Description
Technical field
The utility model relates to a kind of valve fittings, relates in particular to a kind of four-sided valve of sealing configuration, belongs to reverse osmosis water treating equipment field.
Background technique
Four-sided valve comprises two feed-water ends, two waterexit ends.As Figure 1-Figure 5, the hydraulic pressure control eardrum by a feed-water end (being ring low pressure eardrum 7 in conventional inside) thus be delivered to the eardrum (i.e. ring low pressure eardrum 4 in tradition outside) of another feed-water end, thereby the circulation status in control water route.Conventionally the four-sided valve using is that the Transfer Medium between two-layer eardrum is replaced by and is more suitable for the material that contacts with eardrum mostly, changes material or the structure of ring in size, thereby changes the working environment of eardrum.In actual moving process, find traditional in two groove 10 parts of eardrum, to there will be the phenomenon of leaking, reason is that the recess between edge projection 11 parts and upper cover 2 and imperial palace ring 3 is poorly sealed, thereby make current drain to the side chamber between upper cover 2 madial walls and imperial palace ring 3 outer side walls, even occur the phenomenon of pressure release.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of good airproof performance is provided, prevent that four-sided valve from leaking, the four-sided valve of the sealing configuration of pressure release, solve traditional four-sided valve and there will be and leak at two groove parts of eardrum, even occurred the problem of pressure release phenomenon.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of four-sided valve of sealing configuration, comprise upper cover, upper cover is connected with lower cover below, the left and right sides of upper cover is respectively equipped with upper cover water intake and upper cover water outlet, the left and right sides of lower cover is respectively equipped with lower cover water intake and lower cover water outlet, the centre of upper cover is provided with water-inlet cavity, below water-inlet cavity, be provided with ring low pressure eardrum in inner side, inner side interior ring low pressure eardrum passes through the little interior ring below it, imperial palace ring is connected with ring low pressure eardrum in outside, in little, be located on the centre of imperial palace ring, it is characterized in that, in described inner side, ring low pressure eardrum outermost is provided with inner side grab, in outside, ring low pressure eardrum outermost is provided with outside grab.
Preferably, the shape of described inner side grab and outside grab is inverted "L" shaped shape.
Preferably, one side between the madial wall of being located at upper cover of described inner side grab and the outer side wall of imperial palace ring.
Preferably, one side between the madial wall of being located at upper cover and the projection of lower cover of described outside grab.
Preferably, the pore size of described water-inlet cavity is 6-10mm.
The utility model, on the basis of traditional four-sided valve structure, has changed the structure of encircling low pressure eardrum in outside in ring low pressure eardrum and inner side, encircles the outermost of encircling low pressure eardrum in low pressure eardrum and inner side and use respectively inverted L shape sealing configuration in outside.Even having between original edge projection part and upper and lower covers and imperial palace ring poorly sealed in the situation that, also can guarantee that whole system exists the state sealing, good airproof performance, can not cause the phenomenon of current side leakage and pressure release.The aperture of the water-inlet cavity of the aperture ratio tradition four-sided valve of the water-inlet cavity in the upper cover of four-sided valve provided by the utility model (structure as shown in the figure) is little, thereby improves the using scope of intake pressure.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The utility model is a kind of four-sided valve of sealing configuration, as shown in Figure 6, Figure 7, it comprises upper cover 2, upper cover 2 is connected with lower cover 5 below, there are respectively upper cover water intake 2-1 and upper cover water outlet 2-1 in the left and right sides of upper cover 2, there are respectively lower cover water intake 5-2 and lower cover water outlet 5-1 in the left and right sides of lower cover 5, and there is water-inlet cavity 1 centre of upper cover 2, and the pore size of water-inlet cavity 1 is 6-10mm.Water-inlet cavity 1 has ring low pressure eardrum 9 in inner side below, in inner side, ring low pressure eardrum 9 is connected with ring low pressure eardrum 8 in outside by little interior ring 6, imperial palace ring 3 below it, little interior ring 6 is arranged on the centre of imperial palace ring 3, the middle interfix of inserting little interior ring 6 of ring low pressure eardrum 8 in ring low pressure eardrum 9 and outside in inner side, in inner side, ring low pressure eardrum 9 outermost have inner side grab 9-1, and in outside, ring low pressure eardrum 8 outermost have outside grab 8-1.The shape of inner side grab 9-1 and outside grab 8-1 is inverted "L" shaped shape.One side of inner side grab 9-1 is between the madial wall of upper cover 2 and the outer side wall of imperial palace ring 3, and inner side grab 9-1 is wrapped in imperial palace ring 3 in it and covers.One side of outside grab 8-1 is between the madial wall of upper cover 2 and the protruding 5-3 of lower cover 5, and in outside, ring low pressure eardrum 8 is stuck on protruding 5-3 by outside grab 8-1.
The utility model has changed the structure of encircling low pressure eardrum 9 in outside in ring low pressure eardrum 8 and inner side, encircles the outermost of encircling low pressure eardrum 9 in low pressure eardrum 8 and inner side and use respectively inverted L shape sealing configuration in outside.Even if having between original edge projection 11 parts and upper and lower covers and imperial palace ring 3 poorly sealed in the situation that, also can to upper and lower covers and imperial palace ring 3, seal by outside grab 8-1 and inner side grab 9-1, guarantee that whole system exists the state of sealing, can not cause the phenomenon of current side leakage and pressure release.
In addition on the one hand, the working principle of considering four-sided valve is that the pressure by a water route is applied to the other end eardrum by medium, thereby controls the dissengaged positions of current.The aperture (general water-inlet cavity aperture is 11mm) of the water-inlet cavity that ratio that the utility model is opened the aperture of the water-inlet cavity in upper cover 21 is general is little.Under the flow velocity of the water condition identical with hydraulic pressure, the little pressure in aperture is greater than the large pressure in aperture.Thereby increase pressure by reducing the water flowing aperture of water-inlet cavity.By reducing aperture, thereby improve the using scope of intake pressure.
