Description
Technical field
It the utility model is related to the manhole of pressure vessel in industrial production, specially a kind of opening soon with manual locking device
Manhole, suitable for the application of various Pressure container manholes.
Background technology
In modern scientific research and industrial production, when furtheing investigate certain inflammable, explosive medium, it is often necessary at some
Ignite the medium in closed high-potting tank, to understand its performance.And on test tank manhole quick opening and closing pair
The efficiency of experiment plays very important effect.But wirking pressure container manhole generally existing some shortcomings：Mostly flange
Form, screw is more, opening and closing inconvenience, wastes time and energy, it is often necessary to which more people complete jointly, directly reduce efficiency.Therefore,
A kind of manhole with quick-locking device is needed to meet the needs of research, production process, makes up conventional manhole's open and close inconvenience
The defects of.
The content of the invention
The utility model is slow in order to solve conventional manhole's opening and closing speed, and inconvenient, the problem of wasting time and energy, there is provided one
Self-tightening type quick opening manhole of the kind with quick-locking device.
The utility model is achieved by the following scheme：
A kind of self-tightening type quick opening manhole's structure with manual locking device, including the manhole cover positioned at device interior and fixation
In the manhole gate seat on apparatus casing, the manhole cover is connected by hinge with apparatus casing；It is uniformly solid on the manhole gate seat
Surely some fixed briquettings are arranged；The corresponding manual locking in, position identical with fixed briquetting quantity is installed on the manhole cover to fill
Put.
The manual locking device includes sleeve, and handle and secter pat are welded with the outside of the sleeve；The sleeve is placed on
On studs, described studs one end is threadedly coupled with manhole cover, and another end nut is tightened.
During closure state, the manhole cover is closed on manhole gate seat, is matched somebody with somebody between secter pat and fixed briquetting by inclined-plane
Close.
During concrete operations, traditional manhole cover is all disposed within the outside of equipment, and in the utility model, manhole cover is arranged at
Device interior, and pass through hinge and apparatus casing external connection；When manhole closes, manhole cover is closed on manhole gate seat；In order to
Make the two better seal, several have been evenly arranged on manhole gate seat and has fixed briquetting, while with fixing briquetting on manhole cover
Corresponding position bolt connection has the manual locking device of identical quantity.Manual locking device main body is sleeve, on the outside of sleeve
Handle and secter pat are welded, sleeve is placed on studs, and this studs one end is connected with manhole cover bolt hole, the other end
Tightened with nut.During rotary handle, in order that fixed briquetting is compressed with secter pat and coincide, fixed briquetting needs supporting with secter pat
Installation, ensure that secter pat fits like a glove with the fixation briquetting on manhole gate seat when manhole closes, therefore fixed briquetting upper surface
It is the inclined-plane coordinated with secter pat lower surface, during rotational handle, secter pat can be rotated further hand with fixed briquetting with tight connecting
Handle, manhole closure are tighter；When manhole cover to be opened, opposite direction rotary handle, secter pat is separated with briquetting, and manhole is opened.
Preferably, in order that manhole cover even running during open and close, by manhole cover and apparatus casing hinge
Connect as one, and hinge is arranged on device external, convenient maintenance, hinge includes 2 section connecting plates, and this 2 section connecting plate passes through
Pivot pin connects as one；With welding hanger on apparatus casing, connecting plate entirety one end is connected to by pivot pin in manhole cover center
Hanger on manhole cover, the other end are connected to the hanger on apparatus casing by pivot pin, such manhole cover just with apparatus casing
On the basis of connection, can steadily it switch, securely and reliably.
More sealed when preferably, in order to close, manhole cover and manhole gate seat can be used concavo-convex surface seal structure, not only
The stability of Manhole Sealing Joints when can play fixed manhole cover effect, while add closure.
More preferred, in order to increase the sealing property of manhole, some setting-up piece spiral shells are uniformly arranged on manhole cover
Silk hole, and compress gasket is installed by setting-up piece screw on manhole cover sealing surface, when closing manhole, manhole cover and manhole door
The identical compress gasket of seat, plays more preferably sealing function.
The good result that the utility model has is：Easy for installation, simple to operate, whole process, which only needs one, to be grasped
Make, rapid and convenient is compact-sized, securely and reliably, overcomes the opening and closing inconvenience of conventional manhole, takes the problem of manpower is more.
