Description

Energy-saving flushing water tank and decompression draining valve are pressed in storage

Technical field

The present invention relates to wc flushing cistern and the flushing valve of various sanitaryware and current drainage valve, particularly various closets.

Background technology

In existing various fluids storage pressures stream device techniques, exist that pressure drop when its current drainage is large, the valve pressurized is large, difficulty in starting need to be by machine power, and need to consume the more energy, and the housing pressure-bearing is large, the high in cost of production problem.The problems referred to above comprise existing various sanitaryware particularly blowdown flushing elastic energy storing style wc flushing cistern and the straight flushing valve of water closet and pan and pit, all because of its draining valve outlet, flushing water water inlet in the closet body, or less than runner mouth cross-sectional area, cause water body in runner, to spread, and build-up of pressure reduces, and not reaching it can should have than non-elastic energy storing style wc flushing cistern and have that the flushing of making is cleaner, the problems such as developing result of water saving more.Such as the elastic energy storing style wc flushing cistern that one's early years, Guangdong east roc pottery Co., Ltd produced, not only there are the problems referred to above, also exist the structure of its water intaking valve assembly and draining valve assembly and reducing valve assembly extremely complicated, cause that cost of production is very high and fault rate high maintenance cost is high, also user's water supply pressure there is strict requirement, its applicability is reduced, and the pressure volitional check that will exceed the part of its pressure limiting, not only wasted the pressure energy resource but also reduced and rushed Xian Xiaoguo.Also comprise the patent No.: CN2719948Y, denomination of invention: " saving toilet " exists the problems referred to above and other problems equally.As by its signal accompanying drawing and as described in form of structure, no matter whether the form of structure of its draining valve can close the outfall that hydraulic pressure pressure is arranged in the case and (essence can't be closed), the turning that its current drainage road forms two an angle of 90 degrees makes the draining runner can not be vertically smooth and easy, cause the hydraulic flow dynamic pressure to lose in a large number by head, reduced its developing result, and spool large traversing stroke like this, make the very large pressure of decrement of back-moving spring large, when discharging water flushing, water in the water tank reduces and the hydraulic pressure pressure decreased, namely the pressure of the second half hydraulic pressure of flushing is less than the thrust of valve core reseting spring, spool is turned down even close the draining runner, add the loss of the pressure energy head that the upper runner bending causes, developing result is reduced widely, do not reach the goal of the invention that it rinses water saving well.It also exists simultaneously, even the form of structure of its draining valve can close the draining runner set up (according to its signal drawings and the embodiments explanation in fact can not), being subject to so large thrust and transferring on the control lever buckle head of its small size at spool end also is on its button 7, make need be very large firmly just can press, even child and old man are difficult to press the button draining, and do not have applicability, and water tank must bear the pressure that the air in the elasticity water pocket inflate compression water tank is produced because of water inlet, and this air takes up room etc. and to cause volume to reach greatly the problems such as cost increase.But study carefully the reason of the problems referred to above of its existing elastic energy storing style wc flushing cistern or device, the suffered fluid pressure of spool that mainly is outflow valve is that hydraulic pressure is too large, and do not have can be to spool decompression and/or with consuming excessive electric energy, opens due to the innovative technology of valve with just reaching available man power light.The compression area of spool is larger and hydraulic pressure is larger, and the gross pressure suffered with its end face vertical direction is just larger, when particularly using gag formula valve, opens more difficult with the manpower light finger.So, prior art is in order to start relatively easily draining valve under pressure, the stop valves such as the ball valve that the spool latus rectum is little mainly with the employing cost is high or butterfly valve, to alleviating the resistance of start, but not be to adopt the heavy caliber gag formula valve that cost is lower, more durable and the faster flow of flow velocity is larger, had influence on the elastic energy storing style wc flushing cistern with water-saving result, in the various sanitary equipment such as water