Abstract
The invention discloses an on-line manual negative pressure sampling system which comprises a material feeding valve, wherein the input end of the material feeding valve is connected with a sampling opening of a technical pipeline, and the output end of the material feeding valve is connected with a first connection opening of a three-way sampling pipe; a second connection opening of the three-way sampling pipe is connected with the input end of a sampling valve; a third connection opening of the three-way sampling pipe is connected with the input end of an emptying valve; a distance between the input end of the material feeding valve and the sampling opening of the technical pipeline is 5-15mm; a distance between the output end of the material feeding valve and the first connection opening of the three-way sampling pipe is 8-20mm. The on-line manual negative pressure sampling system does not need vacuum power and only depends on gravity of the material, so that sampling is more convenient, the cost is lower, the safety is high, and the generality is higher.
Description
Technical field
The present invention relates to a kind of online Manual negative pressure sampling system.
Background technology
In current a lot of pharmacy or food service industry, have concentrated technique for raw material in the production technology of product, the pressure in General System is negative pressure, causes being difficult under normal circumstances carrying out sample analysis to the material in producing; And the way of routine uses vacuum material sucking-off, sampling prepares more loaded down with trivial details, needs to connect vacuum pipe and material sample connection; Sampling mode conventional at present in addition needs vacuum equipment, needs artificially to judge the suction time, be easy to a material and be directly drawn onto in vacuum pipe when sampling.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of online Manual negative pressure sampling system.
The present invention for achieving the above object, adopts following technical scheme: a kind of Manual negative pressure on-line period system, comprises inlet valve; The input end of described inlet valve is connected with process pipe sample tap, and its output terminal is connected with the first connector of threeway stopple coupon; Second connector of described threeway stopple coupon is connected with the input end of sample valve, and the 3rd connector of described threeway stopple coupon is connected with the input end of atmospheric valve; Wherein, the distance between the input end of described inlet valve and described process pipe sample tap is between 5-15mm, and the distance between the output terminal of described inlet valve and the first connector of described threeway stopple coupon is between 8-20mm.
Beneficial effect of the present invention: sampling below atmospheric pressure system of the present invention does not need the power of vacuum, dependence be the gravity of material itself, sampling ratio is more convenient, and cost compare is low, and security is high, universal stronger.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the function of the present invention.
Embodiment
Shown in Fig. 1, relate to a kind of Manual negative pressure on-line period system, comprise inlet valve 1; The input end of described inlet valve 1 is connected with process pipe sample tap 5, and its output terminal is connected with the first connector of threeway stopple coupon 4; Second connector of described threeway stopple coupon 4 is connected with the input end of sample valve 3, and the 3rd connector of described threeway stopple coupon 4 is connected with the input end of atmospheric valve 2; Wherein, the distance between the input end of described inlet valve 1 and described process pipe sample tap 5 is between 5-15mm, and the distance between the output terminal of described inlet valve 1 and the first connector of described threeway stopple coupon 4 is between 8-20mm.
During sampling, first make in sampling system consistent with system process manifold pressure by opening inlet valve 1, rely on the deadweight of material, material is made to enter in threeway stopple coupon 4 road by the first connector of threeway stopple coupon 4, closing inlet valve 1 subsequently makes material remain in threeway stopple coupon 4, finally opens sample valve 3 and atmospheric valve 2, after recovering atmospheric pressure in threeway stopple coupon 4, material flows in sampling container by sample valve 3 again, completes sampling.After terminating sampling, keep opening of sample valve 3, close atmospheric valve 2, open inlet valve 1, if any the material do not discharged, owing to having negative pressure in system process pipeline, remaining material will be sucked back in system process pipeline, avoid the real-time of the material of the waste of material and the lower sub-sampling of guarantee.Because the distance between the input end of inlet valve 1 and sample tap is arranged between 5-15mm, distance between its output terminal and the first connector of threeway stopple coupon 4 is arranged between 8-20mm, make material almost there is no dead point when inlet valve 1, avoid feed blocking system.
