Description

Discharge valve of floatage-type cistern with predefined drainages for toilet

The present invention relates to a kind of tank for excrement pan draining valve, especially the tank for excrement pan draining valve of forming by valve body, bleed off pipe, diaphragm seal, water shutoff turnover panel, switch hoist cable.

The market product tank for excrement pan draining valve of producing both at home and abroad mainly contains the three major types type at present, and promptly straight, hydrocone type, turnover plate type are now done one with regard to above three types of products and analyzed.1, straight: adopt hemi-spherical cavities rubber ball float as water sealing piece, when water level is low, it is in half floating state and causes and leak, the easily aging distortion of its structure shape of cavity ball float and not just not resetting, in use, the deviation that switch and connecting rod takes place easily causes and leaks, and straight is classified as obsolete product by country.2, hydrocone type: adopt bend pipe to exceed and use the water level water shutoff, its existing shortcoming is that volume is especially big, and general water tank can't generally be installed, and switch adopts carries that to carry the formula stroke long, will cause gas leakage after using a period of time, and it is inconvenient to use.3, turnover plate type: the modified of straight, shortcoming are big or small stepping draining to save water resource.

The purpose of this invention is to provide a kind of effective water-saving toilet bowl water tank drain valve, it is simple in structure, easy to use, stable performance, accomplish to preestablish the water saving fixtures that displacement size stepping discharges water at low cost.

In order to achieve the above object, solution of the present invention is: the stepping hairpin, groove, the adjustable bobber that adopt draining valve valve body that is installed in the tank for excrement pan of depth of water pressure buoyancy to be provided with protruding tooth, diaphragm seal, buoyancy water shutoff panel turnover device and flexible buoyancy are formed the big or small stepping water-drainage mechanism of being scheduled to the displacement device.Complete unit comprises draining valve valve body, bleed off pipe, diaphragm seal, the buoyancy water shutoff turnover panel by protruding tooth, stepping hairpin, groove, adjustable bobber, pivot pin, adjusting bolt, button spring, extension spring, switch hoist cable etc. and forms.It also has one group to adopt float buoyancy to preestablish the control turnover panel with the stepping hairpin to float and highly keep the water discharge time device, valve body is provided with protruding tooth, the turnover panel of diaphragm seal, stepping hairpin top is connected with valve body fulcrum pivot pin with float combination bottom, turnover panel, the stepping hairpin is provided with protruding tooth of pair of meshing tooth and groove, the stepping hairpin is connected with valve body fulcrum pivot pin makes the front and back shape of falling the pendular motion, the short float of turnover panel come-up stroke, the motion that slopes inwardly of stepping hairpin, groove combines with protruding tooth and shows little shelves drainage works state, and turnover panel come-up stroke long recess combines the back disengaging and shows big shelves drainage works state with protruding tooth.Stepping hairpin, groove bottom are equipped with and are regulated bolt and control the groove depth of going into that protruding tooth enters groove, coordinate the switch size shelves and start active force, with valve body fulcrum pivot pin junction the button spring is housed, quicken the separating rate of groove and protruding tooth, turnover panel top is equipped with extension spring and is connected balanced turnover panel come-up speed of service coordination switch sling length with the switch hoist cable.

Technical scheme of the present invention is as follows, a water shutoff turnover panel that protruding tooth is arranged is set on valve body, be embedded with diaphragm seal in the middle of the turnover panel, the top of turnover panel is equipped with extension spring and is connected the switch hoist cable, the stepping hairpin that is provided with bifurcated at the fulcrum pivot pin place of valve body is made the front and back shape of falling the pendular motion, the branch of stepping hairpin be provided with groove can with effective combination of protruding tooth on the turnover panel, the top of stepping hairpin connects adjustable bobber, by float at water middle water level height, low liter, the combination of falling the buoyancy that is produced and be active force control groove and protruding tooth with separate, the control turnover panel close port that resets that descends reaches the required displacement when preestablishing once flushing.The bottom of stepping hairpin is equipped with regulates bolt and button spring, and the effect of button spring is a separating rate of quickening groove and protruding tooth, and bolt can be regulated the degree of depth that protruding tooth enters groove, coordinates the startup active force of big or small gear switch.The extension spring on turnover panel top can be played the balanced turnover panel come-up of the buffering speed of service, is convenient to the length that the by-pass cock hoist cable is connected with switch lever.After in water tank, injecting water, utilize depth of water pressure VE buoyancy, cause stepping hairpin groove to tilt to draw close to be here and expect to combine shape with protruding tooth to turnover panel.After the water shutoff turnover panel is opened, turnover panel is under the inertia of rising buoyancy, being close to groove rises, after groove meets with protruding tooth, protruding tooth is gone into groove and is in conjunction with locking shape control turnover panel rise and fall and keeping the draining of the little shelves of opening, when drawdown in the water tank when required half chests water level is put, adjustable bobber on the stepping hairpin is exposed to the water surface, the float loss of buoyance is outwards toppled over, force groove to be thrown off with protruding tooth and separate, the water shutoff turnover panel loses descends reset the in advance half chests water that stops to discharge water of support force and discharges after being subjected to the current siphon active force.If earn releasing slots again after protruding tooth is gone into groove, turnover panel continues rising and reaches the draining of big shelves.Drawdown float loss of buoyance is outwards toppled over protruding tooth and groove is no longer met in water tank, and turnover panel descends with the water level discharging and reaches whole box water and discharge.So only need regulate the height of float on the stepping hairpin in advance, can determine displacement is how much, can accomplish that predetermined displacement size stepping discharges water.

