Abstract
The utility model relates to a piston sealing structure of a mercury-free high-pressure physical analyzer. One pair of sealing rings is arranged below a sampling barrel of the analyzer, wherein a sealing regulating rod is connected at lower part of the sealing ring; a check nut is arranged at the outer side of the regulating rod; the lower part of the regulating rod is a cylinder which is connected with a hydraulic device; and a high-pressure connector is arranged in the cylinder. The piston sealing structure is convenient and quick to seal, has good sealing effect, is convenient to regulate the sealing ring and is easy to change the sealing ring; the sealing ring is made of a special material, so that the piston sealing structure resists high temperature, resists corrosion and has long service life.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to a kind of no mercury high pressure property ANALYZER piston sealing structure.
Background technique
Because the sealing requirements of no mercury high pressure property ANALYZER is higher; If the bad meeting of sealing effect directly influences the effect and the result of whole test when test; Test data also error can occur, and existing seal arrangement generally adopts viton seal ring to seal, and reaches the effect of sealing with bolt extruding fixed seal ring; This sealing structure circle is inconvenient to regulate; And viton seal ring non-refractory, perishable, working life are short, make that seal ring needs often to change and change complicated operation, have reduced the reliability of ANALYZER.
The model utility content
The utility model provides a kind of good sealing effect, easy to operate no mercury high pressure property ANALYZER piston sealing structure in order to overcome the above problems.
The technological scheme of the utility model is: the sample tube below of said ANALYZER is provided with a pair of seal ring; Said seal ring bottom is connected with the sealing adjustable lever; Adjustable lever is provided with fastening screw nut outward, and the adjustable lever bottom is oil cylinder and is connected to hydraulic pressure installation, is provided with the high pressure connection mouth in the oil cylinder.
The utility model seal operation is fast convenient, good sealing effect, and convenient the adjusting also of seal ring changed easily, and said seal ring adopts special material to process, and is high temperature resistant, corrosion-resistant, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is the sample tube among the figure, the 2nd, and seal ring, the 3rd, fastening screw nut, the 4th, sealing adjustable lever, the 5th, oil cylinder, the 6th, high pressure connection mouth, the 7th, oil hydraulic pump.
Embodiment
No mercury high pressure property ANALYZER piston sealing structure; Sample tube 1 below of said ANALYZER is provided with a pair of teflin ring 2; Said seal ring 2 bottoms are connected with sealing adjustable lever 4; Be provided with fastening screw nut 3 outside the sealing adjustable lever 4, adjustable lever 4 bottoms are oil cylinder 5 and are connected to oil hydraulic pump 7, are provided with high pressure connection mouth 6 in the oil cylinder 5.High pressure connection mouth 6 is connected with external oil hydraulic pump 7, and the primer fluid press pump 7 then, in oil cylinder 5, carry highly pressurised liquid; Under the effect of pressure, sealing adjustable lever 4 is upwards passed, and makes seal ring 2 compacted; Fastening screw nut 3 was also moved up by drive when sealing adjustable lever 4 moved up, and at this moment, fastening screw nut 3 was tightened downwards; At this moment lay down the pressure in the oil cylinder 5, just can guarantee to seal adjustable lever 4 and compress seal ring 2 sealings.
Claims (1)
