Abstract
The utility model relates to a novel ball valve peeping device which comprises a lower base plate, an upper cover plate and a ball valve peeping hole body, wherein the lower base plate is welded with a furnace body in a sealed manner; the lower base plate is connected with the upper cover plate through pin shafts; a sealing plate is arranged in a space between the lower base plate and the upper cover plate; the outer part of the upper cover plate is welded with the ball valve peeping hole body; a peeping hole is formed in the center in the ball valve peeping hole body; a valve body handle is arranged on the outer wall surface of the ball valve peeping hole body. The novel ball valve peeping device has the beneficial effects that the processing is simpler; the ball valve is a general piece and is more convenient to maintain; from the structure, a small hole is used for daily observation, and in an emergency, a large hole is adopted; therefore, the heat loss in the furnace can be greatly reduced; the lower base plate and the furnace body are welded with each other in a sealed manner and then are matched with the sealing plate, so that the integrated sealing is guaranteed; during the use, an operator does not need to bend down; in an abnormal situation that a workpiece in the furnace is locked, measures such as material hooking can be executed without stopping the furnace; the influence on the atmosphere in the furnace is small.
Description
Technical field
The utility model relates to a kind of operation of blast furnace observing device, relates in particular to a kind of ball valve peeping device.
Background technology
In blast furnace production run process, directly observe for production status in the stove there being one, need to be provided with in each air port a cover peeping device.Purpose is to provide foundation for adjusting blast furnace operating, and then the direct motion of assurance blast furnace and stable, because existing spying out on the view apparatus needs the frequent assembly of changing, job step is many, uses duration, and it is large that high pressure gas produce noise, produces noise pollution.Thereby, if be applied in the cup of cementing furnace and constant-temperature oven, rear access door, discharging soft push rod top and stove inside turn place, bending part such as two sections stoves, its Main Function should possess two so, the one, in normal productive process, whether normally can observe in the stove workpiece running condition and thermal treatment situation; The 2nd, the abnormal conditions such as turn over chuck appears or in workpiece in the stove, can carry out from peep hole the emergency measures such as hook material; Simultaneously, in needs are observed stove during the workpiece situation, or when running in the stove abnormal conditions such as workpiece chuck, also to guarantee to be convenient to observe and need not blowing out.Therefore, for above aspect, need to reasonably improve prior art.
The utility model content
For above defective, the utility model provides a kind of be convenient to observe, process simple, be easy to safeguard, stopping property is better, can carry out from peep hole the ball valve peeping device of the emergency measures such as hook material, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of ball valve peeping device, comprise that lower shoe, upper cover plate and ball valve spy on hole body, lower shoe and furnace sealing welding, between lower shoe and upper cover plate, be connected by bearing pin, gap between described lower shoe and the upper cover plate is provided with sealing plate, the outside connection of described upper cover plate ball valve is spied on hole body and is spied on hole body inside center position at ball valve and offer a peep hole, is positioned on the external wall of ball valve peep hole the valve body handle is housed.
Described lower shoe top arranges four rotatable bolts and compresses, and described ball valve peep hole body side surface is installed an eyeglass.
The beneficial effect of ball valve peeping device described in the utility model is:
(1) this device is mainly used in the cup of cementing furnace and constant-temperature oven, rear access door, discharging soft push rod top and stove inside turn place, can be in normal productive process, whether normally observe the interior workpiece running condition of stove and thermal treatment situation, the abnormal conditions such as turn over chuck appears or in workpiece in stove, can carry out from peep hole the emergency measures such as hook material;
(2) comparing the more simple and ball valve of conventional cast peeping device processing is general part, keep in repair more convenient in the future, structurally use as daily observation and adopt aperture, when processing, adopts emergency macropore, can greatly reduce like this thermosteresis in the stove, lower shoe and furnace sealing welding fitted seal plate can be guaranteed integral sealing;
(3) according to human engineering, device is whole to be 5 ° of angles with body of heater, and operator need not to squat down during use, during routine work, the ball valve peeping device is closing condition, in needs are observed stove during the workpiece situation, only need rotarily open ball valve, peep hole glass adopts thermal glass; As when running in the stove abnormal conditions such as workpiece chuck, open four push bolts, with upper cover plate and ball valve integral-rotation, need not blowing out can carry out the measures such as hook material, little on the furnace atmosphere impact.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described ball valve peeping device of the utility model embodiment.
Among the figure:
1, lower shoe; 2, upper cover plate; 3, ball valve is spied on hole body; 41, outside wall surface; 42, horizontal edge; 5, sealing plate; 6, bearing pin; 7, rotatable bolt; 8, peep hole; 9, valve body handle; 10, eyeglass.
Embodiment
As shown in Figure 1, the described ball valve peeping device of the utility model embodiment, comprise lower shoe 1, upper cover plate 2 and ball valve are spied on hole body 3, lower shoe 1 wherein and furnace sealing welding, between lower shoe 1 and upper cover plate 2, be connected by bearing pin 6 and be positioned at and be pressed into four rotatable bolts 7 above lower shoe 1 and the upper cover plate 2 and compress, gap between described lower shoe 1 and the upper cover plate 2 is provided with sealing plate 5 to guarantee integral sealing, described upper cover plate 2 outside weldings ball valves are spied on hole body 3 and are spied on hole body 3 inside center positions at ball valve and offer a peep hole 8, being positioned at ball valve spies on and on hole body 3 outside wall surface valve body handle 9 is housed and this handle is connected with inner spool, simultaneously, spy on hole body 3 sides at ball valve an eyeglass 10 is installed.In addition, described ball valve is spied on hole body 3 outside wall surface 41 and is 85 ° of angles with body of heater horizontal edge 42, can guarantee that ball valve is spied on hole body 3 and body of heater is 5 ° of angles, operator need not to squat down during use, during routine work, the ball valve peeping device is closing condition, in needs are observed stove during the workpiece situation, only need rotarily open ball valve, peep hole glass adopts thermal glass; As when running in the stove abnormal conditions such as workpiece chuck, open four push bolts, with upper cover plate and ball valve integral-rotation, need not blowing out can carry out the measures such as hook material, little on the furnace atmosphere impact.
Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
