Sealant, is provided with support block on the inside of the sealant, scribble corrosion-resistant coating on the inside of the valve body, and valve body left and right two
Side is respectively arranged with liquid outlet and inlet.
Preferably, the buffer spring is symmetricly set in the gap between valve rod and connecting rod.
Preferably, the structure that the flap is integrated with stem design.
Preferably, the two sides of the flap mutually coincide with sealant.
Preferably, the height of the inlet is more than the height of liquid outlet, and both cavitys of inner side are provided with necessarily
The protective layer of thickness.
Compared with prior art, the beneficial effects of the utility model are:The corrosion resistant through type Fluorine-lined of the security seal is cut
Only valve, buffer spring and wearing layer are provided with the lower end of fixes sleeve, when flap and sealant contact with each other, buffer spring
Play certain thrust to valve rod, it is to avoid when manual rotational force is excessive, cause mutually squeezing out for flap and sealant
The problem now damaged;And the structure that flap is integrated with stem design, it is ensured that flap is not influenceed by fluid, is substantially increased
Steadiness, while flap mutually coincide with sealant being connected, the effect of sealing is good;The built-in anticorrosive coat of valve body, and liquid in-out mouthful
Inner side is all provided with matcoveredn, even if will not also be corroded by medium after a long time use, overall barrier propterty is strong, uses
Long lifespan.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1, Fig. 2 and Fig. 3 are referred to, the utility model provides a kind of technical scheme:A kind of security seal is corrosion resistant straight
Formula Fluorine-lined stop valve, including operation handwheel 1, valve rod 2, fixes sleeve 3, buffer spring 31, wearing layer 32, connecting rod 4, fixation
Bolt 5, end cover 6, sealing ring 7, flap 8, inlet 9, sealant 10, protective layer 11, liquid outlet 12, valve body 13, anti-corrosion
Erosion layer 14 and support block 15, the upper end of valve rod 2 are provided with operation handwheel 1, and intermediate position is provided with fixes sleeve 3, fixed
The lower end of sleeve 3 is fixed with wearing layer 32, and the inner side of wearing layer 32 is connected with buffer spring 31, and buffer spring 31 is symmetrical arranged
In gap between valve rod 2 and connecting rod 4, certain thrust is existed to valve rod 2, when preventing revolving force excessive, cause valve
The mutual extruding of valve 8 and sealant 10 and the problem damaged, sealing ring 7 is located between adjacent seals end cap 6, and end cover 6
Outside be provided with fixing bolt 5, the upper end of end cover 6 is connected with each other by connecting rod 4 with one end of valve rod 2, flap 8
In the bottom of valve rod 2, flap 8 designs the structure being integrated with valve rod 2, it is ensured that flap 8 is not influenceed by fluid, is substantially increased
Steadiness, two sides and the sealant 10 of flap 8 mutually coincide, and the effect sealed in the state of being brought into close contact is good, and its left and right
Both sides are fixed with sealant 10, and the inner side of sealant 10 is provided with support block 15, and the inner side of valve body 13 scribbles corrosion-resistant coating 14, and
The left and right sides of valve body 13 is respectively arranged with liquid outlet 12 and inlet 9, and the height of inlet 9 is more than the height of liquid outlet 12,
Close valve when required power it is small, open valve when required larger power, and both inner side cavity be provided with it is certain thickness
Protective layer 11, it is ensured that will not medium corrosion and damage.
The operation principle of the present embodiment:In through type Fluorine-lined stop valve corrosion resistant using the security seal, first to this
The structure of device is simply understood, when needing to close valve, rotation process handwheel 1 so that valve rod 2 moves down, together
When flap 8 and the one of valve rod 2 structure, moved down together also with valve rod 2, until the two sides of flap 8 and sealant 10
After mutual tight connecting, now the lower surface of flap 8 is also at the state of contacting with each other with support block 15, and medium enters from inlet 9
Enter in the valve pocket in valve body 13, blocked with sealant 10 by flap 8, as close valve;And buffer spring 31 is by solid
Determine sleeve 3 and certain thrust is existed to valve rod 2, when preventing revolving force excessive, cause the mutual extruding of flap 8 and sealant 10
And damage problem, built-in corrosion-resistant coating 14 prevent enter medium to its inwall cause corrosion, extend the use of the device
Life-span;The height of inlet 9 when thus closing off valve, under the thrust of medium, only needs very little more than the height of liquid outlet 12
Revolving force, it is opposite when opening valve, under the resistance of medium, it is necessary to larger power just can poppet stem 2, this should be safe
Seal the operation principle of corrosion resistant through type Fluorine-lined stop valve.
