Abstract
The utility model discloses a valve examination tool including a seamless steel pipe and a connecting assembly, the connecting assembly includes a pair of butt clamping plates and adjusting blocks arranged at the inner sides of the butt clamping plates, the pair of butt clamping plates are tensioned and fixed through the cooperation of studs and nuts, circular holes are arranged in the center of the butt clamping plates, the contact surfaces of the butt clamping plates and the adjusting blocks are in a spherical self-localization structure, guiding benches are arranged on the adjusting blocks and are sleeved with pads, through holes are arranged inside the adjusting blocks in the direction of the guiding benches, and one end, far away from the guiding bench, of each through hole is connected and fixed to the seamless steel pipe. The valve examination tool provided, which is simple in structure and low in cost, can be used in set and can meet the demands of a factory on the high-low temperature detection of a connection valve at the non-flange end.
Description
Technical field
The utility model relates to a kind of verifying attachment, is specifically related to a kind of valve examination frock, can play good end part seal effect to the high temperature of non-flange end connection valve and the check of ultralow temperature gas sealing ability.
Background technology
Along with the development of industrial technology, the duty parameter of the industries such as rock gas, Coal Chemical Industry (temperature, pressure etc.) requires also progressively to improve, to the future development of high temperature, ultralow temperature, high pressure.The market demand of high and low temperature valve is also in continuous increase.Because this type of special operation condition valve applying working condition is harsh, and medium is often inflammable, explosive, poisonous, so valve manufacturer and user also more and more pay attention to the sealing property of valve, generally all need in valve manufacturer factory, inspect in proportion the performance of valve by random samples, therefore the outfit of relevant inspection machine and check frock is particularly important, should carry out the check under normal temperature operating mode, also need to carry out the check under high and low temperature operating mode.
In prior art, the check of the valve connecting for flange end adopts the mode of blind flange sealing to check more, as shown in Figure 1, the valve that connects (socket weld, jam welding connect) for non-flange end, normal temperature check can adopt wafer type pump platform to carry out pump and test, but high and low temperature check is owing to will valve being heated or low-temperature deep, wafer type pump platform cannot be used, simultaneously owing to existing the temperature difference, pressure higher, so just need to adopt special frock to guarantee in the sealing of checking temperature and inspection pressure lower valve end.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of valve examination frock, can play good end part seal effect to the high temperature of non-flange end connection valve, normal temperature and the check of ultralow temperature gas sealing ability.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of valve examination frock, comprise weldless steel tube and coupling assembling, described coupling assembling comprises a pair of to clamping plate and the regulating block of being located at clamping plate inner side, describedly a pair of clamping plate are coordinated and are strained and fixed by double-screw bolt and nut, described clamping plate center is provided with to circular hole, described is sphere self positioning structure to the surface of contact of clamping plate and regulating block, described regulating block is provided with guide table, in described guide table, be arranged with pad, described regulating block inside is provided with through hole along guide table direction, described through hole is connected and fixed away from one end and the weldless steel tube of guide table.
In technique scheme, described sphere self positioning structure is: described is the sphere caving inward to the part contacting with regulating block on clamping plate, the sphere that is outwardly convex with the part that clamping plate are contacted on described regulating block.
In technique scheme, described is rectangle to clamping plate cross section, and its four angles are respectively equipped with circular hole, and described double-screw bolt is fixed by nut through circular hole and two ends.
In technique scheme, described regulating block and weldless steel tube are welded and fixed or are threaded connection fixing.
In technique scheme, the sealing position of described regulating block and pad processing concentric circles waterline, and guide table is taper, wherein, described pad adopts metal species pad, preferentially selects red copper pad.
Principle of work of the present utility model is: under the pretightning force providing at one group of double-screw bolt tension two ends clamping plate, between clamping plate, regulating block, pad and valve, all there is interaction force, make to seal between pad and valve end, thereby form an airtight pipe system, the valve that can connect non-flange end carries out a series of check work.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. valve examination frock of the present utility model is adopting sphere self positioning structure to clamping plate and regulating block surface of contact place, guaranteed clamping plate to make in the process of straining by double-screw bolt at the center of regulating block and tested valve all the time on a center line, avoided stressed when inconsistent in double-screw bolt tension process, cause the sealing surface discontinuity of each parts, and cause valve end connecting portion to leak, cannot carry out related check.
2. the sealing position of regulating block of the present utility model and metallic gasket processing concentric circles waterline, and guide table is taper, is equivalent to the effect of drafting angle, prevents that metallic gasket is difficult to take out because of distortion.
3. metallic gasket of the present utility model adopts red copper pad; red copper has the advantages that density is large, material is soft; cost with respect to conventional seal is cheaper; process simple and quick; and red copper pad is in the situation that playing sealing function, also has the effect of good compensating action and protection valve end face.
