Specific embodiment
With reference to the accompanying drawings of the specification, the technical solution of utility model is described further.
A kind of valve opening is without the double eccentric electric-controlled ball valves of abrasion, as shown in Figure 1, including valve body 3, valve body 3 is equipped with reduction gearbox 5,
Reduction gearbox 5 is connect by valve rod 4 with flap 1, so that flap 1 be driven to rotate, 3 export direction of valve body is equipped with valve seat insert 2, when
When valve is closed, flap 1 compresses valve seat insert 2.Plastics material can be used without the part of the double eccentric electric-controlled ball valves of abrasion in the valve opening
Matter can be an integral molding structure.The flap 1 is that valve is spherical, and as shown in Figure 7 and Figure 8,1 inner hollow of flap, bottom is set
There is supporting shaft hole 10, is set in outside support shaft 9.Valve rod 4 is equipped with two seals slot 17, is connected by sealing ring and the sealing of valve body 3
It connects, prevents dielectric leakage in valve.
As shown in Figure 5 and Figure 6,4 lower end of valve rod is equipped with rotary table 6, including the first rotary table 16, the second rotary table 18 and eccentric round platform
15, the first rotary table 16 and the second rotary table 18 are respectively arranged at valve rod bottom surface both side, valve with 14 central symmetry of valve rod longitudinal center line
When bar 4 rotates, flap 1 is driven to rotate by the first rotary table 16 and the second rotary table 18, eccentric round platform 15 is relative to valve rod axial direction
Double eccentric structures of center line 14, as shown in fig. 6, eccentric round platform 15 while the circle relative to the first rotary table 16 and the second rotary table 18
Vertical line 19 and circle center line connecting 20 are eccentric in the heart, the circle center distance center of circle perpendicular bisector 19 of eccentric round platform 15 and the distance of circle center line connecting 20
It is 0.5mm.
As shown in Figure 7 and shown in Fig. 8, round boss 7 is equipped at the top of flap 1, round boss 7 is equipped with limiting slot 8, including
The first limiting slot 13 being equipped with the first rotary table 16, the second limiting slot 11 being equipped with the second rotary table 18.First limit
Position slot 13 and the second limiting slot 11 are sector structure, and equal angle is 90 °, and with 21 central symmetry of the round boss center of circle.
The center limiting slot 12 being equipped with eccentric round platform 15 is equipped at the round boss center of circle 21, center limiting slot 12 is waist type groove,
15 height of eccentric round platform is higher than the first rotary table 16 and the second rotary table 18, and corresponding 12 depth of center limiting slot is deeper than the first limiting slot
13 and second limiting slot 11.
As shown in Fig. 2, under valve-closed state, the eccentric round platform 15 of 4 bottom of valve rod is gone out due to wobbler action to valve
Mouth direction compresses flap 1, and flap 1 is compressed valve seat insert 2 by the squeezing action of valve rod 4, due to the eccentric round platform of 4 bottom of valve rod
15 bias 0.5mm, so flap 1 has the decrement of 0.5mm to valve seat insert 2, meanwhile, the medium in valve has flap 1
Pressure, therefore the decrement of flap 1 is greater than 0.5mm, it can be ensured that valve is in tight shut-off state.
As shown in figure 3, valve rod 4 first dallies 90 ° counterclockwise when valve opening, at this point, since eccentric round platform 15 is double eccentric structures,
Flap 1 is set to rotate 90 ° in fan groove far from valve seat insert 2, the first rotary table 16 and the second rotary table 18.When valve rod 4 is further continued for
When being rotated by 90 ° counterclockwise, flap 1 is driven to rotate by the first rotary table 16 and the second rotary table 18, since flap 1 does not contact valve
Seat sealing ring 2, therefore frictional dissipation is not generated with valve seat insert 2 during flap 1 rotates, the rotation of 1 friction free of flap
Turn 90 °, completes valve opening in place, as shown in Figure 4.
When closing valve, 90 ° of the idle running clockwise of valve rod 4, flap 1 does not contact valve seat insert 2, the first rotary table 16 and the second rotary table
18 rotate 90 ° in fan groove.When valve rod 4 continues to rotate clockwise 90 °, passes through the first rotary table 16 and the second rotary table 18 drives valve
Valve 1 rotates, and flap 1 is gradually closed and compresses valve seat insert 2, only when pass valve will be in place, flap 1 and valve base sealing
Circle 2 has the friction of moment.
Valve rod 4 all rotates 180 ° when valve opening or pass valve, and first 90 ° are idle running, and latter 90 ° just drive flap 1 to rotate together, closes
Valve events and valve opening movement are reciprocal.