closet, used and popularize.So Xian is rushed in the blowdown of present water closet, mostly be and adopt non-elastic energy storing style wc flushing cistern, therefore also greatly wasted water resource, and washed totally not.Because of each user's water system hydraulic pressure difference, and the larger required water of actual pressure is just fewer, and the less required water of pressure is just more, and prior art is not regulated inflow according to reality by the user according to above-mentioned situation, obtains better water saving and developing result.And existing pan and pit and urinating bucket mostly are the backwashing manner that adopts direct-through valve, but it exist as described above because of spool cross the little flushing water water flow of water latus rectum little in runner diffusion and pressure decreased, have influence on developing result.Generally only be that the O-ring seal wearing and tearing are leaked and all can not be keeped in repair and can only totally change even simultaneously complex structure, cost of production are high, use cost is very high, and start required firmly large, slow-closure device job insecurity or the inefficacy that can not rush rear benefit water or mend water, cause the not enough or problem such as too much waste water of water of mending.Comprise existing elastic energy storing style wc flushing cistern, exist equally after flushing, fail in pit, to mend deficiency and the problem of water etc.Also comprise the applicant at front patent application application number: energy-saving flushing water tank is pressed in 201010269487.5 storage, also existing used draining valve is non-decompression type draining valve, the same large needs of spool pressurized are indirectly with stream pressure valve starting drive or permanent-magnet valve starting drive, and energy consumption is also relatively large, the problem of the deficiencies such as and the structural concept of permanent-magnet valve starting drive is also perfect not to the utmost, and it is large that the power that can provide is less or title consumptive material multiple-effect rate is low, the startup commutation need be exerted oneself.Increasingly in short supply at existing valuable freshwater resources, and supply flushing water and a large amount of sewage of processing, the mass energy of required consumption, and directly and indirectly polluted environment, so need having, the social utmost point can make flushing health cleaner, that more save water and energy buy the tool douching technique.And various elastic energy storing style containers or the device of prior art, or the ducted pressure valve that is subjected to of pressure fluid, particularly do not have or do not possess to use electronic or allos hydraulic pressure or air pressure startup, and need by the manually actuated pressure valve that is subjected to, as particularly gag formula valve is very difficult to start the large and/or larger valve of pressurized of bore, or not can arrange or adopt bigbore valve, need to have equally being activated the valve decompression or manually gently opening new technology.

And lever force-saving mechanism is attached to be helped when starting decompression type draining valve type adopting, and starts more laborsaving and can change power thrusts; 2, the indirect actuated type of valve: this type is owing to wherein having adopted a kind of permanent-magnet valve starting drive, to utilize its fixed drive mechanism and the formed driving magnetic field of motion driving mechanism, and its field drives power is arranged to greater than the decompression relief pressure valve cartridge of draining valve or the suffered vertical gross pressure of spool of non-decompression type draining valve, driving the motion driving mechanism that is connected with above-mentioned spool moves, the drive core body opens and closes the outfall draining or closes, and indirectly starts; And adopt stream pressure valve starting drive type, and be the pressure fluid that utilizes water system, as its driving force power source, and its driving force is arranged to greater than the suffered vertical gross pressure of above-mentioned spool, indirectly open; A kind of powered version and adopt the electromechanical valve starting drive, because valve is through decompression, also seldom laborsaving light indirect startup of the very little and power consumption of the power of the motor drive mechanisms such as required motor or electromagnet.Adopt above-mentioned any mode, all can start with less less manpower the draining valve of very large above-mentioned spool area or gross pressure.The indirect actuated type of above-mentioned valve, have and the same significant beneficial effect of top direct actuated type, and have the more laborsaving and better compliance of startup and a wider scope of application, start energy consumption with seldom valve: solved existing air storing type pressure flushing cistern and be provided with the technology such as " saving toilets " of elastic force water pocket, because of the large startup of