Abstract
The utility model relates to a kind of hydrogenation stop valve, comprise valve body, valve rod, support, handwheel, one end of valve rod is fixedly connected with handwheel by the Stem Mut on support, support and valve rod arrange cooperatively interact torsional stop and anti-rotation groove respectively, compressed by Gland between valve body and valve rod and filler is installed, stuffing box is set between filler and Gland; Mainly valve body adopts one forging molding, and acutangulate structure between valve outlet channel centerline and valve rod center line, the other end pile-up welding hard alloy sealing surface of valve rod, stuffing box connects nipple, the other end setting pressure sensor of nipple.When filler is by when occurring after stem wear leaking, pressure transducer automatically detects and sends leakage signal, repairs leakage point in time, and avoid hydrogen medium to leak outside generation security incident, Safety performance is good.Be applicable to the block valve of hydrogenation pipeline in petroleum refining industry hydrogenation plant integrated system.
Description
Technical field
The utility model belongs to valve field, particularly about a kind of stop valve.The utility model is applicable to the block valve of hydrogenation pipeline in petroleum refining industry hydrogenation plant integrated system.
Background technique
In petroleum refining process process, generally all improve petroleum product-quality by hydrogenation.So hydrogenation plant is the important equipment of petroleum refining process, the hydrogenation pipeline of hydrogenation plant generally adopts the circulation of stop valve pilot line medium or blocks.The structure of existing stop valve is generally made up of valve body, flap, valve gap, valve rod, handwheel, arranges the sealing surface of seat cooperatively interacted with valve clack sealing surface, install packing seal between valve rod and valve gap in the passage between valve body is imported and exported.Owing to adding hydrogen medium, to have inflammable and explosive, corrosivity strong, and medium leaks outside and easily causes burning, explode and the security incident such as etching apparatus.When wearing and tearing appearance leakage occurs existing stop valve filler between valve rod and valve gap, automatically can not detect and find that leakage solves a problem promptly, safety in utilization is poor.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, provides one automatically can detect packing leaking, the hydrogenation stop valve that safety in utilization is good.
The technical solution of the utility model comprises valve body, valve rod, support, handwheel, one end of valve rod is fixedly connected with handwheel by the Stem Mut on support, support and valve rod arrange cooperatively interact torsional stop and anti-rotation groove respectively, compressed by Gland between valve body and valve rod and filler is installed, stuffing box is set between filler and Gland; Mainly valve body adopts one forging molding, and acutangulate structure between valve outlet channel centerline and valve rod center line, the other end pile-up welding hard alloy sealing surface of valve rod, stuffing box connects nipple, the other end setting pressure sensor of nipple.
The utility model has the advantages that on stuffing box by nipple setting pressure sensor, when filler is by when occurring after stem wear leaking, pressure transducer automatically detects and sends leakage signal, repairs leakage point in time, avoid hydrogen medium to leak outside generation security incident, Safety performance is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 valve body, 2 valve rods, 3 fillers, 4 nipples, 5 pressure transducers, 6 supports, 7 plane bearings, 8 Stem Muts, 9 handwheels, 10 bolts, 11 Glands, 12 stuffing boxes.
Embodiment
Hydrogenation stop valve as shown in Figure 1, comprise valve body 1, valve rod 2, support 6, handwheel 9, one end of valve rod 2 is fixedly connected with handwheel 9 by the Stem Mut 8 on support 6, mounting plane bearing 7 between Stem Mut 8 lower end surface and support 6, reduce to open and close operational torque, support 6 and valve rod 2 arrange cooperatively interact torsional stop and anti-rotation groove respectively, by the straight line motion that the convert rotational motion of handwheel 9 is valve rod 2, compressed by Gland 11 between valve body 1 and valve rod 2 and filler 3 is installed, stuffing box 12 is set between filler 3 and Gland 11, Gland 11 is arranged on valve body 1 by bolt 10, decrease the leakage point between existing stop valve valve gap and valve body, valve body 1 adopts one forging molding, structure is acutangulated between valve body 1 outlet passage center line and valve rod 2 center line, the other end pile-up welding hard alloy sealing surface of valve rod 2, this cemented carbide sealing surface forms valve clack sealing surface, and the sealing surface of seat that valve body 1 is imported and exported between passage cooperatively interacts, stuffing box connects nipple 4, the other end setting pressure sensor 5 of nipple 4, when occurring after filler 3 weares and teares by valve rod 2 to leak, pressure transducer 5 detects leakage signal automatically, and send leakage alarm signal, maintenance man is made to overhaul filler 3 in time, avoid medium to leak and cause security incident.
