Background
At present, a valve rod structure device of a steel rolling heating furnace inlet reversing valve is as follows: the head of the cylinder rod of the air cylinder is in an external thread shape and is provided with a pin hole, the head of the valve rod is in an internal thread shape and is provided with a pin hole, the cylinder rod is connected with the valve rod through a bolt and is fixed through the pin in an inserting mode, and the rotary displacement of the threaded connection part is prevented from affecting the stroke of the valve plate.
The dust in a workshop is more, the ambient temperature of the furnace top of the heating furnace is high, and the fault of a reversing valve cylinder is frequent. The cylinder rod and the valve rod are connected by bolts, when the reversing valve cylinder is dismounted, the pin needs to be pulled out firstly, and the valve rod is fixed by the pipe wrench to prevent the valve rod from rotating with the cylinder rod. The cylinder rod and the valve rod are difficult to screw out due to long-time action and impact. During installation, whether the head of the cylinder rod is aligned with the threaded pin hole of the head of the valve rod needs to be frequently observed. This constructional device dismouting is loaded down with trivial details, and the maintenance time factory, maintenance personal's intensity of labour is big.
In conclusion, how to realize quick installation and disassembly of the valve rod of the reversing valve becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: how to realize the quick assembly and disassembly of the valve rod of the inlet reversing valve;
in order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model relates to a quick change structure of a two-position three-way reversing valve rod of a steel rolling heating furnace, which comprises: a box body; the bracket is fixed at the top of the box body; the cylinder is fixed on the bracket in an inverted manner, and a cylinder rod of the cylinder extends into the box body; a valve plate disposed in the case; one end of the valve rod is fixedly connected with the valve plate, and the other end of the valve rod is detachably connected with the cylinder rod through a clamp;
in this scheme, the box is the box of two three-way reversing valve, drives the action of jar pole through the work of cylinder, and in addition, jar pole, valve rod, the mutual fixed connection of valve plate three, and then drive the motion of valve plate for the box, because adopt the clamp connection between jar pole, the valve rod to realize the quick change of jar pole, valve rod.
In order to explain the specific structure of the clamp, a cylinder rod and a valve rod are respectively provided with a first column body and a second column body in an extending mode towards the end part, wherein the diameter of the first column body is smaller than that of the second column body; the hoop comprises a groove body for accommodating two second columns and a plane body which is locked with each other through bolts;
in this scheme, because cylinder rod, valve rod all are provided with first cylinder, second cylinder to the tip, so the tip of cylinder rod, valve rod is the step form, holds two second cylinders with the cell body of clamp, and the both ends of two second cylinders are laminated mutually, that is to say, the height of two second cylinders equals the height of cell body; the plane body of the clamp is locked through the bolt, so that the relative up-and-down displacement of the cylinder rod and the valve rod is limited, and the cylinder rod and the valve rod are quickly detached and connected.
The utility model has the beneficial effects that: the utility model relates to a quick change structure for a valve rod of a two-position three-way reversing valve of a steel rolling heating furnace, which realizes the quick change of a cylinder of the reversing valve on the basis of not influencing the functions of the original equipment, shortens the maintenance time and reduces the labor intensity of maintenance personnel.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a mating view of a cylinder rod and a valve rod;
FIG. 3 is a schematic view of the structure of the clamp;
in the figure: 1-box body, 2-bracket, 3-cylinder, 4-cylinder rod, 5-valve plate, 6-valve rod, 7-first column, 8-second column, 9-groove body and 10-plane body.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1-3, the utility model is a quick change structure of a valve rod of a two-position three-way reversing valve of a steel rolling heating furnace, comprising: a box body 1; the bracket 2 is fixed at the top of the box body 1; the cylinder 3 is fixed on the bracket 2 in an inverted manner, and a cylinder rod 4 of the cylinder extends into the box body 1; a valve plate 5 provided in the case 1; one end of the valve rod 6 is fixedly connected with the valve plate 5, and the other end of the valve rod is detachably connected with the cylinder rod 4 through a hoop;
in this scheme, the box is the box of two three-way reversing valve, drives the action of jar pole through the work of cylinder, and in addition, jar pole, valve rod, the mutual fixed connection of valve plate three, and then drive the motion of valve plate for the box, because adopt the clamp connection between jar pole, the valve rod to realize the quick change of jar pole, valve rod.
In order to explain the specific structure of the clamp, the utility model adopts the structure that the cylinder rod 4 and the valve rod 6 are respectively provided with a first cylinder 7 and a second cylinder 8 in an extending way towards the end parts, wherein the diameter of the first cylinder 7 is smaller than that of the second cylinder 8; the clamp comprises a groove body 9 for accommodating two second columns 8 and a plane body 10 locked with each other through bolts;
as shown in fig. 3, in the present solution, since the end portions of the cylinder rod and the valve rod are both provided with the first column and the second column, the end portions of the cylinder rod and the valve rod are step-shaped, the groove body of the clamp accommodates the two second columns, and two ends of the two second columns are attached to each other, that is, the height of the two second columns is equal to the height of the groove body; the plane body of the clamp is locked through the bolt, so that the relative up-and-down displacement of the cylinder rod and the valve rod is limited, and the cylinder rod and the valve rod are quickly detached and connected.
The utility model relates to a quick change structure for a valve rod of a two-position three-way reversing valve of a steel rolling heating furnace, which realizes the quick change of a cylinder of the reversing valve on the basis of not influencing the functions of the original equipment, shortens the maintenance time and reduces the labor intensity of maintenance personnel.
