Description

The porcelain core float valve

Technical field

The utility model belongs to valve, relates to the improvement of float valve in the cleaners and polishes toilet flush, provides a kind of ball float porcelain core float valve that swing in smaller angle, good seal performance.

Background technique

Tank ball-float valve in the flush toilet of prior art, dumb because of the motion of floating ball rod, poppet shaft, Sealing is opened to close and is closed not in place being easy to generate and leak, and perhaps aging, the abrasion deformation because of Sealing rubber also causes and leaks.In addition, there is opening angle big (reaching 90 °) in the utility model patent ZL00245564.1 Magnetic-core float valve of the design people's cooperation design, has motion dead angle, ball float and connecting rod to need big defectives such as space.

The model utility content

The utility model provides a kind of improved porcelain core float valve, and its ball float and link motion pivot angle are little, and the porcelain core opening angle is little, does not have the motion dead angle, Sealing is wear-resistant anti-aging not water clock.

The utility model porcelain core float valve comprises ball float, floating ball rod, following valve body, poppet shaft is contained in the upper valve body, upper valve body is stretched out on the top of one poppet shaft, with floating ball rod directly or be fixedly connected on the top of poppet shaft with the connecting shaft cap, the upper valve body sidewall has pod apertures, lower end mouth is fluted, and the inwall hypomere has block; Poppet shaft lower end surface outer edge has and is 120 ° of three uniform projectioies; One has the rotation porcelain spool of three covering of the fans, embeds three projectioies of poppet shaft with three grooves of its covering of the fan upper surface; One has the fixedly porcelain spool in three fan holes, embed with the projection on its cylndrical surface in the groove of upper valve body lower end surface, rotate the lower surface of porcelain spool and be close to the fixing upper surface of porcelain spool, the upper valve body of finishing above-mentioned assembling adds that sealing gasket and following valve body general assembly are integral.

In the design's porcelain core float valve, rotate three covering of the fans of porcelain spool fan-shaped correspondence central angle and fixedly the central angle of the fan-shaped correspondence in three fans of porcelain spool hole equate, and in 30 °-45 °, select for use, and the central angle overgauge of covering of the fan, the central angle negative deviation in fan hole.It is fan-shaped that perhaps the fan-shaped central angle of covering of the fan is slightly larger than the fan hole.

The ball float and the link motion pivot angle of the design's porcelain core float valve are little, and it is little to take up room, and do not have the motion dead angle, and the porcelain spool is wear-resistant and good seal performance, have prolonged life of valve and economize on water because of no water clock.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 rotates porcelain spool plan view.

Fig. 4 is fixing porcelain spool plan view.

Embodiment

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described in further detail.

Explanation rotation porcelain spool and fixedly the shape structure and the design feature of porcelain spool earlier.Referring to Fig. 3, the rotation porcelain spool 5 among Fig. 1 is a ceramic plate, overlooks as fan blade, and three uniform sectors 51 are arranged, blade upper surface outer fluted 53.Fig. 4 is the fixing shape of porcelain spool 6 among Fig. 1, is roughly circular ceramic plate, and its diameter equates with the outside diameter of rotation porcelain spool 5.Three uniform fan shaped boreholes 61 are arranged in the sheet.By on the outside cylndrical surface of fan shaped borehole 61 three projectioies 63 being arranged.It is equal to rotate the corresponding central angle of the central angle of porcelain spool sector 51 correspondences and fixing porcelain spool fan shaped borehole 61, selects for use in 30 ° of-45 ° of scopes.Sector 51 is an overgauge, and fan shaped borehole 61 is a negative deviation.Perhaps the central angle of sector 51 is slightly larger than fan shaped borehole 61.Rotate porcelain spool 5 and fixing porcelain spool 6 overlapping after, sector 51 should cover fan shaped borehole 61 fully, it is water-tight to reach sealing surface.

An example of porcelain core float valve as depicted in figs. 1 and 2.Poppet shaft 2 is put in the tubular upper valve body 4 of cardinal principle, and stretch out from upper valve body 4 end faces on the top of poppet shaft 2, floating ball rod 1 is fixedly connected on the top of poppet shaft 2 by connecting shaft cap 11.Perhaps without connecting shaft cap 11, the two directly links to each other.Be contained in expression among the ball float figure of floating ball rod 1 the other end.The sidewall of upper valve body 4 has pod apertures 10, and the lower end surface is fluted 9, and the inwall lower end mouth has block 12.Poppet shaft 2 lower end surface outer edges have and are 120 ° of three uniform projectioies 14, will rotate three grooves 53 of porcelain spool 5 upper surfaces and three projection 14 tablings of poppet shaft 2 lower end surfaces, in the groove 9 with fixing projection 63 embedding upper valve bodies 4 lower end surfaces of porcelain spool 6.Rotate the lower surface of porcelain spool 5 and fixedly the upper surface of porcelain spool 6 be close to.Between the port of the convex shoulder of upper valve body 4 and following valve body 8, add sealing gasket 3 then, between the bottom surface of the lower end mouth of upper valve body 4 and following valve body 8, add sealing gasket 7, the upper valve body 4 that has assembled is fixedlyed connected with following valve body 8 be integral.

The design's porcelain core float valve has two kinds of typicalnesses when using.When ball float floats in the extreme higher position, to rotate the covering of the fan 51 of porcelain spool 5 and overlaps with the fixing fan hole 61 of porcelain spool 6, interrupt because of 61 sealings of fan hole in the water route, and at this moment the interior block 12 of upper valve body 4 lower end mouth has limited the slip of rotation porcelain spool 5.After water in the water tank uses, ball float sinks down into extreme lower position, floating ball rod 1 drives by poppet shaft 2 and rotates porcelain spool 5 rotation together, during block 12 places in forwarding upper valve body to, rotate porcelain spool 5 and stop to slide, open fully in fan hole 61, water is entered by a side (as the right side) of following valve body 8, pass fan hole 61, enter down valve body 8 opposite sides (as the left side) pipeline by the pod apertures 10 on upper valve body 4 sidewalls again, then enter and to fill with water tank standby.The design's porcelain core float valve floating ball rod pendulum angle is 0 °-45 °.
