The low-pressure pipeline corrosion hanging piece hanging device comprises a seal pressing cover as well as steel tubes arranged on the lower end of the seal pressing cover; the seal pressing cover is provided with a central hole with a thread; a spiral rod is provided with an external thread matched with an internal thread on the seal pressing cover, and passes through a central hole in the seal pressing cover; the upper end of the spiral rod is provided with a hand wheel, and the hand wheel is positioned above the seal pressing cover; the lower end of the spiral rod is provided with a probe rod; the outer surface of the probe rod is provided with an anti-corrosion layer; the lower part of the probe rod is provided with an installation groove and a bolt hole; the steel tubes are provided with a valve body; the bolt hole and the installation groove are used for fixing hanging pieces at two points, so that the hanging pieces are fixed firmly, and the rotation danger for single-point fixing is reduced; one point of the fixing of two points adopts a groove type, so that the positions of the hanging pieces are flexible to regulate; and the low-pressure pipeline corrosion hanging piece hanging device is reasonable in structure design, is inventive and novel in concept, is low in manufacturing cost, and are easily popularized and applied on a large scale.
Description
Technical field:
The utility model belongs to the corrosion monitoring apparatus field of petrochemical industry, and what be specifically related to is a kind of low pressure pipeline corrosion coupon suspender.
Background technology:
In the daily production run in oil field, often influence production run because of oil, letter shoot road inner wall corrosion or fouling, for effective inner-walls of duct prevents the burn into scale removal, interior media is to the influence of pipeline in the necessary pipeline of the understanding earlier operational process, comprise fouling thickness, the component of inner-walls of duct, thereby propose solution targetedly.Check the effect of various anti-corrosion measures in addition for convenience, need seek a kind of can be in the pipeline normal course of operation convenient, directly carry out the device of online suspension corrosion coupon, thereby detect pipeline operational process medium at any time to Corrosion of Pipeline.And most coupon test adopts the fixing mode of single-point, rotate easily, and lacing film is regulated inconvenient.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, provides a kind of two to select fixing, convenient and flexible installation, practical low pressure pipeline corrosion coupon suspender.
The purpose of this utility model realizes as follows: this low pressure pipeline corrosion coupon suspender, comprise sealing gland, and the steel pipe that is located at the sealing gland lower end, it is characterized in that: sealing gland is provided with the center pit that has internal thread, screw rod is provided with the external thread that matches with internal thread on the sealing gland, and pass the center pit on the sealing gland, the screw rod upper end is provided with handwheel, and handwheel is positioned at the sealing gland top, the screw rod lower end is provided with probe rod, the probe rod outside surface is provided with anticorrosive coat, and the probe rod bottom is provided with mounting groove and bolt hole, and steel pipe is provided with valve body.
Described sealing gland is connected with steel pipe by screw thread.
Described steel pipe bottom is provided with external thread.
Described handwheel and screw rod are integral structure, and the diameter of handwheel is greater than the diameter of the center pit of sealing gland.
The beneficial effects of the utility model are: under the situation that is not influencing the normal operation of pipeline, can the fast detecting low-pressure line detect the corrosion coupon of usefulness.In time grasp the operation of low pressure oil-gas pipeline dynamically, avoid because of the stopping production of installing, monitoring pipeline operation conditions is brought, get angry, workload such as dismounting large-sized flange, strengthened accuracy and validity that the pipeline operation detects.Bolt hole and mounting groove form at 2 to lacing film and fix, make that fixing of lacing film is more firm, reduced the fixing rotation danger of single-point, 2 have in fixing and a bit adopt the grooved design, make that the adjusting of lacing film position is more flexible, reasonable in design, novelty is skillfully constructed, cost of manufacture is low, is easy to large-scale promotion application.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this low pressure pipeline corrosion coupon suspender, comprise sealing gland 2, and the steel pipe 4 that is located at sealing gland 2 lower ends, it is characterized in that: sealing gland 2 is provided with the center pit that has internal thread, screw rod 3 is provided with the external thread that matches with internal thread on the sealing gland 2, and pass the center pit on the sealing gland 2, screw rod 3 upper ends are provided with handwheel 1, and handwheel 1 is positioned at sealing gland 2 tops, and screw rod 3 lower ends are provided with probe rod 6, and probe rod 6 outside surfaces are provided with anticorrosive coat 7, probe rod 6 bottoms are provided with mounting groove 8 and bolt hole 9, and steel pipe 4 is provided with valve body 5 described sealing glands 2 and is connected with steel pipe 4 by screw thread.Described steel pipe 4 bottoms are provided with external thread.Described handwheel 1 is an integral structure with screw rod 3, and the diameter of handwheel 1 is greater than the diameter of the center pit of sealing gland 2.Pipe adapter during use on the lower end of steel pipe 4 and the oil pipeline is by being threaded, the lower end of steel pipe 4 can with oil pipeline UNICOM, first valve body 5 is opened sealing gland 2 again, then screw rod 3 is put into steel pipe 4, rotate handwheel 1, screw rod 3 moves down, again with sealing gland 2 by screw thread with its good seal, open valve body 5, be rotated further handwheel 1, the corrosion coupon until probe rod 6 lower ends enters in the oil and gas pipes, at this moment valve body 5.When taking out corrosion coupon, opposite with install operation process.Under the situation that is not influencing the normal operation of pipeline, can the fast detecting low-pressure line detect the corrosion coupon of usefulness.In time grasp the operation of low pressure oil-gas pipeline dynamically, avoid because of the stopping production of installing, monitoring pipeline operation conditions is brought, get angry, workload such as dismounting large-sized flange, strengthened accuracy and validity that the pipeline operation detects.Bolt hole 9 and mounting groove 8 make the installation of 6 pairs of lacing films of probe rod form at 2 and fix, make lacing film more firm, reduced the fixing rotation danger of single-point, lacing film is the corrosion situation of monitoring equipment pipeline flexibly, and 2 have in fixing and a bit adopt the grooved design, make that the adjusting of lacing film position is more flexible, reasonable in design, the novelty that is skillfully constructed, cost of manufacture is low, is easy to large-scale promotion application.
