The utility model comprises a valve body, a valve body head, a piston, a piston cylinder, a pressure lever, a seal gasket, a stopper, a bottom cover, etc. The utility model is characterized in that a water input hole does not intersect the centre line of the piston cylinder, and an eccentric distance is between the water input hole and the centre line of the piston cylinder. When the water flows, the vortices generates thereby, and the capability of delaying automatically closing is formed. Simultaneously the utility model is provided with a pressure maintaining mechanism and a pressure relief mechanism for working in phase and overcomes a plurality of defects of existing flushing valves. Because the valve is novel in principle and simplest in structure, the cost is lower. The utility model has double functions of operating manually and automatically.
Description
The utility model is the automatic delay function flushing valve that a kind of principle design of utilizing the pressure difference that fluid whirl produces forms, and belongs to the valve type that uses on the sanitary fittings.
At present, the flushing valve of using in sanitary fittings mainly contains following a few class:
One class is common stop valve, and its shortcoming is that "on" and "off" all must be used handling, wastes time and energy and does not meet people's health psychology and use habit.Especially in public places, after often opening, nobody closes or fits badly reality conveniently, usually causes a large amount of losses of water; One class is to press the self-closing valve, and the shortcoming of this class valve is no delay function, and hand one leaves, and closes at once, uses inconvenient; Another kind of is that cistern float type is towards valve.The major defect of this class valve is that rate of fault is higher, the running water phenomenon often occurs, and especially in public places, the phenomenon of wasting water is more general.And when the hydraulic pressure of pipe-line system hanged down, the water outlet at the bottom of the case was difficult to close automatically, causes the long-time loss of water.Simultaneously, its cost height takes up room big and installation, keeps in repair more time-consuming.Last class is emerging so-called water saving flushing valve in recent years.The common drawback of this class valve is: the pressure of water system is not less than 1kg/cm
2The time, service behaviour is just more stable.When the pressure of water system during far below an atmospheric pressure, its service behaviour extreme difference: the one, water outlet does not have impulse force, is not enough to reach the requirement of flushing; The 2nd, almost become the running water state, can not normally close automatically, cause the waste of water.
The utility model be exactly at many deficiencys of above-mentioned valve class through improving, practice rises to installation a kind of simple in structure, durable, easy to manufacture, with low cost that the public designs, use, easy to maintenance and meet people's the health psychology and " the pressurize time-delay is from closing flushing valve " of operating habit.
Function of the present utility model is realized from closing mechanism and decompression mechanism by pressure-keeping mechanism, time-delay.Wherein, pressure-keeping mechanism is made up of valve body head (9), depression bar (12), depression bar lining (10), spring seat (6), sealing plug (16), big spring (5), locking ball (11), Regulation spring (14), adjusting screw (15) etc.; Time-delay is made up of valve body (4), piston cylinder (18), sealing gasket (2), bottom (1) and piston (3) from closing mechanism; Decompression mechanism is made up of the end spiral shell (19) on push rod (8) and the piston (3), cock body (20), spring (21), spring abutment (22), sealed steel ball (23) and end socket (24) etc.
Description of drawings is as follows:
Fig. 1 is the main sectional view of flushing valve.
Fig. 2 is the right side view of flushing valve.
Fig. 3 is the sectional view of piston.
Wherein: (1) bottom, (2) sealing gasket, (3) piston, (4) valve body, (5) big spring, (6) spring seat, (7) sealing gasket, (8) push rod, (9) valve body head, (10) depression bar lining, (11) locking ball, (12) depression bar, (13) button, (14) Regulation spring, (15) adjusting screw, (16) sealing plug, (17) large washer, (18) piston cylinder, (19) end spiral shell, (20) cock body, (21) spring, (22) spring abutment, (23) sealed steel ball, (24) end socket, (25) water inlet, (26) water outlet, (27) osculum.
Below in conjunction with drawings and Examples the utility model is illustrated in detail: precedingly address, this valve is promptly to be protected by three basic systems, and organic cooperation of pressure release and time-delay mechanism, co-ordination reach its pressurize time-delay from closing purpose.The working principle of pressure-keeping mechanism is: after putting in place with hand push moulded rod (12), locking ball (11) snaps under the effect of Regulation spring (15) in the location circular groove of depression bar (12), simultaneously, sealing plug (16) has entered the cylindrical hole part of the water outlet (26) of piston cylinder (18).And with this mouthful shutoff.When the water yield of water system can not reach developing result very little, then since the water pressure of system less than the clamping force of the locking ball of setting, can not back down sealing plug (16), thereby this valve still is in closed condition, avoided the wasting phenomena of the long stream of little water, but after the hydraulic pressure of system increased to the clamping force of the locking ball that has overcome setting gradually, sealing plug (16) will be automatically, backed down suddenly, valve will be emitted the bigger current of one impulse force, reach the effect of flushing.Sealing plug (16) automatically resets under the momentum effect of big spring (5) and water simultaneously.After flushing process had arrived the time of setting, the following a bit of inner conical surface of the sphere end socket (24) that piston (3) relies on its top and piston cylinder (18) water outlet (26) matched and seals, thereby the current automatic time delay turn-offed.
