Further, the said right connecting rod pipe that passes said valve pipe is fixedly connected with valve plate with radial hole.
Further, said incinerator internal fixation has sleeve pipe, and valve rod passes in sleeve pipe.
This high-temperature flue gas modulating valve that the utility model relates to; Simple in structure, can be when valve rod receive high temperature, the thermal expansion of valve rod all can access release at the above tie point; Cause between valve rod and the sleeve pipe not and can be out of shape mobilely and stuck, guaranteed the proper functioning of modulating valve because of valve rod.

Embodiment
As shown in Figure 1, be the plan view of the utility model high-temperature flue gas modulating valve.Modulating valve comprises valve rod 3, valve plate 10 and valve pipe 8, and valve plate 10 is arranged on valve pipe 8 inside, and valve plate 10 cross sections and the 8 interior circular section placements identical and in parallel of valve pipe are provided with seal ring 9 between valve plate 10 and the valve pipe 8; Valve pipe 8 radially has two corresponding apertures, is provided with corresponding pipe with aperture around each aperture, and valve rod 3 is a column construction.Valve plate 10 is assembly parties, and is as shown in Figure 2, and every centre has the V-type groove, uses bolt 11 to be fastenedly connected, and two plane parallel connect square hole of back valve plate 10 middle formation, link to each other with right connecting rod with the e point at the d point.Valve rod 3 is connected with left connecting rod 4; Be connected with semicircle ear link on the connecting rod 4 of a left side, link and valve rod in the vertical direction have corresponding two apertures, and link adopts bolt to be connected with valve rod 3; Left side connecting rod 4 and 3 of valve rods leave relatively turnable space, shown in Fig. 3-6.Connecting rod 5 during left side connecting rod 4 is connected with all has corresponding slotted hole on left connecting rod 4 and the middle connecting rod 5 in the horizontal direction, employing bolt connection between the two; Middle connecting rod 5 is connected with the right connecting rod 6 that can realize that vertical plane rotates; Middle connecting rod 5 is provided with semicircle ear link; Link and right connecting rod 6 all have two corresponding apertures in the horizontal direction, and be as shown in Figure 7, and the two adopts bolt to connect; Middle link 5 and 6 of right links leave relatively turnable space, the direction in each hole after the connection such as Fig. 1.Temperature raises in stove, and equipment comprises whole valve expanded by heating, and the direction of expansion is unfixed.When the valve expanded by heating, the position a that left connecting rod 4 links to each other with valve rod 3, or the position c of right connecting rod 6 and middle connecting rod 5 will do a small rotation displacement because of being heated; When valve is heated when the axial direction of valve rod 3 expands, left connecting rod 4 and middle connecting rod 5 be the b bolt in the hole, will produce an axial displacement because of being heated.
As shown in Figure 1, valve rod 3 has sleeve pipe 2 at incinerator 7 internal fixation, and valve rod 3 passes in sleeve pipe 2, when valve rod 3 temperature distortion campaigns, can play the fixedly effect of valve rod 3.The pipe that right connecting rod 6 passes valve pipe 8 is fixedly connected with valve plate 10 with radial hole, and right connecting rod 6 can directly pass the square hole that valve plate 10 forms, and the other end rides on the pipe of valve pipe 8, and the rotation of right connecting rod 6 can be controlled the rotation of valve plate 10; Right connecting rod 6 also can be divided into two sections, in this figure, is divided into two sections, and one section still is called right connecting rod 6; It is fixedly connected with an end of valve plate 10; Rotation through right connecting rod 6 is the rotation of controllable valve plate 10, and another section of right connecting rod 6 is called short valve rod 12 in this figure, and short valve rod 12 is fixedly connected with valve plate 10 at the e point; Play the effect of supporting valve plate 10, rotate with valve plate 10.
The high-temperature flue gas modulating valve makes valve realize being heated after different direction expands through these uses that connects rod member, still can be in good working order.
In the described embodiment of the utility model, do not constitute restriction to the application's scope.Every within the spirit and principle of the utility model design; As long as make the valve rod segmentation valve pipe and valve plate can realize axial displacement, horizontally rotate displacement and vertical three direction micro-displacements of swing offset, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the utility model.
