Abstract
The utility model relates to a storage barrel, in particular to a vent valve for a storage barrel. According to the technical proposal provided by the utility model, a positioning groove is formed on an elastic body; and the elastic body adopts a columnar body. One end of the columnar body adopts a disc-shaped body, and the positioning groove is formed at one end the columnar body close to the disc-shaped body. A tapered cone is arranged on the elastic body in the position close to the positioning groove, and the diameter of the end of the cone close to the positioning groove is larger than that of the other end thereof. Through an elastic valve spool arranged on the barrel wall, the pressure balance inside and outside the barrel is realized, so that the deformation of the barrel wall due to sinkage or collapse is avoided.
Description
Technical field
The utility model relates to a kind of Object storing drum, specifically a kind of vent valve that is used for Object storing drum.
Background technology
Steel drum along with the reduction of ambient temperature, forms negative pressure in the bucket after the hot filling sealing, very easily steel drum is inhaled flat distortion.For avoiding this type of accident to take place, manufacturer generally dashes an aperture at bung at present, on aperture, revolve corresponding screw and gasket seal again, when ambient temperature reduces, to unscrew screw ventilative in good time, make barrel internal gas pressure by a ventilative ftercompction of aperture and the outer air pressure balance of bucket, prevent that steel drum from inhaling the effect of flat distortion thereby reach.
The defective of this ventilative mode is: 1, after stamping out breather hole on the bung, because the most air storage of steel drum after the actual can, if run into the rainy day, bung is easy to ponding, indivedual breather holes are not having under the complete leak free state, and the sewage that is mingled with dust can be seeped in the bucket, causes contamination of products, if the product of can and water attack, the consequence that causes is with hardly imaginable.2, ventilative packing seal generally is made up of thread-forming screw, rubber sheet gasket and plain cushion, be spun on screwing hermetic on the bung by self-tapping screw, the shortcoming of this connection mode is that assembly is many, and thread-forming screw easily produces scrap metal when revolving bung, thereby the cleanliness level in the bucket is polluted.
Summary of the invention
The purpose of this utility model is a kind of vent valve that is used for Object storing drum of design, by a kind of elastomeric spool is set on the bucket wall, realizes the balance of barrel inner and outer air pressure, prevents that barrel wall from being inhaled flat distortion.
Technical scheme according to the utility model provides is provided with positioning groove on elastic body; Described elastic body is a column.
One end of described column is a discoid body, and described positioning groove is arranged on an end of close discoid body on the column.The centrum of band tapering is set near the position of positioning groove on elastic body, and the diameter of an end of the close positioning groove of described centrum is greater than the diameter of the other end.
Described elastic body is positioned at the air extractor vent that is arranged on the barrel body wall; Described staving comprises ladle body, be positioned at the bucket end of ladle body bottom and be positioned at the bung of ladle body upper end; Described air extractor vent is arranged on ladle body or the bung or the wall at the bucket end; A described elastomeric end is positioned at ladle body, and the other end is positioned at the outside of ladle body.
Outside or inwardly outstanding annular protrusion is set on the air extractor vent of ladle body, and shrink to the center of air extractor vent the end of described annular protrusion, forms contraction flow region, and described annular protrusion and contraction flow region thereof are embedded in the described positioning groove.Between the inwall of the surface of positioning groove and annular protrusion, form the gap.
The utility model has the advantages that, elastic body is embedded in the air extractor vent on the ladle body, and annular protrusion on the air extractor vent is embedded in the positioning groove on the elastic body form sealing.When producing negative pressure and other reason and cause in the bucket negative pressure because of cooling behind the steel drum hot filling, because the bucket wall of ladle body deforms, air extractor vent junction on elastic body and the ladle body can produce the gap and make steel drum suck extraneous atmosphere, thereby reach the balance of inner and outer air pressure, prevented that steel drum from being inhaled flat distortion.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
As shown in the figure: the described vent valve that is used for Object storing drum, comprise ladle body (1), be positioned at the bucket end of ladle body bottom and be positioned at the bung of ladle body (1) upper end, on the wall of ladle body 1, air extractor vent is set, in described air extractor vent, place elastic body, a described elastomeric end is positioned at ladle body 1, and the other end is positioned at the outside of ladle body 1.Positioning groove 4 is set on elastic body, outwards is provided with on the air extractor vent of ladle body 1 or inwardly outstanding annular protrusion 8, described annular protrusion 8 is embedded in the described positioning groove 4.Between the inwall of the surface of positioning groove 4 and annular protrusion 8, form the gap.
The centrum 6 of band tapering is set at the position of annular protrusion 8 close positioning grooves 4, and the diameter of an end of described centrum 6 close positioning grooves 4 is greater than the diameter of the other end.Form a barb-like structure, when inserting elastic body in the air extractor vent, centrum 6 helps elastomeric insertion, and after insertion, elastic body is not easy to come off easily because of the barb-like structure of centrum 6 again.
Described elastic body 2 can be made into column 5, and at the end formation discoid body 2 of described column 5, and the end near discoid body 2 is provided with positioning groove 4 on column 5; Shrink to the center of air extractor vent the end of described annular protrusion 8, forms contraction flow region 7, and described annular protrusion 8 and contraction flow region 7 thereof are embedded in the described positioning groove 4.During use, Object storing drum is behind the process hot filling, As time goes on, temperature can descend because of the ambient temperature in the external world in the bucket, after temperature descends, is in negative pressure state in the bucket, the bucket wall that causes ladle body 1 is to internal strain, can be between bucket wall and the elastomeric discoid body 2 and the column 5 of ladle body 1 after the distortion formation gap 3, outside air is entered in the bucket, reach a barrel internal and external equilibrium.Behind the inside and outside gas pressure balancing of ladle body 1, the bucket wall of ladle body 1 restores to the original state again, makes 1 of elastic body and ladle body return to original sealing state again.
