Specific embodiment
As shown in Figure 1-3, high sealing stop valve, the valve deck 2 including valve body and on valve body 1 includes valve in valve body 1
Bar 3, valve core case 4 and the spool 5 on valve core case 4,3 upper end of valve rod pass through valve deck 2 and connect with external handwheel 6, and spool 5 wraps
Flap 51 and valve lid 52 are included, flap 51 acts on the boss 41 of valve core case 4, close between flap 51 and boss 41 in order to improve
Sealing property, 51 bottom of flap are equipped with sealing ring 23, include ball sealer 24 and sealing bur 25 on sealing ring 23, and boss 41 is corresponding
Ball groove 42 is equipped at 24 position of ball sealer, 42 inner surface of ball groove is stress surface 44,24 surface of ball sealer top corresponding with stress surface 44
The compressive plane 26 of press-fit, when flap 51 is pressed downward, in the meeting close-fitting insertion ball groove 42 of ball sealer 24 on flap 51, ball sealer
Stress surface 44 of 24 compressive plane 26 into ball groove 42 squeezes, so that the two patch is tighter, more preferably, boss 41 is corresponding for sealing effect
It seals and is equipped with thorn slot 43 at 25 position of bur, the outer surface for sealing bur 25 matches with the inner surface of thorn slot 43, and sealing ring
Several sealing burs 25 on 23 can be tightly inserted into thorn slot 43 in so that sealing ring 23 between boss 41 there is no
Gap.
Since the spool 5 inside existing shut-off valve inner valve body 1 blocks spool by the directly rotation rise and fall of valve rod 3
4 two sides water inlets 8 of seat and water outlet 9 communicate, and directly and then the rotation of valve rod 3 is tightly attached on valve core case 4 spool 5, will lead to valve
Core 5 causes to wear in rotation to valve core case 4 and 5 contact surface of spool, can wear sealing material between the two, reduces leakproofness
Can, so being equipped with central channel 53 on flap 51,3 lower end of valve rod is deducted in the central channel 53 of flap 51 by valve lid 52, valve
It is threadedly coupled between lid 52 and valve deck 2, since the diameter of 3 bottom of valve rod is greater than the diameter of 3 upper end of valve rod, so, 3 bottom of valve rod
Can be resisted by valve lid 52, prevent valve rod 3 from dropping out out of central channel 53, when needing to separate valve rod 3 with spool 5, then only need by
Valve lid 52 is rotated out of from flap 51.3 bottom of valve rod is equipped with bulge loop 7, and 53 inner wall of central channel is equipped with the bulge loop to match with bulge loop 7
Slot, since bulge loop 7 is rotatably located in bulge loop slot, so the rotation of valve rod 3 not will drive the rotation of spool 5.1 left and right sides of valve body
It is respectively equipped with water inlet 8 and water outlet 9.
In order to prevent the rotation of valve rod 3 or stress and deform and fracture, fixed valve rod 3 is equipped between valve deck 2 and valve rod 3
Connecting rod 10, connecting rod 10 are in Curved, and 10 upper end of connecting rod is equipped with thread bush 11, and 11 sets of thread bush in valve rod upper end, valve rod 3
It is threadedly coupled with thread bush 11, because thread bush 11 is fixed, and the rotation of valve rod 3 is able to achieve moving up and down for valve rod 3,
10 lower end of connecting rod is fixedly connected on valve deck 2.
Since valve rod 3 moves up and water flowing, water can permeate from the gap between valve rod 3 and upper cover, thus valve deck 2 with
Filler 12 is equipped between 3 junction of valve rod, filler 12 has leakproofness, and filler 12 is equipped with follower 13, and 13 sets of follower exists
On valve rod 3,13 side of follower is connect with valve deck 2 by movable bolt 14, and 14 one end of movable bolt is spindle rotationally arranged in valve
On lid 2, the other end passes through follower 13 and connect with nut, and this rotatable 14 connection type of movable bolt makes follower 13
It is more quick detachable between valve deck 2.
As illustrated in figures 4-5, handwheel 6 includes inner ring 61 and outer ring 62, is equipped with screw hole 18 at 61 center of inner ring, handwheel 6 it is interior
Be equipped with several between circle 61 and outer ring 62 and hold hole 15, in order to make worker put in hold hole 15 and hold handwheel 6 and work when,
It can reduce by the damage of 6 opponent of handwheel, improve comfort, the hole 15 of holding of handwheel 6 is arranged to bowl-shape, four angles for holding hole 15 are arc
Angle 20, finger are bonded with the arc angle 20 for holding 15 inside of hole, can reduce edge injury caused by finger pressure, hold the side in hole 15
Edge has protection muscle 19, and there are two starting point 21, two starting points 21 are located on outer ring 62 the protection tool of muscle 19, and the two of protection muscle 19
There is certain spacing between a starting point 21, when finger gripping is in one's hands in hole 15, protection 19 two, muscle is fitted on the inside of finger and is risen
In the spacing at beginning 21, and finger two sides are attached on two starting points 21 of protection muscle 19, and such finger can be reduced when firmly
The pressure of handwheel 6 can also improve comfort.
Worker's hand when tightening valve is non-slip in order to prevent, and connection inner ring 61 and outer ring are equipped between hole 15 in each hold
62 rib 16 is equipped on the outside of the corresponding outer ring 62 of rib 16 and holds ball 17.
In order to keep worker's work more labor-saving, inner ring 61 is amesiality relative to outer ring 62, because of the inner ring 61 of handwheel 6 and outer
Circle 62 is equipped with difference in height, it is possible to reduce the power that worker applies.
18 edge of screw hole on inner ring 61 has screw hole protrusion 22, and such worker will protrude surface cover on valve, to handwheel
It is rotated, the contact surface of screw hole 18 and valve increases, so the power that worker is applied can be smaller, worker can more be saved
Power.
