Description
The utility model belongs to the self-closing valve of a kind of liquid pressure conduit, especially for the flushing valve of large and small just sanitary apparatus flushing.
In the large and small just sanitary apparatus flusher that uses, having a kind of is the core-skin valve at present, and another kind is flushing valve, and the former is not owing to having self-closing function, so water resource waste is big; The latter can not control water yield size, and delay time is long, during low pressure, can not close automatically, and time-delay length is subjected to the influence of pipeline variation in water pressure.
It is a kind of simple in structure that the purpose of the utility model is to provide, and closing velocity is steady, can prevent the hydraulic pressure time-delay automatic flushing valve that dirty gas instead overflows.
The hydraulic pressure delay-self-closing flush valve is fixed on the valve gap on the valve body by the valve body that has turnover water channel, control chamber, places the mechanism for opening/closing that surges in valve gap and the valve body to form.The mechanism for opening/closing that surges comprises: place the piston in the valve body control chamber, be fixed on seat ring, the diaphragm seal of piston bottom end, be contained in valve rod, spring in the valve gap, be enclosed within the water filling cavity that outer button that is connected with valve stem tip of valve gap and valve gap and piston form; Have time-delay hole and Baltimore groove on the valve plug, bottom land has spilled water hole, the sluicing bar that the control spilled water hole opens and closes is housed in the groove, be with successively on the sluicing bar and recover spring, ring washer, jump ring, in water filling cavity, between sluicing bar and the valve rod shifting block is housed, when pressing ovable valve stem, shifting block can touch the sluicing bar.
Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The hydraulic pressure delay-self-closing flush valve is by valve body 26, is fixed on valve gap 15 on the valve body 26 with lock nut 12, places the mechanism for opening/closing that surge in valve gap 15 and the valve body 26 to form.
Valve body 26 comprises inlet channel, water outlet, control chamber, and the angle α between control chamber and the inlet channel is 70 °, and the valve on the turnover water channel is relative with control chamber, also becomes the inclined-plane, and itself and horizontal plane angle are 20 °.Be filled with sealing ring 13 between valve body 26 and the valve gap 15.
The mechanism for opening/closing that surges comprises: place the valve plug 24 in valve body 26 control chambers, valve plug 24 is " T " font, and its central upper portion has groove, and the bottom is fixing with seat ring 8, diaphragm seal 7 with guiding fork 6, and guiding fork 6 is stretched on valve, and slippage thereon; Bottom portion of groove has spilled water hole 9, and 0 shape sealing ring, the 25 sluicing bars 27 that control spilled water hole 9 opens and closes are housed in the groove, is with successively on the sluicing bar 27 and recovers spring 28, ring washer 22, jump ring 21, and jump ring 21 is embedded in the groove inwall ring recess.Valve plug 24 outer walls are with leather cup 23, and valve plug 24 tops have time-delay hole 11, and time-delay is equipped with filter screen 10 on the hole 11.It is the valve rod 17 of taper that the bottom is housed in valve gap, is with spring 18 on the valve rod 17, and an end of spring 18 has and is connected with valve rod 17 tops and is enclosed within the outer button 19 of valve gap 15, between valve rod 17 and the valve gap 15 sealing ring 20 is arranged.In the water filling cavity 14 that valve gap 15 and piston 24 form, between sluicing bar 27 and the valve rod 17 shifting block 16 is housed, this shifting block 16 make with valve rod 17 taper inclined-planes complementary mutually carve piece, when pressing ovable valve stem 17, shifting block 16 can touch 27 inclinations of sluicing bar.
Valve body 26 is equipped with the anti-fouler that antifouling gas instead overflows on water outlet, this device ring washer 5, O-ring seals 4 are housed on the water outlet successively and be the core retainer plate 1 of garden platform shape and roof pressure on core retainer plate 1 and the dirt proof sleeve 3 that is threaded with delivery port; Have the mudhole 2 that communicates with atmosphere on dirt proof sleeve 3 center side walls.When valve body 26 was closed, the anti-bromine gas that overflows was discharged by the mudhole on the dirt proof sleeve 32.
The utility model in use, its operating principle is such: before the flushing, because the fluid pressure of pipeline, water enters in the water filling cavity 14 from time-delay hole 11, because of piston 24 upper surface area greater than the soffit area, piston 24 moves from top to bottom, valve is in close valve state.During flushing, press the button 19, valve rod 17 forces shifting block 16 to touch 27 inclinations of sluicing bar, and the water in the water filling cavity 14 is excreted in the water outlet, by spilled water hole 19 at this moment, the fluid pressure of water filling cavity 14 reduces, piston 24 moves up, and valve open is because the effect of back-moving spring 28, sluicing bar 27 resets, so liquid can not flow into from spilled water hole 9 in the water filling cavity 14; But liquid enters water filling cavity 14 from time-delay hole 11, and along with the increase piston 24 of water in the water filling cavity 14 moves down, valve is closed gradually, thereby reaches the purpose of delay-self-closing.
Obviously, the utlity model has simple to operately, installation and maintenance are convenient, close Close the advantages such as steady, also can instead overflow by antifouling gas, can be widely used in family, hotel, On the stool, urine sanitary apparatus such as school.
