The utility model discloses an improvement part be: it lets out valve protection casing and closing mechanism to be equipped with under jar body, closing mechanism includes flap seat, switching axle, flap seat one end is fixed on the external surface of jar, and the other end is provided with the through -hole, the switching axle passes flap seat through -hole and protection casing, and one end is unloaded the valve under with and is connected for opening or closing down and unload the valve, the other end is connected for operation end inclusive AND operating parts. Through using the utility model provides the high security and the reliability of tank car to be convenient for operator operation.
Description
Technical field
This utility model railway transportation pressure vessel technology field, is specifically related to a kind of tank car lower discharge valve opener and protection device.
Background technology
In recent years, owing to transport and the storage of dangerous chemicals occur the event of leakage to occur repeatedly, causing high risks to the security of the lives and property of the people and surrounding enviroment, harmful influence storing and transporting security is required to improve constantly by the whole society.The medium of tank car shipment has the hazard properties such as inflammable, explosive, burn into is poisonous mostly, once leakage causes consequence serious.China railways develops through last decade, and dangerous materials tank car safety disclosure satisfy that the instructions for use under nominal situation substantially.But, compared with developed countries, tank car safety in the state of accident still has bigger gap.The shortcoming being primarily present is as follows:
For the tank car unloaded under adopting, it is easy to when tank car derails, topples cause lower discharge valve to destroy or unexpected unlatching, causes the leakage of medium in tank, cause serious consequence.In order to improve leakage prevention capability under tank car accident condition, taking effective and safe to protect lower discharge valve, reduction lower discharge valve is surprisingly opened risk and is particularly important.
Utility model content
For solving the problem in background technology, the utility model proposes a kind of safety height, reliability height, and be easy to a kind of tank car lower discharge valve switching mechanism and the protection device of operator's operation.
Concrete technical scheme of the present utility model is:
This utility model provides a kind of tank car lower discharge valve switching mechanism and protection device, is provided with tank body letdown valve protective cover and switching mechanism；Described switching mechanism includes flap seat, opening and closing shaft；Described flap seat one end is fixed on tank body outer surface, and the other end is provided with through hole；Described opening and closing shaft is through flap seat through hole and protective cover, and one end is connected with lower discharge valve, is used for being turned on and off lower discharge valve, and the other end is operating side or is connected with operating parts.
Above-mentioned switching mechanism also includes operation handle and operation handle safety jaw；Described opening and closing shaft is connected with lower discharge valve is used for being turned on and off lower discharge valve through through hole one end, and the other end is connected with operating handle；Described operation handle safety jaw includes being fixed on flap seat or the arm of tank base and arm are connected right angle arm and the bearing pin being inserted between arm and right angle arm；The overhanging portion of described operation handle is spacing by bearing pin.
Above-mentioned switching mechanism also includes door lock, and described bearing pin offers aperture, and bearing pin is pinned by the lock ring of described door lock through aperture.
Aforesaid operations end is offered inner hexagon spanner hole or is provided with outer hexagonal spanner and tightens screw head.The utility model has the advantage of:
1. tank base lower discharge valve arranges safety device and switching mechanism, and when can avoid accident, lower discharge valve is cut off.
2, switching mechanism adopts operation handle and operation handle safety jaw, provides safeguard protection to operation handle, will not surprisingly open lower discharge valve under accident condition.
3, switching mechanism installs door lock, can prevent the accident of stealing crude oil from occurring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to solve the unsafe problems that existing tank car lower discharge valve exists, this utility model provides a kind of tank car lower discharge valve switching mechanism and protection device.
As it is shown in figure 1, the position that letdown valve 2 is installed in tank body 1 bottom is provided with protective cover 3 and switching mechanism 4；
Specifically, switching mechanism 4 includes flap seat 5, opening and closing shaft 6；Flap seat 5 one end is fixed on tank body 1 outer surface, and the other end is provided with through hole 7；Opening and closing shaft 6 is connected with lower discharge valve 2 is used for being turned on and off lower discharge valve 2 through through hole 7 one end, and the other end is provided with inner hexagonal hole or outer-hexagonal spindle nose.
For the ease of operator's opening and closing lower discharge valve, switching mechanism 4 of the present utility model also includes operation handle 8 and operation handle safety jaw 9；Opening and closing shaft 6 is connected with lower discharge valve 2 is used for being turned on and off lower discharge valve through through hole 7 one end, and other end installation operates handle 8；Operation handle safety jaw 9 includes being fixed on the arm 10 on flap seat 5 or bottom tank body 1 and arm 10 is connected right angle arm 11 and the bearing pin 12 being inserted between arm 10 and right angle arm 11；The overhanging portion of operation handle 8 is spacing by bearing pin 12.
In order to prevent the thing of stealing crude oil from occurring, this switching mechanism 4 also includes door lock, and bearing pin 12 offers aperture, and bearing pin 12 is pinned by the lock ring of door lock through aperture.
It is inner hexagon spanner hole it addition, this utility model additionally provides the operating side of a kind of opening and closing shaft or is provided with outer hexagonal spanner and tightens screw head both forms.But and not exclusively only have both forms, the operating side of opening and closing shaft be set to square or spline or other be easy to operation shape.
