Abstract
The utility model relates to a cone seal stop valve for liquid caustic soda controlling the medium flow in liquid caustic soda producing pipelines for chemical enterprises. The utility model comprises a valve cover assembly, a valve body, a valve clack, a middle flange gasket, a hand wheel, a stuffing pressing sleeve, and a pressing plate. The utility model is characterized in that the flat face of an inner cavity at the middle part of the valve body is provided with a cone sealing face. The surface of the cone sealing face is overlaid with corrosion resistant alloy, and the stuffing pressing sleeve adopts spherical joint with the pressing plate. The automatic seal positioning is ensured, and the flow resistance loss can be reduced at the same time. Because the sealing face is overlaid with the corrosion resistant alloy, the utility model has the advantages of favorable corrosion resistance and grinding resistance property, long service life, and safety.
Description
The utility model is that a kind of chemical industry that is used for is made the liquid caustic soda conical surface seal stop valve that control media flows on the liquid caustic soda pipeline.
Relevant by retrieval patent documentation still finds no the valve identical with the utility model structure.China's chemical industry is not specialized in the liquid caustic soda stop valve at present, so be used for the common stop valve of being of liquid caustic soda pipeline, because the sealing surface of common stop valve is corrosion resistant not, easily cause interior leakage, the filler of valve is corrosion resistant not, causes outflow, housing adopts Normal Steel Casting, valve pocket is under the pressurized situation, and explosive disrumpent feelings the splitting of housing caused economic loss; Adopt conventional sealing configuration, reach not Chemical Manufacture valve seal performance demands.
The purpose of this utility model is that a kind of sealing configuration novelty, good seal performance will be provided, corrosion resistant, safe and reliable liquid caustic soda conical surface seal stop valve.
Technical characteristics of the present utility model is: liquid caustic soda comprises valve gap assembly, valve body, flap, middle flange gasket, handwheel, filler gland, pressing plate with the conical surface seal stop valve, and it is special, and he is: be processed with conical seal (contact) face on inner chamber plane, the middle part of valve body: in its surface overlaying anticorrosion alloy is arranged; The filler gland adopts sphere to connect with pressing plate; On filler gland inner chamber and outer wall, be processed with dovetail groove.
Be installed in the liquid caustic soda conical surface seal stop valve on the liquid caustic soda pipeline, when opening/shutting valve, valve rod drives the bipyramid flap and moves up and down in the valve body body cavity, and flap adopts to float with valve rod and connects, and guaranteeing does not have adhesive wear between sealing surface.When valve closing, the sealing surface surfacing has the bipyramid flap of anticorrosion alloy and body cavity built-up welding to have the sealing surface of anticorrosion alloy to be close to, and makes valve seal tight after stressed.When the complete opening valve, the O type elastic seal ring of valve gap bottom is subjected to the extruding of flap lid end face to constitute sealing, can increase or change filler under the valve working state.
The utility model has the advantages that modern design, rational in infrastructure, because valve body adopts groove to connect with the valve gap junction point and moulds cushion cover with the corrosion resistant fluorine, reach no medium and leak outside, the flap end adopts the bipyramid structure to guarantee can reduce the flow resistance loss of valve simultaneously from the motive sealing location.Owing on sealing surface, adopt anticorrosion alloy, make the valve corrosion resistant performance good, long service life, gland keeps coaxial with valve rod all the time under stressing conditions, and valve rod moves freely up and down.Elasticity O RunddichtringO in the inside and outside dovetail groove of filler gland can guarantee filler chamber's zero leakage.Can satisfy the long-term requirement of using of chemical industry liquid caustic soda pipeline.Regulation international, relative national standards that its every performance index all reach.
Below in conjunction with description of drawings the utility model embodiment: load onto Stem Mut 12 in the end of valve gap 11, fastening with screw.Load onto O RunddichtringO 6 in valve gap bottom, the filler 7 of packing in valve gap filler chamber is inlaid with the sphere shape filler gland 9 of O RunddichtringO 8 with inner chamber and outer wall, puts into filler chamber, puts into sphere shape pressing plate 10 usefulness bolts and connects with valve gap 11.On filler gland inner chamber and outer wall, be processed with dovetail groove.Valve rod 13 is sealed in the O RunddichtringO, links through filler, filler gland, pressing plate and Stem Mut 12, load onto flap lid 4, divided ring 3 in the bottom of valve rod, will adopt the screw thread welding fastening with the flap lid with the conical seal (contact) face flap 2 of cone.On inner chamber plane, middle part, be processed with place on the flange concave surface in the valve body of conical seal (contact) face in flange gasket 5, valve gap assembly that flap will be housed and valve body 1 employing bolton.Built-up welding has anticorrosion alloy on the conical seal (contact) face of body cavity.At the valve rod top handwheel 14 is housed.
Claims (2)
1, a kind of liquid caustic soda comprises valve gap assembly, valve body, flap, middle flange gasket, handwheel with the conical surface seal stop valve, filler gland, pressing plate, it is characterized in that: on inner chamber plane, the middle part of valve body, be processed with conical seal (contact) face, anticorrosion alloy arranged in its surface overlaying; The filler gland adopts sphere to connect with pressing plate.
2, according to the described liquid caustic soda of claim conical surface seal stop valve, it is characterized in that: on filler gland inner chamber and outer wall, be processed with dovetail groove.
