Background technology
To study or measuring the chemical composition or humidity of flowing steam in heat distribution pipeline or container, normal conditions
It is lower to need to draw steam from system using a set of sampler arranged along conduit axis direction, but
Steam flow direction in pipeline or container is not necessarily perpendicular to the section of equipment, that is to say, that probe tube
Direction can not be accurately consistent with steam flow direction, and some vapor and water exist and is lost in sampling process, because
This cannot ensure the accuracy of sampling.
Traditional sampler once sample tap direction is installed because just cannot adjust, it is impossible to accomplish accurately with
The flow direction of steam is consistent, causes the actual measured results of steam moisture or composition and physical presence error.
The adjustable sampler in a set of direction is designed, accurate research or measurement flowing steam moisture or composition are weighed very much
Will.

Lower end is fixedly connected with described sampling head.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：Regulation spiral shell is connected on described piston
Nail, the adjusting screw is threadedly coupled with described cylinder body.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：Described piston includes cylinder originally
Body and piston ring, piston ring set is outside cylindrical body, and piston ring is in sealing contact with described inboard wall of cylinder block.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：Described stock is rigid thin rod,
A diameter of 2~4mm, is made of austenitic stainless steel or aluminium alloy exotic material.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：Described austenitic stainless steel is 304
Austenitic stainless steel or 316 austenitic stainless steels.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：Described aluminium alloy exotic material
It is 2A70 or 2A80.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：Described sampling head is processed for lower end
Tapered stainless steel tube.
In a kind of above-mentioned adjustable flowing steam sampling structure in direction：The cylinder block material is aluminium alloy.
Remarkable result of the invention is：Promote piston to be moved in cylinder body using adjusting screw, drive traction
Bar can swing around it with the junction of piston, and draw bar promotes sampling head to swing, therefore need not be equipped with electronic
Device, that is, realize the regulation in sampling head direction, regulation sampling head direction make its accurately with the flowing of steam
Direction is consistent, and sampling error is reduced, and solves the problems, such as that conventional vapor sampling time error is big.
2) high temperature resistant and high pressure, due to selected materials all for austenitic stainless steel (such as 304 austenitic stainless steels,
316 austenitic stainless steels) and aluminium alloy exotic material (2A70 or 2A80), and intensity is all higher,
Therefore the present apparatus with resistance to 200 DEG C~400 DEG C of high temperature and can be not less than the pressure of 10MPa.
It is safe and reliable, when piston produces relative motion with cylinder body, due to the piston ring designed on piston, its energy
Enough ensure piston and the good sealing effectiveness of cylinder body；Meanwhile, the thin pressure screw thread in adjusting screw has good
Anti- load-carrying ability, risk is smaller during operation device.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
As shown in figure 1, flexible elbow 6 is one section of curved stainless steel bellows, with ductility and bendability.
Flexible elbow 6 is located in pipeline 4, and the two ends of flexible elbow 6 are respectively mounted sampling head 8 and steam fairlead 7.
One end of flexible elbow 6 is fixed on the upper end of steam fairlead 7 by the way of welding, and the other end is welded on
The upper end of sampling head 8.Steam fairlead 7 passes through pipeline 4, is fixed on tube wall, in order that steam is from the mouth of pipe
Well into the mouth of pipe of steam fairlead 7 sweeps away.
For the sampling head 8 described in accurate adjustment, can be accurately consistent with steam flow direction, taking
Draw bar 5 is fixedly mounted on sample first 8.The upper end of draw bar 5 is installed by piston 3 and cylinder body 2.The cylinder 2 is pacified
Mounted in the outer wall of pipeline 3, piston 3 is sealingly mounted in cylinder body 2, one end of the lower end of piston 3 and draw bar 5
It is hinged, the other end of draw bar 5 is fixedly connected with sampling head 8.The promotion of above-mentioned piston 3 is by regulation
What screw 1 was realized.
Cylinder body 2 is the cylinder of inner wall smooth, and material can use aluminium alloy, the rear end of cylinder body 2 and adjusting screw 1
The part machining internal thread of contact.
Piston 3 is made up of cylindrical body and piston ring two parts, and piston ring 302 is cased with outside cylindrical body,
Piston ring 302 still has good sealing property when ensure that piston 3 with 2 relative motion of cylinder body, no
Leak steam.
Draw bar 5 is rigid thin rod, and a diameter of 2~4mm, end and the lower end of piston 3 of draw bar 5 are hinged,
To ensure that draw bar 5 can swing around it with the junction of piston 3.
Draw bar 5 using austenitic stainless steel (such as 304 austenitic stainless steels, 316 austenitic stainless steels) or
Person's aluminium alloy exotic material (2A70 or 2A80) is made, and ensure that rigidity and intensity are enough to affect
Or promote sampling head 8 to swing, and oneself does not deform.
Steam fairlead 7 is stainless steel tube, is connected with flexible elbow 6, and be welded and fixed.
Sampling head 8 is that lower end processes tapered stainless steel tube.
When using, adjusting screw 1 is rotated, affect or promote piston 3 to do straight-line displacement, piston in cylinder body 2
3 linear motion drives draw bar 5, draw bar 5 to pull or promote sampling head 8 to swing.
When sampling head 8 swings, due to the effect of flexible elbow 6, make the bottom section of sampling head 8 in pipe
The interior direction that can be towards needed for experiment in road 4, the judgement in the direction of sampling head 8 can use following methods：
The outside of pipeline 4 processes four along the circumferential uniform pressure tappings of pipeline 4, under the position of pressure tappings and sampling head 8
End sustained height, reads the pressure difference between 4 pressure tappings to judge.
Wherein, adjusting screw 1 can use turret head or square head bolt, using fine thread, the row of screw thread
Cheng Yingyou enough length can produce larger straight-line displacement to ensure linkage part.
