[0027] The utility model provides a kind of industrial high-temperature wear-resistant regulating louvre valve, as shown in Figures 1 to 5 Including valve body 1, several drive rods 2 being rotationally arranged on the valve body 1 along horizontal direction and valve plate 3 being arranged on the drive rod 2, the valve plate 3 is sequentially staggered from top to bottom, the valve plate 3 includes upper blade 3a and lower blade 3b, the bottom of the lower blade 3b is movably attached to the top of adjacent upper blade 3a, the top of the upper blade 3a is provided with long strip-shaped connecting groove 4 along horizontal direction, the bottom of the lower blade 3b is provided with elastic connecting block 5 that can be matched with adjacent connecting groove 4, the valve body 1 is provided with driving mechanism 6 for driving the synchronous rotation of the drive rod 2.

[0028] Further, the longitudinal section of the upper blade 3a and the lower blade 3b is a right triangle.

[0029] Further, the side of the upper blade 3a close to the adjacent lower blade 3b is a first connecting part, the side of the lower blade 3b close to the adjacent upper blade 3a is a second connecting part, the first elastic connecting layer 7 is arranged on the first connecting part, and the second elastic connecting layer 8 is arranged on the second connecting part.

[0030] Further, the driving mechanism 6 includes adjusting screw rod 6a vertically arranged on the top of the valve body 1 and adjusting block 6b matched arranged on the adjusting screw rod 6a, the side of the adjusting block 6b is vertically provided with adjusting rack 9, the end of the drive rod 2 is provided with adjusting gear 10 engaged with the adjusting rack 9, and the valve body 1 is provided with adjusting motor 11 for driving the adjusting screw rod 6a.

[0031] Further, the side of the valve body 1 is provided with first limiting block 12, when the adjusting block 6b abuts against the first limiting block 12, the bottom of the lower blade 3b is attached to the top of adjacent upper blade 3a.

[0032] Further, the side of the valve body 1 is provided with second limiting block 13, when the adjusting block 6b abuts against the second limiting block 13, the upper blade 3a and the lower blade 3b are in horizontal direction.

[0033] Further, the third limiting block 14 is vertically arranged on the valve body 1, the side of the third limiting block 14 close to the adjusting rack 9 is vertically provided with long strip-shaped limiting groove 15, and the side of the adjusting rack 9 is vertically provided with long strip-shaped fourth limiting block 16 matched with the limiting groove 15.

[0034] Further, the top of the valve body 1 is vertically provided with upper baffle 17 movably attached to the top of adjacent upper blade 3a.

[0035] Further, the bottom of the valve body 1 is vertically provided with a lower baffle 18 which is movably attached to the bottom of the adjacent lower blade 3b.

[0036] Further, the upper baffle 17 and the lower baffle 18 are both made of elastic material resistant to high temperature.

[0037] When the louver valve needs to be adjusted, the adjusting motor 11 is turned on to drive the adjusting screw 6a to rotate, the adjusting block 6b drives the adjusting rack 9 to rise or fall, and the adjusting gear 10 and the driving rod 2 are rotated, thereby driving the valve plate 3 to rotate. When the louver valve is closed, the second elastic connecting layer 8 on the lower blade 3b in the valve body 1 is attached to the first elastic connecting layer 7 of the adjacent upper blade 3a, and the elastic connecting block 5 on the lower blade 3b is engaged with the connecting groove 4 of the adjacent upper blade 3a (it should be noted that the first elastic connecting layer 7, the second elastic connecting layer 8 and the elastic connecting block 5 are all made of elastic material resistant to high temperature, such as silicone rubber, fluorine rubber, etc.). Therefore, by arranging the upper blades 3a and the lower blades 3b in turn, the upper blades 3a can abut against the adjacent lower blades 3b, ensuring that the upper blades 3a and the adjacent lower blades 3b do not deflect when they abut against each other due to external wind force or the like, and ensuring the sealing between the valve plates 3. At the same time, through the cooperation of the elastic connecting block 5 and the connecting groove 4, the sealing between the valve plates 3 can still be ensured when the upper blades 3a and the lower blades 3b are worn, thereby achieving the purpose of improving the sealing of the louver valve.

[0038] By setting the cross section of the upper blade 3a and the lower blade 3b as a right triangle, the upper blade 3a and the lower blade 3b can abut against each other through the right angle surface, and at the same time, the inclined surface of the upper blade 3a and the lower blade 3b can guide the gas, dust and the like, so that the gas and dust can flow in one direction.

[0039] By setting the adjusting screw 6a, the adjusting block 6b and the like, when the louver valve needs to be adjusted, the adjusting motor 11 is turned on to drive the adjusting screw 6a to rotate, the adjusting block 6b drives the adjusting rack 9 to rise or fall, thereby driving the valve plate 3 to rotate, realizing the adjustment of the louver valve, which is simple in structure and convenient to operate.

[0040] By setting the first elastic connecting layer 7 and the second elastic connecting layer 8, on the one hand, the sealing between the valve plates 3 can be increased through the elastic abutment between the upper blades 3a and the lower blades 3b, and on the other hand, the wear resistance of the upper blades 3a and the lower blades 3b can be increased through the elastic abutment.

[0041] By setting the first limiting block 12 and the second limiting block 13, the movement range of the adjusting rack 9 can be limited, and the rotation range of the driving rod 2 is limited, avoiding excessive rotation of the driving rod 2 to cause deformation of the abutment between the upper blades 3a and the lower blades 3b, thereby avoiding affecting the service life of the louver valve.

[0042] By setting the third limit block 14, the fourth limit block 16 and the like, the moving direction of the adjusting rack 9 is guided, and the connection between the adjusting rack 9 and the valve body 1 is increased, and the stability of the moving process of the adjusting rack 9 is increased.

[0043] By setting the upper baffle 17 and the lower baffle 18, when the louver valve is closed, the sealing property between the valve plate 3 and the valve body 1 is increased, and then the overall sealing property of the louver valve is increased.

[0044] It should be noted that the various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be mutually referred to.