the required tripping force of their valve difficult, and the water outlet aperture of spool is arranged to much smaller than the cross-sectional area of the water inlet that is rinsed closet and delivery port, or draining valve is arranged on the sealing unreliability of the outer end of outfall, the water pressure energy head loss that causes, flow is little, reach water body and in the runner of closet, spread, cause flow velocity to reduce, the developing result that pressure drop etc. cause is poor, water consumption is many, advantage and the beneficial effect of the problems such as cost of production height; Two, the beneficial effect of affiliate program: the beneficial effect that 1, storage stream elastomeric bladder type is arranged: basic model can guarantee above-mentioned draining valve spool can the hermetically closing outfall and make runner vertically unimpeded with can start with man power light on the beneficial effect basis of heavy caliber draining valve, also can in water tank, be provided with storage stream elastomeric bladder, and can utilize fully the sealing function of elastomeric bladder, and the performance such as high resilient depression power.It can adapt to the hydraulic pressure of any water system, also have water inlet can be held, and the air in the water tank extruded or keep and the omnidistance pressure drop of draining little, developing result is better, and can make the volume requirement of water tank less, structural strength requires lower, both provided cost savings, more can adapt to again and be used in conjunction with various water closets and air can not followed draining yet and flowed away, obtain flushing better effect cleaner and that more economize on water.Also have double-deck sound insulation function, make into advantage and the beneficial effect such as water and draining be more quiet;

2, there are storage stream elastomeric bladder and water tank to be provided with the beneficial effect of intake and exhaust pass: because the port that need not to increase cost simple in structure that in water tank, arranges, storage stream elastomeric bladder expansion energy is discharged the air in the water tank swimmingly when making into water, can replenish more rapidly during draining, and it is more smooth to obtain the draining flushing, fault-free is more durable and obtain water tank and can arrange littlely, further saves the beneficial effects such as cost; The beneficial effect that 3, storage stream elastomeric bladder and air control valve type are arranged: also can be in water tank, air control valve simple in structure, that cost is low is set, it can be according to user's hydraulic pressure, and be rinsed the actual conditions such as flushing pollution discharge pattern of closet, regulate inflow, or increase and decrease air compressing amount and power, better utilized various favorable factors more scientificly, both escapable costs can economize on water more scientificly and improve again the advantage such as developing result and obtain the beneficial effect such as how better combination property; 4, have slow row to mend the beneficial effect of water storage chamber type: when in the outfall outer end of water tank, being provided with slow row and mending water storage chamber, can make each flushing after, internally do can be quantitatively for pit, more water saving, cleaner, more quiet benefit water etc.Solved prior art elastic energy storing style wc flushing cistern, can't mend water after the flushing, or adopted inaccurate the wasting water or malfunction of rate of water make-up of Slow Close technology, and during the benefit water of non-elastic energy storing style wc flushing cistern, had and leak and the effective effect such as a difficult problem that noise is large.Any form of structure and prior art form of structure above this arranges and is fit to reach quantitatively rear purpose of mending water.Energy-saving flushing water tank is pressed in this storage, also have can adapt to various such as hydrocone type, punching fall closet and the pit of the flushing pollution discharge patterns such as formula, direct-discharging, with use in any hydraulic pressure environment, more need not to water inlet step-down and hydraulic pressure is the bigger the better, can utilize cmpletely advantage and the beneficial effects such as its pressure energy.And the permanent-magnet valve starting drive of inventing and stream pressure valve starting drive, not only solved Xian's tripping force problem of rushing of closet, it can solve various containers and elastic energy storing style container or the device of prior art equally, or the ducted pressure valve that is subjected to of pressure fluid, particularly do not have or do not possess to use electronic or allos hydraulic pressure or air pressure startup, and need by the manually actuated many beneficial effects such as pressure valve that are subjected to, i.e. the present invention storage pressure energy-saving flushing water tank and valve starting device serve many purposes; Three, the beneficial effect of