Description
Technical field
The utility model relates to a kind of valve, particularly a kind of valve that shows.
Background technology
Pressure cooker is in use inner can produce very high pressure, under high pressure conditions, open pressure cooker extremely dangerous, in use in order to point out the pressure condition in user's pressure cooker pressure cooker, on pressure cooker, be provided with demonstration valve, user shows that by observation valve can judge whether pressure cooker can be opened.
Current demonstration valve is mainly indicated by the color on valve, the disclosed safety valve of pressure cooker of for example Chinese patent literature [CN2548513Y], comprise that loading pressure cooker covers the valve seat with through hole, be applied in the stopping valve bar that on through hole, also can slide up and down, on stopping valve bar with the bubble head that can stretch out handle, stopping valve bar middle part and lower end are embedded with respectively sealing ring and the sealing gasket of energy seal valve seat through hole, and bubble head is provided with color.It is shaft-like that bubble head is, and therefore color is up and down and distributes at bubble head, can be stained with some dirts color is covered, or after long-time use, color desalination causes indistinguishable when reality is used on bubble head.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of demonstration valve, and the technical problem that the utility model solves is more easily to differentiate the indication showing on valve.
The purpose of this utility model can realize by following technical proposal: a kind of valve that shows, comprise valve seat and valve rod, it is characterized in that, on described valve seat, there is groove, in described groove, be provided with at least two indicator collets that connect successively, described valve rod upper end and one of them indicator collet are fixed, and described indicator collet is step-like distribution when valve rod rises, and are provided with the elastic component that makes its hold reset trend when valve rod rises between described valve rod and valve seat.
The lower end of valve rod is fixed with valve head, and the pressure in pressure cooker is passed to valve rod by valve head; When the pressure in pressure cooker increases, can promote valve rod and rise, valve rod is by the indicator collet jack-up fixing with it, and elastic component is for the pressure of balanced action on valve rod, and along with the increase of pressure, the height that valve rod rises is higher, and other indicator collet also can be successively by jack-up; Owing to being step-like distribution by the indicator collet of jack-up, be three-dimensional and distribute, pressure is larger, more by the indicator collet of jack-up, and pressure indication is more directly perceived, and user more easily differentiates.
In above-mentioned demonstration valve, described indicator collet comprise passive indicator collet and with the fixing active indicator collet of valve rod, described active indicator collet is cylindrical, the cross section of described passive indicator collet is annular, described active indicator collet is positioned at the center of groove, and described passive indicator collet is enclosed within on active indicator collet and is arranged in order.While increasing in pressure cooker, passive indicator collet and initiatively indicator collet are step-like distribution, and initiatively indicator collet is positioned at highest point, and passive indicator collet is step-like decline successively, and third dimension is strong, and pressure indication is directly perceived.
As another kind of situation, in above-mentioned demonstration valve, described indicator collet comprise passive indicator collet and with the fixing active indicator collet of valve rod, described active indicator collet and passive indicator collet are all the square bodily form, described passive indicator collet is evenly distributed successively in active indicator collet both sides.While increasing in pressure cooker, passive indicator collet and initiatively indicator collet are step-like distribution, and initiatively indicator collet is positioned at highest point, and passive indicator collet is step-like decline successively, and third dimension is strong, and pressure indication is directly perceived.
In above-mentioned demonstration valve, the color of described passive indicator collet and initiatively indicator collet is all not identical.Color makes the difference between indicator collet more obvious, and the safe coefficient of reaction pressure that can be clearer and more definite by color, the contrast by color and have more relief demonstration and make pressure indication more directly perceived.
In above-mentioned demonstration valve, described passive indicator collet all has recessed shoulder on the side near active indicator collet, described recessed shoulder is towards groove floor, and described active indicator collet has initiatively baffle plate, and described active baffle plate is positioned at the recessed shoulder of the passive indicator collet adjacent with active indicator collet; In adjacent two described passive indicator collets, near the passive indicator collet of active indicator collet, have passive baffle plate, described passive baffle plate is positioned at the recessed shoulder of the passive indicator collet adjacent with the passive indicator collet in passive baffle plate place.When initiatively indicator collet rises, by active baffle plate, drive adjacent passive indicator collet to rise, passive indicator collet drives adjacent passive indicator collet to rise by passive baffle plate successively.
In above-mentioned demonstration valve, described active baffle plate is identical with the distance of passive baffle plate and recessed shoulder upper side with the distance of recessed shoulder upper side.Guarantee that the drop height between indicator collet initiatively and adjacent passive indicator collet and adjacent passive indicator collet is identical, initiatively more attractive in appearance when indicator collet and the rise of passive indicator collet.
In above-mentioned demonstration valve, the end of described active baffle plate and passive baffle plate all has limited impression, and described recessed shoulder side has projection, described projection can with the cell wall of limited impression against.When pressure reduces, elastic component makes active indicator collet to decline, initiatively baffle plate and passive baffle plate and projection are against driving adjacent passive indicator collet to move to groove, active indicator collet and passive indicator collet are all fallen back in groove, projection can prevent that passive indicator collet from coming off, and plays the effect of location simultaneously.
In above-mentioned demonstration valve, described valve rod middle part has annular convex shoulder, and described active indicator collet comprises the connecting portion through valve seat, and described connecting portion axially offers connecting hole along it, described valve rod upper end through connecting hole and with connecting portion axial restraint, described connecting portion end and annular convex shoulder against.Between valve rod and connecting portion, be tight fit, annular convex shoulder is for determine that valve rod stretches into the length of connecting hole when assembling, convenient for assembly.
In above-mentioned demonstration valve, described elastic component is volute spring, and described volute spring is enclosed within on connecting portion, one end that described volute spring diameter is larger and valve seat against, one end that described volute spring diameter is less and annular convex shoulder against.The pressure history of volute spring when compressed more approaches the change curve of pressure cooker internal pressure, makes the situation of the easier reaction pressure pot inner pressure of the indicated pressure of indicator collet.
As another kind of situation, in above-mentioned demonstration valve, described elastic component is cylindrical spring, and described cylindrical spring is enclosed within on connecting portion, one end of described cylindrical spring and valve seat against, the other end of described cylindrical spring and annular convex shoulder against.
Compared with prior art, it is more directly perceived that this demonstration valve has pressure indication, the advantage that user more easily differentiates.
