Description
Technical field
The utility model relates to the coal gas pressure regulator valve equipment technical field that blast furnace is used, the low noise coal gas pressure regulator valve door that particularly a kind of blast furnace is used.
Background technique
The coal gas pressure regulator valve that blast furnace is used is so that be for further processing with the decompression of the high pressure gas of blast furnace.Currently used φ 1990 blast furnace coal gas pressure reducing valves mainly are made up of three DN700 and DN350 butterfly valve, and one of them DN700 butterfly valve is to regulate butterfly valve automatically, and DN350 butterfly valve and all the other DN700 butterfly valves are motor and speed reducer transmission.When being used for wet type coal gas dust removal equipment, also have honeycomb duct.The major defect of this blast furnace coal gas pressure reducing valve is: one, can send very strong noise in running, must be equipped with very strong muffling device for this reason, the price of this muffling device is up to 1,000,000 yuans; Two, butterfly valve can produce vibration under the impact of high pressure blast furnace gas, causes the instability of equipment operation; Three, because valve body is worn and torn by the high pressure blast furnace gas, cause reduction valve group filler place to leak easily.Therefore must put into the melting pot reduction valve group equipment on structure, reduce noise, simplified structure increases the service life.
Summary of the invention
The purpose of this utility model provides a kind of operating steadily, and friction is adjusted reliably, reduces noise, alternative muffling device, the low noise coal gas pressure regulator valve that the blast furnace that increases the service life is used.
The purpose of this utility model realizes by following technical proposals:
The low noise coal gas pressure regulator valve that blast furnace of the present utility model is used, comprise valve body, the valve body support, electric transmissio mechanism, be located at the suction port on the valve body, the air outlet, it is characterized in that the suction port supporting section of described valve body by top, the clock valve body section that is connected of suction port supporting section therewith, the air outlet supporting section that is connected of clock valve body section therewith, the supporting section base section that is connected in air outlet is formed therewith, each section cavity that described each section of valve body is made up of shell and inwall and the quieter material that is filled in this cavity are formed, in described clock valve body section, be provided with the clock valve core, the clock valve valve rod that is connected of clock valve core therewith, clock valve valve rod is made the clock valve umbrella shape supporting element be slidingly connected therewith, and described electric transmissio mechanism is connected with described clock valve core by drive link.
The Zhong Kou place of described clock valve core is provided with seal ring.
Link between described each section of valve body is a flange connector.
Described drive link is tubular rod member.
Described drive link is slidingly connected with the umbrella shape supporting element that is located in the described base section.
The low-noise gas pressure-reducing valve that adopts blast furnace of the present utility model to use, described electric transmissio mechanism moves up and down described clock valve core by drive link.When the clock valve core was moved upwards up to the extreme higher position, seal ring sealed between clock valve core and clock valve body, and coal gas does not circulate.When the clock valve core was moved down into extreme lower position, gas flow reached maximum value.By slow startup electric transmissio mechanism, can open the clock valve lentamente, reduce the impact force of air-flow, therefore make the equipment smooth running.Simultaneously and since in each section cavity of valve body filling quieter material, therefore reduced the noise that air-flow caused significantly.Because the structure of the low noise coal gas pressure regulator valve used of blast furnace of the present utility model and currently used be diverse mainly by three DN700 and DN350 blast furnace coal gas pressure reducing valve that butterfly valve is formed, therefore also just fundamentally eliminated various butterfly valves intrinsic defective, equipment operation is steady, friction, adjust reliable, reduced the noise that air-flow caused significantly, be a kind ofly can reduce noise, simplified structure, increase the service life, alternative muffling device, the coal gas pressure regulator valve that the blast furnace that investment is low is used.
Description of drawings
The low noise coal gas pressure regulator valve structural representation that Fig. 1 uses for blast furnace of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, the low-noise gas pressure-reducing valve that blast furnace of the present utility model is used, comprise valve body, valve body support 8, electric transmissio mechanism 9, be located at the suction port 18 on the valve body, valve air gate 11, it is characterized in that the suction port supporting section 1 of described valve body by top, the clock valve body section 2 that is connected of suction port supporting section 1 therewith, the air outlet supporting section 6 that is connected of clock valve body section 2 therewith, the base section 7 that is connected of air outlet supporting section 6 is formed therewith, each section cavity that described each section of valve body is made up of shell 13 and inwall 14 and the quieter material 15 that is filled in this cavity are formed, in described clock valve body section 2, be provided with clock valve core 3, the clock valve valve rod 17 that is connected of clock valve core 3 therewith, clock valve valve rod 17 is made the clock valve umbrella shape supporting element 16 that is slidingly connected therewith, and described electric transmissio mechanism 9 is connected with described clock valve core 3 by drive link 5.What Fig. 1 provided is the view that the clock valve is in closed condition.
