Fill cumbersome, cost is also very high.
Utility model content
For the utility model mainly solving the technical problems that providing a kind of heavy caliber shut-off valve, the present apparatus can solve big mouth
The problem of diameter seals, can also be greatly lowered production and maintenance cost.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of heavy caliber shut-off valve, valve
Body case, valve body inner casing, guide rod, driving mechanism, the valve body inner casing are that upper and lower hollow structure is welded on the valve shell
Interior, the one side of the valve shell offers air outlet, and upper top surface is removably equipped with upper cover plate, and the driving mechanism is solid
Fixed to be arranged on upper cover plate, the upper cover plate centre position is provided with guide rod and extends downward into the valve body inner casing, institute
The sealing plate for being provided on guide rod and being used cooperatively with valve body inner casing is stated, it is close that valve body inner casing upper end outer rim is provided with silica gel
Strip of paper used for sealing.
In one preferred embodiment of the utility model, the end activity that the guide rod is stretched into down in valve body inner casing connects
It is connected to supporting rod.
In one preferred embodiment of the utility model, the supporting rod is two and is vertically disposed on guide rod or so
Both sides are simultaneously in contact with the madial wall of valve body inner casing.
In one preferred embodiment of the utility model, the diameter of the sealing plate is greater than or equal to the valve body inner casing
Interior diameter.
In one preferred embodiment of the utility model, the driving mechanism is cylinder.
In one preferred embodiment of the utility model, the upper cover plate is fixed on institute by bolt or bolt and nut component
State top surface on valve shell.
In one preferred embodiment of the utility model, the diameter of the diameter of the air outlet and the valve body inner casing
It is equal.
The utility model has the beneficial effects that：The present apparatus has absorption and desorption two kinds of operating modes of exhaust gas, can be effective
Bigbore sealing problem is solved, cut-off, refractory seals are played the role of, it is simple in structure, effectively reduce production and maintenance
Cost, be suitble to widely promote the use of.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Other attached drawings are obtained, wherein：
Fig. 1 is a kind of front view of heavy caliber shut-off valve of the utility model；
Fig. 2 is a kind of sectional view of heavy caliber shut-off valve of the utility model.
Specific implementation mode
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
- 2 are please referred to Fig.1, the utility model embodiment includes：
A kind of heavy caliber shut-off valve of the utility model, including：Valve shell 1, valve body inner casing 2, guide rod 3, driving mechanism,
The valve body inner casing 2 is that upper and lower hollow structure is welded in the valve shell 1, and the upper top surface of the valve shell 1 is detachable
Upper cover plate 4 is installed, driving mechanism is fixed at 4 top of upper cover plate, and the middle part of upper cover plate 4 is equipped with guide rod 3 and downwards
It extends in the valve body inner casing 2, the lower end that guide rod 3 is stretched into down in valve body inner casing 2 is connected with supporting rod 6, supporting rod 6
It is arranged perpendicular to guide rod 3, and resists the madial wall on the both sides of valve body inner casing 2, play the role of positioning to guide rod 3, is oriented to
Sealing plate 7 is provided on bar 3,2 upper end outer rim of the valve body inner casing is provided with silicone sealing strip 8, when cylinder 5 pushes, sealing
Plate 7 is contacted and is compressed with silicone sealing strip 8, plays the role of sealing.
The upper cover plate 4 is fixed on top surface on valve shell 1 by bolt or bolt and nut component, facilitates peace installation and dismantling
It unloads.
When normal work, cylinder 5 when ventilation is needed to lift sealing plate 7, exhaust gas is entered by 2 lower section of valve body inner casing, by valve
The outlet 9 of 1 side of body case is discharged, and cylinder 5 when cut-off is needed to push sealing plate 7, and sealing plate 7 compresses silicone sealing strip 8,
Playing the role of cut-off, sealing, guide rod 3 plays the positioning action to sealing plate 7, and sealing plate 7 is further prevented to shift,
The diameter difference of shell and inner casing makes up the waste gas outlet to become smaller, and the diameter of air outlet 9 keeps phase with the diameter of valve body inner casing
Deng keeping inlet and outlet air quantity consistent.
In conclusion a kind of heavy caliber shut-off valve of the utility model, simple relative to butterfly valve structure, it is easy to operate, but
Good seal performance can effectively reduce the cost of production and maintenance.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is equally included in the patent within the scope of the utility model.
