Description
Technical field
The utility model is related to a kind of explosion prevention manhole covers of petrochemical industry.
Background technology
In petrochemical industry, some is sewage disposal facility to underground pipe network, and the mixed of various water is contaminated in these pipelines
Close object, such as greasy dirt, rainwater, fuel gas ingredient.Scene needs draining, there are the wells that many and ground communicates for the needs of dredging
Mouthful.Due to more complex for sewage disposal facility interior media ingredient, do not pay attention to that slightly fire or explosion will be caused, directly threaten production
Safety.Existing most of petrochemical industries use common ductile cast iron manhole cover, well lid top to spread sand in well head, are come with this
The nuisance that the open fire on ground does not enter in well and in well is allowed to be not leak into the method on ground to handle.There are more for this method
Drawback is secondly really to want explosion on fire, existing well lid meeting caused by the not necessarily external open fire on fire of combustible in well first
It is blown up by air blast, open fire spreads out at once, threatens Field Force and equipment.Technologies in Petrochemical Industry is multiple due to this problem
Appearance accident causes chain explosion on fire.
Utility model content
For the deficiency of original inspection well cover, explosion prevention manhole cover can solve the above-mentioned problem, such inspection well cover according to
Explosive-proof sealed requirement is designed, and completely isolated inspection shaft interior media and external access, inspection shaft are stamped closedown structure, convenient
The installation and maintenance at scene.
The technical solution of the utility model is specially：
A kind of explosive-proof sealed well lid includes well seat, well lid and locking device, and well seat 1 fixes on the ground, and well lid covers kill-job
On seat and part well lid extends to inside well seat, and the interconnecting piece of the two is equipped with multiple locking devices, locking device include movable block,
Baffle；
The upper surface of the side wall of well seat is equipped with the locked groove of installation locking device, and locked groove includes circular trough and arc groove, circle
The width of slot is d1；A baffle is all fixed on the cell wall on the both sides of arc groove, there is distance D, two baffles between two baffles
It is the T shapes stood upside down to make the section of arc groove, and the width of arc groove slot bottom is d2；The top of movable block is fixed on the following table of well lid
The width in face, the middle part of movable block is d3, and the width of the lower part of movable block is d4；4 ＞ D ＞ d3, d1 ＞ d4, d2 ＞ d4.
The fixation of baffle and well seat is fixed by screw.
Well lid is equipped with annular groove on the top for the cylindrical face that well seated connection touches, and O-ring seals are equipped in annular groove.
The upper surface of well seat is equipped with annular projection on the contact surface with well lid, and dovetail is equipped between annular projection and well lid
Sealing ring.
Compared with the existing technology, the technique effect of the utility model is that the utility model will be equipped between well seat and well lid
Locking device completes the locked of both, and is equipped with sealing ring, has completely cut off inspection shaft completely and has been contacted with extraneous, has been pacified very much
Entirely.

Specific implementation mode
Such as Fig. 1-5, a kind of explosive-proof sealed well lid includes well seat 1, well lid 2 and locking device 3, and well seat 1 fixes on the ground,
On 2 sets of kill-job seats 1 of well lid and part well lid 2 extends to inside well seat 1, and the interconnecting piece of the two is equipped with multiple locking devices 3, locking
Device 3 includes movable block 5, baffle 6.
The upper surface of the side wall of well seat 1 is equipped with the locked groove 9 of installation locking device 3, and locked groove 9 includes circular trough 91 and arc groove
92, the width of circular trough 91 is d1.
A baffle 6 is all fixed on the cell wall on the both sides of arc groove 92, has distance D, two baffles to make between two baffles 6
The section of arc groove 92 is the T shapes stood upside down, and the width of 91 slot bottom of arc groove is d2.
The top 51 of movable block 5 is fixed on the lower surface of well lid 2, and the width at the middle part 53 of movable block 5 is d3, movable block 5
Lower part 52 width be d4.
D4 ＞ D ＞ d3, d1 ＞ d4, d2 ＞ d4.
Baffle 6 and the fixation of well seat 1 are fixed by screw.
In order to facilitate sealing, well lid 2 is equipped with annular groove on the top for the cylindrical face that well seat 1 contacts, and O shapes are equipped in annular groove
Sealing ring 7.
In order to facilitate sealing, the upper surface of well seat 1 with annular projection 15, annular projection are equipped on the contact surface of well lid 2
Dovetail sealing ring 9 is equipped between 15 and well lid 2.
Its working principle is that：
When installation, so that movable block 5 is directed at circular trough 91, well lid is pressed on well seat, at this point, movable block 5 is whole to enter circle
In shape slot 91.
Well lid is rotated counterclockwise with unlock spanner 4（Such as from position c movement positions d）, movable block 5 is also with rotation（From
Position a movement positions b）, at this point, movable block 5 moves at arc groove 91, because of d4 ＞ D ＞ d3, the middle part 53 of movable block 5 is blocked
