Description
Technical field
The utility model relates to safety valve, particularly a kind of convenient maintenance, the safety valve that maintenance cost is low.
Background technique
Safety valve is a kind of releasing pressure automatically protective equipment of being opened by the import static pressure; It is one of of paramount importance safety attachment of pressurized container; Its function is: when container inner pressure surpasses certain certain value, rely on the automatic Open valve of pressure of medium self, discharge the medium of some rapidly.When the pressure in the container dropped to permitted value, valve cut out again automatically, made container inner pressure be lower than the upper limit of authorized pressure all the time, prevented the accident that possibly occur because of superpressure, the final protective gear of pressurized container so the bellows safety valve is otherwise known as automatically.The bellows safety valve mainly is applicable on the equipment and pipeline of media such as the air, steam, petroleum gas of operating temperature≤600 ℃, as overpressure protector.When equipment and pipeline inner pressure surpassed permitted value, valve was opened automatically, full dose discharging then; When pressure was reduced to specified value, valve was closed automatically, guaranteed equipment safety operation.Be widely used at present in the industry such as electric power, metallurgy, oil, chemical industry.Existing safety valve is for its seal, mainly is to adopt jump ring to be connected or the mode that is threaded between Disc holder and the flap wherein, and the problem that adopts the two mode mainly to exist is in use jump ring, screw thread corrosion.Full valve all need regularly overhaul; Maintenance in general 1 year one; Therefore in reaching year safety valve can jump ring or its screw thread rust wearing and tearing anyway can appear, thereby cause the joint stuck, make that flap is difficult for taking out; Therefore can only be with flap and the whole replacement of Disc holder, maintenance cost improves greatly.
The model utility content
The purpose of the utility model is to exist Disc holder and the easy stuck scene of flap to cause the high deficiency of maintenance cost in order to overcome above-mentioned safety valve, and a kind of simple in structure, easy to operate safety valve is provided.
The technological scheme that the utility model is adopted to achieve these goals is following:
A kind of safety valve of easy access comprises valve seat, is installed in valve body, flap, Disc holder, guide sleeve, valve rod, spring, spring spool and bonnet on the valve seat, and its medi-spring is positioned at spring spool; Said bonnet bottom connects the spring spool top; The spring spool bottom is installed in the valve body top, and said flap is installed in the Disc holder, and valve rod runs through spring spool; Valve stem tip is positioned at bonnet; The bottom is positioned at Disc holder, wherein is positioned at the valve rod cushion block that is with spring, lower spring cup, upper spring seat on the part of spring spool and is used to support lower spring cup, and valve stem tip is provided with adjusting screw rod; It is characterized in that said flap and Disc holder are provided with screw, Disc holder flexibly connects through screw and flap.
The technological scheme that is more preferably in the utility model is to be provided with plug on the bonnet top; Adjusting screw rod is provided with locking nut, and adjusting screw rod is stuck in the spring spool top through this locking nut; Said spring spool is installed in the valve body top through bolt; Also be provided with on the said valve body be installed in valve seat on the combination jackscrew that is connected of Adjusting ring contact; Said valve rod and Disc holder contacting point also are provided with cushion block; Said guide sleeve is sleeved on the Disc holder and with valve body and is connected with the spring spool Spielpassung.
The utility model is through being connected making screw between Disc holder and the flap, when maintenance, only needs screw with both sides to take out and get final product, even also stuck phenomenon can not occur because screw gets rusty, the while has also guaranteed the sealing of safety valve.So the utlity model has advantages such as simple in structure, easy to operate, that maintenance cost is low, be fit to promote the use of widely.
