Abstract
The utility model discloses a valve core for water taps. The utility model is still composed of a valve rod, a valve cover, an O-shaped sealing ring, a clamping spring, an abrasion-proof gasket, a guiding gasket, a ceramic sealing sheet and a sealing gasket. The utility model is characterized in that a positioning block is formed on the valve rod, the position in the valve cover corresponding the positioning block is fixedly provided with a ring sheet, the ring sheet is symmetrically provided with two stopping blocks, the positioning block is matched with the stopping blocks arranged on the ring sheet, and the switch angle of the valve core is from 90 +1 DEG to 90-1 DEG is ensured. The valve core for water taps has the advantages of reasonable material, accurate positioning, good torsion-resistant performance, guarantee of the valve core performance, long service life, reliable sealing and low cost.
Description
The utility model relates to a kind of faucet valve core.
At present, ceramic plate seal tap spool commonly used has two kinds, and a kind of valve gap of spool and valve rod are to be processed by brass, and brass material cost height, weight are big, processing difficulties, the difficult control of dimensional accuracy, difficult quality are grasped; The valve gap and the valve rod of another kind of spool are to be processed by the plastic cement injection moulding, valve gap and valve rod intensity are all poor, resistance to torsion is poor, fracture easily takes place wait inefficacy, working life is short, and no positioning block connection between valve rod and the valve gap is by the positioning block on valve gap top and the external world location that joins, owing to be indirect addressing, cause location and using effect not good.
The purpose of this utility model is to provide a kind of faucet valve core, and its accurate positioning can guarantee the spool performance, and cost is low.
For achieving the above object, the utility model still is made up of valve rod, valve gap, " O " RunddichtringO, jump ring, wear-resistant pad, guiding pad, ceramic seal gasket, sealing gasket, its key is to form a positioning block on the valve rod, the fixed-site of corresponding positioning block is provided with a ring plate in the valve gap, symmetry has two blocks on the ring plate, positioning block cooperates with block in the ring plate, and the angle that can guarantee switching spool is 90 ± 1 degree.
And the following ora terminalis of sealing gasket outwards protrudes and forms a boss, so that itself and valve gap lower end closely cooperate, has good seal; The upper-end surface of sealing gasket also forms an annular groove, so that itself and ceramic seal gasket below closely cooperates, further strengthens obturation effect.
After adopting said structure, the utility model valve gap can be plastic cement material, and valve rod, ring plate can be metallic material, and the metal ring plate embeds in the valve gap, the valve rod valve gap of packing into, between ring plate and valve rod wear-resistant pad is arranged, ring plate is fixed in the valve gap, and the valve rod cylindrical has positioning block to cooperate with the block of ring plate, valve rod can only carry out the right angle and rotate, because what adopt is positioned internal, accurate positioning is reasonable, has guaranteed the spool performance; And valve gap to adopt plastic cement be material, cost is low, dimensional accuracy, surface roughness can accurately be controlled, valve rod adopts copper (or stainless steel), but proof strength is bumped into the metal ring plate and both can guarantees block intensity in the valve gap, can guarantee the not direct and valve gap effect of valve rod again, resistance to torsion is good, long service life; Valve rod and valve cover chamber add wear-resistant pad and had both guaranteed wear resistance, can produce the lighter effect of feel again.
Below in conjunction with drawings and Examples, the utility model done describing in further detail.
Fig. 1 is the utility model three-dimensional exploded view;
Fig. 2 is the utility model combination schematic representation;
Fig. 3 be among Fig. 2 A-A to sectional view.
See also shown in Fig. 1-2, the utility model is identical with the spool of prior art, still by valve rod 1, valve gap 2, " O " RunddichtringO 3, jump ring 4, wear-resistant pad 5, guiding pad 6, ceramic seal gasket 7,7 ', sealing gasket 8 forms, this paper will not give unnecessary details.
The key of this case is: form a positioning block 11 on the valve rod 1, the fixed-site of corresponding positioning block 11 is provided with a ring plate 9 in the valve gap 2, equal symmetry has two blocks 21,91 on valve gap 2 and the ring plate 9, wherein, valve gap 2 can be plastic cement material, valve rod 1, ring plate 9 can be metallic material, positioning block 11 cooperates with block 91 in the ring plate 9, making valve rod 1 can only carry out the right angle rotates, the position structure schematic representation that cooperates the utility model valve rod 1 shown in Figure 3, ring plate 9 and valve gap 2, the angle that has guaranteed switching spool is 90 ± 1 degree, and accurate positioning is reasonable.
And the following ora terminalis of sealing gasket 8 outwards protrudes formation one boss 81, and itself and valve gap 2 lower ends are closely cooperated, and has good seal; The upper-end surface of sealing gasket 8 also forms an annular groove 82, makes itself and ceramic seal gasket 7 ' closely cooperate, and further strengthens obturation effect.
Claims (2)
1, a kind of faucet valve core, form by valve rod, valve gap, " O " RunddichtringO, jump ring, wear-resistant pad, guiding pad, ceramic seal gasket, sealing gasket, it is characterized in that: form a positioning block on the valve rod, the fixed-site of corresponding positioning block is provided with a ring plate in the valve gap, symmetry has two blocks on the ring plate, and positioning block just can cooperate with the block in the ring plate.
2, a kind of faucet valve core as claimed in claim 1 is characterized in that: the following ora terminalis of sealing gasket outwards protrudes and forms a boss, and the upper-end surface of sealing gasket also forms an annular groove.
