Abstract
The utility model relates to a rapid vacuum on-line sampling device which comprises a sampling valve and a sampler. The sampling valve comprises a valve body, a valve cover, a valve stem, a valve base and a valve slap. The sampler comprises a housing, a piston barrel, a piston, a sucker and a sucker displacement controller; a sealing connection mechanism is arranged between the housing of the sampler and the valve body of the sampling valve; the piston barrel is fixedly connected at one end of the housing; the inner bore of the sucker is communicated with the inner cavity of the piston barrel; the sucker displacement controller is arranged at the middle part of the sucker; the end part of the sucker is rested against the valve flap; and a sealing mechanism is arranged between the housing and the sucking port of the lateral wall of the end part of the sucker. The sampling device hermetically isolates the sample from the external environment, protects the sample from being contaminated by other media in the external environment, prevents the environmental pollution and the potential safety problem caused by the leakage of the sampling medium, and has the advantages of authentic sample and safe operation. The rapid vacuum on-line sampling device is applied to the pipeline of highly-volatile, flammable, explosive and noxious liquid media.
Description
Technical field
The utility model relates to the online sampler of a kind of pipeline medium.The sampler of medium pipelines such as strongly corrosion liquid media such as it is volatile, inflammable, explosive, poisonous that the utility model is applicable to and medicine, food.
Background technology
On the medium transport pipelines such as, food volatile, inflammable, explosive, poisonous and medical at some, need carry out sample examination, analysis to medium, existing sampling method is to add a long pipe to carry out open sampling operation on common stop valve or gate valve or ball valve.What this sampling method used is antivacuum sample valve, can not guarantee the authenticity of the dielectric sample of getting.And sampling process causes environmental pollution easily and to the safety problem of hazard to person.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of online sampler of true, safe fast vacuum of taking a sample is provided.
The technical solution of the utility model comprises a sample valve and a sampler, sample valve comprises valve body, valve gap, valve rod, valve seat, flap, mainly be that sampler is made up of housing, piston cylinder, piston, suction pipe and suction pipe displacement control device, be provided with sealing and connecting device between the housing of sampler and the valve body of sample valve, piston cylinder is fixedly connected on an end of housing, the suction pipe endoporus is communicated with the piston cylinder inner chamber, the suction pipe middle part is provided with the suction pipe displacement control device, the end and the flap of suction pipe contact, and are provided with packoff between the suction hole of housing and suction pipe end sidewalls.
In above technical scheme, the suction pipe displacement control device is made up of the slide block and the slide block joystick that are fixed on the suction pipe.
Advantage of the present utility model is that sampler and sample valve are tightly connected when sampling, sample after the sampling and extraneous seal isolation, avoided sample to be subjected to the pollution of extraneous other media and sampling medium to leak pollution and safety problem to environment, true, the handling safety of its sampling.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
