Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and implementation column:
As Fig. 1, Fig. 2, shown in Figure 3, be the utility model expanssion type high temperature flap type structural representation, described expanssion type high temperature flap type is made up of handwheel 1, Gland 2, high temperature filler 3, valve gap 4, stud 5, nut 6, valve rod 7, cylindrical nut 8, gasket ring 9, auxiliary gate-board 10, valve seat 11, main gate-board 12 and valve body 13.
Flashboard is designed to the oblique split surface form of V-arrangement, is divided into main gate-board 12 and auxiliary gate-board 10, and both are slidingly matched, and surface of contact is the oblique split surface of V-arrangement.Wherein, two positioning dowels 24 that distribute on the side of the width direction of main gate-board 12 lay respectively at upper and lower two-part of main gate-board; Be distributed with a positioning dowel 24 on the side of the width direction of auxiliary gate-board 10.By Returnning spring 23 being passed the both sides of these three positioning dowels 24 respectively, main gate-board 12 and auxiliary gate-board 10 are connected as one.One end of valve rod 7 is fixed with handwheel 1, one end and is connected with cylindrical nut 8 by valve rod lifting screw thread 15, and cylindrical nut 8 is connected with main gate-board 12 by main gate-board cylindrical hole 25.The outer side surface of main gate-board 12 and auxiliary gate-board 10 contacts with the inner side surface of valve seat 11.
Be furnished with high temperature filler 3 and Gland 2 between valve gap 4 and the valve rod 7, Gland 2 compresses the polished rod seal position of 3 pairs of valve rods 7 of high temperature filler and carries out elevated-temperature seal.Gasket ring 9 is installed between valve gap 4 and the valve body 13,, valve gap 4 is connected one with valve body 13, screw nut 6 simultaneously, make it apply the sealing pretightening force, thereby make valve gap 4 and valve body 13 form the high-temperature metal sealing gasket ring 9 by stud 5 and nut 6.
When flap type cuts out, handwheel 1 turns clockwise, because of handwheel 1 is connected with valve rod 7, valve rod 7 promotes screw thread 15 by valve rod and is connected with cylindrical nut 8, cylindrical nut 8 is connected with main gate-board 12 by main gate-board cylindrical hole 25, this moment, main gate-board 12 was subjected to the 7 end thrust effects of dextrorotation rotating valve rod, and auxiliary gate-board 10 is moved downward along valve rod 7 axial directions by major-minor flashboard ramp 17 thrust also simultaneously; When auxiliary gate-board 10 when valve rod 7 axial directions arrive valve body hole bottom 14, contact with auxiliary gate-board lower end surface 22, be subjected to the spacing effect in valve body hole bottom 14, main gate-board 12 continues to move downward along major-minor flashboard ramp 17, this moment, auxiliary gate-board 10 was made extensional motion to both sides valve seat 11 axial directions, up to fitting tightly with sealing surface of seat 21, valve seat end face Baltimore groove 18 end faces of valve seat 11 also further fit tightly with valve seat orifice end face 19 simultaneously, and valve seat both sides end face fits tightly and makes flashboard two sealing planes and sealing surface of seat 21 and valve seat and 19 applying formation metal and the metallic seals of valve seat orifice end face.
When flap type is opened, handwheel 1 is rotated counterclockwise, main gate-board 12 promotes under the screw thread 15 axial tension effects at the valve rod of valve rod 7, main gate-board 12 and auxiliary gate-board 10 are to the motion of axis top, the Returnning spring 23 that is installed in this moment on the positioning dowel 24 resets auxiliary gate-board, whole flashboard continues up stroke and is subjected to the spacing effect of valve gap 4 end faces up to auxiliary gate-board upper-end surface 16, and the flap type complete opening puts in place.Because the sealing between flashboard and valve seat and valve seat and the valve body all is the sealing of metal and metallic material, therefore, stable working is very reliable under the worst hot case, and the refractory seal performance is splendid, long service life.
