Abstract
The utility model discloses a floating valve. The end cover (2) of the valve is provided with an entrance channel (1), the inner of the valve body (3) is provided with a valve rod installing channel (14), and the valve body (3) is provided with an outlet channel (7). One end of a valve rod (9) in a valve core (13) is fixedly connected to a valve plate (10), a groove provided with the other end of the valve rod (9) is corresponding to the through hole of the valve body (3). Both sides of the through hole of the valve body (3) are provided with a fixed pivot supporter (8) for installing shifter lever (4), and the fixed pivot supporter (8) is fixed on the upper of the valve body (3). Because the utility model cuts off forwards, the float and the linkage only take the effect of closing by pulling valve plate, the lack of the original float valve is overcome completely.
Description
The utility model relates to a kind of valve, particularly float valve.
At present, the driving lever of commercially available float valve, decide the bottom of rotating shaft at valve body, working principle is a backward stop, and the major defect of backward stop valve is:
1, equipressure is ended, and reach isobaric purpose and depend primarily on the size of ball float and the length of connecting rod, with water example, in case the change of water supply pressure is big, and the size of ball float and length of connecting rod are definite, will cause the half cut-off state, cause out of control.
2, installing, requiring the mounting points of container that enough intensity is arranged, not so yielding, also can cause by out of control.
The purpose of this utility model is, provides a kind of size and length of connecting rod to mounting points, ball float less demanding, the float valve of better effects if.
The purpose of this utility model is by providing a kind of float valve with following structure to realize, this float valve comprises: valve body, end cap, valve rod, driving lever, decide rotating shaft, connecting rod, ball float, intake tunnel is arranged on the end cap, there is valve rod that passage is installed in the valve body, exhalant canal is arranged on valve body, an end and the valve block of valve rod in spool is fastenedly connected, the other end of valve rod has a groove, corresponding with the through hole of valve body, the through hole both sides of valve body have driving lever is installed decide rotary shaft rack, driving lever, connecting rod, ball float is fastenedly connected, and decides the top that rotary shaft rack is fastened on valve body, valve block is conical, at valve block and valve body contact position sealing gasket is arranged.
Forward end because this model utility adopts, thoroughly overcome the deficiency of original float valve, float and connecting rod only play the pulling valve block closes, and does not also have excessive bending strength on mounting points, therefore can play better control action.Valve block adopts conical, can reduce the resistance of water inlet.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model float valve schematic representation;
Fig. 2 is the utility model float valve valve body cut-away view.
On the end cap 2 intake tunnel 1 is arranged as can be known by Fig. 1,2, there is valve rod that passage 14 is installed in the valve body 3, end cap 2 and valve body 3 are for being threaded, exhalant canal 7 is arranged on valve body 3, an end and the valve block 10 of valve rod 9 in spool 13 is fastenedly connected, the other end of valve rod 9 has a groove 11, corresponding with the through hole 12 of valve body 3, the through hole both sides of valve body 3 have driving lever 4 is installed decide rotary shaft rack 8, driving lever 4, connecting rod 5, ball float 6 are fastenedly connected, decide rotary shaft rack 8 and be fastened on the top of valve body 3, valve block 10 is conical, at valve block and valve body contact position sealing gasket 15 is arranged.
During use, when liquid level has reached desired location, make driving lever 4 stir valve rod 9 by deciding rotating shaft, drive valve block 10 and forward close, cut off the source that liquid flows to, reach by purpose along liquid inlet by ball float 6 drivening rods 5.
Claims (3)
1, a kind of float valve, it comprises: valve body (3), end cap (2), valve rod (9), driving lever (4), decide rotary shaft rack (8), connecting rod (5), ball float (6), intake tunnel (1) is arranged on the end cap (2), there is valve rod that passage (14) is installed in the valve body (3), exhalant canal (7) is arranged on valve body (3), an end and the valve block (10) of valve rod (9) in spool (13) is fastenedly connected, the other end of valve rod (9) has a groove (11), corresponding with the through hole (12) of valve body (3), what there was an installation driving lever (4) the through hole both sides of valve body (3) decides rotary shaft rack (8), driving lever (4), connecting rod (5), ball float (6) is fastenedly connected, and it is characterized in that: decide the top that rotary shaft rack (8) is fastened on valve body (3).
