Abstract
The utility model relates to a float valve, which is characterized by comprising a valve body with a valve gate, a valve core, a shifting level driving the valve core to move, and a floating ball driving the shifting level to swing. The valve body is a tube. The valve gate is arranged on one end of the tube valve body. The valve core consists of a valve core body and a sliding block. The sliding block consists of a sliding block body, and three or more rods arranged along the periphery of the sliding block body. The middle part of the sliding block body is provided with a groove. The shiftinglevel which passes through the side wall of the tube valve body and is rotatably arranged on the lateral wall of the tube valve body is inserted into the groove in the middle part of the sliding blockbody. Compared with the prior art, the utility model has the advantage that when the water in the water pool is over the setting water level, and the valve gate can be reliably controlled to open todrain until the water level is recovered to the setting water level.
Description
Technical field:
The utility model relates to a kind of water valve, particularly a kind of float valve.
Background technique:
The effect of existing float valve is when water level in water pool is lower than designated water level, and ball float falls, and valve is opened, and adds water toward the pond, till water level reaches designated water level.When this kind float valve can only control water level descends, in the pond, add water, and can not control the requirement that discharge water of tank water when full, in fact, in a lot of occasions (as electricity power enterprise), often need when expire designated water level, tank water need open valve and discharge water, at present, also there is not a kind of float valve technology that can satisfy above-mentioned requirements reliably.
Summary of the invention:
When goal of the invention of the present utility model was to provide a kind of tank water to expire designated water level, control valve was opened and is discharged water reliably, the float valve till water level returns to designated water level.
The utility model is to realize like this, comprise the driving lever that the valve body, spool, the drive spool that have valve move, the ball float that drives the driving lever swing, valve body is a pipe, valve is arranged on a wherein end of pipe valve body, spool is made of valve core, slide block, the bar more than three or three that slide block is provided with by slide body, around the slide body outside constitutes, slide body middle part is provided with groove, passes the driving lever that pipe body wall and rotation be arranged on the pipe valve body outer side wall and injects in the groove at slide body middle part.During use, the present invention is fixed in the pond below the designated water level in pond, its valve export links to each other with the outfall in pond, when water level in water pool is positioned at designated water level when following, ball float is under the effect of self gravitation, fall, drive the driving lever swing, driving lever then promotes spool and moves toward the valve direction, with valve closing, when water level in water pool exceeded designated water level, ball float moved under the promotion of water buoyancy, drove the driving lever swing, driving lever then promotes spool and moves in the other direction toward valve, with valve open, the water in pond is drained outward, ball float falls with drawdown, drop to designated water level until water level in water pool, ball float drives the driving lever swing, and driving lever then promotes spool and moves toward the valve direction, till valve closing.Employing is provided with the bar more than three or three all around along the slide body outside, make the internal diameter of the diameter of slide body much smaller than the pipe valve body, and making has enough spaces to allow water pass through between pipe valve body and slide body.The present invention can also be connected water intake of the present invention except being used for the control of body water level in water pool with other pond, control the draining situation in other pond according to the situation of body water level in water pool.
In order to make smoothly,, the bar more than three all is set around the slide body outside at the slide body two ends along axis straight line motion in the pipe valve body.
Move in order to make driving lever promote spool smoothly, the groove at slide body middle part is the groove that runs through slide body, and the madial wall below the pipe valve body of corresponding groove is provided with the driving lever guide groove, passes the driving lever end of groove and swings along the driving lever guide groove.Like this, driving lever just can double swerve under the restriction of articulating point and driving lever guide groove, has guaranteed that it promotes spool smoothly and moves.
For the solid matter in the anti-sealing stops up the driving lever guide groove, the driving lever guide groove is made of two symmetrical flanges on the madial wall that is arranged on below the pipe valve body, and the front end of flange leaves the pipe valve end.Like this, even there is solid matter to enter the driving lever guide groove with water, these solid matters also can leave from the gap between the valve of the front end of flange and pipe valve end by solid matter.
Both sides in the motion medial axis of the corresponding slide body of driving lever are provided with projection.Like this, driving lever is located by the motion medial axis that projection acts on slide body, has guaranteed that the motion of slide body is smooth and easy.
Driving lever is made of main driving lever and the ball float adjustable lever that is hinged on the main driving lever, and the face of being articulated and connected of main driving lever and ball float adjustable lever is the flank of tooth, hingedly fixes by screw, nut.
The utility model compared with the prior art, when having tank water and expiring designated water level, control valve is opened and is discharged water reliably, the advantage till water level returns to designated water level.
