The present invention is achieved through the following technical solutions.
A kind of pipe sampler, comprise pipeline valve body, sampling valve body, flap, valve rod, handwheel, above-mentioned sampling valve body hollow also in a tubular form, it is through pipeline valve body vertical with the liquid medium flow direction in pipeline valve body, above-mentioned valve rod be shorter in length than above-mentioned sampling valve body, above-mentioned valve rod to stretch in above-mentioned sampling valve body and screw-thread fit with it, one end that above-mentioned valve rod is being positioned at above-mentioned sampling valve body is fixedly connected with flap, its the other end is positioned at that above-mentioned sampling cock is external is fixedly connected with handwheel, above-mentioned sampling cock body is positioned at above-mentioned pipeline valve body and the part of the sphere of activities of above-mentioned valve rod is provided with at least one through hole.
Further, above-mentioned sampling valve body is provided with gland nut in one end of the above-mentioned valve rod of turnover, and above-mentioned valve rod stretches into above-mentioned sampling valve body through above-mentioned gland nut.
Further, be provided with the filler being sleeved on above-mentioned valve rod in above-mentioned sampling valve body, above-mentioned filler is compressed by above-mentioned gland nut.
Further, above-mentioned sampling valve body is provided with sealing nut at sample tap place.
Further, above-mentioned sampling valve body is formed by two sections, be designated as the first sampling valve body subsegment, the second sampling valve body subsegment respectively, above-mentioned valve rod is positioned at above-mentioned first sampling valve body subsegment and screw-thread fit with it, and the bore of above-mentioned first sampling valve body subsegment is greater than above-mentioned second and samples valve body subsegment.
Further, above-mentioned flap is tapered and one end that is that be connected with above-mentioned valve rod is wide mouth, and external part is cone mouth, and the wide mouth bore of above-mentioned flap is greater than the bore of above-mentioned second sampling valve body subsegment.
Further, the above-mentioned pipeline valve body that is positioned at is provided with chuck, and above-mentioned chuck two ends arrange an import and an outlet respectively.
Beneficial effect of the present invention:
Eliminate and draw pipe and valve, make in sampling process, not be used in the medium stayed in emptying pipe and valve when starting to sample, avoid the waste of raw material; Directly sample in the middle of main pipeline, ensure that the validity (purity) of sample; Directly sample from main pipeline, if avoid medium have easy coking or solidify characteristic when common sampling cock can not get the situation of sample.

Embodiment
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 be inventive pipeline sample collector face cross-sectional schematic, Fig. 2 is the diagrammatic side-view cross-sectional schematic diagram of inventive pipeline sample collector, with reference to Fig. 1, Fig. 2, the present invention, pipe sampler, comprise pipeline valve body 4, sampling valve body 2, flap 5, valve rod 6, handwheel 9, sampling valve body 2 hollow also in a tubular form, it is through pipeline valve body 4 vertical with the liquid medium flow direction in pipeline valve body 4, being shorter in length than of valve rod 6 samples valve body 2, valve rod 6 to stretch in sampling valve body 2 and screw-thread fit with it, valve rod 6 is fixedly connected with flap 5 in the one end being positioned at sampling cock body 2, its the other end is positioned at sampling valve body 2 extenal fixation and connects handwheel 9.
The two ends of pipeline valve body 4 adopt the mode such as flange or welding to be connected with system superintendent road, and its length is identical with the structure length of common valve, is convenient to change.
Sampling valve body 2 is positioned at pipeline valve body 4 and the part of the sphere of activities of valve rod 6 is provided with at least one through hole 20, and in the implementation case, through hole 20 is provided with two.
