Description
The utility model relates to pressure regulator, relates in particular to a kind of pipeline pressure voltage stabilizer.
Medium in the conveyance conduit of industries such as oil field, petrochemical enterprise, power plant all can produce very big impact (pulse) pressure, and its force value can reach more than the 40MPa.At present, employed pressure gauge on these enterprise's pipelines is because can not resist impact (pulse) pressure of pipe interior medium and frequent damage, the general life time of ordinarily manometer only 20 to 25 days.In order to reduce manometric consume, for many years, industries such as oil field, petrochemical enterprise, power plant generally adopt the mode of reload buffer device on pipeline, come impact (pulse) pressure of buffering pipe interior media, but effect are very undesirable.Its reason is: 1, buffer can only be alleviated impact (pulse) pressure of pipeline interior media, and impact (pulse) pressure of medium can not be become steady pressure output.2, behind reload buffer device on the pipeline, gauge hand still can swing back and forth, can't reading, and cause metering inaccurate.
The purpose of this utility model is to provide a kind of pipeline pressure voltage stabilizer, it installs spring, tapered piston, oil resisting rubber jointing, look nut in the columniform main body of hollow type, can be by the principle of piston damping, impact (pulse) pressure of pipe interior medium is become pressure output stably, reduce manometric loss, prolong its working life, it is big because of fed sheet of a media in the pipeline impacts (pulse) pressure to solve pressure gauge simultaneously, cause that the pointer flickered, the problem of read untrue.
The purpose of this utility model is realized by following technological scheme.
The utility model pipeline pressure voltage stabilizer, comprise the voltage stabilizer main body, seal washer, the transition packing ring, upper spring, lower spring, piston and look nut, described main body is a hollow type cylindrical body, the outer wall of this cylindrical body bottom is integrally formed with a hexahedron, the cylindrical body outer wall of hexahedron below is provided with the screw thread that is spirally connected with pipeline, the cylindrical body hollow wall offers circular hole from top to bottom successively, [shape groove, L shaped groove and have the cone tank of boss, the circular-hole internal-wall that is positioned at cylindrical body hollow wall top is provided with the screw thread that is spirally connected with pressure gauge, [the shape groove is positioned at the circular hole below, should [place seal washer in the shape groove, [shape groove below offers L shaped groove, place transition packing ring and upper spring in this L shaped groove, the transition packing ring is arranged on the top of upper spring, cone tank with boss is arranged on cylindrical body hollow wall bottom and is positioned at the below of L shaped groove, be provided with piston in this cone tank, the piston outer cover is set spring, the boss of lower spring one end and cone tank offsets, the piston bottom is provided with look nut, and cylindrical body hollow wall bottom is provided with the screw thread that is spirally connected with look nut.
Above-mentioned purpose of the present utility model can also further realize by following technical measures.
The described piston of the utility model pipeline pressure voltage stabilizer is a tapered piston; Described look nut upper and lower surface is respectively equipped with the strip groove of symmetry; Described seal washer, transition packing ring are the oil resisting rubber jointing circle.
Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Fig. 1 is the utility model overall structure schematic representation.
Fig. 2 is the utility model decomposition texture schematic representation.
Consult Fig. 1, shown in Figure 2, the utility model pipeline pressure voltage stabilizer, it comprises voltage stabilizer main body 1, seal washer 2, transition packing ring 3, upper spring 4, lower spring 5, piston 6 and look nut 7, described voltage stabilizer main body 1 is a hollow type cylindrical body, the outer wall of this cylindrical body bottom is integrally formed with a hexahedron 15, the cylindrical body outer wall of these hexahedron 15 belows is provided with the screw thread 16 that is spirally connected with pipeline, the cylindrical body hollow wall is offered circular hole 11 from top to bottom successively, [shape groove 12, L shaped groove 13 and have the cone tank 14 of boss 141, the circular-hole internal-wall that is positioned at cylindrical body hollow wall top is provided with the screw thread 111 that is spirally connected with pressure gauge, [shape groove 12 is positioned at circular hole 11 belows, should [place seal washer 2 in the shape groove, [shape groove 12 belows offer L shaped groove 13, place transition packing ring 3 and upper spring 4 in this L shaped groove 13, transition packing ring 3 is arranged on the top of upper spring 4, cone tank 14 with boss 141 is arranged on cylindrical body hollow wall bottom and is positioned at the below of L shaped groove 13, tapered piston 6 is set in the cone tank 14, piston 6 outer cover are provided with lower spring 5, the boss 141 of these lower spring 5 one ends and cone tank 14 offsets, piston 6 bottoms are provided with look nut 7, cylindrical body hollow wall bottom is provided with the screw thread 17 that is spirally connected with look nut 7, this piston 6 is a tapered piston, these look nut 7 upper and lower surfaces are respectively equipped with the strip groove 71 of symmetry, seal washer 2, transition packing ring 3 is the oil resisting rubber jointing circle.
One end and the pipeline of the utility model pipeline pressure voltage stabilizer 1 are spirally connected, and the other end and pressure gauge are spirally connected, and pull the hexahedron 15 that pressure voltage stabilizer cylindrical body outer wall is provided with hand then, the position of levelling pressure gauge and pressure voltage stabilizer 1.During use,, adjust the gap of tapered piston 6 and pressure voltage stabilizer main body 1 inwall,, make the stable indication of gauge hand actual pressure value to guarantee the pressure gauge smooth running by regulating the look nut 7 of voltage stabilizer bottom.When the media flow in the pipeline produces impact (pulse) pressure, according to piston damping function principle, medium is by look nut 7 jacking tapered pistons 6, and the strip groove 71 that is provided with by look nut 7 upper and lower surfaces, rise along lower spring 5 spirals from the both sides of tapered piston 6, enter pressure voltage stabilizer 1 top through intermediate gaps, and then after promoting upper spring 4, transition packing ring 3 top tight sealing packing rings 2, medium enters pressure gauge reposefully from the intermediate hole of seal washer 2, make gauge hand steadily be raised to specified position, guaranteed the accuracy of metering reading.
