Embodiment
Below in conjunction with accompanying drawing, details of the present invention is described.
A kind of sampler that can carry out to fluid in pipeline step-down, comprise I parts and II parts, described I parts comprise step-down housing 4 and sampling axle 3, the upper end of step-down housing 4 is provided with sampling spindle nut 2, described sampling axle 3 extend in step-down housing 4 and makes to sample axle 3 by handwheel 1 rotation of sampling axle 3 upper ends settings through sampling spindle nut 2 and rises or decline, the lower end of step-down housing 4 is provided with check valve body 7, in check valve body 7, be provided with non-return valve core 6, described non-return valve core 6 is provided with aperture, liquid medium in pipeline enters aperture on non-return valve core entering in step-down body behind the gap between axle by non-return valve seat and sampling.Be provided with non-return valve seat 5 in check valve body 7 upper ends, non-return valve seat is arranged in step-down housing, and described sampling axle 3 matches with non-return valve seat 5; Sampling axle 3 seals by non-return valve seat 5, makes device in opening or closed condition, and the height that the block 51 of sampling axle upper process and non-return valve seat restriction sampling axle rise and decline, because block is blocked by part on step-down housing.The lower end of step-down housing is provided with check valve body, and the non-return valve core in check valve body plays the effect of non-return sealing under the acting force of highly pressurised liquid, and the non-return valve seat on check valve body connects the effect that sampling axle plays sealing and filters.
II parts comprise sampling nut 9, step-down body 8, in described step-down body 8, be provided with step-down dish 10 and step-down seat 11, described step-down dish 10 is evenly provided with channel disc 101, between channel disc, connect by coupling shaft 104, be provided with disk gap 103 between channel disc, described channel disc is provided with through hole 102, described step-down seat 11 precision-fit are placed in after step-down dish 10, and at step-down base rear end spring supporting, described step-down body 8 afterbodys are provided with pressure-reduction joint 12; After pressure-reduction joint 12, can also be connected to by step-down seat and step-down dish, can play the effect of the dual step-down of current limliting and decompression by step-down dish and step-down seat.
I parts check valve body 7 bottoms and II parts step-down body 8 and sampling nut 9 match.Such two parts are realized detachable.
Described sampling nut 9 precession check valve bodies 7, will back down non-return valve core 6.Can split type dismounting and combination, be conducive to the maintenance overhaul of this device and antitheft.Said sampling nut 9 backs down non-return valve core 6 in can precession check valve body 7 and samples, and screws out sampling nut 9 and make I parts and II parts separately after sampling, has reduced the volume of this device, and has prevented that part is stolen.Open handwheel and make to sample axle and rise, the liquid in pressure piping enters aperture on non-return valve core and in step-down body and in step-down seat, carries out current limliting and decompression entering after the gap filtration between axle with sampling by non-return valve seat.
Described sampling axle 3 and non-return valve seat 5 clearance fit, can play the effect of filtration, prevents that excessive impurity access to plant the inside from resulting in blockage.
The upper end open of described non-return valve seat is arranged on the medium channel axle center place of step-down housing 4.In the sampling of medium channel axle center, the data of sample detection have more accuracy.
The upper strata channel disc of described step-down dish arranges lower floor's channel disc along axle center Rotate 180 degree.Carry out rectification by step-down dish, the flow velocity of the highly pressurised liquid that slows down, reaches decompression thereby reduce pressure reduction, and it is better that stream effect of easing stress is checked and regulated in the step-down that upper strata channel disc arranges lower floor's channel disc along axle center Rotate 180 degree.
Described non-return valve core 6 and check valve body 7 play the non-return sealing function that prevents that highly pressurised liquid from revealing after sampling, and described sampling axle 3 and non-return valve seat 5 also have sealing effectiveness, and this device double seal effect is very remarkable.
This device and sampler phase specific volume in the past obviously reduce, and antihypertensive effect is more obvious, after sampler sampling simultaneously, can unload and take away, and prevent stolen stolenly, and operate light safety, can alleviate operator's labour intensity.
By reference to the accompanying drawings the preferred embodiment of the present invention is described above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, makes a variety of changes.
