Technical field
The utility model patent relates to a kind of pressurized container, particularly relates to a kind of High Pressure Fast Open manhole device.
Background technique
Pressurized container is very extensive in the application of petrochemical industry, and it realizes whole sealing for pressure vessels by the sealing between manhole cover and manhole.In traditional manhole structure, manhole cover is positioned at pressurized container outside, and pressurized container internal pressure is all born by manhole cover and manhole cover clamping bolt, and pressure is larger, manhole cover and clamping bolt size larger.Thus, in the opening and closing process of conventional high-tension Pressure container manhole lid, the dismounting of the moving of manhole cover, bolt and fasteningly about need 0.5 ~ 1 hour, takies the plenty of time, and operation effort.
Summary of the invention
The purpose of this utility model is that providing a kind of opens and closes time saving and energy saving high pressure vessel quick opening manhole device.
For this reason, the technical solution of the utility model is as follows:
A kind of High Pressure Fast Open manhole device, comprise shell ring and manhole cover, the bottom of described shell ring is stretched in manhole, and the bottom of shell ring radially extends to form the mounting platform of an annular to central direction, described mounting platform is arranged at intervals with multiple mounting hole to central direction opening; The ring wall surface that described manhole cover comprises base plate and upwards extends to form along base plate surrounding, the sectional shape of described ring wall surface and described shell ring adapts; On described base plate, along the circumferential direction interval is provided with and multiplely opens bolt soon with base plate by pinned connection, and described manhole cover and shell ring, through after corresponding described mounting hole, are tightened together by wing nut by described bolt of opening soon; The bottom of described manhole cover is provided with roller, is provided with guide rail below manhole cover, and described roller can roll along described guide rail.
Preferably, the length of described guide rail is no more than 2 times of location, bearing pin place diameter of a circle, after falling and allly opening bolt soon, opened by manhole cover, can be pulled out by manhole cover easily.
The described length opening bolt soon should be less than location, bearing pin place radius of a circle, to fall opening bolt soon after on manhole cover base plate, each bolt of opening soon can not be interfered mutually.
Between the ring wall surface and described shell ring of described manhole cover, seal arrangement is installed.Described seal arrangement can be O RunddichtringO.
Preferably, the ring wall surface of described manhole cover is formed with seal groove, described seal arrangement is metal loop seals and is arranged in described seal groove.
The utility model patent has following beneficial effect:
1, manhole cover is placed in pressurized container inside by this structure, utilizes pressurized container internal pressure to realize self-powering type sealing;
2, bolt Quick fastening and dismounting is achieved by opening bolt soon;
3, reduce clamping bolt size, achieved the slip of manhole cover by guide rail and roller, thus can fast opening and closing manhole cover.

Embodiment
Be described in detail below in conjunction with the structure of accompanying drawing to High Pressure Fast Open manhole device of the present utility model.
See Fig. 1 ~ Fig. 3, High Pressure Fast Open manhole device of the present utility model comprises: shell ring 5 and manhole cover 3.The bottom of shell ring 5 is stretched in manhole, and the bottom of shell ring 5 radially extends to form the mounting platform 10 of an annular to central direction, mounting platform 10 is arranged at intervals with multiple mounting hole to central direction opening.
The ring wall surface that described manhole cover 3 comprises base plate and upwards extends to form along base plate surrounding, the sectional shape of described ring wall surface and described shell ring 5 adapts; On described base plate, along the circumferential direction interval be provided with multiple be connected by bearing pin 9 with base plate open bolt 6 soon.Described manhole cover 2 and shell ring 5, through after corresponding mounting hole, are tightened together by wing nut 7 by each bolt 6 of opening soon.In addition, be also provided with roller 8 in the bottom of manhole cover 3, be provided with guide rail 2 below manhole cover 3, guide rail 8 is arranged in pressure container cylinder 1, and roller 8 can roll along guide rail 2.
The length of guide rail 2 should be no more than 2 times of location, bearing pin 9 place diameter of a circle, after falling and allly opening bolt soon, opened by manhole cover, can be pulled out by manhole cover easily.The length opening bolt 6 soon should be less than location, multiple bearing pin 9 place radius of a circle, to fall opening bolt soon after on manhole cover base plate, each bolt of opening soon can not be interfered mutually.
In addition, between the ring wall surface and shell ring 5 of manhole cover 3, seal arrangement 4 is also installed.Sealing device 4 can be O RunddichtringO, also can be metal loop seals.When adopting metal loop seals, seal groove should be set on the ring wall surface of manhole cover 2, metal loop seals is arranged in seal groove.
The using method of High Pressure Fast Open manhole device of the present utility model is as follows:
Manhole cover 3 is placed in pressurized container 1 inner, realizes the sealing with manhole 5 by seal arrangement 4.The pressurized gas of pressure container cylinder 1 inside act on manhole cover 3, play the effect compressing manhole cover 3, and then press seal part device 4, contribute to sealing.Now, seal load is only born by manhole cover 3, opens the weight of bolt 6 underwriter's port lids 3 soon, and provides seal preload, therefore can adopt small size bolt, convenient operation.
When needing to open manhole, all wing nuts 7 of outwarding winding, now, manhole cover 2 sinks along opening bolt 6 soon, until roller 9 contacts with guide rail 8.Then, rotate around bearing pin 9 and open bolt 6 soon, lain low in manhole cover 3, promote manhole cover 2 and slide along guide rail 8, open manhole, this operates single can completing.
When needing to close manhole, pull manhole cover 3, make it slide along guide rail 8.When manhole cover 3 and manhole 5 are coaxial, rotate and respectively open bolt 6 soon, be located in the mounting hole on manhole 5, screw wing nut 7 around bearing pin 9, make manhole cover 3 and manhole 5 be adjacent to and start compression seal device 4, this operation can singlely complete equally.
By using this High Pressure Fast Open manhole device, solve high pressure vessel manhole and open and close the problem wasted time and energy, achieve the fast opening and closing of high pressure vessel manhole, time and manpower is saved.
