The utility model discloses a kind of float valve that can automatically close.Float valve comprises valve body, spool, intermediate bar, screw rod, spring and ball float, the closed at both ends of valve body, its water intake and water outlet are all arranged on the both sides of valve body, in valve body, be provided with waterproof block, in spool setting and valve body, spring is positioned in valve body, and spool is between spring and block, the outer wall of valve body is provided with two supporting bases, screw rod is fixed on two supporting bases, and screw rod can rotate relative to supporting base, and one end of intermediate bar is sleeved on screw rod, the other end and the spool of intermediate bar are fixed, and valve body is provided with the opening moving for intermediate bar.The utility model float valve utilizes ball float to drive bolt rotary, bolt rotary drives intermediate bar to move left and right, and intermediate bar band movable valve plug moves left and right, thereby opens or closes float valve, simple in structure and highly sensitive, can also avoid waste unnecessary in the time that float valve breaks down simultaneously.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of float valve.
Background technique
Float valve is by the height of ball float perception liquid level and then the unlatching of control valve and closure.At present conventional float valve structure is comparatively complicated, and cost of production is higher, and valve is sensitive not with the variation of water level, and repair demolition is simultaneously also quite inconvenient.Therefore in the urgent need to a kind of float valve of simple in structure and low in cost, after common float valve breaks down, can not close its valve, when casing water completely after, float valve, always in open mode, can continue, toward casing inner water-supply, to cause the waste of water resources.
Model utility content
The technical problems to be solved in the utility model be simple in structure, in the time that float valve breaks down the automatic float valve in closed condition.
For addressing the above problem, the utility model provides a kind of float valve that can automatically close, described float valve comprises valve body, spool, intermediate bar, screw rod, spring and ball float, the closed at both ends of described valve body, its water intake and water outlet are all arranged on the both sides of described valve body, in described valve body, be provided with waterproof block, in described spool setting and described valve body, described spring is positioned in described valve body, and described spool is between described spring and described block, the outer wall of described valve body is provided with two supporting bases, described screw rod is fixed on described two supporting bases, and described screw rod can rotate relative to described supporting base, one end of described intermediate bar is sleeved on described screw rod, the other end of described intermediate bar and described spool are fixed, described valve body is provided with the opening moving for intermediate bar.
Further, described intermediate bar comprises collar, vertical pull bar and the sleeve pipe with screw, described collar interts on described block, and one end of described horizon bar and described spool are fixed, the other end of described collar is fixed with one end of described vertical pull bar, described vertical pull bar is positioned at described opening, and one end of described vertical pull bar and described sleeve pipe are fixed, and described casing pipe sleeve is contained on described screw rod.
Further, described supporting base is provided with two bearings, and described screw rod is fixed on described supporting base by described bearing.
Further, described screw rod is L-shaped, and described screw rod comprises rotating shaft and connecting rod, and described connecting rod is fixed in described rotating shaft, and described rotating shaft is fixed on described supporting base, and one end of described connecting rod and described ball float are fixed.
The utility model float valve utilizes ball float to drive bolt rotary, and bolt rotary drives intermediate bar to move left and right, and intermediate bar band movable valve plug moves left and right, thereby opens or closes float valve, simple in structure and highly sensitive; When described intermediate bar is not subject to described screw rod spacing, the described sealing block of promotion of described spring moves, and promotes intermediate bar simultaneously and moves, and described intermediate bar and described spool are fixed, and therefore spool can move to water outlet.
Brief description of the drawings
Fig. 1 is the structural representation of the preferred embodiments of the utility model float valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the preferred embodiments of the utility model float valve comprises valve body 1, spool 2, intermediate bar 3, screw rod 4, spring 6 and ball float 5, the closed at both ends of described valve body 1, its water intake 13 and water outlet 12 are all arranged on the both sides of described valve body 1, in described valve body 1, be provided with waterproof block 7, in described spool 2 settings and described valve body 1, described spring 6 is positioned in described valve body 1, and described spool 2 is between described spring 6 and described block 7, the outer wall of described valve body 1 is provided with two supporting bases 11, described screw rod 4 is fixed on described two supporting bases 41, and described screw rod 4 can rotate relative to described supporting base 41, one end of described intermediate bar 3 is sleeved on described screw rod 4, the other end of described intermediate bar 3 and described spool 2 are fixing, described valve body 1 is provided with the opening moving for intermediate bar 3, can flow out from opening by anti-sealing.
Described intermediate bar 3 comprises collar 33, vertical pull bar 32 and the sleeve pipe with screw 31, described collar 33 interts on described block 7, and one end of described horizon bar 33 and described spool 2 are fixing, the other end of described collar 33 is fixed with one end of described vertical pull bar 32, described vertical pull bar 32 is positioned at described opening, one end of described vertical pull bar 32 and described sleeve pipe 31 are fixing, and described sleeve pipe 31 is sleeved on described screw rod 4.
Described supporting base 11 is provided with two bearings, and described screw rod 4 is fixed on described supporting base 11 by described bearing.
Described screw rod 4 is L-shaped, and described screw rod 4 comprises rotating shaft 41 and connecting rod 42, and described connecting rod 42 is fixed in described rotating shaft 41, and described rotating shaft 41 is fixed on described supporting base 11, and one end of described connecting rod 42 and described ball float 5 are fixing.
The utility model float valve utilizes ball float 5 to drive screw rod 4 to rotate, and screw rod 4 rotates and drives intermediate bar 3 to move left and right, and intermediate bar 3 is with movable valve plug 2 to move left and right, thereby opens or closes ball float 5 valves.When described intermediate bar 3 is not subject to described screw rod 4 spacing, the described spool of promotion of described spring 6 moves 2 and moves to water outlet or water intake, and can avoid unnecessary waste.
