Description
Technical field
The present invention is a kind of buried pipeline pressure distributor on the ground.Relate to the pipe-line system technical field.
Background technique
Pressure measurement for buried pipeline, engineering all adopted buried pipeline guided to and buries ground processing mode or impulse pipeline after the pressure of ground again pressure spot is caused one by one above the ground, also has at the pipeline place that needs are installed instrument instrument well is set in the past, adopts the instrument mode is installed in the well.
Buried pipeline or pressure are got source point cause one by one on the ground, install carrying out instrument then, there are shortcomings such as perforate quantity is big on the pipeline, welding times is many, leakage point is many, safety reliability difference in this installation method for adjacent a plurality of pressure are got source point; Adopt the mounting type of instrument well not only to increase construction cost, also be unfavorable for daily operation and maintenance, and the patrolling and examining of personnel, manipulation strength have been increased, and the also easy ponding of instrument well, the draining difficulty, leave over inflammable gas after the instrument Maintenance and Repair easily, very dangerous, also need in well, to set up combustible gas detector.
Summary of the invention
The objective of the invention is to invent the buried pipeline that a kind ofly makes pipe-line construction more be tending towards standardization, modularization, hommization, minimizing working procedure and material, make things convenient for operation maintenance, reduce equipment investment and operating expenses pressure distributor on the ground.
The present invention can realize getting source point by a pressure after adopting pressure distributor for buried pipeline, satisfies the function that requires of a plurality of Pressure testing.This equipment adopts standard flange to connect, and is applicable to the operating mode of high pressure.Can manufacture according to the pressure of each engineering and the quantity of pressure distribution point.Both sides are furnished with relevant emptying, sewage draining valve and pressure Shuttoff Valve on the distributor, can carry out blowdown, shutoff and open treated to each independent Pressure testing instrument.
Formation of the present invention presses body 7 to form by flange 1, impulse pipe nipple 2, dividing potential drop pipe nipple 3, circular pipe end socket 4, blowdown end 5, blowdown pipe nipple 6, storage as shown in Figure 1-Figure 3.Horizontal pipe shape storage presses body 7 tops evenly to be connected with a plurality of dividing potential drop pipe nipples 3, and lower central is connected with impulse pipe nipple 2, and impulse pipe nipple 2 is connected with flange 1; It is circular pipe end socket 4 that body 7 one ends are pressed in storage, and the other end is the blowdown end 5 that is connected with blowdown pipe nipple 6.
Wherein:
It is the dividing potential drop pipe nipple 3 that can install more than 4 that the length of body 7 is pressed in storage, and the distance between each dividing potential drop pipe nipple 3 is equal to or greater than 180mm; Storage presses the length of body 7 to be not less than 700mm;
It is to wait external diameter that body 7 and impulse pipe nipple 2 are pressed in storage, and storage presses the external diameter of body 7 big more than the external diameter of dividing potential drop pipe nipple 3 and blowdown pipe nipple 6; The external diameter of storage pressure body 7 and the external diameter of dividing potential drop pipe nipple 3 and blowdown pipe nipple 6 satisfy the 20# carbon steel requirement of pressure rating Class 1500;
The outer end of dividing potential drop pipe nipple 3 and blowdown pipe nipple 6 has screw thread to be connected with ball valve with needle value respectively.
Adopt pressure distributor a plurality of pressure can be got source point and just can be dispensed to each Pressure testing instrument by place pressure, specious, welding times is few, the pressure advantage of high accuracy, and reduced buried pipeline perforate quantity, reduced the quantity of leakage point.Make pipe-line construction more be tending towards standardization, modularization, hommization, minimizing working procedure and material, make things convenient for operation maintenance, reduce equipment investment and operating expenses.
The present invention is applicable to that buried pipeline pressure gets the mounting type that source point surpasses the pressure instrument in the above zone of Liang Chu and two places.Get the source and detection has huge application space and good economic benefit for the buried pipeline pressure of long-distance transport pipes engineering, oil-gas field surface engineering, oil depot engineering.

Embodiment
Embodiment. this example be in Lanzhou-Zhengzhou-Changsha processed oil pipeline engineering pressure distributor on probation, it constitutes as shown in Figure 1-Figure 3, is made up of flange 1, impulse pipe nipple 2, dividing potential drop pipe nipple 3, circular pipe end socket 4, blowdown end 5, blowdown pipe nipple 6, storage pressure body 7.Horizontal pipe shape storage presses body 7 tops evenly to be connected with a plurality of dividing potential drop pipe nipples 3, and lower central is connected with impulse pipe nipple 2, and impulse pipe nipple 2 is connected with flange 1; It is circular pipe end socket 4 that body 7 one ends are pressed in storage, and the other end is the blowdown end 5 that is connected with blowdown pipe nipple 6.
Key dimension: it is Φ 60mm * 730 * 5.5mm that body 7 is pressed in storage; Dividing potential drop pipe nipple 3 is Φ 22.2 * 50 * 3.6mm; Blowdown pipe nipple 6 is Φ 13.5 * 30 * 2.5mm; Centre distance is 180mm between the dividing potential drop pipe nipple 3; Impulse pipe nipple 2 is Φ 60mm * 50 * 5.5mm; Flange 1 is Φ 190mm, high 103mm.
The ball valve material that the flange 1 of pressure distributor pressure end connection process pipelines is installed must be the low temperature carbon steel, and pressure rating must not be lower than Class 1500.
The ball valve material of being installed on the pressure distributor dividing potential drop pipe nipple 3 must be stainless steel, and pressure rating must not be lower than 6000PSI.Medium temperature recommends to adopt the sealed material of PTFE as valve seat during for normal temperature, recommends to adopt metal seat valve when using under the long term high temperature situation.Ball valve and pressure distributor connecting end are of a size of 1/2, and " NPT (F) is with the Pressure testing instrument Conncetion cimension " NPT (F) that is 1/2.Ball valve handle length is must not influence each other to good between adjacent two valves when satisfying unlatching or closed condition.
