Background technique
The bellows safety valve is balanced safety valve again.Be a kind of releasing pressure automatically protective equipment of being opened by the import static pressure, mobile equilibrium outlet back-pressure surges or isolation aggressive medium are to the corrosion of spring.It is one of of paramount importance safety attachment of pressurized container, and 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 is applicable to that mainly outlet exists fluctuation back pressure, Korrosionsmedium, on the equipment and pipeline of media such as the air of operating temperature≤300 ℃, steam, petroleum gas, 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.In order to guarantee the seal of safety valve; Therefore bellows and the valve rod of existing bellows type safety valve all weld together, but safety valve when reality is used, need regularly study, when finding bellows appearance damage; Then need need whole replacement, so cost of production is very high.
The model utility content
The purpose of the utility model is to have the deficiency that maintenance is inconvenient, maintenance cost is high in order to overcome when above-mentioned bellows and valve rod weld, and a kind of Bellows seal balance safety valve is provided.
The utility model says that to achieve these goals the technological scheme of employing is following: a kind of Bellows seal balance safety valve; It comprises valve body, valve seat, flap, Disc holder, bellows, valve rod, spring, spring spool and bonnet; Wherein bonnet is installed in the spring spool top; The spring spool bottom connects the top of valve body, and valve seat is installed in the valve body bottom; Said valve rod runs through spring spool, and the top is positioned at bonnet, and the bottom is positioned at bellows; Said spring housing is contained on the valve rod and is positioned at spring spool; The bottom that it is characterized in that said bellows is threaded with Disc holder; The upper end cooperates with the valve body inner stopper, and the Disc holder upper end is set with the valve rod end portion, and the part of this Disc holder suit valve rod is sleeved in the bellows; The Disc holder lower end covers flap and is movably connected with flap, and flap and valve seat are through grinding-in; Also be provided with guide sleeve between said Disc holder and the bellows.
The technological scheme that is more preferably in the utility model is: establish the self-alignment cushion block in the Disc holder, this cushion block is connected with the contact of valve rod bottom.
The said valve rod that is positioned at spring spool is provided with valve rod cushion block, lower spring cup and upper spring seat, and lower spring cup is positioned on the valve rod cushion block, and the valve rod of upper spring seat top is provided with adjusting screw rod, and adjusting screw rod is fixed on the spring spool top through locking nut.The spring upper end is connected on the upper spring seat, and the lower end is connected on the lower spring cup.
Said bonnet top is provided with plug.
The utility model is through setting up screw thread in the bellows bottom, thereby makes and be threaded between bellows and the Disc holder, therefore convenient maintenance, and tightness also is guaranteed.
