line 9 with secondary ball float 8.The gap of high water level and low water level is regulated in the selection of the length by length-adjustable line 9.When arriving high water level, main ball float 7 and secondary ball float 8 are in the same level position, and valve is closed at once.
Referring to Fig. 1, a piston 10 is equipped with in valve body 1 bottom, this piston 10 and spool 2 interlocks, and piston 10 is connected by connecting rod 6 with main ball float 7.The gravity of main ball float 7 and secondary ball float 8 acts on spool 2 by connecting rod 6 and piston 10, and when main ball float 7 and secondary ball float 8 were in same horizontal position, spool 2 fallings speed were faster, once not intaking to high water level, once accomplish water inlet easily to low water level.
Referring to Fig. 1, main ball float 7 is identical with secondary ball float 8, helps gravity and calculates and produce in batches.
Referring to Fig. 1, secondary ball float 8 is filled water, and main ball float 7 half water of dress make secondary ball float 8 overall weight greater than main ball float 7.
Even under high hydraulic pressure situation the also watertight advantage, it is many to double than general Water level ball float linear flow rate open in usual, has reduced water-aspirator pressure on the one hand, increases the service life, on the other hand power saving when arriving high water level for the utility model.
