The utility model is an improvement on the manhole of the pressure vessel, and provides an inwardly opened and built-in manhole. Its composition includes a cylinder section fixed to the container body, a flange cover connected to the cylinder section and a head connected to the flange, and the feature is that the said head is a A convex head that protrudes toward the inner cavity of the container, and a connecting flange that can be connected to the bottom of the flange on the barrel joint is fixedly connected to the port of the convex head. A sealing ring is provided and connected by bolts, and lifting lugs are also provided on the concave surface of the convex head. Can be used in various pressure vessels.

Description

Pressure container manhole
The utility model relates to a kind of manhole of pressure container.
The manufacturing of pressure container for convenience and make things convenient for the supervisory personnel to enter internal tank during use to carry out repair and maintenance, pressure container is equipped with manhole.Existing Pressure container manhole is the external-open external, for example JB584-79 " level is hung and covered manhole with butt welded flange " and JB585-79 " level is hung and covered manhole with butt welded flange ".The less than one of the external-open external manhole of this routine is that not only the force status of self is poor because the flat cover flange is the dull and stereotyped pressure parts that is subjected to internal pressure, and it will all bear by binding bolt with joint efforts, easily causes sealing face leakage; The 2nd, its flat cover flange is the pie forging, difficult quality guarantee; The 3rd, when being used to transport the formula tank car, exposing of the manhole of evagination highly causes it bulky, has influence on the crossing ability of tank car; When being used for the insulation of low temperature tank car (as the liquid CO 2 tank car) needs, also can be restricted to the value of adiabatic layer thickness, make heat-insulating property be difficult for reaching.
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing manhole, provide a kind of good sealing effect, the easier assurance of quality in open built-in manhole.
Realize the utility model purpose in open built-in manhole formation comprise that the shell ring that is fixed in vessel and lid are connected to the flange on the shell ring and are connected end socket on this flange, described end socket is a convex end socket to container body inner chamber projection that is arranged in the shell ring, on the port of described convex end socket, be connected with a mounting flange below the flange that can be connected on the shell ring, be provided with seal ring between two flanges, bolt together also is provided with hanger on the concave surface of described convex end socket.The convex formula end socket that is located in the shell ring is reduced its outside dimension, the also more original flat end socket of the force status of convex end socket makes moderate progress, suffered pressure is external pressure, and all the flange by port is used for the pinch-off seal circle and helps strengthening sealing property.Be located at when hanger on the convex end socket concave surface then is used for dismounting and manhole is installed and use.
Compared with prior art, the utlity model has following advantage:
1), end socket self force-bearing situation is improved, and pressure is external pressure and all is used for the pinch-off seal circle, improved the leak free reliability;
2), two butt flanges of the present utility model are the ring-type forging, easier the ensuring the quality of products of flat cover capping of more existing pie forging;
3), expose highly greatly to reduce its oad reduced, help improving the crossing ability of transportation formula tank car;
4), since whole manhole be installed in the container body, whole manhole is embedded in the heat-insulation layer, its heat insulation effect is improved.
Provide embodiment below in conjunction with accompanying drawing.
Fig. 1 structural representation of the present utility model
As shown in the figure, shell ring 1 is fixed on the vessel 2, and flange 5 is welded on the shell ring 1, and convex end socket 13 is located in the shell ring 1 and to convex, and annular flange dish 4 is welded on the port of convex end socket 13, is positioned at the below of flange 5.Seal ring 6 is located between two flanges, and two flanges connect with bolt 7, and hanger 10 is fixed on the concave surface of convex end socket 13.
Be dismounting and the installation that makes things convenient for the convex end socket, two ringbolts 12 can be set on flange 5, and between ringbolt 12 and hanger, be provided with and be connected hauling rope 11.Index rope 11 can be selected nylon rope for use.Slowly descend or lifting convex end socket 13 when this nylon rope then can and be installed manhole in dismounting by handling.

Claims (2)

1, a kind of Pressure container manhole, comprise that the shell ring that is fixed in vessel and lid are connected to the flange on the shell ring and are connected end socket on this flange, it is characterized in that described end socket is a convex end socket to container body inner chamber projection that is arranged in the shell ring, on the port of described convex end socket, be connected with a mounting flange below the flange that can be connected on the shell ring, be provided with seal ring between two flanges, bolt together also is provided with hanger on the concave surface of described convex end socket.
2, Pressure container manhole as claimed in claim 1 is characterized in that also being provided with ringbolt on the flange on the described shell ring, be provided with to be connected hauling rope between ringbolt and hanger.
