The lower end of described inlet opening is provided with push rod 6, the top of described push rod 6 contacts with the bottom of main-valve 3, the bottom outside of valve body 12 is stretched out in the bottom of described push rod 6, the bottom of described valve body 12 is provided with lever 7, one end of described lever 7 is hinged on the bottom of valve body 12, the other end of described lever 7 is provided with movable pulley 11, and the bottom of described push rod 6 contacts with lever 7, relies on lever 7 to support; The bottom of described valve body 12 is provided with fixed pulley, the bottom of described valve body 12 also arranges flexible body 8, the bottom of valve body 12 is fixed in one end of described flexible body 8, the other end of described flexible body 8 walks around successively movable pulley 11 and fixed pulley is connected on ball float 10, and described ball float 10 is positioned at the guide 9 for controlling cistern water level.
Described main-valve 3 is provided with damping hole being positioned at valve body 12 inlet segment one sides, and described damping hole can make core assembly in the time closing, and the water in valve body 12 inlet segments enters into core assembly inside from damping hole.
The gravity of described ball float 10 is greater than to the active force of push rod 6 pressure that sub-valve 5 upper surface pressure and little spring 13 form by movable pulley 11 and lever 7, makes ball float 10 in the time not being subject to buoyancy effect, and sub-valve 5 and main-valve 3 are all in opening.
Between described end cap 1 and valve body 12, be provided with sealing ring 14.
The course of work of the present invention: sub-valve 5 is coaxial with main-valve 3, packs in the hole of main-valve 3 with matched in clearance and the conical surface touches and coordinates mutually. The main-valve 3 that sub-valve 5 is housed is coaxial with valve body 12 respective aperture, packs in valve body 12 and with valve body 12 conical surfaces and touches and coordinate mutually with matched in clearance. Described little spring 13 is coaxial and pack in main-valve 3 holes on sub-valve 5 under spring abutment 4 with main-valve 3. Spring 2 lower end borehole jacks outside spring abutment 4 locating dowels and with spring abutment 4, pack in main-valve 3 holes with matched in clearance and spring 2 upper end holes outside end cap 1 locating dowel. Described end cap 1 studs with sealing ring 14 with the coaxial also and port joint fastening by thread connection of valve body 12 respective aperture. Described push rod 6 is loaded under sub-valve 5 and main-valve 3 with matched in clearance, on lever 7, among valve body 12 respective aperture. Described lever 7 is loaded under push rod 6, and one end is with matched in clearance and valve body 12 hinge-coupled, and the other end connects with movable pulley 11 with matched in clearance. Valve body 12 is fixed in described flexible body one end, and the other end is connected with ball float 10 with fixed pulley through movable pulley 11 respectively. Described ball float 10 is under flexible body 8 and be connected mutually, and among the guide 9 in communicating up and down, forms mechanical float ball water supply valve with large matched in clearance.
The gravity of ball float 10 is greater than to the active force of push rod 6 pressure that sub-valve 5 upper surface pressure and little spring 13 form by movable pulley 11 and lever 7, makes ball float 10 in the time not being subject to buoyancy effect, and sub-valve 5 and main-valve 3 are in opening.
When the gravity that ball float is 10 is less than its buoyancy, ball float 10 is subject to buoyancy effect along with water level rising relative gravity reduces gradually and trends towards zero. Push rod 6, sub-valve 5 and main-valve 3 lever 7 conduct oneself with dignity and the effect of little spring 13 and spring 2 under move down, and successively make sub-valve 5 and main-valve 3 in closed condition.
Guide 9 has dwindled horizontal drift and the liquid dynamic effects of ball float 10, and movable pulley 11 and lever 7 coordinate the relative gravity that has reduced ball float 10, and ball float 10 diameters are reduced.
Operation principle of the present invention is: in the time that high water level ball float 10 is subject to buoyancy effect, along with the gravity of the rising ball float 10 of water level reduces gradually the effect of movable pulley and trends towards zero. In the meantime, main-valve 3 and sub-valve 5 push rod 6 and lever 7 is conducted oneself with dignity and the effect of little spring 13 and spring 2 under move down, and priority contacts respectively valve body 12 and the main-valve 3 endoporus conical surfaces, a water under high pressure part for while right output port enters sub-valve 5 and main-valve 3 top by main-valve 3 damping holes compresses sub-valve 5 and main-valve 3, make right-hand member water under high pressure can not flow to left end, in closed condition.
In the time of low water level along with the decline of water level, ball float 10 is because flexible body 8 pins down, buoyancy reduces gradually, the gravity of ball float 10 increases gradually the active force of push rod 6 by movable pulley 11 and lever 7 and is greater than the pressure that sub-valve 5 upper surface pressure and little spring 13 form, sub-valve 5 is backed down, the water under high pressure on sub-valve 5 and main-valve 3 tops is because the flow of main-valve 3 damping holes is relaxed much smaller than the flow of sub-valve 5 dredging flow grooves, main-valve 3, by jack-up, makes right output port water under high pressure flow to left end by the main-valve 3 of opening. In opening.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.
