Description

Technical Field

[0001] This invention relates to pressure vessels, specifically a pressure vessel resistant to high pressure. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Its applications are extremely wide-ranging, playing a vital role in many sectors of industry, civil use, military industry, and scientific research. In the chemical and petrochemical industries, pressure vessels are mainly used for heat transfer, mass transfer, and reaction processes, as well as for storing and transporting pressurized gases or liquefied gases. They also have wide applications in other industrial and civil fields, such as air compressors. Various specialized compressors and auxiliary equipment for refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid refrigerant storage tanks, etc.) all belong to pressure vessels. The pressure resistance of a pressure vessel is closely related to its sealing performance and the vessel itself. The thicker the tank wall, the better the pressure resistance; however, thicker walls also increase the cost of materials used in vessel production and raise the technical requirements for welding. Furthermore, leakage points in pressure vessels mainly concentrate on issues such as the connection gap between the cover and the tank body. Therefore, this invention addresses and improves upon the above-mentioned and existing technical problems. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention provides a pressure vessel resistant to high pressure, which can effectively solve the problems existing in the prior art.

[0004] The technical solution of this invention is:

[0005] A pressure vessel resistant to high pressure includes a tank body and a cover body, with corresponding flanges and rubber rings provided between the tank body and the cover body; a discharge port is provided at the lowest end of the tank body; reinforcing ribs are provided at equal intervals on the outer side wall of the tank body, and the reinforcing ribs extend upward from the discharge port to a position of 2 / 3 of the tank body length; a reinforcing strip is fixedly connected to the outer side wall of the cover body, staggered from the reinforcing ribs, and the reinforcing strip extends downward from the top of the cover body to a position of 2 / 3 of the tank body length; corresponding embedding grooves are provided at the same height above and below the overlapping portions of the reinforcing ribs and reinforcing strips; a fixing mechanism is provided on the side of the tank body to cooperate with the embedding grooves, and the fixing mechanism includes a semi-circular arm assembly positioned at the same height as the embedding grooves; the semi-circular arm assembly includes two hinged semi-circular arms, and a positioning plate is fixedly connected between the unhinged ends of the upper and lower semi-circular arms on the same side, and the positioning plate is provided with bolt holes.

[0006] The embedding groove is a right-angled trapezoidal structure that is narrower on the inside and wider on the outside.

[0007] The longitudinal section of the semicircular arm is a right-angled trapezoidal structure.

[0008] Advantages of this invention:

[0009] Without increasing the thickness of the tank wall, this invention enhances stability and improves the pressure vessel's resistance by adding reinforcing ribs, reinforcing strips, and semi-circular arms through their interaction and cooperation. Furthermore, it simplifies the sealing structure of the sealing cover to ensure airtightness and optimizes its convenience and ease of use. Attached Figure Description

[0012] Figure 3 This is a schematic diagram of the tank's structure. Detailed Implementation

[0013] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings:

[0014] refer to Figure 1-3 A pressure vessel resistant to high pressure includes a tank body 1 and a cover body 2, with corresponding flanges and rubber rings 3 provided between the tank body 1 and the cover body 2; a discharge port (unmarked) is provided at the lowest end of the tank body 1; reinforcing ribs 4 are provided at equal intervals on the outer side wall of the tank body 1, and the reinforcing ribs 4 extend upward from the discharge port to a position of 2 / 3 of the tank body length; a reinforcing strip 5 is fixedly connected to the outer side wall of the cover body 2, which is staggered from the reinforcing ribs 4, and the reinforcing strip 5 extends downward from the top of the cover body 2 to a position of 2 / 3 of the tank body length; the reinforcing ribs 4 and the reinforcing strip 5 are provided at equal intervals on the outer side wall of the cover body 2 ... extend downward from the top of the cover body 2 to a position of 2 / 3 of the tank body length; the reinforcing ribs 4 and the reinforcing strip 5 extend downward from the top of the cover body 2 to a position of 2 / 3 of the tank body length; the reinforcing ribs 4 and the reinforcing strip 5 extend downward from the top of the cover body 2 to The overlapping portions of strip 5 are provided with corresponding embedding grooves 6 at the same height. The embedding groove 6 is a right-angled trapezoidal structure that is narrower inside and wider outside, with the hypotenuse facing downwards. The side of the tank body 1 is provided with a fixing mechanism that cooperates with the embedding groove 6. The fixing mechanism includes a semi-circular arm group 8 that is positioned at the same height as the embedding groove 6. The semi-circular arm group 8 includes two semi-circular arms 7 that are hinged and have a right-angled trapezoidal cross section. The unhinged ends of the semi-circular arms 7, which are positioned on the same side and are located vertically, are fixedly connected to a positioning plate 9. The positioning plate 9 is provided with bolt holes 10.

[0015] After the cover 2 is placed on top of the tank body 1, the reinforcing ribs 4 and reinforcing strips 5 are staggered. Two annular grooves are formed by the embedding grooves 6 on the reinforcing ribs 4 and reinforcing strips 5. The hinged semi-circular arm 7 is rotated to coincide with the positioning plate 9, and the two positioning plates 9 are locked together by bolts. The semi-circular arm 7 is engaged in the embedding groove 6. Due to the direct trapezoidal structure of the embedding groove 6, which is narrow inside and wide outside, and with the inclined side facing downward, a downward force is generated when the semi-circular arm 7 is engaged in the embedding groove 6. This forces the cover 2, which is connected to the reinforcing strip 5, downward to position and seal the cover 2, thereby enhancing the sealing performance.

[0016] The present invention does not require increasing the wall thickness of the tank body 1. The strength and pressure resistance of the tank body 1 are increased by uniformly distributing reinforcing ribs 4 on the outer side of the tank body 1. Moreover, the welding process, welding technology requirements and raw material costs of the welded reinforcing ribs 4 are lower than those of increasing the wall thickness.

[0017] Furthermore, the reinforcing strip 5 on the cover 2 strengthens and stabilizes the entire tank body 1, improving its durability. The reinforcing strip 5 and reinforcing rib 4 are uniformly fixed by the semi-circular arm 7 of the fixing mechanism. The reinforcing rib 4, in conjunction with the reinforcing strip 5, fixes the cover 2, improving the stability and sealing of the cover 2. While fixing the reinforcing strip 5 and the cover 2, the semi-circular arm 7 also strengthens the tank body 1 from a direction different from that of the reinforcing rib 4 and reinforcing strip 5. The embedded grooves 6 of the reinforcing strip 5 and reinforcing rib 4 also limit the movement of the semi-circular arm 7. The bolt connection direction of the positioning plate 9 on the semi-circular arm 7 is perpendicular to the direction of the cover 2, ensuring the sealing of the cover 2. This design is more convenient and simpler than the traditional structure with multiple sealing mechanisms on the cover 2. The reinforcing strip 5, reinforcing rib 4, and semi-circular arm 7 of this invention interact and restrain each other, improving the durability of the pressure vessel without increasing the wall thickness.

[0018] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
