Safety valve is a kind of safety protection valve; its open-shut device is in normally off by under External Force Acting; when the pressure medium in equipment or pipeline raises, automatically open when exceeding specified value, exceed specified value by preventing pressure medium in pipeline or equipment to discharge medium outside system.
The rated pressure of the safety valve used on some equipment in prior art can only be fixing, directly limit the usability of equipment, need then can not reach usage requirement in the use field of ultrahigh pressure at some, if wish that the rated pressure on equipment improves the safety valve just needing more to renew.
Safety valve after a long time use in addition, spring loaded is easy to occur that modification is aging, and safety valve performance is declined along with use, has shortened the working life of safety valve, make safety valve need often to change, cause much unnecessary trouble to the maintenance in later stage and improve maintenance cost.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of spring loaded elastic force adjustable and spring loaded changes easy safety valve after damaging.
For achieving the above object, the utility model provides following technological scheme: a kind of one-way relief valves, comprise valve body and be arranged on the groove in valve body, in described groove, spring loaded is installed, adjustable lever is provided with in described groove, described adjustable lever is provided with regulator plate, described regulator plate is positioned at spring loaded one end near the opening of groove, described regulator plate slippage can be used for compression or tension load spring on adjustable lever, the sidewall of described groove is provided with the chute for regulator plate locating slip, the opening of described groove is detachably provided with end cap, described adjustable lever is installed on end cap.
By adopting technique scheme, pass through rotation adjusting lever, contrary between adjustable lever with regulator plate rotation can be made, regulator plate can be moved up and down on adjustable lever, and regulator plate can be conflicted spring loaded, spring loaded is made to compress in groove or extend, make it possible to by regulating regulator plate and the elastic force of regulating load spring, safety valve can be made to be applicable to multiple occasion, and when spring loaded elastic force weakens, regulate regulator plate that spring loaded compress, can the elastic force of proof load spring, make the service time of prolongation safety valve.
The utility model is set to further: described adjustable lever is connected by screw-thread fit with between regulator plate.
By adopting technique scheme, rotary regulating lever can make regulator plate move up and down on adjustable lever, can easy operating process by screw-thread fit.
The utility model is set to further: the contacting point of described end cap and adjustable lever is provided with circular track, and described adjustable lever is provided with the slide block be placed in circular track.
By adopting technique scheme, adjustable lever can be made to rotate on end cap and to avoid adjustable lever to come off from end cap, using effect and the structure stability of safety valve can be improved.
The utility model is set to further: described adjustable lever is provided with baffle plate away from one end of end cap.
By adopting technique scheme, situation about coming off from adjustable lever when regulator plate can be avoided to move on adjustable lever, improves using effect and the structure stability of safety valve.
The utility model is set to further: the sidewall that described end cap contacts with groove is provided with draw-in groove, slide in described draw-in groove and have fixture block, be provided with the elastic component ejected for fixture block in described draw-in groove, the sidewall of described groove corresponds to the fast place of card and is provided with the through hole worn for fixture block.
By adopting technique scheme, making removably connects between end cap and valve body facilitates the dismounting of end cap and safeguards safety valve and can avoid safety valve operationally end cap situation about coming off from valve body, ensure that the using effect of safety valve.
The utility model has following advantage: arrange the telescopic resilience power that adjustable lever and regulator plate make adjustable spring loaded, safety is cut down can adapt to multiple use occasion and long-time working load spring still can the elastic force of proof load spring.
