Abstract
The utility model relates to a floating ball type water level control valve, which comprises a floating ball, and a soft chain, wherein, the floating ball is connected with a sealing valve core through the soft chain. The utility model is characterized in that a valve chamber is arranged in a valve body, a lateral flow baffle plate is arranged at the middle part of the valve chamber, the valve chamber is divided into an upper valve chamber and a lower valve chamber by the lateral flow baffle plate, the sealing valve core is arranged in the upper valve chamber, and a limiting flow valve core is arranged in the lower valve chamber. The utility model can reliably control water level, adopts the mode of lateral flow of the baffle plate, double guide, one-way flow limiting, and soft sealing of a rubber pad, causes the action of the floating ball valve precise and not clamp, and effectively increases the sealing reliability.
Description
[technical field]
The utility model relates to a kind of float-ball type fluid level control valve, is applicable to the single tube liquid level control of all kinds of casings of liquid up and down.
[background technique]
The casing of storing liquid, general level detection electromechanical control and the traditional forms such as float valve control of adopting of liquid level control.Level detection Mechatronic control system complex structure, the cost height, in case go wrong, maintenance is trouble, difficulty especially, if having a power failure, just can't realize the control of liquid level; And traditional float valve control need connect the function that one-way valve could be realized liquid about the single tube in addition, be not suitable for closed container again, and, add that liquid stream is bigger to the impact of spool because the location of spool is unreasonable, make spool very easily stuck, cause control valve malfunctioning and can't carry out the control of liquid level.Also exist simultaneously complex structure, cost problem of higher.
[summary of the invention]
The purpose of this utility model is the deficiency at the said goods, propose a kind of simple in structure, action accurately, be difficult for stuck float-ball type fluid level control valve.
The purpose of this utility model is achieved in that
A kind of float-ball type fluid level control valve, comprise ball float, soft chain, ball float is connected with sealed valve core by soft chain, it is characterized in that being provided with in the valve body valve pocket, is provided with the effluent baffle plate at the middle part of valve pocket, the effluent baffle plate is divided into uuper valve chamber with valve pocket, lower valve chamber, sealed valve core are contained in the uuper valve chamber, and the current limliting spool is contained in the lower valve chamber.
Aforesaid a kind of float-ball type fluid level control valve is characterized in that being provided with the guiding gusset at the internal layer of valve pocket, is provided with guide ring in the upper end of valve body, and valve core cooperates one group of guiding of formation with the guiding gusset, and guide rod cooperates another group guiding of formation with guide ring.Be provided with the by-pass between the chamber, be provided with positive stop lug boss in the bottom of baffle plate.
Aforesaid a kind of float-ball type fluid level control valve, the surface configuration that it is characterized in that sealing gasket is the sphere or the conical surface,
The utility model can be controlled liquid level reliably, simple in structure, owing to adopted baffle plate effluent, two guiding, unidirectional current limliting and rubber pad soft seal mode, make the float valve action accurately, can be not stuck, improved the reliability of sealing effectively, in the working life of simultaneously also improving valve body, reduced the manufacture cost of fluid level control valve.Be applicable to all non-sealing and closed containers.
Be further described below by embodiment and accompanying drawing.
Fig. 1 is an a kind of embodiment's of the present utility model structural representation.
[embodiment]
Referring to Fig. 1: a kind of float-ball type fluid level control valve, comprise ball float 1, ball float 1 is connected with soft chain 2, and soft chain 2 links together by connecting ring 3 and sealed valve core 4, and sealed valve core 4 is contained in the valve body 5, is provided with valve pocket 6 in the valve body.Be provided with effluent baffle plate 7 at the middle part of valve pocket 6, valve pocket 6 is divided into uuper valve chamber 8, lower valve chamber 9 can only move sealed valve core 4 in uuper valve chamber 8, then be provided with current limliting spool 10 in lower valve chamber 9.
On valve body 5, be provided with feed pathway 11 and liquid outlet channel 12, in valve body 5, be provided with smooth seal face 13, be provided with guiding gusset 14, be provided with guide ring 15 in the upper end of valve body 5 at the internal layer of valve pocket 6.
Sealed valve core 4 is made of valve core 16, the sealing gasket 17 and the guide rod 18 that are contained on the valve core 16, the surface configuration of sealing gasket 17 can be the sphere or the conical surface, corresponding with smooth seal face 13, make it when moving on the sealed valve core 4, when sealing gasket 17 contacts with smooth seal face 13, can cutting off passing through of liquid stream.The valve core 16 of sealed valve core 4 forms one group of guiding with guiding gusset 15, and guide rod 18 forms another group guiding with guide ring 15.Can guarantee that sealed valve core 4 can be not stuck when mobile in valve body 5.
When the utility model is installed in the container bottom, when liquid enters the lower valve chamber 9 of valve body 5 by feed pathway 11, as enter the excessive current limliting spool 10 that then promotes of fluid pressure and move up, when current limliting spool 10 is pulled to boss 21 bottoms, boss 21 blocks the by-pass 20 of current limliting spool 18, liquid can only flow through from the middle aperture 19 of current limliting spool 10, has reduced the fluid flow by valve pocket 6, thereby has also reduced the impact of liquid stream to spool.In liquid entered valve pocket 6, baffle plate 7 barrier liquids can only separately pass through from side, had further reduced the impact of liquid stream to spool; Little as pressure, then current limliting spool 10 is motionless in the bottom, and liquid flows through from middle aperture and by-pass.Because the effect of baffle plate 7, liquid stream can be greatly not too to the impact of spool.When liquid stream enters container from liquid outlet channel 12, liquid level rises in the container, and ball float 1 is along with liquid level rises, and when soft chain 2 was stretching, pulling sealed valve core 4 moved up, and rubber gasket 17 and smooth seal face 13 is compressed form sealing, and valve cuts out automatically.When needs flow out liquid from container, sealed valve core 4 is moved down, current limliting spool 18 also is in the bottom, and liquid can flow out with bigger flow, forms unidirectional current limliting.
Sealed valve core 11 is being controlled the amplitude of fluctuation of ball float 1-valve rod 4-sealed valve core 11 with cylindrical body 13 and valve rod 4 with two guiding that guide ring 10 forms.Add the effect of current limliting spool 18 and plate washer 16, it is stuck by valve body 5 that sealed valve core 4 is difficult for.
