Description
Technical field
The present invention relates to the float valve that a kind of filling flush tank is used, it has a float that is connected with the valve body that can move vertically, valve body and the valve seat cooperating that is connected the entry nozzle of the spray pipe on the supply pipe.
Background technique
The known such float valve of DE 3153688C2 by the applicant.This float valve is used to control water and enters the lavatory flushing water tank and a valve body is arranged, and valve body connects the driving mechanism motion and remains in closed position by one.The velocity ratio of this connection driving mechanism is little and much bigger at the end of closing movement in the beginning of closing movement.This variation of velocity ratio in the closing movement process provides higher reliability for preventing to raise or undesirably open valve during pressure change in the supply pipe internal pressure.
The crucial buoyancy that is to determine like this float promptly, makes valve also can be connected hydraulic pressure and is higher than on the supply pipe of mean value in this float valve.Therefore, the buoyancy of float must be best buoyancy when having average or less hydraulic pressure when supply pipe.By in the float valve of above-mentioned file or in similar valve, the buoyancy of float is usually in about scope of 1.6 to 2.0N.The buoyancy of float depends on its volume basically.Big buoyancy can only reach by the volume that correspondingly increases float basically.
Usually draw from for example being contained in the country of the raintank on the roof at those sparge waters, the altering a great deal of hydraulic pressure, and also lower usually.Inlet pressure may for example have only 1bar in this case.Therefore, the float that is adopted so far for this lower pressure has unnecessary big buoyancy and unnecessary big volume is correspondingly arranged.Especially for concealed flush box, for the consideration of saving the spatial position certainly, as far as possible little float is to be worth pursuing.This in principle float can be changed.But compare complexity like this and must in the warehouse, correspondingly have different floats or float valve.
Summary of the invention
The objective of the invention is to create the float valve of the described type of a kind of preface, its compact structure and volume are little, and reliable operation however.
For achieving the above object, by the invention provides the float valve that a kind of like this filling flush tank uses one float is arranged, it is connected with a valve body that can move vertically, valve body and the valve seat cooperating that is connected the spray pipe entry nozzle on the supply pipe is characterized in that: be provided with the device that is used for changing the nozzle throat area that will seal.
Because the nozzle throat area that will seal in by float valve of the present invention can change, so just can mate with the inlet pressure of water the nozzle throat area.Under the situation of high unusually water inlet pressure, reduce this nozzle throat area, when import hydraulic pressure is very low, then correspondingly increase.Therefore, the power that acts on when valve cuts out on the valve body is complementary with the power of closing of valve best.Meanwhile, charging quantity also mates with it best.When hanging down, the inlet pressure of water correspondingly increases the also suitably increase of nozzle throat area and charging quantity.So float needn't design excessive size from the beginning, because can avoid certainly that by adjusting the nozzle throat area thundering big power is arranged when valve cuts out on valve body.
Evidence, buoyancy is best in 1.2 to 1.5N scopes in by float valve of the present invention.Corresponding to this less buoyancy, it is little that the volume ratio of float is used always.This just is more convenient for inserting the inside of flush box, and especially this point is particularly conducive to assembling and inspection work for concealed flush box.Accessible in addition best charging quantity is about 200cm
3/ sek.Therefore six liters of sparge waters are filled it up with in 30 seconds again.
If the nozzle throat area can infinitely change, then can accomplish the special best nozzle throat area of adjusting exactly.By a kind of further development, this can the very economical and realization reliably by means of a kind of object of elastically deformable.By of the present invention further develop this object be hose-like and can be by the regulating mechanism distortion of radially extending.
By a further development of the present invention, be used to change the device of the nozzle throat area that will seal by the rotatable dish realization that has a plurality of through holes that maybe can swing.Select through hole corresponding to the optimum nozzle cross section as valve seat by rotating this dish.Therefore can be very simply and promptly be adjusted into appropriate nozzle throat area.
Description of drawings
Further specify two embodiments of the present invention by means of accompanying drawing below.In the accompanying drawing:

Fig. 2 a is by the section by a float valve part shown in Figure 1, and wherein valve is being opened;
Fig. 2 b is along the part sectioned view of arrow IIb-IIb direction among Fig. 2 a;
Fig. 3 a passes through the part section by a kind of float valve of modification, and wherein valve is also being opened; And
Fig. 3 b is along the view of arrow IIIb-IIIb direction among Fig. 3 a.
