Abstract
The utility model relates to a butterfly valve for flue adjusting, which comprises the spare parts such as an upper valve rod, an upper bearing, an upper bearing bracket, a padding gland bush, sealing padding, a valve body, a valve seat, a valve plate, a conical pin, a lower valve rod, a lower bracket, a lower bearing, etc. The valve body is formed by coiling and welding a heat-resistant alloy steel plate; a proper clearance is kept between the valve plate and the valve body; side plane sealing is adopted by the valve plate and the valve seat; the valve rods are processed by martensite stainless steel after thermal refining; a ball bearing with a seat and a pouring orifice is adopted for bearing; an external heat insulation supporting structure is adopted as a bearing bracket; and high temperature flexible graphite sealing padding is used. The butterfly valve for flue adjusting has the advantages of compact structure, small size, light weight, no blockage, stable and reliable motion, good heat and corrosion resistance performances, etc.
Description
Technical field
The utility model relates to a kind of butterfly valve, particularly relates to ash-laden gas pipe-line systems such as a kind of industrial melting, industrial boiler, the central air-conditioner adjusting butterfly valve of control automatically.
Background technique
Because of the flue butterfly valve generally be used for pressure lower (≤1.0MPa), air, ash-laden gas, industrial gas pipe-line systems such as the industrial melting of temperature higher (〉=400 ℃), industrial boiler, central air-conditioner regulate flow and pressure, the requirement resistance to heat is better, and not high to the valve base sealing requirement.
Existing flue butterfly valve generally adopts carbon steel casting valve body, Heavy Weight, and the manufacturing cycle is long, and resistance to heat is poor; Or adopt carbon steel steel plate welding valve body, and by the inner lining refractory lining, improving the valve resistance to heat, its major defect is that physical dimension is big, Heavy Weight, lining processing is difficulty.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provide a kind of simple in structure, manufacturing is easy, the flue that resistance to heat is good is regulated butterfly valve.
Technical solution of the present utility model is: a kind of flue is regulated butterfly valve, comprises component such as upper valve rod 1, upper bearing (metal) 2, upper bearing (metal) support 3, Gland 4, stuffing box packing 5, valve body 6, valve seat 7, valve plate 8, taper pin 9, lower valve rod 10, lower bracket 11, lower bearing 12.It is characterized in that described valve body adopts heat-resisting alloy steel steel plates such as 15CrMo, 12Cr1MoV, the volume circle is welded, and it is little to reach the valve volume preferably, in light weight, and the manufacturing cycle is short, the purpose that heat-and corrosion-resistant is good.
Described valve plate 8 adopts the side plane way of contact to seal with valve seat 7, can not produce radially jam.Leave the gap of 3～5mm between valve plate 8 and the valve body 6, thoroughly solve valve body 6 inwalls fouling is arranged, when ash is stifled, cause the jam problem between the valve body valve plate because of expanding with heat and contract with cold.
Described bearing bracket 3,4 adopts the heat insulation supporting structure of external, can just determine the bearing bracket extension according to working temperature, has avoided the axle head jam preferably.
Described valve rod 1,10 adopts 2Cr13 Martensitic Stain Less Steel material, through modified heat treatment, improves its intensity, hardness and wear resistance.Be used for the corrosion resistance operating mode of having relatively high expectations, but described valve rod 1,10 and valve plate 8 hard chromium plating handle, to improve decay resistance.
In the valve body stuffing box of described upper bearing (metal) 2 and lower bearing 12 inboards Expanded graphite stuffing box packing 5 is housed, by compressing the sealing that Gland 4 guarantees between valve rods and valve body.
Advantages such as the utility model product has compact structure, little, in light weight, the no jam of volume, action is reliable and stable, the heat-and corrosion-resistant performance is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A sectional drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described further.
Among the embodiment as shown in Figure 1, comprise component such as upper valve rod 1, upper bearing (metal) 2, upper bearing (metal) support 3, Gland 4, stuffing box packing 5, valve body 6, valve seat 7, valve plate 8, taper pin 9, lower valve rod 10, lower bracket 11, lower bearing 12.Valve body 6 adopts heat-resisting alloy steel steel plates such as 15CrMo, 12Cr1MoV, is welded with adpting flange after the welding of volume circle again, and it is little to reach the valve volume preferably, in light weight, and the manufacturing cycle is short, the purpose that heat-and corrosion-resistant is good.
Valve rod adopts 2Cr13 Martensitic Stain Less Steel material, through modified heat treatment, improves its intensity, hardness and wear resistance.Be used for the corrosion resistance operating mode of having relatively high expectations, but described valve rod and valve plate hard chromium plating handle, to improve decay resistance.
The Expanded graphite stuffing box packing 5 of ability high temperature more than 650 ℃ is housed, by compressing the sealing that Gland 4 guarantees between high temperature condition lower valve rod and valve body in the valve body stuffing box.
