Referring to Fig. 1, one uses safety valve 10 of the present invention, typical, of the prior art to comprise valve body 11, and it has flanged (FLGD) inlet union 12 and outlet connection 13.One uncovered york piece 14 is installed on the valve body, is supporting valve rod 15, but is installed on the interior valve rod of york piece by the helical spring 21 of lifting component 20 manual manipulation valve rods 15, one precise windings, and is compressed between spring block 22 and 23.Lower spring block 23 can cooperate with the outside conical process seat 24 on valve rod.Valve disc 25 is installed in the lower end of valve rod, and the lower end of valve rod is positioned at mounting guide sleeve or the valve disc retaining member of being fixed by valve disc nut 31 30.Valve disc 25 has a downward and intilted annular lip structure 32, and it limits one 45 ° seat, and this can cooperate with 45 ° of valve seats 33 on cover for seat 34, and that cover for seat 34 is installed in inlet union 12 is interior and form a circulation road that leads to safety valve.

During work, safety valve 10 of the prior art is installed in (not shown) on the pressurized container, so that be used for discharging the excessive hydrodynamic pressure that may form in pressurized container.Hydrodynamic pressure in container is communicated with safety valve by the circulation road 35 34 li of the cover for seat of valve.Safety valve keeps cutting out by the pressure spring 21 that pushing valve disc 25 and the valve seat 33 on cover for seat 34 are sealed and matched.When the pressure in the pressurized container was increased to the setting pressure of safety valve, pressure at first reached level under setting pressure, that make valve begin to leak, so that prepare for opening fully when setting pressure.The stress level that makes valve begin to leak is called " seat leak tightness ", and it is with to open pressure relevant.In general, the seat leak tightness of safety valve of the prior art as shown in the figure can reach 94%, this means when the pressure in the container reach safety valve setting pressure 94% the time valve begin to leak.When valve began to leak, hydrodynamic pressure made valve disc 25 rise from valve seat 33, thereby allowed that fluid is looped around the outlet 13 that the valve disc of 33 li of valve seats enters safety valve from circulation road 35.Owing to the hydrodynamic pressure in the pressurized container reduces because of the safety valve release pressure, thereby make pressure reduce to the reseat pressure of valve, be urged again at valve disc under this pressure and on valve seat 33, also close this valve again.It is poor to be called discharging in the setting pressure of valve and the decompression between the reseat pressure, or is called " discharging " of valve more simply.

According to the present invention, a kind of typical preferred embodiment that improves shape of safety valve 10 is schematically represented by Fig. 2.Referring to Fig. 2, the valve disc 25 of valve 10 of the prior art is replaced by valve disc 40 that comprises feature of the present invention and cover for seat 41.The remaining parts of safety valve 10 still as shown in Figure 1.

Referring to Fig. 2-4, valve disc 40 has one can cooperate with valve disc retaining member 30 and valve disc nut 31 and first combined end 42 by what they were clamped, thereby valve disc is locked on the working position of safety valve.Valve disc 40 also has second a valve seat end 43 that is formed by middle convex surface 44, and at easy annular, the downward intilted conical butt seating face 45 on the lip 50 of song of the annular in an outside.The central body portion 51 of valve disc 40 is provided with an outer groove or ditch 52, and it is along the valve disc Subject Extension on lip 50 opposite sides, and lip 50 makes valve disc have bending properties thus.Can cooperate with the conical butt valve base surface 53 on being positioned at cover for seat 41 first ends at the seating face on the valve disc 45, so that when safety valve cuts out, cut off flowing by cover for seat circulation road 35.Here in the example of illustrated valve of the present invention, seating face 45 and 53 angle measure from the vertical axis (by being orientated shown in Fig. 2-4) by valve disc and cover for seat and are about 60 °.Yet, should be understood that an angle is not conclusive.According to the present invention, the lip 50 of easy song that is formed with the valve disc 40 of seating face 45 on it is allowed seating face bending with means for operation pressure of safety valve and variation of temperature, to keep the maximum contact between valve disc seating face and the cover for seat valve base surface.The operation of preferable exemplary embodiments

Use the proper device (not shown) that safety valve 10 is installed on the pressurized container, fluid will controllably enter the import circulation road of cover for seat 41.The power that helical spring 21 provides abuts against on the cover for seat 41 valve disc 40 by valve rod 15, thereby valve disc seating face 45 is cooperated with cover for seat valve base surface 53, to prevent that the fluid in the pressurized container from outwards flowing through safety valve, reaches the pressure that safety valve setting is opened until hydrodynamic pressure.Fig. 2 has described the valve disc 40 on closed position.Referring to Fig. 3, it has diagrammatically described the outer rim of the valve disc 40 under no pressure and about 70 ambient temperature situations.That lower graphic display before the masterpiece of spring 21 is used on the valve disc position of the lip 50 of seating face 45.When bearing helical spring power, comprise that the outer rim of the valve disc of lip and seating face is bent upwards, as shown in the figure.Then, shown in the graphical representation of the valve disc among Fig. 4, when working environment in 1200psi and 1000 temperature, the helical spring power that acts on the valve disc top makes the valve disc radial expansion with the hydrodynamic pressure and the temperature that act on the valve disc bottom, and the lip of valve disc and seating face are out of shape downwards, as shown in the figure.In the process that temperature and pressure increases along with the spring force that acts on the valve disc, the valve maintenance is closed, the bending properties of valve disc lip makes and forms substantially constant and uniform contact area between valve disc seating face and the present seating face that puts.When pressure when the setting pressure that opens the safety-valve increases, when the degree of pressure of the 97-98% of the setting pressure that reaches valve, valve disc begins antagonistic spring power to move up, valve begins to leak, then move to the fully open position, be released in pressure in the container reducing pressure in this point valve, reset till the required discharging difference of cut-off valve up to reaching valve disc.

A remarkable advantage of valve of the present invention is, as discussed above with the seat leak tightness from about 94% scope that is increased to 97-98%.The pommel face 45 of valve disc trends towards balancedly distributing the fluid from pressurized container, it is flowed to the outlet of valve around valve disc, thereby on valve disc, produce the centering effect and be reduced in disturbance below the valve disc, so that when valve cuts out, valve disc is got back on the cover for seat better.

Though describe and illustrate safety valve of the present invention by the preferable exemplary embodiments of the present invention, should be understood that under the situation that does not exceed the scope of the invention that limits by appended claims and also can make further changes and improvements to valve and valve disc.
