Abstract
The utility model discloses a negative pressure apparatus sampling device. The sampling device comprises a spherical sampler, wherein a through hole is formed on the casing of the spherical sampler; and a rubber plug A is arranged in the through hole. A pipe is connected with the casing of the spherical sampler, and a flange plate A is arranged on one end of the pipe. A pipe is connected with one side of the negative pressure apparatus, a pipe valve is arranged on the pipe; and a flange plate B is arranged on one end of the pipe. The flange plate A is fixedly connected with the flange plate B as a whole. A through hole is also formed on the upper end face of the negative pressure apparatus; a rubber plug B is arranged in the through hole; and a discharge valve is arranged on the lower end of the negative pressure apparatus. When in use, the rubber plug A and the rubber plug B are inserted tightly; then the discharge valve on the lower end of the negative pressure apparatus is opened; the pipe valve is opened, so that liquid in the negative pressure apparatus flows to the sampler under pressure; and the sampler is filled with the process medium after a period of time. The sampling device provided by the utility model can extract the process medium under negative pressure, and has the advantages of simple operation, and stable and reliable work.
Description
Technical field
The utility model relates to the device that purifying phosphoric acid is produced, especially a kind of negative pressure equipment sampler.
Background technology
In the purifying phosphoric acid production run, more adopt the operations such as Vacuum Concentration, vacuum distillation, negative pressure rectifying, some vacuum tightness even reaches 11kpa, for the ease of controlling in the middle of producing, need under negative pressure state, processing medium be taken out and detect, but can't take out in on-the-spot actual production, just can not analyze producing pilot process, can not realize accurate control, so just cause product energy consumption too high, perhaps produce percent defective higher.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of negative pressure equipment sampler, processing medium can be taken out under negative pressure state to guarantee equipment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model: a kind of negative pressure equipment sampler, comprise spherical sampler, be provided with through hole on the housing of spherical sampler, be provided with plug A in this through hole, at the housing upper joint pipeline of spherical sampler, an end of pipeline is provided with ring flange A; A side at negative pressure equipment also is connected with pipeline, be provided with pipe valve on this pipeline, an end at this pipeline is provided with ring flange B, ring flange A docks with ring flange B and is fixed as one, upper surface at negative pressure equipment also is provided with through hole, be provided with plug B in this through hole, be provided with baiting valve in the lower end of negative pressure equipment.
Adopt said apparatus, at first jam-pack plug A and plug B, open the baiting valve of equipment lower end, then open pipe valve, the pressure of sampler the inside will be consistent with the vacuum tightness in negative pressure equipment, liquid in negative pressure equipment flows to sampler under the effect of pressure, after after a while, sampler will be full of processing medium fully, then close baiting valve, close again pipe valve, open plug A, just can take out medium and detect.
This device can take out processing medium under negative pressure state, and simple to operate, working stability is reliable.
