Model utility content
The utility model has overcome deficiency of the prior art, and provides a kind of volume little, and enter side and goes out magnetic force valve plug of time-delay valve at the small-sized end that suitability is wider.
The purpose of this utility model is achieved in the following ways.
Enter side and go out magnetic force valve plug of time-delay valve at the small-sized end, there is valve body, the top of valve body is provided with magnetic valve structure, the middle part of valve body is housing structure, piston is housed in cylinder body, this piston consists of the sealing head of head, bar portion and lower end, and the end face of piston crown and magnetic valve bottom form water storage cavity, also have time delay water hole be communicated with water-inlet cavity and water storage cavity at piston crown; In described magnetic valve, be provided with pusher over against the pressure release via arrangement of piston head, magnetic post is equipped with at the top of pusher, and gasket seal is equipped with in the lower end of slide bar, between piston head and magnetic valve bottom, return spring is housed,
The bottom of described valve body is provided with base plate, the import of inlet channel is opened on the base plate of valve body, and base plate top has water outlet to open the water outlet on the surrounding sidewall of valve body, and there is water-inlet cavity at valve body middle part, surrounding is pressure-releasing chamber, rubber seal and base plate is housed on the sealing head of piston lower end and forms lower limit sealing.
Like this, inlet channel is opened on base plate, and base plate top is water outlet, has saved in background technique and by arc-shaped partition and back-up ring structure, valve body lower portion cavity has been cut apart and formed inlet channel and this structure of water outlet, simplify valve body lower portion structure, reduced valve body lower portion height.The opening relative position that has simultaneously also changed water intake and water outlet, water intake is arranged on base plate center, place water inlet, water outlet is positioned at water intake periphery, makes like this water feeding pressure less than the hydraulic pressure producing from surrounding water inlet, and the water yield is also few.In the situation that inflow, hydraulic pressure reduce, on valve body surrounding sidewall, set out the mouth of a river, increased the quantity of water outlet, increased moment water displacement, not only economize on water but also do not weaken impulse force, guaranteed flushing effect.
Described water-inlet cavity is that in piston rod portion, cavities forms, and water-inlet cavity is communicated with inlet channel, and the outer wall of bar portion and inboard wall of cylinder block form pressure-releasing chamber; In the center of piston, have axial pressure release through hole, be communicated with pressure-releasing chamber.
Like this, the water-inlet cavity in the middle of piston rod portion is divided into cylinder body middle part and the pressure-releasing chamber of surrounding, the y-type seal ring on the periphery of piston crown is between water storage cavity and pressure-releasing chamber, and piston rod portion is by y-type seal ring and water-inlet cavity isolation.Y-type seal ring is pressed on the water in water storage cavity.
In closing relief hole process, tap water enters water storage cavity by inlet channel, water-inlet cavity from time delay water hole, because water-inlet cavity cavity dwindles, only need a small amount of water to enter water-inlet cavity from inlet channel, by time delay hole, fill with water to water storage cavity within a short period of time, along with hydraulic pressure increases gradually, makes piston time delay progressively move down last rubber seal and contact the flushing valve of formation hermetically closing with water outlet import base plate under the hydraulic pressure of water storage cavity and the acting in conjunction of return spring.
Horn mouth is housed towards the open y-type seal ring of water storage cavity direction on the periphery of described piston crown, and is slidably connected with inboard wall of cylinder block.
Because y-type seal ring communicates with water storage cavity, when water storage cavity water storage, y-type seal ring is produced to down pressure.Along with water storage cavity is constantly intake, hydraulic pressure constantly increases, and now, water outlet is in negative pressure state, so Y-shaped ring horn mouth must be open towards the large water storage cavity direction of pressure, pressure is larger, and iiared port is larger, more sealing.Otherwise spool cannot be closed, and there will be water leakage phenomenon.
Working procedure of the present utility model is:
When bath, press cup, promote magnet ring and move downward, under the effect of magnet ring, the moving pusher of magnetic cornice moves upward, thereby open pressure release through hole, after the water pressure release in water storage cavity, externally under the Water Pressure of water-inlet cavity, promotion piston lifts, the sealing head of piston lower end and rubber seal are lifted and are detached water channel import, have opened flushing valve, and inlet channel is communicated with and washes by water with water outlet.Hand unclamps after cup, under the effect of Returnning spring, magnet ring is moved upward, under the effect of magnet ring, promote the moving pusher of magnetic cornice and move downward, close pressure release through hole, tap water enters water storage cavity by inlet channel, water-inlet cavity from time delay water hole, increase gradually hydraulic pressure, under the hydraulic pressure of water storage cavity and the acting in conjunction of return spring, make piston time delay progressively move down last rubber seal and contact the flushing valve of formation hermetically closing with water outlet import base plate.
Though the current of the utility model and background technique spool are all to enter side in the end to go out, there is significantly difference in structure.1, the utility model has changed valve body polycrystalline substance, makes to change into and out of water channel, has reduced the height of whole valve body; Moreover, changed the position of water intake and water outlet.By base plate center, one place intakes, than background technique from the surrounding more water-saving of intaking; 2, the water-inlet cavity in background technique is positioned at cylinder body surrounding, and y-type seal ring communicates with water-inlet cavity, during water inlet, with water-inlet cavity water level, rises, and current produce pressure from surrounding to y-type seal ring, so y-type seal ring horn mouth downward (opening to water-inlet cavity direction); The utility model water-inlet cavity is positioned at cylinder body middle part, is around pressure-releasing chamber, and y-type seal ring communicates with water storage cavity (Fig. 3), and current enter water storage cavity from cylinder body middle part through time delay hole, and y-type seal ring is produced to down pressure.Because y-type seal ring bears the variation of the direction of hydraulic pressure, for fear of the poorly sealed water leakage phenomenon that causes, y-type seal ring horn mouth is changed into upwards.And when water storage cavity water storage, water outlet is in negative pressure state, so Y-shaped ring horn mouth must be open towards the large water storage cavity direction of pressure, pressure is larger, and iiared port is larger, more sealing.Otherwise spool cannot be closed, and there will be water leakage phenomenon.
In sum, the utility model has changed valve core inside structure, has reduced spool height, has reduced valve core inside space, and whole spool volume is obviously reduced, and can be suitable for being arranged on the tap of little individuality using, and has expanded using scope.Suitability is stronger, and structure is simpler, has saved material, and it is also easier to assemble, and water more economizes, and water storage and bath time are ofer short duration.
