Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
Reference picture 1-4, present embodiment proposes a kind of ball-cock assembly, including main valve 1, the drainpipe 2 that main valve 1 epicoele connects to
Draining in cistern 3, discharge outlet 4 side of drainpipe 2 is provided with sealing shroud 5, and sealing shroud 5 is connected with ball float control structure, floats
Ball control structure includes ball float 6, and when ball float 6 reaches the highest liquid level of cistern 3, ball float control structure controls sealing shroud 5 to close
Discharge outlet 4, main valve 1 is closed, and filling pipe stops to cistern 3 moisturizing, when ball float 6 reaches the minimum liquid level of cistern 3, ball float control
Structure control sealing shroud 5 processed leaves discharge outlet 4, and discharge outlet 4 is opened, and the water of main valve 1 epicoele is flowed out by drainpipe 2, so that main
Valve 1 is opened, from filling pipe to moisturizing in cistern 3.
This ball-cock assembly, controls the movement of sealing shroud 5 by ball float control structure, and only ball float 6 reaches during highest liquid level
Discharge outlet 4 can be closed by sealing shroud 5, it is to avoid continue to cistern 3 internal drainage, just meeting only when ball float 6 reaches minimum liquid level
Opened by sealing shroud 5, to cistern 3 internal drainage, therefore, the change of the open and-shut mode of discharge outlet 4 is only in highest liquid level and
Just can occur it is therefore prevented that the frequent unlatching of ball-cock assembly and the parts damages that cause during low liquid level.
Ball float control structure in present embodiment includes a rotatable pusher dog 7, the position of the pivot 8 of pusher dog 7
Fixing, pusher dog 7 one end connects sealing shroud 5, and the other end is rotatably connected to the ball float guide post 9 stretching into cistern 3, ball float guide post
It is arranged with ball float 6 on 9.Locating piece 10 and lower locating piece 11 are fixedly installed on ball float guide post 9, upper locating piece 10 is located at and stores
Near the highest liquid level in pond 3, lower locating piece 11 is located near the minimum liquid level of cistern 3, ball float 6 upper locating piece 10 and under
Move between locating piece 11.By ball float 6 to the active force of lower locating piece 11 and lower locating piece 11 so that ball float guide post 9 carries
Dynamic pusher dog 7 rotates, and controls the movement of sealing shroud 5 therewith by pusher dog 7.
Pusher dog 7 is also associated with position limiting structure, during the liquid level rising and liquid level decline of cistern 3, position limiting structure
Respectively active force in opposite direction is applied to pusher dog 7, make the state that sealing shroud 5 and discharge outlet 4 stay open respectively and close.Keep away
The change exempting from the state of generation discharge outlet 4 during the liquid level in cistern 3 raises or declines is it is ensured that structure ball float controls knot
The stability contorting of structure, it is to avoid destabilizing factor.
Preferably, position limiting structure is extension spring 12, and one end of extension spring 12 is fixed on pusher dog 7, and the other end is fixed on drainpipe 2
On, and the two ends of extension spring 12 are located at the both sides of the pivot 8 of pusher dog 7 respectively.
Just to discharge outlet 4, sealing shroud 5 is inlaid with seal gasket 13, seal gasket near the side of discharge outlet 4 to sealing shroud 5
13 are coordinated with discharge outlet 4.Hole 14 is offered on sealing shroud 5, one end of pusher dog 7 extend in hole 14.
When the water level decreasing of cistern 3, as illustrated in fig. 1 and 2, ball float 6 declines along ball float guide post 9, when ball float 6 declines
When contacting with lower locating piece 11, water level decreasing, the self gravitation of ball float 6 continues to decline, and lower locating piece 11 is applied accordingly simultaneously
Active force, ball float guide post 9 stress moves downward, thus driving pusher dog 7 to rotate, pusher dog 7 rotational band movable sealing sleeve 5 is away from row
The mouth of a river 4, discharge outlet 4 is opened, and in main valve 1 epicoele, medium is discharged, and ball-cock assembly is opened to cistern 3 moisturizing, now extension spring 12
Center line is located at pivot 8 lower section of pusher dog 7 so that pusher dog 7 is subject to the first moment, and the first moment makes pusher dog 7 have drive
Sealing shroud 5 remains on away from the trend of discharge outlet 4, therefore discharge outlet 4, constantly enters cistern 3, cistern with water
3 liquid level is gradually increased, and ball float 6 rises therewith, when ball float 6 is risen to and contacted with upper locating piece 10, as shown in Figures 3 and 4,
Because water level continues to rise, ball float 6 is subject to buoyancy, upper locating piece 10 is applied with active force upwards so that ball float guides
Bar 9 moves up, and pusher dog 7 rotates in the opposite direction, and discharge outlet 4 is sealed by band movable sealing sleeve 5, and the position of extension spring simultaneously 12 occurs
Change, the center line of extension spring 12 is located at the top of pusher dog 7 pivot 8, and pusher dog 7 is subject to the second moment, and the second moment makes to dial
Pawl 7 has the trend closing discharge outlet 4 with movable sealing sleeve 5, keeps the sealing to discharge outlet 4 for the sealing shroud 5, until next ball float 6 connects
Contact lower locating piece 11.
Sealing shroud 5 is arranged in positioning sleeve 15, and positioning sleeve 15 plays spacing and guide effect to sealing shroud 5, and sealing shroud 5 exists
Back and forth run in positioning sleeve 15 in the presence of the ball float guide post 9 of extension spring 12, positioning sleeve 15 is connected on drainpipe 2, draining
Mouth 4 is located in positioning sleeve 15, the side wall of positioning sleeve 15 has through hole 16, is flowed into by through hole 16 by the water that discharge outlet 4 flows out
In cistern 3.
In order to prevent arbitrarily rocking in cistern 3 of ball float guide post 9, the lower locating piece of ball float guide post 9 is below 11
Part be arranged with fixed cover 17, fixed cover 17 is fixed on the side wall of cistern 3, can limit ball float guide post 9 close
Run in suitable scope.
Specifically, the fixed form of the fixed cover 17 of present embodiment is：Ball float guide post 9 is near cistern 3 side wall
Side is provided with vertical fix bar 18, and fix bar 18 upper end is fixed on positioning sleeve 15, and lower end is passed through second connecting rod 20 and fixed
Set 17 is fixedly connected, and fix bar 18 lower end is fixedly connected with the side wall of cistern 3 also by first connecting rod 19.
Ball-cock assembly in present embodiment is to be applied in cistern 3, certainly can also apply the ball-cock assembly of the present invention
It is similarly used in environment to other.
Note, above are only preferred embodiment of the present utility model.It will be appreciated by those skilled in the art that the utility model is not
It is limited to specific embodiment described here, various obvious changes can be carried out for a person skilled in the art, readjust
With replacement without departing from protection domain of the present utility model.Therefore although being carried out to the utility model by above example
It is described in further detail, but the utility model is not limited only to above example, conceive without departing from the utility model
In the case of, other Equivalent embodiments more can also be included, and scope of the present utility model is determined by scope of the appended claims
