Abstract
The utility model discloses a time-delay self-closing flushing valve for a closet, which comprises a pressing device, a valve rod, a valve core and a sealing core. The sealing core is arranged at the middle upper portion of the valve core. The sealing core is sleeved on the top head of the valve rod. The top head of the valve rod is in a clearance fit and connection with the sealing core. The sealing core is tightly connected with the valve core. The bottom of the valve core is equipped with a time-delay spring corresponding to a water inlet hole. According to the structure of the flushing valve, a conventional flushing valve is additionally equipped with a sealing core. When the flushing valve is in use, a rubber ring inside the sealing core is pushed by the valve rod, so that the water in a pressure chamber is discharged for pressure release. Therefore, the valve core is pushed downward by the pressing device more easily and more quickly. Meanwhile, the structure of the flushing valve is additionally equipped with the time-delay spring. During the self-closing process of the flushing valve, the time-delay spring moves up and down in the water inlet hole. As a result, the obstruction of the water inlet hole is effectively prevented and the stability of the time-delay period is ensured. Compared with conventional time-delay self-closing flushing valves, water is saved by one third for each year averagely by utilizing the flushing valve of the utility model.
Description
Technical field
The utility model relates to a kind of time-delay flushing valve.
Background technology
The structure that is used for the delay-self-closing flushing valve of toilet at present mostly is to be made of pressing device and valve rod and spool.Such delay-self-closing toilet flush valve in use, by press pressing device by handle, promote valve rod and do axially-movable, start spool and move down, intake antrum is communicated with water chamber, realize starting and wash; When the delay-self-closing toilet flush valve is self-closing, water inlet enters the balancing gate pit by the groove that communicates with intake antrum on the valve body balancing gate pit sidewall, the water-filled process in the space of balancing gate pit is the control delay time, when the Nei Shui of balancing gate pit to the elastic force sum of buoyancy and pressing device return spring during greater than the pressure of water outlet position water, the flushing valve of delay-self-closing closet is resetted by brute force and closes, and promptly finishes delay-self-closing.There is following defective in the flushing valve of the delay-self-closing closet of this kind structure: 1, owing to be subjected to that intake pressure is unsettled to be influenced, cause the self-closing delay time instability of flushing valve of delay-self-closing closet, i.e. the delay time influence that is stressed is bigger.2, the slotted eye of water inlet groove easily stops up, and very easily causes the fault of toilet.3, because the effect of hydraulic pressure in the balancing gate pit, cause operate pressing device by the time require great effort.4, owing to unreasonable structure, thereby the serious waste water resource.
The utility model content
The utility model purpose is to provide the flushing valve of the operation delay-self-closing closet that nimble, self-closing delay time is stablized, economized on water.
The utility model purpose is to realize like this, it comprises pressing device, valve rod and spool this delay-self-closing toilet flush valve, it is characterized in that it also comprises a sealed core, sealed core is located at the middle and upper part of spool, sealed core is sleeved on the top head of valve rod, for matched in clearance is connected, sealed core closely is connected with valve core chamber between the top head of valve rod and sealed core, and place, corresponding inlet opening, spool bottom is equiped with the time-delay spring.
The technological progress that the utility model is obtained: because this delay-self-closing toilet flush valve has increased by a sealed core on the original structure basis, in use, earlier by the cushion rubber in the valve rod promotion sealed core, water in the balancing gate pit is discharged pressure release, thereby not only make pressing device advance spool light and fast more downwards, along with the propelling of spool moves down, intake antrum and water chamber are communicated with, wash toilet, simultaneously under the effect of pressing device return spring and time-delay spring, spool begins from closed procedure, and by intake antrum through being located at the water inlet on the sealing shroud and being located at inlet opening water filling in pressure chamber on the sealing shroud, promptly regulate the pressure in the pressure chamber, when the pressure in the pressure chamber during slowly greater than the pressure of drain chamber, the finishing of spool from closed procedure.Because in the injecting process that is pressure chamber, the time-delay spring is up and down in the inlet opening, can prevent the obstruction of inlet opening effectively on the one hand, has guaranteed the stability of delay time on the other hand.Since structure of the present utility model, thereby also have significant water-saving result, to compare with existing delay-self-closing flushing valve, annual mean can economize on water 1/3.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
For further describing the utility model, be described further below in conjunction with accompanying drawing.
As shown in Figure 1, this delay-self-closing toilet flush valve comprises pressing device 1, valve rod 2 and spool, and it also comprises a sealed core, and sealed core is located at the middle and upper part of spool, and its sealed core closely is connected with valve core chamber.Sealed core is by sealed core body 3 and sealing ring 4 and press female 9 to constitute, sealed core body 3 is sleeved on the top head of valve rod 2, sealing ring 4 is located between the top head of pressing mother 9 and valve rod 2, and the gap is 0.8～1.5 millimeter between the top head of sealing ring 4 and valve rod 2, and present embodiment is 1 millimeter.Press mother 9 and spool to be fastenedly connected in one.Spool is made of sealing shroud 8, sealing bucket 6, sealing mat 5 and sealing time-delay pad 7,6 screw threads of sealing shroud 8 and sealing bucket closely are connected, sealing mat 5 is sleeved on the outside of the sealed core body 3 at sealing bucket 6 tops, and time-delay sealing mat 7 is sleeved on the sealing shroud 8 of sealing bucket 6 bottoms.Press female 9 to be threaded with 8 of the sealing shrouds of spool.Side at sealing shroud 8 is provided with inlet opening 11, is equipped with time-delay spring 10 in the inlet opening 11.
The course of work of the present utility model: in off position down, by sealing mat 5 and sealing ring 4, with water management in intake antrum and pressure chamber; When needing flushing, press pressing device 1, by pressing driving a valve rod 2, by 1 millimeter crack between valve rod 2 and the sealed core sealing place of sealing ring 4 is opened again, meanwhile, hydraulic pressure in the pressure chamber has obtained pressure release, promptly less than the pressure in the drain chamber, after opening sealing ring 4, continue to push pressing device 1 again, just by valve rod 2 drive sealed cores, sealing mat 5, sealing drum 6, sealing time-delay pad 7, sealing shroud 8 with axially to lower slider, simultaneously that intake antrum and water chamber is open-minded, water flows to delivery port by water inlet, has promptly realized the flushing of toilet; After pressing device 1 stops to push, the effect of pulling force and time-delay spring 10 by the return spring in the pressing device 1, begin to start spool from closed procedure, the inlet opening 11 of while through being located at sealing shroud 8 one sides and water inlet water filling in pressure chamber of being located on the sealing drum 6, promptly regulate the pressure in the pressure chamber, when the pressure in the pressure chamber during slowly greater than the pressure of drain chamber, the finishing of spool from closed procedure.
