Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve equipment, in particular to an anti-deformation device for a valve plate. Background Art

[0002] The butterfly valve realizes the opening and closing functions by rotating the valve plate around the valve shaft. It mainly plays the role of cutting off and throttling in the pipeline. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, etc. High-temperature butterfly valves are mainly used in high-temperature environments and are widely used in metallurgy, building materials, chemicals, power stations, glass and other industries to meet the needs of fluid control in different occasions.

[0003] An improved high-temperature resistant and crack-resistant butterfly valve with patent application number 202221466475.6 has a good thermal insulation effect by setting thermal insulation coating and thermal insulation filler, thereby increasing the service life of the butterfly valve. However, when in use, the thermal insulation filler can only block the heat, and the efficiency of heat dissipation through the vents is limited. Heat is easily accumulated inside the valve body, causing the components to age and be damaged due to overheating, resulting in the butterfly valve being unable to work normally.

[0004] Some existing butterfly valves fix the valve plate through the valve stem. When the fluid speed is fast and the valve plate needs to be closed, a large impact force continuously impacts the valve plate, which can easily cause the valve plate to deform, affect stability and sealing effects, and easily cause damage, increasing maintenance costs.

[0005] Therefore, it is necessary to provide a new anti-deformation device for the valve plate to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of the anti-deformation device of the valve plate provided by the utility model; Figure 2 for Figure 1 The structural schematic diagram of the new cooling component shown; Figure 3 for Figure 1 A schematic diagram of the structure of the new stable component shown; Figure 4 for Figure 1 A structural schematic diagram of a novel placement groove and a support box is shown. A valve plate anti-deformation device comprises a valve body 1, the bottom of the valve body 1 is connected to a shaft seat 2, and the top of the valve body 1 is connected to a flange sleeve 3;

[0024] In the specific implementation process, Figure 1 and Figure 2As shown, the cooling component 4 is arranged on the inner side of the valve body 1, and the cooling component 4 includes a valve stem 41, a fixed block 42, a valve plate body 43, a stuffing box 44 and a guide tube 45. The inner side of the valve body 1 is rotatably connected with the valve stem 41, the outer side of the valve stem 41 is provided with a fixed block 42, one side of the fixed block 42 is fixedly connected with the valve plate body 43, the interior of the valve plate body 43 is provided with a stuffing box 44, and the interior of the stuffing box 44 is provided with a guide tube 45.

[0025] One end of the flow guide tube 45 is connected to a liquid storage box 6 , the interior of the liquid storage box 6 is connected to a connecting tube 7 , and the bottom of the liquid storage box 6 is fixedly connected to the outer side of the valve body 1 .

[0026] One end of the connecting pipe 7 is connected to a water pump 8 , and a water outlet of the water pump 8 is connected to the interior of the flow guide pipe 45 .

[0027] A through hole 9 is formed inside the valve stem 41 , a second worm gear 10 is disposed at one end of the valve stem 41 , and a sealing ring 13 is disposed on the outer side of the valve plate body 43 .

[0028] The outer side of the second worm gear 10 is meshingly connected with the first worm 11 , and one end of the first worm 11 is fixedly connected with a hand-cranked wheel 12 .