decompression draining valve: this decompression draining valve is a major part of the pressure of the storage among the application energy-saving flushing water tank still not, it can also be separately as a kind of Fluid valve, particularly as the valve used under pressure fluid such as the flush discharge valve of the existing direct-discharging closet that does not have a wc flushing cistern.Adopt storage fluid capacitance chamber type or straight tube circumscribed type or the built-in type of straight tube of being built in no matter be, all be to adopt extremely simple structure and cost seldom, with can keep in repair the reduction cost of use that increases the service life, particularly the sealing of the interface of relief pressure valve cartridge and decompression cover is easier, existing this relief pressure valve cartridge of means of press seals pattern of influent stream side that leans on of ratio is respectively to the pressurized stress equalization, more difficult leakage and seal are more durable, and it is more smooth and easy near isometrical heavy caliber, high throughput to have a draining latus rectum and water inlet pipe and drain aperture.The little pressure energy of spool latus rectum low discharge that has solved prior art lose large pressure drop large etc. affect its functioning efficiency effect, and the complex structure cost of production high, can not keep in repair application life short expense high, and easily leak and start the required problem such as large of exerting oneself.Has the large flow high throughput of large latus rectum, as as sanitaryware flush discharge valve, many beneficial effects such as the better cleaner more water saving of developing result, the more durable cost of use of low cost is low, startup is lighter, applied widely, the environment of and valve that bore larger higher especially for fluid pressure, the benefits such as its cost benefit and efficiency and action effect are just higher.Simultaneously can also be as the beneficial effect of the highly significant of the multiple uses such as living water use and other fluid course by-pass valve controls; But be provided with when delaying row's benefit water storage chamber type as the flush discharge valve of sanitary equipment and in the outfall outer end, have with top storage and press energy-saving flushing water tank to have slow row to mend the same beneficial effect of water storage chamber type, solved the problems such as the inaccurate or malfunction of the benefit water that can't mend water or slow-closure device of existing through-type flush discharge valve.It is associated that energy-saving flushing water tank and the beneficial effect of decompression draining valve are pressed in storage among the present invention, i.e. include two among the application the present invention and not only can cooperate but also can independently implement and the component invention of using and application.

The specific embodiment

The application is under a total inventive concept, has two associated but they can independently solve technical problem to be solved again, and has the multinomial invention of the beneficial effect of highly significant.Also be that independent entry decompression draining valve is that one of the primary structure feature of energy-saving flushing water tank and invention main points are pressed in the independent entry storage, it can independently use or do other purposes again simultaneously.And the water discharging valve in the energy-saving flushing water tank is pressed in this storage, be not only again with the decompression draining valve in the independent entry, also comprise all attainable form of structure that arranges of various non-decompression type draining valves, decompression type and conventional non-decompression type are namely arranged, and the various structures form that direct startup is arranged and indirectly start.And the indirect startup of valve has permanent-magnet valve starting drive type and stream pressure valve starting drive type and electromechanical valve starting drive type, and can increase function and put forward high performance additional aspects, they can both solve relevant and the technical problem that will solve correspondence proposed by the invention, with have significant beneficial effect, and be multiduty.Be that energy-saving flushing water tank and decompression draining valve are pressed in this storage, multiple flexibly embodiment is all arranged, the below selects representative embodiment and signal accompanying drawing, further specifies for example respectively.Also have, in the described various structure vocabularies of terms, because not having all accurate corresponding scientific term term to adopt with existing the art, make noun by oneself therefore part adopts.Reduce pressure as described draining valve, permanent-magnet valve starting drive, stream pressure valve starting drive etc., and purposes of the present invention not merely is applicable to the water environment for use, and namely described water has comprised other fluid.

