Background technique
More and more use high-pressure angle type oxygen stop valve in field of aerospace and petrochemical industry, valve pressure up to 42MPa, pure oxygen operating mode.Valve requires that pressing GB16912 cryogenic refrigeration method produces oxygen and associated gas emergency decree, IGC Doc13-02-E Europe oxygen specification, CGA G-4.4 CGA oxygen specification, HG20202 degreasing engineering construction and the standard specification such as acceptance specification and JB10530 oxygen stop valve manufacture and design, valve safety requirement is very high, comprise dust-proof, antistatic and prevent adiabatic compression, acoustic resonance, the temperature caused by gas current friction raises and burning may.
The defect of existing high-pressure angle type oxygen stop valve is, the first, and because Monel material price is higher, adopt the valve body structure size of integral (type) flange connection or welded flange comparatively large, cost is higher, and make valve price higher, competitive ability is poor; The second, valve rod is dust-proof not in place, and as only at the additional protecting cover of valve rod, dust-proof, the dust-proof of gland gap for platen gap are not arranged, and therefore not talkative is that valve rod is truly dust-proof; 3rd, adopt the cylinder of conventional 0.8MPa, larger than valve 2 ~ 3 times of cylinder dimensions, make valve to install; 4th, due to perforation processing, there is wedge angle, dead angle and blind area in valve channel, brings danger to oxygen flowing; 5th, MEDIA FLOW is to low in and high out, and medium power is unfavorable for sealing.The present invention overcomes above-mentioned shortcoming completely, has the feature of Economy, Security and operability.
Summary of the invention
The object of this invention is to provide a kind of high-pressure angle type oxygen stop valve, it is applicable to the Pneumatic angle type stop valve of high pressure oxygen operating mode.
The present invention realizes like this, high-pressure angle type oxygen stop valve, it comprises the valve body with middle lumen pore, its side canal hole is communicated with middle lumen pore with vertical passage hole, the side of valve body is connected with earth stud, valve body is installed with rivet and prohibits oil ga(u)ge board, flap is provided with in valve body, flap is connected with valve clack cover, valve clack cover is connected with valve rod, the valve gap with through hole is set with outside valve rod, valve gap is provided with flange, flange is fixed on valve body by screw bolt and nut, pad is lined with between valve gap and valve body, Packing seat is provided with between valve rod and valve gap, PTFE filler and filler, valve rod is also set with pressing plate outward, pressing plate is fixed on valve gap by screw bolt and nut, valve rod between pressing plate and valve gap is set with gland, the top of valve rod is fixed with splits connecting sleeve, split connecting sleeve and be fastenedly connected valve rod and high pressure cylinder by screw bolt and nut, the outside of flange is provided with poly (methyl methacrylate) plate, the top of poly (methyl methacrylate) plate is connected with flange, poly (methyl methacrylate) plate is by bolt and flange and Flange joint, flange is by column and nut and Flange joint, flange is bolted high pressure cylinder.
Advantage of the present invention is, valve body adopts the solid forging of Monel nickel-copper alloy forging; Valve body adopts the solid forging of Monel nickel-copper alloy forging, and end flange connects to adopt processes flanged surface and tapped hole on body.Owing to have employed direct thread mill drilling, simplify the structure, saved material, reduced cost; Lumen adopts fine copper pad, and fine copper pad meets pure oxygen in high pressure operating mode, is conducive to reducing lumen size; Dust-proof, the anti-fat of valve rod and prevent impurity from entering filler along valve rod, adopts the totally-enclosed design of poly (methyl methacrylate) plate, is closed completely by the moving elements such as valve rod, and combustion explosion that valve pocket causes may effectively to prevent impurity from entering; Anti-static device is set, valve body arranges ground connection conducting bolt, issuable electrostatic is imported underground.Avoid because static-induced spark causes an explosion accident; Adopt the high pressure cylinder of 5MPa source of the gas to drive, efficiently solve high-pressure angle type pneumatic oxygen stop valve and adopt the problem that conventional pneumatics volume is too large; Connecting sleeve is split in employing, bolton, easy for installation; Realize valve rod to be connected with the reliable of cylinder; In order to ensure that valve operation is steady, close easily, MEDIA FLOW is to employing high in and low out; Valve two channel diameter is identical with valve seat orifice diameter, and runner transition is mild, does not have dead angle and blind area, is conducive to oxygen and flows safely; Valve gap is made up of the outer disk of the inner disc and connecting bolt of installing filler, and interior disk material is Monel nickel-copper alloy forging, and outer disk material is F304 stainless steel forgings, and compared with the valve gap of overall Monel nickel-copper alloy forging, cost of material significantly reduces.
