Background technique
Water resource pollution is more and more serious now, and urban water safety problem is particularly serious.For the secondary pollution problem of tap water and former water pollutions and the harmful matter existed in tap water, increasing water purifying plant is applied.Water purifying plant in use for some time pipeline, equipment can cause secondary pollution, and filter core is as the most crucial parts of water purifying plant, and reverse osmosis state of filter element directly affects the quality of water outlet, so periodic replacement is absolutely necessary.
Therefore, there is the water purifying plant of many removable purifying filter element assemblies on the market.Disclose a kind of ready-package water purifier with double self locking sealing as the application number Chinese patent that is 201110170356.6 and comprise its filter plant, it comprises the connection end and purifying filter element assembly that are provided with double self locking seal arrangement, wherein, described double self locking seal arrangement is made up of spool, seal ring, valve seat and ejector spring, the inside of wherein said spool hollows out formation collect cavity, and forms through hole on described collect cavity sidewall; Described ejector spring is loaded in the collect cavity of described spool; The bottom of described spool and valve seat taper fit; Described seal ring is loaded in the seal groove of described spool bottom centrum; Described double self locking seal arrangement loads from the inside of connection end, to be fixed to be connected by valve seat with the end cap shell of connection end.It is intake in collect cavity by the through hole on collect cavity sidewall, and when element kit is dismantled, the effect by the hydraulic pressure in the elastic force of spring and collect cavity makes spool and valve seat lock sealing, reaches the effect of closing water inlet.Inlet through hole due to collect cavity is opened on sidewall, hydraulic pressure some be distributed to side, effectively cannot make spool and valve seat lock sealing, change element kit time still there is infiltration phenomenon.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of structure simple, hydraulic pressure can be pressed down the double self locking sealed valve of spool from Vertical direction.
For this reason, the technical solution of the utility model is: a kind of double self locking sealed valve, comprises spool, seal ring, valve seat and spring; The inside of described spool hollows out formation collect cavity, and the bottom of described spool has cone, with valve seat taper fit; Described seal ring is loaded in the seal groove of described spool bottom cone; It is characterized in that: it also comprises a valve gap, described valve gap entirety is cirque structure, has some buckles below annulus; A spring fixed column is fixed with by quarter butt in the middle of the annulus of described valve gap; Described spring one end is placed in the collect cavity of spool, and the other end is enclosed within the spring fixed column in the middle of valve gap; Described valve seat lower end has the tapered opening matched with spool bottom cone, and upper end is hollow cylinder; The circumferential surface of described hollow cylinder have some rectangular apertures; Described spool is placed in the hollow cylinder of valve seat; Described valve gap is arranged on valve seat upper end, and the buckle below valve gap and valve seat rectangular aperture circumferentially engages.
Further, the outer wall of described spool collect cavity has some stiffening ribs, the inwall of described valve seat has some slender type grooves; Stiffening rib outside described spool collect cavity inserts in the slender type groove of valve base inner wall; The quantity of the stiffening rib outside described spool collect cavity and the slender type groove of valve base inner wall and position one_to_one corresponding; The quantity of the buckle below described valve gap and valve seat rectangular aperture circumferentially and position one_to_one corresponding.
Further, the stiffening rib outside described spool collect cavity is divided into three groups, often organizes three, by spool collect cavity trisection; The slender type groove of described valve base inner wall has three, and spool collect cavity is often organized middle stiffening rib outward and inserted in the slender type groove of valve base inner wall; Described valve seat rectangular aperture circumferentially has three, is positioned between two in the middle of slender type groove; Buckle below described valve gap and valve seat rectangular aperture is circumferentially corresponding.
The utility model is arranged on the water outlet of water purifying plant filter flask, and lower end is filter flask, and upper end is water outlet mouthpiece.During normal work, after water to be filtered enters filtration from filter flask water intake, flow to the water outlet of filter flask continuously, make the pressure of water outlet become large, when the elastic force of spring above hydraulic pressure is greater than spool, spool can up lifting gradually under the effect of hydraulic pressure, lift off a seat gradually, water cut off device is opened, and current flow through from the stiffening rib of spool collect cavity outer wall and the gap of valve base inner wall, water outlet mouthpiece is flow to, normal water flowing from circular valve gap; When dismantling filter flask, the hydraulic pressure below spool is decreased to zero, and spool is subject to the top elastic force of spring and the residual hydraulic pressure effect of water outlet mouthpiece is pressed in valve seat bottom, automatic water seal firmly.Sealed valve of the present utility model is independently component, after outside Batch assemblage is good, directly can puts into the water outlet of water purifying plant, realize self-locking seal function, is extremely convenient to install and change; Meanwhile, the water at water outlet mouthpiece place enters collect cavity from valve gap upper vertical, exerts pressure downwards, coordinates and makes spool and valve seat lock sealing, reach the effect of automatic water seal with spring.
