As shown in Fig. 7 d, the middle part of boss 27 is provided with recess 22 ", recess 22 " sidewall be provided with radially convex profile 23 " and two pits 24 ", 25 ", recess 22 " diapire on be provided with microscler positioning hole 26 ".Radially the convex profile 23 " shape identical with radially convex profile 23 on the spool top, also comprise successively spacing preiection 23 " a, initial part 23 " b, intermediate portion 23 " c and termination section 23 " d.Microscler positioning hole 26 is " identical with microscler positioning hole 26 shapes on spool top.
Figure 10 illustrates the stereogram according to an embodiment of the driving component 13 of mangetic core assembly of the present utility model.As shown in Figure 8, driving component 13 has roughly U-shaped body 131, is respectively equipped with positioning hole 132 and positioning hole 133 at two arms of U-shaped body 131, and positioning hole 132,133 shape of cross section are quadrilateral.But one skilled in the art should appreciate that, positioning hole 132,133 shape of cross section also can be other polygonal shapes or irregularly shaped such as triangle, if its respectively with valve rod 4 on the shape of cross section of locating column 44 and the shape of cross section of actuator 5 " on locating column 55 " be complementary.Should point out, driving component 13 also can adopt other shape and structures, as long as it can be delivered to the rotation of valve rod actuator 5 ' and actuator 5'.
After assembling is completed, as shown in Figure 2, after valve rod 4 passes the valve rod hole 1c on valve body 1 top, then pass the splined hole 51' of actuator 5', and be inserted in the microscler positioning hole 26 of spool 2, and the locating column 46 of valve stem end inserts in the driving hole 132 of driving component 13.Sealed by O RunddichtringO 7 between the hole wall of valve rod 4 and valve body 1.Buckle slot 43 on valve rod 4 is snapped with fastener 12, and valve rod is played the spacing effect that stops, valve rod 4 can not be extracted from valve body.Spline 44 insertion actuators 5 on valve rod 4 ' in, to realize transmission.The guide rod 45 of valve rod is contained in microscler positioning hole 26, and the cooperation of microscler positioning hole 26 and valve rod guide rod 45 is mainly to the effect that (namely doing radial motion along microscler positioning hole) plays forced guiding that moves radially of spool.
Actuator 5' is placed in the recess 22 on spool 2 tops, and elasticity convex tendon 53 and 54 end snap in respectively in spacing pit 24 and 25, as shown in figure 14, and imposes on the certain elastic pressure of radially convex profile on spool 2 tops because being squeezed.
Therefore, in the situation that the rotational resistance of spool 2 is less, the combination of the end of the pit by spool 2 tops and the two elasticity convex tendons of actuator 5', and pit 24', 25' and actuator 5 by spool 2 bottoms " the combination of end of two elasticity convex tendons, actuator 5 ' " can be with simultaneously movable valve plug 2 synchronously to rotate with actuator 5.
When valve was switched to closed condition by open mode, valve rod rotated, and valve rod is lived by means of square location and the cooperation of the square opening of driving component, drove driving component driving bottom actuator.Valve is when open mode, and spool does not contact with valve seat, and the resistance that is subject to during rotation is the frictional force of the revolute pair in each link, so rotational resistance is very little, almost can ignore.What be positioned at the recess end and the spool top of the elasticity convex tendon of the actuator of the spool top being connected with the bottom be connected with the bottom this moment makes two actuator Timing Belt movable valve plugs rotations (as shown in Figure 11 a and 11b) being connected of two pits, after spool turns over roughly 90 degree, the just contact or aim at valve seat of the closed end of spool, and spool and the spacing barrier structure of valve body in the bottom make spool to rotate in the slewing areas of 90 degree in valve body.after spool turns over roughly 90 degree, increase moment of rotation on valve rod, the end of the elasticity convex tendon of the actuator on spool top and bottom and the pit of recess are thrown off (as shown in Figure 12 a and 12b), make actuator radially the evagination profile along spool radially the convex profile rotate, thereby make two ends, spool up and down synchronously move radially (acquisition moves radially component), this moment spool top and bottom the recess of actuator and spool top and bottom in microscler positioning hole coordinate moving radially of spool played the forced guiding effect, when evagination profile radially rotates termination section from the initial part of cam contour, spool applies predetermined pressure to valve seat around here, both mutually press tactile according to predetermined pressure, the conductive channel cut-off of valve, thereby valve cuts out.
when needs are opened valve, the backward rotation valve rod, the rotation of valve rod drives the actuator backward rotation by driving component, larger frictional force is arranged because the pressure of spool and valve seat is tactile, spool can be along with actuator rotates, the radially evagination profile of actuator forwards initial part to from the termination section of convex profile radially, the elasticity convex tendon provides reposition force, make between actuator and recess and reset to initial position, therefore the pressure that is applied to spool this moment disappear, synchronously separate with valve seat at two ends, spool up and down, frictional force between them also so thereupon disappears, poppet shaft is to resetting, thereby reach pre-opening state.At this moment, be provided with spacing preiection on inner circle wall due to recess, during the driving component backward rotation, radially the evagination profile just touch after spacing preiection can not be again spool backward rotation relatively, and this moment, the end of two elasticity convex tendons also was embedded in the pit of inner circle wall of recess, spacing preiection and the interaction force between the inner circle wall pit of the interaction of evagination profile and elasticity convex tendon and recess radially will make driving component band movable valve plug backward rotation 90 degree to the state that makes the valve passage conducting.
In mangetic core assembly of the present utility model and valve, due to spool close in advance or opening process in, spool does not contact with valve seat or valve body, be in the hovering state, reduce the frictional force of their contacts, the moment of torsion (only have when the moment that valve body is closed and just understand the lateral extrusion spherical valve core) that reduce to rotate, this just makes valve rod very little of moment of torsion in the process of rotation, thereby reaches the effect of low moment of torsion opening and closing valve.In addition, the sealing of valve is fine.
The valve that it should be noted that previous embodiment of the present utility model is take ball valve as example, but also can be with structure applications of the present utility model to other valves, for example butterfly valve.Each member of the present utility model also can adopt other structures and not break away from spirit of the present utility model.For example, handle and valve rod can be separate parts separately, can be also the parts of one, valve rod can adopt splined with connecting of actuator, also can adopt other connecting modes well known by persons skilled in the art such as scyewed joint, anchoring connection, welding.
One skilled in the art will understand that the utility model is embodied as other particular form, and do not break away from its spirit or inner characteristic.Above-described embodiment all will be understood as that it is only exemplary with nonrestrictive in all respects.Therefore, scope of the present utility model is limited by the specification of appending claims rather than front.All fall within change in the implication of claims equivalent and scope all will be included in the scope of claims.