Time-delay from the working principle of closing mechanism is: the center line of the center line of water inlet (25) and piston cylinder (18) is non-intersect, interlace one between the two apart from e, under the effect of this eccentric distance e, when current when flow out through piston cylinders (18) (25) from the water inlet, on the centerline direction of piston cylinder (18), will form a vortex, owing to have the gap between piston (3) and the piston cylinder, on the effect lower piston (3) of this vortex, pressure difference has just appearred in lower surface, learns the liquid force of the liquid force of piston upper surface less than its lower surface by the theoretical proof and the experiment of strictness.Under action of pressure, piston (3) is located to move to piston cylinder water outlet (26) during flowing water lentamente, till closing water outlet automatically.Piston from begin to move to close water outlet (26) fully be delay time during this period of time, this time can be set by actual demand.
For people laborsaving when opening valve, the utility model has designed decompression mechanism, its working principle is: when people push depression bar (12), the lower end of push rod (8) at first contacts with ball sealer (23) in the piston, and it is pushed away the sealing inner conical surface of end socket (24), make the original static pressure water that is sealing the piston base of piston cylinder (18) water outlet (26), release from the inner conical surface of end socket (24) and the gap between the sealed steel ball, thereby the bulldozing operation power of opening valve is greatly reduced, after hand is left away, push rod (8) is under the effect of big spring (5), its lower end makes it recover seal action away from sealed steel ball (23), has guaranteed that time-delay under the vortex differential pressure action of piston is from the pass ability.
Do an explanation with regard to the molar behavior and the function of the utility model " pressurize is delayed time from the joint backwash water valve " below:
When water supply pipline system had water, this valve was in automatic closed condition, and promptly to rely on a bit of inner conical surface below its sphere end socket (24) and piston cylinder (18) water outlet (26) to close envelope close for piston (3).When needing bath, press button (13) that depression bar (12) is put in place with hand push, locking ball this moment (11) snaps in the annular positioning groove of depression bar (12), and sealing plug (16) is again with piston cylinder water outlet (26) shutoff simultaneously; Piston (3) is in the bottom of piston cylinder (18).In the pushing process, pressure release is carried out with the sealing inner conical surface that the sealed steel ball (23) in the piston (3) pushes up from end socket (24) always in the lower end of push rod (18), thereby has reduced steering force.
After hand leaves button (13), when pressure of supply water during greater than the dwell pressure set, sealing plug (16) is backed down by water pressure at once, and under the effect of big spring and waterpower, be returned to the position of operation at once, water route circulation this moment, piston (3) then carries out the process of automatic delay function under current vortex action of pressure, after reaching the delay time of setting, the end socket (24) of piston (3) matches with the inner conical surface of piston cylinder (18) water outlet (26) bottom and seals, and has automatically shut down current.But when pressure of supply water during less than the dwell pressure set, sealing plug (16) can not be backed down at once, and valve still is in off state, has avoided the wasting phenomena of the long stream of little water.After hydraulic pressure raises, this valve will be opened automatically and wash, and delay time simultaneously to be in closed condition from the process of closing up to valve.
The index of delay time length is set by actual demand.This index can be realized by the reasonable combination of all structural parameter of weight, stroke and the time-delay mechanism of the gap between throw of eccentric, the piston cylinder, piston.
The restriction pressure of pressure-keeping mechanism by the needs of actual use occasion, is realized by the difference of adjusting screw (15) to the decrement of Regulation spring (14).
Angle a between the center line of the center line of water inlet (25) and piston cylinder (18) can get different values by actual demand, generally gets a=90 °.
The utility model is compared with existing similar thrift lock, have simple in structure, durable, processing performance is good, the equal advantage such as convenient of installation, maintenance, operation, and have, automatically and the dual-use function of manual-lock, wherein, the manual-lock function is to reach after entering the delivery port (26) of piston cylinder (18) by bowl-type rubber seal plug (16). Smooth for making sealing-plug (16) enter delivery port (26), inner conical surface is made on top at the delivery port (26) of piston cylinder (18), and moving closing function is guaranteed by " vortex time-delay mechanism ", be that piston cylinder (18) is between the inlet opening (25) and its apopore (27) of valve body (4), and the center line of the center line of inlet opening (25) and piston cylinder (18) is non-intersect, an eccentric distance e is staggered between the two, during current, produce thus a vortex, under this swirling action, piston upper, lower surface has produced pressure differential, thereby make piston slowly mobile, cut off the water supply until the end socket (24) of piston (3) contacts rear sealing with the inner conical surface of piston cylinder (18) delivery port (26) bottom. Simultaneously, for laborsaving when opening, be provided with the pressure release check valve in piston (3), it is made up of inner conical surface, spring (21) and the end spiral shell (19) etc. of sealed steel ball (23), end socket (24). This valve is very wide to the accommodation of hydraulic pressure. Can be at 0.2kgf/cm2About to 6kg/cm2Pressure under the normal operation reference time delay also very wide, can be between 1 second to 1 hour Set arbitrarily, to adapt to the use of different occasions, its manufacturing cost only is 1/2～3/4 of existing water-saving flushing valve. Washing no more than 6 liters of water consumption, is reliable and water tank type is about the serviceability of 16 liters of these valves by facts have proved. This valve is also very general to the requirement of manufactured materials, and all antirust, as: piston, piston cylinder, depression bar etc. can also be used the plastics manufacturing, and other materials is identical in general valve.
