Description
Technical field
The utility model belongs to power plant's safety valve technical field, and in particular to a kind of power plant handle spring formula safety
Valve.
Background technology
Safety valve is opening and closing element lower in normally off by external force effect, when the pressure medium in equipment or pipeline rises superb
When crossing setting, the particular usage valve of specified value is exceeded by preventing pressure medium in pipeline or equipment to discharge medium outside system
Door.Safety valve belongs to automatic valve class, is mainly used on boiler, pressure vessels and pipes, and control pressure is no more than setting, to people
Body safety and equipment have run important protective effect.Note safety valve has to pass through pressure test could be used, and be needed in power plant
Using to power plant's handle spring formula safety valve.
Current power plant handle spring formula safety valve, operationally, trouble free service effect is poor.
Therefore, invent a kind of power plant and seem very necessary with handle spring formula safety valve.
Utility model content
The purpose of this utility model is to provide a kind of power plant's handle spring formula safety valve, to solve above-mentioned background technology
It is middle to propose current power plant's handle spring formula safety valve, operationally, the problem of trouble free service effect difference.
To achieve the above object, the utility model provides following technical scheme：A kind of power plant handle spring formula safety valve,
Including protective cover, adjusting screw rod, spring, bonnet, fairlead, flap, regulating valve, valve body, valve rod, Disc holder, media outlet, Jie
Matter import, valve seat and bolt hole, the upper end of the valve body are fixedly connected with the lower end of bonnet；The upper end protective cover of the bonnet
Lower end is fixedly connected；Adjusting screw rod is provided with the protective cover；Spring is provided with the bonnet；The upper end of the spring with
Adjusting screw rod is fixedly connected；Valve rod is provided with the spring；Fairlead is provided with the outside of the spring；Under the bonnet
End is fixedly connected with the upper end of valve body；Disc holder is provided with the valve body；The Disc holder is fixedly connected with the lower end of valve rod；
The lower end of the Disc holder is provided with flap；Regulating valve is provided with the valve body；The lower end of the valve body is fixed with valve seat and is connected
Connect.
Further, it is provided with bolt hole on the valve seat.
Further, the lower end of the valve body is provided with medium entrance.
Further, the side of the valve body is provided with media outlet.
Technique effect of the present utility model and advantage：Power plant handle spring formula safety valve, by by handle spring formula
Safety valve is arranged in the conveyance conduit in power plant, using the pressure itself and the telescopic action of spring of the medium in system pipeline
Power realizes the separation of flap and valve seat and closure, so as to be automatically obtained the closure or openness of valve, when the pressure of medium in system
When power increases to over the permissible value of regulation, the upward thrust of medium is acting downwardly on the stretch on flap more than spring, is at this moment situated between
Matter thrust top valve opening valve, spring contraction, valve is automatically turned on, then full dose discharge, and the pressure of medium continues to rise in anti-locking system
Height, when pressure is released when being reduced to regulation, the downward stretch on flap of spring effect has been more than the upward thrust of medium,
Spring elongation resets, and flap returns seat, and valve is closed in time immediately, so as to ensure the safe operation of equipment so that power plant's handle
Spring loaded safety valve, operationally, trouble free service effect is good.
