Abstract
The utility model discloses a kind of pressure pan, including：Cylinder, an end flange is welded with the upper port of cylinder, a top cover is covered with end flange, the charging aperture being connected with cylinder is provided with top cover, a ball sealing head for energy closed cylinder lower port is welded with the lower port of cylinder, wall thickness of the wall thickness of ball sealing head less than cylinder, the bottom of ball sealing head is provided with discharging opening, the annular Reinforced Hoop that a circle can overcome the disadvantages that ball sealing head and the cylinder wall thickness difference of ball sealing head and cylinder joint, the lateral wall of annular Reinforced Hoop and the lateral wall consistency from top to bottom of cylinder are welded with the outside of ball sealing head end mouthful.A kind of above-mentioned pressure pan it is simple and reliable for structure, and due to having welded a ring shape Reinforced Hoop on the outside of the port of ball sealing head, so as to make up the ball sealing head of ball sealing head and cylinder joint and the Wall-Thickness Difference of cylinder well, the internal stress at butt weld can thus be greatly reduced and can be uniformly distributed internal stress, substantially increase the service life of pressure pan.
Description
Technical field
The utility model is related to high-tension apparatus field, and in particular to a kind of pressure pan.
Background technology
Pressure pan is a kind of pressure vessel, and the structure of conventional high-pressure tank includes：Cylinder, is welded with the upper port of cylinder
One end flange, is covered with a top cover in end flange, and the charging aperture being connected with cylinder is provided with top cover,
A ball sealing head for energy closed cylinder lower port is welded with the lower port of cylinder, the bottom of ball sealing head is provided with discharging opening,
Because technique needs, the wall thickness of ball sealing head will usually be less than the wall thickness of cylinder.Because the wall thickness and cylinder wall thickness of ball sealing head differ
Cause, so the internal stress at the butt welding of ball sealing head and cylinder can compare concentration, so that joint is easy for producing fracture,
The service life of pressure pan can thus be greatly shortened.Ball sealing head would generally be made using cylinder chamfered edge and the method for end socket built-up welding
Wall thickness with cylinder joint is consistent, and cylinder chamfered edge refers to：Side wall at cylinder lower port is cut so that cylinder lower end
Cylinder wall thickness at mouthful are consistent with ball sealing head wall thickness；End socket built-up welding refers to：In ball sealing head and the ball sealing rostral wall of cylinder joint
On carry out built-up welding so that the wall thickness of ball sealing head port is consistent with the wall thickness of cylinder；But cylinder chamfered edge can cause material
Utilization rate declines；And end socket built-up welding easily produces weld defect at built-up welding and jeopardizes mother metal, while when the thickness of built-up welding is big
The stress of weld can also be greatly increased, so as to be easily caused joint deformation.
Utility model content
Technical problem to be solved in the utility model is：To provide it is a kind of it is simple and reliable for structure, can overcome the disadvantages that ball sealing head and
A kind of ball sealing head of the cylinder joint pressure pan poor with cylinder wall thickness.
In order to solve the above problems, the technical solution adopted in the utility model is：A kind of pressure pan, including：Cylinder, in cylinder
An end flange is welded with the upper port of body, a top cover is covered with end flange, be provided with top cover and cylinder
The charging aperture of body phase connection, is welded with a ball sealing head for energy closed cylinder lower port in the lower port of cylinder, ball sealing head
Wall thickness is provided with discharging opening less than the wall thickness of cylinder in the bottom of ball sealing head, is characterized in：It is welded with the outside of ball sealing head end mouthful
One circle can overcome the disadvantages that the annular Reinforced Hoop of ball sealing head and the cylinder wall thickness difference of ball sealing head and cylinder joint, the outside of annular Reinforced Hoop
The lateral wall consistency from top to bottom of wall and cylinder.
Further, foregoing a kind of pressure pan, wherein：Offering several on the side wall of annular Reinforced Hoop can discharge
The steam vent of the gas that annular Reinforced Hoop and ball sealing head are produced when welding.
Further, foregoing a kind of pressure pan, wherein：A circle level is provided with the lower surface of annular Reinforced Hoop to put down
Face.
Advantage of the present utility model is：A kind of pressure pan described in the utility model it is simple and reliable for structure, and due to
A ring shape Reinforced Hoop is welded on the outside of the port of ball sealing head, so as to make up the ball of ball sealing head and cylinder joint well
End socket and the Wall-Thickness Difference of cylinder, can thus greatly reduce the internal stress at butt weld and can be uniformly distributed internal stress, greatly
The big service life that improve pressure pan.
Brief description of the drawings
Fig. 1 is a kind of structural representation of pressure pan described in the utility model.
Specific embodiment
The utility model is described in further detail with reference to specific embodiments and the drawings.
As shown in figure 1, a kind of pressure pan, including：Cylinder 1, is welded with an end flange 2 in the upper port of cylinder 1,
A top cover 3 is covered with end flange 2, the charging aperture 31 being connected with cylinder 1 is provided with top cover 3, in cylinder 1
A ball sealing first 4 for the energy lower port of closed cylinder 1 is welded with lower port, the wall thickness of ball sealing first 4 is less than the wall thickness of cylinder 1,
The bottom of ball sealing first 4 is provided with discharging opening 41, a circle is welded with the outside of first 4 port of ball sealing and can overcome the disadvantages that ball sealing first 4 and cylinder 1 pair
The ball sealing first 4 at place and the annular Reinforced Hoop 5 of the Wall-Thickness Difference of cylinder 1 are connect, on the lateral wall of annular Reinforced Hoop 5 and the lateral wall of cylinder 1
Lower alignment.Annular Reinforced Hoop 5 can make ball sealing first 4 identical with the wall thickness of the joint of cylinder 1, so as to greatly reduce at butt weld
Internal stress and can be uniformly distributed internal stress.In the present embodiment, several energy are offered on the side wall of annular Reinforced Hoop 5
The steam vent 51 of the gas that the annular Reinforced Hoop 5 of discharge and ball sealing first 4 are produced when welding, steam vent 51 can make the He of annular Reinforced Hoop 5
It is more firm that ball sealing first 4 is welded.In addition, being provided with a circle horizontal plane on the lower surface of annular Reinforced Hoop 5, so setting is
In order that pressure pan reliably can fall to being seated in support platform 6 by annular Reinforced Hoop 5.
