Abstract
The utility model relates to a sampling connection device of a non-stop transmission pipeline, which belongs to the field of connection devices of the sampling pipes of samplers and main pipelines. The sampling connection device of the non-stop transmission pipeline comprises a flange-type gland and is characterized in that the gland is fixedly provided with a guide sleeve; the centerline of the gland and the guide sleeve is provided with a sampling head channel; and a sealing filler is arranged on the sampling head channel between the guide sleeve and the gland. When the sampling connection device of the non-stop transmission pipeline is used, the flange-type gland is connected with a valve flange, the other end is connected with a sampling head flange, a sampler pipe is propelled to an oil transmission main pipe, a valve is opened to connect the pipe to a main pipeline to sample when the sampler pipe is pushed to the valve. The sampling connection device of the non-stop transmission pipeline successfully installs a sampler to sample when the pipeline does not stop transmitting, avoids losses brought by the transmission stoppage of the pipeline when in installation, and has the characteristics of safety, easiness in operation, short time and the like.
Description
Technical field
The utility model provides a kind of sampling connection set of not stopping transportation pipeline, is applicable in the main line medium not under the stopping transportation situation, and the connection set field with main line is taken in the sampler sampling.
Background technique
Crude oil pipeline of Qilu Petrochemical oil refinery existing in February, 2011 (pipe internal pressure 1.6MPa) need not installed sampler under the situation of stopping transportation at pipeline and sample.Oil refinery is entrusted Shandong Qilu Petrochemical construction Co., Ltd to be with the pressure punching to pick out valve on main line and is connected with the sampler of buying.The sampler supplier proposes a problem during connection: the installation of sampler is installed when new pipeline is installed simultaneously, and present pipeline is one and is carrying the crude oil pipeline that has certain pressure.Common operational method can cause than gross leak.
How on the pipeline of stopping transportation not, sampling is taken over and inserts main line, and do not make the crude oil leakage of band 1.6MPa pressure in the pipe? this becomes one allows tripartite stubborn problem.
The model utility content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of sampling connection set that prevents the not stopping transportation pipeline revealed is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of sampling connection set of not stopping transportation pipeline, comprise the flange-type gland, it is characterized in that: gland fixedly installs guide sleeve, the center line of gland and guide sleeve is provided with the sampling head passage, on the sampling head passage between guide sleeve and the gland stuffing box packing is set.
During use, the flange-type gland is connected with valve flanges, the other end is connected with the sampling head flange.Take over sampler to oil transportation and be responsible for propelling this moment.When shifting valve onto valve open will be taken over the insertion main line and carry out sampling work.
Wherein preferred version is:
Described guide sleeve and gland are by screwed connection.Be convenient to fixing and installation.
Described gland connects guide sleeve by stablizing bolt.Increase fixed effect, improve sealing effect.
The utility model not beneficial effect that had of the sampling connection set of stopping transportation pipeline is: by fixedly installing guide sleeve at the flange-type gland, the center line of gland and guide sleeve is provided with the sampling head passage, on the sampling head passage between guide sleeve and the gland stuffing box packing is set, during use, the flange-type gland is connected with valve flanges, the other end is connected with the sampling head flange, sampler is taken over to oil transportation be responsible for propelling, when shifting valve onto valve open will be taken over the insertion main line and carry out sampling work.The utility model is not successfully installed sampler under the situation of stopping transportation at pipeline and is sampled, and has avoided because of pipeline shutdown the loss that brings being installed, and has characteristics such as safe, easy to operate, that the time is short.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, sampling head 2, sampling head flange 3, stablize that bolt 4, gland 5, screw thread 6, guide sleeve 7, valve 8, oil transportation are responsible for 9, stuffing box packing.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, flange-type gland 4 fixedly installs guide sleeve 6, and the center line of gland 4 and guide sleeve 6 is provided with sampling head 1 passage, on the sampling head passage between guide sleeve 6 and the gland 4 stuffing box packing 9 is set.
Oil transportation is responsible for 8 in the utility model, sampling head 1 and other auxiliary facilities be common prior art, its setting and use to industry technician and grasped.
Working principle and using process:
One pipe nipple, one end is welded on the main line, and the other end welding a slice flange is connected with a valve 7, and with valve closing, band pressed drilling tool to withdraw from after band pressed drilling equipment by valve boring.
During use, flange-type gland 4 is connected with valve 7 flanges, the other end is connected with sampling head flange 2.Take over sampler to oil transportation and be responsible for 8 propellings this moment.When shifting valve 7 onto valve 7 opened and main line is inserted in adapter carry out sampling work.
The Seal Design of this covering device is copied valve seal, compresses with the graphite packing and plays seal action.Consider that the bigger employing of pipe internal pressure screws screw thread and screw connects.
Claims (3)
1. the sampling connection set of stopping transportation pipeline not comprises the flange-type gland, and it is characterized in that: gland fixedly installs guide sleeve, and the center line of gland and guide sleeve is provided with the sampling head passage, on the sampling head passage between guide sleeve and the gland stuffing box packing is set.
2. the sampling connection set of not stopping transportation pipeline according to claim 1 is characterized in that: described guide sleeve and gland are by screwed connection.
