Description
Technical field
Field of chemical equipment is the utility model is related to, is specially a kind of atmospheric pressure device Novel quick-opening formula manhole.
Background technology
In existing atmospheric pressure device manufacturing process, bought according to national chemical industry mark for equipment manhole
The type of manhole that standard makes, for the atmospheric pressure device of part chemical industry, manhole also requires tool sometimes in process of production
The function of standby peep hole, thief hole and charging aperture.Therefore the quick opening manhole made according to existing codes and standards, opened frequently
Just seem in journey extremely inconvenient.
At present quick opening manhole there are the problem of be：Quick opening manhole on chemical industry equipment is substantially according to HG/T21525-
2014 normal pressure swing handle quick-opening manholes carry out making production, and manhole component makes trouble.For some interior anti-corrosions of petrochemical industry
It has been completed that, the equipment for the welding that do not allow to get angry adds multipurpose manhole, commercially buys finished product manhole or according to industry standard
Making can all produce larger problem.
The manhole cap assemblies of the Novel quick-opening manhole can be welded and fixed with apparatus body, and can use spiral shell with apparatus body
Bolt fastens, and avoids external condition from not allowing the factor of welding to lead to not add quick opening manhole.
Utility model content
A kind of the shortcomings that trouble being made the purpose of the utility model is to overcome existing quick opening manhole's component, there is provided structure letter
It is single, safeguard and operating cost is cheap, while manufacture requires relatively low Novel quick-opening manhole.
Technical solution is used by the utility model solves above-mentioned technical problem：
A kind of normal-pressure chemical equipment Novel quick-opening formula manhole, including manhole flange lid and handwheel, the manhole flange lid with
Manhole flange and manhole shell section linking, the manhole flange side of covering are equipped with stiffener plate, the utilization of manhole flange lid support cylinder with
Clamping screw is fixed together, and is fixed handwheel above the clamping screw；
A support arm is connected in side using fixing nut on clamping screw below the handwheel, the support arm is another
One end passes through spiral shell by bearing housing and a rotation axis connection, the rotation axis lower section using one piece of bearing plate and equipment shaped steel
Bolt is fixed.
The form of the support arm is the group welding piece of triangle, and top is level board, and lower section is the plate of 15 ° of inclination, both
Between be connected with set square.
The beneficial effects of the utility model：1st, compact-sized and simple, opening and closing is flexible；2nd, safeguard and operating cost is cheap；
3rd, make easy to some chemical industry equipments or should not add quick opening manhole under welding condition using the later stage.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model device.
In figure：1- manhole shell sections, 2- clamping screws, 3- manhole flange lids, 4- handwheels, 5- support arms, 6- rotation axis, 7- branch
Support bottom plate, 8- connection shaped steel, 9- bearing housings, 10- manhole flanges, 11- supporting cylinders, 12- stiffener plates.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of normal-pressure chemical equipment Novel quick-opening formula manhole, including manhole flange lid 3 and handwheel 4, it is described
Manhole flange lid 3 is connected with manhole flange 10 and manhole shell section 1, and the top of manhole flange lid 3 is equipped with stiffener plate 12, manhole
For blind flange 3 using cylinder 11 is supported and clamping screw 2 is fixed together, the top of clamping screw 2 is fixed handwheel 4；
On the clamping screw 2 of the lower section of handwheel 4 support arm 5, the support are connected in side using fixing nut
5 other end of arm is connected by bearing housing 9 and a rotation axis 6, and the lower section of rotation axis 6 utilizes one piece of bearing plate 7 and connection
Shaped steel 8 is fixed.
The form of the support arm is the group welding piece of triangle, and top is level board, and lower section is the plate of 15 ° or so of inclination,
It is connected between the two with set square.
Operating process：When needing to close manhole, rotate handwheel 4 and drive clamping screw 2, supporting 11 He of cylinder is given by power transmission
Stiffener plate 12 is to the pressure rapid sealing manhole of manhole flange lid 3.When needing quick opening manhole, handwheel 4 is rotated with dynamic pressure
Tight screw rod 2, by supporting cylinder 11 and stiffener plate 12 to 3 unloading pressure of manhole blind flange, and manhole flange lid 3 is lifted to one
Fixed height, is at this moment sent to bearing housing 9, rotation axis 6 is driven and carried by bearing housing 9 and support arm 5 by support arm 5 by power
The manhole cover rotation risen is quickly removed, and work is started in completion soon, facilitates operating personnel to enter.The lower section of rotation axis 6 utilizes a piece of support
Bottom plate 7 and connection shaped steel 8 are fixed.
Above content is only to the utility model example and explanation, affiliated those skilled in the art couple
Described specific embodiment does various modifications or additions or substitutes in a similar way, without departing from practical new
The design of type surmounts scope defined in the claims, all should belong to the protection range of the utility model.
