Description
Technical field
The utility model belongs to valve technology field, relates to a kind of float valve.
Background technique
At some automatic feed liquor bodies with need generally all to need to use float valve in the facility of fixing liquid level.As the float valve that uses on water tank, water tower and the water closet mainly is to utilize buoyancy of water to control, and when liquid level descended, float valve was opened liquid entering hole automatically, and along with the rising of liquid level, float valve can be closed liquid entering hole again automatically.
The disclosed a kind of float valve of Chinese patent literature [publication number: CN2623986] for example, comprise valve body, lever and ball float with import and outlet, be provided with spool in valve body, lever is the hinge type swing rod structure, one end of lever heads on the spool in the valve body, and the other end links to each other with ball float.When water level reduced, ball float was along with drawdown is opened import by the lever drives spool, and water just enters in the liquid storage tank, and when water level raise, ball float blocked import along with water level rises by the lever drives spool, and water just stops to flow into liquid storage tank.The float valve of this structure is because lever is changeless with horizontal position after ball float is connected, following problem often appears in the installation and operation process like this: when the pressure of water obviously raises or spool move when ineffective because of wearing and tearing, because the moment of leverage on spool is limited, lever is not enough to drive spool import is closed, liquid in the liquid storage tank is exceeded set liquid level and overflow, common solution is with the lever bending, makes the liquid level that float valve reaches to be needed.Existing other technological scheme also exists similar problem.
Summary of the invention
The purpose of this utility model is at existing existing the problems referred to above, and the float valve that a kind of effectively throttle down, installation and operation are convenient, sealing reliability is high is provided.
The purpose of this utility model can realize by following technical proposal: a kind of float valve, comprise valve body, valve rod and be arranged on the interior spool of valve body, the inner and the spool of valve rod are connected, the outer end of valve rod passes valve body, it is characterized in that, a hinged connecting rod on the described valve body, one end of connecting rod has a prong, the outer end of above-mentioned valve rod is stuck in the prong, the other end of connecting rod is connected with ball lever, and the joint of connecting rod and ball lever is provided with the controlling mechanism that can regulate angle angle between connecting rod and the ball lever.
This float valve is arranged on the intake pipe of water tower, water tank or water closet.Wherein have water intake and water outlet on the valve body, at first the water intake of valve body is communicated with intake pipe.A hinged connecting rod on the valve body, connecting rod can be swung on valve body like this.One end of connecting rod has a prong, and the outer end of valve rod is stuck in the prong in addition, and when connecting rod swing, this prong can drive valve rod and slide up and down like this, slides up and down the opening and closing that realize float valve thereby drive spool.The other end of connecting rod is connected with ball lever, also is connected with ball float at the other end of ball lever, by this ball float can control water level height.Can both work effectively reliably under the situation of different intake pressures in order to make float valve, be provided with the controlling mechanism that to regulate angle angle between connecting rod and the ball lever in the joint of connecting rod and ball lever, by regulating angle angle between connecting rod and the ball lever, make float valve reach required liquid level, the pressure of water that is to say and adjusted moment on the spool that acts on, even more also can effectively be closed like this.
When water level reduced, drivening rod was to lower swing thereby ball float falls, and an end yoke mouth of connecting rod drives valve rod again and upwards slides, thereby makes spool open the water inlet, and water just enters in the liquid storage tank.After water level rose, buoyancy held up ball float, and the ball lever drivening rod is swing upwards, thereby drove valve rod to lower slider, and spool is just blocked the water inlet like this, made it can't water flowing.
In above-mentioned float valve, described controlling mechanism comprises the binding block that is arranged on the connecting rod, is arranged on binding block and screw on the ball lever, and two above-mentioned binding blocks link together by screw.Wherein two binding blocks are linked together the convenient like this angle of adjusting between connecting rod and the ball lever by screw.
In above-mentioned float valve, described two binding block places of mutually combining are provided with intermeshing several latches, and described latch distributes ringwise, and described latch is a conical tooth.Under the effect by two intermeshing several latches of binding block, make firm the linking together and can not occur sliding of connecting rod and ball lever.
In above-mentioned float valve, have a positioning recess on the described valve rod, the prong of above-mentioned connecting rod is positioned at this positioning recess place.Can conveniently drive valve rod like this when connecting rod swing slides up and down.
In above-mentioned float valve, described connecting rod is hinged on the valve body by bearing pin.Reduce the frictional force between connecting rod and the valve body like this, improved the efficient of transmission.
Compared with prior art, the advantage of this float valve is can regulate angle angle between connecting rod and the ball lever by the joint controlling mechanism of connecting rod and ball lever, make the moment size that acts on the spool obtain adjustment like this, can convenient and suitable the needs of different liquid levels.Connecting rod is hinged on the valve body by bearing pin in addition, has improved transmission efficiency.This floating ball valve structure is reasonable, water inlet and outlet is smooth and easy, installation and operation is convenient, the sealing reliability advantages of higher.
