Abstract
The utility model discloses a kind of plastic barrels of internal negative pressure self-balancing, including prick hoop, bung, staving, polybag and unidirectional rubber valve；The utility model can well solve the cooling problem for causing to fall into plastic barrel body of thermal material, have the advantages that setting is reasonable, easy to use.
Description
Technical field
The present invention relates to plastic barrel technical field, espespecially a kind of plastic barrel of internal negative pressure self-balancing.
Background technique
Pail pack refers to all kinds of barreled packing containers, is mainly used for holding various liquid form products, the most commonly used is
The iron pail pack and plastic barrel of 200L often uses plastic barrel in production industries such as chemical industry, medicine, lubricating oil
It holds raw materials for production or finished product to be easy to cause in plastic barrel body and fall into after the higher raw material of temperature or finished product cool down, gives raw materials for production
Or transport, use or the storage of finished product are made troubles.For this reason, it may be necessary to a kind of plastic barrel, solve the higher raw material of temperature or
The problem of staving invagination is easy to happen after finished product is cooling.
Summary of the invention
The purpose of the present invention is to provide a kind of plastic barrels of internal negative pressure self-balancing.
To achieve the goals above, a kind of technical solution of the invention are as follows: plastics package of internal negative pressure self-balancing
Bucket includes pricking hoop, bung, staving, polybag and unidirectional rubber valve.
The bundle hoop is provided with knob；The bung is provided with internal screw thread, and bung is also provided with along side；Described
The top of staving set gradually screw thread while and it is lower along while, screw thread side be provided with external screw thread, screw thread while it is lower along while between also set
Mounting hole is set；The polybag is placed in staving, and the unidirectional rubber valve is installed in mounting hole；The unidirectional rubber
Glue valve includes bonnet and valve body, and the right end of valve body is provided with bonnet, and the valve chamber of connection is provided in valve body and in bonnet, and valve body exists
The left side of valve chamber is provided with the sealing of closure, and the left end both sides of valve body are provided with the section for being parallel to sealing.
The working principle of the invention is: in use, feed liquid is injected in the polybag in staving 3, cotton rope tightens polybag
Sack, bung is attached by screw thread and screw thread side, prick hoop by the bung of fitting along while under staving along while pass through drawing
Hand tightens, and after the feed liquid temperature in polybag declines, material liquid volume is shunk, the intracorporal drop of pressure of bucket, the intracorporal pressure of bucket
Pressure outside lower than staving, sealing opens under the action of internal and external pressure difference, and outside air enters in staving, until inside and outside staving
Pressure balance, sealing closure, avoid the intracorporal drop of pressure of bucket make in plastic barrel body fall into situation occur.
Beneficial aspects of the invention are: the present invention, which can well solve thermal material cooling, causes that falls into plastic barrel body to ask
Topic has the advantages that setting is reasonable, easy to use.
Detailed description of the invention
The present invention is further described with reference to the accompanying drawings and detailed description.
Accompanying drawing 1 is the structural representation of the present invention,
Attached drawing 2 is unidirectional rubber valve structural schematic diagram of the invention.
In figure: 1, prick hoop, 11, knob, 2, bung, 21, on along side, 3, staving, 31, screw thread side, 32, lower along side, 33, peace
Fill hole, 4, polybag, 5, unidirectional rubber valve, 51, bonnet, 52, valve body, 521, valve chamber, 522, sealing, 523, section.
Specific embodiment
As shown in attached drawing 1 and attached drawing 2, a kind of plastic barrel of internal negative pressure self-balancing of the present invention includes pricking hoop 1, bung
2, staving 3, polybag 4 and unidirectional rubber valve 5.
The bundle hoop 1 is provided with knob 11；The bung 2 is provided with internal screw thread, and bung 2 is also provided with along side
21；The top of the staving 3 set gradually screw thread while 31 and it is lower along while 32, screw thread side 31 be provided with external screw thread, screw thread side
31 and lower mounting hole 33 is also provided between side 32；The polybag 4 is placed in staving 3, and the unidirectional rubber valve 5 is pacified
Loaded in mounting hole 33；The unidirectional rubber valve 5 includes bonnet 51 and valve body 52, and the right end of valve body 52 is provided with bonnet 51,
The valve chamber 521 of connection is provided in valve body 52 and in bonnet 51, valve body 52 is provided with the sealing of closure in the left side of valve chamber 521
522, the left end both sides of valve body 52 are provided with the section 523 for being parallel to sealing 522.
In use, feed liquid is injected in the polybag 4 in staving 3, cotton rope tightens the sack of polybag 4, and bung 2 passes through spiral shell
Line is attached with screw thread side 31, prick hoop 1 by the bung 2 of fitting along while 21 under staving 3 along while 32 11 tightened by shaking hands,
After the feed liquid temperature in polybag 4 declines, material liquid volume is shunk, the drop of pressure in staving 3, and the pressure in staving 3 is lower than
Pressure outside staving 3, sealing 522 opens under the action of internal and external pressure difference, and outside air enters in staving 3, until in staving 3
Outer pressure balance, sealing 522 are closed, and the situation for avoiding the drop of pressure in staving 3 that staving 3 is invaginated occurs.
The above, embodiment is only that preferred embodiments of the present invention will be described, not to of the invention
Range is defined, and under the premise of not departing from the spirit of the technology of the present invention, this field engineers and technicians are to skill of the invention
The various changes and improvements that art scheme is made, should fall within the scope of protection determined by the claims of the present invention.
