Abstract

The utility model relates to a ball cock, comprising a valve body, a valve core, a swinging arm and a floater, wherein one end of the swinging arm is fixed on the floater, and the other end of the swinging arm is connected on the valve body through an opening pin; the valve core is connected on the swinging arm by a pin; the valve body is connected with a hexagonal nut and a fibre gasket; the valve core is composed of a piston end tightly embedded with a stopper plug; and the piston is a polyhedron and cooperated with a clearance of the round inner wall of the valve body. The ball cock has simple and compact structure, the valve core is a hexahedron and cooperated with the clearance of the round inner wall, the valve core moves up and down in the valve body, the resistance is small, the sensitivity is high, and the movement is rapid. Simultaneously, since the hexahedron is cooperated with the clearance of the round inner wall, the speed and the flow of the water entering into contain are larger than the cooperation between the round valve core and the round inner wall of the valve body. Because the speed of the water inlet is rapid and the flow is large, the valve can largely advance the work efficiency of the ice machine when used on the ice machine. The upper end of the valve body is provided with a nut which has a lining, and the nut can tightly fix the water inlet pipe which is unable to loose and ensure that the water inflow is consistent every time, thereby guaranteeing the quality of the produced ice cube.

Description

Float valve

Technical field

The utility model relates to a kind of float valve of controlling the water container water level.

Background technique

Existing float valve is many to be connected and composed by lever by float and valve core chamber, when water level arrives certain altitude, float drive lever moves spool and closes water intake, when water level falls after rise, float drives lever again and moves in the opposite direction, make spool leave water intake and open the valve water inlet, the valve impacting force is big in order to make, good airproof performance, water-tight, the length that generally can adopt the volume that strengthens float or add long lever realizes, but because of float, lever are subjected to the restriction of water container mounting point, so some float, lever can't adopt above-mentioned measure.

Patent No. CN200420081196.3 " piston type large flow ball float valve " is though provide also that a kind of water-outlet quantity is big, the float valve of good airproof performance, but be processed with main water outlet on his valve body and pay the mouth of a river, piston is provided with empennage, spring is installed, the middle aperture of intaking in addition of piston, its complex structure, difficult processing.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of float valve is provided, simple in structure, compactly cooperates, under the big or small constant situation of water intake, make that water intake velocity is fast, inflow is big with water container, and good airproof performance.

The technical scheme in the invention for solving the above technical problem is: float valve is made up of valve body, spool, rocking arm, float; an end of rocking arm is fixed on the float; the other end of rocking arm is connected on the valve body with cotter pin; spool is connected on the rocking arm with pin; be connected with hexagon nut, fiber pad on the valve body; described spool tightly is embedded with chock plug by piston end and constitutes, and described piston is polyhedron and valve body circular inner wall Spielpassung.

Compared with prior art, advantage of the present utility model is: the spool of this float valve is a hexahedron, cooperate with the valve body circular inner wall, spool in valve body on, following motion, resistance is little, highly sensitive, move quick, cooperate with circular gap because of hexahedron simultaneously, under situation with identical minimum clearance and identical water intake, water enters the speed of container and flow and all is greater than cooperation between circular spool and valve body circular inner wall, because of water intake velocity fast, flow is big, so this valve is used on the ice making machine, can improve the working efficiency of ice making machine greatly, the nut of belt material cover is equipped with in the valve body upper end simultaneously, can can not throw off intake pipe is fixed, guarantee each inflow unanimity, thereby guarantee to make the quality of ice cube, solved that the space of float valve is installed is limited because of ice making machine, can not improve the problem of ice making machine working efficiency with the volume that strengthens float valve.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

The outer surface of piston 5 upper ends is Hexagon or Octagon etc., and the centre is last big, following little stepped shaft through hole, and the lower end is two arc opening inserted sheets of band through hole, tightly is embedded with chock plug 4 and constitutes spools in the intermediate throughholes of upper end.

There is the taper water intake 12 of projection valve body 3 upper ends for externally threaded ladder pipe is arranged in the middle of the upper end, the lower end is lined with fiber pad 7 and is rotary with hexagon nut 6, and in the middle of the lower end opening 13, both sides being arranged is the plane that through hole is arranged.

Lining 1 is placed on valve body 3 upper end-hole, and presses solidly with nut 2 and valve body 3 and to be integral.

One end of rocking arm 10 is fixed on the end face of float 11, pass through hole on the piston 5 lower end inserted sheets and the through hole on another bending plate end of rocking arm with pin 9, piston 5 is fixed on the rocking arm 10, and the bending plate end that will have spool rocking arm 10 again inserts in the opening 13 of valve body 3 lower ends, as shown in Figure 2.

Pass through hole on 3 liang of planes of valve body with cotter pin 8, connecting into the rocking arm 10 and the valve body 3 of belt spool with cotter pin 8 is the rotating one of fulcrum, as shown in Figure 1.

This float valve can be installed on the ice making machine and use, during use, screw off nut 2 intake pipe (figure does not draw) is enclosed within outside the lining 1, screw nut 2 again and intake then, when water level arrives certain altitude, during design height, float 11 floats, and drives rocking arm 10 and rotates along cotter pin 8, driving the spool that is connected on the rocking arm by rocking arm 10 moves up, press closer water intake 12, promptly close the water source and stop into water, as shown in Figure 1 and Figure 2.When water has been made ice cube, water level reduces no buoyancy, float 11 and rocking arm 10 are under the effect of gravity, the drive spool moves down, make spool leave water intake 12, water intake 12 is opened, and water flows in the ice making machine for using so continuous periodic duty through the gap of 3 of water intake 12 and spool and valve bodies.
