Abstract
The utility model relates to an eccentric disc clamp and cylinder inverted top type safety valve check cartridge, which comprises a bracket, a stand column and a cylinder assembly, wherein, the cylinder assembly is arranged bottom up on the upper rack of the bracket and the piston rod of the cylinder packs out downwards; the stand column consists of two stand columns with the top end of each stand column provided with an eccentric disc having a clamp for locking the flange neck of the safety valve waiting for checking, i.e. the eccentric disc is eccentrically arranged at the top end of the stand column; the lower part of the stand column is provided with transverse rods fixedly connected each other with the transverse rod center fixedly connected with the cylinder piston rod. The check cartridge provided by the utility model is a clamping mechanism suitable for normal-temperature low-pressure safety valve check platform and has the advantages of that: (1) only one gasket is adopted to replace a plurality of gaskets; (2) eccentricity mode of the eccentric disc is applied for adapting to different safety valve caliber; (3) a two-clamp structure is used to replace three--clamp structure; (4) steel rings of different height are utilized to fit installation flanges of various thickness and size; (5) the clamping mechanism is stable and reliable; (6) parts and components of the clamping mechanism are reduced.
Description
Technical field
The utility model relates to valve detection equipment, particularly a kind of eccentric disc card base and the cylinder formula of falling top verification deck to safety valve testing.
Background technology
When safety valve is located in verification, need the location, clamp and sealing.The clamping structure of present various normal temperature safety valve testing platforms has following three kinds:
1. screw retention by hand, its labour intensity is big, and efficient is low.
2. clamp by pneumatic just top formula, cylinder will up push up.
3. by just top formula clamping of hydraulic pressure, oil cylinder also will up push up.
Above-mentioned back two kinds of clamping modes need be fit to the movably card base and the heavy chuck of different bores, also need to adapt to the center cushion block of various bores, its bad adaptability, and verification work is very loaded down with trivial details.
Summary of the invention
In order to overcome the existing shortcoming of above-mentioned clamping structure, task of the present utility model provides a kind of improved eccentric disc card base and the cylinder formula of falling top safety valve testing deck, and it has solved the loaded down with trivial details problem of clamping mode bad adaptability, verification of existing safety valve testing platform.
The technical solution of the utility model is as follows:
A kind of eccentric disc card base and the cylinder formula of falling top safety valve testing deck, it comprises support, column and cylinder assembly, and described cylinder assembly is inverted in support and puts on the shelf, and cylinder piston rod ejects downwards and puts; Described column is made up of two columns, each column top be equipped with the band card base to block by the eccentric disc at verification safety valve neck flange place, be the eccentric disc partial center be installed in the column top, the cross bar that is mutually permanently connected is equipped with in the column bottom, cross bar center and cylinder piston rod are affixed.
Verification deck of the present utility model be a kind ofly be applicable in the normal temperature, the clamp system of low-pressure safety valve checking table, it has following advantage:
1. only need a sealing gasket just to replace a plurality of sealing gaskets.
2. use the degree of eccentricity mode of eccentric disc, to adapt to different safety valve bores.
3. replace three card base structures with two card base structures.
4. adopt different steel rings just to adapt to the mounting flange of different thickness sizes.
5. clamp system is reliable and stable.
6. the parts of clamp system have been reduced.
Description of drawings
Accompanying drawing is the structural representation of a kind of eccentric disc card base of the present utility model and the cylinder formula of falling top safety valve testing deck.
Embodiment
Referring to accompanying drawing, the utility model is a kind of eccentric disc card base and the cylinder formula of falling top safety valve testing deck, and it is equipped with support 10, column 4 and cylinder assembly 2.Cylinder assembly 2 is inverted in support 10 and puts on the shelf, and cylinder piston rod 21 ejects downwards and puts.
Column 4 is made up of two columns.Eccentric disc 8 is equipped with on each column 4 top, is installed in column 4 tops eccentric disc 8 partial centers, and the card base of eccentric disc 8 can block by the mounting flange neck place of verification safety valve 5.When installing by verification safety valve 5, with the moving eccentric disc 8 of hand-screw, by different degree of eccentricity to be fit to different flange diameter.As shown in FIG., be installed between two columns 4 by verification safety valve 5.Two column 4 bottoms a cross bar that is mutually permanently connected 9 has been installed, cross bar 9 centers and cylinder piston rod 21 are affixed.
The steel ring 1 of scalable height is housed between eccentric disc 8 bottom surfaces and column 4 tops, is encased inside the stroke range of the steel ring 1 of differing heights, and is fit to different flange thickness sizes with the cooperation cylinder.Eccentric disc 8 connects with column 4 by screw 6, and this screw 6 can be tightened or outward winding by hand.
Be installed in the cylinder assembly 2 that support 10 is put on the shelf, its end face is equipped with the sealing gasket 3 of band location chromosphere.Sealing gasket 3 is round gaskets, and its bottom surface is a metal material, so that bear snap-in force.On sealing gasket 3, apply or pasted the concentric circles of different colours, be convenient to by the location of verification safety valve 5 and sealing.
Copper sheathing 7 all is equipped with on top at each column 4.
When using the utility model, to be installed on this verification deck by the verification safety valve, and this valve positioned, compresses and seal, owing to the mounting flange that is had different bores and different thickness sizes by the verification safety valve, therefore must roughly press concentric circles to the center, rotate two eccentric discs on the column then, make the limit of eccentric disc change safety valve neck flange place over to.Operation cylinder gauge tap makes gas feed cylinder top, and after piston moved, cylinder piston rod just ejected downwards, and drove cross bar, and then made column spur eccentric disc downwards, thereby the fastening safety valve is finished the preceding job procedure of ventilation verification thus.After to be verified the finishing, unclamp cylinder and can take off safety valve.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim variation, the modification of the foregoing description.
