Summary of the invention
It is a kind of simple in structure that the object of the invention is to provide, and the bidirectional flexible sealing is reliable, and the flexible spool of maincenter diaphragm time-delay with low cost replaces traditional piston time-delay mechanism.
Another object of the present invention is to adopt novel sealing pushbutton unit and stealthy whole button, solves traditional long draw push button starting handle operation effort and friction sealed wearing and tearing water clock problem.
Above-mentioned purpose of the present invention be by, maincenter diaphragm spool strain hydroecium volume, change and establish traditional time-delay valve cylinder sleeve stroke, float by maincenter diaphragm spool is concavo-convex, replace conventional piston, joint ring, cylinder sleeve, the flap rubber cushion, and utilize the stealthy whole button pressure relief mechanism that can the concavo-convex plane composite material of little change constitutes, finish normally closed, open bath, the technical scheme of delay-self-closing realizes, its formation comprises: the water-inflow and drain valve seat, maincenter diaphragm spool, the abnormity inner cap, stealthy whole button cover, the protruding in the form of a ring circle of water inlet valve port that it is characterized in that described water-inflow and drain valve seat, sealing ring in the ring end face build-in flexibility of described water inlet valve port, the draining inner chamber is oblique recessed wide groove and around the water inlet valve port in the form of a ring, the bead place fixes a similar smooth disc shape and opens a circular hole and the spacing ring washer of porous of many apertures on every side in central authorities between groove, then lay maincenter diaphragm spool above, described maincenter diaphragm spool, reinforcement epithelium for a similar disk, diameter equals water-inflow and drain valve seat inner chamber aperture and at maincenter diaphragm center rivet clasp one damping hole mouth, described special-shaped inner cap, it is a concavity hydroecium chamber, its rear end is provided with pressure release passage, the corresponding water-inflow and drain valve seat of bezel ring, end face and compress the sealing of maincenter diaphragm spool ring limit and be solidified as a whole in the described abnormity.
Adopt maincenter diaphragm spool operating principle of the present invention as follows:
When maincenter diaphragm valve core A face smooth in the water inlet valve port, it is normally closed shape, the spool B of maincenter film place face hydroecium is full of its pressure of water and equates to hydraulic pressure in the chamber, because of its A face, B face, the effective function area does not wait, and maincenter diaphragm A face middle part is tight against on the water inlet valve port, hydraulic pressure high sealability more is tight more, and when low pressure supplied water, the then effect of the compensation sealing valve port of the low hydraulic pressure spring of performance be what deserves to be mentioned is; Maincenter diaphragm spool has certain flexibility, and the sealing ring of the ring end face build-in of water inlet valve port also has certain flexibility, forms with gentle sealing anchor ring to softening, even if the water inlet valve port is somewhat crooked, also can cooperate its sealing surface voluntarily, guarantees the reliability of sealing.During bath, as long as destroy the pressure in hydroecium chamber artificially, as adopting electromagnetic relief valve or starting stealthy whole button, the interlock relief valve, at this moment, the pressure that maincenter diaphragm spool A face is fed water, and to float protruding in B face hydroecium chamber one side comprehensively, is equivalent to maincenter diaphragm flap and opens draining.Damping hole mouth through maincenter diaphragm central authorities feed water simultaneously slowly to the water filling of hydroecium chamber, make the stressed and slow deflection water inlet valve port of maincenter diaphragm spool B face, it may be noted that, maincenter diaphragm spool, with conventional piston swept volume total amount, disperse, extend to and have on the larger area maincenter diaphragm, thereby make its limited concavo-convex unsteady stroke, just can satisfy the condition of hydroecium chamber time-delay cubical content, when damping hole continues water filling, because maincenter diaphragm A face middle part is subjected to the pressure from water inlet, maincenter diaphragm spool B face hydroecium chamber one side can not be parallel protruding in opposite side, but at first act on the low hydraulic pressure zone of maincenter diaphragm B face circumferential edge along the position, is pushed into the spacing ring washer of porous, maincenter diaphragm spool A face central part and water inlet valve port spacing have been guaranteed therebetween, to satisfy the requirement of flushing the toilet of big flow, then, maincenter diaphragm spool continues to be subjected to the hydraulic pressure strain protruding in the centre, utilize hydraulic pressure to force maincenter diaphragm spool, close and be close to into water valve port, finish once bath, the delay-self-closing operating mode.Time-delay length depends on the ratio in hydroecium volume and damping aperture.Consider the flexibility and the intensity of maincenter diaphragm spool, also can embed the braid of nylon yarn and so between membrane layer, and the corrugated buffer edge also can be processed in diaphragm ring limit.
The present invention adopts the operating principle of stealthy whole button pressure relief mechanism as follows:
Stealthy whole button cover, sheet metal punch forming one similar water bowl cover shape for similar stainless steel-like, the smooth dimpling of its end face, and wall adheres to the flexible material of one deck rubber cushion or epoxy resin and so within it, form rubber-like outer rigid inner soft type compound button, its diameter and water-inflow and drain valve seat are complementary, formation has larger area strain face, push whole button cover, its end face middle part cover is easy to depression and advances a small distance, the stroke degree of depth can reach 0.2 centimetre, and the trip T-shape relief valve that is enough to link is opened.During no external force, whole button cover is recovered the free state of dimpling, awaits orders.So-called " stealth " both do not had the diametric plane gap of obvious button projection and stroke, but utilize the concavo-convex strain of cover, finish pressure release and start, so the similar whole button cover that adopts other plastic material to make is feasible equally, and can increase cartoon pattern etc., feel is refreshing.