1), the direct actuated type of valve one, the enforcement of energy-saving flushing water tank basic model is pressed in storage:: this example can be with reference to reference to signal accompanying drawing Fig. 1 and Fig. 2, if water tank 1 also is provided with water inlet 1A and outfall 1B in water tank, decompression draining valve 2 is installed on outfall the inner of water tank, and valve rod 2C is connected with relief pressure valve cartridge 2A.The draining valve of this routine type is decompression type, and described decompression draining valve can be with reference to the explanation of any of signal accompanying drawing Figure 10 and Figure 11 and Figure 12 and decompression draining valve independence embodiment, but illustrates that accompanying drawing comprises that following each example all only is to draw with the axle formula of moving.It is comprised of relief pressure valve cartridge 2A and decompression cover 2B and valve rod 2C.The poppet shaft formula of moving is: relief pressure valve cartridge 2A is comprised of core body and the sealing mat that is in the lower end, and be provided with one or multi-channel joint ring annular groove on core body top, and seal ring set is contained in the annular groove, certainly this sealing function structure also can be arranged in the decompression cover 2B through upper, do not affect their sealed nature, or adopt decompression cover and relief pressure valve cartridge direct contact seal form all can, but wear-resisting not being durable not.Described decompression cover 2B, it comprises the cover cylinder on top and the installation fixed cover pin of bottom, and to be provided with each cover body water inlet 2B1 and lower end to symmetry in cover pin section be that opening is cover body outfall 2B2.The internal diameter of upper lid cylinder equals or is slightly larger than the external diameter diameter of relief pressure valve cartridge, and be to be the periphery that decompression cover is sleeved on relief pressure valve cartridge, and be fixed on outside outfall the inner in the water tank by the cover pin and place, and the bottom end cover of relief pressure valve cartridge is on water tank outfall the inner.They are disjunctors for described cover cylinder and cover pin, its upper surface be semicircle be circular arc type or together with the upper end of relief pressure valve cartridge be arranged to approximate be dome-type all can, and more withstand voltage than material-saving, do not limit so it is various shape forms.Can contact sealing between decompression cover and the relief pressure valve cartridge, be more preferably seal ring seal.The keying that the so-called poppet shaft formula of moving is valve is axially movable about mobile relief pressure valve cartridge is done, so the space arranges highly in the decompression cover top, when moving the relief pressure valve cartridge draining, the up stroke space of being large enough to hold core body must be arranged, and can be arranged to vacuum type or gas storage type or atmosphere communicate-type.The atmosphere communicate-type can be by leaving the gap between the sealing navigation pipe that is made as hollow valve rod or valve rod and can be provided with, and they are connected with the water tank outside atmosphere.The gas storage type can utilize its compressed air as the reset function of relief pressure valve cartridge.Valve rod can pass water tank and pass decompression cover top and be connected with the relief pressure valve cartridge upper end, or pass decompression cover lower water inlet and relief pressure valve cartridge outside diameter to being connected, also can be that the lower end is connected with the relief pressure valve cartridge lower end from casing outfall outer end, it is also identical that such connection arranges below the form each example, but all illustrate accompanying drawing to be that type of attachment draws and be that poppet shaft is moved formula entirely, each example is also identical below this problem no longer repeats.And the relief pressure valve cartridge ring is rotating: the difference that it and reducing valve mandrel move formula is that mainly the structure of relief pressure valve cartridge is different, and the direction of motion of spool is different when making the keying of valve.Relief pressure valve cartridge 2A must be made as hollow type, and lower ending opening is as relief pressure valve cartridge outfall 2A2, it communicates with the water tank outfall, and the upper end can be opening or airtight, and it radially in offer the relief pressure valve cartridge water inlet 2A1 corresponding with the cover body water inlet 2B1 of decompression cover 2B.Described cover body water inlet 2B1 and relief pressure valve cartridge water inlet 2A1 can be single port or twoport or many mouthfuls of formulas, better is monosymmetric twoport or many mouthfuls of formulas, it can make spool radially each to pressurized balance more, be easier to seal anti-leak, their opening shape can be the circular shape such as oval or square water inlet all can and do not limit, certainly indulge the water inlet area of oval type and revolve the properties that moves distance and sealing better, sealing between them can be their directly contact sealings equally, or all can with the indirect sealing of seal.Described decompression cover and the relief pressure valve cartridge draining valve general structure shape