Abstract
The invention relates to the technical field of railway transportation pressure containers, in particular to a tanker discharge valve opening/closing mechanism and a protection device. The tanker discharge valve opening/closing mechanism and the protection device are characterized in that a tank discharge valve protective cover and an opening/closing mechanism are provided; the opening/closing mechanism includes a lifting base and an opening/closing shaft; one end of the lifting base is fixed on the outer surface of a tank, and a through hole is formed in the other end of the lifting base; and an opening/closing shaft penetrates through the lifting base through hole and the protective cover, one end is connected with a discharge valve for opening or closing the discharge valve, and the other end is an operation end or is connected with an operation piece. The tanker discharge valve opening/closing mechanism and the protection device improve the tanker safety and reliability, and are convenient for operators to operate.
Description
Technical field
Railway transportation pressure vessel technology field of the present invention, is specifically related to a kind of tank car lower discharge valve opener and fender guard.
Background technology
In recent years, the event that transport and storage due to dangerous chemicals occur to leak occurs repeatedly, and causes high risks to the security of the lives and property of the people and ambient environment, and the whole society requires to improve constantly to harmful influence storing and transporting security.The medium of tank car shipment has the dangerous properties such as inflammable, explosive, burn into is poisonous mostly, once leakage initiation consequence is serious.China railways was through development in nearly ten years, and the safety of dangerous material tank car can meet the operating needs under nominal situation substantially.But compared with developed countries, tank car safety in the state of accident still has larger gap.The shortcoming of main existence is as follows:
For the tank car that unloads under adopting, when tank car derailing, topple time be easy to cause lower discharge valve to destroy or surprisingly open, cause 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 to lower discharge valve, reducing lower discharge valve and surprisingly opening risk and seem particularly important.
Technical scheme
For solving the problem in background technology, the present invention proposes that a kind of safety is high, reliability is high, and a kind of tank car lower discharge valve switching mechanism of convenient operation person operation and fender guard.
Concrete technical scheme of the present invention is:
The invention provides a kind of tank car lower discharge valve switching mechanism and fender guard, be provided with tank body letdown valve protective cover and switching mechanism; Described switching mechanism comprises flap seat, opening and closing shaft; Described flap seat one end is fixed on tank body outside face, 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, and for opening or closing lower discharge valve, the other end is operating side or is connected with operating parts.
Above-mentioned switching mechanism also comprises operating handle and operating handle safety jaw; Described opening and closing shaft is connected with lower discharge valve through through hole one end and is used for opening or closing lower discharge valve, and the other end is connected with operating handle; Described operating handle safety jaw comprises and is fixed on flap seat or right angle arm that the arm of tank base and arm are connected and the bearing pin that is inserted between arm and right angle arm; The overhanging portion of described operating handle is spacing by bearing pin.
Above-mentioned switching mechanism also comprises door lock, and described bearing pin offers aperture, and bearing pin pins through aperture by the lock ring of described door lock.
Aforesaid operations end is offered inner-hexagon spanner hole or is provided with outer hexagonal spanner and tightens spiral shell head.The invention has the advantages that:
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 operating handle and operating handle safety jaw, provides safety guard-safeguard, surprisingly can not open lower discharge valve under accident condition to operating handle.
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 invention.
Detailed description of the invention
In order to solve the unsafe problems that existing tank car lower discharge valve exists, the invention provides a kind of tank car lower discharge valve switching mechanism and fender guard.
As shown in Figure 1, the position of tank body 1 bottom installation letdown valve 2 is provided with protective cover 3 and switching mechanism 4;
Specifically, switching mechanism 4 comprises flap seat 5, opening and closing shaft 6; Flap seat 5 one end is fixed on tank body 1 outside face, and the other end is provided with through hole 7; Opening and closing shaft 6 is connected with lower discharge valve 2 through through hole 7 one end and is used for opening or closing lower discharge valve 2, 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 invention also comprises operating handle 8 and operating handle safety jaw 9; Opening and closing shaft 6 is connected with lower discharge valve 2 through through hole 7 one end and is used for opening or closing lower discharge valve, other end fitting operation handle 8; Operating handle safety jaw 9 comprises and is fixed on the right angle arm 11 that arm 10 on flap seat 5 or bottom tank body 1 and arm 10 are connected and the bearing pin 12 be inserted between arm 10 and right angle arm 11; The overhanging portion of operating 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 comprises door lock, and bearing pin 12 offers aperture, and bearing pin 12 pins through aperture by the lock ring of door lock.
In addition, the operating side that present invention also offers a kind of opening and closing shaft is inner-hexagon spanner hole or is provided with outer hexagonal spanner and tightens these two kinds of forms of spiral shell head.But also not exclusively only have this two kinds of forms, the operating side of opening and closing shaft is set to square or spline or other convenient operations shape.
