Embodiment Construction
[0016] according to figure 1 one Figure 5 As shown, the sampling head 1 and the flow pipe 7 are sealed and welded firmly as one. The valve seat 3 and the matching flange 6 are set outside the head pipe 7, an O-shaped rubber sealing ring 5 is installed between the two, and the bolt 4 is fastened to connect, and the matching flange 6 is welded firmly on the head pipe 7 On the outer diameter, it forms the head pipe assembly. The main shaft guide bushing 8 stretches into the inner diameter of the flow pipe 7, and the sealing welding is firmly connected. Cylindrical fluororubber bushing 9 is pressed into the main shaft guide bushing 8, and is pressed by the bush pressing part 10, and the bushing pressing part 10 and the main shaft guiding bushing 8 are connected by spot welding. The cover plate 11 is firmly welded on the outer diameter of the flow pipe 7, the cylinder fixing part 16 is installed at the end of the cover plate 11, fixed with the fixing screw 15, the cylinder fixi...

The invention discloses a pneumatic slurry sampling valve with an integrated internally-hung special sample cup. The pneumatic slurry sampling valve comprises a slurry flowing tube assembly 1, a main shaft assembly 2, a cover plate assembly 3, an internally-hung special sample cup assembly 4, a solenoid valve and a thin reciprocating adjustable-stroke cylinder, wherein a slurry outlet tube of a slurry flowing tube (7) in the slurry flowing tube assembly (1) is an inclined slurry outlet tube, wherein an included angle is 110 degrees; a cup cover (24) in the internally-hung special sample cup assembly (4) is connected with the tail end of the inclined slurry outlet tube of the slurry flowing tube (7) in a sealing manner, and an L-shaped hole of a special sample cup (26) is connected with a cup pin column (25) at the inner side of the cup cover. The pneumatic slurry sampling valve has the advantages of accuracy in sampling, no blockage, no washing, low labour intensity of operators, simplicity in operation, and safety. The pneumatic slurry sampling valve is remarkably characterized by ensuring that the operators online work under safe and clean production conditions.
Description
technical field [0001] The invention relates to the field of papermaking machinery, in particular to an electric and pneumatic device for on-line sampling of pulp slurry samples, and is equipped with a pneumatic slurry sampling valve with an integrated inner hanging sample cup. Background technique [0002] In the field of papermaking, when pulp slurry samples are sampled online, no matter whether manual operation, electric or pneumatic operation is adopted, laboratory personnel now hold containers of different sizes, and there is no container of uniform size for sampling. Due to the high temperature of the slurry at the sampling point, slurry splashing occurs when receiving the material, which is easy to cause burns to the operator, causing potential safety hazards, and cannot achieve safe and clean production. The same kind of foreign products do not have this configuration. The patent No. is 01252630.4) automatic slurry sampling valve has the long distance between the di...
