Abstract
The utility model discloses a bottle opening of a plastic inner liner full-winding gas bottle for containing gas or gas and liquid mixed bodies with no corrosion effect on a plastic inner liner and a metal bottle nozzle and with the pressure being 1 to 100 MPa, which relates to a liquefied petroleum storage bottle. The bottle opening of the plastic inner liner full-winding gas bottle comprises a valve seat, wherein a fastening flange and a locking ring are arranged outside the valve seat, and the locking ring is buckled above the fastening flange. The metal flange sealing principle is adopted, through the unique forming process, an inner liner opening is used as a sealing base surface, a sealing pad is used as a sealing medium, the metal valve seat is used as a sealed stress substrate, and the problem of connection reliability of plastics and metal and the problem of sealing performance caused by the connection reliability are solved through the rated sealing force exerted by the fastening flange, so the gas bottle has good gas tightness.
Description
Technical field
The utility model relates to a kind of holding bottle of liquefied petroleum, relates in particular to the bottleneck of the full winding gas cylinder of plastics inner bag of a kind of splendid attire is free from corrosion to plastics inner bag and metal bottle neck, pressure is 1～100MPa gas or gas liquid mixture.
Background technique
Excellent properties such as the full winding gas cylinder of plastics inner bag is in light weight with it, intensity is high, corrosion-resistant have broad prospects in order to substitute traditional metal gas cylinder.But be subjected to the restriction of plastics self intensity, the air outlet of plastics inner bag gas cylinder is made by metallic material usually, because the modulus and the rates of thermal expansion of two kinds of materials differ greatly, and make the binding site of two kinds of materials can occur the crack because of rigidity is discontinuous when suffering cyclic loading; Under the effect of ambient temperature, can produce thermal stress, also can make the connecting part crackle occur, thereby cause gas cylinder gas leakage.
At this problem, many improved technology appear both at home and abroad.Bending of the space flight forth academy waited the people to propose the structure shown in the ZL97103911.9 forever by force in 1997, and metal bottle neck and plastics is one-body molded by rotational moulding, adopted area of contact that increases metal bottle neck and plastics inner bag and the method for colluding with intensity to improve sealability.Congratulate few fine jade in 1999 and proposed the structure shown in the ZL99230746.3, adopt so-called mazy type packing ring and special cylinder valve to improve the sealability of gas cylinder.People such as Wang Yupu had proposed the structure shown in the ZL200620120643.1 in 2006, this structure is comparatively complicated, utilize the fixing broadside flange of screw thread on the plastics bottle neck, be the sealing basal plane with flange bottom surface, narrow limit, broadside flange top again, outward flange with the valve seat bottom is the force side, do medium with seal ring, sealing between plastics and the metal is converted into sealing between metal and the metal, thereby improve the sealability of gas cylinder.Abroad, the production of plastics inner bag gas cylinder mainly concentrates on American-European countries, and different is the inner bag employing injection moulding or the compression molding of metal bottle neck end, is combined to form inner bag with welding method again, as the Ragasco company of Norway, and U.S. lincoln company.
The sealing force that these structures all exist between plastics inner bag and the metal bottle neck is the power that forms naturally by in the moulding, is difficult to control, often causes sealing reliability not enough, is easy to generate leakage.Complex technical process has reduced manufacturing efficiency simultaneously.
Summary of the invention
The utility model is not enough at bottleneck sealing reliability in the prior art, is easy to generate the deficiency of the deficiency of leakage, and the bottleneck of the full winding gas cylinder of a kind of plastics inner bag is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The bottleneck of the full winding gas cylinder of plastics inner bag, bottleneck comprises valve seat, and the valve seat outside is provided with clamp flange and locking ring, and locking ring is buckled in the clamp flange top.Adopt the metal flange sealing principle, moulding process by uniqueness, with the inner-tube mouth is the sealing basal plane, sealing gasket is a sealing medium, metal seat valve is the stressed matrix of sealing, apply specified sealing force by clamp flange and solved integrity problem that plastics are connected with metal and the sealing problem that brings thus, make the gas cylinder have good air-tightness.
As preferably, valve seat comprises valve seat cylindrical shell and annular flange.Metal seat valve cylindrical shell and annular flange are one-body molded, and the annular flange of column cylindrical body and bottom is that the fillet of 2～5mm links to each other by radius.
As preferably, the edge of annular flange is provided with the rim of the mouth.Rim of the mouth width 1～3mm, the degree of depth 1～4mm.The rim of the mouth at the annular flange edge of inner core inserted valve seat bottom.The effect in rim of the mouth is that metal seat valve drops after preventing the inner bag moulding, limits the transverse movement of metal seat valve simultaneously, allows it axially doing finite movement (1～2mm).
As preferably, the valve seat cylinder inboard wall is provided with internal thread, and outer wall is provided with outside thread.Be convenient to be connected with miscellaneous part.
As preferably, a cyclic convex edge is arranged at locking ring top, and a planar annular is arranged at the bottom; The outer wall of locking ring is smooth, and inwall has screw thread.Locking ring is located at the top of clamp flange, prevents that clamp flange is loosening.Cyclic convex edge is convenient to be installed, and people also are convenient to rotation when in use.
According to the technical solution of the utility model, the sealing height of bottle mouth of gas cylinder, bottleneck are difficult for producing leakage.
