Abstract
The utility model relates to a special valve for chlorine controlling the medium flow in a chlorine producing pipeline for chemical enterprises, which comprises a valve cap assembly, a valve body, a valve clack, a valve seat, a middle flange gasket, and a hand wheel. The utility model is characterized in that the end part of the valve clack is conical, and the outer side of the cone is provided with a U-shaped groove. The sealing surface of the valve seat is overlaid with corrosion resistant alloy which can improve the service life. The cone at the end part of the valve clack can reduce the shock of the sealing surface, can reduce the flow resistance, and can improve the work efficiency. The valve body and the valve cap adopt groove connection, which makes the joint position tightly combined, with good tightness. The media are ensured not to overflow, so use is safe.
Description
The utility model is a kind of valve special for chlorine that control media flows on the Production in Chemical Plant chlorine pipeline that is used for.
Relevant by retrieval patent documentation still finds no the valve identical with the utility model structure.China's chemical industry does not have special-purpose for the chlorine stop valve at present, the valve that is used on the chlorine pipeline all uses common stop valve, the valve that is used on the chlorine pipeline all uses common stop valve, because sealed attachment form and structure are unreasonable, easily leak, Sealing and material be corrosion resistant not, valve gap, valve body all adopt plain cast iron, cast steel, mechanical strength relatively poor, easily cause housing explosion and fracture, can not reach the requirement that chemical industry is used continuously, cause human injury and economic loss.
The purpose of this utility model is that a kind of sealing configuration novelty will be provided, and good seal performance, corrosion resistant make safe and reliable valve special for chlorine.
Technical characteristics of the present utility model is: the chlorine special stop valve comprises valve gap assembly, valve body, flap, middle flange gasket, handwheel, it is characterized in that: the end of flap is made as taper; Be provided with the horse shoe shaped groove in the outside of cone; Built-up welding has corrosion resisting alloy on the sealing surface of valve seat.Valve gap adopts groove to connect with valve body; Compacting sintering has corrosion resistant fluoroplastic in the horse shoe shaped groove in the outside of cone; Middle flange gasket at the groove connection place of valve body and valve gap suit elastic packing.
The utility model is installed on the chlorine pipeline, manually, surge, electronic close valve, owing to be provided with cone in the end of flap, when valve opening or when closing, the sealing surface minimizing is washed away, compacting sintering has the corrosion resistant fluoroplastic in the horse shoe shaped groove of flap, when valve closing, produce resiliently deformable, constitute gap-free sealedly, the O RunddichtringO of valve gap bottom and flap lid end seal on the formation after valve is fully opened, make under the valve working state and can change filler, the bottom of valve gap is processed with a boss when connecting with valve body, constitutes groove and connects, and makes pad place closed state.Guarantee that medium does not outflow.
The utility model has the advantages that novel structure, design are tending towards rationally, because flap, valve seat employing corrosion resistant fluoroplastic and anticorrosion alloy, the erosion that long service life, the cone of flap end can reduce sealing surface reduces flow resistance loss simultaneously, increases work efficiency.Valve body adopts groove to connect with valve gap and constitutes guiding, makes valve body and the driving fit of valve gap junction point, and is entangled by middle flange gasket, guarantees that medium does not leak outside, and is safe and reliable.Guarantee the chemical pipeline requirement of operation continuously.Regulation international, relative national standards that its every technical performance index all reaches.
Newly use new embodiment below in conjunction with this practicality of description of drawings:
The end of valve body 1 is made as taper, and the outside of cone is provided with the horse shoe shaped groove, and compacting sintering has corrosion resistant fluoroplastic in the horse shoe shaped groove.At the inner chamber of valve body middle part, load onto the valve seat 2 that built-up welding on the sealing surface has anticorrosion alloy.Load onto Stem Mut 13 at valve gap 12 tops, valve gap and Stem Mut is fastening.Zero RunddichtringO 7 of packing in the groove of the bottom of valve gap is packed spring 8 in the filler chamber of valve gap middle part into, places filler 9 then, reinstalls filler gland 10, pressing plate 11, and is fastening with bolt and valve gap.Valve rod 14 was gone here and there zero RunddichtringO 7 of valve gap bottom enter filler chamber, the gland of going here and there is stubborn mutually with Stem Mut with pressing plate.Load onto flap lid 5 in the bottom of valve rod 14, split annulus 4, adopt the screw thread welding to connect fastening on flap 3 and flap lid 5.Flange seal pad 6 in placing on the middle flange concave surface of valve body 1 will have the valve gap assembly and the valve body of the flap of flap, adopt bolton to connect, and valve gap connects with valve body employing groove.At the top of valve rod handwheel 15 is housed.