Owing to adopted the vertical buoyancy of depth of water pressure in the above-mentioned solution, increase a simple stepping control assembly, can very reach the big or small stepping of predetermined displacement like a cork and discharge water, it is simple in structure, stable performance, how many costs that almost do not increase easy to use.Because opening and closing of water shutoff turnover panel is twin shaft heart location, diaphragm seal adopts dull and stereotyped sealing not yielding, so good seal performance can reach exhausted leakage purpose.The switch of various ways can be adopted in this programme, the interior supporting use of tank for excrement pan of different model, specification can be installed in.

The present invention is described further with embodiment below in conjunction with accompanying drawing one, accompanying drawing two.

Accompanying drawing one is that embodiment of the invention valve port is the closed condition schematic diagram.

Accompanying drawing two is that embodiment of the invention valve port is the little grade of view that discharges water.

Discharge valve of floatage-type cistern with predefined drainages for toilet of the present invention is provided with diaphragm seal (3), protruding tooth (4) is arranged, water shutoff turnover panel (5), extension spring (10), switch hoist cable (6), stepping hairpin (7), groove (8), float (9), pivot pin (13), regulates bolt (12), button spring compositions such as (11) shown in accompanying drawing one, accompanying drawing two on draining valve main body (1).Make description with regard to the duty of each parts behind the injection water in the water tank below.Inject in water tank before the water, turnover panel (5) descends and resets, and the last float (9) of stepping hairpin (7) lacks buoyant support power topples over to turnover panel (5) rightabout.After injecting water in the water tank, adjustable bobber (9) ascending motion after being subjected to depth of water pressure buoyancy function on the stepping hairpin (7), stepping hairpin (7) tilts to draw close to turnover panel (5) relative direction, groove (8) is expectation and the protruding tooth of turnover panel (5) (4) bonding state, groove (8) enters the orbit of turnover panel (5), depth of water pressure masterpiece is used in above the diaphragm seal (3), and each parts remains static, shown in accompanying drawing one.When pressing the flushing of little gear switch, power by Push switch is passed through push rod, lever affects switch hoist cable (6) pulling extension spring (10) to move upward by the fulcrum rotation, drive upwards come-up upset of water shutoff turnover panel (5), diaphragm seal (3) breaks away from valve port, because water shutoff turnover panel (5) to be cavity body promptly reliable self buoyancy and on-off action power rise, open fully until valve port, the protruding tooth of water shutoff turnover panel (5) (4) is in the orbital motion process of come-up, meet with the whippy groove (8) of injection in advance, protruding tooth (4) slips into the inclination buoyancy locking that is promptly produced by the float on the stepping hairpin (9) behind the groove (8), the rising buoyancy of protruding tooth this moment (4) goes up the VE buoyancy of float (9) as not overcoming stepping hairpin (7), (turnover panel this moment (5) is though still have rising buoyancy, but operation power is limited can't be broken away from protruding tooth (4) and go into the constraint that is subjected to float (9) buoyancy behind the groove (8)), turnover panel (5) promptly can not rise and can not descend, shown in accompanying drawing two, and keep the draining of the little shelves of opening.Water level in water tank is outwards discharging constantly, water level progressively drops to predefined required wash water amount, during general designation half chests water, adjustable bobber (10) is exposed to the water surface, loss of buoyance, rightabout to water shutoff turnover panel (5) is toppled over, and stepping hairpin (7) quickens under the effect of button spring (11), forces groove (8) to be thrown off fully with protruding tooth (4) and separates.Stepping hairpin (7) breaks away from the orbit of turnover panel (5), and turnover panel (5) loses support force, and turnover panel (5) does not but overcome the current siphon active force and is forced to that descending resets in advance and stops to discharge water half chests water and discharge though still have rising buoyancy.The process that discharges water of big gear switch once is described below, in water tank after the fills with water, after pressing big gear switch, the opening process of valve port discharges water the same with little gear switch unlatching, different is that big gear switch is more much longer than little gear switch opening travel by the switch open stroke of push rod, balance pivot rotary moveable, the protruding tooth (4) that makes turnover panel (5) surmounts the reset constraint of buoyancy of groove (8) and continues to rise meeting with can break through when groove (8) is captured locking, and the attitude that stops to remain stationary discharges water for big grade until being stopped to the come-up limit.When the drawdown in the water tank after half, float (9) is exposed to water surface loss of buoyance topples over to the rightabout of water shutoff turnover panel (5), stepping hairpin (7) groove (8) breaks away from the protruding tooth of orbit (4) of turnover panel (5) no longer joins with groove (8), for the smooth decline that turnover panel (5) is later is removed the obstacles.Water level continues to descend in water tank, and turnover panel this moment (5) also resets until giving out light with drawdown, reaches the discharging of whole box water.

Malfunctioning or the damage when water intaking valve, water level rises, and unnecessary water just flows into closet along the bleed off pipe outfall.
