Description
Technical field
The present invention relates to mining delivery pipe equipment technical field, specially a kind of new type mining helical bellows.
Background technique
Pipeline is that the underground of the mine constructions such as coal mine supplies water, draining, presses wind, slip casting, the transmission channel for infusing nitrogen, is coal mine
The important component of engineering system, these usual pipelines are all to lay and be fixed in wall side by side, in exploitation of mineral resources
It will be related to the installation of pipeline daily in the process, remove operation;Bellows refers to foldable wrinkle piece along folding retractable direction
The tubular elastomeric sensing element connected into, bellows are widely used in instrument and meter, are mainly used for as pressure-measuring device
The measuring cell of table converts pressure into displacement or power, and ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of pas
To tens of megapascal.Its open end is fixed, and sealed end is in free state, and increases bullet using the helical spring of auxiliary or reed
Property.It is extended under the action of internal pressure along tube length direction when work, makes movable end generation and pressure at certain relationship
Displacement, movable end drive pointer that can directly indicate the size of pressure, and bellows usually combines with displacement sensor composition
Output is the pressure sensor of electricity, is also sometimes used as isolation element, since the stretching, extension of bellows requires biggish volume to change,
Therefore its response speed is lower than Bourdon tube, and bellows is suitable for measurement low pressure, and bellows is one of pipes for mining, pipes for mining,
It is the pipeline of coal mine.Including coal mine supplying drainage, coal mine gas drainage pipe, underground coal mine shotcrete pipe, coalmine ventilation pipe, coal seam
Feed channel, coal mine connection hose etc..There are many kinds of pipes for mining, such as mining pvc pipe, mining PE pipe, mining polymer tube, it is mining not
Become rusty steel pipe, mining plastics coated tube etc..
Existing pipe used in mine is often pounded by coal seam and rock, is touched, is pressed due to its special use environment, this
Requirement to pipeline valve gasket seal is high, and the interface of such pipeline and connection ring is pounded by coal seam and rock, touches, pressed
When, the case where pipeline and connection ring are easy to happen cracking or fracture, it be easy to cause leakage, and gasket seal tear resistance
Bad, then cut is easy to extend, so that gasket seal is exposed, influences the service life of pipeline.
Summary of the invention
The purpose of the present invention is to provide a kind of new type mining helical bellows, to solve the pipeline proposed in background technique
When being pounded by coal seam and rock with the interface of connection ring, touch, press, pipeline is easy to happen the feelings of cracking or fracture with connection ring
Condition, the problem of be easy to causeing leakage.
To achieve the above object, the invention provides the following technical scheme: a kind of new type mining helical bellows, including ripple
Pipe main body, the bellows body outer wall offers several bellows main body reinforcing strips, and bellows main body one end is connected with
The first connector of bellows, and bellows main body other end is connected with the second connector of bellows, the bellows first
Connector and the nearly bellows bulk end of the second connector of bellows offer the bellows main body fixing groove of annular, and bellows
First connector and bellows the second connector outer wall offer several bellows main body welding grooves, the bellows first
Connector outer wall is equipped with several the first connector fixed blocks, and bellows the second connector outer wall is equipped with several the second companies
Fixed block installation through-hole is offered on fitting fixed block, the first connector fixed block and the second connector fixed block.
Preferably, first connector of bellows and the second connector of bellows are annular, and bellows first connects
Part and the second connector of bellows are symmetrical about the center line of bellows main body, and the first connector of bellows and ripple
The second connector of pipe uses 304K2 stainless steel material.
Preferably, the section of the first connector fixed block and the second connector fixed block is " u "-shaped.
Preferably, the bellows main body uses stainless steel material, and bellows main material model 304K2.
Preferably, there are three the bellows main body reinforcing strip is set altogether, and bellows main body reinforcing strip is uniform in the shape of a spiral
It is distributed in bellows main body.
Preferably, the interior loop-shaped kissing of the outer loop-shaped of second connector of bellows and the first connector of bellows
It closes.
