Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
The utility model discloses a kind of sampler 1 and utilizes the sampler of this sampler.With reference to Fig. 2, sampler mainly comprises with lower member: sampler 1, material storage tank 2, pump 3, material are sent pipeline 4 and pump return line 5.
As shown in Figure 2, the annexation of above-mentioned all parts is: the outlet of material storage tank 2 connects pump 3, and pump 3 connects respectively material and sends pipeline 4 and pump return line 5.Comprise main return wire and auxiliary reflux line in parallel on the pump return line 5, wherein main return wire comprises the first gate valve 61, sampler 1 and the second gate valve 63 that successively series connection arranges, and the 3rd gate valve 62 is set on the auxiliary reflux line.
The concrete structure of sampler 1 is with reference to Fig. 3, and it comprises that mainly valve rod 11, valve gap 12, valve body 13, seal 14 and sample flow out pipeline 15.Wherein, seal 14 bottoms are back taper, can guarantee effectively to dredge by operating valve lever 11 under the sample flow outlet material obstruction condition.
As shown in Figure 3, valve body 13 bottoms are straight pipeline, are provided with secondary duct along the straight pipeline vertical direction, and valve rod 11 is arranged in the secondary duct, and are vertical with valve body 13 bottom straight pipelines.Valve body 13 secondary duct tops arranges valve gap 12, and valve gap 12 is tightly connected with secondary duct, and valve gap 12 tops comprise seal groove, and valve rod 11 is arranged in the seal groove, and the seal groove at valve gap 12 tops and valve gap 12 are connected by bolt tightening.
Secondary duct and straight pipeline junction comprise a through hole, and valve rod 11 bottoms are seal 14, and seal 14 is arranged in the through hole, and airtight setting between seal 14 and the through hole is by the movement in vertical direction of valve rod 11 along straight pipeline.The straight pipeline wall of through hole relative position has sample and flows out pipeline 15, and shape and seal 14 end shapes that sample flows out pipeline opening are complementary.
Because seal 14 bottoms are back taper, therefore sample flows out the sample outflow pipeline opening of pipeline 15 for sealing the inclined-plane, upper and lower displacement drive back taper seal 14 by valve rod 11 moves up and down, thereby realize back taper seal 14 with the open and close of the sample outflow pipeline opening of valve body 13 bottoms, realization seal 14 ends and sample flow out the airtight of pipeline opening and open.
With reference to Fig. 4-Fig. 7, leave the fluid free air space between seal 14 and the straight pipeline tube wall, especially, for valve body 13 interior materials during making seal 14 move down sealing still have enough actual internal areas, the maximum gauge of seal 14 is generally 0.05-0.9 times of valve body 13 internal diameters.
As shown in Figure 4 and Figure 5, when the end of seal 14 and sample flow out pipeline 15 when airtight, the fluid free air space under the closed condition is arranged, between seal 15 and the valve body 13 shown in the arrow locations among Fig. 5.
As shown in Figure 6 and Figure 7, when the end of seal 14 and sample flow out pipeline 15 when opening, the fluid free air space under the opening is arranged, between seal 15 and the valve body 13 shown in the arrow locations among Fig. 7.
On the other hand, sample flows out pipeline 15 and is welded on the valve body 13, is external diffusion shape, can prevent that sampler 1 from closing the rear section material because the fluid-tight problem that the existence of atmospheric pressure causes guarantees that sample is in sample outflow pipeline 15 and 13 delays of valve body.
The utility model is by the novel easily-crystallized stock sampler of design, and pump return line made corresponding change, the constant problem of sampling that can solve the sample cock obstruction and cause is conducive to solve the person and the environment hidden danger at Chemical Manufacture scene and improve employee's operating efficiency.
