Abstract
The utility model relates to an explosion-proof pressure limiting bottle cap which is composed of the sealing ring of an outer cap and a pressure limiting valve. The utility model is characterized in that a small hole used for installing the pressure limiting valve is arranged on the outer cap, and the pressure limiting valve and the sealing ring are arranged on the small hole. The utility model which has the advantages of novel structure and easy manufacture has a pressure limiting protecting device. When air temperature rises and pressure in a bottle increases, the utility model can reduce pressure automatically to play the function of explosion prevention. The utility model can be used for the sealing and packing of pressurized bottles and beer bottles.
Description
The utility model relates to a kind of bottle cap, specifically a kind of pressure limiting explosion-proof bottle cap.
Present bottle cap mostly is not with explosion protection not have measures for the prevention of explosion, brings many inconvenience to the user, such as beer bottle, and the pop bottle blast of uncapping, damage human eye etc.
The purpose of this utility model is to provide a kind of pressure limiting explosion-proof bottle cap; there is protective arrangement for limiting output voltage to work as temperature rising pressure of the inside of a bottle when increasing on this bottle cap; can emit some gases automatically and not make pressure of the inside of a bottle excessive; foul is entered in the bottle; in order to overcome existing pop bottle, the deficiency of beer bottle cap.
The purpose of this utility model can realize by following proposal:
The utility model is made up of enclosing cover, seal ring and limiting valve.Enclosing cover is with now using carbonated drink, and beer bottle cap is the aperture that a peace limiting valve is arranged on it, is equipped with limiting valve and seal ring on the aperture.Annular roller clamp nut is arranged, hollow double-screw bolt, pressure limiting post, spring, type pressure pad and shell on the limiting valve.Hollow double-screw bolt appearance is the garden cylindricality, and fine thread is arranged on the outside face, and a hole is arranged in the middle of it, and this hole the higher authorities' diameter is thin, and following diameter is thick, the thick section dress of diameter pressure limiting post, spring and type pressure pad, and thin segment is given pressure limiting post location.The pressure limiting post is a nail-shaped, and a circle pit is arranged in the middle of the lower surface, supplies with type pressure pad location.The convex shape pressure pad is a ring shape, above in the middle of nipple projection is arranged for the location.Shell is a cylindrical shape, a little logical steam vent is arranged at the end, and screw thread is arranged on the outer casing inner wall, keeps supplying the hollow double-screw bolt.
The utility model has the advantages that novel structure, easy to manufacture, protective arrangement for limiting output voltage is arranged; when temperature rising pressure of the inside of a bottle increases, can emit the part gas automatically and keep safety flack to press, outside foul is entered in the bottle; can also guarantee the outside stressed of enclosing cover, be a kind of suitable explosion-proof bottle cap.This bottle cap can be used for pop bottle, the encapsulation of beer bottle.
Below in conjunction with accompanying drawing the utility model is done detailed description further.
