Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
It is as shown in Figure 1 a kind of hyperboloid of one sheet flow passage gate valve of the invention, including valve body 1, valve deck 3, valve rod 4 and lock
Plate 5, the runner 2 of hyperboloid of one sheet rotary body shape is provided in valve body 1, and valve deck 3 is fixed on valve body 1 by bolt assembly and pushes up
Portion, valve rod 4 pass through valve deck 3 and extend in valve body 1, and flashboard 5 is mounted on 4 bottom of valve rod, and the end flat and runner 2 of flashboard 5 are right
Anchor ring is answered to form sealing pair.
Nut 31 is provided in valve deck 3, valve rod 4 passes through nut 31 and protrudes into valve body 1, is provided on valve rod 4 and nut 31
Matched external screw thread is equipped with handwheel 6 at the top of valve rod 4, and rotation handwheel can be rotated with ovable valve stem 4, due to the effect of nut 31,
Valve rod 4 also moves up and down while rotation, drives flashboard 5 to go up and down, opening/shutting valve.
It is illustrated in figure 2 the cross-sectional view of the runner 2 of hyperboloid of one sheet rotary body shape in the present embodiment, hyperboloid of one sheet rotation
Single leaf hyperbola formula of swivel is Y2/a2-X2/b2=1 ... ... ... ... (1), wherein a is hyp half real axis
Long, a > 0, b are that hyp half imaginary axis is long, b > 0.
As shown in figure 3, as X=0, Y=a；(0.a) is hyp vertex；Referred to herein as at the minimum of flow diameter,
A is equal to the minimum flow path radius r of valve body at this time, and value is given by designing, usually 0.8 of inside nominal diameter DN times or so；X5For
At runner outer end face, runner maximum gauge is valve inside nominal diameter DN herein；Herein, X5=body length/2, Y5=DN/2=
R。
The drafting of hyperbola rotary body is very complicated, and theoretical research can be used mathematical-specifics softwares such as " geometry plates " and be drawn
It makes, the valve flowing channel curve two-dimensional graphics Software on Drawing conventional using Auto CAD software etc., can meet engineering in the present embodiment
Required precision.The plot step of valve flowing channel curve of the invention are as follows:
S1, valve body center line (X-axis) and flashboard center line (Y-axis) are drawn first；Two axis intersect at O point, and coordinate is set as O
(0,0)；
S2, the half of body length is divided into five equal portions, and is marked in X-axis: A (0,0), B (X1) C(X2, 0), D
(X3, 0), E (X4, 0), F (X5, 0)；Its correspond to equal portions it is more, curve precision is higher, can press according to actual needs valve length and
Required precision determines isodisperse；
S3, B, C, D, E, F point are crossed, does the parallel lines of Y-axis: BH, CK, DL, EM, FN upwards；
S4, minimum flow path radius r in the middle part of valve body is marked in Y-axis, i.e. intersection point G, coordinate is (0, r)；
S5, the maximum runner radius R of valve end is marked on FN, i.e. intersection point N, coordinate is (X5, Y5)=
(X5, R)；
S6, G point coordinate value (0, r) is substituted into formula (1), obtains a2=r2；
S7, by N point coordinate value (X5, Y5) formula (1) is substituted into, obtain b2=rX5 2/(R-r)；
S8, it can be obtained by formula (1):
Y2=a2(1+X2/b2)……………………………(2)；
S9, by a2=r2And b2=rX5 2/ (R-r) substitutes into formula (2), can obtain:
Y2=r2{1+X2(R-r)/r·X5 2}…………………………………(3)；
Wherein, R, r and X5It is given value；
S10, by X1、X2、X3、X4Formula (3) are substituted into respectively, acquire Y respectively1、Y2、Y3、Y4Value；
S11, on vertical line BH, CK, DL, EM, respectively mark H (X1, Y1)、K(X2, Y2)、L(X3, Y3)、M(X4, Y4)；
S12, with spline curve sequential connection G, H, K, L, M, N；Obtain single leaf hyperbola GN；
S13, mirror image list leaf hyperbola GN is distinguished along flashboard center line and valve body center line, complete Dan Yeshuan can be obtained
