Abstract
The invention discloses a high-temperature resistance sampling port sealing device, which comprises a sealing body in the shape of a circular truncated cone. The high temperature resistance sampling port sealing device is characterized in that a round penetrating sampling gun through hole is positioned along the axis of a sealing body. The high-temperature resistance sampling port sealing device adopts a circular truncated cone shape structure, and can adapt to sampling ports in various sizes required in the sampling specification. According to the high-temperature resistance sampling port sealing device, damage on the sealing device by high-temperature smoke can be effectively avoided by adopting fluororubber 246, and the high-temperature resistance sampling port sealing device has a simple structure and is convenient to implement. The high temperature resistance sampling port sealing device disclosed by the invention has the advantages of simple structure and the like, is convenient to use and is safe and reliable.
Description
Technical field
The present invention relates to a kind of device of the rifle sealing that is used to sample.
Background technique
At present, when the various high-temperature gases of collection detect sampling, often use a kind of rod sampling rifle.The process of sampling rifle collected specimens need be opened flue, inserts the sampling rifle, and is with the flue sealing, excessive to avoid flue gas then.Mostly most of sealing devices are to be formed by manufacturings such as plastics, corks.Under high temperature action, can go bad, thereby the gas of sampling produces secondary pollution in various degree, and during to monitoring high-temperature flue gas (more than 100 degree), the possibility of spontaneous combustion is arranged.
Summary of the invention
The invention provides a kind of solution of the above problems, a kind of easy-to-use high temperature resistant thief hatch seal arrangement simple in structure, safe is provided.
Technological scheme of the present invention provides a kind of high temperature resistant thief hatch seal arrangement, and the seal that it comprises frustoconic shape is characterized in that: the axis along said seal is provided with the circular sampling rifle through hole that connects.
Preferably, said seal is made up of left seal and right seal, a plane symmetry at the axis place of said left seal and the said relatively seal of right seal.
Preferably, said seal is made up of at least three branch seals, and all said minute seals include upper and lower end face and two sides that are positioned at said seal upper and lower end face, and two said sides include the axis of said seal.
Preferably, said seal is processed by fluororubber 246.Fluororubber 246, the domestic glue that is commonly called as No. 3, the trade mark VITON B of Du Pont is vinylidene, tetrafluoroethylene, hexafluoropropene terpolymer.246 fluorine glue are heat-resisting not worse than 26-41.The performance of 246 types is suitable after the rerum natura of 26-41 after 300 ℃ * 100 hours air heat ageings and the hot air aging in 300 ℃ * 100 hours, and its elongation at break can remain on about 100%, hardness 90～95 degree.246 types keep favorable elasticity 350 ℃ of hot air agings after 16 hours, keep favorable elasticity 400 ℃ of hot air agings after 110 minutes.
High temperature resistant thief hatch seal arrangement of the present invention adopts the frustoconic shape structure, can adapt to the multiple size of desired thief hatch in the sampling standard, and adopts fluororubber 246 can avoid the infringement of high-temperature flue gas to sealing device effectively, easy enforcement simple in structure.High temperature resistant thief hatch seal arrangement of the present invention has advantages such as simple in structure, easy to use, safe and reliable.
Description of drawings
Fig. 1 is the decomposing schematic representation of the preferred embodiment of high temperature resistant thief hatch seal arrangement of the present invention;
Fig. 2 is the combination schematic representation of the preferred embodiment of high temperature resistant thief hatch seal arrangement of the present invention;
Fig. 3 is that the present invention uses schematic representation.
Embodiment
Following specific embodiments of the invention is described in further detail.
As depicted in figs. 1 and 2, high temperature resistant thief hatch seal arrangement of the present invention comprises the seal 10 of frustoconic shape, is provided with the sampling rifle through hole 12 of circular perforation along the axis of seal 10.Seal 10 adopts fluororubber 246 to process.In the preferred embodiment of the present invention, seal 10 is made up of with right seal 16 left seal 14, arbitrary plane symmetry at the axis place of left seal 14 and right seal 16 relative seals 10.Promptly the axis along seal 10 becomes left and right sides two-part with seal 10 symmetry division, makes things convenient for manufacturing, also convenient the use.Only need as shown in Figure 3ly during use, left seal 14 is combined with right seal 16, get final product in the sampling rifle through hole 12 that the sampling rifle is clipped in the middle.Certainly, seal 10 also can cut into the part that a plurality of (three and more than) size is identical or vary in size along its axial direction, equally also can realize the object of the invention, can not be confined to present embodiment.In addition, left seal 14 can also adopt the auxiliary combination of modes such as bonding or buckle during with right seal 16 combinations, also can directly be stitched together, and leans on the mutual extrusion of itself and sample tap (not shown) to combine.At this moment, the branch seal after each is cut apart includes upper and lower end face and two sides that are positioned at seal 10 upper and lower end faces, and bi-side include the axis of seal 10, are general knowledge here, so not expression in detail.
Above embodiment is merely the present invention's a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
Claims (4)
1. high temperature resistant thief hatch seal arrangement, the seal that it comprises frustoconic shape is characterized in that: the axis along said seal is provided with the circular sampling rifle through hole that connects.
2. high temperature resistant thief hatch seal arrangement according to claim 1 is characterized in that: said seal is made up of left seal and right seal, arbitrary plane symmetry at the axis place of said left seal and the said relatively seal of right seal.
