Description

Technical Field

[0001] The invention belongs to the technical field of smelting and chemical industry, and in particular relates to a multifunctional butterfly valve for preventing locking of a smelting and chemical industry flue. Background Art

[0002] The chemical industry occupies an important position in the national economy of all countries and is the basic industry and pillar industry of many countries. The development speed and scale of the chemical industry have a direct impact on various sectors of the social economy. The annual output value of chemical products in the world has exceeded 1.5 trillion US dollars. Due to the wide range of chemical industries, complex processes, and diverse products, the pollutants discharged in production are of many types, large quantities, and high toxicity. Therefore, the chemical industry is a major polluter. At the same time, chemical products may produce a large amount of toxic substances in various links such as processing, storage, use, and waste treatment, which will affect the ecological environment and endanger human health. The sustainable development of the chemical industry has important practical significance for the economic and social development of mankind. Smelting is a refining technology, which refers to the extraction of metals from ores by roasting, smelting, electrolysis, and the use of chemical agents; reducing the impurities contained in the metal or increasing a certain component in the metal to refine the required metal.

[0003] Since a large amount of high-temperature flue gas and corrosive gases are generated during the smelting process, the material will expand and contract when the valve is subjected to hot and cold temperature shocks. In particular, if the valve cage is deformed beyond a certain range, it will lock the valve core, causing the valve to fail to operate normally. The existing similar valves have a valve cover that directly presses the valve cage structure. Under high and low temperature shocks, the valve cage has no longitudinal deformation space and can only deform horizontally. The valve cage is prone to lock the valve core. For this reason, we have proposed a smelting chemical flue anti-lock multifunctional butterfly valve. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", "all around" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0035] See also Figure 1-7 As shown, the present invention is a multifunctional butterfly valve for anti-locking of a smelting and chemical flue, comprising a valve body 100, a valve pipe 101 and a sleeve 107, flange plates 102 are welded at both ends of the valve pipe 101, and a plurality of reinforcing rods 103 are welded to the outer wall of the valve pipe 101;

[0036] The driving mechanism 200 includes a mounting seat 202, a driving rod 203 and a driving assembly for controlling the rotation of the driving rod 203. The mounting seats 202 are respectively welded to both sides of the outer wall of the valve tube 101, and the driving rods 203 are respectively installed in the interior of the sleeves 107 and fixed by fixing bolts.

[0037] The driven mechanism 300 includes an indicator rod 305 and a driven assembly connected to a plurality of driving rods 203;

[0038] The buffer mechanism 400 is installed inside the valve tube 101 and includes a housing 401 , in which auxiliary components are installed.

[0039] When in use, the flange plate 102 is connected to the flue. When the device needs to be opened, the cylinder 201 is started. The cylinder 201 pushes the push rod 206 to rotate the driving rod 203 in the middle of the valve tube 101. When the driving rod 203 in the middle of the valve tube 101 rotates, the first connecting rod 301 rotates at the same time. By adjusting the connecting rod 302, the two second connecting rods 303 are pulled to move at the same time. The driving rods 203 on the upper and lower sides of the valve tube 101 rotate at the same time, the first valve plate 104 and the second valve plate 105 are opened, and the indicating rod 305 displays the opening angle on the amplitude meter 306. When the smoke passes through the valve tube 101, the valve 104 is opened. When passing through the flame retardant sheet 405, the high-temperature flue gas exchanges heat with the flame retardant sheet 405 and blocks a certain amount of high-temperature corrosive dust, preventing the first valve plate 104 and the second valve plate 105 from heating up too high, and dissipating heat through a plurality of cooling fins 106, thereby reducing the expansion deformation of the first valve plate 104 and the second valve plate 105 and preventing locking. The valve tube 101 can be disassembled, and the fixing buckle 403 can be released to replace the flame retardant sheet 405 inside the shell 401, thereby increasing the service life of the device.

The cylinder 201 is arranged on one side of the support column 204. A rotating seat 205 is installed at the output end of the cylinder 201. One side of the rotating seat 205 is movably connected to the push rod 206 through a rotating shaft. The cylinder 201 pushes the push rod 206 to rotate the driving rod 203 in the middle of the valve tube 101. When the driving rod 203 in the middle of the valve tube 101 rotates, the first connecting rod 301 rotates at the same time. By adjusting the connecting rod 302, the two second connecting rods 303 are pulled to move at the same time. The driving rods 203 on the upper and lower sides of the valve tube 101 rotate at the same time, and the first valve plate 104 and the second valve plate 105 are opened.

[0044] In order to visually observe the opening degree of the device, the driven mechanism 300 also includes an amplitude meter 306 , on which a scale of the opening amplitude of the device is displayed.

[0045] The driven assembly includes a first connecting rod 301, an adjusting connecting rod 302, a second connecting rod 303 and a screw rod 304. The first connecting rod 301 is installed on one end of the driving rod 203 in the middle of the valve tube 101. The two second connecting rods 303 are arranged on the driving rod 203 on the upper and lower sides of the valve tube 101.

[0047] The following is the working principle of the present invention:

[0048] See also Figure 1-7 As shown, the present invention is a multifunctional butterfly valve for preventing locking of a smelting and chemical flue. The method of using the butterfly valve is as follows: the flange plate 102 is connected to the flue. When the device needs to be opened, the cylinder 201 is started. The cylinder 201 pushes the push rod 206 to rotate the driving rod 203 in the middle of the valve tube 101. When the driving rod 203 in the middle of the valve tube 101 rotates, the first connecting rod 301 rotates at the same time. By adjusting the connecting rod 302, the two second connecting rods 303 are pulled to move at the same time. The driving rods 203 on the upper and lower sides of the valve tube 101 rotate at the same time, the first valve plate 104 and the second valve plate 105 are opened, and the indicating rod 305 displays the opening angle on the amplitude meter 306. When the flue gas passes through the valve tube 101 and the flame retardant sheet 405, the high-temperature flue gas exchanges heat with the flame retardant sheet 405 and blocks a certain amount of high-temperature corrosive dust at the same time, preventing the first valve plate 104 and the second valve plate 105 from heating up too high, and dissipating heat through a plurality of cooling fins 106, thereby reducing the expansion deformation of the first valve plate 104 and the second valve plate 105 and preventing locking. The valve tube 101 can be disassembled, and the fixing buckle 403 can be released to replace the flame retardant sheet 405 inside the shell 401, thereby increasing the service life of the device. The device is easy to operate and has a good use effect, and can effectively prevent the device from locking after long-term use.
