Abstract
The utility model provides a calorimeter oxygen bullet bleed valve, includes handle portion and base part, and handle portion is as an organic whole by handle (1), external screw thread lead screw (2) and thimble (3) fixed connection in proper order, and the base part is that swivel nut (4) and swivel nut (4) lateral wall open exhaust port (5) that have and constitute, and external screw thread lead screw (2) and swivel nut (4) screw-thread fit, external screw thread lead screw (2) just open the position of exhaust port (5) and have breach (6), let external screw thread lead screw (2) lower part space and exhaust port (5) intercommunication. The utility model has the advantages of split type threaded connection, good interchangeability, strong practicability, broken thimble, capability of immediately replacing the handle part or welding the thimble, and no influence on the experimental efficiency; meanwhile, the cost is saved, if the thimble is broken, the original air release valve can be continuously used after welding, and the cost is low.
Description
Technical field
The utility model relates to combustion experiment instrument field, is specifically related to a kind of bleed valve of calorimeter oxygen bomb.
Background technique
At present, known normative document GB/T213-2008 " heat output determining method of coal " specifies, after oxygen bomb is tested in calorimeter, opens bleed valve, releases gas of combustion.Existing bleed valve as shown in Figure 1, when oxygen bomb needs venting, is held handle 1, bleed valve is placed on oxygen bomb air outlet end, firmly pressure, oxygen bomb valve backs down by thimble 2, and waste gas is discharged by relief opening, relief opening connects tracheae again, makes waste gas smooth discharge to outdoor, avoids room air pollution.Existing bleed valve is integrated device, and thimble 2 easily ruptures, once thimble 2 ruptures, cannot weld thimble 2, whole bleed valve cannot use.If laboratory is without stand-by provision, experiment cannot be continued, affect efficiency.
Model utility content
The utility model, for the deficiencies in the prior art, proposes shaping, the interchangeability better calorimeter oxygen bomb bleed valve of a kind of assembling.
Concrete technological scheme is as follows:
A kind of calorimeter oxygen bomb bleed valve, its key is: comprise handling portion and base portion, described handling portion is by handle (1), outside thread screw mandrel (2) and thimble (3) are fixedly connected sequentially and are integrated, described base portion is that the relief opening (5) that swivel nut (4) and swivel nut (4) sidewall have is formed, described outside thread screw mandrel (2) and swivel nut (4) screw-thread fit, described outside thread screw mandrel (2) just has breach (6) to the position of relief opening (5), described outside thread screw mandrel (2) lower space is allowed to be communicated with relief opening (5).Handling portion and the split type setting of base portion two-part, Screw assembly, can light Assembly And Disassembly, in every day use process, handle and base are all integrated, and thimble is once fracture, handling portion can be screwed out from base immediately, weld thimble, can continue very soon to use this device.
Above-mentioned swivel nut (4) endoporus is made up of enlarged diameter section and reduced diameter section two-part, described outside thread screw mandrel (2) is threaded with swivel nut (4) enlarged diameter section, and described relief opening (5) is positioned at swivel nut (4) enlarged diameter section lower end.The position of relief opening need on internal thread, if position is too low, gas will be revealed by lower end mouth, and harmful gas has directly come indoor.
Beneficial effect is: the split type setting of the utility model is threaded, and interchangeability is good, practical, and thimble ruptures, and can change handling portion or welding thimble immediately, can not affect conventional efficient; Simultaneously cost-saving, if thimble fracture, after welding, can continue to use original bleed valve, cost cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation before improving;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 2: a kind of calorimeter oxygen bomb bleed valve, be made up of handling portion and base portion, described handling portion is fixedly connected sequentially by handle 1, outside thread screw mandrel 2 and thimble 3 and is integrated, described base portion is that the relief opening 5 that swivel nut 4 and swivel nut 4 sidewall have is formed, described outside thread screw mandrel 2 and swivel nut 4 screw-thread fit, described outside thread screw mandrel 2 just has breach 6 to the position of relief opening 5, allows described outside thread screw mandrel 2 lower space be communicated with relief opening 5.Described swivel nut 4 endoporus is made up of enlarged diameter section and reduced diameter section two-part, and described outside thread screw mandrel 2 is threaded with swivel nut 4 enlarged diameter section, and described relief opening 5 is positioned at swivel nut 4 enlarged diameter section lower end.During machining gap 6, first shank portion and base portion are assembled, aim at relief opening side, the breach 6 on reprocessing outside thread screw mandrel 2, just can ensure that breach 6 can not rotate to other orientation.If not machining gap 6, gas cannot be discharged.
