Core of the present utility model is, provides a kind of hydrophobic regulating valve special for alumina, and under limiting spool and valve seat contact condition by restriction rotating mechanism, valve seat with the rotation of spool relative to valve body, and then is stopped because valve seat rotates the incomplete problem of sealing caused.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to Fig. 2 and Fig. 3, wherein, Fig. 2 shows the structural representation of hydrophobic regulating valve special for alumina embodiment provided by the utility model, and Fig. 3 shows the close-up schematic view of Fig. 2.
As shown in Figure 2, hydrophobic regulating valve special for alumina comprises valve body 1, valve seat 2, spool 3 and driving mechanism, and wherein, valve body 1 offers medium inlet 1
inwith media outlet 1
out, the medium inlet 1 in the valve pocket that valve seat 2 is installed on valve body 1 and for being communicated with valve body 1
inwith media outlet 1
out, spool 3 turns round around the center line of valve seat 2 and linearly moves back and forth along this center line under driving mechanism effect, opens and closes with control valve seat 2.It should be noted that, under the center line of valve seat 2 refers to valve seat 2 closed condition herein, the center line of the ring packing pair that both valve seat 2 and spool 3 are formed.
Continue known see Fig. 3, driving mechanism comprises valve rod 4, Stem Mut 5 and handwheel 6, wherein, one end of valve rod 4 is fixedly connected with spool 3, the other end and Stem Mut 5 are spirally connected mutually, Stem Mut 5 has radial flange, Stem Mut 5 runs through valve body 1, one external part is offseted by radial flange and valve body 1, sheathed and the handwheel 6 that is connected of its another external part, also namely Stem Mut 5 limits it relative to the movement of valve body 1 along valve rod 4 axis by handwheel 6 and its radial flange, makes it only can do rotation motion around valve rod 4 axis.That is, valve rod 4 and Stem Mut 5 form screw nut driving mechanism, drive spool 3 around the center line revolution of valve seat 2 and linearly move back and forth along this center line, thus the keying of control valve seat 2.
It should be noted that, the axis of the valve rod 4 of above-mentioned driving mechanism with above in the centerline collineation of valve seat 2 mentioned, also namely spool 3 around valve rod 4 axis revolution and move back and forth along its axis linearity.
Be appreciated that the driving mechanism of spool 3 is not limited to said structure, the basis meeting assembly technology requirement also can adopt mechanical design field the rotation motion of an assembly can be transformed in order to the revolution of another assembly and the mechanism of linear reciprocating motion.
In addition, then composition graphs 3 is known, and above-mentioned aluminium oxide is special hydrophobicly also comprises restriction rotating mechanism, under the sealing surface contact condition of valve seat 2 and spool 3, for limiting valve seat 2 with the rotation of spool 3 relative to valve body 1.
Particularly, composition graphs 2 and Fig. 3 known, in the first embodiment, restriction rotating mechanism comprise holding down bolt 7, this holding down bolt 7 runs through valve body 1 and is spirally connected with valve body 1, its afterbody insert valve seat 2.
In this embodiment, if holding down bolt 7 and valve rod axis collinear or when be arrangeding in parallel, after spool 3 moves to and contacts with the sealing surface of valve seat 2 under driving mechanism effect, continue relative to valve seat 2 when valve rod axis rotates, under this torsional interaction, holding down bolt 7 likely rotates relative to valve body 1 until departed from by valve body 1, will cause the disabler of restriction rotating mechanism like this.
For this reason, in this embodiment, the axis of holding down bolt 7 and the gyration center of spool 3 intersect setting, to reduce spool 3 moment of torsion to the impact of holding down bolt 7, ensure the connection reliability of holding down bolt 7 and valve body 1.
Further, as shown in Figure 3, in this embodiment, the axis of holding down bolt 7 and the gyration center of spool 3 intersect (degree) in 90 ° angle, so, spool 3 moment of torsion can be avoided completely on the impact of holding down bolt 7, further increase the connection reliability of holding down bolt 7 and valve body 1.
Valve seat 2 offers multiple damping hole 21, the medium inlet 1 of valve body 1
inwith media outlet 1
outbe communicated with especially by these damping holes 21, and these damping holes 21 are all positioned at the upstream side of spool 3, the afterbody of holding down bolt 7 inserts in damping hole 21, like this without the need to processing slot or the jack of plug-in mounting holding down bolt 7 afterbody at valve seat 2, simplify processing technology, reduce the overall improvement cost of hydrophobic regulating valve special for alumina.
Because damping hole 21 is for being communicated with the medium inlet 1 of valve body 1
inwith media outlet 1
outif holding down bolt 7 takies the normal work that damping hole 21 will have influence on drain regulating valve completely, for this reason, the afterbody size relationship between the two of damping hole 21 and holding down bolt 7 is further defined in this embodiment.Particularly, the section area of damping hole 21 is greater than the radial cross section area of the afterbody of holding down bolt 7, so that the afterbody of holding down bolt 7 does not affect its infusion function while running through damping hole 21.
Further, as shown in Figure 3, damping hole 21 is strip hole, and in order to ensure that it has transfusion concurrently and prevents afterbody two kinds of functions of holding down bolt 7, the triangular proportionate relationship of tail diameter of the length of damping hole 21, width dimensions and holding down bolt 7 is preferably 2:1.1:1.
Be appreciated that on the basis meeting damping hole 21 dual functions, the triangular proportionate relationship of tail diameter of the length of damping hole 21, width dimensions and holding down bolt 7 is not limited to aforementioned proportion relation.
In another embodiment, restriction rotating mechanism comprises locating stud, and this locating stud runs through valve body 1 and is connected with valve body 1 static seal, and the afterbody of locating stud inserts in valve body 1.In this embodiment, the object that valve body 1 is connected with locating stud static seal is, prevents dielectric leakage in valve pocket.
For the object same with the first embodiment, the afterbody of locating stud inserts the damping hole 21 of valve body 1 equally, and the section area defining damping hole 21 is greater than the section area of the afterbody of locating stud.
Further, the shape of damping hole 21 and the dimension scale relation with locating stud afterbody thereof is also defined in this embodiment, damping hole 21 is strip hole, and the triangular proportionate relationship of tail diameter of the length of damping hole 21, width and locating stud is 2:1.1:1.
In addition, it should be noted that, in above-mentioned two kinds of embodiments, the quantity of holding down bolt 7 and alignment pin is not limited to one, those skilled in the art can according to actual needs and the composite factor of installing space size arrange two or more.
