A pressing equalizing ring pipe is sleeved outside the measurement pipe, and is formed by connecting at least two circular pipes through flanges. At least three pressure leading branch pipes penetrate through a part between the pressure equalizing ring pipe and the measurement pipe, and are uniformly distributed along the circumferential direction of the measurement pipe. Each pressure leading branch pipe is provided with a pollution discharge connecting pipe plug. A master pressure lead pipe and a master pollution discharge connecting pipe plug are also arranged on the pressure equalizing ring pipe. A pressure tapping valve is arranged on the master pressure leading pipe. A ball valve is arranged on each pressure leading branch pipe. An adjustment mechanism is arranged at a joint of each pressure leading branch pipe and the measurement pipe. According to the anti-blocking type pressure equalizing tapping device, multi-point pressure tapping is adopted, pressure is uniformly led out, and the device is convenient to operate, maintain and mount, stable in measurement, high in accuracy, resistant to dirt, difficult to block, simple in structure, rational in design and high in practicability.
Description
Technical field
The utility model relates to a kind of pressure obtaning device, is specifically related to a kind of block-resistant type and all presses pressure obtaning device.
Background technology
At present when dirty media such as metallurgy industry measurement coal gas; General employing Venturi tube or orifice plate are many; And ways of measure pressure all adopts corner connection pressure, flange pressure or special pressure, because big, the characteristics such as medium is dirty, easy blocking of caliber, so traditional single-point ways of measure pressure exists the characteristics that measuring accuracy is low, maintenance clean is difficult; So the design to pressure obtaning device is particularly important; Should consider to guarantee measuring accuracy on the one hand, more need prevent on the other hand influences measuring accuracy after dirty medium from stopping up pressure obtaning device, the requirement that the prior also necessary consideration easy maintenance in long operation back is cleared up or changed.
The utility model content
The purpose of the utility model is to overcome the defective of prior art, provides a kind of block-resistant type all to press pressure obtaning device, and said block-resistant type all presses pressure obtaning device to adopt the multiple spot pressure, and pressure is drawn evenly, and operation maintenance is very convenient.
For realizing above-mentioned purpose, the technical scheme of the utility model is that a kind of block-resistant type of design is all pressed pressure obtaning device, comprises measuring tube, and measuring tube is set with the grading ring pipe outward, and the grading ring pipe is formed by connecting through flange at least two arc tubes; Be through with at least three impulses between grading ring pipe and measuring tube and be in charge of, each impulse is in charge of along measuring tube and circumferentially is uniformly distributed with, and each impulse is in charge of and is furnished with the blowdown connection plug; Also be provided with total pressure guiding pipe on the grading ring pipe.
Preferably, also be provided with total blowdown connection plug on the said grading ring pipe.
Preferably, said total pressure guiding pipe is provided with pressure measuring valve.
Preferably, said impulse is in charge of and is provided with ball valve.
Preferably, the connecting portion be in charge of with measuring tube of said impulse is provided with governor motion.
Preferably, the quantity be in charge of of said impulse is four.
Preferably, the quantity of said arc tube is two.
The grading ring pipe mainly is in charge of the pressure of drawing to each impulse and is pressed at grading ring Guan Zhongjun; The grading ring pipe has adopted two or more arc tubes to be formed by connecting through flange, so be applicable to and on already installed pipeline, carry out installation and removal; The ways of measure pressure that a plurality of impulses are in charge of makes pressure more even, makes the measurement of flowmeter more reliable and stable; The easy design of blowdown connection plug to the cleaning of device, is in charge of under situation about stopping up once in a while when impulse in operational process, can open the plug on the blowdown connection plug, dredges with the fine strip shape object, impulse is in charge of is kept unimpeded; The design of ball valve and governor motion makes device in installation process, realize easily butt joint, has guaranteed that construction is simple and convenient; Governor motion is mainly when this block-resistant type being installed at the beginning all pressing pressure obtaning device, can conveniently regulate pressure port and impulse on pipeline position and the distance between being in charge of, and makes the professional technique of installation require to reduce greatly; Ball valve is mainly and makes things convenient for the keying effect, in the on-line operation process when valve closing detachable this block-resistant type all press pressure obtaning device, make device can realize online dismounting, make the practicality of device stronger.Pressure measuring valve is mainly the pressure fairlead and does the keying effect, the pressure fairlead is connected with differential pressure gauge easily or breaks off.This block-resistant type all presses pressure obtaning device installation, maintenance, cleaning to realize easily.
The advantage and the beneficial effect of the utility model are: provide a kind of block-resistant type all to press pressure obtaning device, said block-resistant type all presses pressure obtaning device to adopt the multiple spot pressure, and pressure is drawn evenly, and operation maintenance is very convenient.And this block-resistant type all presses pressure obtaning device simple in structure, reasonable in design, has good practicability.
Compare common differential pressure flowmeter, the utility model:
A. measure and stablize, precision is high
Since adopt the multiple spot mode of all pressing that differential pressure flowmeter is carried out pressure, the measuring accuracy of raising, and make pressure more even, the measurement of flowmeter is more reliable and stable;
B. dirt, difficult stifled bears dirty
Owing to adopt the multiple spot mode of all pressing that differential pressure flowmeter is carried out pressure, do not influence measurement so stop up, and device is provided with blowdown plug device for the pressure port of property once in a while, can irregularly be in charge of and carry out the dust discharge maintenance each impulse, make its anti-blocking performance better;
C. convenient for installation and maintenance
The grading ring pipe adopts two arc tube connected modes; So be applicable on already installed pipeline and install; Also can disassemble from mounted pipeline easily simultaneously; And because each interface is thread connection, make the dismounting and the process of reinstalling need not cutting and welding, greatly reduce difficulty of construction; The design of governor motion makes device in installation process, realize easily butt joint, has guaranteed that construction is simple and convenient; The design of ball valve makes device in industrial operational process, realize online dismounting, makes the practicality of device stronger, and the long-time running good stability, and maintenance workload is minimum.
