Abstract
The utility model discloses a gas sampler, belonging to the sampler; the structure of the gas sampler be composed of a valve body, a valve stem, and a handwheel, the valve stem is installed in the valve body, and the top of the valve stem is equipped with the handwheel; the top of the valve body is equipped with a pressing cap, the pressing cap connects the valve body and the valve stem through a nut sleeve, and a sealing ring is installed between the bottom of the nut sleeve and the valve body; the bottom of the valve stem is connected with a valve base in the valve body, and the valve base is connected with a backing board at the bottom of the valve body cavity; the outside of the bottom of the valve body is equipped with a base, and a gasket is installed between the bottom of the valve body and the base. Compared with the prior art, the gas sampler of the utility model has the advantages of reasonable design, simple structure, and good sealing property, so the gas sampler has very great generalization and use value.
Description
Technical field
The utility model relates to a kind of sampling thief, specifically a kind of gas sampler.
Background technology
The sampling thief that uses medium high pressure ejection when regular meeting appears at sampling at present, inconvenience sampling, even situation about can hurt sb.'s feelings; And the sampling thief of prior art has mostly reveals serious disadvantage, and its main cause is to contain hard particles in the sampling media, causes existing sampling thief sealing not thorough, leakage problem occurs in operate as normal.
Summary of the invention
The purpose of this utility model is at above weak point, and a kind of gas sampler of simple in structure, good seal performance is provided.
The technical scheme that its technical matters that solves the utility model adopts is: valve rod is arranged in the valve body, the top of valve rod is provided with handwheel, the top of valve body is provided with pressure cap, pressure cap links together valve body and valve rod by nut sleeve, be provided with O-ring seal between the bottom of nut sleeve and the valve body, the bottom of valve rod joins with the valve seat that is arranged in the valve body, valve seat joins with the collet that is arranged on the body cavity bottom, the valve body bottom is outside equipped with base, is provided with sealing gasket between the bottom of valve body and the base; Side of valve body is provided with outlet; The cylinder of stem bottom and the endoporus of valve seat are interference fit.
During use, rotation hand wheel descends valve rod, and its bottom cylinder inserts in the valve seat endoporus, forms sealing; The repercussion rotation hand wheel, valve rod rises, and stem bottom and valve seat are thrown off, and the medium in the pipeline flows in the sampling thief valve body by the base endoporus, flows out by outlet, thereby samples.
The gas sampler of this structure is when opening, and medium can steadily flow out, and can splash not hurt sb.'s feelings; When closing, can not be not closed completely because of in the medium hard particles being arranged yet, situation about revealing appears.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a kind of structural representation of gas sampler.
Embodiment
Explain below with reference to Figure of description a kind of gas sampler of the present utility model being done.
A kind of gas sampler of the present utility model, its structure is by valve body 5, valve rod 6 and handwheel 11 constitute, valve rod 6 is arranged in the valve body 5, the top of valve rod 6 is provided with handwheel 11, the top of valve body 5 is provided with pressure cap 9, pressure cap 9 links together valve body 5 and valve rod 6 by nut sleeve 10, be provided with O-ring seal 8 between the bottom of nut sleeve 10 and the valve body 5, the bottom of valve rod 6 joins with the valve seat 4 that is arranged in the valve body 5, valve seat 4 joins with the collet 3 that is arranged on valve body 5 intracavity bottoms, valve body 5 bottoms are outside equipped with base 1, are provided with sealing gasket 2 between the bottom of valve body 5 and the base 1; The side of valve body 5 is provided with outlet 7; The cylinder of valve rod 6 bottoms and the endoporus of valve seat 4 are interference fit.
Its processing and fabricating of gas sampler of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
