Embodiment
Below in conjunction with accompanying drawing details of the present utility model is described.
A kind of sampler that can carry out to fluid in the 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 passes sampling spindle nut 2 and step-down housing 4 and extend in the step-down housing and by handwheel 1 rotation that sampling axle 3 upper ends arrange and make sampling axle 3 rise or descend, 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, and the liquid medium in the pipeline enters aperture on the non-return valve core in entering the step-down body behind the gap between the 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 the step-down housing, and described sampling axle 3 is complementary with non-return valve seat 5; Sampling axle 3 is in device and opens or closed condition by non-return valve seat 5 sealings, and the height that the block 51 of sampling axle upper process and non-return valve seat restriction sampling axle rise and descend is because block is blocked by part on the step-down housing.The lower end of step-down housing is provided with check valve body, and the non-return valve core in the 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 the check valve body connects the effect that the sampling axle plays sealing and filters.
The II parts comprise sampling nut 9, step-down body 8, be provided with step-down dish 10 and step-down seat 11 in the described step-down body 8, described step-down dish 10 evenly is provided with channel disc 101, connect by coupling shaft 104 between the channel disc, be provided with disk gap 103 between the channel disc, described channel disc is provided with through hole 102, after described step-down seat 11 precision-fit placed step-down dish 10, at step-down base rear end spring supporting, described step-down body 8 afterbodys were provided with pressure-reduction joint 12; Can also be connected to behind the pressure-reduction joint 12 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 are complementary.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 takes a sample, and the complete rear back-out sampling nut 9 of taking a sample makes I parts and II parts separately, has reduced the volume of this device, and has prevented that part is stolen.Open handwheel the sampling axle is risen, the aperture that the liquid in the pressure piping enters on the non-return valve core after filtering by the gap between non-return valve seat and the sampling axle carries out current limliting and decompression in entering the step-down body and in the step-down seat.
Described sampling axle 3 and non-return valve seat 5 clearance fit can play the effect of filtration, prevent that excessive impurity access to plant the inside from resulting in blockage.
The upper end open of described check valve body seat is arranged on the place, medium channel axle center 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 the 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 the stream effect of easing stress is checked and regulated in the step-down that the 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 is complete, 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 in the past sampler mutually specific volume obviously reduce, and antihypertensive effect is more obvious, can unload after simultaneously sampler sampling is complete and take away, and prevent stolen stolenly, and operate light safety, can alleviate operator's labour intensity.
The above is described preferred implementation of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
