Description
Technical field
The present invention relates to valve, specifically biologic medical machinery clean system safety valve.
Background technique
The safety valve application of currently available technology is on the pipeline or pressurized container of protected system, to guarantee the Security of pipeline or pressurized container, but for biologic medical machinery clean system, all there is certain defect in current safety valve, action is smooth not when opening or closing, and affects using effect; The easy Set pressure that affects equipment during earthquake back pressure pressure, and Component are very easily subject to the corrosion of medium in use, have slowed down working life, power consumption increases, and valve rod can be subject to the deflection influence automatic centering of spring, and sensitivity reduces; Without overpressure protector etc.So to health and the high place of cleanliness standard-required, the safety valve using must completely newly be developed for medical apparatus and wine brewing, beverage industry.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the biologic medical machinery clean system safety valve of above-mentioned disappearance.
Summary of the invention
The object of the present invention is to provide biologic medical machinery clean system safety valve, this product specification is rigorous, and hygienic requirements condition is high, good seal performance, and cracking pressure is accurate, has filled up the blank of domestic such health valve.
In order to reach above-mentioned purpose, the present invention has adopted following technological scheme, and biologic medical machinery clean system safety valve, comprises valve body, valve gap, valve rod, and described valve rod is arranged on by valve body and valve gap and fastens the valve pocket inside forming; Described valve rod lower end is connected on flap by guide pin bushing, and described flap bottom is connected to the top of the valve seat being connected with valve body simultaneously; Described valve rod periphery cover has spring, and this spring upper end is connected to the Adjusting bolt Adjusting screw bottom being enclosed within equally on valve rod by upper spring seat, and this spring lower end is connected to the guide pin bushing top being enclosed within equally on valve rod by lower spring cup; Described guide pin bushing runs through the guide sleeve center that is fixed on, and guiding casing pressure is stuck in valve body and the valve gap place that connects.
Described valve rod is threaded with guide pin bushing, and guide pin bushing is connected on flap by flap nut again, and inverted cone groove is offered at flap top, is provided with steel ball in groove, and described guide pin bushing bottom is connected on the steel ball in groove.
Between described guide sleeve and flap, be provided with bellows, this bellows upper end is pressed and is stuck in valve body and the valve gap place that connects together with guide sleeve, and lower end is fixed on flap by bellows nut and has covered the top of targeting part and the flap of flap.
Described valve seat epimere outside cover has lower Adjusting ring, and described flap outside cover has rise pitch circle.
Described valve rod upper end Adjusting bolt Adjusting screw outside screw be placed in valve gap top and cap, described valve stem tip is provided with hoisting nut, in valve gap upper end, safety cover is set, and cap, hoisting nut all protect within it, the spanner of this hoisting nut connection safety cover outside.
Described valve body docks fixing with valve gap by clip.
Compared to prior art, the present invention has following beneficial effect:
This valve is mounted on the pipeline or pressurized container of protected system, when pressure raises in protected system, produces an additional force acting on primary element, this element is moved and in this valve passage opening clearance, namely valve is opened automatically.Medium is discharged by gap, causes the pressure medium of pressurized container to return to below working pressure, the sealing state of rest of valve in closing now, thus reached protection equipment by the effect of superpressure.That is: when the pressure medium of valve body and valve seat flap inner chamber is elevated to certain value, flap is stressed after impact, promotes valve rod and lower spring cup and forces spring to do compression movement, and flap departs from valve seat and upwards rise, quick drain then, and now valve is opened automatically.When pressure medium is during in normal operating pressure, this valve, under the effect of spring force, cuts out again.
Design adopts bellows component balance type structure, is that a bellows is set on flap, and the upper end of bellows links together by clip guide pin bushing and guide sleeve, and lower end is connected with flap and has covered targeting part and the flap top of flap.There are like this two effects.The first effect is that the back pressure area that is subject to that guarantees flap above and below equates; the useful area that is bellows equates with the area of flap sealing surface of seat; while guaranteeing earthquake back pressure pressure, do not affect the Set pressure of this equipment; another one effect is that medium and valve gap are isolated; protection Component can not be subject to the erosion of medium; thereby guaranteed the stability of equipment and increased the service life, energy-saving and cost-reducing.Between design valve rod and flap, by quenching steel ball, connect, can guarantee that valve rod is not subject to the impact of spring deflection and automatic centering, has guaranteed the sensitivity of flap action.
Safety cover hoisting nut and spanner support the use, and effect is when steam or pressure medium reach 75 ﹪ cracking pressure, can pull spanner to check its flexibility, to meet the requirement of boiler attendance rules.Lower spring cup, upper spring seat and Adjusting bolt Adjusting screw cap coordinate, and are used for adjusting the power of spring, realize the discharge pressure of this valve and Reseating pressure of a safety valve, thereby determine its performance in conjunction with the span of adjusting rise pitch circle and lower Adjusting ring.
This valve is applicable to the overpressure protection of low pressure steam, gas or liquid plant, pipeline, pressurized container; be particularly useful for medical apparatus and wine brewing, beverage industry to health and the high place of cleanliness standard-required, to keep high-quality product and the pollution of operation medium to be down to minimum.This product specification is rigorous and novel, and hygienic requirements condition is high, good seal performance, and cracking pressure is accurate, the external imported product of alternative similar A28 type.Filled up the blank of domestic such health valve.
