Wherein, the connecting piece be connected of upper segment valve body and hypomere valve body has following dual mode: one, through the bolt group link between upper segment valve body and the hypomere valve body, two, through the slide wedge group link between upper segment valve body and the hypomere valve body. Two kind above connection structure are convenient for dismantle last valve body and lower valve body. This novel two segmentation blast furnace gas diffuse valve when overhauing, only need pull down the sealed pad of its upper segment alright change wearing and tearing, therefore easy operation, and hoist and mount are convenient.
Description
Technical field
This utility model relates to a kind of two-part blast furnace gas discharge valve.
Background technology
Diffusion valve is the key equipment of blast furnace raw gas diffusion system, is arranged on coal gas tedge top section.It is main
Function is: when blast furnace staying, and diffusion valve is opened, and diffuses furnace pressure.It addition, blast furnace and installations and facilities are also acted as by diffusion valve
The effect of safeguard protection, when furnace top pressure exceedes setting pressure, diffusion valve automatically turns on.The work under bad environment of diffusion valve,
Containing a large amount of particulate dusts in the coal gas diffused, these particulate matter dusts can produce abrasion to valve body sealing surface, may wear to one
After determining degree, the sealing effectiveness of diffusion valve will not reach design requirement, is at this moment accomplished by overhauling diffusion valve.The most right
During diffusion valve maintenance, it is necessary to pull down the whole valve body that diffuses, then installed by diffusion valve spare part, former valve body returns factory's maintenance.This
The subject matter of mode is as follows: the volume weight of whole valve body is relatively big, and blast furnace roof narrow space and be in the height of tens meters
In the air, dismount operating difficulties, and also need to the spare part diffusion valve of same volume weight is transported blast furnace roof, then by former
Diffusion valve is transported on ground, and lifting inconvenience, expense is more expensive.
Utility model content
Problem to be solved in the utility model is to provide a kind of two-part blast furnace gas discharge valve, when maintenance, only needs
Pulling down the sealing gasket of the most replaceable abrasion of its epimere, the most simple to operate, lifting is convenient.
This utility model two-part blast furnace gas discharge valve, it includes valve gap, epimere valve body, hypomere valve body, epimere valve body
It is connected by connector under between hypomere valve body, and is provided with sealing gasket between the two.
Further, the connector that epimere valve body is connected with hypomere valve body has a following two mode: one, epimere valve body and under
Connected by bolt group between section valve body；Two, connected by wedge group between epimere valve body and hypomere valve body.Both the above connects
Structure is all easy to dismantle upper valve body and lower valve body.
Further, wedge group includes main wedge, secondary wedge, locking nut；Main wedge is from the hole of upper and lower valve body
In pass, and its hook-type face is pressed on the end face of hypomere valve body, and secondary wedge is arranged in the hole of upper and lower valve body, its lozenges
Being in close contact with the lozenges of main wedge, locking nut is spun on the screw thread on main wedge top, and is pressed on epimere valve body
On.
Further, positioned by alignment pin or articulation bolt between epimere valve body and hypomere valve body.
Further, alignment pin or articulation bolt are two, and along the circumferential direction uniform in 180 °.
So, when installing whole diffusion valve, hypomere valve body can be connected with top gas tedge.Work as diffusion valve
Sealing gasket need change time, as long as being come loose by the connector between epimere valve body and hypomere valve body, take off epimere valve body, so that it may
So that sealing gasket is changed.Owing to the volume weight of epimere valve body is less, so dismounting is got up more convenient, operate the simplest
Single.

Fig. 2 is the front view of the valve body of this utility model preferred version one；
Fig. 3 is the front view of the valve body of this utility model preferred version two；
Fig. 4 is the top view of Fig. 1.
Detailed description of the invention
The utility model is described in more detail below in conjunction with the accompanying drawings:
Embodiment 1
From fig. 1, it can be seen that this utility model two-part blast furnace gas discharge valve, it includes valve gap 3, epimere valve body 1, hypomere valve
Body 2, between epimere valve body 1 with hypomere valve body 2 under be connected by connector, and be provided with sealing gasket 4 between the two.
Embodiment 2
As can be seen from Figure 2, in above-described embodiment, described connector be bolt group 5, i.e. epimere valve body 1 and hypomere valve body 2 it
Between connected by bolt group 5.The connected mode of bolt group 5, makes between epimere valve body 1 and hypomere valve body 2 readily accessible, decreases
Workload.So, when needs change sealing gasket 4 time, as long as the bolt in bolt group is pulled down, just can by epimere valve body 1 under
Take off on section valve body 2, very convenient.
Embodiment 3
As can be seen from Figure 3, as a kind of optimal way that this is novel, in embodiment 1, described connector is wedge group 7,
I.e. connected by wedge group 7 between epimere valve body 1 and hypomere valve body 2.
Embodiment 4
In embodiment 3, described wedge group includes main wedge 71, secondary wedge 72, locking nut 73；Main wedge
71 pass from the hole of upper and lower valve body, and its hook-type face is pressed on the end face of hypomere valve body 2, and secondary wedge 72 is arranged on up and down
In the hole of valve body, its lozenges is in close contact with the lozenges of main wedge 71, and locking nut 73 is spun on main wedge 71 top
Screw thread on, and be pressed on epimere valve body 1.Wherein, the hook-type face of main wedge 71 makes the connection between upper-lower section valve body
More reliable.So, when sealing gasket 4 changed by needs, unscrew locking nut 73, main wedge 71 and secondary wedge 72 taken off,
Just epimere valve body 1 can be taken off from hypomere valve body 2, very convenient.
Embodiment 5
As can be seen from Figure 4, positioned by alignment pin between epimere valve body 1 and hypomere valve body 2.As a kind of improved procedure, on
Can also be positioned by articulation bolt 8 between section valve body 1 and hypomere valve body 2.These two kinds of structures ensure that upper and lower section of valve seal
Time centering.
Embodiment 6
On the basis of above-described embodiment, alignment pin or articulation bolt are two, and along the circumferential direction uniform in 180 °.Fixed
Position pin or articulation bolt symmetrical, may further ensure that centering during upper and lower section of valve seal.
From the above it can be seen that when the sealing gasket of this Novel diffusion valve damages, it is only necessary to demounting bolt group or tiltedly
Wedge group, just can take off epimere valve body, thus be replaced sealing gasket.
Above, preferred embodiment the most of the present utility model, but protection domain of the present utility model is not limited thereto, and appoints
What those familiar with the art in the technical scope that this utility model discloses, the change that can readily occur in or replace
Change, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with claim
The protection domain defined is as the criterion.