that namely reduces pressure can be that cylindrical shape or approximate hemispherical type all can.And the lower end of decompression cover is connected with the inner periphery of water tank outfall and seals.This routine type decompression draining valve is when rotary spool, its water inlet communicates with the cover body water inlet and intakes, and whenever its outfall all keeps communicating with the water tank outfall, when rotation makes the relief pressure valve cartridge water inlet be threaded to the closed position of cover body again, it is the corresponding cover body water inlet in airtight place of relief pressure valve cartridge simultaneously, the decompression draining valve is in closed condition, and the flush discharge of water tank and hermetically closing function are adjourned to the water inlet of relief pressure valve cartridge.No matter being this axle, this decompression draining valve moves or encircles the startup form of revolving; because the protection pressure-bearing of decompression cover being arranged; relief pressure valve cartridge all is not subjected to vertical vertical water pressure pressure; and it be in the cover body water inlet hoop hydraulic pressure pressure each to stressed be balanced; and its keying direction be stressed perpendicular direction and not in the same way; its moving resistance essence only is frictional resistance, and this drag minimization is so be enough to the directly startup or more laborsaving by establishing lever force-saving mechanism of available hand.For the startup draining of valve, be directly with hand pull valve rod as shown in Figure 1, and can press down it and reset, or by its from gravity add back-moving spring or gas storage type decompression cover in the forms such as compressed air pressure all can realize resetting.And accompanying drawing 2 is to be provided with lever force-saving mechanism 5 in the outer end of described valve rod 2C on above-mentioned embodiment basis for the Labor saving machine configuration is arranged, and starts firmly and change power thrusts to reduce.This directly starts routine type, and they all have, and structure is extremely simple, dependable performance, can keep in repair the low usage charges land used of durable low cost and solved the problems such as the large startup difficulty of the existing spool pressurized of prior art.Implement this decompression draining valve, the axle formula of moving can also namely be in relief pressure valve cartridge core body hypomere the external diameter diameter of the corresponding position of decompression cover water inlet section, be arranged to have slightly from top to down dwindle, because the hydraulic pressure pressure of case inner storing water is respectively to identical, and core body is had the anti-holder power that makes progress, further reduce the resistance of start in the time of can aiding in the startup spool and when up, and more be conducive to keep sealing.But the taper design setting that this anti-holder power is the relief pressure valve cartridge hypomere should be less than or equal to the suffered vertical gross pressure of core body, as leaking greater than then covering incessantly outfall.In like manner, encircle rotating employing the outer of relief pressure valve cartridge is being set as non-circle through vertical, more be conducive to means of press seals, or valve rod 2C is connected with the relief pressure valve cartridge side direction and this connector has the structure of any favourable measure that limit function up and down etc. more optimizes, but this to be peripheral issue do not represent in the signal accompanying drawing; 2), the indirect actuated type of valve: can be with reference to reference signal accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, accompanying drawing 7.They are multiple different form of structure, permanent-magnet valve starting drive decompression draining valve type is described first: can be with reference to reference signal accompanying drawing 3, accompanying drawing 4, in water tank 1, to be provided with water inlet 1A and outfall 1B, decompression type draining valve 2 is installed on outfall the inner of water tank, permanent-magnet valve starting drive 6A, the disk vis-a-vis of its fixed drive mechanism 6A1 and motion driving mechanism 6A2 is answered, and motion driving mechanism is connected with relief pressure valve cartridge 2A through valve rod 2C.This type only is with the difference that top valve directly starts routine type, is to have adopted the permanent-magnet valve starting drive to replace directly starting with the hand pull or with lever force-saving mechanism, only is that other structure of difference of permanent-magnet valve starting drive is basic identical.Described permanent-magnet valve starting drive, can be built in the water tank or be built in the decompression cover 2B, again the operating handle connecting rod among the controlling organization 6A3 of its magnetic field is passed through water tank and be located at outside the water tank, or totally be located at water tank and be connected with relief pressure valve cartridge through valve rod more outward and all can.The structure of described permanent-magnet valve starting drive, the form that arranges that also has plurality of optional to select: it by fixed drive mechanism 6A1, and motion driving mechanism 6A2 form with the magnetic field controlling
