Abstract
The utility model discloses an anti-expansion and anti-contraction packing barrel cover which is simple in structure, convenient to clean and maintain, safe and reliable. The anti-expansion and anti-contraction packing barrel cover is used for filling liquid. The anti-expansion and anti-contraction packing barrel cover comprises a barrel cover body. The barrel cover body is provided with a concave platform. Two holes are formed in the concave platform. The two holes are respectively and fixedly connected with a first breather pipe and a second breather pipe, wherein the first breather pipe opens upwards, and a venthole is formed on one side of the lower portion of the first breather pipe. A thermoplasticity elastic tube is sleeved outside the venthole. The thermoplasticity elastic tube of the first breather pipe is placed inside the barrel cover body. The second breather pipe opens downwards. A venthole is formed on the upper portion of the second breather pipe. A thermoplasticity elastic tube is sleeved outside the venthole, and the end of the thermoplasticity elastic tube of the second breather pipe is placed on the outer portion of the barrel cover body.
Description
Technical field
The utility model relates to a kind of Packing bucket bung, relates in particular to a kind of anti expanding and shrinking Packing bucket bung.
Background technology
Existing liquid package container for preventing leak of liquid, generally adopts outer bung screw socket to cooperate the inner cap sealing means in transportation, storing process.Be in the positive confinement state owing to inside and outside the container in the routine use, produce internal tank formation malleation or the negative pressure that biochemical reaction causes in case variation of ambient temperature or in-built liquid occur from body, be easy to cause container to expand, shrinkage distortion is impaired or blast, causes safety misadventure and economic loss.
At present, solve the expansion of said vesse container, contraction problem, main spring metal safety valve and two kinds of intake and exhaust forms of ventilated membrane of adopting, liquid in container enters in safety valve or the ventilated membrane in the transportation but all exist, cause the obstruction difficult in maintenance, easy of its cleaning parts, poor stability, also have the problems such as component structural is complicated, cost is higher, and use is inconvenient.
Summary of the invention
The purpose of this utility model provides the convenient and safe and reliable anti expanding and shrinking Packing bucket bung of a kind of simple in structure, clean and maintenance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti expanding and shrinking Packing bucket bung, comprise the bung body, it is characterized in that: be designed with the indent platform on the bung body, have two holes on the indent platform, be fixedly connected with respectively the first breather pipe and the second breather pipe in two holes, the first breather pipe upward opening, one side of the first breather pipe bottom has air extractor vent, the air extractor vent overcoat has resilient thermoplastic tube, the resilient thermoplastic tube of the first breather pipe is positioned at the bung body, the second breather pipe is under shed, the top of the second breather pipe has air extractor vent, and the air extractor vent overcoat has resilient thermoplastic tube, and the thermoplastic elastic pipe end of the second breather pipe is positioned at the bung body exterior.
In this structure, the inside face of bung body is designed to the self sealss inclined-plane.
In this structure, the outside face of bung body is designed with reinforced rib.
The utility model has the advantages of and be: because this structure of the present utility model, the first breather pipe and the second breather pipe are unenclosed construction, direct water flushing can reach cleaning purpose during cycling and reutilization, tpr resilient thermoplastic tube aboundresources, cheap, can change at any time, operate very simple, clean and maintenance is convenient, tpr thermoplastic elastic tubular elastic is high, and two way seal is functional, this material safety non-toxic, withstanding corrosion, use safely and economical and practical, self sealss inclined-plane, sealing effectiveness are better than inner cap sealing, save traditional bung and also needed to configure in addition the step that inner cap could seal, solved inner cap poorly sealed, the problem that use procedure is easily lost, easy and simple to handle, reduced again productive costs simultaneously, bidirectional pressure regulating is highly sensitive, and the self sealss performance is good.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
In the accompanying drawing: 1, indent platform; 2, bung body; 3, the second breather pipe; 4, the first breather pipe; 5, resilient thermoplastic tube; 6, reinforced rib; 7, self sealss inclined-plane; 8, air extractor vent.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model such as Fig. 1, shown in 2, a kind of anti expanding and shrinking Packing bucket bung, comprise bung body 2, it is characterized in that: be designed with indent platform 1 on the bung body 2, have two holes on the indent platform 1, be fixedly connected with respectively the first breather pipe 4 and the second breather pipe 3 in two holes, the first breather pipe 4 upward openings, one side of the first breather pipe 4 bottoms has air extractor vent 8, air extractor vent 8 overcoats have resilient thermoplastic tube 5, the resilient thermoplastic tube 5 of the first breather pipe is positioned at bung body 2, the second breather pipe 3 is under shed, the top of the second breather pipe 3 has air extractor vent 8, and air extractor vent 8 overcoats have resilient thermoplastic tube 5 ends of resilient thermoplastic tube 5, the second breather pipes to be positioned at bung body 2 outsides; In the present embodiment, the inside face of bung body 2 is designed to self sealss inclined-plane 7; In the present embodiment, the outside face of bung body 2 is designed with reinforced rib 6.
The anti expanding and shrinking Packing bucket bung adopts industry or food grade plastic or composite to make, outward appearance circle or polygon design, the centre of bung is designed with circular indent platform, Central Symmetry is installed two breather pipes on the indent platform, breather pipe adopts metal alloy or plastic material to make, breather pipe and indent platform adopt and cementingly are connected or are threaded, breather pipe one end is the nature opening, the other end is the blind mouth structure of sealing, open an aperture near a blind mouthful of end side surface, two breather pipes just are being connected with indent platform one anti-, keep the container inner air and outer air to communicate, and be nested with tpr resilient thermoplastic tube or other elastomeric material, seal relative with the container inner air and outer air at two breather pipes near air extractor vent one end respectively.
When container inner pressure was lower than the container external pressure, air entered by the opening on the first breather pipe on the bung body, utilized tpr resilient thermoplastic tube compressive strain characteristic to suck container through the air extractor vent of the first breather pipe, improved container inner pressure.When container inner pressure is higher than the container external pressure, air utilizes tpr resilient thermoplastic tube compressive strain characteristic amount discharge container by the air extractor vent of opening on the second breather pipe of the second breather pipe on the body in the bung, reduce container inner pressure, realize automatically regulating container inner pressure and extraneous balance, prevent container because expanding or shrinking product design and the potential safety hazard that causes, reached the effect of energy-saving safe, simple and effective.
Bung negative thread one end and bung contact position also are designed with a circle self sealss inclined-plane, and the self sealss inclined-plane is 45 ℃ of angles with the bung plane and contacts.When the rotation of bung body negative thread and bung outside thread was tightened, self sealss inclined-plane and bung were the state of closely cooperating in the bung body, have played good sealing effectiveness.
Bung negative thread opposite periphery also is designed with symmetrical reinforced rib, has improved the screwing force of bung, has increased intensity, and structure rationally, and is durable.
