Technical Field
The utility model relates to the technical field of flanges, in particular to a flange for a pressure container.
Background
Pressure vessels are the most widely used equipment in the petrochemical industry and are one of the major production tools in the petrochemical industry. Because of the process requirements and the requirements for installing equipment internals, the pressure vessel often needs to be provided with a flange, which is more applicable to: the flange is specially used for industries such as heating and ventilating power building water supply pressure vessel fittings, pressure pipeline fittings and the like. The pressure vessel flange needs to have strong connection performance and pressure resistance. Most of the existing pressure vessel flanges are insufficient in connection performance, and fatigue damage is easily caused under long-term working pressure, so that the service life is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a flange for a pressure container, which can improve the connection strength between flanges.
In order to achieve the purpose of the utility model, a flange for a pressure container is provided, which comprises a first flange and a second flange,
a plurality of connecting blocks are annularly arranged on the connecting surface of the first flange; a fixed block is fixed on the connecting block; the fixing block is a trapezoidal block, and the side surface of the fixing block is arc-shaped; a plurality of connecting grooves are formed in the connecting surface of the second flange at positions matched with the fixing blocks; limiting holes are formed in two sides in the connecting groove; a limiting block is connected in the limiting hole in a sliding manner, wherein one part of the limiting block is arranged on the outer side of the limiting hole; the limiting block is far away from one side of the connecting groove and a limiting spring is connected between the limiting holes.
Preferably, a boss is annularly arranged on one side of the connecting surface of the second flange; the arc surface of the boss is provided with an external thread; and the boss is provided with a sealing sheet.
Preferably, the longitudinal section of the limiting block is trapezoidal.
Preferably, the number of the connecting blocks and the fixing blocks is four.
The working principle is as follows: the utility model provides a flange for pressure vessel, when first flange and second flange installation, passes through threaded connection with the gasket earlier, installs in second flange one side, later promotes first flange, and during connecting block and fixed block got into the spread groove, the fixed block promoted the stopper and inwards removes, and after first flange hugged closely the gasket, the stopper popped out, the chucking fixed block.
Compared with the prior art, the flange for the pressure container has the following advantages that:
(1) the fixing block is clamped tightly by the limiting block, so that the connecting strength of the first flange and the second flange is improved;
(2) the fixed block is a trapezoidal block, so that a limiting block is conveniently pushed, and the connecting speed of the first flange and the second flange is increased;
(3) the design is simple, easy to use, and low in manufacturing cost.

Detailed Description
The utility model is further described below with reference to the following figures and specific examples.
As shown in fig. 1 to 6, a flange for a pressure vessel, comprising a first flange 1 and a second flange 2,
a plurality of connecting blocks 11 are annularly arranged on the connecting surface of the first flange 1; a fixed block 12 is fixed on the connecting block 11; the fixed block 12 is a trapezoidal block, and the side surface of the fixed block 12 is arc-shaped; a plurality of connecting grooves 21 are arranged on the connecting surface of the second flange 2 at positions matched with the fixing blocks 12; both sides in the connecting groove 21 are provided with limiting holes 22; a limiting block 23 is slidably connected in the limiting hole 22, wherein a part of the limiting block 23 is arranged outside the limiting hole 22; the stopper 23 is kept away from spread groove 21 one side with be connected with spacing spring 24 between the spacing hole 22, make stopper 23 remove in spacing hole 22 through spacing spring 24, fixed block 12 inserts in spread groove 21, because fixed block 12 is the trapezoidal piece, the top of fixed block 12 gets into back between the stopper 23, fixed block 12 promotes stopper 23 and inwards removes, spacing spring 24 contracts, fixed block 12 gets into the back, stopper 23 stretches out through spacing spring 24, it is fixed with fixed block 12 and first flange 1, prevent that position deviation from appearing in two flanges, increase the intensity of being connected between first flange 1 and the second flange 2.
In this embodiment, a boss 25 is annularly arranged on one side of the connecting surface of the second flange 2; be equipped with external screw thread 251 on the arc surface of boss 25, be equipped with gasket 3 on the boss 25, make gasket 3 and second flange 2 be connected through external screw thread 251, make things convenient for the fixed of gasket 3, wherein set up the hole that connecting block 11 and fixed block 12 passed on the gasket 3, rotate gasket 3 through external screw thread 251, make things convenient for the hole on the gasket 3 corresponding with spread groove 21.
In this embodiment, the longitudinal section of the limiting block 23 is trapezoidal, so that the limiting block 23 can be conveniently pushed by the fixing block 12.
In this embodiment, the number of the connecting blocks 11 and the fixing blocks 12 is four, and the four groups of connecting blocks 11 and fixing blocks 12 are clamped in the connecting grooves 21, so that the connecting strength between the two flanges is improved, and the cost is reduced without arranging too many connecting blocks 11 and fixing blocks 12.
When first flange 1 and the installation of second flange 2, pass through threaded connection with the gasket 3 earlier, install in second flange 2 one side, later promote first flange 1, during connecting block 11 and fixed block 12 got into spread groove 21, fixed block 12 promoted stopper 23 inward movement, first flange 1 pastes tight gasket 3 back, stopper 23 pops out, chucking fixed block 12, conveniently assembles fixedly first flange 1 and second flange 2, has improved the intensity of connecting between the flange.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the utility model is not limited to the embodiments disclosed, but is capable of various modifications and substitutions without departing from the spirit of the utility model.
