Description
The present invention relates to the closet flushing control valve that a kind of lavatory flushing water closet pan is used.Be assemblied in the traditional water-closet tank.
Present closet flushing control valve is a bath class mostly.The discharging quantity of water size, the user can't regulate control, and the flushing of excrements is all with same discharging quantity of water flushing water closet pan.And the Seal Design of flush valve rationally causes the serious consequence of leaking inadequately.
For example: a kind of old-fashioned closet flushing control valve.Water-closet tank is provided with a bath control knob, and knob axle one end is fastened with lever, and the lever other end is pulled strings and connected the flushing valve valve block.The knob axle is matched in clearance with cover, and axle can rotate in predetermined angular.After turning knob, knob can reset because of the deadweight of lever.Valve block is that hollow can be floated rubber parts, and valve block hangs on the overflow gas tube with the valve seat disjunctor, makes it and valve seat annular wire sealing surface is fitted, and makes seal and uses.Valve seat is a hollow tube, is anchored on the water outlet of water tank.During work, turn knob to predetermined angular, lever makes valve block and valve seat leave, open and float by pulling strings, and flush valve is opened and flushed the toilet.Along with drawdown during to setting, the flush valve valve block is closed flushing valve owing to current gravitation and deadweight effect.The automatic water inlet valve that is provided with in the water tank is then opened water inlet during to setting automatically because of drawdown, when the water in the water tank during to set amount, automatic water inlet valve is closed because of the effect of float.At this moment, flush valve mechanism all resets, and finishes the process of flushing the toilet.The flush valve of this kind of pattern, it is very serious to leak.Key issue is on Seal Design, and seal becomes plane parallel to contact with valve seat annular wire sealing contact surface, and due to limited conditions, the sealing contact surface machining accuracy can not reach seal request.So sealing is to rely on the natural pressure of water to be pressed on the valve block, makes seal make elastic deformation to remedy the deficiency of precision.Hydraulic pressure in the water tank generally has only 10-15 centimetre.Do not have enough pressure to make seal produce enough elastic deformations at all, offset this error, make it to form good and stable sealing state.Therefore, drainage is inevitable thing.
At present a kind of more new-type seat lavatory hermetically-sealed construction has been done some improvement.Seal form is still plane parallel contact seal.Valve block and valve block are led becoming hollow tubular, also can make the overflow gas tube and use.Lead being provided with locking tooth.Set up float lever mechanism, float lever mechanism fulcrum is located on the valve seat, and valve seat is provided with the planer-type valve block steady of disjunctor, and the steady middle part is porose, and valve block is led inserting wherein, and valve block can move up and down betwixt.The float buoyancy of lever float mechanism was pressed on the valve block by the lever other end when flushing valve cut out, and made seal produce elastic deformation and sealed.Button is fastened on the tank lid.Button is established up and down movably push rod, utilizes spring to make it to reset.Push rod lower end ejection lever, lever other end bolt is pulled strings and is connected with valve block.It is right to press button, and lever is outwards upwards made the garden arc and moved through to pull strings and provoke valve block, and flushing valve is opened.Valve block is shored on locking tooth and can not be descended because of the float lever end.During to definite value, float lever is sagging along with drawdown, and locking tooth is left in the float lever end, and valve block falls, and flushing valve cuts out.Automatic water inlet valve is intake automatically.Along with water level rises, the buoyancy of float lever is pressed on the valve block by lever end, thoroughly closes flushing valve.This kind of also is a bath retaining towards control valve.Leak resistance has improvement greatly, but antidrip still fails to solve at all.Its reason is that the float of lever float mechanism can not be excessive, and excessive then button can not be pressed like a cork, too small deficiency again so that seal enough elastic deformations are arranged and seal.In addition before water level did not rise to the float lever compacting and works, it was still quite serious to leak.And seal and the long-term folding friction of valve seat annular wire sealing surface form corresponding groove inevitably and destroy air-proof condition, and sealing performance is worsened.The anti-drip performance of this kind of design still fails to solve at all.
Another money is at the drip-proof draining valve of flushing valve.Be that Cao Jifu applies for that on July 24th, 1 utility model patent, the patent No. are " the flexible valve seat draining valve of flush toilet " of ZL97240406.6.This design advantage has been to make full use of the existing air-proof condition that provides of toilet, sets about from changing Seal Design, and sealing contact surface is changed into sphere radial wedge extruding contact from plane parallel compacting contact.Thereby solved plane parallel contacting pattern seal and do not produced the seepy question that enough elastic deformations cause because of there being enough pressure.Specific practice is: seal is the O-ring seal that a section becomes wedge-like, is embedded on the valve seat mouth of pipe.The valve block contact surface is designed to spherical.Valve block was with the O-ring seal lip of spherical wedge-like extruding section wedge-like when flushing valve cut out, form the contact of sphere annular wire, the embedding of the sealed circle bag of the spherical contact surface of valve block is because contact condition has certain friction, the sealing contact condition that sealing contact surface all is in well from start to finish.Because section wedge-like O-ring seal lip is thinner, is easy to produce excessive elastic deformation according to test.The bad again grasp of the soft degree of sealing ring.Seal can easily generation is tired under the excessive squeezed state follows the string gradually because of being in for a long time, destroys desirable annular wire sealing contact condition.Service time, length will produce weeping slightly.This kind of design, because of seal can not be durable in use, the practicality that seems deficiency.
According to another report, Beijing has developed two very strong inferior closet flushing control valves of bath retaining of a cover matching recently.Because of I do not have interrelated data and material object, so have no way of stating.
The present invention be directed to above-mentioned deficiency and establish a kind ofly have a no water clock, only need an operational motion, then can obtain a big young waiter in a wineshop or an inn different quantities of flush water flush valve.And two bath retainings time all can be with the required size of regulating discharging quantity of water voluntarily of user.If combined type button, knob switch cooperate to improve matching performance with the storage tank of an existing switch installing hole in the use.The closet flushing control valve that make production, the traditional toilet in using all can successfully adopt the present invention.
Design concept