Embodiment
The float valve of representing among Fig. 11 has a valve casing 22, by means of locking nut 3 fixed tube joint 2 detachably on valve casing.The spray pipe 7 that is shaped on through hole 4 is clamped between pipe joint 2 and the valve casing 22 with clamping ring 6.Spray pipe 7 seals with respect to pipe joint 2 by means of Sealing 5.
Spray pipe 7 has a valve seat 9, and it is located at the central authorities of flow guiding screen 7b substantially.Valve seat 9 and valve body 16 cooperatings, valve body 16 has a rubber seal 16a.Valve body 16 is pressed on the valve seat 9 by rubber seal 16a in Fig. 1.Thus valve cuts out, do not have sparge water to enter in the annular chamber 10 of valve casing 22 through the hole 4 of spray pipe 7.
The pressure of valve body 16 applies by float 19, float on outer pipe 21, be guided for vertical movement and by figure in the push and pull system 20 that preferably is designed to connect driving mechanism that only schematically illustrates be connected with lever 11.Push and pull system 20 and float 19 can be by above-mentioned DE 3153688C2 designs.Float 19 is in the flush box and correspondingly is subjected to a buoyancy.Buoyancy is passed to valve body 16 through push and pull system 20 and lever 11.
Shown in Fig. 2 a and 2b, the diaphragm 8 of in the hole 4 of spray pipe 7, pack into a hose-like and rubber elasticity, its end face 8c flushes substantially with valve seat 9.Diaphragm 8 has a radial flange 8d to be used for it is fixed in the spray pipe 7 in its end.Regional endoporus 4 at diaphragm 8 is expanded by a bigger hole 13.Another tapped hole that radially extends 14 stretches in this hole 13, and headless screw 15 is packed in the tapped hole 14.The end face of headless screw 15 abuts on the outside of diaphragm 8.By represented position in these figure that mention, diaphragm 8 is by headless screw 15 resiliently deformable slightly, makes nozzle throat area A by Fig. 2 b become nozzle throat area non-circular and when not deforming less than diaphragm 8.If the distortion of diaphragm is then infinitely cancelled in headless screw 15 upwards motion tapped hole 14 in Fig. 2 a, whole circumference abut in and nozzle throat area A becomes circle also thereby greater than shown in Fig. 2 b in the hole 13 in along it until diaphragm 8.If headless screw 15 is further radially inwardly motion in Fig. 2 a and 2b, then correspondingly further reduce nozzle throat area A.Therefore, correspondingly be out of shape, can infinitely in certain lit range, change nozzle throat area A by diaphragm 8.This has correspondingly changed when valve cuts out because the power of hydraulic action on valve body 16 in the spray pipe 7.Under the high unusually situation of hydraulic pressure, can by suitably screw in headless screw 15 and thereby reduce nozzle throat area A, infinitely reduce the active force on spray pipe 16.Under opposite situation, outwards screw out headless screw 15 and correspondingly increase nozzle throat area A.
In the form of implementation of pressing Fig. 3 a and 3b, spray nozzle plate 17 be contained in spray pipe 7 ' radial groove 18 in, by Fig. 3 b spray nozzle plate 17 a plurality of for example four nozzle bore 17a to 17d are arranged, these nozzle bores have different nozzle throat area A or A ' etc.Spray nozzle plate 17 be rotatably mounted and can be for example by means of among the figure not the lockable mechanism of expression be fixed in four positions any one.The through nozzle hole 17a that has maximum nozzle cross section A under the position of the spray nozzle plate 17 that Fig. 3 b represents is effective.Therefore, in this form of implementation, also can change the nozzle throat area.But this change is not stepless, but is step-like according to the classification of through nozzle hole 17a.
Being adjusted at when assembling of nozzle throat area A carried out.Usually this nozzle throat area A has fixed and has had only just change once more under special circumstances after assembling, but can adjust at any time in principle again.The nozzle throat area A that adjusts can check after assembling, washes for this reason and correspondingly fill it up with again flush box.Available here simple method checks best charging quantity for example to be 200cm
3/ sek.The advantage outstanding by float valve of the present invention is that this change can reach by the part of fairly simple cheapness.Compare with known float valve and need not to change working method.Yet, because the nozzle throat area can be complementary with inlet pressure best, so the float 19 that is adopted has smaller volume and less buoyancy is correspondingly arranged.