[0029] It should be noted that: the valve stem 41 is positioned on the valve plate body 43 through the two fixing blocks 42. After the guide tube 45 is connected with the water outlet of the water pump 8, it passes through the flange sleeve 3 and the valve stem 41 through the through hole 9, enters the stuffing box 44 through the valve plate body 43, and is evenly distributed inside the stuffing box 44. After passing through the stuffing box 44 and the valve plate body 43, it is supported by the inside of the valve stem 41, and passes through the valve stem 41 and the flange sleeve 3 through the through hole 9 to communicate with the inside of the liquid storage box 6. The guide tube 45 and the connecting pipe 7 are designed as hoses. When the valve plate body 43 rotates, it does not affect its placement and operation. Under the action of the guide tube 45, the coolant in the liquid storage box 6 is transported to the guide tube 45 through the connecting tube 7 and circulated. Under the action of the guide tube 45, the coolant flows on the inner side of the valve plate body 43, effectively cooling the interior of the valve plate body 43, effectively improving the cooling and heat dissipation efficiency, reducing the impact on the valve plate body 43 in a high temperature environment, and reducing the thermal deformation of the valve plate body 43 caused by high temperature. The hand-cranked wheel 12 is turned to make the first worm 11 drive the second worm gear 10 to rotate, and then the valve stem 41 drives the valve plate body 43 to rotate under the support of the shaft seat 2, so as to control the opening and closing of the valve plate body 43.

[0030] refer to Figure 1 , Figure 3 and Figure 4 As shown, the stabilizing assembly 5 is arranged on the inner side of the valve body 1 , and the stabilizing assembly 5 includes a control rod 51 and a stabilizing plate 52 . The inner side of the valve body 1 is rotatably connected to the control rod 51 , and the outer side of the control rod 51 is fixedly connected to the stabilizing plate 52 .

[0031] The stabilizing assembly 5 further includes a positioning block 53 and a first worm gear 54 . The positioning block 53 is fixedly connected to one side of the stabilizing plate 52 , and the first worm gear 54 is disposed at one end of the control rod 51 .

[0032] The outer side of the first worm wheel 54 is meshedly connected with the second worm 14 , one end of the second worm 14 is fixedly connected with a connecting rod 15 , and one end of the connecting rod 15 is fixedly connected with a motor 16 .

[0033] A support block 17 is fixedly connected to the outer side of the valve body 1 , and the inner side of the support block 17 is rotatably connected to one end of the second worm 14 . A placement groove 18 is provided inside the valve body 1 , and a support box 19 is provided on the top of the flange sleeve 3 .

[0034] It should be noted that: under the drive of the motor 16, the connecting rod 15 drives the second worm 14 to rotate under the support of the support block 17, and then the first worm gear 54 drives the control rod 51 to rotate inside the placement groove 18, thereby driving the stabilizing plate 52 and the positioning block 53 to flip, so that the positioning block 53 supports the valve plate body 43, improves the ability of the valve plate body 43 to resist large impact forces, reduces the deformation of the valve plate body 43 due to force, and extends the service life. The stabilizing plate 52 and the positioning block 53 are stored in the placement groove 18, and will not block the running trajectory of the valve plate body 43 when not in use, thereby enhancing practicality.

[0035] The working principle of the anti-deformation device of a valve plate provided by the utility model is as follows:

[0036] When in use, the valve plate body 43 is made of high-quality high-temperature resistant material. Driven by the water pump 8, the coolant in the liquid storage box 6 is transported to the guide tube 45 through the connecting pipe 7 and circulated. Under the action of the guide tube 45, the coolant flows inside the valve plate body 43, effectively cooling the inside of the valve plate body 43, effectively improving the cooling and heat dissipation efficiency, reducing the thermal deformation of the valve plate body 43 due to high temperature, and improving the sealing of the valve plate body 43 and the valve body 1 through the sealing ring 13, thereby ensuring the sealing and anti-leakage effect. Driven by the motor 16, the connecting rod 15 drives the second worm 14 to rotate under the support of the support block 17, so that the first worm wheel 54 drives the control rod 51 to rotate inside the placement groove 18, thereby driving the stabilizing plate 52 and the positioning block 53 to flip, so that the positioning block 53 contacts and supports the valve plate body 43, thereby improving the ability of the valve plate body 43 to resist large impact forces, reducing the deformation of the valve plate body 43 due to force, and extending the service life. The stabilizing plate 52 and the positioning block 53 are stored in the placement groove 18, and will not block the running trajectory of the valve plate body 43 when not in use, thereby enhancing practicality and flexibility.
