Abstract
The utility model relates to a sealing pad for water taps, which belongs to a mechanical part. The purpose of the utility model is to design a leakage-proof long service life sealing pad for water taps in order to replace the present widely used general rubber sealing pad. Because of the relationship of stress fatigue, the latter has a shorter service life and easily produces a water leakage phenomenon. Thepurpose of the sealing pad for water taps is the surface of the inner hole of the general annular sealing pad (3) is provided with a sealing edge (1); the sealing edge (1) bears a sealing function to reduce the internal stress of the sealing pad. In order to make installation convenient and increase the activity space of the sealing edge (1), the bottom of the sealing pad is provided with a groove (2).
Description
A kind of water tap sealing gasket belongs to mechanical parts.
Common water tap as shown in Figure 2.When rotatory handling (6), lifting screw (5) just moves up and down, and water is flowed out or ends.Because water can upwards come up along lifting screw (5), should use proper method to be sealed herein.
Existing encapsulating method has two kinds.The one, filled stone cotton cord in seal groove around the lifting screw (5), the 2nd, go up the packing ring (3) that overlaps a rubber system at lifting screw (5), use nut (4) to compress then.First kind of mode is because asbestos are harmful, and sealing effect is not good, is eliminated gradually.What extensively adopt at present is the second way.
This mode is that the rubber washer (3) of internal diameter less than the lifting screw diameter tightly is enclosed within on the lifting screw (5).Because when assembling and during use, this packing ring is in the stress stress state that is stretched all the time, because of fatigue causes flexibility decrease, influences sealing effect easily, and often use just produces water leakage phenomenon soon.
The purpose of this utility model is a design long novel seal pad in a kind of working life, improves the seepy question of water tap.
The utility model is a kind of ring-shaped rubber sealing gasket, and its sectional drawing as shown in Figure 1.Its global shape is similar with existing ring-shaped rubber packing ring (3), this packing ring totally ringwise, annular inboard is higher than the outside, its sectional shape is the compound of subtriangular and rectangle, its major character is to increase sealing along (1) at the rubber washer bore area, the width on this sealing edge (1) and highly all very little, seal action can be played in it and lifting screw Elastic Contact.Because sealing function is born along (1) by sealing, the internal diameter size of rubber washer can suitably increase, the internal stress during with minimizing work.For convenience of assembling and the move place that in use increases sealing edge (1), reduce its stress tension intensity, have annular groove (2) in the bottom surface of rubber washer.The cross section of groove (2) can be V-shaped.
In water tap, replace existing rubber washer through test, because internal diameter is bigger, easy for installation laborsaving with the utility model.Because internal stress is less during work, working life and seal degree all improve a lot.
Sealing edge (1) can be located at the bore area bottom of rubber washer (3), and sealing gasket is made once-through with rubber or other elastic materials.
Fig. 1 is that the utility model is along the diametric(al) sectional drawing.(3)-rubber washer among the figure, (1)-sealing edge, (2)-groove.
Fig. 2 is existing structure for water tap schematic representation.(5)-lifting screw among the figure, (4)-nut, (3)-rubber washer.
Embodiment: for the rubber washer of external diameter 25mm internal diameter 15mm, sealing is 0.5mm-3mm along the width of (1), and the width of groove (2) is 1.5mm-2.5mm.
Claims (2)
1. a water tap sealing gasket that prevents to leak from the grip totally ringwise, outside annular inboard is higher than, is characterized in that an annular seal being arranged along (1) at sealing pad bore area.
2. water tap sealing gasket according to claim 1 is characterized in that the rebasing face of sealing has annular ditch groove (2), and the cross section of this groove is V-shaped.
