Description
Technical field
Chemical machinery field is the utility model is related to, in particular it relates to which conduit assembly, further relates to the curved of the conduit assembly
Head, and the chemical plant installations with the conduit assembly.
Background technology
In the chemical plant installations run (such as petrochemical plant), because transformation process requirement is, it is necessary in work
Increase medicament inlet on skill pipeline.Because the medium of process pipe conveying is inflammable and explosive oil gas, therefore increase medicament note
The program of entrance is typically：Device is first stopped work, and then thoroughly purges the combustible medium in clean process pipe, then process pipe
Perforate welding medicament inlet is carried out, last process pipeline carries out Welding Testing and pressure test.
But this method has the disadvantage that：Process pipe purging expends time and manpower, increases disposal of pollutants, and construction is completed
After to test and test at the scene, waste time and energy, increase device downtime.
Another solution is that the valve on process pipe is dismantled, and on both sides, flange sets up companion flange and elbow
(i.e. former flange-newly-increased companion flange-elbow-introduction pipe-former valve-introduction pipe-elbow-newly-increased companion flange-former method
It is blue), then valve is installed on the pipeline of extraction again.But this scheme has the defects of installation length is inadequate, i.e., one
Two flanges and elbow are not enough installed in the length of individual valve.

Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by
The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality
The limitation of type.
Present invention design and invention difficult point simultaneously do not lie in the brand-new conduit assembly with medicament inlet of setting.
Present invention is conceived and invention difficult point is：Less transformation is carried out to existing conduit assembly, i.e., by existing pipe
The limitation of the structure of road component, it becomes possible in the increase setting medicament inlet on existing conduit assembly.
Below with reference to the accompanying drawings conduit assembly 10 according to the utility model embodiment is described.As Figure 1-Figure 5, according to this
The conduit assembly 10 of utility model embodiment includes the first pipeline 111, second pipe 112, first flange 121, second flange
122nd, two the first elbows 130, the 3rd pipeline 140a, the 4th pipeline 140b and valve 150.
First flange 121 is connected with the first end of the first pipeline 111, second flange 122 and the first end of second pipe 112
It is connected.The first end face 131 of each first elbow 130 is configured to flange face, and each first elbow 130 has runner 132, runner
132 the first opening 1321 is opened in the first end face 131 of the first elbow 130, and the second opening 1322 of runner 132 is opened in
On the side face 133 of first elbow 130.The first end face 131 of one the first elbow 130 is connected with first flange 121, and another
The first end face 131 of one elbow 130 is connected with second flange 122.In other words, first elbow 130 and the phase of first flange 121
Even, another first elbow 130 is connected with second flange 122.
3rd pipeline 140a first end is connected with the second opening 1322 of first elbow 130, the 4th pipeline 140b
The second opening 1322 of first end and another the first elbow 130 be connected.Wherein, the 3rd pipeline 140a and the 4th pipeline 140b
In at least one be provided with medicament inlet.The import of valve 150 and one in the 3rd pipeline 140a and the 4th pipeline 140b
The second individual end is connected, outlet and another the second end phase in the 3rd pipeline 140a and the 4th pipeline 140b of valve 150
Even.
Existing conduit assembly includes the first pipeline 111, second pipe 112, first flange 121, second flange 122 and valve
Door 150, the both ends of valve 150 are provided with flange, two flanges of valve 150 respectively with first flange 121 and the phase of second flange 122
Even.
When in increase setting medicament inlet on existing conduit assembly, existing conduit assembly can be changed
Make, to obtain the conduit assembly 10 according to the utility model embodiment.Specifically, can be by valve 150 from first flange
121 and second flange 122 on disassemble, then make the first end face 131 (flange face) of first elbow 130 and the first method
Orchid 121 is connected and the first end face 131 (flange face) of another the first elbow 130 is connected with second flange 122.Then, will
3rd pipeline 140a be connected on the side face 133 of first elbow 130 and by the 4th pipeline 140b be connected to another first
On the side face 133 of elbow 130, to make the 3rd pipeline 140a be connected with the runner 132 of first elbow 130 and to make the 4th
Pipeline 140b connects with the runner 132 of another the first elbow 130.Finally, manage the pipeline 140a of valve 150 and the 3rd and the 4th
Road 140b is connected.
Thus, material can flow successively through the first pipeline 111, first flange 121, the first elbows 130, the 3rd pipelines
140a, valve 150, the 4th pipeline 140b, another first elbow 130, second flange 122 and second pipe 112.In addition, thing
The flow direction of material can also be opposite with above-mentioned flow direction.
Existing elbow is totally different from according to the first elbow 130 of the conduit assembly 10 of the utility model embodiment.Tool
For body, the first elbow 130 has flange face, i.e., the first end face 131 of the first elbow 130 is flange face, and existing elbow
All do not have flange face.Therefore, the first elbow 130 can also be considered as the flange with nonlinear runner.Existing method
Blue runner is all linear, i.e., the runner of existing flange is all axially extending along its.That is, the first elbow 130 collects
Into the function of elbow and flange.Thus two the first elbows 130 are equivalent to existing two elbows and two valves, and two
Total installation length of first elbow 130 is less than the length of the valve of identical nominal diameter, so as in the length of a valve
Two the first elbows 130 of interior installation.
According to the conduit assembly 10 of the utility model embodiment by setting and first flange 121 and the phase of second flange 122
Two the first elbows 130 even, i.e., two the first elbows 130 are set in former valvular opening position, drawn so as to set
The 3rd pipeline 140a and the 4th pipeline 140b, to install valve 150 and in the 3rd pipeline 140a and the 4th pipeline 140b
It is at least one it is upper setting medicament inlet.
Thus during increase sets medicament inlet, not only without in original pipeline (the first pipeline 111 and the
Two pipelines 112) on be open and welded operation, and without be purged to original pipeline and replacement operator.In addition, medicine
Manufacture, inspection, the experiment of agent inlet can be carried out in job shop, so as to reduce the time of device shut-down, to save
About cost, increase economic benefit.
Therefore, had according to the conduit assembly 10 of the utility model embodiment be easy to transformation, improvement cost is low, downtime
The advantages that short, without being open and being welded operation on original pipeline, without original pipeline is purged and replaced
Operation.
